PART I

INFORMATION ABOUT BLACKROCK LIMITED DURATION INCOME TRUST

Item 1. Outside Front Cover

1.a.	The registrant's name is BlackRock Limited Duration Income Trust (the "Fund").

1.b.

The Fund is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as a diversified, closed-end management investment company. The Fund's investment objective is to provide current income and capital appreciation. There can be no assurance that the Fund's investment objective will be achieved or that the Fund's investment program will be successful. The Fund's investment objective may be changed by the Fund's Board of Trustees (the "Board," and each member, a "Trustee") without prior shareholder approval.

The Fund pursues its objective by investing primarily in three distinct asset classes:

intermediate duration, investment grade corporate bonds, mortgage related securities and asset-backed securities and U.S. Government and agency securities;

senior, secured floating rate loans made to corporate and other business entities; and

U.S. dollar-denominated securities of U.S. and non-U.S. issuers rated below investment grade and, to a limited extent, non-U.S. dollar denominated securities of non-U.S. issuers rated below investment grade. Debt securities rated below investment grade commonly are referred to as "junk bonds."

The Fund may invest directly in such securities or synthetically through the use of derivatives. There is no limit on the amount of credit derivative transactions that may be entered into by the Fund. BlackRock Advisors, LLC, the Fund's investment adviser (the "Investment Advisor"), has broad discretion to allocate the Fund's assets among these three principal asset classes.

1.c.	The Fund is offering up to 3,750,000 common shares.

1.d.

You should read this Prospectus, which concisely sets forth information about the Fund, before deciding whether to invest in the Fund's common shares and retain it for future reference. Additional information about the Fund and materials incorporated by reference have been filed with the Securities and Exchange Commission (the "SEC") and are available upon either written or oral request, free of charge, by calling 1-800-882-0052, by writing to the Fund, or may be found on the SEC's website at www.sec.gov. You may also request a copy of this Prospectus, annual and semi-annual reports, other information about the Fund, and/or make investor inquiries by calling 1-800-882-0052, or by writing to the Fund. The Fund's annual and semi-annual reports are also available on the Fund's website at www.blackrock.com free of charge. This reference to BlackRock's website is intended to allow public access to information regarding the Fund and does not, and is not intended to, incorporate BlackRock's website into this Prospectus.

I-1

You should not construe the contents of this Prospectus as legal, tax or financial advice. You should consult with your own professional advisors as to the legal, tax, financial or other matters relevant to the suitability of an investment in the Fund.

The Fund's common shares do not represent a deposit or an obligation of, and are not guaranteed or endorsed by, any bank or other insured depository institution, and are not federally insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.

1.e.

This Prospectus is dated

2014.

1.f.	Not applicable.

1.g.

The Fund's common shares are listed on the New York Stock Exchange ("NYSE") under the symbol "BLW." Sales of the Fund's common shares, if any, under this Prospectus may be made in transactions that are deemed to be "at the market" as defined in Rule 415 under the Securities Act of 1933, as amended (the "Securities Act"), including sales made directly on the NYSE. The minimum price on any day at which Fund common shares may be sold will not be less than the current net asset value ("NAV") per share plus the per share amount of the commission to be paid to the Fund's distributor (the "Minimum Price"), BlackRock Investments, LLC (the "Distributor"). The Fund and the Distributor will determine whether any sales of the Fund's common shares will be authorized on a particular day; the Fund and the Distributor, however, will not authorize sales of the Fund's common shares if the per share price of the shares is less than the Minimum Price. The Fund and the Distributor may also not authorize sales of the Fund's common shares on a particular day even if the per share price of the shares is equal to or greater than the Minimum Price, or may only authorize a fixed number of shares to be sold on any particular day. The Fund and the Distributor will have full discretion regarding whether sales of Fund common shares will be authorized on a particular day and, if so, in what amounts. As of August 31, 2014, the last reported sale price for the Fund's common shares on the NYSE was $16.81 per share.

The Distributor has entered into a dealer agreement, dated May 2, 2014 (the "Dealer Agreement"), with UBS Securities LLC (the "Dealer") with respect to the Fund relating to the common shares offered by this Prospectus. In accordance with the terms of the Dealer Agreement, the Fund may offer and sell its common shares from time to time through the Dealer as sub-placement agent for the offer and sale of its common shares. The Fund will compensate the Distributor with respect to sales of common shares at a commission rate of 1.00% of the gross proceeds of the sale of the Fund's common shares. Out of this commission, the Distributor will compensate broker-dealers at a rate of up to 0.80% of the gross sales proceeds of the sale of the Fund's common shares sold by that broker-dealer.

1.h.	Neither the SEC nor any state securities commission has approved or disapproved of these securities or determined if this Prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

1.i.

The Fund's common shares have traded both at a premium and a discount to NAV. The Fund cannot predict whether its common shares will trade at a premium or discount to NAV in the future. The provisions of the 1940 Act generally require that the public offering price of common shares (less any underwriting commissions and discounts) must equal or exceed the NAV per share of a company's common shares (calculated within 48 hours of pricing). The Fund's issuance of common shares may have an adverse effect on prices for the Fund's common shares in the secondary market by increasing the number of common shares available in the market, which may put downward pressure on the market price for the Fund's common shares. Common shares of closed-end investment companies frequently trade at a discount from NAV, which may increase investors' risk of loss.

1.j.

Investing in the Fund's common shares involves certain risks that are described in Item 8.3 beginning on page I-23 of Part I of this Prospectus, and under Item 8 in Part II of this Prospectus under "Risk Factors," beginning on page II-36 of Part II. Certain of these risks are summarized in Item 3.2 beginning on page I-10 of Part I of this Prospectus.

Offering expenses borne by the Fund (as a percentage of offering price)	0.02%(2)
Dividend reinvestment plan fees	$0.02 per share for open-market purchases of common shares(3)

	Percentage of net assets attributable to common shares
Annual Expenses
Management fees(4)	0.79%
Interest expense(5)	0.21%
Other expenses(6)	0.14%
Total annual expenses(7)	1.14%

(1)

Represents the estimated commission with respect to the Fund's common shares being sold in this offering. There is no guarantee that there will be any sales of the Fund's common shares pursuant to this Prospectus. Actual sales of the Fund's common shares under this Prospectus, if any, may be less than as set forth under "Capitalization" below. In addition, the price per share of any such sale may be greater or less than the price set forth under "Capitalization" below, depending on market price of the Fund's common shares at the time of any such sale.

(2)

Based on Minimum Price as of August 31, 2014. Offering expenses generally include, but are not limited to, the preparation, review and filing with the SEC of the Fund's registration statement (including this Prospectus), the preparation, review and filing of any associated marketing or similar materials, costs associated with the printing, mailing or other distribution of the Prospectus and/or marketing materials, associated filing fees, NYSE listing fees, and legal and auditing fees associated with the offering.

(3)

The Reinvestment Plan Agent's (as defined under "Item 10—Dividend Reinvestment Plan" in Part II) fees for the handling of the reinvestment of dividends will be paid by the Fund. However, you will pay a $0.02 per share fee incurred in connection with open-market purchases, which will be deducted from the value of the dividend. You will also be charged a $2.50 sales fee and pay a $0.15 per share fee if you direct the Reinvestment Plan Agent to sell your common shares held in a dividend reinvestment account. Per share fees include any applicable brokerage commissions the Reinvestment Plan Agent is required to pay.

(4)

The Fund currently pays BlackRock Advisors, LLC, its investment adviser, a contractual management fee at an annual rate of 0.55% based on an aggregate of (i) the Fund's average weekly net assets and (ii) the proceeds of any outstanding borrowings used for leverage ("average weekly Managed Assets"). The Fund uses leverage, in the form of reverse repurchase agreements, which as of August 31, 2014 amounted to approximately 30% of the Fund's Managed Assets (approximately 44% of the Fund's net assets). "Managed Assets" means the total assets of the Fund (including any assets attributable to money borrowed for investment purposes) minus the sum of the Fund's accrued liabilities (other than money borrowed for investment purposes). The Fund's net assets attributable to common shares are the Fund's Managed Assets minus the value of the Fund's assets attributable to money borrowed for investment purposes. Thus, when the Fund uses leverage, its net assets attributable to common shares are less than its Managed Assets and its expenses (including the management fee) stated as a percentage of its net assets attributable to common shares are greater than they would be if stated as a percentage of its Managed Assets. This table reflects the fact that you, as a common shareholder, bear the expenses of the Fund's use of leverage in the form of higher fees as a percentage of the Fund's net assets attributable to common shares than if the Fund did not use leverage.

I-3

(5)

Reflects leverage, in the form of reverse repurchase agreements, in an amount equal to approximately 30% of the Fund's Managed Assets (approximately 44% of the Fund's net assets) as of August 31, 2014. The interest expense borne by the Fund will vary over time in accordance with the level of the Fund's use of leverage and variations in market interest rates. Interest expense is required to be treated as an expense of the Fund for accounting purposes.

(6)

Based on the fiscal year ended August 31, 2014.

(7)

Represents total annual expenses including interest expense. The total annual expense excluding interest expense is 0.92%.

The Investment Advisor voluntarily agreed to waive its investment advisory fees by the amount of investment advisory fees the Fund pays to the Investment Advisor indirectly through its investment in affiliated money market funds. However, the Investment Advisor does not waive its investment advisory fees by the amount of investment advisory fees paid in connection with the Fund's investment in other affiliated investment companies, if any. This waiver amounted to less than 0.01% of the Fund's net assets attributable to common shares for the fiscal year ended August 31, 2014. See Item 20, below.

The purpose of the foregoing table and the example below is to help you understand all fees and expenses that you, as a holder of common shares of the Fund, bear directly or indirectly. The foregoing table should not be considered a representation of the Fund's future expenses. Actual future expenses may be greater or less than shown. Except where the context suggests otherwise, whenever this Prospectus contains a reference to fees or expenses paid by "you" or "us" or that "we" will pay fees or expenses, shareholders will indirectly bear such fees or expenses as investors in the Fund.

The following example illustrates the expenses (including the sales load of $10 and offering costs of $0.17 that you would pay on a $1,000 investment in common shares, assuming (i) total annual expenses of 1.14% of net assets attributable to common shares in years 1 through 10, and (ii) a 5% annual return:

	1 Year	3 Years	5 Years	10 Years
Total expenses incurred	$22	$46	$72	$147

The example should not be considered a representation of future expenses. The example assumes that the "Other expenses" set forth in the Annual Expenses table are accurate and that all dividends and distributions are reinvested at NAV. Actual expenses may be greater or less than those assumed. Moreover, the Fund's actual rate of return may be greater or less than the hypothetical 5% return shown in the example.

Capitalization

The Fund may offer and sell up to 3,750,000 common shares, $0.001 par value per share, from time to time through the Dealer as sub-placement agent under this Prospectus. There is no guarantee that there will be any sales of the Fund's common shares pursuant to this Prospectus. The table below assumes that the Fund will sell 3,750,000 common shares at a price of $18.28 per share (the Minimum Price – i.e., NAV plus sales load per share of the Fund's common shares – on August 31, 2014). Actual sales, if any, of the Fund's common shares under this Prospectus may be greater or less than $18.28 per share, depending on the market price of the Fund's common shares at the time of any such sale and/or the Fund's NAV for purposes of calculating the Minimum Price. The Fund and the Distributor will determine whether any sales of the Fund's common shares will be authorized on a particular day; the Fund and the Distributor, however, will not authorize sales of the Fund's common shares if the per share price of the shares is less than the Minimum Price. The Fund and the Distributor may also not authorize sales of the Fund's common shares on a particular day even if the per share price of the shares is equal to or greater than the Minimum Price, or may only authorize a fixed number of shares to be sold on any particular day. The Fund and the Distributor will have full discretion regarding whether sales of Fund common shares will be authorized on a particular day and, if so, in what amounts.

The following table sets forth the Fund's capitalization (1) on a historical basis as of August 31, 2014 (audited); and (2) on a pro forma as adjusted basis to reflect the assumed sale of 3,750,000 common shares at $18.28 per share (the Minimum Price – i.e., NAV plus sales load per share of the Fund's common shares – on August 31, 2014), in an offering under this Prospectus, after deducting the assumed commission of

The Fund	BlackRock Limited Duration Income Trust is registered under the 1940 Act, as a diversified, closed-end management investment company and has been operational since 2003.

The Offering	The Fund is offering up to 3,750,000 common shares in transactions that are deemed to be "at the market" as defined in Rule 415 under the Securities Act, including sales made directly on the NYSE. The minimum price on any day at which Fund common shares may be sold will not be less than the current NAV per share plus the per share amount of the commission to be paid to the Distributor. The Fund and the Distributor will determine whether any sales of the Fund's common shares will be authorized on a particular day; the Fund and the Distributor, however, will not authorize sales of the Fund's common shares if the per share price of the shares is less than the Minimum Price. The Fund and the Distributor may also not authorize sales of the Fund's common shares on a particular day even if the per share price of the shares is equal to or greater than the Minimum Price, or may only authorize a fixed number of shares to be sold on any particular day. The Fund and the Distributor will have full discretion regarding whether sales of Fund common shares will be authorized on a particular day and, if so, in what amounts. As of August 31, 2014, the last reported sale price for the Fund's common shares on the NYSE was $16.81 per share. The Distributor has entered into the Dealer Agreement with the Dealer with respect to the Fund relating to the common shares offered by this Prospectus. In accordance with the terms of the Dealer Agreement, the Fund may offer and sell its common shares from time to time through the Dealer as sub-placement agent for the offer and sale of its common shares. The Fund will compensate the Distributor with respect to sales of common shares at a commission rate of 1.00% of the gross proceeds of the sale of the Fund's common shares. Out of this commission, the Distributor will compensate broker-dealers at a rate of up to 0.80% of the gross sales proceeds of the sale of the Fund's common shares sold by that broker-dealer. The Fund's common shares have traded both at a premium and a discount to NAV. The Fund cannot predict whether its common shares will trade at a premium or discount to NAV in the future. The provisions of the 1940 Act generally require that the public offering price of common shares (less any underwriting commissions and discounts) must equal or exceed the NAV per share of a company's common shares (calculated within 48 hours of pricing). The Fund's issuance of common shares may have an adverse

I-5

	effect on prices for the Fund's common shares in the secondary market by increasing the number of common shares available, which may put downward pressure on the market price for the Fund's common shares. Common shares of closed-end investment companies frequently trade at a discount from NAV, which may increase investors' risk of loss.

Investment Objective	The Fund's investment objective is to provide current income and capital appreciation. There can be no assurance that the Fund's investment objective will be achieved or that the Fund's investment program will be successful. The Fund's investment objective may be changed by the Board without prior shareholder approval.

Investment Strategy	BlackRock Advisors, LLC is the Fund's investment adviser. BlackRock Financial Management, Inc., the Investment Advisor's affiliate, served as the sub-adviser for the Fund until July 1, 2014 when the sub-advisory agreement between the Investment Advisor and BlackRock Financial Management, Inc. expired. In selecting securities for the Fund, BlackRock will seek to identify issuers and industries that BlackRock believes are likely to experience stable or improving financial conditions. BlackRock's analysis will include: · credit research on the issuers' financial strength; · assessment of the issuers' ability to meet principal and interest payments; · general industry trends; · the issuers' managerial strength; · changing financial conditions; · borrowing requirements or debt maturity schedules; and · the issuers' responsiveness to changes in business conditions and interest rates. BlackRock will consider relative values among issuers based on anticipated cash flow, interest or dividend coverage, asset coverage and earnings prospects. Using these tools, BlackRock will seek to add consistent value and control performance volatility consistent with the Fund's investment objectives and policies. BlackRock believes this strategy should enhance the Fund's ability to achieve its investment objective. In managing the assets of the Fund, BlackRock will utilize an active management approach that stresses the flexibility to reallocate investments as appropriate. BlackRock will diversify the Fund's portfolio of assets in an effort to minimize exposure to individual securities, issuers and industries. BlackRock's analysis continues on an ongoing basis for any securities in which the Fund has invested. Although BlackRock uses due care in making such analysis, there can be no assurance that such analysis will reveal factors that may impair the value of such securities.

Investment Policies	The Fund pursues its objective by investing primarily in three distinct asset classes: · intermediate duration, investment grade corporate bonds, mortgage related securities and asset-backed securities and U.S. Government and agency securities; · senior, secured floating rate loans made to corporate and other business entities; and · U.S. dollar-denominated securities of U.S. and non-U.S. issuers rated below investment grade and, to a limited extent, non-U.S. dollar denominated securities of non-U.S. issuers rated below investment grade. The Fund may invest directly in such securities or synthetically through the use of

I-6

derivatives. The Investment Advisor has broad discretion to allocate the Fund's assets among these three principal asset classes.

The Fund's portfolio normally has an average portfolio duration of less than five years (including the effect of anticipated leverage), although it may be longer from time to time depending on market conditions. In comparison to maturity (which is the date on which the issuer of a debt instrument is obligated to repay the principal amount), duration is a measure of the price volatility of a debt instrument as a result in changes in market rates of interest, based on the weighted average timing of the instrument's expected principal and interest payments. Specifically, duration measures the anticipated percentage change in NAV that is expected for every percentage point change in interest rates. The two have an inverse relationship. Duration can be a useful tool to estimate anticipated price changes to a fixed pool of income securities associated with changes in interest rates. For example, a duration of five years means that a 1% decrease in interest rates will increase the net asset value of the portfolio by approximately 5%; if interest rates increase by 1%, the net asset value will decrease by 5%. However, in a managed portfolio of fixed income securities having differing interest or dividend rates or payment schedules, maturities, redemption provisions, call or prepayment provisions and credit qualities, actual price changes in response to changes in interest rates may differ significantly from a duration-based estimate at any given time. Actual price movements experienced by a portfolio of fixed income securities will be affected by how interest rates move (i.e., changes in the relationship of long term interest rates to short term interest rates), the magnitude of any move in interest rates, actual and anticipated prepayments of principal through call or redemption features, the extension of maturities through restructuring, the sale of securities for portfolio management purposes, the reinvestment of proceeds from prepayments on and from sales of securities, and credit quality-related considerations whether associated with financing costs to lower credit quality borrowers or otherwise, as well as other factors. Accordingly, while duration maybe a useful tool to estimate potential price movements in relation to changes in interest rates, investors are cautioned that duration alone will not predict actual changes in the net asset or market value of the Fund's shares and that actual price movements in the Fund's portfolio may differ significantly from duration-based estimates. Duration differs from maturity in that it takes into account a security's yield, coupon payments and its principal payments in addition to the amount of time until the security finally matures. As the value of a security changes over time, so will its duration. Prices of securities with longer durations tend to be more sensitive to interest rate changes than securities with shorter durations. In general, a portfolio of securities with a longer duration can be expected to be more sensitive to interest rate changes than a portfolio with a shorter duration.

The Fund is intended to have a relatively low level of interest rate risk compared to investment portfolios of similar credit quality but with longer durations. Certain of the Fund's other strategies, however, may result in an above average amount of risk and volatility or loss of principal. Therefore, this type of investment may be inappropriate for your risk profile. There is no assurance that the Fund will achieve its investment objective. The Fund is not intended as a complete investment program.

The Fund anticipates that, under normal market conditions, a significant portion of its Managed Assets will be invested in securities rated below investment grade, such as those rated Ba or lower by Moody's Investor's Service, Inc. ("Moody's") and BB or lower by Standard & Poor's Corporation Ratings Services, a division of The McGraw-Hill Companies, Inc. ("S&P") or securities comparably rated by other rating agencies or in unrated securities determined by the Investment Advisor to be of comparable quality. High yield securities commonly are referred to as "junk" bonds. The Fund may invest in individual securities of any credit quality.

The Fund may also invest in investment grade securities, which are securities rated at

I-7

	least BBB– as determined by S&P, Baa3 as determined by Moody's or, if unrated, determined to be of comparable quality by the Investment Advisor. When Investment Advisor believes it to be in the best interests of the Fund's shareholders, the Fund will reduce its investment in lower grade securities and, in certain market conditions, the Fund may invest none of its assets in lower grade securities. The Fund may invest without limitation in U.S. dollar denominated securities of non-U.S. issuers and, to a limited extent, non-U.S. dollar-denominated securities of non-U.S. issuers ("Foreign Securities"), including up to 20% of its Managed Assets in issuers located in emerging market countries. The Fund can hold no more than 10% of its Managed Assets in non-U.S. dollar-denominated Foreign Securities. The Fund may invest in mortgage-related securities, which include collateralized mortgage obligations, stripped mortgage-backed securities, mortgage pass-through securities, interests in real estate mortgage investment conduits ("REMICs"), real estate investment trusts ("REITs"), including debt and preferred stock issued by REITs, as well as other real estate-related securities. The mortgage-related securities in which the Fund may invest include those with fixed, floating or variable interest rates, those with interest rates that change based on multiples of changes in a specified index of interest rates and those with interest rates that change inversely to changes in interest rates, as well as those that do not bear interest. The Fund may invest in residential and commercial mortgage-related securities issued by governmental entities and private issuers, including subordinated mortgage-related securities. Although the Fund may invest in residential and commercial mortgage-related securities issued by governmental entities and private issuers, the Fund expects that most of such investments will be limited to commercial mortgage-related securities, in which the Fund will not invest more than 15% of its Managed Assets. For a discussion of risk factors that may affect the Fund's ability to achieve its investment objective, see "Risk Factors" under Item 8 in Part II.

Leverage	The Fund currently utilizes leverage for investment purposes in the form of reverse repurchase agreements. As of August 31, 2014, this leverage represented approximately 31% of the Fund's Managed Assets (approximately 44% of the Fund's net assets). The Fund may borrow from banks and other financial institutions and may also borrow additional funds using such investment techniques as the Investment Advisor may from time to time determine. Of these investment techniques, the Fund expects primarily to use reverse repurchase agreements and dollar rolls. The Fund has the ability to utilize leverage through borrowings in an amount up to 33 1/3% of the value of its Managed Assets (which includes the amount obtained from such borrowings). The Fund also has the ability to utilize leverage through the issuance of preferred shares in an amount up to 50% of the value of its Managed Assets (which includes the amount obtained from such issuance). The Fund does not currently anticipate issuing any preferred shares; thus, the Fund will limit its borrowing to 33 1/3% of the Fund's Managed Assets. If preferred shares are issued, however, the Fund's borrowing limit will be proportionately reduced so that the Fund's aggregate leverage will not exceed 33 1/3% of the Fund's Managed Assets. See "Leverage" under Item 8 in Part II and the discussion of the Fund's capital structure under Item 10 in Part II. The use of leverage is subject to numerous risks. When leverage is employed, the NAV and market price of the common shares and the yield to holders of common shares will be more volatile than if leverage were not used. For example, a rise in short-term interest rates, which currently are near historically low levels, will cause the Fund's NAV to

I-8

	decline more than if the Fund had not used leverage. A reduction in the Fund's NAV may cause a reduction in the market price of its common shares. The Fund cannot assure you that the use of leverage will result in a higher yield on the common shares. When the Fund uses leverage, the management fee payable to the Investment Advisor will be higher than if the Fund did not use leverage because these fees are calculated on the basis of the Fund's Managed Assets, which include the proceeds of leverage. The Fund's leveraging strategy may not be successful. See "Risk Factors—Leverage Risk" under Item 8 in Part II.

Investment Advisor	BlackRock Advisors, LLC is the Fund's investment adviser. BlackRock Financial Management, Inc., the Investment Advisor's affiliate, served as the sub-adviser for the Fund until July 1, 2014 when the sub-advisory agreement between the Investment Advisor and BlackRock Financial Management, Inc. expired. The Investment Advisor receives an annual fee, payable monthly, in an amount equal to 0.55% of the average weekly value of the Fund's Managed Assets.

Distributions	The Fund intends to make regular monthly cash distributions of all or a portion of its net investment income to holders of the Fund's common shares. The Fund intends to pay any capital gains distributions at least annually. A return of capital distribution may involve a return of the shareholder's original investment. Though not currently taxable, such a distribution may lower a shareholder's basis in the Fund, thus potentially subjecting the shareholder to future tax consequences in connection with the sale of Fund shares, even if sold at a loss to the shareholder's original investment. When total distributions exceed total return performance for the period, the difference will reduce the Fund's total assets and NAV and, therefore, could have the effect of increasing the Fund's expense ratio and reducing the amount of assets the Fund has available for long term investment. Shareholders will automatically have all dividends and distributions reinvested in common shares of the Fund in accordance with the Fund's dividend reinvestment plan, unless an election is made to receive cash by contacting the Reinvestment Plan Agent (as defined herein), at (800) 699-1236. See "Dividend Reinvestment Plan" under Item 10 in Part II. The Fund reserves the right to change its distribution policy and the basis for establishing the rate of its monthly distributions at any time and may do so without prior notice to common shareholders. See Item 10.1 in Part I and "Distributions" under Item 10 in Part II.

Listing	The Fund's common shares are listed on the NYSE under the symbol "BLW."

Custodian and Transfer Agent	State Street Bank and Trust Company serves as the Fund's custodian, and Computershare Trust Company, N.A. serves as the Fund's transfer agent.

Administrator	State Street Bank and Trust Company serves as the Fund's administrator and fund accountant.

Market Price of Shares	Common shares of closed-end investment companies frequently trade at prices lower than their NAV. The Fund cannot assure you that its common shares will trade at a price higher than or equal to NAV. The Fund's common shares trade in the open market at market prices that are a function of several factors, including dividend levels (which are in turn affected by expenses), NAV, call protection for portfolio securities, portfolio credit quality, liquidity, dividend stability, relative demand for and supply of the common shares in the market, general market and economic conditions and other factors. The Fund's common shares are designed primarily for long-term investors and you should not purchase common shares of the Fund if you intend to sell them shortly after purchase.

	The issuance of additional common shares pursuant to this Prospectus may also have an adverse effect on prices for the Fund's common shares in the secondary market by increasing the supply of common shares available for sale.

Special Risk Considerations	An investment in the Fund's common shares involves risk. You should consider carefully the risks identified below, which are described in detail under "Risk Factors" beginning on page II-36 of Part II of this Prospectus. Principal risks of investing in the Fund include: · Interest Rate Risk. Interest rate risk is the risk that prices of bonds and other fixed-income securities will increase as interest rates fall and decrease as interest rates rise. · Issuer Risk. The value of fixed income securities may decline for a number of reasons which directly relate to the issuer, such as management performance, financial leverage, reduced demand for the issuer's goods and services, historical and prospective earnings of the issuer and the value of the assets of the issuer. · Credit Risk. Credit risk is the risk that one or more fixed income securities in the Fund's portfolio will decline in price or fail to pay interest or principal when due because the issuer of the security experiences a decline in its financial status. · Prepayment Risk. During periods of declining interest rates, borrowers may exercise their option to prepay principal earlier than scheduled. · Reinvestment Risk. Reinvestment risk is the risk that income from the Fund's portfolio will decline if the Fund invests the proceeds from matured, traded or called fixed income securities at market interest rates that are below the Fund portfolio's current earnings rate. · Duration and Maturity Risk. The Fund may incur costs in seeking to adjust the portfolio average duration or maturity. There can be no assurance that the Investment Advisor's assessment of current and projected market conditions will be correct or that any strategy to adjust the portfolio's duration or maturity will be successful at any given time. · Corporate Bonds Risk. The market value of a corporate bond generally may be expected to rise and fall inversely with interest rates. The market value of intermediate and longer-term corporate bonds is generally more sensitive to changes in interest rates than is the market value of shorter-term corporate bonds. The market value of a corporate bond also may be affected by factors directly related to the issuer, such as investors' perceptions of the creditworthiness of the issuer, the issuer's financial performance, perceptions of the issuer in the market place, performance of management of the issuer, the issuer's capital structure and use of financial leverage and demand for the issuer's goods and services. · Mortgage Related Securities Risks. The risks associated with MBS include: credit risk associated with the performance of the underlying mortgage properties and of the borrowers owning these properties; risks associated with their structure and execution (including the collateral, the process by which principal and interest payments are allocated and distributed to investors and how credit losses affect the issuing vehicle and the return to investors in such MBS); whether the collateral represents a fixed set of specific assets or accounts, whether the underlying collateral assets are revolving or closed-end, under what terms (including maturity of the MBS) any remaining balance in the accounts may revert to the issuing entity and the extent to which the entity that is the actual source of the collateral assets is obligated to provide support to the issuing vehicle or to the investors in such MBS; risks associated with the servicer of the underlying mortgages; adverse changes in economic conditions

I-10

and circumstances, which are more likely to have an adverse impact on MBS secured by loans on certain types of commercial properties than on those secured by loans on residential properties; prepayment risk, which can lead to significant fluctuations in the value of the MBS; loss of all or part of the premium, if any, paid; and decline in the market value of the security, whether resulting from changes in interest rates, prepayments on the underlying mortgage collateral or perceptions of the credit risk associated with the underlying mortgage collateral.

· Below Investment Grade Securities Risk. The Fund may invest in securities that are rated, at the time of investment, below investment grade quality (rated Ba/BB or below, or unrated but judged to be of comparable quality by the Investment Advisor), which are commonly referred to as "high yield" or "junk" bonds and are regarded as predominantly speculative with respect to the issuer's capacity to pay interest and repay principal. Issuers of high yield bonds are not perceived to be as strong financially as those with higher credit ratings. These issuers are more vulnerable to financial setbacks and recession than more creditworthy issuers, which may impair their ability to make interest and principal payments.

· Senior Loans Risk. Senior loans typically hold the most senior position in the capital structure of the issuing entity, are typically secured with specific collateral and typically have a claim on the assets and/or stock of the borrower that is senior to that held by subordinated debt holders and stockholders of the borrower. The Fund's investments in senior loans are typically below investment grade and are considered speculative because of the credit risk of their issuer.

Item 8. Description of the Fund

The Fund was organized as a Delaware statutory trust on May 16, 2003, pursuant to an Agreement and Declaration of Trust, as subsequently amended and restated, governed by the laws of the State of Delaware, and commenced operations on July 30, 2003. The Fund is registered under the 1940 Act as a diversified, closed-end management investment company. The Fund's principal office is located at 100 Bellevue Parkway, Wilmington, Delaware 19809, and its telephone number is (800) 882-0052.

2.	Investment Objectives and Principal Investment Policies:

Investment Objective. The Fund's investment objective is to provide current income and capital appreciation. The Fund pursues its objective by investing primarily in three distinct asset classes:

intermediate duration, investment grade corporate bonds, mortgage related securities and asset-backed securities and U.S. Government and agency securities;

senior, secured floating rate loans made to corporate and other business entities; and

The Fund may invest directly in such securities or synthetically through the use of derivatives. The Investment Advisor has broad discretion to allocate the Fund's assets among these three principal asset classes.

There can be no assurance that the Fund's investment objective will be achieved or that the Fund's investment program will be successful. The Fund's investment objective may be changed by the Board without prior shareholder approval.

Duration. The Fund's portfolio normally has an average portfolio duration of less than five years (including the effect of anticipated leverage), although it may be longer from time to time depending on market conditions. In comparison to maturity (which is the date on which the issuer of a debt instrument is obligated to repay the principal amount), duration is a measure of the price volatility of a debt instrument as a result in changes in market rates of interest, based on the weighted average timing of the instrument's expected principal and interest payments. Specifically, duration measures the anticipated percentage change in NAV that is expected for every percentage point change in interest rates. The two have an inverse relationship. Duration differs from maturity in that it takes into account a security's yield, coupon payments and its principal payments in addition to the amount of time until the security finally matures. As the value of a security changes over time, so will its duration. Prices of securities with longer durations tend to be more sensitive to interest rate changes than securities with shorter durations. In general, a portfolio of securities with a longer duration can be expected to be more sensitive to interest rate changes than a portfolio with a shorter duration.

Corporate Bonds. The Fund may invest in corporate bonds.

High Yield Securities. The Fund anticipates that, under normal market conditions, a significant portion of its Managed Assets will be invested in securities rated below investment grade, such as those rated Ba or lower by Moody's and BB or lower by S&P or securities comparably rated by other rating agencies or in unrated securities determined by the Investment Advisor to be of comparable quality. High yield securities commonly are referred to as "junk" bonds. The Fund may invest in individual securities of any credit quality.

The Fund may also invest in investment grade securities, which are securities rated at least BBB– as determined by S&P, Baa3 as determined by Moody's or, if unrated, determined to be of comparable quality by the Investment Advisor. When Investment Advisor believes it to be in the best interests of the Fund's shareholders, the Fund will

I-15

reduce its investment in lower grade securities and, in certain market conditions, the Fund may invest none of its assets in lower grade securities.

See "Appendix A—Ratings of Securities" for information concerning rating categories.

Foreign Securities. The Fund may invest without limitation in U.S. dollar denominated securities of non-U.S. issuers and, to a limited extent, non-U.S. dollar-denominated securities of non-U.S. issuers, including up to 20% of its Managed Assets in issuers located in emerging market countries. The Fund can hold no more than 10% of its Managed Assets in non-U.S. dollar-denominated Foreign Securities.

Foreign Securities may include debt securities issued by foreign governments and other sovereign entities and debt securities issued by foreign corporations or supranational entities and securities denominated in U.S. dollars or, to a limited extent (as described above), in foreign currencies or multinational currency units. The Fund may invest in Brady Bonds and other sovereign debt of countries that have restructured or are in the process of restructuring their debt pursuant to the Brady Plan, which are viewed as speculative investments. The Fund may also purchase debt securities of supranational organizations such as the European Coal and Steel Community, the European Economic Community and the World Bank, which are chartered to promote economic development.

U.S. Government Securities. The Fund may invest in debt securities issued or guaranteed by the U.S. Government, its agencies or instrumentalities including but not limited to: (1) U.S. Treasury obligations, which differ in their interest rates, maturities and times of issuance, such as U.S. Treasury bills (maturity of one year or less), U.S. Treasury notes (maturity of one to ten years), and U.S. Treasury bonds (generally maturities of greater than ten years), including the principal components or the interest components issued by the U.S. Government under the separate trading of registered interest and principal securities program (i.e., "STRIPS"), all of which are backed by the full faith and credit of the United States; and (2) obligations issued or guaranteed by U.S. Government agencies or instrumentalities, including government guaranteed mortgage-related securities, some of which are backed by the full faith and credit of the U.S. Treasury, some of which are supported by the right of the issuer to borrow from the U.S. Government and some of which are backed only by the credit of the issuer itself.

Mortgage-Related Securities. The Fund may invest in mortgage-related securities, which include collateralized mortgage obligations, stripped mortgage-backed securities, mortgage pass-through securities, interests in real estate mortgage investment conduits, real estate investment trusts, including debt and preferred stock issued by REITs, as well as other real estate-related securities. The mortgage-related securities in which the Fund may invest include those with fixed, floating or variable interest rates, those with interest rates that change based on multiples of changes in a specified index of interest rates and those with interest rates that change inversely to changes in interest rates, as well as those that do not bear interest. The Fund may invest in residential and commercial mortgage-related securities issued by governmental entities and private issuers, including subordinated mortgage-related securities. Although the Fund may invest in residential and commercial mortgage-related securities issued by governmental entities and private issuers, the Fund expects that most of such investments will be limited to commercial mortgage-related securities, in which the Fund will not invest more than 15% of its Managed Assets.

Asset-Backed Securities. Asset-backed securities are a form of structured debt obligations. The securitization techniques used for asset-backed securities are similar to those used for mortgage-related securities. The collateral for these securities may include home equity loans, automobile and credit card receivables, boat loans, computer leases, airplane leases, mobile home loans, recreational vehicle loans and hospital account receivables. The Fund may invest in these and other types of asset-backed securities that may be developed in the future.

Senior Loans. In addition to senior, secured floating rate loans made to corporate and other business entities, the Fund may also purchase unsecured loans, other floating rate debt securities, and credit-linked notes.

A senior loan is typically originated, negotiated and structured by a U.S. or foreign commercial bank, insurance company, finance company or other financial institution (the "Agent") for a group of loan investors ("Loan Investors"). The Fund may purchase "Assignments" from the Agent or other Loan Investors. The Fund also may invest in "Participations." Participations by the Fund in a Loan Investor's portion of a senior loan typically will result in the Fund having a contractual relationship only with such Loan Investor, not with the borrower, whereas the Fund, as a purchaser of an Assignment, would typically succeed to all the rights and obligations under the loan agreement of the assigning Loan Investor and become a Loan Investor under the loan agreement with the same rights and

I-16

obligations as the assigning Loan Investor. The Fund will only acquire Participations if the Loan Investor selling the Participation, and any other persons interpositioned between the Fund and the Loan Investor, are believed by the Investment Advisor to be creditworthy at the time they enter into such transactions.

The Fund may also acquire equity securities or debt securities (including non-dollar denominated debt securities) issued in exchange for a senior loan or issued in connection with the debt restructuring or reorganization of a borrower, or if such acquisition, in the judgment of the Investment Advisor, may enhance the value of a senior loan or would otherwise be consistent with the Fund's investment policies.

Collateralized Bond Obligations. The Fund may invest in collateralized bond obligations ("CBOs"), which are structured securities backed by a diversified pool of high yield, public or private fixed income securities. Under normal market conditions, the Fund expects to invest in the lower tranches of CBOs.

Derivatives. The Fund may purchase and sell futures contracts, enter into various interest rate transactions such as swaps, caps, floors or collars, currency transactions such as currency forward contracts, currency futures contracts, currency swaps or options on currency or currency futures and swap contracts (including, but not limited to, credit default swaps) and may purchase and sell exchange-listed and over-the-counter put and call options on securities and swap contracts, financial indices and futures contracts and use other derivative instruments or management techniques. The Fund also may purchase derivative instruments that combine features of these instruments.

Other Investment Companies. The Fund may invest up to 10% of its Managed Assets in securities of other open- or closed-end investment companies that invest primarily in bonds of the types in which the Fund may invest directly. The Fund generally expects to invest in other investment companies either during periods when it has large amounts of uninvested cash, such as the period shortly after the Fund receives the proceeds of the offering of its common shares, or during periods when there is a shortage of attractive opportunities in the fixed income market.

Other Investment Policies:

Leverage. The Fund currently utilizes leverage for investment purposes in the form of reverse repurchase agreements. As of August 31, 2014, this leverage represented approximately 31% of the Fund's Managed Assets (approximately 44% of the Fund's net assets). The Fund may borrow from banks and other financial institutions and may also borrow additional funds using such investment techniques as the Investment Advisor may from time to time determine. Of these investment techniques, the Fund expects primarily to use reverse repurchase agreements and dollar rolls. The Fund has the ability to utilize leverage through borrowings in an amount up to 33 1/3% of the value of its Managed Assets (which includes the amount obtained from such borrowings).

The Fund also has the ability to utilize leverage through the issuance of preferred shares in an amount up to 50% of the value of its Managed Assets (which includes the amount obtained from such issuance). The Fund does not currently anticipate issuing any preferred shares; thus, the Fund will limit its borrowing to 33 1/3% of the Fund's Managed Assets. If preferred shares are issued, however, the Fund's borrowing limit will be proportionately reduced so that the Fund's aggregate leverage will not exceed 33 1/3% of the Fund's Managed Assets.

The Fund generally will not utilize leverage if it anticipates that the Fund's leveraged capital structure would result in a lower return to shareholders than that obtainable over time with an unleveraged capital structure. Use of financial leverage creates an opportunity for total return for the shareholders, but at the same time, creates special risks and there can be no assurance that a leveraging strategy will be successful during any period in which it is employed. There can be no assurance that the Fund will borrow in order to leverage its assets or, if it does, what percentage of the Fund's assets such borrowings will represent.

Variable and Floating Rate Instruments. The Fund may invest in floating rate debt instruments ("floaters"). The Fund also may invest in inverse floating rate debt instruments ("inverse floaters").

Stripped Securities. The Fund may invest in zero-coupon U.S. Treasury securities, which are Treasury notes and bonds that have been stripped of their unmatured interest coupons, the coupons themselves and receipts or certificates representing interests in such stripped debt obligations and coupons. Such stripped securities also are issued by corporations and financial institutions which constitute a proportionate ownership of the issuer's pool of underlying U.S. Treasury securities.

I-17

Treasury Inflation-Protected Securities. The Fund may invest in U.S. Treasury inflation-protected securities ("TIPS") that are designed to provide an investment vehicle that is not vulnerable to inflation.

Pay-In-Kind Bonds. The Fund may invest in pay-in-kind, or "PIK," bonds.

Structured Investments. The Fund may invest a portion of its assets in interests in entities organized and operated solely for the purpose of restructuring the investment characteristics of securities. This type of restructuring involves the deposit with or purchase by an entity, such as a corporation or a trust, of specified instruments and the issuance by that entity of one or more classes of securities ("Structured Investments") backed by, or representing interests in the underlying instruments. The cash flow on the underlying instruments may be apportioned among the newly issued Structured Investments to create securities with different investment characteristics such as varying maturities, payment priorities and interest rate provisions, and the extent of the payments made with respect to Structured Investments is dependent on the extent of the cash flow on the underlying instruments. The Fund is permitted to invest in a class of Structured Investments that is either subordinated or not subordinated to the right of payment of another class.

Project Loans. The Fund may invest in project loans, which are fixed income securities of issuers whose revenues are primarily derived from mortgage loans to multi-family, nursing home and other real estate development projects.

Preferred Securities. The Fund may invest in preferred securities, including preferred securities that may be converted into common stock or other securities of the same or a different issuer. The types of preferred securities in which the Fund may invest include trust preferred securities.

Convertible Securities. The Fund may invest in convertible securities. A convertible security is a bond, debenture, note, preferred security or other security that may be converted into or exchanged for a prescribed amount of common stock or other equity security of the same or a different issuer within a particular period of time at a specified price or formula.

Money Market Obligations of Domestic Banks, Foreign Banks and Foreign Branches of U.S. Banks. The Fund may purchase bank obligations, such as certificates of deposit, notes, bankers' acceptances and time deposits, including instruments issued or supported by the credit of U.S. or foreign banks or savings institutions having total assets at the time of purchase in excess of $1 billion. These obligations may be general obligations of the parent bank or may be limited to the issuing branch or subsidiary by the terms of a specific obligation or by government regulation. The assets of a bank or savings institution will be deemed to include the assets of its domestic and foreign branches for purposes of the Fund's investment policies. Investments in short-term bank obligations may include obligations of foreign banks and domestic branches of foreign banks, and also foreign branches of domestic banks.

The Fund may purchase obligations of U.S. banks and savings and loan associations and dollar-denominated obligations of U.S. subsidiaries and branches of foreign banks, such as certificates of deposit (including marketable variable rate certificates of deposit) and bankers' acceptances. Bank certificates of deposit will only be acquired by the Fund if the bank has assets in excess of $1 billion.

The Fund may invest in debt obligations of domestic or foreign corporations and banks, and may acquire commercial obligations issued by Canadian corporations and Canadian counterparts of U.S. corporations, as well as Europaper, which is U.S. dollar-denominated commercial paper of a foreign issuer. The Fund may also make interest-bearing savings deposits in commercial and savings banks.

Guaranteed Investment Contracts. The Fund may make investments in guaranteed investment contracts ("GICs") issued by highly rated U.S. insurance companies. Under these contracts, the Fund makes cash contributions to a deposit fund of the insurance company's general account. The insurance company then credits to the Fund, on a monthly basis, interest which is based on an index, but is guaranteed not to be less than a certain minimum rate.

I-18

Interest Rate Transactions. The Fund may enter into interest rate swaps and the purchase or sale of interest rate caps and floors. The Fund expects to enter into these transactions primarily to preserve a return or spread on a particular investment or portion of its portfolio as a duration management technique or to protect against any increase in the price of securities the Fund anticipates purchasing at a later date. The Fund may enter into interest rate swaps, caps and floors on either an asset-based or liability-based basis.

The Fund intends to use these transactions for hedging and risk management purposes and not as a speculative investment. The Fund will not sell interest rate caps or floors that it does not own.

Futures Contracts and Options on Futures Contracts. In connection with its hedging and other risk management strategies, the Fund may also enter into contracts for the purchase or sale for future delivery ("future contracts") of debt securities, aggregates of debt securities, financial indices, and U.S. Government debt securities or options on the foregoing to hedge the value of its portfolio securities that might result from a change in interest rates or market movements. The Fund will engage in such transactions only for bona fide hedging, risk management and other appropriate portfolio management purposes.

The Fund may engage in options and futures transactions on exchanges and options in the over-the-counter markets ("OTC options"). The Fund will only enter into OTC options with counterparties the Investment Advisor believes to be creditworthy at the time they enter into such transactions.

The Commodity Futures Trading Commission ("CFTC") subjects advisers to registered investment companies to regulation by the CFTC if a fund that is advised by the investment adviser either (i) invests, directly or indirectly, more than a prescribed level of its liquidation value in CFTC-regulated futures, options and swaps ("CFTC Derivatives"), or (ii) markets itself as providing investment exposure to such instruments. To the extent the Fund uses CFTC Derivatives, it intends to do so below such prescribed levels and will not market itself as a "commodity pool" or a vehicle for trading such instruments. Accordingly, BlackRock Advisors, LLC has claimed an exclusion from the definition of the term "commodity pool operator" under the Commodity Exchange Act ("CEA") pursuant to Rule 4.5 under the CEA. BlackRock Advisors, LLC is not, therefore, subject to registration or regulation as a "commodity pool operator" under the CEA in respect of the Fund.

Calls on Securities, Indices and Futures Contracts. In order to enhance income or reduce fluctuations in NAV, the Fund may sell or purchase call options ("calls") on securities and indices based upon the prices of debt securities that are traded on U.S. securities exchanges and on the over-the-counter markets. All such calls sold by the Fund must be "covered" as long as the call is outstanding (i.e., the Fund must own the instrument subject to the call or other securities or assets acceptable for applicable earmarking and coverage requirements).

Puts on Securities, Indices and Futures Contracts. As with calls, the Fund may purchase put options ("puts") on securities (whether or not it holds such securities in its portfolio). For the same purposes, the Fund may also sell puts on securities financial indices and puts on futures contracts on securities if the Fund's contingent obligations on such puts are secured by designating cash or liquid assets on its books and records having a value not less than the exercise price. The Fund will not sell puts if, as a result, more than 50% of the Fund's assets would be required to cover its potential obligation under its hedging and other investment transactions.

Credit Default Swap Agreements and Credit Derivatives. The Fund may engage in credit derivative transactions. There are two broad categories of credit derivatives: default price risk derivatives and market spread derivatives. Default price risk derivatives are linked to the price of reference securities or loans after a default by the issuer or borrower, respectively. Market spread derivatives are based on the risk that changes in market factors, such as credit spreads, can cause a decline in the value of a security, loan or index. There are three basic transactional forms for credit derivatives: swaps, options and structured instruments.

In particular, the Fund may enter into credit default swap agreements. The credit default swap agreement may have as reference obligations one or more securities that are not currently held by the Fund. The protection "buyer" in a credit default contract may be obligated to pay the protection "seller" an upfront or a periodic stream of payments over the term of the contract provided that no credit event on a reference obligation has occurred. If a credit event occurs, the seller generally must pay the buyer the "par value" (full notional value) of the swap in exchange for an equal face amount of deliverable obligations of the reference entity described in the swap, or the seller may be

I-19

required to deliver the related net cash amount, if the swap is cash settled. The Fund may be either the buyer or seller in the transaction.

There is no limit on the amount of credit derivative transactions that may be entered into by the Fund.

Currency Forward Contacts. The Fund may purchase a forward currency contract to lock in the U.S. dollar price of a security denominated in a foreign currency that the Fund intends to acquire. The Fund may sell a forward currency contract to lock in the U.S. dollar equivalent of the proceeds from the anticipated sale of a security or a dividend or interest payment denominated in a foreign currency. The Fund may also use forward currency contracts to shift the Fund's exposure to foreign currency exchange rate changes from one currency to another. For example, if the Fund owns securities denominated in a foreign currency and the Investment Advisor believes that currency will decline relative to another currency, it might enter into a forward currency contract to sell the appropriate amount of the first foreign currency with payment to be made in the second currency. The Fund may also purchase forward currency contracts to enhance income when the Investment Advisor anticipates that the foreign currency will appreciate in value but securities denominated in that currency do not present attractive investment opportunities.

Swap Counterparties. The Fund may enter into swap transactions with any counterparties approved by the Investment Advisor. The Fund will seek to minimize its exposure to counterparty risk by entering into swap transactions with counterparties the Investment Advisor believes to be creditworthy at the time they enter into such transactions.

Short Sales. The Fund may make short sales of bonds. The Fund will not make a short sale if, after giving effect to such sale, the market value of all securities sold short exceeds 25% of the value of its Managed Assets or the Fund's aggregate short sales of a particular class of securities exceeds 25% of the outstanding securities of that class. The Fund may also make short sales "against the box" without respect to such limitations. In this type of short sale, at the time of the sale, the Fund owns or has the immediate and unconditional right to acquire at no additional cost the identical security.

Restricted and Illiquid Securities. The Fund may invest in illiquid securities, which are securities that lack a secondary trading market or are otherwise considered illiquid. When purchasing securities that have not been registered under the Securities Act, and are not readily marketable, the Fund will endeavor, to the extent practicable, to obtain the right to registration at the expense of the issuer.

The Fund may purchase certain securities eligible for resale to qualified institutional buyers as contemplated by Rule 144A under the Securities Act ("Rule 144A Securities"). Rule 144A provides an exemption from the registration requirements of the Securities Act for the resale of certain restricted securities to certain qualified institutional buyers. One effect of Rule 144A is that certain restricted securities may be considered liquid, though no assurance can be given that a liquid market for Rule 144A Securities will develop or be maintained. However, where a substantial market of qualified institutional buyers has developed for certain unregistered securities purchased by the Fund pursuant to Rule 144A under the Securities Act, the Fund intends to treat such securities as liquid securities in accordance with procedures approved by the Board. Because it is not possible to predict with assurance how the market for Rule 144A Securities will develop, the Board has directed the Investment Advisor to monitor carefully the Fund's investments in such securities with particular regard to trading activity, availability of reliable price information and other relevant information. To the extent that, for a period of time, qualified institutional buyers cease purchasing restricted securities pursuant to Rule 144A, the Fund's investing in such securities may have the effect of increasing the level of illiquidity in its investment portfolio during such period.

When-Issued and Forward Commitment Securities. The Fund may purchase securities on a "when-issued" basis and may purchase or sell securities on a "forward commitment" basis in order to acquire the security or to hedge against anticipated changes in interest rates and prices.

Rights Offerings and Warrants to Purchase. The Fund may participate in rights offerings and may purchase warrants, which are privileges issued by corporations enabling the owners to subscribe to and purchase a specified number of shares of the corporation at a specified price during a specified period of time.

Lending Securities. The Fund may lend securities with a value up to 33 1/3% of its Managed Assets to banks, brokers and other financial institutions.

I-20

Repurchase Agreements. As temporary investments, the Fund may invest in repurchase agreements. The Fund will only enter into repurchase agreements with registered securities dealers or domestic banks that, in the opinion of the Investment Advisor, present minimal credit risk.

Temporary Defensive Strategies. The Fund may implement various temporary "defensive" strategies at times when the Investment Advisor determines that conditions in the markets make pursuing the Fund's basic investment strategy inconsistent with the best interests of its shareholders. The Fund may not achieve its investment objective when it does so.

1940 Act and Tax Diversification Requirements. The Fund is classified as diversified within the meaning of the 1940 Act, which means that it is must satisfy the 5% and 10% requirements described in item (ii) below with respect to 75% of its total assets. The Fund's investments will be limited so as to qualify the Fund as a "regulated investment company" for purposes of Federal tax laws. Requirements for qualification as a "regulated investment company" include limiting its investments so that, at the close of each quarter of the taxable year, (i) not more than 25% of the market value of the Fund's total assets will be invested in (A) the securities of a single issuer (other than U.S. Government securities and securities of other regulated investment companies), (B) the securities of two or more issuers (other than securities of other regulated investment companies) controlled by the Fund and engaged in the same, similar or related trades or businesses, or (C) the securities of one or more qualified publicly traded partnerships, and (ii) with respect to 50% of the market value of its total assets, not more than 5% of the market value of its total assets will be invested in the securities of a single issuer and the Fund will not own more than 10% of the outstanding voting securities of a single issuer (other than U.S. Government securities and securities of other regulated investment companies).

Tax-related limitations may be changed by the Board to the extent appropriate in light of changes to applicable tax requirements.

Investment Process

In selecting securities for the Fund, BlackRock will seek to identify issuers and industries that BlackRock believes are likely to experience stable or improving financial conditions. BlackRock's analysis will include:

credit research on the issuers' financial strength;

assessment of the issuers' ability to meet principal and interest payments;

general industry trends;

the issuers' managerial strength;

changing financial conditions;

borrowing requirements or debt maturity schedules; and

the issuers' responsiveness to changes in business conditions and interest rates.

BlackRock will consider relative values among issuers based on anticipated cash flow, interest or dividend coverage, asset coverage and earnings prospects. Using these tools, BlackRock will seek to add consistent value and control performance volatility consistent with the Fund's investment objectives and policies. BlackRock believes this strategy should enhance the Fund's ability to achieve its investment objective. In managing the assets of the Fund, BlackRock will utilize an active management approach that stresses the flexibility to reallocate investments as appropriate. BlackRock will diversify the Fund's portfolio of assets in an effort to minimize exposure to individual securities, issuers and industries.

BlackRock's analysis continues on an ongoing basis for any securities in which the Fund has invested. Although BlackRock uses due care in making such analysis, there can be no assurance that such analysis will reveal factors that may impair the value of such securities.

Fundamental Investment Restrictions:

The following investment restrictions are considered fundamental by the Fund, which means that they may not be changed without the approval of the holders of a majority of the Fund's outstanding common shares (which for this purpose and under the 1940 Act means the lesser of (i) 67% of the common shares represented at a meeting at which

I-21

more than 50% of the outstanding common shares are represented, or (ii) more than 50% of the outstanding shares). Under the fundamental investment restrictions, the Fund may not:

(1)

purchase any security if as a result 25% or more of the total assets of the Fund would be invested in the securities of issuers having their principal business activities in the same industry (with respect to loan participations in which the Fund may invest, the Fund intends to treat as "issuers" the corporate borrower, the bank selling such participation interests and any other person interpositioned between the bank and the Fund);

(2)

with respect to 75% of its total assets, invest more than 5% of the value of its total assets in the securities of any single issuer or purchase more than 10% of the outstanding voting securities of any one issuer;

(3)

purchase commodities or commodity contracts, except that the Fund may purchase and sell options, futures contracts and options thereon and may engage in interest rate and foreign currency transactions

(4)

purchase, hold or deal in real estate or real estate mortgage loans, or oil, gas or other mineral leases or exploration or development programs, except that the Fund may (a) purchase and sell securities that are secured by, or issued by companies that invest or deal in, real estate, oil, gas or other minerals, or interests therein and (b) hold or sell any such assets acquired in connection with its investment in portfolio securities

(5)

issue senior securities or borrow money, except as permitted by the 1940 Act;

(6)

make loans to others, except through the purchase of debt obligations (including senior loans), the entry into repurchase agreements and the lending of its portfolio securities; and

(7)

act as an underwriter of securities of other issuers, except to the extent the Fund may be deemed an underwriter under the Securities Act, by virtue of its purchase or sale of portfolio securities.

For purposes of applying the limitation set forth in subparagraphs (1) and (2) above, securities of the U.S. Government, its agencies, or instrumentalities, and securities backed by the credit of a governmental entity are not considered to represent industries. However, obligations backed only by the assets and revenues of non-governmental issuers may for this purpose be deemed to be issued by such non-governmental issuers.

All other investment policies of the Fund are considered non-fundamental and may be changed by the Board without prior approval of the Fund's outstanding voting shares.

Non-Fundamental Investment Restrictions:

Any policies of the Fund not described as fundamental in this Prospectus may be changed by its Board without shareholder approval. Additional investment restrictions adopted by the Fund, which may be changed by the Board without shareholder approval, provide that the Fund may not:

(1)

make any short sale of securities except in conformity with applicable laws, rules and regulations and unless after giving effect to such sale, the market value of all securities sold short does not exceed 25% of the value of the Fund's Managed Assets and the Fund's aggregate short sales of a particular class of securities of an issuer does not exceed 25% of the then outstanding securities of that class. The Fund may also make short sales "against the box" without respect to such limitations. In this type of short sale, at the time of the sale, the Fund owns or has the immediate and unconditional right to acquire at no additional cost the identical security;

(2)

purchase securities of open-end or closed-end investment companies except in compliance with the 1940 Act or any exemptive relief obtained thereunder; or

I-22

(3)

purchase securities of companies for the purpose of exercising control.

Under the 1940 Act, the Fund may invest up to 10% of its Managed Assets in the aggregate in shares of other investment companies and up to 5% of its Managed Assets in any one investment company, provided the investment does not represent more than 3% of the voting stock of the acquired investment company at the time such shares are purchased.

Percentage and Rating Limitations:

All percentage and ratings limitations on securities in which the Fund may invest apply at the time of making an investment and shall not be considered violated if an investment rating is subsequently withdrawn or downgraded to a rating that would have precluded the Fund's initial investment in such security, or if exceeded as a result of market value fluctuations of the Fund's portfolio, and will not be considered violated unless an excess or deficiency occurs or exists immediately after and as a result of the acquisition of securities. In determining whether to retain or sell such a security, the Investment Advisor may consider such factors as its assessment of the credit quality of the issuer of the security, the price at which the security could be sold and the rating, if any, assigned to the security by other rating agencies. In the event that the Fund disposes of a portfolio security subsequent to its being downgraded, the Fund may experience a greater risk of loss than if such security had been sold prior to such downgrade.

All references to securities ratings by Moody's and S&P herein shall, unless otherwise indicated, include all securities within each such rating category (i.e., Ba1, Ba2 and Ba3 in the case of Moody's and BB+, BB and BB– in the case of S&P). For securities with split ratings (i.e., a security receiving two different ratings from two different rating agencies), the Fund will apply the higher of the applicable ratings.

Subsidiary:

The Fund wholly owns BLW Subsidiary, LLC, a Delaware-domiciled entity (the "Subsidiary"). The Subsidiary enables the Fund to hold investments that are organized as an operating partnership and satisfy regulated investment company ("RIC") tax requirements. Income earned and gains realized on the investments held by the Subsidiary are taxable to the Subsidiary. The Fund may invest up to 25% of its total assets in the Subsidiary. The Subsidiary's assets are managed by the Investment Advisor and are subject to the same investment policies and restrictions that apply to the Fund.

The Subsidiary is organized as a Delaware limited liability company and taxed as a corporation for Federal income tax purposes. The Subsidiary's limited liability company agreement provides that the business and affairs of the Subsidiary shall be managed by the Investment Advisor, as the manager of the Subsidiary within the meaning of the Delaware Limited Liability Company Act, subject to the supervision of the Board. The Investment Advisor does not receive separate compensation from the Subsidiary for providing investment management or administrative services. The Fund can remove the manager of the Subsidiary at any time. The Subsidiary does not make investments that Section 17 of the 1940 Act would prohibit the Fund or the Subsidiary from making. State Street Bank and Trust Company serves as the Subsidiary's custodian.

Additional Information:

Additional information regarding the foregoing securities, instruments and investment techniques are included in "Portfolio Contents and Techniques" under Item 8 in Part II.

3.a.

The risk factors associated with an investment in the Fund are set forth in "Risk Factors" under Item 8 in Part II. Due to the nature of the Fund's investment program, the Fund is particularly susceptible to the risks of fixed-income securities (such as interest rate risk and credit risk), high-yield and distressed securities, senior loans, mortgage-related securities, asset-backed securities, leveraging, illiquid securities, foreign investing, credit and other derivatives (such as options, credit default swaps and interest rate transactions), currency instruments and counterparty default.

I-23

3.b.	The Fund currently utilizes leverage for investment purposes in the form of reverse repurchase agreements. As of August 31, 2014, this leverage represented approximately 31% of the Fund's Managed Assets (approximately 44% of the Fund's net assets).

Assuming the utilization of leverage by borrowings in the amount of approximately 31% of the Fund's Managed Assets, and an annual interest rate of 0.49% payable on such leverage based on market rates as of the date of this Prospectus, the annual return that the Fund's portfolio must experience (net of expenses) in order to cover such interest payments would be 0.15%.

The following table is designed to illustrate the effect on the return to a holder of common shares of the leverage obtained by borrowings in the amount of approximately 31% of the Fund's Managed Assets, assuming hypothetical annual returns on the Fund's portfolio of minus 10% to plus 10%. As the table shows, leverage generally increases the return to shareholders when portfolio return is positive and greater than the cost of leverage and decreases the return when portfolio return is negative or less than the cost of leverage. The figures appearing in the table are hypothetical and actual returns may be greater or less than those appearing in the table.

Assumed Portfolio Return (net of expenses)		(10)%		(5)%		0%		5%		10%
Corresponding Common Share Return		(14.61)%		(7.41)%		(0.22)%		6.98%		14.18%

Common share total return is composed of two elements: the common share dividends paid by the Fund (the amount of which is largely determined by the net investment income of the Fund) and gains or losses on the value of the securities the Fund owns. As required by SEC rules, the table assumes that the Fund is more likely to suffer capital losses than to enjoy capital appreciation. For example, to assume a total return of 0% the Fund must assume that the interest it receives on its securities investments is entirely offset by losses in the value of those securities.

Additional information regarding the risks of the Fund's use of leverage is contained under "Item 8—Leverage" in Part II.

Item 9. Management

BlackRock Advisors, LLC acts as the investment adviser for the Fund. Pursuant to an investment management agreement between the Investment Advisor and the Fund (the "Investment Management Agreement"), the Fund pays the Investment Advisor a monthly fee at an annual rate of 0.55% of the Fund's average weekly Managed Assets (0.80% of the Fund's net assets, assuming leverage of approximately 30% of the Fund's Managed Assets). Because the management fee is calculated on the basis of Managed Assets, which includes assets attributable to leverage, the fee paid to the Investment Advisor will be higher than if the Fund did not use leverage.

BlackRock Financial Management, Inc., the Investment Advisor's affiliate, served as the sub-adviser for the Fund until July 1, 2014 when the sub-advisory agreement between the Investment Advisor and BlackRock Financial Management, Inc. expired.

A discussion regarding the basis for the approval of the Investment Management Agreement by the Board is available in the Fund's Annual Report to shareholders for the fiscal year ended August 31, 2014.

The Fund is managed by a team of investment professionals comprised of Leland Hart, Managing Director of BlackRock, James E. Keenan, Managing Director of BlackRock, C. Adrian Marshall, Managing Director of BlackRock, and Tom Musmanno, Managing Director of BlackRock, each of whom is jointly and primarily responsible for the day-to-day management of the Fund's portfolio.

The Board of the Fund currently consists of 11 individuals, nine of whom are not "interested persons" of the Fund as defined in the 1940 Act (the "Independent Trustees"). The registered investment companies advised by the Investment Advisor or its affiliates (the "BlackRock-Advised Funds") are organized into one complex of closed-end funds (the "Closed-End Complex"), two complexes of open-end funds (the "Equity-Liquidity Complex" and the "Equity-Bond Complex") and one complex of exchange-traded funds (the "Exchange-Traded Complex"; each such complex a "BlackRock Fund Complex"). The Fund is included in the Closed-End Complex. The Trustees also oversee as Board members the operations of the other closed-end registered investment companies included in the Closed-End Complex.

Information relating to each Trustee's share ownership in the Fund and in the other funds in the Closed-End Complex that are overseen by the respective Trustee as of December 31, 2013 is set forth in the chart below:

Item 20. Investment Advisory and Other Services

1.	The table below sets forth information about the total advisory fees, net of any applicable fee waiver, paid by the Fund to the Investment Advisor for the last three fiscal years.

	Year Ended August 31,
2014	2013	2012
$5,263,818(1)(2)	$5,261,885(1)(2)	$4,744,572(1)(2)

(1)

The Investment Advisor voluntarily agreed to waive its investment advisory fees by the amount of investment advisory fees the Fund pays to the Investment Advisor indirectly through its investment in affiliated money market funds. However, the Investment Advisor does not waive its investment advisory fees by the amount of investment advisory fees paid in connection with the Fund's investment in other affiliated investment companies, if any. Pursuant to this arrangement, the figures in the table above reflect waivers by the Investment Advisor of its fees in the amounts of $5,339, $5,075 and $2,198 for the years ended August 31, 2014, August 31, 2013 and August 31, 2012, respectively.

(2)

The Investment Advisor provides investment management and other services to the Subsidiary. The Investment Advisor does not receive separate compensation from the Subsidiary for providing investment management or administrative services. However, the Fund pays the Investment Advisor based on the Fund's net assets which includes the assets of the Subsidiary.

For the last three fiscal years, the Investment Advisor did not pay any sub-advisory fees to BlackRock Financial Management, Inc. BlackRock Financial Management, Inc., the Investment Advisor's affiliate, served as the sub-adviser for the Fund until July 1, 2014 when the sub-advisory agreement between the Investment Advisor and BlackRock Financial Management, Inc. expired.

Conflicts of Interest: Messrs. Hart, Keenan, Marshall, and Musmanno may be managing certain hedge fund and/or long only accounts, or may be part of a team managing certain hedge fund and/or long only accounts subject to incentive fees. Messrs. Hart, Keenan, Marshall, and Musmanno may therefore be entitled to receive a portion of any incentive fees earned on such accounts. See "Portfolio Managers — Potential Material Conflicts of Interest" under Item 21 in Part II.

I-31

See Item 21 in Part II for a general overview and description of the structure of, and the method used to determine, the compensation of the portfolio managers. The principal components of compensation include a base salary, a performance-based discretionary bonus, participation in various benefits programs and one or more of the incentive compensation programs established by BlackRock. The following sets forth how various components of this compensation structure apply specifically to these portfolio managers as of August 31, 2014.

Performance-Based Discretionary Bonus. Among other things, BlackRock's Chief Investment Officers make a subjective determination with respect to each portfolio manager's compensation based on the performance of the funds and other accounts managed by each portfolio manager relative to the various benchmarks. Performance of fixed income funds is measured on a pre-tax and/or after-tax basis over various time periods including 1-, 3- and 5- year periods, as applicable. With respect to Leland Hard and C. Adrian Marshall, such benchmarks for the Fund and other accounts are a combination of market-based indices (e.g., S&P Leveraged All Loan Index), certain customized indices and certain fund industry peer groups. With respect to James E. Keenan, such benchmarks for the Fund and other accounts are a combination of market-based indices (e.g., The Barclays U.S. Corporate High Yield 2% Issuer Cap Index), certain customized indices and certain fund industry peer groups. With respect to Thomas Musmanno, such benchmarks for the Fund and other accounts are a combination of market-based indices (e.g., Bank of America Merrill Lynch U.S. Corporate & Government Index, 1-3 Years), certain customized indices and certain fund industry peer groups.

Long-Term Incentive Plan Awards. These portfolio managers have unvested long-term incentive awards.

Deferred Compensation Program. Any portfolio manager who is either a managing director or director at BlackRock (which would include these portfolio managers) is eligible to participate in the deferred compensation program.

Incentive Savings Plan. All of the eligible portfolio managers are eligible to participate in these plans.

3.	As of August 31, 2014, the portfolio managers beneficially own the following dollar ranges of equity securities in the Fund:

Portfolio Manager		Dollar Range of Equity Securities of the Fund Beneficially Owned
Leland Hart		None
James E. Keenan		None
C. Adrian Marshall		None
Thomas Musmanno		None

See Item 22 in Part II for additional information about how the Fund effects portfolio transactions.

The Investment Advisor may place portfolio transactions, to the extent permitted by law, with brokerage firms affiliated with the Fund and the Investment Advisor, if it reasonably believes that the quality of execution and the commission are comparable to that available from other qualified brokerage firms.

The Fund has not paid any brokerage commissions to affiliated broker-dealers during the three most recent fiscal years.

ADDITIONAL INFORMATION ABOUT

BLACKROCK LIMITED DURATION INCOME TRUST

Item 5. Plan of Distribution

The Fund has entered into a Distribution Agreement (the "Distribution Agreement") with BlackRock Investments, LLC, an affiliate of the Fund and the Investment Advisor located at 55 East 52nd Street, New York, NY 10055, to provide for distribution of the Fund's common shares on a reasonable efforts basis through various specified transactions, including at-the-market offerings pursuant to Rule 415 under the Securities Act, subject to various conditions. The Distribution Agreement has been filed as an exhibit to the Registration Statement of which this Prospectus is a part. The summary of the Distribution Agreement contained herein is qualified by reference to the Distribution Agreement.

Subject to the terms and conditions of the Distribution Agreement, the Fund may from time to time issue and sell its common shares through the Distributor to certain broker-dealers which have entered into selected sub-placement agent agreements with the Distributor. Currently, the Distributor has entered into a sub-placement agent agreement with UBS Securities LLC, pursuant to which the Dealer will be acting as the Distributor's sub-placement agent with respect to at-the-market offerings of the Fund's common shares. The Dealer Agreement has been filed as an exhibit to the Registration Statement of which this Prospectus forms a part. The summary of the Dealer Agreement contained herein is qualified by reference to the Dealer Agreement.

Under the Dealer Agreement, upon instructions from the Distributor the Dealer will use its reasonable best efforts to sell, as sub-placement agent, Fund common shares under the terms and subject to the conditions set forth in the Dealer Agreement. The Distributor will instruct the Dealer as to the amount of Fund common shares authorized for sale by the Dealer on any particular day that is a trading day for the exchange on which the Fund's common shares are listed and primarily trade. The Distributor will also instruct the Dealer not to sell Fund common shares if the sales cannot be effected at or above a price designed by the Distributor, which price will at least be equal to the Minimum Price and which price, may, in the discretion of the Distributor and the Fund, be above the Minimum Price. The Distributor and the Fund may, in their discretion, determine not to authorize sales of the Fund's common shares on a particular day even if the per share price of the shares is equal to or greater than the Minimum Price. The Fund and the Distributor will have full discretion regarding whether sales of Fund common shares will be authorized on a particular day and, if so, in what amounts. The Fund, the Distributor or the Dealer may suspend a previously authorized offering of Fund common shares upon proper notice and subject to other conditions.

The Dealer will provide written confirmation to the Distributor following the close of trading on a day on which Fund common shares are sold under the Dealer Agreement. Each confirmation will include the number of shares sold, the net proceeds to the Fund and the compensation that the Dealer is owed in connection with the sales. There is no guarantee that there will be any sales of the Fund's common shares pursuant to this Prospectus. Actual sales, if any, of the Fund's common shares may be greater or less than the most recent market price set forth in this Prospectus, depending on the market price of the Fund's common shares at the time of any such sale; provided, however, that sales will not be made at less than the Minimum Price.

Settlements of sales of common shares will occur on the third business day following the date on which any such sales are made.

In connection with the sale of common shares on behalf of the Fund, the Distributor may be deemed to be an underwriter within the meaning of the Securities Act, and the compensation of the Distributor may be deemed to be underwriting commissions or discounts.

The offering of the Fund's common shares pursuant to the Distribution Agreement will terminate upon the earlier of (i) the sale of all common shares subject thereto or (ii) termination of the Distribution Agreement. The Fund and the Distributor each have the right to terminate the Distribution Agreement in its discretion upon advance notice to the other party.

II-1

The Dealer, its affiliates and their respective employees hold or may hold in the future, directly or indirectly, investment interests in BlackRock, Inc., the parent company of the Distributor, and funds advised by the Investment Advisor and its affiliates. The interests held by employees of the Dealer or its affiliates are not attributable to, and no investment discretion is held by, the Dealer or its affiliates.

The Fund has agreed to indemnify the Distributor and hold the Distributor harmless against certain liabilities, including certain liabilities under the Securities Act, except for any liability to the Fund or its investors to which the Distributor would otherwise be subject by reason of willful misfeasance, bad faith or gross negligence in the performance of its duties or by its reckless disregard of its obligations and duties under its agreement with the Fund.

Additional information regarding the plan of distribution is set forth under Item 5 in Part I.

Item 8. Description of the Fund

Portfolio Contents and Techniques

The Fund may invest in the following instruments and use the following investment techniques, subject to any limitations set forth in Part I. There is no guarantee the Fund will buy all of the types of securities or use all of the investment techniques that are described herein.

Corporate Bonds. Corporate bonds are debt obligations issued by corporations. Corporate bonds may be either secured or unsecured. Collateral used for secured debt includes real property, machinery, equipment, accounts receivable, stocks, bonds or notes. If a bond is unsecured, it is known as a debenture. Bondholders, as creditors, have a prior legal claim over common and preferred stockholders as to both income and assets of the corporation for the principal and interest due them and may have a prior claim over other creditors if liens or mortgages are involved. Interest on corporate bonds may be fixed or floating, or the bonds may be zero coupons. Interest on corporate bonds is typically paid semi-annually and is fully taxable to the bondholder. Corporate bonds contain elements of both interest rate risk and credit risk. The market value of a corporate bond generally may be expected to rise and fall inversely with interest rates and may also be affected by the credit rating of the corporation, the corporation's performance and perceptions of the corporation in the marketplace. Corporate bonds usually yield more than government or agency bonds due to the presence of credit risk.

High Yield Securities. The Fund may invest in securities rated, at the time of investment, below investment grade quality such as those rated Ba or below by Moody's or BB or below by S&P, or securities comparably rated by other rating agencies or in unrated securities determined by the Investment Advisor to be of comparable quality. Such securities, sometimes referred to as "high yield" or "junk" bonds, are predominantly speculative with respect to the capacity to pay interest and repay principal in accordance with the terms of the security and generally involve greater price volatility than securities in higher rating categories. Often the protection of interest and principal payments with respect to such securities may be very moderate and issuers of such securities face major ongoing uncertainties or exposure to adverse business, financial or economic conditions which could lead to inadequate capacity to meet timely interest and principal payments.

Lower grade securities, though high yielding, are characterized by high risk. They may be subject to certain risks with respect to the issuing entity and to greater market fluctuations than certain lower yielding, higher rated securities. The secondary market for lower grade securities may be less liquid than that of higher rated securities. Adverse conditions could make it difficult at times for the Fund to sell certain securities or could result in lower prices than those used in calculating the Fund's NAV.

The prices of fixed income securities generally are inversely related to interest rate changes; however, the price volatility caused by fluctuating interest rates of securities also is inversely related to the coupons of such securities. Accordingly, below investment grade securities may be relatively less sensitive to interest rate changes than higher quality securities of comparable maturity because of their higher coupon. The investor receives this higher coupon in return for bearing greater credit risk. The higher credit risk associated with below investment grade securities potentially can have a greater effect on the value of such securities than may be the case with higher quality issues of comparable maturity.

II-2

Lower grade securities may be particularly susceptible to economic downturns. It is likely that an economic recession could severely disrupt the market for such securities and may have an adverse impact on the value of such securities. In addition, it is likely that any such economic downturn could adversely affect the ability of the issuers of such securities to repay principal and pay interest thereon and increase the incidence of default for such securities.

The ratings of Moody's, S&P and other rating agencies represent their opinions as to the quality of the obligations which they undertake to rate. Ratings are relative and subjective and, although ratings may be useful in evaluating the safety of interest and principal payments, they do not evaluate the market value risk of such obligations. Although these ratings may be an initial criterion for selection of portfolio investments, the Investment Advisor also will independently evaluate these securities and the ability of the issuers of such securities to pay interest and principal. To the extent that the Fund invests in lower grade securities that have not been rated by a rating agency, the Fund's ability to achieve its investment objective will be more dependent on the Investment Advisor's credit analysis than would be the case when the Fund invests in rated securities.

Distressed and Defaulted Securities. The Fund may invest in securities of financially distressed and bankrupt issuers, including debt obligations that are in covenant or payment default. Such investments generally trade significantly below par and are considered speculative. The repayment of defaulted obligations is subject to significant uncertainties. Defaulted obligations might be repaid only after lengthy workout or bankruptcy proceedings, during which the issuer might not make any interest or other payments. Typically such workout or bankruptcy proceedings result in only partial recovery of cash payments or an exchange of the defaulted obligation for other debt or equity securities of the issuer or its affiliates, which may in turn be illiquid or speculative.

Senior Loans. The senior loans in which the Fund invests may consist of direct obligations of a borrower undertaken to finance the growth of the borrower's business, internally or externally, or to finance a capital restructuring. Senior loans may also include debtor in possession financings pursuant to Chapter 11 of the U.S. Bankruptcy Code and obligations of a borrower issued in connection with a restructuring pursuant to Chapter 11 of the U.S. Bankruptcy Code. A significant portion of such senior loans are highly leveraged loans such as leveraged buy-out loans, leveraged recapitalization loans and other types of acquisition loans. Such senior loans may be structured to include both term loans, which are generally fully funded at the time of the Fund's investment, and revolving credit facilities or delayed draw term loans, which would require the Fund to make additional investments in the senior loans as required under the terms of the credit facility. Such senior loans may also include receivables purchase facilities, which are similar to revolving credit facilities secured by a borrower's receivables, senior loans designed to provide "bridge" financing to a borrower pending the sale of identified assets or the arrangement of longer-term loans or the issuance and sale of debt obligations or senior loans of borrowers that have obtained bridge loans from other parties. Senior loans generally are issued in the form of senior syndicated loans, but the Fund also may invest from time to time in privately placed notes, credit linked notes, structured notes or other instruments with credit and pricing terms which are, in the opinion of the Investment Advisor, consistent with investments in senior loan obligations.

The senior loans in which the Fund invests typically have stated maturities ranging from five to nine years, though such stated maturities could vary from this range and the Fund is not subject to any restrictions with respect to the maturity of senior loans held in its portfolio. As a result, as short-term interest rates increase, interest payable to the Fund from its investments in senior loans should increase, and as short-term interest rates decrease, interest payable to the Fund from its investments in senior loans should decrease. Because of prepayments, the Investment Advisor expects the average life of the senior loans in which the Fund invests to be shorter than the stated maturity.

The senior loans in which the Fund invests generally hold a senior position in the capital structure of the borrower. Such loans may include loans that hold the most senior position, loans that hold an equal ranking with other senior debt, or loans that are, in the judgment of the Investment Advisor, in the category of senior debt. A senior position in the borrower's capital structure generally gives the holder of the senior loan a claim on some or all of the borrower's assets that is senior to that of subordinated debt, preferred stock and common stock in the event the borrower defaults or becomes bankrupt. The senior loans in which the Fund invests may be wholly or partially secured by collateral, or may be unsecured. In the event of a default, the ability of an investor to have access to any collateral may be limited by bankruptcy and other insolvency laws. The value of the collateral also may decline subsequent to the Fund's investment in the senior loan. Under certain circumstances, the collateral may be released with the consent of the Agent Bank and Co-Lenders (each as defined below), or pursuant to the terms of the underlying credit agreement with the borrower. There is no assurance that the liquidation of the collateral will

II-3

satisfy the borrower's obligation in the event of nonpayment of scheduled interest or principal, or that the collateral could be readily liquidated. As a result, the Fund might not receive payments to which it is entitled and thereby may experience a decline in the value of the investment, and possibly, its NAV.

In the case of highly leveraged senior loans, a borrower is often required to pledge collateral that may include (i) working capital assets, such as accounts receivable and inventory, (ii) tangible fixed assets, such as real property, buildings and equipment, (iii) intangible assets, such as trademarks, copyrights and patent rights and/or (iv) security interests in securities of subsidiaries or affiliates. Collateral also may include guarantees or other credit support by subsidiaries or affiliates. In some cases the only collateral for the senior loan is the stock of the borrower and/or its subsidiaries and affiliates. To the extent a senior loan is secured by stock of the borrower and/or its subsidiaries and affiliates, such stock may lose all of its value in the event of a bankruptcy or insolvency of the borrower. In the case of senior loans to privately held companies, the companies' owners may provide additional credit support in the form of guarantees and/or pledges of other securities that they own.

In the case of project finance loans, the borrower is generally a special purpose entity that pledges undeveloped land and other non-income producing assets as collateral and obtains construction completion guaranties from third parties, such as the project sponsor. Project finance credit facilities typically provide for payment of interest from escrowed funds during a scheduled construction period, and for the pledge of current and fixed assets after the project is constructed and becomes operational. During the construction period, however, the lenders bear the risk that the project will not be constructed in a timely manner, or will exhaust project funds prior to completion. In such an event, the lenders may need to take legal action to enforce the completion guaranties, or may need to lend more money to the project on less favorable financing terms, or may need to liquidate the undeveloped project assets. There can be no assurance in any of such cases that the lenders will recover all of their invested capital.

The rate of interest payable on senior floating rate loans is established as the sum of a base lending rate plus a specified margin. These base lending rates generally are the prime rate ("Prime Rate") of a designated U.S. bank, London Interbank Offered Rate ("LIBOR"), the Certificate of Deposit ("CD") rate or another base lending rate used by commercial lenders. The interest rate on Prime Rate-based senior loans floats daily as the Prime Rate changes, while the interest rate on LIBOR-based and CD-based senior loans is reset periodically, typically every one, two, three or six months. Certain of the senior floating rate loans in which the Fund invests permit the borrower to select an interest rate reset period of up to one year. A portion of the Fund's portfolio may be invested in senior loans with interest rates that are fixed for the term of the loan. Investment in senior loans with longer interest rate reset periods or fixed interest rates may increase fluctuations in the Fund's NAV, and potentially the market price of the Fund's common shares, as a result of changes in interest rates.

The Fund may receive and/or pay certain fees in connection with its lending activities. These fees are in addition to interest payments received and may include facility fees, commitment fees, amendment and waiver fees, commissions and prepayment fees. In certain circumstances, the Fund may receive a prepayment fee on the prepayment of a senior loan by a borrower. In connection with the acquisition of senior loans or other debt securities, the Fund also may acquire warrants and other debt and equity securities of the borrower or issuer or its affiliates. The Fund may also acquire other debt and equity securities of the borrower or issuer in connection with an amendment, waiver, conversion or exchange of a senior loan or in connection with a bankruptcy or workout of the borrower or issuer.

In making an investment in a senior loan, the Investment Advisor will consider factors deemed by it to be appropriate to the analysis of the borrower and the senior loan. The Investment Advisor performs its own independent credit analysis of the borrower in addition to utilizing information prepared and supplied by the Agent Bank, Co-Lender or Participant (each defined below) from whom the Fund purchases its interest in a senior loan. Such factors include, but are not limited to, the legal/protective features associated with the securities (such as their position in the borrower's capital structure and any security through collateral), financial ratios of the borrower such as pre-tax interest coverage, leverage ratios, and the ratios of cash flows to total debts and the ratio of tangible assets to debt. In its analysis of these factors, the Investment Advisor also will be influenced by the nature of the industry in which the borrower is engaged, the nature of the borrower's assets and the Investment Advisor's assessments of the general quality of the borrower. The Investment Advisor's analysis continues on an ongoing basis for any senior loans in which the Fund has invested. Although the Investment Advisor uses due care in making such analysis, there can be no assurance that such analysis will disclose factors that may impair the value of the senior loan.

II-4

Senior loans made in connection with highly leveraged transactions are subject to greater credit risks than other senior loans in which each Fund may invest. These credit risks include a greater possibility of default or bankruptcy of the borrower and the assertion that the pledging of collateral to secure the loan constituted a fraudulent conveyance or preferential transfer which can be nullified or subordinated to the rights of other creditors of the borrower under applicable law.

Many senior loans in which the Fund invests may not be rated by a rating agency, are not registered with the SEC, or any state securities commission, and are not listed on any national securities exchange. Borrowers may have outstanding debt obligations that are rated below investment grade by a rating agency. Many of the senior loans in which the Fund invests will have been assigned below investment grade ratings by independent rating agencies. In the event senior loans are not rated, they are likely to be the equivalent of below investment grade quality. The Investment Advisor does not view ratings as the determinative factor in its investment decisions and relies more upon its credit analysis abilities than upon ratings.

The Fund has no policy with regard to minimum ratings for senior loans in which it may invest. The Fund may purchase and retain in its portfolio senior loans where the borrower has experienced, or may be perceived to be likely to experience, credit problems, including involvement in or recent emergence from bankruptcy reorganization proceedings or other forms of debt restructuring. Such investments may provide opportunities for enhanced income as well as capital appreciation, although they also will be subject to greater risk of loss. At times, in connection with the restructuring of a senior loan either outside of bankruptcy court or in the context of bankruptcy court proceedings, the Fund may determine or be required to accept equity securities or junior fixed income securities in exchange for all or a portion of a senior loan.

The secondary market for trading of senior loans continues to develop and mature. One of the effects of a more active and liquid secondary market, however, is that a senior loan may trade at a premium or discount to the principal amount, or par value, of the loan. There are many factors that influence the market value of a senior loan, including technical factors relating to the operation of the loan market, supply and demand conditions, market perceptions about the credit quality or financial condition of the borrower or more general concerns about the industry in which the borrower operates. The Fund participates in this secondary market for senior loans, purchasing and selling loans that may trade at a premium or discount to the par value of the loan. However, no active trading market may exist for some senior loans and some loans may be subject to restrictions on resale. A secondary market may be subject to irregular trading activity, wide bid/ask spreads and extended trade settlement periods, which may impair the ability to realize full value and thus cause a material decline in the Fund's NAV. In addition, the Fund may not be able to readily dispose of its senior loans at prices that approximate those at which the Fund could sell such loans if they were more widely-traded and, as a result of such illiquidity, the Fund may have to sell other investments or engage in borrowing transactions if necessary to raise cash to meet its obligations. During periods of limited supply and liquidity of senior loans, the Fund's yield may be lower.

When interest rates decline, the value of a fund invested in fixed rate obligations can be expected to rise. Conversely, when interest rates rise, the value of a fund invested in fixed rate obligations can be expected to decline. Although changes in prevailing interest rates can be expected to cause some fluctuations in the value of floating rate senior loans (due to the fact that floating rates on senior loans only reset periodically), the value of floating rate senior loans is substantially less sensitive to changes in market interest rates than fixed rate instruments. As a result, to the extent the Fund invests in floating rate senior loans, the Fund's portfolio may be less volatile and less sensitive to changes in market interest rates than if the Fund invested in fixed rate obligations. Similarly, a sudden and significant increase in market interest rates may cause a decline in the value of these investments and in the Fund's NAV. Other factors (including, but not limited to, rating downgrades, credit deterioration, a large downward movement in stock prices, a disparity in supply and demand of certain securities or market conditions that reduce liquidity) can reduce the value of senior loans and other debt obligations, impairing the Fund's NAV.

A borrower must comply with various restrictive covenants contained in any credit agreement between the borrower and the lending syndicate. Such covenants, in addition to requiring the scheduled payment of interest and principal, may include restrictions on dividend payments and other distributions to stockholders, provisions requiring the borrower to maintain specific financial ratios or relationships, limits on total debt and restrictions on the borrower's ability to pledge its assets. In addition, the loan agreement may contain a covenant requiring the borrower to prepay the senior loan with any excess cash flow. Excess cash flow generally includes net cash flow after scheduled debt service payments and permitted capital expenditures, among other things, as well as the

II-5

proceeds from asset dispositions or sales of securities. A breach of a covenant (after giving effect to any cure period) which is not waived by the Agent Bank and the lending syndicate normally is an event of default (i.e., the Agent Bank has the right to call the outstanding senior loan).

Senior loans usually require, in addition to scheduled payments of interest and principal, the prepayment of the senior loan from excess cash flow, as discussed above, and typically permit the borrower to prepay at its election. The degree to which borrowers prepay senior loans, whether as a contractual requirement or at their election, may be affected by general business conditions, the financial condition of the borrower and competitive conditions among lenders, among other factors. Accordingly, prepayments cannot be predicted with accuracy. Upon a prepayment, the Fund may receive both a prepayment fee from the prepaying borrower and a facility fee on the purchase of a new senior loan with the proceeds from the prepayment of the former. Such fees may mitigate any adverse impact on the yield on the Fund's portfolio which may arise as a result of prepayments and the reinvestment of such proceeds in senior loans bearing lower interest rates.

A senior loan in which the Fund may invest typically is originated, negotiated and structured by a syndicate of lenders ("Co-Lenders") consisting of commercial banks, thrift institutions, insurance companies, finance companies, investment banking firms, securities brokerage houses or other financial institutions or institutional investors, one or more of which administers the loan on behalf of the syndicate (the "Agent Bank"). Co-Lenders may sell senior loans to third parties ("Participants"). The Fund invests in a senior loan either by participating in the primary distribution as a Co-Lender at the time the loan is originated or by buying an assignment or participation interest in the senior loan in the secondary market from a Co-Lender or a Participant.

The Fund may invest in a senior loan at origination as a Co-Lender or by acquiring an assignment or participation interest in the secondary market from a Co-Lender or Participant. If the Fund purchases an assignment, the Fund typically accepts all of the rights of the assigning lender in a senior loan, including the right to receive payments of principal and interest and other amounts directly from the borrower and to enforce its rights as a lender directly against the borrower and assumes all of the obligations of the assigning lender, including any obligations to make future advances to the borrower. As a result, therefore, the Fund has the status of a Co-Lender. In some cases, the rights and obligations acquired by a purchaser of an assignment may differ from, and may be more limited than, the rights and obligations of the assigning lender. The Fund also may purchase a participation in a portion of the rights of a Co-Lender or Participant in a senior loan by means of a participation agreement. A participation is similar to an assignment in that the Co-Lender or Participant transfers to the Fund all or a portion of an interest in a senior loan. Unlike an assignment, however, a participation does not establish any direct relationship between the Fund and the borrower. In such a case, the Fund is required to rely on the Co-Lender or Participant that sold the participation not only for the enforcement of the Fund's rights against the borrower but also for the receipt and processing of payments due to the Fund under the senior loans.

Because it may be necessary to assert through a Co-Lender or Participant such rights as may exist against the borrower, in the event the borrower fails to pay principal and interest when due, the Fund may be subject to delays, expenses and risks that are greater than those that would be involved if the Fund could enforce its rights directly against the borrower. Moreover, under the terms of a participation, the Fund may be regarded as a creditor of the Co-Lender or Participant that sold the participation (rather than of the borrower), so that the Fund may also be subject to the risk that the Co-Lender or Participant may become insolvent. Similar risks may arise with respect to the Agent Bank, as described below. Further, in the event of the bankruptcy or insolvency of the borrower, the obligation of the borrower to repay the senior loan may be subject to certain defenses that can be asserted by such borrower as a result of improper conduct by the Agent Bank, Co-Lender or Participant.

In a typical senior loan, the Agent Bank administers the terms of the credit agreement and is responsible for the collection of principal and interest and fee payments from the borrower and the apportionment of these payments to the credit of all lenders which are parties to the credit agreement. The Fund generally relies on the Agent Bank (or the Co-Lender or Participant that sold the Fund a participation interest) to collect its portion of the payments on the senior loan. Furthermore, the Fund generally relies on the Agent Bank to use appropriate creditor remedies against the borrower. Typically, under credit agreements, the Agent Bank is given broad discretion in enforcing the credit agreement, and is obligated to use only the same care it would use in the management of its own property. The borrower compensates the Agent Bank for these services. Such compensation may include special fees paid on structuring and funding the senior loan and other fees paid on a continuing basis.

II-6

In the event that an Agent Bank becomes insolvent, or has a receiver, conservator, or similar official appointed for it by the appropriate bank regulatory authority or becomes a debtor in a bankruptcy proceeding, assets held by the Agent Bank under the credit agreement should remain available to holders of senior loans.

If, however, assets held by the Agent Bank for the benefit of the Fund were determined by an appropriate regulatory authority or court to be subject to the claims of the Agent Bank's general or secured creditors, the Fund might incur certain costs and delays in realizing payment on a senior loan or suffer a loss of principal and/or interest. In situations involving a Co-Lender or Participant that sold the Fund a participation interest, similar risks may arise, as described above.

The Fund may have certain obligations pursuant to a credit agreement, which may include the obligation to make future advances to the borrower in connection with revolving credit facilities in certain circumstances. These commitments may have the effect of requiring the Fund to increase its investment in a borrower at a time it might not be desirable to do so (including at a time when the borrower's financial condition makes it unlikely that such amounts will be repaid). The Fund currently intends to reserve against such contingent obligations by designating sufficient investments in liquid assets on its books and records.

The Fund may obtain exposure to senior loans through the use of derivative instruments, which have recently become increasingly available. The Investment Advisor may utilize these instruments and similar instruments that may be available in the future. The Fund may invest in a derivative instrument known as a Select Aggregate Market Index ("SAMI"), which provides investors with exposure to a reference basket of senior loans. SAMIs are structured as floating rate instruments. SAMIs consist of a basket of credit default swaps whose underlying reference securities are senior secured loans. While investing in SAMIs will increase the universe of floating rate fixed income securities to which the Fund is exposed, such investments entail risks that are not typically associated with investments in other floating rate fixed income securities. The liquidity of the market for SAMIs will be subject to liquidity in the secured loan and credit derivatives markets. Investment in SAMIs involves many of the risks associated with investments in derivative instruments discussed generally herein.

Second Lien Loans. The Fund may invest in second lien or other subordinated or unsecured floating rate and fixed rate loans or debt. Second lien loans have the same characteristics as senior loans except that such loans are second in lien property rather than first. Second lien loans typically have adjustable floating rate interest payments. Accordingly, the risks associated with second lien loans are higher than the risk of loans with first priority over the collateral. In the event of default on a second lien loan, the first priority lien holder has first claim to the underlying collateral of the loan. It is possible that no collateral value would remain for the second priority lien holder, which may result in a loss of investment to the Fund.

Mezzanine Loans. The Fund may invest in mezzanine loans. Structurally, mezzanine loans usually rank subordinate in priority of payment to senior debt, such as senior bank debt, and are often unsecured. However, mezzanine loans rank senior to common and preferred equity in a borrower's capital structure. Mezzanine debt is often used in leveraged buyout and real estate finance transactions. Typically, mezzanine loans have elements of both debt and equity instruments, offering the fixed returns in the form of interest payments associated with senior debt, while providing lenders an opportunity to participate in the capital appreciation of a borrower, if any, through an equity interest. This equity interest typically takes the form of warrants. Due to their higher risk profile and often less restrictive covenants as compared to senior loans, mezzanine loans generally earn a higher return than senior secured loans. The warrants associated with mezzanine loans are typically detachable, which allows lenders to receive repayment of their principal on an agreed amortization schedule while retaining their equity interest in the borrower. Mezzanine loans also may include a "put" feature, which permits the holder to sell its equity interest back to the borrower at a price determined through an agreed-upon formula. Mezzanine investments may be issued with or without registration rights. Similar to other high yield securities, maturities of mezzanine investments are typically seven to ten years, but the expected average life is significantly shorter at three to five years; however, maturities and expected average lives could vary from these ranges and the Fund is not subject to any restrictions with respect to the maturities or expected average lives of mezzanine loans held in its portfolio. Mezzanine investments are usually unsecured and subordinate to other obligations of the issuer.

Debtor-In-Possession Financings. The Fund may invest in "debtor-in-possession" or "DIP" financings newly issued in connection with "special situation" restructuring and refinancing transactions. DIP financings are loans to a debtor-in-possession in a proceeding under the U.S. Bankruptcy Code that has been approved by the

II-7

bankruptcy court. These financings allow the entity to continue its business operations while reorganizing under Chapter 11 of the U.S. Bankruptcy Code. DIP financings are typically fully secured by a lien on the debtor's otherwise unencumbered assets or secured by a junior lien on the debtor's encumbered assets (so long as the loan is fully secured based on the most recent current valuation or appraisal report of the debtor). DIP financings are often required to close with certainty and in a rapid manner in order to satisfy existing creditors and to enable the issuer to emerge from bankruptcy or to avoid a bankruptcy proceeding.

Mortgage Related Securities. Mortgage-backed securities ("MBS") include structured debt obligations collateralized by pools of commercial ("CMBS") or residential ("RMBS") mortgages. Pools of mortgage loans and mortgage-backed loans, such as mezzanine loans, are assembled as securities for sale to investors by various governmental, government-related and private organizations. MBS include complex instruments such as collateralized mortgage obligations ("CMOs"), stripped MBS, mortgage pass-through securities and interests in Real Estate Mortgage Investment Conduits ("REMICs"). The MBS in which the Fund may invest include those with fixed, floating or variable interest rates, those with interest rates that change based on multiples of changes in a specified reference interest rate or index of interest rates and those with interest rates that change inversely to changes in interest rates, as well as those that do not bear interest. The Fund may invest in RMBS and CMBS issued by governmental entities and private issuers, including subordinated MBS and residual interests. The Fund may invest in sub-prime mortgages or MBS that are backed by sub-prime mortgages.

In general, losses on a mortgaged property securing a mortgage loan included in a securitization will be borne first by the equity holder of the property, then by a cash reserve fund or letter of credit, if any, then by the holder of a mezzanine loan or B-Note, if any, then by the "first loss" subordinated security holder (generally, the "B-Piece" buyer) and then by the holder of a higher rated security. The Fund may invest in any class of security included in a securitization. In the event of default and the exhaustion of any equity support, reserve fund, letter of credit, mezzanine loans or B-Notes, and any classes of securities junior to those in which the Fund invests, the Fund will not be able to recover all of its investment in the MBS it purchases. MBS in which the Fund invests may not contain reserve funds, letters of credit, mezzanine loans and/or junior classes of securities. The prices of lower credit quality securities are generally less sensitive to interest rate changes than more highly rated investments, but more sensitive to adverse economic downturns or individual issuer developments.

Mortgage Pass-Through Securities. Mortgage pass-through securities differ from other forms of fixed income securities, which normally provide for periodic payment of interest in fixed amounts with principal payments at maturity or specified call dates. Instead, these securities provide a monthly payment which consists of both interest and principal payments. In effect, these payments are a "pass through" of the monthly payments made by the individual borrowers on their residential or commercial mortgage loans, net of any fees paid to the issuer or guarantor of such securities. Additional payments are caused by repayments of principal resulting from the sale of the underlying property, refinancing or foreclosure, net of fees or costs that may be incurred. Some mortgage related securities (such as securities issued by the Government National Mortgage Association ("GNMA")) are described as "modified pass-through." These securities entitle the holder to receive all interest and principal payments owed on the mortgage pool, net of certain fees, at the scheduled payment dates regardless of whether or not the mortgagor actually makes the payment.

RMBS. RMBS are securities the payments on which depend primarily on the cash flow from residential mortgage loans made to borrowers that are secured, on a first priority basis or second priority basis, subject to permitted liens, easements and other encumbrances, by residential real estate (one- to four-family properties), the proceeds of which are used to purchase real estate and purchase or construct dwellings thereon or to refinance indebtedness previously used for such purposes. Non-agency residential mortgage loans are obligations of the borrowers thereunder only and are not typically insured or guaranteed by any other person or entity. The ability of a borrower to repay a loan secured by residential property is dependent upon the income or assets of the borrower. A number of factors, including a general economic downturn, acts of God, terrorism, social unrest and civil disturbances, may impair a borrower's ability to repay its loans.

Agency RMBS. The principal U.S. Governmental guarantor of mortgage related securities is GNMA, which is a wholly owned U.S. Government corporation. GNMA is authorized to guarantee, with the full faith and credit of the U.S. Government, the timely payment of principal and interest on securities issued by institutions approved by GNMA (such as savings and loan institutions, commercial banks and mortgage bankers) and backed by pools of mortgages insured by the Federal Housing Administration (the "FHA") or guaranteed by the Department of

II-8

Veterans Affairs (the "VA"). MBS issued by GNMA include GNMA Mortgage Pass-Through Certificates (also known as "Ginnie Maes") which are guaranteed as to the timely payment of principal and interest by GNMA and such guarantees are backed by the full faith and credit of the United States. GNMA certificates also are supported by the authority of GNMA to borrow funds from the U.S. Treasury to make payments under its guarantee.

Government-related guarantors (i.e., not backed by the full faith and credit of the U.S. Government) include the Federal National Mortgage Association ("FNMA") and the Federal Home Loan Mortgage Corporation ("FHLMC"). FNMA is a government-sponsored corporation the common stock of which is owned entirely by private stockholders. FNMA purchases conventional (i.e., not insured or guaranteed by any government agency) residential mortgages from a list of approved seller/servicers which include state and federally chartered savings and loan associations, mutual savings banks, commercial banks and credit unions and mortgage bankers. Pass-through securities issued by FNMA (also known as "Fannie Maes") are guaranteed as to timely payment of principal and interest by FNMA, but are not backed by the full faith and credit of the U.S. Government. FHLMC was created by Congress in 1970 for the purpose of increasing the availability of mortgage credit for residential housing. It is a government-sponsored corporation that issues FHLMC Guaranteed Mortgage Pass-Through Certificates (also known as "Freddie Macs" or "PCs"), which are pass-through securities, each representing an undivided interest in a pool of residential mortgages. FHLMC guarantees the timely payment of interest and ultimate collection of principal, but PCs are not backed by the full faith and credit of the U.S. Government.

In 2008, the Federal Housing Finance Agency ("FHFA") placed FNMA and FHLMC into conservatorship. FNMA and FHLMC are continuing to operate as going concerns while in conservatorship and each remains liable for all of its obligations, including its guaranty obligations, associated with its MBS.

As the conservator, FHFA succeeded to all rights, titles, powers and privileges of FNMA and FHLMC and of any stockholder, officer or director of FNMA and FHLMC with respect to FNMA and FHLMC and the assets of FNMA and FHLMC. In connection with the conservatorship, the U.S. Treasury entered into a Senior Preferred Stock Purchase Agreement with each of FNMA and FHLMC pursuant to which the U.S. Treasury would purchase up to an aggregate of $100 billion of each of FNMA and FHLMC to maintain a positive net worth in each enterprise. This agreement contains various covenants that severely limit each enterprise's operations. In exchange for entering into these agreements, the U.S. Treasury received $1 billion of each enterprise's senior preferred stock and warrants to purchase 79.9% of each enterprise's common stock. In February 2009, the U.S. Treasury doubled the size of its commitment to each enterprise under the Senior Preferred Stock Program to $200 billion. The U.S. Treasury's obligations under the Senior Preferred Stock Program are for an indefinite period of time for a maximum amount of $200 billion per enterprise. In December 2009, the U.S. Treasury announced further amendments to the Senior Preferred Stock Purchase Agreements which included additional financial support to certain governmentally supported entities, including the Federal Home Loan Banks ("FHLBs"), FNMA and FHLMC. It is difficult, if not impossible, to predict the future political, regulatory or economic changes that could impact FNMA, FHLMC and the FHLBs, and the values of their related securities or obligations. There is no assurance that the obligations of such entities will be satisfied in full, or that such obligations will not decrease in value or default.

Under the Federal Housing Finance Regulatory Reform Act of 2008 (the "Reform Act"), which was included as part of the Housing and Economic Recovery Act of 2008, FHFA, as conservator or receiver, has the power to repudiate any contract entered into by FNMA or FHLMC prior to FHFA's appointment as conservator or receiver, as applicable, if FHFA determines, in its sole discretion, that performance of the contract is burdensome and that repudiation of the contract promotes the orderly administration of FNMA's or FHLMC's affairs. The Reform Act requires FHFA to exercise its right to repudiate any contract within a reasonable period of time after its appointment as conservator or receiver. FHFA, in its capacity as conservator, has indicated that it has no intention to repudiate the guaranty obligations of FNMA or FHLMC because FHFA views repudiation as incompatible with the goals of the conservatorship. However, in the event that FHFA, as conservator or if it is later appointed as receiver for FNMA or FHLMC, were to repudiate any such guaranty obligation, the conservatorship or receivership estate, as applicable, would be liable for actual direct compensatory damages in accordance with the provisions of the Reform Act. Any such liability could be satisfied only to the extent of FNMA's or FHLMC's assets available therefor. In the event of repudiation, the payments of interest to holders of FNMA or FHLMC MBS would be reduced if payments on the mortgage loans represented in the mortgage loan groups related to such MBS are not made by the borrowers or advanced by the servicer. Any actual direct compensatory damages for repudiating these guaranty obligations may not be sufficient to offset any shortfalls experienced by such mortgage-backed security holders. Further, in its

II-9

capacity as conservator or receiver, FHFA has the right to transfer or sell any asset or liability of FNMA or FHLMC without any approval, assignment or consent. Although FHFA has stated that it has no present intention to do so, if FHFA, as conservator or receiver, were to transfer any such guaranty obligation to another party, holders of FNMA or FHLMC MBS would have to rely on that party for satisfaction of the guaranty obligation and would be exposed to the credit risk of that party. In addition, certain rights provided to holders of MBS issued by FNMA and FHLMC under the operative documents related to such securities may not be enforced against FHFA, or enforcement of such rights may be delayed, during the conservatorship or any future receivership. The operative documents for FNMA and FHLMC MBS may provide (or with respect to securities issued prior to the date of the appointment of the conservator may have provided) that upon the occurrence of an event of default on the part of FNMA or FHLMC, in its capacity as guarantor, which includes the appointment of a conservator or receiver, holders of such MBS have the right to replace FNMA or FHLMC as trustee if the requisite percentage of MBS holders consent. The Reform Act prevents mortgage-backed security holders from enforcing such rights if the event of default arises solely because a conservator or receiver has been appointed.

A 2011 report to Congress from the Treasury Department and the Department of Housing and Urban Development set forth a plan to reform America's housing finance market, which would reduce the role of and eventually eliminate FNMA and FHLMC. Notably, the plan did not propose similar significant changes to GNMA, which guarantees payments on mortgage related securities backed by federally insured or guaranteed loans. The report also identified three proposals for Congress and the administration to consider for the long-term structure of the housing finance markets after the elimination of FNMA and FHLMC, including implementing: (i) a privatized system of housing finance that limits government insurance to very limited groups of creditworthy low- and moderate-income borrowers; (ii) a privatized system with a government backstop mechanism that would allow the government to insure a larger share of the housing finance market during a future housing crisis; and (iii) a privatized system where the government would offer reinsurance to holders of certain highly rated mortgage related securities insured by private insurers and would pay out under the reinsurance arrangements only if the private mortgage insurers were insolvent.

Non-Agency RMBS. These RMBS are issued by commercial banks, savings and loan institutions, mortgage bankers, private mortgage insurance companies and other non-governmental issuers. Timely payment of principal and interest on RMBS backed by pools created by non-governmental issuers often is supported partially by various forms of insurance or guarantees, including individual loan, title, pool and hazard insurance. The insurance and guarantees are issued by government entities, private insurers and the mortgage poolers. There can be no assurance that the private insurers or mortgage poolers can meet their obligations under the policies, so that if the issuers default on their obligations, the holders of the security could sustain a loss. No insurance or guarantee covers the Fund or the price of the Fund's shares. RMBS issued by non-governmental issuers generally offer a higher rate of interest than government agency and government-related securities because there are no direct or indirect government guarantees of payment.

CMBS. CMBS generally are multi-class debt or pass-through certificates secured or backed by mortgage loans on commercial properties. CMBS generally are structured to provide protection to the senior class investors against potential losses on the underlying mortgage loans. This protection generally is provided by having the holders of subordinated classes of securities ("Subordinated CMBS") take the first loss if there are defaults on the underlying commercial mortgage loans. Other protection, which may benefit all of the classes or particular classes, may include issuer guarantees, reserve funds, additional Subordinated CMBS, cross-collateralization and over-collateralization.

The Fund may invest in Subordinated CMBS, which are subordinated in some manner as to the payment of principal and/or interest to the holders of more senior CMBS arising out of the same pool of mortgages and which are often referred to as "B-Pieces." The holders of Subordinated CMBS typically are compensated with a higher stated yield than are the holders of more senior CMBS. On the other hand, Subordinated CMBS typically subject the holder to greater risk than senior CMBS and tend to be rated in a lower rating category (frequently a substantially lower rating category) than the senior CMBS issued in respect of the same mortgage pool. Subordinated CMBS generally are likely to be more sensitive to changes in prepayment and interest rates and the market for such securities may be less liquid than is the case for traditional income securities and senior CMBS.

CMOs. A CMO is a multi-class bond backed by a pool of mortgage pass-through certificates or mortgage loans. CMOs may be collateralized by (i) GNMA, FNMA or FHLMC pass-through certificates, (ii) unsecuritized

II-10

mortgage loans insured by the FHA or guaranteed by the VA, (iii) unsecuritized conventional mortgages, (iv) other MBS or (v) any combination thereof. Each class of a CMO, often referred to as a "tranche," is issued at a specific coupon rate and has a stated maturity or final distribution date. Principal prepayments on collateral underlying a CMO may cause it to be retired substantially earlier than its stated maturity or final distribution date. The principal and interest on the underlying mortgages may be allocated among the several classes of a series of a CMO in many ways. One or more tranches of a CMO may have coupon rates which reset periodically at a specified increment over an index, such as LIBOR (or sometimes more than one index). These floating rate CMOs typically are issued with lifetime caps on the coupon rate thereon.

The Fund may invest in inverse floating rate CMOs. Inverse floating rate CMOs constitute a tranche of a CMO with a coupon rate that moves in the reverse direction relative to an applicable index such as LIBOR. Accordingly, the coupon rate thereon will increase as interest rates decrease. Inverse floating rate CMOs are typically more volatile than fixed or floating rate tranches of CMOs. Many inverse floating rate CMOs have coupons that move inversely to a multiple of an index. The effect of the coupon varying inversely to a multiple of an applicable index creates a leverage factor. Inverse floating rate debt instruments ("inverse floaters") based on multiples of a stated index are designed to be highly sensitive to changes in interest rates and can subject the holders thereof to extreme reductions of yield and loss of principal. The market for inverse floating rate CMOs with highly leveraged characteristics at times may be very thin. The Fund's ability to dispose of its positions in such securities will depend on the degree of liquidity in the markets for such securities. It is impossible to predict the amount of trading interest that may exist in such securities, and therefore the future degree of liquidity.

Stripped MBS. Stripped MBS are created by segregating the cash flows from underlying mortgage loans or mortgage securities to create two or more new securities, each receiving a specified percentage of the underlying security's principal or interest payments. Mortgage securities may be partially stripped so that each investor class receives some interest and some principal. When securities are completely stripped, however, all of the interest is distributed to holders of one type of security, known as an interest-only security (or "IO"), and all of the principal is distributed to holders of another type of security, known as a principal-only security (or "PO"). Strips can be created in a pass-through structure or as tranches of a CMO. The yields to maturity on IOs and POs are very sensitive to the rate of principal payments (including prepayments) on the related underlying mortgage assets. If the underlying mortgage assets experience greater than anticipated prepayments of principal, the Fund may not fully recoup its initial investment in IOs. Conversely, if the underlying mortgage assets experience less than anticipated prepayments of principal, the yield on POs could be materially and adversely affected.

Adjustable Rate Mortgage Securities. Adjustable rate mortgages ("ARMs") have interest rates that reset at periodic intervals. Acquiring ARMs permits the Fund to participate in increases in prevailing current interest rates through periodic adjustments in the coupons of mortgages underlying the pool on which ARMs are based. Such ARMs generally have higher current yield and lower price fluctuations than is the case with more traditional fixed income securities of comparable rating and maturity. In addition, when prepayments of principal are made on the underlying mortgages during periods of rising interest rates, the Fund may potentially reinvest the proceeds of such prepayments at rates higher than those at which they were previously invested. Mortgages underlying most ARMs, however, have limits on the allowable annual or lifetime increases that can be made in the interest rate that the mortgagor pays. Therefore, if current interest rates rise above such limits over the period of the limitation, the Fund, when holding an ARM, does not benefit from further increases in interest rates. Moreover, when interest rates are in excess of the coupon rates (i.e., the rates being paid by mortgagors) of the mortgages, ARMs behave more like fixed income securities and less like adjustable-rate securities and are subject to the risks associated with fixed income securities. In addition, during periods of rising interest rates, increases in the coupon rate of ARMs generally lag current market interest rates slightly, thereby creating the potential for capital depreciation on such securities.

Sub-Prime Mortgages. Sub-prime mortgages are mortgages rated below "A" by S&P or Moody's. Historically, sub-prime mortgage loans have been made to borrowers with blemished (or non-existent) credit records, and the borrower is charged a higher interest rate to compensate for the greater risk of delinquency and the higher costs of loan servicing and collection. Sub-prime mortgages are subject to both state and federal anti-predatory lending statutes that carry potential liability to secondary market purchasers such as the Fund. Sub-prime mortgages have certain characteristics and associated risks similar to below investment grade securities, including a higher degree of credit risk, and certain characteristics and associated risks similar to MBS, including prepayment risk.

II-11

Mortgage Related ABS. Asset-backed securities ("ABS") are bonds backed by pools of loans or other receivables. ABS are created from many types of assets, including in some cases mortgage related asset classes, such as home equity loan ABS. Home equity loan ABS are subject to many of the same risks as RMBS, including interest rate risk and prepayment risk.

Mortgage REITs. A real estate investment trust ("REIT") is a corporation, or a business trust that would otherwise be taxed as a corporation, that meets the definitional requirements applicable to REITs under the Internal Revenue Code of 1986, as amended (the "Code"). The Code permits a qualifying REIT to deduct dividends paid, thereby generally eliminating corporate level U.S. federal income tax and effectively making the REIT a pass-through vehicle for U.S. federal income tax purposes. To meet the definitional requirements of the Code, a REIT must, among other things, invest substantially all of its assets in interests in real estate (including mortgages and other REITs) or cash and government securities, derive most of its income from rents from real property or interest on loans secured by mortgages on real property, and distribute to shareholders annually substantially all of its otherwise taxable income. Mortgage REITs invest mostly in mortgages on real estate, which may secure construction, development or long-term loans, and the main source of their income is mortgage interest payments. The value of securities issued by REITs is affected by tax and regulatory requirements and by perceptions of management skill. They also are subject to heavy cash flow dependency and the possibility of failing to qualify for REIT status under the Code or to maintain exemption from the 1940 Act.

Mortgage Related Derivative Instruments. The Fund may invest in MBS credit default swaps. MBS credit default swaps include swaps the reference obligation for which is an MBS or related index, such as the CMBX Index (a tradeable index referencing a basket of CMBS), the TRX Index (a tradeable index referencing total return swaps based on CMBS) or the ABX Index (a tradeable index referencing a basket of sub-prime MBS). The Fund may engage in other derivative transactions related to MBS, including purchasing and selling exchange-listed and over-the-counter put and call options, futures and forwards on mortgages and MBS. The Fund may invest in newly developed mortgage related derivatives that may hereafter become available.

Net Interest Margin (NIM) Securities. The Fund may invest in net interest margin ("NIM") securities. These securities are derivative interest-only mortgage securities structured off home equity loan transactions. NIM securities receive any "excess" interest computed after paying coupon costs, servicing costs and fees and any credit losses associated with the underlying pool of home equity loans. Like traditional stripped mortgage-backed securities, the yield to maturity on a NIM security is sensitive not only to changes in prevailing interest rates but also to the rate of principal payments (including prepayments) on the underlying home equity loans. NIM securities are highly sensitive to credit losses on the underlying collateral and the timing in which those losses are taken.

Tiered Index Bonds. Tiered index bonds are relatively new forms of mortgage-related securities. The interest rate on a tiered index bond is tied to a specified index or market rate. So long as this index or market rate is below a predetermined "strike" rate, the interest rate on the tiered index bond remains fixed. If, however, the specified index or market rate rises above the "strike" rate, the interest rate of the tiered index bond will decrease. Thus, under these circumstances, the interest rate on a tiered index bond, like an inverse floater, will move in the opposite direction of prevailing interest rates, with the result that the price of the tiered index bond may be considerably more volatile than that of a fixed-rate bond.

TBA Commitments. The Fund may enter into "to be announced" or "TBA" commitments. TBA commitments are forward agreements for the purchase or sale of securities, including mortgage-backed securities, for a fixed price, with payment and delivery on an agreed upon future settlement date. The specific securities to be delivered are not identified at the trade date. However, delivered securities must meet specified terms, including issuer, rate and mortgage terms. See "When Issued, Delayed Delivery Securities and Forward Commitment Securities" below.

Other Mortgage Related Securities. Other mortgage related securities include securities other than those described above that directly or indirectly represent a participation in, or are secured by and payable from, mortgage loans on real property. Other mortgage related securities may be equity or debt securities issued by agencies or instrumentalities of the U.S. Government or by private originators of, or investors in, mortgage loans, including savings and loan associations, homebuilders, mortgage banks, commercial banks, investment banks, partnerships, trusts and special purpose entities of the foregoing.

II-12

Asset-Backed Securities. ABS are a form of structured debt obligation. The securitization techniques used for ABS are similar to those used for MBS. ABS are bonds backed by pools of loans or other receivables. The collateral for these securities may include home equity loans, automobile and credit card receivables, boat loans, computer leases, airplane leases, mobile home loans, recreational vehicle loans and hospital account receivables. The Fund may invest in these and other types of ABS that may be developed in the future. ABS present certain risks that are not presented by mortgage related securities. Primarily, these securities may provide the Fund with a less effective security interest in the related collateral than do mortgage related securities. Therefore, there is the possibility that recoveries on the underlying collateral may not, in some cases, be available to support payments on these securities.

REITs. The Fund may invest in equity interests and debt securities issued by REITs. REITs possess certain risks which differ from an investment in common stocks. REITs are financial vehicles that pool investor's capital to purchase or finance real estate. REITs may concentrate their investments in specific geographic areas or in specific property types (i.e., hotels, shopping malls, residential complexes and office buildings). The market value of REIT shares and the ability of REITs to distribute income may be adversely affected by several factors, including rising interest rates, changes in the national, state and local economic climate and real estate conditions, perceptions of prospective tenants of the safety, convenience and attractiveness of the properties, the ability of the owners to provide adequate management, maintenance and insurance, the cost of complying with the Americans with Disabilities Act, increased competition from new properties, the impact of present or future environmental legislation and compliance with environmental laws, changes in real estate taxes and other operating expenses, adverse changes in governmental rules and fiscal policies, adverse changes in zoning laws and other factors beyond the control of the REIT issuers. In addition, distributions received by the Fund from REITs may consist of dividends, capital gains and/or return of capital. As REITs generally pay a higher rate of dividends (on a pre-tax basis) than operating companies, to the extent application of the Fund's investment strategy results in the Fund investing in REIT shares, the percentage of the Fund's dividend income received from REIT shares will likely exceed the percentage of the Fund's portfolio which is comprised of REIT shares. There are three general categories of REITs: equity REITs, mortgage REITs and hybrid REITs. Equity REITs invest primarily in direct fee ownership or leasehold ownership of real property; they derive most of their income from rents. Mortgage REITs invest mostly in mortgages on real estate, which may secure construction, development or long-term loans, and the main source of their income is mortgage interest payments. Hybrid REITs hold both ownership and mortgage interests in real estate.

Collateralized Debt Obligations. The Fund may invest in collateralized debt obligations ("CDOs"), which include collateralized bond obligations ("CBOs"), collateralized loan obligations ("CLOs") and other similarly structured securities. CDOs are types of asset-backed securities. A CBO is ordinarily issued by a trust or other special purpose entity ("SPE") and is typically backed by a diversified pool of fixed income securities (which may include high risk, below investment grade securities) held by such issuer. A CLO is ordinarily issued by a trust or other SPE and is typically collateralized by a pool of loans, which may include, among others, domestic and non-U.S. senior secured loans, senior unsecured loans, and subordinate corporate loans, including loans that may be rated below investment grade or equivalent unrated loans, held by such issuer. Although certain CDOs may benefit from credit enhancement in the form of a senior-subordinate structure, over-collateralization or bond insurance, such enhancement may not always be present, and may fail to protect the Fund against the risk of loss on default of the collateral. Certain CDO issuers may use derivatives contracts to create "synthetic" exposure to assets rather than holding such assets directly, which entails the risks of derivative instruments described elsewhere in this Prospectus. CDOs may charge management fees and administrative expenses, which are in addition to those of the Fund.

For both CBOs and CLOs, the cash flows from the SPE are split into two or more portions, called tranches, varying in risk and yield. The riskiest portion is the "equity" tranche, which bears the first loss from defaults from the bonds or loans in the SPE and serves to protect the other, more senior tranches from default (though such protection is not complete). Since it is partially protected from defaults, a senior tranche from a CBO or CLO typically has higher ratings and lower yields than its underlying securities, and may be rated investment grade. Despite the protection from the equity tranche, CBO or CLO tranches can experience substantial losses due to actual defaults, downgrades of the underlying collateral by rating agencies, forced liquidation of the collateral pool due to a failure of coverage tests, increased sensitivity to defaults due to collateral default and disappearance of protecting tranches, market anticipation of defaults as well as investor aversion to CBO or CLO securities as a class. Interest on certain tranches of a CDO may be paid in kind or deferred and capitalized (paid in the form of obligations of the same type rather than cash), which involves continued exposure to default risk with respect to such payments.

II-13

Delayed Funding Loans and Revolving Credit Facilities. The Fund may enter into, or acquire participations in, delayed funding loans and revolving credit facilities, in which a bank or other lender agrees to make loans up to a maximum amount upon demand by the borrower during a specified term. These commitments may have the effect of requiring the Fund to increase its investment in a company at a time when it might not be desirable to do so (including at a time when the company's financial condition makes it unlikely that such amounts will be repaid). Delayed funding loans and revolving credit facilities are subject to credit, interest rate and liquidity risk and the risks of being a lender.

Zero-Coupon Bonds, Step-Ups and Payment-In-Kind Securities. Zero-coupon bonds pay interest only at maturity rather than at intervals during the life of the security. Like zero-coupon bonds, "step up" bonds pay no interest initially but eventually begin to pay a coupon rate prior to maturity, which rate may increase at stated intervals during the life of the security. Payment-in-kind securities ("PIKs") are debt obligations that pay "interest" in the form of other debt obligations, instead of in cash. Each of these instruments is normally issued and traded at a deep discount from face value. Zero-coupon bonds, step-ups and PIKs allow an issuer to avoid or delay the need to generate cash to meet current interest payments and, as a result, may involve greater credit risk than bonds that pay interest currently or in cash. The Fund would be required to distribute the income on these instruments as it accrues, even though the Fund will not receive the income on a current basis or in cash. Thus, the Fund may have to sell other investments, including when it may not be advisable to do so, to make income distributions to its shareholders.

Premium Securities. The Fund may invest in income securities bearing coupon rates higher than prevailing market rates. Such "premium" securities are typically purchased at prices greater than the principal amounts payable on maturity. The Fund will not amortize the premium paid for such securities in calculating its net investment income. As a result, in such cases the purchase of such securities provides the Fund a higher level of investment income distributable to shareholders on a current basis than if the Fund purchased securities bearing current market rates of interest. Although such securities bear coupon rates higher than prevailing market rates, because they are purchased at a price in excess of par value, the yield earned by the Fund on such investments may not exceed prevailing market yields. If an issuer were to redeem securities held by the Fund during a time of declining interest rates, the Fund may not be able to reinvest the proceeds in securities providing the same investment return as the securities redeemed. If securities purchased by the Fund at a premium are called or sold prior to maturity, the Fund will recognize a capital loss to the extent the call or sale price is less than the purchase price. Additionally, the Fund will recognize a capital loss if it holds such securities to maturity.

U.S. Government Debt Securities. The Fund may invest in debt securities issued or guaranteed by the U.S. Government, its agencies or instrumentalities, including U.S. Treasury obligations, which differ in their interest rates, maturities and times of issuance. Such obligations include U.S. Treasury bills (maturity of one year or less), U.S. Treasury notes (maturity of one to ten years) and U.S. Treasury bonds (generally maturities of greater than ten years), including the principal components or the interest components issued by the U.S. Government under the separate trading of registered interest and principal securities program (i.e., "STRIPS"), all of which are backed by the full faith and credit of the United States.

Municipal Securities. The Fund may invest in municipal securities. Municipal securities are either general obligation bonds or revenue bonds and typically are issued to finance public projects, such as roads or public buildings, to pay general operating expenses or to refinance outstanding debt. Municipal securities may also be issued for private activities, such as housing, medical and educational facility construction, or for privately owned industrial development and pollution control projects. General obligation bonds are backed by the full faith and credit, or taxing authority, of the issuer and may be repaid from any revenue source. Revenue bonds may be repaid only from the revenues of a specific facility or source. Municipal securities may be issued on a long term basis to provide permanent financing. The repayment of such debt may be secured generally by a pledge of the full faith and credit taxing power of the issuer, a limited or special tax, or any other revenue source, including project revenues, which may include tolls, fees and other user charges, lease payments and mortgage payments. Municipal securities may also be issued to finance projects on a short-term interim basis, anticipating repayment with the proceeds of the later issuance of long-term debt.

General Obligation Bonds. General obligation bonds are secured by the issuer's pledge of its faith, credit and taxing power for the payment of principal and interest. The taxing power of any governmental entity may be limited, however, by provisions of its state constitution or laws, and an entity's creditworthiness will depend on many factors, including potential erosion of its tax base due to population declines, natural disasters, declines in the

II-14

state's industrial base or inability to attract new industries, economic limits on the ability to tax without eroding the tax base, state legislative proposals or voter initiatives to limit ad valorem real property taxes and the extent to which the entity relies on federal or state aid, access to capital markets or other factors beyond the state's or entity's control. Accordingly, the capacity of the issuer of a general obligation bond as to the timely payment of interest and the repayment of principal when due is affected by the issuer's maintenance of its tax base.

Revenue Bonds. Revenue bonds are payable only from the revenues derived from a particular facility or class of facilities or, in some cases, from the proceeds of a special excise tax or other specific revenue sources such as payments from the user of the facility being financed. Accordingly, the timely payment of interest and the repayment of principal in accordance with the terms of the revenue or special obligation bond is a function of the economic viability of such facility or such revenue source. Revenue bonds issued by state or local agencies to finance the development of low-income, multi-family housing involve special risks in addition to those associated with municipal securities generally, including that the underlying properties may not generate sufficient income to pay expenses and interest costs. Such bonds are generally non-recourse against the property owner, may be junior to the rights of others with an interest in the properties, may pay interest that changes based in part on the financial performance of the property, may be prepayable without penalty and may be used to finance the construction of housing developments which, until completed and rented, do not generate income to pay interest. Increases in interest rates payable on senior obligations may make it more difficult for issuers to meet payment obligations on subordinated bonds.

Moral Obligation Bonds. The Fund also may invest in "moral obligation" bonds, which are normally issued by special purpose public authorities. If an issuer of moral obligation bonds is unable to meet its obligations, the repayment of such bonds becomes a moral commitment but not a legal obligation of the state or municipality in question.

Municipal Lease Obligations. The Fund may invest in participations in lease obligations or installment purchase contract obligations (hereinafter collectively called "Municipal Lease Obligations") of municipal authorities or entities. Although a Municipal Lease Obligation does not constitute a general obligation of the municipality for which the municipality's taxing power is pledged, a Municipal Lease Obligation is ordinarily backed by the municipality's covenant to budget for, appropriate and make the payments due under the Municipal Lease Obligation. However, certain Municipal Lease Obligations contain "non-appropriation" clauses, which provide that the municipality has no obligation to make lease or installment purchase payments in future years unless money is appropriated for such purpose on a yearly basis. In the case of a "non-appropriation" lease, the Fund's ability to recover under the lease in the event of non-appropriation or default will be limited solely to the repossession of the leased property, without recourse to the general credit of the lessee, and the disposition or re-leasing of the property might prove difficult.

Certificates of Participation. A certificate of participation represents an undivided interest in an unmanaged pool of municipal leases, installment purchase agreements or other instruments. The certificates are typically issued by a municipal agency, a trust or other entity that has received an assignment of the payments to be made by the state or political subdivision under such leases or installment purchase agreements. Such certificates provide the Fund with the right to a pro rata undivided interest in the underlying municipal securities. In addition, such participations generally provide the Fund with the right to demand payment, on not more than seven days' notice, of all or any part of the Fund's participation interest in the underlying municipal securities, plus accrued interest.

Pre-Refunded Municipal Securities. The principal of, and interest on, pre-refunded municipal securities are no longer paid from the original revenue source for the securities. Instead, the source of such payments is typically an escrow fund consisting of U.S. Government securities. The assets in the escrow fund are derived from the proceeds of refunding bonds issued by the same issuer as the pre-refunded municipal securities. Issuers of municipal securities use this advance refunding technique to obtain more favorable terms with respect to securities that are not yet subject to call or redemption by the issuer. For example, advance refunding enables an issuer to refinance debt at lower market interest rates, restructure debt to improve cash flow or eliminate restrictive covenants in the indenture or other governing instrument for the pre-refunded municipal securities. However, except for a change in the revenue source from which principal and interest payments are made, the pre-refunded municipal securities remain outstanding on their original terms until they mature or are redeemed by the issuer.

II-15

Private Activity Bonds. Private activity bonds, formerly referred to as industrial development bonds, are issued by or on behalf of public authorities to obtain funds to provide privately operated housing facilities, airports, mass transit or port facilities, sewage disposal, solid waste disposal or hazardous waste treatment or disposal facilities, and certain local facilities for water supply, gas or electricity. Other types of private activity bonds, the proceeds of which are used for the construction, equipment, repair or improvement of privately operated industrial or commercial facilities, may constitute municipal securities, although the current federal tax laws place substantial limitations on the size of such issues. Such bonds are secured primarily by revenues derived from loan repayments or lease payments due from the entity, which may or may not be guaranteed by a parent company or otherwise secured. Private activity bonds generally are not secured by a pledge of the taxing power of the issuer of such bonds. Therefore, an investor should be aware that repayment of such bonds generally depends on the revenues of a private entity and be aware of the risks that such an investment may entail. Continued ability of an entity to generate sufficient revenues for the payment of principal and interest on such bonds will be affected by many factors, including the size of the entity, capital structure, demand for its products or services, competition, general economic conditions, government regulation and the entity's dependence on revenues for the operation of the particular facility being financed.

Special Taxing Districts. Special taxing districts are organized to plan and finance infrastructure developments to induce residential, commercial and industrial growth and redevelopment. Bonds issued pursuant to financing methods such as tax increment finance, tax assessment, special services district and Mello-Roos bonds (a type of municipal security established by the Mello-Roos Community Facilities District Act of 1982), are generally payable solely from taxes or other revenues attributable to the specific projects financed by the bonds without recourse to the credit or taxing power of related or overlapping municipalities. They often are exposed to real estate development-related risks and can have more taxpayer concentration risk than general tax-supported bonds, such as general obligation bonds. Further, the fees, special taxes, or tax allocations and other revenues that are established to secure such financings are generally limited as to the rate or amount that may be levied or assessed and are not subject to increase pursuant to rate covenants or municipal or corporate guarantees. The bonds could default if development failed to progress as anticipated or if larger taxpayers failed to pay the assessments, fees and taxes as provided in the financing plans of the districts.

VRDOs. Variable rate demand obligations ("VRDOs") are tax-exempt obligations that contain a floating or variable interest rate adjustment formula and right of demand on the part of the holder thereof to receive payment of the unpaid principal balance plus accrued interest upon a short notice period not to exceed seven days. There is, however, the possibility that because of default or insolvency the demand feature of VRDOs may not be honored. The interest rates are adjustable at intervals (ranging from daily to up to one year) to some prevailing market rate for similar investments, such adjustment formula being calculated to maintain the market value of the VRDOs, at approximately the par value of the VRDOs on the adjustment date. The adjustments typically are based upon SIFMA or some other appropriate interest rate adjustment index. The Fund may invest in all types of tax-exempt instruments currently outstanding or to be issued in the future. VRDOs that contain an unconditional right of demand to receive payment of the unpaid principal balance plus accrued interest on a notice period exceeding seven days may be deemed to be illiquid securities.

Taxable Municipal Securities. The Fund may invest in taxable municipal securities, including Build America Bonds ("BABs"). BABs are taxable municipal obligations issued pursuant to legislation providing for the issuance of taxable municipal debt on which the issuer receives federal support of the interest paid. Enacted in February 2009, the American Recovery and Reinvestment Act of 2009 (the "ARRA") authorizes state and local governments to issue taxable bonds on which, assuming certain specified conditions are satisfied, issuers may either (i) receive payments from the U.S. Treasury with respect to the bonds' interest payments ("direct pay" BABs) or (ii) provide tax credits to investors in the bonds ("tax credit" BABs). BABs offer an alternative form of financing to state and local governments whose primary means for accessing the capital markets has been through issuance of tax-free municipal bonds. BABs may appeal to a broader array of investors than the high income U.S. taxpayers that have traditionally provided the market for municipal bonds. Unlike most other municipal obligations, interest received on BABs is subject to federal and state income tax. Under the terms of the ARRA, issuers of direct pay BABs are entitled to receive payments from the U.S. Treasury over the life of the bond equal to 35% (or 45% in the case of Recovery Zone Economic Development Bonds) of the interest paid and investors in tax credit BABs can receive a federal tax credit of 35% of the coupon interest received. The federal interest subsidy or tax credit

II-16

continues for the life of the bonds. The Fund may invest in direct pay BABs or tax credit BABs. Pursuant to the ARRA, the issuance of BABs was discontinued on December 31, 2010.

Preferred Securities. The Fund may invest in preferred securities. There are two basic types of preferred securities. The first type, sometimes referred to as traditional preferred securities, consists of preferred stock issued by an entity taxable as a corporation. The second type, sometimes referred to as trust preferred securities, are usually issued by a trust or limited partnership and represent preferred interests in deeply subordinated debt instruments issued by the corporation for whose benefit the trust or partnership was established.

Traditional Preferred Securities. Traditional preferred securities generally pay fixed or adjustable rate dividends to investors and generally have a "preference" over common stock in the payment of dividends and the liquidation of a company's assets. This means that a company must pay dividends on preferred stock before paying any dividends on its common stock. In order to be payable, distributions on such preferred securities must be declared by the issuer's board of directors. Income payments on typical preferred securities currently outstanding are cumulative, causing dividends and distributions to accumulate even if not declared by the board of directors or otherwise made payable. In such a case all accumulated dividends must be paid before any dividend on the common stock can be paid. However, some traditional preferred stocks are non-cumulative, in which case dividends do not accumulate and need not ever be paid. A portion of the portfolio may include investments in non-cumulative preferred securities, whereby the issuer does not have an obligation to make up any arrearages to its shareholders. Should an issuer of a non-cumulative preferred stock held by the Fund determine not to pay dividends on such stock, the amount of dividends the Fund pays may be adversely affected. There is no assurance that dividends or distributions on the traditional preferred securities in which the Fund invests will be declared or otherwise made payable.

Preferred stockholders usually have no right to vote for corporate directors or on other matters. Shares of traditional preferred securities have a liquidation value that generally equals the original purchase price at the date of issuance. The market value of preferred securities may be affected by favorable and unfavorable changes impacting companies in the utilities and financial services sectors, which are prominent issuers of preferred securities, and by actual and anticipated changes in tax laws, such as changes in corporate income tax rates or the "Dividends Received Deduction." Because the claim on an issuer's earnings represented by traditional preferred securities may become onerous when interest rates fall below the rate payable on such securities, the issuer may redeem the securities. Thus, in declining interest rate environments in particular, the Fund's holdings of higher rate-paying fixed rate preferred securities may be reduced and the Fund may be unable to acquire securities of comparable credit quality paying comparable rates with the redemption proceeds.

Trust Preferred Securities. Trust preferred securities are a comparatively new asset class. Trust preferred securities are typically issued by corporations, generally in the form of interest-bearing notes with preferred security characteristics, or by an affiliated business trust of a corporation, generally in the form of beneficial interests in subordinated debentures or similarly structured securities. The trust preferred securities market consists of both fixed and adjustable coupon rate securities that are either perpetual in nature or have stated maturity dates.

Trust preferred securities are typically junior and fully subordinated liabilities of an issuer or the beneficiary of a guarantee that is junior and fully subordinated to the other liabilities of the guarantor. In addition, trust preferred securities typically permit an issuer to defer the payment of income for eighteen months or more without triggering an event of default. Generally, the deferral period is five years or more. Because of their subordinated position in the capital structure of an issuer, the ability to defer payments for extended periods of time without default consequences to the issuer, and certain other features (such as restrictions on common dividend payments by the issuer or ultimate guarantor when full cumulative payments on the trust preferred securities have not been made), these trust preferred securities are often treated as close substitutes for traditional preferred securities, both by issuers and investors. Trust preferred securities have many of the key characteristics of equity due to their subordinated position in an issuer's capital structure and because their quality and value are heavily dependent on the profitability of the issuer rather than on any legal claims to specific assets or cash flows.

Convertible Securities. A convertible security is a bond, debenture, note, preferred security or other security that may be converted into or exchanged for a prescribed amount of common stock or other equity security of the same or a different issuer within a particular period of time at a specified price or formula. A convertible security entitles the holder to receive interest paid or accrued on debt or the dividend paid on preferred stock until

the convertible security matures or is redeemed, converted or exchanged. Before conversion, convertible securities have characteristics similar to nonconvertible income securities in that they ordinarily provide a stable stream of income with generally higher yields than those of common stocks of the same or similar issuers, but lower yields than comparable nonconvertible securities. The value of a convertible security is influenced by changes in interest rates, with investment value declining as interest rates increase and increasing as interest rates decline. The credit standing of the issuer and other factors also may have an effect on the convertible security's investment value. Convertible securities rank senior to common stock in a corporation's capital structure but are usually subordinated to comparable nonconvertible securities. Convertible securities may be subject to redemption at the option of the issuer at a price established in the convertible security's governing instrument.

A "synthetic" or "manufactured" convertible security may be created by the Fund or by a third party by combining separate securities that possess the two principal characteristics of a traditional convertible security: an income producing component and a convertible component. The income-producing component is achieved by investing in non-convertible, income-producing securities such as bonds, preferred stocks and money market instruments. The convertible component is achieved by investing in securities or instruments such as warrants or options to buy common stock at a certain exercise price, or options on a stock index. Unlike a traditional convertible security, which is a single security having a single market value, a synthetic convertible comprises two or more separate securities, each with its own market value. Because the "market value" of a synthetic convertible security is the sum of the values of its income-producing component and its convertible component, the value of a synthetic convertible security may respond differently to market fluctuations than a traditional convertible security. The Fund also may purchase synthetic convertible securities created by other parties, including convertible structured notes. Convertible structured notes are income-producing debentures linked to equity. Convertible structured notes have the attributes of a convertible security; however, the issuer of the convertible note (typically an investment bank), rather than the issuer of the underlying common stock into which the note is convertible, assumes credit risk associated with the underlying investment and the Fund in turn assumes credit risk associated with the issuer of the convertible note.

Restricted and Illiquid Securities. The Fund may invest in illiquid or less liquid securities or securities in which no secondary market is readily available or which are otherwise illiquid, including private placement securities. "Illiquid securities" are securities which cannot be sold within seven days in the ordinary course of business at approximately the value used by the Fund in determining its NAV. Illiquid securities are subject to legal or contractual restrictions on disposition or lack an established secondary trading market. The sale of restricted and illiquid securities often requires more time and results in higher brokerage charges or dealer discounts and other selling expenses than does the sale of securities eligible for trading on national securities exchanges or in the over-the-counter markets. Restricted securities may sell at a price lower than similar securities that are not subject to restrictions on resale.

Non-U.S. Securities. The Fund may invest in securities of non-U.S. issuers ("Non-U.S. Securities"). Subject to the Fund's investment policies, these securities may be U.S. dollar-denominated or non-U.S. dollar-denominated and include: (i) debt obligations issued or guaranteed by foreign national, provincial, state, municipal or other governments with taxing authority or by their agencies or instrumentalities, including securities created through the exchange of existing commercial bank loans to sovereign entities for new obligations in connection with debt restructurings, commonly referred to as "Brady Bonds;" (ii) debt obligations of supranational entities; (iii) debt obligations and other debt securities of foreign corporate issuers; (iv) fixed income securities issued by corporations that generate significant profits from non-U.S. countries; and (v) structured securities, including but not limited to, warrants, options and other derivatives, whose price is directly linked to Non-U.S. Securities or indices of Non-U.S. Securities. Some Non-U.S. Securities may be less liquid and more volatile than securities of comparable U.S. issuers. Similarly, there is less volume and liquidity in most foreign securities markets than in the United States and, at times, greater price volatility than in the United States. Because evidence of ownership of such securities usually is held outside the United States, the Fund will be subject to additional risks if it invests in Non-U.S. Securities, which include adverse political and economic developments, seizure or nationalization of foreign deposits and adoption of governmental restrictions which might adversely affect or restrict the payment of principal and interest on the foreign securities to investors located outside the country of the issuer, whether from currency blockage or otherwise. Non-U.S. Securities may trade on days when the common shares are not priced or traded.

II-18

Emerging Markets Investments. The Fund may invest in securities of issuers located in emerging market countries, including securities denominated in currencies of emerging market countries. Emerging market countries generally include every nation in the world except the United States, Canada, Japan, Australia, New Zealand and most countries located in Western Europe. These issuers may be subject to risks that do not apply to issuers in larger, more developed countries. These risks are more pronounced to the extent the Fund invests significantly in one country. Less information about non-U.S. issuers or markets may be available due to less rigorous disclosure and accounting standards or regulatory practices. Many non-U.S. markets are smaller, less liquid and more volatile than U.S. markets. In a changing market, the Investment Advisor may not be able to sell the Fund's portfolio securities in amounts and at prices it considers reasonable. The U.S. dollar may appreciate against non-U.S. currencies or an emerging market government may impose restrictions on currency conversion or trading. The economies of non-U.S. countries may grow at a slower rate than expected or may experience a downturn or recession. Economic, political and social developments may adversely affect non-U.S. securities markets.

Equity Securities. The Fund may invest in equity securities, including common stocks and warrants. Common stock represents an equity ownership interest in a company. The Fund may hold or have exposure to common stocks of issuers of any size, including small and medium capitalization stocks. Warrants are privileges issued by corporations enabling the owners to subscribe to and purchase a specified number of shares of the corporation at a specified price during a specified period of time. Subscription rights normally have a short life span to expiration. The purchase of warrants involves the risk that the Fund could lose the purchase value of a right or warrant if the right to subscribe to additional shares is not exercised prior to the warrants' expiration. Also, the purchase of warrants involves the risk that the effective price paid for the warrant added to the subscription price of the related security may exceed the value of the subscribed security's market price such as when there is no movement in the level of the underlying security. Buying a warrant does not make the Fund a shareholder of the underlying stock.

Sovereign Governmental and Supranational Debt. The Fund may invest in all types of debt securities of governmental issuers in all countries, including emerging market countries. These sovereign debt securities may include: debt securities issued or guaranteed by governments, governmental agencies or instrumentalities and political subdivisions; debt securities issued by government owned, controlled or sponsored entities; interests in entities organized and operated for the purpose of restructuring the investment characteristics of instruments issued by any of the above issuers; Brady Bonds, which are debt securities issued under the framework of the Brady Plan as a means for debtor nations to restructure their outstanding external indebtedness; participations in loans between governments and financial institutions; or debt securities issued by supranational entities such as the World Bank. A supranational entity is a bank, commission or company established or financially supported by the national governments of one or more countries to promote reconstruction or development. Sovereign government and supranational debt involve all the risks described herein regarding foreign and emerging markets investments as well as the risk of debt moratorium, repudiation or renegotiation.

Brady Bonds are debt securities, generally denominated in U.S. dollars, issued under the framework of the Brady Plan as a means for debtor nations to restructure their outstanding external indebtedness. In restructuring its external debt under the Brady Plan framework, a debtor nation negotiates with its existing bank lenders as well as multilateral institutions such as the World Bank and the International Monetary Fund (the "IMF"). The Brady Plan framework, as it has developed, contemplates the exchange of external commercial bank debt for newly issued bonds known as "Brady Bonds." Brady Bonds may also be issued in respect of new money being advanced by existing lenders in connection with the debt restructuring. The World Bank and/or the IMF support the restructuring by providing funds pursuant to loan agreements or other arrangements which enable the debtor nation to collateralize the new Brady Bonds or to repurchase outstanding bank debt at a discount. Under these arrangements with the World Bank and/or the IMF, debtor nations have been required to agree to the implementation of certain domestic monetary and fiscal reforms. Such reforms have included the liberalization of trade and foreign investment, the privatization of state-owned enterprises and the setting of targets for public spending and borrowing. These policies and programs seek to promote the debtor country's economic growth and development. Investors should also recognize that the Brady Plan only sets forth general guiding principles for economic reform and debt reduction, emphasizing that solutions must be negotiated on a case-by-case basis between debtor nations and their creditors.

Brady Bonds involve various risk factors described elsewhere associated with investing in foreign securities, including the history of defaults with respect to commercial bank loans by public and private entities of

II-19

countries issuing Brady Bonds. In light of the residual risk of Brady Bonds and, among other factors, the history of defaults, investments in Brady Bonds are considered speculative. There can be no assurance that Brady Bonds in which the Fund may invest will not be subject to restructuring arrangements or to requests for new credit, which may cause the Fund to suffer a loss of interest or principal on any of its holdings.

Inflation-Indexed Bonds. Inflation-indexed bonds (other than municipal inflation-indexed bonds and certain corporate inflation-indexed bonds) are fixed income securities the principal value of which is periodically adjusted according to the rate of inflation. If the index measuring inflation falls, the principal value of inflation-indexed bonds (other than municipal inflation-indexed bonds and certain corporate inflation-indexed bonds) will be adjusted downward, and consequently the interest payable on these securities (calculated with respect to a smaller principal amount) will be reduced. Repayment of the original bond principal upon maturity (as adjusted for inflation) is guaranteed in the case of U.S. Treasury inflation-indexed bonds ("TIPs"). For bonds that do not provide a similar guarantee, the adjusted principal value of the bond repaid at maturity may be less than the original principal. With regard to municipal inflation-indexed bonds and certain corporate inflation-indexed bonds, the inflation adjustment is typically reflected in the semi-annual coupon payment. As a result, the principal value of municipal inflation-indexed bonds and such corporate inflation-indexed bonds does not adjust according to the rate of inflation.

Variable and Floating Rate Instruments. Variable and floating rate securities provide for a periodic adjustment in the interest rate paid on the obligations. The terms of such obligations provide that interest rates are adjusted periodically based upon an interest rate adjustment index as provided in the respective obligations. The adjustment intervals may be regular, and range from daily up to annually, or may be event-based, such as based on a change in the prime rate.

The interest rate on a floating rate debt instrument ("floater") is a variable rate which is tied to another interest rate, such as a money-market index or Treasury bill rate. The interest rate on a floater resets periodically, typically every six months. Because of the interest rate reset feature, floaters provide the Fund with a certain degree of protection against rises in interest rates, although the Fund will participate in any declines in interest rates as well.

Inverse Floating Rate Securities. An inverse floater is a type of debt instrument that bears a floating or variable interest rate that moves in the opposite direction to interest rates generally or the interest rate on another security or index. Changes in interest rates generally, or the interest rate of the other security or index, inversely affect the interest rate paid on the inverse floater, with the result that the inverse floater's price will be considerably more volatile than that of a fixed rate bond. The Fund may invest in inverse floaters, which brokers typically create by depositing an income-producing instrument, including a mortgage related security, in a trust. The trust in turn issues a variable rate security and inverse floaters. The interest rate for the variable rate security is typically determined by an index or an auction process, while the inverse floater holder receives the balance of the income from the underlying income-producing instrument less an auction fee. The market prices of inverse floaters may be highly sensitive to changes in interest rates and prepayment rates on the underlying securities, and may decrease significantly when interest rates increase or prepayment rates change. In a transaction in which the Fund purchases an inverse floater from a trust, and the underlying security was held by the Fund prior to being deposited into the trust, the Fund typically treats the transaction as a secured borrowing for financial reporting purposes. As a result, for financial reporting purposes, the Fund will generally incur a non-cash interest expense with respect to interest paid by the trust on the variable rate securities and will recognize additional interest income in an amount directly corresponding to the non-cash interest expense. Therefore, the Fund's NAV per common share and performance are not affected by the non-cash interest expense. This accounting treatment does not apply to inverse floaters acquired by the Fund when the Fund did not previously own the underlying bond.

Strategic Transactions and Other Management Techniques. The Fund may use a variety of other investment management techniques and instruments. The Fund may purchase and sell futures contracts, enter into various interest rate transactions such as swaps, caps, floors or collars, currency transactions such as currency forward contracts, currency futures contracts, currency swaps or options on currency or currency futures and swap contracts (including, but not limited to, credit default swaps) and may purchase and sell exchange-listed and over-the-counter put and call options on securities and swap contracts, financial indices and futures contracts and use other derivative instruments or management techniques (collectively, "Strategic Transactions"). These Strategic Transactions may be used for duration management and other risk management purposes, including to attempt to protect against possible changes in the market value of the Fund's portfolio resulting from trends in the securities markets and changes in interest rates or to protect the Fund's unrealized gains in the value of its portfolio securities,

II-20

to facilitate the sale of portfolio securities for investment purposes, to establish a position in the securities markets as a temporary substitute for purchasing particular securities or, to the extent applicable, to enhance income or gain. There is no particular strategy that requires use of one technique rather than another as the decision to use any particular strategy or instrument is a function of market conditions and the composition of the portfolio. The use of Strategic Transactions to enhance current income may be particularly speculative. The ability of the Fund to use Strategic Transactions successfully will depend on the Investment Advisor's ability to predict pertinent market movements as well as sufficient correlation among the instruments, which cannot be assured. The use of Strategic Transactions may result in losses greater than if they had not been used, may require the Fund to sell or purchase portfolio securities at inopportune times or for prices other than current market values, may limit the amount of appreciation the Fund can realize on an investment or may cause the Fund to hold a security that it might otherwise sell. Inasmuch as any obligations of the Fund that arise from the use of Strategic Transactions will be covered by liquid assets designated on its books and records or offsetting transactions, the Fund and the Investment Advisor believe such obligations do not constitute senior securities and, accordingly, will not treat such transactions as being subject to its borrowing restrictions or policies regarding economic leverage. Additionally, liquid assets designated on the Fund's books and records, amounts paid by the Fund as premiums and cash or other assets held in margin accounts with respect to Strategic Transactions are not otherwise available to the Fund for investment purposes. Certain provisions of the Code may restrict or affect the ability of the Fund to engage in Strategic Transactions. In addition, the use of certain Strategic Transactions may give rise to taxable income and have certain other consequences. See "Risk Factors—Strategic Transactions and Derivatives Risks" under Item 8.

Swaps and Swaptions. The Fund may enter into swap agreements, including interest rate and index swap agreements. Swap agreements are two party contracts entered into primarily by institutional investors for periods ranging from a few weeks to more than one year. In a standard "swap" transaction, two parties agree to exchange the returns (or differentials in rates of return) earned or realized on particular predetermined investments or instruments. The gross returns to be exchanged or "swapped" between the parties are calculated with respect to a "notional amount," i.e., the dollar amount invested at a particular interest rate, in a particular foreign currency, or in a "basket" of securities representing a particular index. The "notional amount" of the swap agreement is only a fictive basis on which to calculate the obligations that the parties to a swap agreement have agreed to exchange. The Fund's obligations (or rights) under a swap agreement will generally be equal only to the net amount to be paid or received under the agreement based on the relative values of the positions held by each party to the agreement (the "net amount"). The Fund's obligations under a swap agreement will be accrued daily (offset against any amounts owing to the Fund) and the Fund will designate on its books and records an amount of cash or liquid assets having an aggregate NAV at all times at least equal to any accrued but unpaid net amounts owed to a swap counterparty.

Whether the Fund's use of swap agreements will be successful in furthering its investment objective will depend on the Investment Advisor's ability to correctly predict whether certain types of investments are likely to produce greater returns than other investments. Moreover, the Fund bears the risk of loss of the amount expected to be received under a swap agreement in the event of the default or bankruptcy of a swap agreement counterparty. Swap agreements also bear the risk that the Fund will not be able to meet its payment obligations to the counterparty. As noted, however, the Fund will designate on its books and records liquid assets in an amount equal to or greater than the market value of the Fund's liabilities under the swap agreement or the amount it would cost the Fund initially to make an equivalent direct investment plus or minus any amount the Fund is obligated to pay or is to receive under the swap agreement. Restrictions imposed by the tax rules applicable to regulated investment companies may limit the Fund's ability to use swap agreements. The regulation of the swap market is undergoing significant change as a result of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the "Dodd-Frank Act"). See "Risk Factors—Strategic Transactions and Derivatives Risks—Dodd-Frank Act Risk" under Item 8. It is possible that developments in the swap market, including government regulation, could adversely affect the Fund's ability to terminate existing swap agreements or to realize amounts to be received under such agreements.

A swaption is a contract that gives a counterparty the right (but not the obligation) to enter into a new swap agreement or to shorten, extend, cancel or otherwise modify an existing swap agreement, at some designated future time on specified terms. The Fund may write (sell) and purchase put and call swaptions. Depending on the terms of the particular option agreement, the Fund will generally incur a greater degree of risk when it writes a swaption than it will incur when it purchases a swaption. When the Fund purchases a swaption, it risks losing only the amount of the premium it has paid should it decide to let the option expire unexercised. However, when the Fund writes a

II-21

swaption, upon exercise of the option the Fund will become obligated according to the terms of the underlying agreement.

Credit Default Swaps. The Fund may enter into credit default swap agreements. The credit default swap agreement may have as reference obligations one or more securities that are not currently held by the Fund. The protection "buyer" in a credit default contract may be obligated to pay the protection "seller" an upfront or a periodic stream of payments over the term of the contract, provided that no credit event on the reference obligation has occurred. If a credit event occurs, the seller generally must pay the buyer the "par value" (full notional amount) of the swap in exchange for an equal face amount of deliverable obligations of the reference entity described in the swap, or if the swap is cash settled the seller may be required to deliver the related net cash amount (the difference between the market value of the reference obligation and its par value). The Fund may be either the buyer or seller in the transaction. If the Fund is a buyer and no credit event occurs, the Fund will generally receive no payments from its counterparty under the swap if the swap is held through its termination date. However, if a credit event occurs, the buyer generally may elect to receive the full notional amount of the swap in exchange for an equal face amount of deliverable obligations of the reference entity, the value of which may have significantly decreased. As a seller, the Fund generally receives an upfront payment or a fixed rate of income throughout the term of the swap, which typically is between six months and three years, provided that there is no credit event. If a credit event occurs, generally the seller must pay the buyer the full notional amount of the swap in exchange for an equal face amount of deliverable obligations of the reference entity, the value of which may have significantly decreased. As the seller, the Fund would effectively add leverage to its portfolio because, in addition to its Managed Assets, the Fund would be subject to investment exposure on the notional amount of the swap.

Credit default swap agreements involve greater risks than if the Fund had taken a position in the reference obligation directly (either by purchasing or selling) since, in addition to general market risks, credit default swaps are subject to illiquidity risk, counterparty risk and credit risks. A buyer generally will also lose its upfront payment or any periodic payments it makes to the seller counterparty and receive no payments from its counterparty should no credit event occur and the swap is held to its termination date. If a credit event were to occur, the value of any deliverable obligation received by the seller, coupled with the upfront or periodic payments previously received, may be less than the full notional amount it pays to the buyer, resulting in a loss of value to the seller. A seller of a credit default swap or similar instrument is exposed to many of the same risks of leverage since, if a credit event occurs, the seller generally will be required to pay the buyer the full notional amount of the contract net of any amounts owed by the buyer related to its delivery of deliverable obligations. The Fund's obligations under a credit default swap agreement will be accrued daily (offset against any amounts owed to the Fund). The Fund will at all times designate on its books and records in connection with each such transaction liquid assets or cash with a value at least equal to the Fund's exposure (any accrued but unpaid net amounts owed by the Fund to any counterparty) on a marked-to-market basis (as calculated pursuant to requirements of the SEC). If the Fund is a seller of protection in a credit default swap transaction, it will designate on its books and records in connection with such transaction liquid assets or cash with a value at least equal to the full notional amount of the contract. Such designation will ensure that the Fund has assets available to satisfy its obligations with respect to the transaction and will avoid any potential leveraging of the Fund's portfolio. Such designation will not limit the Fund's exposure to loss.

In addition, the credit derivatives market is subject to a changing regulatory environment. It is possible that regulatory or other developments in the credit derivatives market could adversely affect the Fund's ability to successfully use credit derivatives.

Total Return Swaps. Total return swap agreements are contracts in which one party agrees to make periodic payments to another party based on the change in market value of the assets underlying the contract, which may include a specified security, basket of securities or securities indices during the specified period, in return for periodic payments based on a fixed or variable interest rate or the total return from other underlying assets. Total return swap agreements may be used to obtain exposure to a security or market without owning or taking physical custody of such security or investing directly in such market. Total return swap agreements may effectively add leverage to the Fund's portfolio because, in addition to its Managed Assets, the Fund would be subject to investment exposure on the notional amount of the swap.

Total return swap agreements are subject to the risk that a counterparty will default on its payment obligations to the Fund thereunder. Swap agreements also bear the risk that the Fund will not be able to meet its obligation to the counterparty. Generally, the Fund will enter into total return swaps on a net basis (i.e., the two

II-22

payment streams are netted against one another with the Fund receiving or paying, as the case may be, only the net amount of the two payments). The net amount of the excess, if any, of the Fund's obligations over its entitlements with respect to each total return swap will be accrued on a daily basis, and an amount of liquid assets having an aggregate net asset value at least equal to the accrued excess will be designated by the Fund on its books and records. If the total return swap transaction is entered into on other than a net basis, the full amount of the Fund's obligations will be accrued on a daily basis, and the full amount of the Fund's obligations will be designated by the Fund on its books and records in an amount equal to or greater than the market value of the liabilities under the total return swap agreement or the amount it would have cost the Fund initially to make an equivalent direct investment, plus or minus any amount the Fund is obligated to pay or is to receive under the total return swap agreement.

Interest Rate Transactions. The Fund may enter into various interest rate transactions such as interest rate swaps and the purchase or sale of interest rate caps and floors. The Fund may enter into these transactions to seek to preserve a return or spread on a particular investment or portion of its portfolio, to seek to protect against any increase in the price of securities the Fund anticipates purchasing at a later date or, to the extent applicable, to seek to enhance its return or to seek to increase the Fund's yield, for example, during periods of steep interest rate yield curves (i.e., wide differences between short term and long term interest rates). The Fund is not required to pursue these portfolio strategies and may choose not to do so. The Fund cannot guarantee that any strategies it uses will work.

In an interest rate swap, the Fund exchanges with another party their respective commitments to pay or receive interest (e.g., an exchange of fixed rate payments for floating rate payments). For example, if the Fund holds a debt instrument with an interest rate that is reset only once each year, it may swap the right to receive interest at this fixed rate for the right to receive interest at a rate that is reset every week. This would enable the Fund to offset a decline in the value of the debt instrument due to rising interest rates but would also limit its ability to benefit from falling interest rates. Conversely, if the Fund holds a debt instrument with an interest rate that is reset every week and it would like to lock in what it believes to be a high interest rate for one year, it may swap the right to receive interest at this variable weekly rate for the right to receive interest at a rate that is fixed for one year. Such a swap would protect the Fund from a reduction in yield due to falling interest rates and may permit the Fund to enhance its income through the positive differential between one week and one year interest rates, but would preclude it from taking full advantage of rising interest rates.

The Fund usually will enter into interest rate swaps on a net basis (i.e., the two payment streams are netted out with the Fund receiving or paying, as the case may be, only the net amount of the two payments). The net amount of the excess, if any, of the Fund's obligations over its entitlements with respect to each interest rate swap will be accrued on a daily basis, and an amount of cash or liquid assets having an aggregate net asset value at least equal to the accrued excess will be designated by the Fund on its books and records. If the interest rate swap transaction is entered into on other than a net basis, the full amount of the Fund's obligations will be accrued on a daily basis, and the full amount of the Fund's obligations will be designated by the Fund.

The Fund also may engage in interest rate transactions in the form of purchasing or selling interest rate caps or floors. The purchase of an interest rate cap entitles the purchaser, to the extent that a specified index exceeds a predetermined interest rate, to receive payments of interest equal to the difference of the index and the predetermined rate on a notional principal amount (i.e., the reference amount with respect to which interest obligations are determined although no actual exchange of principal occurs) from the party selling such interest rate cap. The purchase of an interest rate floor entitles the purchaser, to the extent that a specified index falls below a predetermined interest rate, to receive payments of interest at the difference of the index and the predetermined rate on a notional principal amount from the party selling such interest rate floor.

Typically, the parties with which the Fund will enter into interest rate transactions will be broker dealers and other financial institutions. If there is a default by the other party to an uncleared interest rate swap transaction, generally the Fund will have contractual remedies pursuant to the agreements related to the transaction. With respect to interest rate swap transactions cleared through a central clearing counterparty, a clearing organization will be substituted for each party and will guaranty the parties' performance under the swap agreement. However, there can be no assurance that the clearing organization will satisfy its obligation to the Fund. Certain Federal income tax requirements may limit the Fund's ability to engage in interest rate swaps. Payments from transactions in interest rate swaps generally will be taxable as ordinary income to shareholders. See "Tax Matters" under Item 10.

II-23

Foreign Currency Transactions. The Fund's common shares are priced in U.S. dollars and the distributions paid by the Fund to common shareholders are paid in U.S. dollars. However, a portion of the Fund's assets may be denominated in non-U.S. currencies and the income received by the Fund from such securities will be paid in non-U.S. currencies. The Fund also may invest in or gain exposure to non-U.S. currencies. The Fund's investments in securities that trade in, or receive revenues in, non-U.S. currencies will be subject to currency risk, which is the risk that fluctuations in the exchange rates between the U.S. dollar and foreign currencies may negatively affect an investment. The Fund may (but is not required to) hedge some or all of its exposure to non-U.S. currencies through the use of derivative strategies, including forward foreign currency exchange contracts, foreign currency futures contracts and options on foreign currencies and foreign currency futures. Suitable hedging transactions may not be available in all circumstances and there can be no assurance that the Fund will engage in such transactions at any given time or from time to time when they would be beneficial. Although the Fund has the flexibility to engage in such transactions, the Investment Advisor may determine not to do so or to do so only in unusual circumstances or market conditions. These transactions may not be successful and may eliminate any chance for the Fund to benefit from favorable fluctuations in relevant foreign currencies. The Fund may also, to the extent applicable, use derivatives contracts for purposes of increasing exposure to a foreign currency or to shift exposure to foreign currency fluctuations from one currency to another.

Foreign Exchange Transactions. The Fund may engage in spot and forward foreign exchange transactions and currency swaps, purchase and sell options on currencies and purchase and sell currency futures and related options thereon (collectively, "Currency Instruments"). Such transactions could be effected with respect to hedges on foreign dollar denominated securities owned by the Fund, sold by the Fund but not yet delivered, or committed or anticipated to be purchased by the Fund. As an illustration, the Fund may use such techniques to hedge the stated value in U.S. dollars of an investment in a yen-denominated security. In such circumstances, for example, the Fund may purchase a foreign currency put option enabling it to sell a specified amount of yen for dollars at a specified price by a future date. To the extent the hedge is successful, a loss in the value of the yen relative to the dollar will tend to be offset by an increase in the value of the put option. To offset, in whole or in part, the cost of acquiring such a put option, the Fund may also sell a call option which, if exercised, requires it to sell a specified amount of yen for dollars at a specified price by a future date (a technique called a "straddle"). By selling such a call option in this illustration, the Fund gives up the opportunity to profit without limit from increases in the relative value of the yen to the dollar. "Straddles" of the type that may be used by the Fund are considered to constitute hedging transactions. The Fund may not attempt to hedge any or all of its foreign portfolio positions.

Forward Foreign Currency Contracts. The Fund may enter into forward currency contracts to purchase or sell foreign currencies for a fixed amount of U.S. dollars or another foreign currency. A forward currency contract involves an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days (term) from the date of the forward currency contract agreed upon by the parties, at a price set at the time the forward currency contract is entered into. Forward currency contracts are traded directly between currency traders (usually large commercial banks) and their customers. The Fund may purchase a forward currency contract to lock in the U.S. dollar price of a security denominated in a foreign currency that the Fund intends to acquire. The Fund may sell a forward currency contract to lock in the U.S. dollar equivalent of the proceeds from the anticipated sale of a security or a dividend or interest payment denominated in a foreign currency. The Fund may also, to the extent applicable, use forward currency contracts to shift the Fund's exposure to foreign currency exchange rate changes from one currency to another. For example, if the Fund owns securities denominated in a foreign currency and the Investment Advisor believes that currency will decline relative to another currency, the Fund might enter into a forward currency contract to sell the appropriate amount of the first foreign currency with payment to be made in the second currency. The Fund may also, to the extent applicable, purchase forward currency contracts to enhance income when the Investment Advisor anticipates that the foreign currency will appreciate in value but securities denominated in that currency do not present attractive investment opportunities. The Fund may also use forward currency contracts to hedge against a decline in the value of existing investments denominated in a foreign currency. Such a hedge would tend to offset both positive and negative currency fluctuations, but would not offset changes in security values caused by other factors. The Fund could also hedge the position by entering into a forward currency contract to sell another currency expected to perform similarly to the currency in which the Fund's existing investments are denominated. This type of transaction could offer advantages in terms of cost, yield or efficiency, but may not hedge currency exposure as effectively as a simple forward currency transaction to sell U.S. dollars. This type of transaction may result in losses if the currency used to hedge does not perform similarly to the currency in which the hedged securities are denominated. The Fund may also use forward currency contracts in one currency

II-24

or a basket of currencies to attempt to hedge against fluctuations in the value of securities denominated in a different currency if the Investment Advisor anticipates that there will be a correlation between the two currencies.

The cost to the Fund of engaging in forward currency contracts varies with factors such as the currency involved, the length of the contract period and the market conditions then prevailing. Because forward currency contracts are usually entered into on a principal basis, no fees or commissions are involved. When the Fund enters into a forward currency contract, it relies on the counterparty to make or take delivery of the underlying currency at the maturity of the contract. Failure by the counterparty to do so would result in the loss of some or all of any expected benefit of the transaction. Secondary markets generally do not exist for forward currency contracts, with the result that closing transactions generally can be made for forward currency contracts only by negotiating directly with the counterparty. Thus, there can be no assurance that the Fund will in fact be able to close out a forward currency contract at a favorable price prior to maturity. In addition, in the event of insolvency of the counterparty, the Fund might be unable to close out a forward currency contract. In either event, the Fund would continue to be subject to market risk with respect to the position, and would continue to be required to maintain a position in securities denominated in the foreign currency or to designate cash or liquid assets on its books and records. The precise matching of forward currency contract amounts and the value of the securities involved generally will not be possible because the value of such securities, measured in the foreign currency, will change after the forward currency contract has been established. Thus, the Fund might need to purchase or sell foreign currencies in the spot (cash) market to the extent such foreign currencies are not covered by forward currency contracts. The projection of short-term currency market movements is extremely difficult and the successful execution of a short-term hedging strategy is highly uncertain.

Call Options. The Fund may purchase call options on any of the types of securities or instruments in which it may invest. A purchased call option gives the Fund the right to buy, and obligates the seller to sell, the underlying security at the exercise price at any time during the option period. The Fund also may purchase and sell call options on indices. Index options are similar to options on securities except that, rather than taking or making delivery of securities underlying the option at a specified price upon exercise, an index option gives the holder the right to receive cash upon exercise of the option if the level of the index upon which the option is based is greater than the exercise price of the option.

The Fund also may write (i.e., sell) covered call options on the securities or instruments in which it may invest and to enter into closing purchase transactions with respect to certain of such options. A covered call option is an option in which the Fund, in return for a premium, gives another party a right to buy specified securities owned by the Fund at a specified future date and price set at the time of the contract. The principal reason for writing call options is the attempt to realize, through the receipt of premiums, a greater return than would be realized on the securities alone. By writing covered call options, the Fund gives up the opportunity, while the option is in effect, to profit from any price increase in the underlying security above the option exercise price. In addition, the Fund's ability to sell the underlying security will be limited while the option is in effect unless the Fund enters into a closing purchase transaction. A closing purchase transaction cancels out the Fund's position as the writer of an option by means of an offsetting purchase of an identical option prior to the expiration of the option it has written. Covered call options also serve as a partial hedge to the extent of the premium received against the price of the underlying security declining.

The Fund also may write (i.e., sell) uncovered call options on securities or instruments in which it may invest but that are not currently held by the Fund. The principal reason for writing uncovered call options is to realize income without committing capital to the ownership of the underlying securities or instruments. When writing uncovered call options, the Fund must deposit and maintain sufficient margin with the broker dealer through which it made the uncovered call option as collateral to ensure that the securities can be purchased for delivery if and when the option is exercised. In addition, in connection with each such transaction the Fund will designate on its books and records liquid assets or cash with a value at least equal to the Fund's exposure (the difference between the unpaid amounts owed by the Fund on such transaction minus any collateral deposited with the broker dealer), on a marked-to-market basis (as calculated pursuant to requirements of the SEC). Such designation will ensure that the Fund has assets available to satisfy its obligations with respect to the transaction and will avoid any potential leveraging of the Fund's portfolio. Such designation will not limit the Fund's exposure to loss. During periods of declining securities prices or when prices are stable, writing uncovered calls can be a profitable strategy to increase the Fund's income with minimal capital risk. Uncovered calls are riskier than covered calls because there is no

II-25

underlying security held by the Fund that can act as a partial hedge. Uncovered calls have speculative characteristics and the potential for loss is unlimited. When an uncovered call is exercised, the Fund must purchase the underlying security to meet its call obligation. There is also a risk, especially with less liquid preferred and debt securities, that the securities may not be available for purchase. If the purchase price exceeds the exercise price, the Fund will lose the difference.

Put Options. The Fund may purchase put options. By buying a put option, the Fund acquires a right to sell such underlying securities or instruments at the exercise price, thus limiting the Fund's risk of loss through a decline in the market value of the securities or instruments until the put option expires. The amount of any appreciation in the value of the underlying securities or instruments will be partially offset by the amount of the premium paid for the put option and any related transaction costs. Prior to its expiration, a put option may be sold in a closing sale transaction and profit or loss from the sale will depend on whether the amount received is more or less than the premium paid for the put option plus the related transaction costs. A closing sale transaction cancels out the Fund's position as the purchaser of an option by means of an offsetting sale of an identical option prior to the expiration of the option it has purchased. The Fund also may purchase uncovered put options.

The Fund also may write (i.e., sell) put options on the types of securities or instruments that may be held by the Fund, provided that such put options are covered, meaning that such options are secured by liquid assets designated on the Fund's books and records. The Fund will receive a premium for writing a put option, which increases the Fund's return.

The Fund may write (i.e., sell) uncovered put options on securities or instruments in which it may invest but that the Fund does not currently have a corresponding short position or has not deposited cash equal to the exercise value of the put option with the broker dealer through which it made the uncovered put option as collateral. The principal reason for writing uncovered put options is to receive premium income and to acquire such securities or instruments at a net cost below the current market value. The Fund has the obligation to buy the securities or instruments at an agreed upon price if the securities or instruments decrease below the exercise price. If the securities or instruments price increases during the option period, the option will expire worthless and the Fund will retain the premium and will not have to purchase the securities or instruments at the exercise price. In connection with such transaction, the Fund will designate on its books and records liquid assets or cash with a value at least equal to the Fund's exposure, on a marked-to-market basis (as calculated pursuant to requirements of the SEC). Such designation will ensure that the Fund has assets available to satisfy its obligations with respect to the transaction and will avoid any potential leveraging of the Fund's portfolio. Such designation will not limit the Fund's exposure to loss.

Futures Contracts and Options on Futures Contracts. The Fund may engage in transactions in financial futures contracts ("futures contracts") and related options on such futures contracts. A futures contract is an agreement between two parties which obligates the purchaser of the futures contract to buy and the seller of a futures contract to sell a security for a set price on a future date or, in the case of an index futures contract, to make and accept a cash settlement based upon the difference in value of the index between the time the contract was entered into and the time of its settlement. A majority of transactions in futures contracts, however, do not result in the actual delivery of the underlying instrument or cash settlement, but are settled through liquidation (i.e., by entering into an offsetting transaction). Futures contracts have been designed by boards of trade which have been designated "contract markets" by the CFTC.

The Fund may sell financial futures contracts in anticipation of an increase in the general level of interest rates. Generally, as interest rates rise, the market values of securities that may be held by the Fund will fall, thus reducing the NAV of the Fund. However, as interest rates rise, the value of the Fund's short position in the futures contract also will tend to increase, thus offsetting all or a portion of the depreciation in the market value of the Fund's investments which are being hedged. While the Fund will incur commission expenses in selling and closing out futures positions, these commissions are generally less than the transaction expenses which the Fund would have incurred had the Fund sold portfolio securities in order to reduce its exposure to increases in interest rates. The Fund also may purchase financial futures contracts in anticipation of a decline in interest rates when it is not fully invested in a particular market in which it intends to make investments to gain market exposure that may in part or entirely offset an increase in the cost of securities it intends to purchase. It is anticipated that, in a substantial majority of these transactions, the Fund will purchase securities upon termination of the futures contract.

II-26

The Fund also may purchase and write call and put options on futures contracts. Options on futures contracts are similar to options on securities except that an option on a futures contract gives the purchaser the right in return for the premium paid to assume a position in a futures contract (a long position if the option is a call and a short position if the option is a put). Generally, these strategies are utilized under the same market and market sector conditions (i.e., conditions relating to specific types of investments) in which the Fund enters into futures transactions. The Fund may purchase put options or write call options on futures contracts rather than selling the underlying futures contract in anticipation of a decrease in the market value of securities or an increase in interest rates. Similarly, the Fund may purchase call options, or write put options on futures contracts, as a substitute for the purchase of such futures to hedge against the increased cost resulting from an increase in the market value or a decline in interest rates of securities which the Fund intends to purchase.

The Fund may engage in options and futures transactions on exchanges and options in the over-the-counter markets. In general, exchange-traded contracts are third-party contracts (i.e., performance of the parties' obligation is guaranteed by an exchange or clearing corporation) with standardized strike prices and expiration dates. OTC options transactions are two-party contracts with price and terms negotiated by the buyer and seller. See "Put and Call Options – Additional Information," below.

When a Fund purchases a futures contract or writes a put option or purchases a call option thereon, an amount of cash or liquid assets will be designated on the Fund's books and records so that the amount so designated, plus the amount of variation margin held in the account of its broker, equals the market value of the futures contract, thereby ensuring that the use of such futures is unleveraged.

At the time a futures contract is purchased or sold, the Fund must allocate cash or securities as a deposit payment ("initial margin"). The initial margin that the Fund may pay typically ranges from approximately 1% to approximately 5% of the value of the securities or commodities underlying the contract but could vary from these ranges. In certain circumstances, however, such as periods of high volatility, the Fund may be required by an exchange to increase the level of its initial margin payment. Additionally, initial margin requirements may be increased generally in the future by regulatory action. An outstanding futures contract is valued daily and the payment in case of "variation margin" may be required, a process known as "marking to the market." Transactions in listed options and futures are usually settled by entering into an offsetting transaction, and are subject to the risk that the position may not be able to be closed if no offsetting transaction can be arranged.

Futures contracts, interest rate swaps, caps, floors and collars, short sales, reverse repurchase agreements and dollar rolls, and listed or OTC options on securities, indices and futures contracts sold by the Fund are generally subject to earmarking and coverage requirements of either the CFTC or the SEC, with the result that, if the Fund does not hold the security or futures contract underlying the instrument, the Fund will be required to designate on its books and records an ongoing basis, cash, U.S. Government securities, or other liquid assets in an amount at least equal to the Fund's obligations with respect to such instruments. Such amounts fluctuate as the obligations increase or decrease. The earmarking requirement can result in the Fund maintaining securities positions it would otherwise liquidate, earmarking assets at a time when it might be disadvantageous to do so or otherwise restrict portfolio management.

Put and Call Options – Additional Information. In the case of either put or call options that it has purchased, if the option expires without being sold or exercised, the Fund will experience a loss in the amount of the option premium plus any commissions paid by the Fund. When the Fund sells put and call options, it receives a premium as the seller of the option. The premium that the Fund receives for selling the option will serve as a partial and limited (to the dollar amount of the premium) hedge, in the amount of the option premium, against changes in the value of the securities in its portfolio. During the term of the option, however, a covered call seller has, in return for the premium on the option, given up the opportunity for capital appreciation above the exercise price of the option if the value of the underlying security increases, but has retained the risk of loss should the price of the underlying security decline. Conversely, a put seller retains the risk of loss should the market value of the underlying security decline below the exercise price of the option, less the premium received on the sale of the option. The Fund may purchase and sell exchange-listed options and over-the-counter options ("OTC Options") which are privately negotiated with the counterparty. Listed options are issued by the Options Clearing Corporation ("OCC") which guarantees the performance of the obligations of the parties to such options.

II-27

The Fund's ability to close out its position as a purchaser or seller of an exchange-listed put or call option is dependent upon the existence of a liquid secondary market on option exchanges. Among the possible reasons for the absence of a liquid secondary market on an exchange are: (i) insufficient trading interest in certain options; (ii) restrictions on transactions imposed by an exchange; (iii) trading halts, suspensions or other restrictions imposed with respect to particular classes or series of options or underlying securities; (iv) interruption of the normal operations on an exchange; (v) inadequacy of the facilities of an exchange or OCC to handle current trading volume; or (vi) a decision by one or more exchanges to discontinue the trading of options (or a particular class or series of options), in which event the secondary market on that exchange (or in that class or series of options) would cease to exist, although outstanding options on that exchange that had been listed by the OCC as a result of trades on that exchange would generally continue to be exercisable in accordance with their terms. OTC Options are purchased from or sold to dealers, financial institutions or other counterparties which have entered into direct agreements with the Fund. With OTC Options, such variables as expiration date, exercise price and premium will be agreed upon between the Fund and the counterparty, without the intermediation of a third party such as the OCC. If the counterparty fails to make or take delivery of the securities underlying an option it has written, or otherwise settle the transaction in accordance with the terms of that option as written, the Fund would lose the premium paid for the option as well as any anticipated benefit of the transaction. OTC Options and assets used to cover OTC Options written by the Fund are considered by the staff of the SEC to be illiquid. The illiquidity of such options or assets may prevent a successful sale of such options or assets, result in a delay of sale, or reduce the amount of proceeds that might otherwise be realized.

The hours of trading for options on debt securities may not conform to the hours during which the underlying securities are traded. To the extent that the option markets close before the markets for the underlying securities, significant price and rate movements can take place in the underlying markets that cannot be reflected in the option markets.

Structured Instruments. The Fund may invest in structured instruments. While structured instruments may offer the potential for a favorable rate of return from time to time, they also entail certain risks. Structured instruments may be less liquid than other securities and the price of structured instruments may be more volatile. In some cases, depending on the terms of the embedded index, a structured instrument may provide that the principal and/or interest payments may be adjusted below zero. Structured instruments also may involve significant credit risk and risk of default by the counterparty. Structured instruments may also be illiquid. Like other sophisticated strategies, the Fund's use of structured instruments may not work as intended.

Structured Notes. The Fund may invest in "structured" notes and other related instruments, which are privately negotiated debt obligations in which the principal and/or interest is determined by reference to the performance of a benchmark asset, market or interest rate (an "embedded index"), such as selected securities, an index of securities or specified interest rates, or the differential performance of two assets or markets. Structured instruments may be issued by corporations, including banks, as well as by governmental agencies. Structured instruments frequently are assembled in the form of medium-term notes, but a variety of forms are available and may be used in particular circumstances. The terms of such structured instruments normally provide that their principal and/or interest payments are to be adjusted upwards or downwards (but ordinarily not below zero) to reflect changes in the embedded index while the structured instruments are outstanding. As a result, the interest and/or principal payments that may be made on a structured product may vary widely, depending on a variety of factors, including the volatility of the embedded index and the effect of changes in the embedded index on principal and/or interest payments. The rate of return on structured notes may be determined by applying a multiplier to the performance or differential performance of the referenced index(es) or other asset(s). Application of a multiplier involves leverage that will serve to magnify the potential for gain and the risk of loss.

Event-Linked Securities. The Fund may obtain event-linked exposure by investing in "event-linked bonds" or "event-linked swaps" or by implementing "event-linked strategies." Event-linked exposure results in gains or losses that typically are contingent upon, or formulaically related to, defined trigger events. Examples of trigger events include hurricanes, earthquakes, weather-related phenomena or statistics relating to such events. Some event-linked bonds are commonly referred to as "catastrophe bonds." If a trigger event occurs, the Fund may lose a portion of or its entire principal invested in the bond or the entire notional amount of a swap. Event-linked exposure often provides for an extension of maturity to process and audit loss claims when a trigger event has, or possibly has, occurred. An extension of maturity may increase volatility. Event-linked exposure may also expose the Fund to

II-28

certain other risks including credit risk, counterparty risk, adverse regulatory or jurisdictional interpretations and adverse tax consequences. Event-linked exposures may also be subject to liquidity risk.

Equity-Linked Notes. Equity-linked notes are hybrid securities with characteristics of both fixed income and equity securities. An equity-linked note is a debt instrument, usually a bond, that pays interest based upon the performance of an underlying equity, which can be a single stock, basket of stocks or an equity index. Instead of paying a predetermined coupon, equity-linked notes link the interest payment to the performance of a particular equity market index or basket of stocks or commodities. The interest payment is typically based on the percentage increase in an index from a predetermined level, but alternatively may be based on a decrease in the index. The interest payment may in some cases be leveraged so that, in percentage terms, it exceeds the relative performance of the market. Equity-linked notes generally are subject to the risks associated with the securities of equity issuers, default risk and counterparty risk.

Credit Linked Securities. The Fund may invest in credit linked securities, which are issued by a limited purpose trust or other vehicle that, in turn, invests in a derivative instrument or basket of derivative instruments, such as credit default swaps, interest rate swaps and other securities, in order to provide exposure to certain fixed income markets. For instance, the Fund may invest in credit linked securities as a cash management tool in order to gain exposure to a certain market and/or to remain fully invested when more traditional income producing securities are not available.

Like an investment in a bond, investments in these credit linked securities represent the right to receive periodic income payments (in the form of distributions) and payment of principal at the end of the term of the security. However, these payments are conditioned on the issuer's receipt of payments from, and the issuer's potential obligations to, the counterparties to the derivative instruments and other securities in which the issuer invests. For instance, the issuer may sell one or more credit default swaps, under which the issuer would receive a stream of payments over the term of the swap agreements provided that no event of default has occurred with respect to the referenced debt obligation upon which the swap is based. If a default occurs, the stream of payments may stop and the issuer would be obligated to pay the counterparty the par (or other agreed upon value) of the referenced debt obligation. This, in turn, would reduce the amount of income and principal that the Fund would receive. The Fund's investments in these instruments are indirectly subject to the risks associated with derivative instruments, including, among others, credit risk, default or similar event risk, counterparty risk, interest rate risk, leverage risk and management risk. It is also expected that the securities will be exempt from registration under the Securities Act. Accordingly, there may be no established trading market for the securities and they may constitute illiquid investments.

Hybrid Securities. A hybrid instrument is a type of potentially high-risk derivative that combines a traditional bond, stock or commodity with an option or forward contract. Generally, the principal amount, amount payable upon maturity or redemption, or interest rate of a hybrid is tied (positively or negatively) to the price of some commodity, currency or securities index or another interest rate or some other economic factor (each a "benchmark"). The interest rate or (unlike most fixed income securities) the principal amount payable at maturity of a hybrid security may be increased or decreased, depending on changes in the value of the benchmark. An example of a hybrid could be a bond issued by an oil company that pays a small base level of interest with additional interest that accrues in correlation to the extent to which oil prices exceed a certain predetermined level. Such a hybrid instrument would be a combination of a bond and a call option on oil. Hybrids can be used as an efficient means of pursuing a variety of investment goals, including currency hedging, duration management and increased total return. Hybrids may not bear interest or pay dividends. The value of a hybrid or its interest rate may be a multiple of a benchmark and, as a result, may be leveraged and move (up or down) more steeply and rapidly than the benchmark. These benchmarks may be sensitive to economic and political events, such as commodity shortages and currency devaluations, which cannot be readily foreseen by the purchaser of a hybrid. Under certain conditions, the redemption value of a hybrid could be zero. Thus, an investment in a hybrid may entail significant market risks that are not associated with a similar investment in a traditional, U.S. dollar-denominated bond that has a fixed principal amount and pays a fixed rate or floating rate of interest. The purchase of hybrids also exposes the Fund to the credit risk of the issuer of the hybrids. These risks may cause significant fluctuations in the NAV of the Fund's common shares if the Fund invests in hybrid instruments.

Other Investment Companies. As a shareholder in an investment company (which could include an exchange-traded fund ("ETF") or a business development company ("BDC")), the Fund will bear its ratable share of

II-29

that investment company's expenses and will remain subject to payment of the Fund's advisory and other fees and expenses with respect to assets so invested. Holders of common shares will therefore be subject to duplicative expenses to the extent the Fund invests in other investment companies. The Investment Advisor will take expenses into account when evaluating the investment merits of an investment in an investment company relative to available equity and/or fixed income securities investments. In addition, the securities of other investment companies may also be leveraged and will therefore be subject to the same leverage risks to which the Fund is subject. As described in this Prospectus in "Risk Factors" and "Leverage" under Item 8 in Part II, the NAV and market value of securities of other investment companies that are leveraged will be more volatile and the yield to shareholders will tend to fluctuate more than the yield generated by unleveraged shares. Investment companies in which the Fund may invest may have investment policies that differ from those of the Fund. In addition, to the extent the Fund invests in other investment companies, the Fund will be dependent upon the investment and research abilities of persons other than the Investment Advisor.

Repurchase Agreements. The Fund may invest in repurchase agreements. A repurchase agreement is a contractual agreement whereby the seller of securities agrees to repurchase the same security at a specified price on a future date agreed upon by the parties. The agreed upon repurchase price determines the yield during the Fund's holding period. Repurchase agreements are considered to be loans collateralized by the underlying security that is the subject of the repurchase contract. Income generated from transactions in repurchase agreements will be taxable. The risk to the Fund is limited to the ability of the issuer to pay the agreed upon repurchase price on the delivery date; however, although the value of the underlying collateral at the time the transaction is entered into always equals or exceeds the agreed upon repurchase price, if the value of the collateral declines there is a risk of loss of both principal and interest. In the event of default, the collateral may be sold but the Fund might incur a loss if the value of the collateral declines, and might incur disposition costs or experience delays in connection with liquidating the collateral. In addition, if bankruptcy proceedings are commenced with respect to the seller of the security, realization upon the collateral by the Fund may be delayed or limited. The Investment Advisor will monitor the value of the collateral at the time the transaction is entered into and at all times subsequent during the term of the repurchase agreement in an effort to determine that such value always equals or exceeds the agreed upon repurchase price. In the event the value of the collateral declines below the repurchase price, the Investment Advisor will demand additional collateral from the issuer to increase the value of the collateral to at least that of the repurchase price, including interest.

A purchase and sale contract is similar to a repurchase agreement, but differs from a repurchase agreement in that the contract arrangements stipulate that the securities are owned by the Fund. In the event of a default under such a repurchase agreement or a purchase and sale contract, instead of the contractual fixed rate of return, the rate of return to the Fund shall be dependent upon intervening fluctuations of the market value of such security and the accrued interest on the security. In such event, the Fund would have rights against the seller for breach of contract with respect to any losses arising from market fluctuations following the failure of the seller to perform.

Reverse Repurchase Agreements. The Fund may enter into reverse repurchase agreements with respect to its portfolio investments subject to the investment restrictions set forth herein. Reverse repurchase agreements involve the sale of securities held by the Fund with an agreement by the Fund to repurchase the securities at an agreed upon price, date and interest payment. At the time the Fund enters into a reverse repurchase agreement, it may designate on its books and records cash and/or liquid assets having a value not less than the repurchase price (including accrued interest). If the Fund earmarks such assets, a reverse repurchase agreement will not be considered a senior security under the 1940 Act and therefore will not be considered a borrowing by the Fund; however, under certain circumstances in which the Fund does not earmark such assets, such reverse repurchase agreement will be considered a borrowing for the purpose of the Fund's limitation on borrowings. The use by the Fund of reverse repurchase agreements involves many of the same risks of leverage since the proceeds derived from such reverse repurchase agreements may be invested in additional securities. The Fund's use of leverage through reverse repurchase agreements will be subject to the Fund's policy with respect to the use of leverage. Reverse repurchase agreements involve the risk that the market value of the securities acquired in connection with the reverse repurchase agreement may decline below the price of the securities the Fund has sold but is obligated to repurchase. Also, reverse repurchase agreements involve the risk that the market value of the securities retained in lieu of sale by the Fund in connection with the reverse repurchase agreement may decline in price.

II-30

If the buyer of securities under a reverse repurchase agreement files for bankruptcy or becomes insolvent, such buyer or its trustee or receiver may receive an extension of time to determine whether to enforce the Fund's obligation to repurchase the securities and the Fund's use of the proceeds of the reverse repurchase agreement may effectively be restricted pending such decision. Also, the Fund would bear the risk of loss to the extent that the proceeds of the reverse repurchase agreement are less than the value of the securities subject to such agreement.

The Fund also may effect simultaneous purchase and sale transactions that are known as "sale-buybacks." A sale-buyback is similar to a reverse repurchase agreement, except that in a sale-buyback, the counterparty that purchases the security is entitled to receive any principal or interest payments made on the underlying security pending settlement of the Fund's repurchase of the underlying security.

Dollar Rolls. The Fund may enter into "dollar roll" transactions. In a dollar roll transaction, the Fund sells a mortgage related security to a dealer and simultaneously agrees to repurchase a similar security (but not the same security) in the future at a pre-determined price. A dollar roll transaction can be viewed, like a reverse repurchase agreement, as a collateralized borrowing in which the Fund pledges a mortgage related security to a dealer to obtain cash. However, unlike reverse repurchase agreements, the dealer with which the Fund enters into a dollar roll transaction is not obligated to return the same securities as those originally sold by the Fund, but rather only securities which are "substantially identical," which generally means that the securities repurchased will bear the same interest rate and a similar maturity as those sold, but pools of mortgages collateralizing those securities may have different prepayment histories than those sold. As with reverse repurchase agreements, to the extent that positions in dollar roll agreements are not covered by liquid assets designated on the Fund's books and records at least equal to the amount of any forward purchase commitment, such transactions would be deemed senior securities representing indebtedness for purposes of the 1940 Act.

During the period between the sale and repurchase, the Fund will not be entitled to receive interest and principal payments of the securities sold. Proceeds of the sale will be invested in additional instruments for the Fund and the income from these investments will generate income for the Fund. If such income does not exceed the income, capital appreciation and gain or loss that would have been realized on the securities sold as part of the dollar roll, the use of this technique will diminish the investment performance of the Fund compared with what the performance would have been without the use of dollar rolls. At the time the Fund enters into a dollar roll transaction, it will designate on its books and records cash, U.S. Government securities or other liquid assets having a value equal to the repurchase price (including accrued interest).

Dollar roll transactions involve the risk that the market value of the securities the Fund is required to purchase may decline below the agreed upon repurchase price of those securities. The Fund's right to purchase or repurchase securities may be restricted. Successful use of mortgage dollar rolls may depend upon the investment manager's ability to correctly predict interest rates and prepayments. There is no assurance that dollar rolls can be successfully employed.

Short Sales. The Fund may make short sales of securities. A short sale is a transaction in which the Fund sells a security it does not own in anticipation that the market price of that security will decline. The Fund may make short sales to hedge positions, for duration and risk management, in order to maintain portfolio flexibility or, to the extent applicable, to enhance income or gain. When the Fund makes a short sale, it must borrow the security sold short and deliver it to the broker-dealer through which it made the short sale as collateral for its obligation to deliver the security upon conclusion of the sale. The Fund may have to pay a fee to borrow particular securities and is often obligated to pay over to the securities lender any income, distributions or dividends received on such borrowed securities until it returns the security to the securities lender. The Fund's obligation to replace the borrowed security will be secured by collateral deposited with the securities lender, usually cash, U.S. Government securities or other liquid assets. The Fund will also be required to designate on its books and records cash or liquid assets to the extent, if any, necessary so that the aggregate collateral value is at all times at least equal to the current market value of the security sold short. Depending on arrangements made with the securities lender regarding payment over of any income, distributions or dividends received by the Fund on such security, the Fund may not receive any payments (including interest) on its collateral deposited with such securities lender. If the price of the security sold short increases between the time of the short sale and the time the Fund replaces the borrowed security, the Fund will incur a loss; conversely, if the price declines, the Fund will realize a gain. Any gain will be decreased, and any loss increased, by the transaction costs described above. Although the Fund's gain is limited to the price at which it sold the security short, its potential loss is theoretically unlimited. The Fund may also make short sales "against the box."

II-31

In this type of short sale, at the time of the sale, the Fund owns or has the immediate and unconditional right to acquire at no additional cost the identical security.

Bank Obligations. Bank obligations may include certificates of deposit, bankers' acceptances and fixed time deposits. Certificates of deposit are negotiable certificates issued against funds deposited in a commercial bank for a definite period of time and earning a specified return. Bankers' acceptances are negotiable drafts or bills of exchange, normally drawn by an importer or exporter to pay for specific merchandise, which are "accepted" by a bank, meaning, in effect, that the bank unconditionally agrees to pay the face value of the instrument on maturity. Fixed time deposits are bank obligations payable at a stated maturity date and bearing interest at a fixed rate. Fixed time deposits may be withdrawn on demand by the investor, but may be subject to early withdrawal penalties, which vary depending upon market conditions and the remaining maturity of the obligation. There are no contractual restrictions on the right to transfer a beneficial interest in a fixed time deposit to a third party, although there is no market for such deposits.

Obligations of foreign banks involve somewhat different investment risks than those affecting obligations of U.S. banks, including the possibilities that their liquidity could be impaired because of future political and economic developments, that their obligations may be less marketable than comparable obligations of U.S. banks, that a foreign jurisdiction might impose withholding taxes on interest income payable on those obligations, that foreign deposits may be seized or nationalized, that foreign governmental restrictions such as exchange controls may be adopted which might adversely affect the payment of principal and interest on those obligations and that the selection of those obligations may be more difficult because there may be less publicly available information concerning foreign banks or the accounting, auditing and financial reporting standards, practices and requirements applicable to foreign banks may differ from those applicable to U.S. banks. Foreign banks are not generally subject to examination by any U.S. Government agency or instrumentality.

Participation Notes. The Fund may buy participation notes from a bank or broker-dealer ("issuer") that entitle the Fund to a return measured by the change in value of an identified underlying security or basket of securities (collectively, the "underlying security"). Participation notes are typically used when a direct investment in the underlying security is restricted due to country-specific regulations.

The Fund is subject to counterparty risk associated with each issuer. Investment in a participation note is not the same as investment in the constituent shares of the company. A participation note represents only an obligation of the issuer to provide the Fund the economic performance equivalent to holding shares of an underlying security. A participation note does not provide any beneficial or equitable entitlement or interest in the relevant underlying security. In other words, shares of the underlying security are not in any way owned by the Fund. However each participation note synthetically replicates the economic benefit of holding shares in the underlying security. Because a participation note is an obligation of the issuer, rather than a direct investment in shares of the underlying security, the Fund may suffer losses potentially equal to the full value of the participation note if the issuer fails to perform its obligations.

The counterparty may, but is not required to, purchase the shares of the underlying security to hedge its obligation. The Fund may, but is not required to, purchase credit protection against the default of the issuer. When the participation note expires or the Fund exercises the participation note and closes its position, the Fund receives a payment that is based upon the then-current value of the underlying security converted into U.S. dollars (less transaction costs). The price, performance and liquidity of the participation note are all linked directly to the underlying security. The Fund's ability to redeem or exercise a participation note generally is dependent on the liquidity in the local trading market for the security underlying the participation note.

When-Issued, Delayed Delivery Securities and Forward Commitment Securities. The Fund may purchase securities on a "when-issued" basis and may purchase or sell securities on a "forward commitment" basis (including on a "TBA" (to be announced) basis) or on a "delayed delivery" basis. When such transactions are negotiated, the price, which is generally expressed in yield terms, is fixed at the time the commitment is made, but delivery and payment for the securities take place at a later date. When-issued securities and forward commitments may be sold prior to the settlement date. If the Fund disposes of the right to acquire a when-issued security prior to its acquisition or disposes of its right to deliver or receive against a forward commitment, it might incur a gain or loss. At the time the Fund enters into a transaction on a when-issued or forward commitment basis, it will segregate or designate on its books and records cash or liquid assets with a value not less than the value of the when-issued or forward

II-32

commitment securities. The value of these assets will be monitored daily to ensure that their marked to market value will at all times equal or exceed the corresponding obligations of the Fund. Pursuant to recommendations of the Treasury Market Practices Group, which is sponsored by the Federal Reserve Board of New York, the Fund or its counterparty generally is required to post collateral when entering into certain forward-settling transactions, including without limitation TBA transactions.

There is always a risk that the securities may not be delivered and that the Fund may incur a loss. Settlements in the ordinary course are not treated by the Fund as when-issued or forward commitment transactions and accordingly are not subject to the foregoing restrictions.

Standby Commitment Agreements. The Fund from time to time may enter into standby commitment agreements. Such agreements commit the Fund, for a stated period of time, to purchase a stated amount of a fixed income security that may be issued and sold to the Fund at the option of the issuer. The price and coupon of the security is fixed at the time of the commitment. At the time of entering into the agreement the Fund may be paid a commitment fee, regardless of whether or not the security ultimately is issued. The Fund will enter into such agreements only for the purpose of investing in the security underlying the commitment at a yield and price which is considered advantageous to the Fund. The Fund at all times will designate on its books and records cash or other liquid assets with a value equal to the purchase price of the securities underlying the commitment.

There can be no assurance that the securities subject to a standby commitment will be issued and the value of the security, if issued, on the delivery date may be more or less than its purchase price. Since the issuance of the security underlying the commitment is at the option of the issuer, the Fund may bear the risk of decline in the value of such security and may not benefit from an appreciation in the value of the security during the commitment period.

The purchase of a security subject to a standby commitment agreement and the related commitment fee will be recorded on the date on which the security reasonably can be expected to be issued and the value of the security thereafter will be reflected in the calculation of the Fund's NAV. The cost basis of the security will be adjusted by the amount of the commitment fee. In the event the security is not issued, the commitment fee will be recorded as income on the expiration date of the standby commitment.

Temporary Defensive Positions; Invest-Up Period. During temporary defensive periods, if the Investment Advisor determines that market conditions warrant, and also during the period in which the net proceeds of this offering of common shares (or preferred shares, should the Fund determine to issue preferred shares in the future) are being invested, the Fund may invest any percentage of its assets without limitation in cash, cash equivalents, money market securities, such as U.S. Treasury and agency obligations, other U.S. Government securities, short-term debt obligations of corporate issuers, certificates of deposit, bankers acceptances, commercial paper (short-term, unsecured, negotiable promissory notes of a domestic or foreign issuer), repurchase agreements, obligations of supranational organizations, bank obligations, including U.S. subsidiaries and branches of foreign banks, or other high quality fixed income securities. Temporary defensive positions may affect the Fund's ability to achieve its investment objective. Generally, such obligations will mature within one year from the date of settlement, but may mature within two years from the date of settlement.

Short-Term Debt Securities. Short-term debt securities include, without limitation:

U.S. Government securities, including bills, notes and bonds differing as to maturity and rates of interest that are either issued or guaranteed by the U.S. Treasury or by U.S. Government agencies or instrumentalities. U.S. Government securities include securities issued by (a) the FHA, Farmers Home Administration, Export-Import Bank of the United States, Small Business Administration and GNMA, whose securities are supported by the full faith and credit of the United States; (b) the FHLBs, Federal Intermediate Credit Banks, and Tennessee Valley Authority, whose securities are supported by the right of the agency to borrow from the U.S. Treasury; (c) FNMA, whose securities are supported by the discretionary authority of the U.S. Government to purchase certain obligations of the agency or instrumentality; and (d) the Student Loan Marketing Association, whose securities are supported only by its credit. While the U.S. Government provides financial support to such U.S. Government-sponsored agencies or instrumentalities, no assurance can be given that it always will do so since it is not so obligated by law.

II-33

Certificates of deposit issued against funds deposited in a bank or a savings and loan association. Such certificates are for a definite period of time, earn a specified rate of return, and are normally negotiable. The issuer of a certificate of deposit agrees to pay the amount deposited plus interest to the bearer of the certificate on the date specified thereon. Certificates of deposit purchased by the Fund may not be fully insured by the Federal Deposit Insurance Corporation.

Repurchase agreements, which involve purchases of debt securities.

Commercial paper, which consists of short-term unsecured promissory notes, including variable rate master demand notes issued by corporations to finance their current operations. Master demand notes are direct lending arrangements between the Fund and a corporation. There is no secondary market for such notes. However, they are redeemable by the Fund at any time. The Investment Advisor will consider the financial condition of the corporation (e.g., earning power, cash flow and other liquidity ratios) and will continuously monitor the corporation's ability to meet all of its financial obligations, because the Fund's liquidity might be impaired if the corporation were unable to pay principal and interest on demand.

New Products. The financial markets continue to evolve and financial products continue to be developed. The Fund reserves the right to invest in new financial products as they are developed or become more widely accepted. As with any new financial product, these products will entail risks, including risks to which the Fund currently is not subject.

Securities Lending. The Fund may lend portfolio securities to certain borrowers determined to be creditworthy by BlackRock, including to borrowers affiliated with BlackRock. The borrowers provide collateral that is maintained in an amount at least equal to the current market value of the securities loaned. No securities loan shall be made on behalf of the Fund if, as a result, the aggregate value of all securities loans of the Fund exceeds one-third of the value of the Fund's total assets (including the value of the collateral received). The Fund may terminate a loan at any time and obtain the return of the securities loaned. The Fund receives the value of any interest or cash or non-cash distributions paid on the loaned securities.

With respect to loans that are collateralized by cash, the borrower may be entitled to receive a fee based on the amount of cash collateral. The Fund is compensated by the difference between the amount earned on the reinvestment of cash collateral and the fee paid to the borrower. In the case of collateral other than cash, the Fund is compensated by a fee paid by the borrower equal to a percentage of the market value of the loaned securities. Any cash collateral received by the Fund for such loans, and uninvested cash, may be invested, among other things, in a private investment company managed by an affiliate of the Investment Advisor or in registered money market funds advised by the Investment Advisor or its affiliates; such investments are subject to investment risk.

The Fund conducts its securities lending pursuant to an exemptive order from the SEC permitting it to lend portfolio securities to borrowers affiliated with the Fund and to retain an affiliate of the Fund as lending agent. To the extent that the Fund engages in securities lending, BlackRock Investment Management, LLC ("BIM"), an affiliate of the Investment Advisor, acts as securities lending agent for the Fund, subject to the overall supervision of the Investment Advisor. BIM administers the lending program in accordance with guidelines approved by the Board. Pursuant to the current securities lending agreement, BIM may lend securities only when the difference between the borrower rebate rate and the risk free rate exceeds a certain level (such securities, the "specials only securities").

To the extent that the Fund engages in securities lending, the Fund retains a portion of securities lending income and remits a remaining portion to BIM as compensation for its services as securities lending agent. Securities lending income is equal to the total of income earned from the reinvestment of cash collateral (and excludes collateral investment expenses as defined below), and any fees or other payments to and from borrowers of securities. As securities lending agent, BIM bears all operational costs directly related to securities lending. The Fund is responsible for expenses in connection with the investment of cash collateral received for securities on loan in a private investment company managed by an affiliate of the Investment Advisor, however, BIM has agreed to cap the collateral investment expenses the Fund bears to an annual rate of 0.04% of the daily net assets of such private investment company (the "collateral investment expenses"). In addition, in accordance with the exemptive

II-34

order, the investment adviser to the private investment company will not charge any advisory fees with respect to shares purchased by the Fund. Such shares also will not be subject to a sales load, redemption fee, distribution fee or service fee.

Pursuant to the current securities lending agreement, the Fund retains 80% of securities lending income (which excludes collateral investment expenses).

In addition, commencing the business day following the date that the aggregate securities lending income earned across the Closed-End Complex in a calendar year exceeds the breakpoint dollar threshold applicable in the given year set forth in the securities lending agreement, the Fund, pursuant to the current securities lending agreement, will receive for the remainder of that calendar year securities lending income in an amount equal to 85% of securities lending income (which excludes collateral investment expenses).

Leverage

The Fund uses leverage to seek to achieve its investment objectives as set forth in Part I. The use of leverage can create risks. When leverage is employed, the NAV and market price of the common shares and the yield to holders of common shares will be more volatile than if leverage were not used. Changes in the value of the Fund's portfolio, including securities bought with the proceeds of leverage, will be borne entirely by the holders of common shares. If there is a net decrease or increase in the value of the Fund's investment portfolio, leverage will decrease or increase, as the case may be, the NAV per common share to a greater extent than if the Fund did not utilize leverage. A reduction in the Fund's NAV may cause a reduction in the market price of its shares. During periods in which the Fund is using leverage, the fees paid to the Investment Advisor for advisory services will be higher than if the Fund did not use leverage, because the fees paid will be calculated on the basis of the Fund's Managed Assets, which includes the proceeds from leverage. The Fund's leveraging strategy may not be successful. See "Risk Factors—Leverage Risk," above.

Certain types of leverage by the Fund may result in the Fund being subject to covenants relating to asset coverage and portfolio composition requirements. The Fund may be subject to certain restrictions on investments imposed by one or more lenders or by guidelines of one or more rating agencies, which may issue ratings for any short-term debt securities or preferred shares issued by the Fund. The terms of any borrowings or rating agency guidelines may impose asset coverage or portfolio composition requirements that are more stringent than those imposed by the 1940 Act. The Investment Advisor does not believe that these covenants or guidelines will impede it from managing the Fund's portfolio in accordance with its investment objective and policies if the Fund were to utilize leverage.

Under the 1940 Act, the Fund is not permitted to issue senior securities if, immediately after the issuance of such senior securities, the Fund would have an asset coverage ratio (as defined in the 1940 Act) of less than 300% with respect to senior securities representing indebtedness or less than 200% with respect to senior securities representing preferred stock. The 1940 Act also provides that the Fund may not declare distributions or purchase its stock (including through tender offers), if immediately after doing so it will have an asset coverage ratio of less than 300% or 200%, as applicable. Under the 1940 Act, certain short-term borrowings (such as for cash management purposes) are not subject to these limitations if (i) repaid within 60 days, (ii) not extended or renewed and (iii) not in excess of 5% of the total assets of the Fund.

In cases where the Fund enters into certain investments (e.g., financial futures contracts, foreign currency exchange contracts and swaps) or certain borrowings (e.g., reverse repurchase agreements) that would be ″senior securities″ for 1940 Act purposes, the Fund may segregate or designate on its books and records cash or liquid assets having a market value at least equal to the amount of the Fund's future obligations under such investments or borrowings. Doing so allows the Fund to not treat the investment or borrowing as a ″senior security.″ Furthermore, if required by an exchange or counterparty agreement, the Fund may deliver/deposit cash and/or securities to/with an exchange, or broker-dealer or custodian as collateral for certain investments or obligations.

Additional information about the Fund's use of leverage is contained in Part I. Additional information about common forms of leverage, such a preferred shares and bank credit facilities, is set forth under Item 10 in this Part II.

II-35

Additional information about common investment instruments and techniques that have the economic effect of leverage, such as reverse repurchase agreements, dollar rolls and derivatives, is set forth elsewhere in this Item 8.

Risk Factors

The NAV of, and dividends paid on, the common shares will fluctuate with and be affected by, among other things, the risks more fully described below.

Offering Risk. The provisions of the 1940 Act generally require that the public offering price of an investment company's common shares (less any underwriting commissions and discounts) must equal or exceed the NAV per share of an investment company's common stock (calculated within 48 hours of pricing). In the offering described in this Prospectus, the Fund may, subject to market conditions, raise additional equity capital by issuing new common shares from time to time in varying amounts at a net price at or above the Fund's NAV per common share (calculated within 48 hours of pricing). To the extent that Fund shares do not trade at a premium, the Fund may be unable to issue additional shares, and may incur costs associated with setting up and maintaining an "at the market" program without the potential benefits. The offering described in this Prospectus may allow the Fund to pursue additional investment opportunities without the need to sell existing portfolio investments and will increase the asset size of the Fund and thus cause the Fund's fixed expenses to be spread over a larger asset base. However, the issuance may not necessarily result in an increase to net income for shareholders, which depends on leverage levels, the comparison between book yields on existing assets, available investment opportunities and other factors. The Fund cannot predict whether its common shares will trade in the future at a premium or discount to their NAV per share. Shares of common stock of closed-end investment companies frequently trade at a discount from NAV, which may increase investors' risk of loss. In no event will shares be issued at a price below the Fund's NAV per common share (calculated within 48 hours of pricing) plus any sales commission charged in connection with the offering.

The offering described in this Prospectus entails potential risks to existing common shareholders. Although the issuance of additional common shares may facilitate a more active market in the Fund's common shares by increasing the amount of common shares outstanding, the issuance of additional common shares may also have an adverse effect on prices for the Fund's common shares in the secondary market by increasing the supply of common shares available for sale. The issuance of additional common shares will dilute the voting power of already outstanding common shares. If the Fund is unable to invest the proceeds of any such offering in a timely manner in assets with a yield at least equal to that of the current portfolio, the Fund's earnings per share may decrease.

Investment and Market Discount Risk. An investment in the Fund's common shares is subject to investment risk, including the possible loss of the entire amount that you invest. As with any stock, the price of the Fund's common shares will fluctuate with market conditions and other factors. If shares are sold, the price received may be more or less than the original investment. The value of your investment in the Fund will be reduced immediately following the offering by the amount of the sales load and the amount of offering expenses paid by the Fund. Common shares are designed for long-term investors and the Fund should not be treated as a trading vehicle. Shares of closed-end management investment companies frequently trade at a discount from their NAV. This risk is separate and distinct from the risk that the Fund's NAV could decrease as a result of its investment activities. At any point in time an investment in the Fund's common shares may be worth less than the original amount invested, even after taking into account distributions paid by the Fund. This risk may be greater for investors who sell their common shares in a relatively short period of time after completion of the initial offering. The Fund uses leverage, which magnifies the Fund's investment, market discount and certain other risks.

Fixed Income Securities Risks. Fixed income securities in which the Fund may invest are generally subject to the following risks:

Interest Rate Risk. The market value of bonds and other fixed-income securities changes in response to interest rate changes and other factors. Interest rate risk is the risk that prices of bonds and other fixed-income securities will increase as interest rates fall and decrease as interest rates rise. The Fund may be subject to a greater risk of rising interest rates due to the current period of historically low interest rates. The magnitude of these fluctuations in the market price of bonds and other fixed-income securities is generally greater for those securities with longer maturities. Fluctuations in the market price of the Fund's investments will not affect interest

II-36

income derived from instruments already owned by the Fund, but will be reflected in the Fund's NAV. The Fund may lose money if short-term or long-term interest rates rise sharply in a manner not anticipated by Fund management. To the extent the Fund invests in debt securities that may be prepaid at the option of the obligor (such as mortgage-related securities), the sensitivity of such securities to changes in interest rates may increase (to the detriment of the Fund) when interest rates rise. Moreover, because rates on certain floating rate debt securities typically reset only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be expected to cause some fluctuations in the NAV of the Fund to the extent that it invests in floating rate debt securities. These basic principles of bond prices also apply to U.S. Government securities. A security backed by the "full faith and credit" of the U.S. Government is guaranteed only as to its stated interest rate and face value at maturity, not its current market price. Just like other fixed-income securities, government-guaranteed securities will fluctuate in value when interest rates change.

The Fund's use of leverage, as described below, will tend to increase the Fund's interest rate risk. The Fund may utilize certain strategies, including taking positions in futures or interest rate swaps, for the purpose of reducing the interest rate sensitivity of fixed income securities held by the Fund and decreasing the Fund's exposure to interest rate risk. The Fund is not required to hedge its exposure to interest rate risk and may choose not to do so. In addition, there is no assurance that any attempts by the Fund to reduce interest rate risk will be successful or that any hedges that the Fund may establish will perfectly correlate with movements in interest rates.

The Fund may invest in variable and floating rate debt instruments, which generally are less sensitive to interest rate changes than longer duration fixed rate instruments, but may decline in value in response to rising interest rates if, for example, the rates at which they pay interest do not rise as much, or as quickly, as market interest rates in general. Conversely, variable and floating rate instruments generally will not increase in value if interest rates decline. The Fund also may invest in inverse floating rate debt securities, which may decrease in value if interest rates increase, and which also may exhibit greater price volatility than fixed rate debt obligations with similar credit quality. To the extent the Fund holds variable or floating rate instruments, a decrease (or, in the case of inverse floating rate securities, an increase) in market interest rates will adversely affect the income received from such securities, which may adversely affect the NAV of the Fund's common shares.

Issuer Risk. The value of fixed income securities may decline for a number of reasons which directly relate to the issuer, such as management performance, financial leverage, reduced demand for the issuer's goods and services, historical and prospective earnings of the issuer and the value of the assets of the issuer.

Credit Risk. Credit risk is the risk that one or more fixed income securities in the Fund's portfolio will decline in price or fail to pay interest or principal when due because the issuer of the security experiences a decline in its financial status. Credit risk is increased when a portfolio security is downgraded or the perceived creditworthiness of the issuer deteriorates. To the extent the Fund invests in below investment grade securities, it will be exposed to a greater amount of credit risk than a fund which only invests in investment grade securities. See "Risk Factors—Below Investment Grade Securities Risk." In addition, to the extent the Fund uses credit derivatives, such use will expose it to additional risk in the event that the bonds underlying the derivatives default. The degree of credit risk depends on the issuer's financial condition and on the terms of the securities.

Prepayment Risk. During periods of declining interest rates, borrowers may exercise their option to prepay principal earlier than scheduled. For fixed rate securities, such payments often occur during periods of declining interest rates, forcing the Fund to reinvest in lower yielding securities, resulting in a possible decline in the Fund's income and distributions to shareholders. This is known as prepayment or "call" risk. Below investment grade securities frequently have call features that allow the issuer to redeem the security at dates prior to its stated maturity at a specified price (typically greater than par) only if certain prescribed conditions are met ("call protection"). For premium bonds (bonds acquired at prices that exceed their par or principal value) purchased by the Fund, prepayment risk may be enhanced.

Reinvestment Risk. Reinvestment risk is the risk that income from the Fund's portfolio will decline if the Fund invests the proceeds from matured, traded or called fixed income securities at market interest rates that are below the Fund portfolio's current earnings rate.

Duration and Maturity Risk. Except as described in Part I, the Fund has no set policy regarding portfolio maturity or duration. The Investment Advisor may seek to adjust the portfolio's duration or maturity based on its

II-37

assessment of current and projected market conditions and all factors that the Investment Advisor deems relevant. Any decisions as to the targeted duration or maturity of any particular category of investments or of the Fund's portfolio generally will be made based on all pertinent market factors at any given time. The Fund may incur costs in seeking to adjust the portfolio average duration or maturity. There can be no assurance that the Investment Advisor's assessment of current and projected market conditions will be correct or that any strategy to adjust the portfolio's duration or maturity will be successful at any given time. Generally speaking, the longer the duration of the Fund's portfolio, the more exposure the Fund will have to the interest rate risks described above.

Senior Loans Risk. Senior loans typically hold the most senior position in the capital structure of the issuing entity, are typically secured with specific collateral and typically have a claim on the assets and/or stock of the borrower that is senior to that held by subordinated debt holders and stockholders of the borrower. The Fund's investments in senior loans are typically below investment grade and are considered speculative because of the credit risk of their issuer. The risks associated with senior loans are similar to the risks of below investment grade fixed income securities, although senior loans are typically senior and secured in contrast to other below investment grade fixed income securities, which are often subordinated and unsecured. See "—Below Investment Grade Securities Risk." Senior loans' higher standing has historically resulted in generally higher recoveries in the event of a corporate reorganization. In addition, because their interest payments are typically adjusted for changes in short-term interest rates, investments in senior loans generally have less interest rate risk than other below investment grade fixed income securities, which may have fixed interest rates.

There is less readily available, reliable information about most senior loans than is the case for many other types of securities. In addition, there is no minimum rating or other independent evaluation of a borrower or its securities limiting the Fund's investments, and the Investment Advisor relies primarily on its own evaluation of a borrower's credit quality rather than on any available independent sources. As a result, the Fund is particularly dependent on the analytical abilities of the Investment Advisor.

The Fund may invest in senior loans rated below investment grade, which are considered speculative because of the credit risk of their issuers. Such companies are more likely to default on their payments of interest and principal owed to the Fund, and such defaults could reduce the Fund's NAV and income distributions. An economic downturn generally leads to a higher non-payment rate and a senior loan may lose significant value before a default occurs. Moreover, any specific collateral used to secure a senior loan may decline in value or become illiquid, which would adversely affect the senior loan's value.

No active trading market may exist for certain senior loans, which may impair the ability of the Fund to realize full value in the event of the need to sell a senior loan and may make it difficult to value senior loans. Adverse market conditions may impair the liquidity of some actively traded senior loans, meaning that the Fund may not be able to sell them quickly at a fair price. To the extent that a secondary market does exist for certain senior loans, the market may be subject to irregular trading activity, wide bid/ask spreads and extended trade settlement periods. Illiquid securities are also difficult to value.

Although the senior loans in which the Fund will invest generally will be secured by specific collateral, there can be no assurance that liquidation of such collateral would satisfy the borrower's obligation in the event of non-payment of scheduled interest or principal or that such collateral could be readily liquidated. In the event of the bankruptcy of a borrower, the Fund could experience delays or limitations with respect to its ability to realize the benefits of the collateral securing a senior loan. If the terms of a senior loan do not require the borrower to pledge additional collateral in the event of a decline in the value of the already pledged collateral, the Fund will be exposed to the risk that the value of the collateral will not at all times equal or exceed the amount of the borrower's obligations under the senior loans. To the extent that a senior loan is collateralized by stock in the borrower or its subsidiaries, such stock may lose all of its value in the event of the bankruptcy of the borrower. Uncollateralized and under-collateralized senior loans involve a greater risk of loss. Some senior loans are subject to the risk that a court, pursuant to fraudulent conveyance or other similar laws, could subordinate the senior loans to presently existing or future indebtedness of the borrower or take other action detrimental to lenders, including the Fund. Such court action could under certain circumstances include invalidation of senior loans.

Senior loans are subject to legislative risk. If legislation or state or federal regulations impose additional requirements or restrictions on the ability of financial institutions to make loans, the availability of senior loans for investment by the Fund may be adversely affected. In addition, such requirements or restrictions could reduce or

II-38

eliminate sources of financing for certain borrowers. This would increase the risk of default. If legislation or federal or state regulations require financial institutions to increase their capital requirements this may cause financial institutions to dispose of senior loans that are considered highly levered transactions. Such sales could result in prices that, in the opinion of the Investment Advisor, do not represent fair value. If the Fund attempts to sell a senior loan at a time when a financial institution is engaging in such a sale, the price the Fund could receive for the senior loan may be adversely affected.

The Fund's investments in senior loans may be subject to lender liability risk. Lender liability refers to a variety of legal theories generally founded on the premise that a lender has violated a duty of good faith, commercial reasonableness and fair dealing or a similar duty owed to the borrower, or has assumed an excessive degree of control over the borrower resulting in the creation of a fiduciary duty owed to the borrower or its other creditors or shareholders. Because of the nature of its investments, the Fund may be subject to allegations of lender liability. In addition, under common law principles that in some cases form the basis for lender liability claims, a court may elect to subordinate the claim of the offending lender or bondholder to the claims of the disadvantaged creditor or creditors.

Second Lien Loans Risk. Second lien loans generally are subject to similar risks as those associated with investments in senior loans. Because second lien loans are subordinated or unsecured and thus lower in priority of payment to senior loans, they are subject to the additional risk that the cash flow of the borrower and property securing the loan or debt, if any, may be insufficient to meet scheduled payments after giving effect to the senior secured obligations of the borrower. This risk is generally higher for subordinated unsecured loans or debt, which are not backed by a security interest in any specific collateral. Second lien loans generally have greater price volatility than senior loans and may be less liquid. Second lien loans share the same risks as other below investment grade securities.

Mezzanine Investment Risk. Mezzanine securities generally are rated below investment grade and frequently are unrated and present many of the same risks as senior loans, second lien loans and non-investment grade bonds. However, unlike senior loans and second lien loans, mezzanine securities are not a senior or secondary secured obligation of the related borrower. They typically are the most subordinated debt obligation in an issuer's capital structure. Mezzanine securities also may often be unsecured. Mezzanine securities therefore are subject to the additional risk that the cash flow of the related borrower and the property securing the loan may be insufficient to repay the scheduled principal after giving effect to any senior obligations of the related borrower. Mezzanine securities are also expected to be a highly illiquid investment. Mezzanine securities will be subject to certain additional risks to the extent that such loans may not be protected by financial covenants or limitations upon additional indebtedness. Investment in mezzanine securities is a highly specialized investment practice that depends more heavily on independent credit analysis than investments in other types of debt obligations.

Risks of Loan Assignments and Participations. The Fund may acquire loan assignments or participations. As the purchaser of an assignment, the Fund typically succeeds to all the rights and obligations of the assigning institution and becomes a lender under the credit agreement with respect to the debt obligation; however, the Fund may not be able to unilaterally enforce all rights and remedies under the loan and with regard to any associated collateral. Because assignments may be arranged through private negotiations between potential assignees and potential assignors, the rights and obligations acquired by the Fund as the purchaser of an assignment may differ from, and be more limited than, those held by the assigning lender. In addition, if the loan is foreclosed, the Fund could become part owner of any collateral and could bear the costs and liabilities of owning and disposing of the collateral. The Fund may be required to pass along to a purchaser that buys a loan from the Fund by way of assignment a portion of any fees to which the Fund is entitled under the loan.

A participation typically results in a contractual relationship only with the institution participating out the interest, not with the borrower. In connection with purchasing participations, the Fund generally will have no right to enforce compliance by the borrower with the terms of the loan agreement relating to the loan, nor any rights of set-off against the borrower, and the Fund may not directly benefit from any collateral supporting the loan in which it has purchased the participation. As a result, the Fund will be subject to the credit risk of both the borrower and the lender that is selling the participation. In the event of the insolvency of the lender selling a participation, the Fund may be treated as a general creditor of the lender and may not benefit from any set-off between the lender and the borrower.

II-39

Bank Loans Risk. The market for bank loans may not be highly liquid and the Fund may have difficulty selling them. These investments are subject to both interest rate risk and credit risk. These investments expose the Fund to the credit risk of both the financial institution and the underlying borrower.

Corporate Bonds Risk. The market value of a corporate bond generally may be expected to rise and fall inversely with interest rates. The market value of intermediate and longer-term corporate bonds is generally more sensitive to changes in interest rates than is the market value of shorter-term corporate bonds. The market value of a corporate bond also may be affected by factors directly related to the issuer, such as investors' perceptions of the creditworthiness of the issuer, the issuer's financial performance, perceptions of the issuer in the market place, performance of management of the issuer, the issuer's capital structure and use of financial leverage and demand for the issuer's goods and services. Certain risks associated with investments in corporate bonds are described elsewhere in this Prospectus in further detail, including under "—Credit Risk," "—Interest Rate Risk," "—Prepayment Risk," "—Inflation Risk" and "—Deflation Risk." There is a risk that the issuers of corporate bonds may not be able to meet their obligations on interest or principal payments at the time called for by an instrument. Corporate bonds of below investment grade quality are often high risk and have speculative characteristics and may be particularly susceptible to adverse issuer-specific developments. Corporate bonds of below investment grade quality are subject to the risks described herein under "—Below Investment Grade Securities Risk."

Below Investment Grade Securities Risk. The Fund may invest in securities that are rated, at the time of investment, below investment grade quality (rated Ba/BB or below, or unrated but judged to be of comparable quality by the Investment Advisor), which are commonly referred to as "high yield" or "junk" bonds and are regarded as predominantly speculative with respect to the issuer's capacity to pay interest and repay principal. The value of high yield, lower quality bonds is affected by the creditworthiness of the issuers of the securities and by general economic and specific industry conditions. Issuers of high yield bonds are not perceived to be as strong financially as those with higher credit ratings. These issuers are more vulnerable to financial setbacks and recession than more creditworthy issuers, which may impair their ability to make interest and principal payments. Lower grade securities may be particularly susceptible to economic downturns. It is likely that an economic recession could disrupt severely the market for such securities and may have an adverse impact on the value of such securities. In addition, it is likely that any such economic downturn could adversely affect the ability of the issuers of such securities to repay principal and pay interest thereon and increase the incidence of default for such securities. See "—Risk Associated with Recent Market Events."

Lower grade securities, though high yielding, are characterized by high risk. They may be subject to certain risks with respect to the issuing entity and to greater market fluctuations than certain lower yielding, higher rated securities. The secondary market for lower grade securities may be less liquid than that for higher rated securities. Adverse conditions could make it difficult at times for the Fund to sell certain securities or could result in lower prices than those used in calculating the Fund's NAV. Because of the substantial risks associated with investments in lower grade securities, you could lose money on your investment in common shares of the Fund, both in the short-term and the long-term.

The prices of fixed income securities generally are inversely related to interest rate changes; however, below investment grade securities historically have been somewhat less sensitive to interest rate changes than higher quality securities of comparable maturity because credit quality is also a significant factor in the valuation of lower grade securities. On the other hand, an increased rate environment results in increased borrowing costs generally, which may impair the credit quality of low-grade issuers and thus have a more significant effect on the value of some lower grade securities. In addition, the current extraordinary low rate environment has expanded the historic universe of buyers of lower grade securities as traditional investment grade oriented investors have been forced to accept more risk in order to maintain income. As rates rise, these recent entrants to the low-grade securities market may exit the market and reduce demand for lower grade securities, potentially resulting in greater price volatility.

rating agency, the Fund's ability to achieve its investment objective will be more dependent on the Investment Advisor' credit analysis than would be the case when the Fund invests in rated securities.

The Fund may invest in securities rated in the lower rating categories (rated Caa1/CCC+ or below, or unrated but judged to be of comparable quality by the Investment Advisor). For these securities, the risks associated with below investment grade instruments are more pronounced. The Fund may, subject to its investment policies, purchase stressed or distressed securities, including securities that are in default or the issuers of which are in bankruptcy, which involve heightened risks. See "—Distressed and Defaulted Securities Risk."

Distressed and Defaulted Securities Risk. Investments in the securities of financially distressed issuers are speculative and involve substantial risks. These securities may present a substantial risk of default or may be in default at the time of investment. The Fund may incur additional expenses to the extent it is required to seek recovery upon a default in the payment of principal or interest on its portfolio holdings. In any reorganization or liquidation proceeding relating to a portfolio company, the Fund may lose its entire investment or may be required to accept cash or securities with a value less than its original investment. Among the risks inherent in investments in a troubled entity is the fact that it frequently may be difficult to obtain information as to the true financial condition of such issuer. The Investment Advisor's judgment about the credit quality of the issuer and the relative value and liquidity of its securities may prove to be wrong. Distressed securities and any securities received in an exchange for such securities may be subject to restrictions on resale.

Yield and Ratings Risk. The yields on certain obligations are dependent on a variety of factors, including general market conditions, conditions in the particular market for the obligation, the financial condition of the issuer, the size of the offering, the maturity of the obligation and the ratings of the issue. The ratings of Moody's and S&P, which are described in Appendix A, represent their respective opinions as to the quality of the obligations they undertake to rate. Ratings, however, are general and are not absolute standards of quality. Consequently, obligations with the same rating, maturity and interest rate may have different market prices. Subsequent to its purchase by the Fund, a rated security may cease to be rated. The Investment Advisor will consider such an event in determining whether the Fund should continue to hold the security.

Unrated Securities Risk. Because the Fund may purchase securities that are not rated by any rating organization, the Investment Advisor may, after assessing their credit quality, internally assign ratings to certain of those securities in categories similar to those of rating organizations. Some unrated securities may not have an active trading market or may be difficult to value, which means the Fund might have difficulty selling them promptly at an acceptable price. To the extent that the Fund invests in unrated securities, the Fund's ability to achieve its investment objective will be more dependent on the Investment Advisor's credit analysis than would be the case when the Fund invests in rated securities.

Debtor-In-Possession (DIP) Financing Risk. The Fund's participation in DIP financings is subject to risks. DIP financings are arranged when an entity seeks the protections of the bankruptcy court under Chapter 11 of the U.S. Bankruptcy Code and must be approved by the bankruptcy court. These financings allow the entity to continue its business operations while reorganizing under Chapter 11. DIP financings are typically fully secured by a lien on the debtor's otherwise unencumbered assets or secured by a junior lien on the debtor's encumbered assets (so long as the loan is fully secured based on the most recent current valuation or appraisal report of the debtor). DIP financings are often required to close with certainty and in a rapid manner in order to satisfy existing creditors and to enable the issuer to emerge from bankruptcy or to avoid a bankruptcy proceeding. There is a risk that the borrower will not emerge from Chapter 11 bankruptcy proceedings and be forced to liquidate its assets under Chapter 7 of the U.S. Bankruptcy Code. In the event of liquidation, the Fund's only recourse will be against the property securing the DIP financing.

Mortgage Related Securities Risks. Investing in MBS entails various risks. MBS represent an interest in a pool of mortgages. The risks associated with MBS include: credit risk associated with the performance of the underlying mortgage properties and of the borrowers owning these properties; risks associated with their structure and execution (including the collateral, the process by which principal and interest payments are allocated and distributed to investors and how credit losses affect the issuing vehicle and the return to investors in such MBS); whether the collateral represents a fixed set of specific assets or accounts, whether the underlying collateral assets are revolving or closed-end, under what terms (including maturity of the MBS) any remaining balance in the accounts may revert to the issuing entity and the extent to which the entity that is the actual source of the collateral

II-41

assets is obligated to provide support to the issuing vehicle or to the investors in such MBS; risks associated with the servicer of the underlying mortgages; adverse changes in economic conditions and circumstances, which are more likely to have an adverse impact on MBS secured by loans on certain types of commercial properties than on those secured by loans on residential properties; prepayment risk, which can lead to significant fluctuations in the value of the MBS; loss of all or part of the premium, if any, paid; and decline in the market value of the security, whether resulting from changes in interest rates, prepayments on the underlying mortgage collateral or perceptions of the credit risk associated with the underlying mortgage collateral. In addition, the Fund's level of investment in MBS of a particular type or in MBS issued or guaranteed by affiliated obligors, serviced by the same servicer or backed by underlying collateral located in a specific geographic region, may subject the Fund to additional risk.

When market interest rates decline, more mortgages are refinanced and the securities are paid off earlier than expected. Prepayments may also occur on a scheduled basis or due to foreclosure. During such periods, the reinvestment of prepayment proceeds by the Fund will generally be at lower rates than the rates that were carried by the obligations that have been prepaid. When market interest rates increase, the market values of MBS decline. At the same time, however, mortgage refinancings and prepayments slow, lengthening the effective maturities of these securities. As a result, the negative effect of the rate increase on the market value of MBS is usually more pronounced than it is for other types of fixed income securities. Moreover, the relationship between borrower prepayments and changes in interest rates may mean some high-yielding MBS and other asset-backed securities have less potential for increases in value if market interest rates were to fall than conventional bonds with comparable maturities.

MBS generally are classified as either RMBS or CMBS, each of which are subject to certain specific risks as further described below.

RMBS Risk. RMBS are securities the payments on which depend primarily on the cash flow from residential mortgage loans made to borrowers that are secured by residential real estate. Non-agency residential mortgage loans are obligations of the borrowers thereunder only and are not typically insured or guaranteed by any other person or entity. The ability of a borrower to repay a loan secured by residential property is dependent upon the income or assets of the borrower. A number of factors, including a general economic downturn, acts of God, terrorism, social unrest and civil disturbances, may impair a borrower's ability to repay its loans.

Agency RMBS Risks. MBS issued by FNMA or FHLMC are guaranteed as to timely payment of principal and interest by FNMA or FHLMC, but are not backed by the full faith and credit of the U.S. Government. In 2008, FHFA placed FNMA and FHLMC into conservatorship. FNMA and FHLMC are continuing to operate as going concerns while in conservatorship and each remains liable for all of its obligations, including its guaranty obligations, associated with its MBS. As the conservator, FHFA succeeded to all rights, titles, powers and privileges of FNMA and FHLMC and of any stockholder, officer or director of FNMA and FHLMC with respect to FNMA and FHLMC and the assets of FNMA and FHLMC. In connection with the conservatorship, the U.S. Treasury entered into an agreement with each of FNMA and FHLMC that contains various covenants that severely limit each enterprise's operations. There is no assurance that the obligations of such entities will be satisfied in full, or that such obligations will not decrease in value or default.

Under the Reform Act, FHFA, as conservator or receiver, has the power to repudiate any contract entered into by FNMA or FHLMC prior to FHFA's appointment as conservator or receiver, as

II-42

applicable, if FHFA determines, in its sole discretion, that performance of the contract is burdensome and that repudiation of the contract promotes the orderly administration of FNMA's or FHLMC's affairs. In the event that FHFA, as conservator or if it is later appointed as receiver for FNMA or FHLMC, were to repudiate any such guaranty obligation, the conservatorship or receivership estate, as applicable, would be liable for actual direct compensatory damages in accordance with the provisions of the Reform Act. Any such liability could be satisfied only to the extent of FNMA's or FHLMC's assets available therefor. In the event of repudiation, the payments of interest to holders of FNMA or FHLMC MBS would be reduced if payments on the mortgage loans represented in the mortgage loan groups related to such MBS are not made by the borrowers or advanced by the servicer. Any actual direct compensatory damages for repudiating these guaranty obligations may not be sufficient to offset any shortfalls experienced by such mortgage-backed security holders. Further, in its capacity as conservator or receiver, FHFA has the right to transfer or sell any asset or liability of FNMA or FHLMC without any approval, assignment or consent. If FHFA, as conservator or receiver, were to transfer any such guaranty obligation to another party, holders of FNMA or FHLMC MBS would have to rely on that party for satisfaction of the guaranty obligation and would be exposed to the credit risk of that party. In addition, certain rights provided to holders of MBS issued by FNMA and FHLMC under the operative documents related to such securities may not be enforced against FHFA, or enforcement of such rights may be delayed, during the conservatorship or any future receivership. The operative documents for FNMA and FHLMC MBS may provide (or with respect to securities issued prior to the date of the appointment of the conservator may have provided) that upon the occurrence of an event of default on the part of FNMA or FHLMC, in its capacity as guarantor, which includes the appointment of a conservator or receiver, holders of such MBS have the right to replace FNMA or FHLMC as trustee if the requisite percentage of MBS holders consent. The Reform Act prevents mortgage-backed security holders from enforcing such rights if the event of default arises solely because a conservator or receiver has been appointed.

A 2011 report to Congress from the Treasury Department and the Department of Housing and Urban Development set forth a plan to reform America's housing finance market, which would reduce the role of and eventually eliminate FNMA and FHLMC, and identified proposals for Congress and the administration to consider for the long-term structure of the housing finance markets after the elimination of FNMA and FHLMC. The impact of such reforms on the markets for MBS is currently unknown. It is difficult, if not impossible, to predict the future political, regulatory or economic changes that could impact FNMA, FHLMC and the FHLBs, and the values of their related securities or obligations.

Non-Agency RMBS Risks. Non-agency RMBS are securities issued by non-governmental issuers. Non-agency RMBS have no direct or indirect government guarantees of payment and are subject to various risks as described herein.

Borrower Credit Risk. Credit-related risk on RMBS arises from losses due to delinquencies and defaults by the borrowers in payments on the underlying mortgage loans and breaches by originators and servicers of their obligations under the underlying documentation pursuant to which the RMBS are issued. Non-agency residential mortgage loans are obligations of the borrowers thereunder only and are not typically insured or guaranteed by any other person or entity. The rate of delinquencies and defaults on residential mortgage loans and the aggregate amount of the resulting losses will be affected by a number of factors, including general economic conditions, particularly those in the area where the related mortgaged property is located, the level of the borrower's equity in the mortgaged property and the individual financial circumstances of the borrower. If a residential mortgage loan is in default, foreclosure on the related residential property may be a lengthy and difficult process involving significant legal and other expenses. The net proceeds obtained by the holder on a residential mortgage loan following the foreclosure on the related property may be less than the total amount that remains due on the loan. The prospect of incurring a loss upon the foreclosure of the related property may lead the holder of the residential mortgage loan to restructure the residential mortgage loan or otherwise delay the foreclosure process.

II-43

Legal Risks. Legal risks associated with RMBS can arise as a result of the procedures followed in connection with the origination of the mortgage loans or the servicing thereof, which may be subject to various federal and state laws (including, without limitation, predatory lending laws), public policies and principles of equity that regulate interest rates and other charges, require certain disclosures, require licensing of originators, prohibit discriminatory lending practices, regulate the use of consumer credit information and debt collection practices and may limit the servicer's ability to collect all or part of the principal of or interest on a residential mortgage loan, entitle the borrower to a refund of amounts previously paid by it or subject the servicer to damages and sanctions. Specifically, provisions of federal predatory lending laws, such as the federal Truth-in-Lending Act (as supplemented by the Home Ownership and Equity Protection Act of 1994) and Regulation Z, and various recently enacted state predatory lending laws provide that a purchaser or assignee of specified types of residential mortgage loans (including an issuer of RMBS) may be held liable for violations by the originator of such mortgage loans. Under such assignee liability provisions, a borrower is generally given the right to assert against a purchaser of its mortgage loan any affirmative claims and defenses to payment that such borrower could assert against the originator of the loan or, where applicable, the home improvement contractor that arranged the loan. Liability under such assignee liability provisions could, therefore, result in a disruption of cash flows allocated to the holders of RMBS where either the issuer of such RMBS is liable for damages or is unable to enforce payment by the borrower.

In most but not all cases, the amount recoverable against a purchaser or assignee under such assignee liability provisions is limited to amounts previously paid and still owed by the borrower. Moreover, sellers of residential mortgage loans to an issuer of RMBS typically represent that the loans have been originated in accordance with all applicable laws and in the event such representation is breached, the seller typically must repurchase the offending loan. Notwithstanding these protections, an issuer of RMBS may be exposed to an unquantifiable amount of potential assignee liability because, first, the amount of potential assignee liability under certain predatory lending laws is unclear and has yet to be litigated, and, second, in the event a predatory lending law does not prohibit class action lawsuits, it is possible that an issuer of RMBS could be liable for damages for more than the original principal amount of the offending loans held by it. In such circumstances the issuer of RMBS may be forced to seek contribution from other parties, who may no longer exist or have adequate funds available to fund such contribution.

In addition, structural and legal risks of RMBS include the possibility that, in a bankruptcy or similar proceeding involving the originator or the servicer (often the same entity or affiliates), the assets of the issuer could be treated as never having been truly sold by the originator to the issuer and could be substantively consolidated with those of the originator, or the transfer of such assets to the issuer could be voided as a fraudulent transfer. Challenges based on such doctrines could result also in cash flow delays and losses on the related issue of RMBS.

Mortgage Loan Market Risk. In the recent past, the residential mortgage market in the United States experienced difficulties that adversely affected the performance and market value of certain mortgages and mortgage related securities. Delinquencies and losses on residential mortgage loans (especially sub-prime and second lien mortgage loans) generally increased during this period and declines in or flattening of housing values in many housing markets were generally viewed as exacerbating such delinquencies and losses. Borrowers with ARMs are more sensitive to changes in interest rates, which affect their monthly mortgage payments, and may be unable to secure replacement mortgages at comparably low interest rates.

At any one time, a portfolio of RMBS may be backed by residential mortgage loans that are highly concentrated in only a few states or regions. As a result, the performance of such residential mortgage loans may be more susceptible to a downturn in the economy, including in particular industries that are highly represented in such states or regions, natural calamities and other adverse conditions affecting such areas. The economic downturn experienced in the recent past at the national level, and the more serious economic downturn experienced in the recent past in certain

II-44

geographic areas of the United States, including in particular areas of the United States where rates of delinquencies and defaults on residential mortgage loans were particularly high, is generally viewed as having contributed to the higher rates of delinquencies and defaults on the residential mortgage loans underlying RMBS during this period. There also can be no assurance that areas of the United States that mostly avoided higher rates of delinquencies and defaults on residential mortgage loans during this period would continue to do so if an economic downturn were to reoccur at the national level.

Another factor that may contribute to, and may in the future result in, higher delinquency and default rates is the increase in monthly payments on ARMs. Any increase in prevailing market interest rates, which are currently near historical lows, may result in increased payments for borrowers who have ARMs. Moreover, with respect to hybrid mortgage loans (which are mortgage loans combining fixed and adjustable rate features) after their initial fixed rate period or other adjustable-rate mortgage loans, interest-only products or products having a lower rate, and with respect to mortgage loans with a negative amortization feature which reach their negative amortization cap, borrowers may experience a substantial increase in their monthly payment even without an increase in prevailing market interest rates. Increases in payments for borrowers may result in increased rates of delinquencies and defaults on residential mortgage loans underlying the non-agency RMBS.

As a result of rising concerns about increases in delinquencies and defaults on residential mortgage loans (particularly on sub-prime and adjustable-rate mortgage loans) and as a result of increasing concerns about the financial strength of originators and servicers and their ability to perform their obligations with respect to non-agency RMBS, there may be an adverse change in the market sentiments of investors about the market values and volatility and the degree of risk of non-agency RMBS generally. Some or all of the underlying residential mortgage loans in an issue of non-agency RMBS may have balloon payments due on their respective maturity dates. Balloon residential mortgage loans involve a greater risk to a lender than fully amortizing loans, because the ability of a borrower to pay such amount will normally depend on its ability to obtain refinancing of the related mortgage loan or sell the related mortgaged property at a price sufficient to permit the borrower to make the balloon payment, which will depend on a number of factors prevailing at the time such refinancing or sale is required, including, without limitation, the strength of the local or national residential real estate markets, interest rates and general economic conditions and the financial condition of the borrower. If borrowers are unable to make such balloon payments, the related issue of non-agency RMBS may experience losses.

The Fund may acquire RMBS backed by collateral pools of mortgage loans that have been originated using underwriting standards that are less restrictive than those used in underwriting "prime mortgage loans" and "Alt-A mortgage loans." These lower standards include mortgage loans made to borrowers having imperfect or impaired credit histories, mortgage loans where the amount of the loan at origination is 80% or more of the value of the mortgage property, mortgage loans made to borrowers with low credit scores, mortgage loans made to borrowers who have other debt that represents a large portion of their income and mortgage loans made to borrowers whose income is not required to be disclosed or verified and are commonly referred to as "sub-prime" mortgage loans. Sub-prime mortgage loans have in recent periods experienced increased rates of delinquency, foreclosure, bankruptcy and loss, and they are likely to continue to experience delinquency, foreclosure, bankruptcy and loss rates that are higher, and that may be substantially higher, than those experienced by mortgage loans underwritten in a more traditional manner. Certain categories of RMBS, such as option ARM RMBS and sub-prime RMBS, have been referred to by the financial media as "toxic assets."

Although the United States economy has been slowly improving in recent years, if the economy of the United States begins to deteriorate again the incidence of mortgage foreclosures, especially sub-prime mortgages, could begin to increase again, which could adversely affect the value of any RMBS owned by the Fund.

II-45

Legislation and Regulation Risk. The significance of the mortgage crisis and loan defaults in residential mortgage loan sectors led to the enactment in July 2008 of the Housing and Economic Recovery Act of 2008, a wide-ranging housing rescue bill that offers up to $300 billion in assistance to troubled homeowners and emergency assistance to FNMA and FHLMC. This bill could potentially have a material adverse effect on the Fund's investment program as the bill, among other things, (1) allows approximately 400,000 homeowners to refinance into affordable, government-backed loans through a program run by the FHA, and (2) provides approximately $180 million for "pre-foreclosure" housing counseling and legal services for distressed borrowers. In 2007, U.S. Treasury then-Secretary Henry Paulson and HUD then-Secretary Alphonso Jackson and the mortgage industry worked to develop HOPE NOW, an alliance of participants in the mortgage industry intended to work with borrowers with sub-prime mortgages facing interest rate increases and increasing payments. The Congressional Research Service reports that HOPE NOW has undertaken an initiative to provide homeowners with free telephone consultations with HUD-approved credit counselors, who can help homeowners contact their lenders and credit counselors to work out a plan to avoid foreclosure. Certain borrowers may also seek relief through the "FHA Secure" refinancing option that gives homeowners with non-FHA ARMs, current or delinquent and regardless of reset status, the ability to refinance into a FHA-insured mortgage. The Helping Families Save Their Homes Act of 2009, which was enacted on May 20, 2009, provides a safe harbor for servicers entering into "qualified loss mitigation plans" with respect to residential mortgages originated before the act was enacted. By protecting servicers from certain liabilities, this safe harbor may encourage loan modifications and reduce the likelihood that investors in securitizations will be paid on a timely basis or will be paid in full.

In addition, the mortgage crisis has led public advocacy groups to demand, and governmental officials and federal and state regulatory agencies to propose and consider, a variety of other "bailout" and "rescue" plans that could potentially have a material adverse effect on the Fund's investment program. Some members of the U.S. Congress are concerned that the downturn in the housing market has played a role in the rise of late mortgage payments and foreclosures and expect that these conditions will lead to increased filings for bankruptcy. The terms of other proposed legislation or other plans may include, by way of example and not limitation, the following:

moratoriums on interest rate increases for certain mortgage loans and on foreclosure proceedings;

conversions of ARMs to fixed-rate mortgages (including in connection with government-backed refinancings of individual mortgage loans), with potential workouts to provide borrowers with equity stakes in their homes;

increased scrutiny of mortgage originations (including mortgage loans in which the Fund may own an interest through non-agency RMBS) and foreclosure proceedings;

additional registration and licensing requirements for mortgage brokers, lenders and others involved in the mortgage industry; and

greater relief to homeowners under the U.S. Bankruptcy Code or other federal or state laws, including relief to stay or delay the foreclosure of residential mortgage loans or to modify payment terms, including interest rates and repayment periods, of residential mortgage loans, over a lender's objections, as the result of a "cramdown," which decreases the debt's value to as low as the collateral's fair market value.

A significant number of loan modifications could result in a significant reduction in cash flows to the holders of the mortgage securities on an ongoing basis. These loan modification programs, as well as future legislative or regulatory actions, including amendments to the bankruptcy laws, that result in the modification of outstanding mortgage loans may adversely affect the value of, and the returns on, the assets in which the Fund may invest.

II-46

New laws, legislation or other government regulations, including those promulgated in furtherance of a "bailout" or "rescue" plan to address the crisis and distress in the residential mortgage loan sector, may result in a reduction of available transactional opportunities for the Fund, or an increase in the cost associated with such transactions. Any such law, legislation or regulation may adversely affect the market value of RMBS.

CMBS Risk. CMBS are, generally, securities backed by obligations (including certificates of participation in obligations) that are principally secured by mortgages on real property or interests therein having a multifamily or commercial use, such as regional malls, other retail space, office buildings, industrial or warehouse properties, hotels, nursing homes and senior living centers. The market for CMBS developed more recently and, in terms of total outstanding principal amount of issues, is relatively small compared to the market for single-family RMBS. CMBS are subject to particular risks, including lack of standardized terms, shorter maturities than residential mortgage loans and payment of all or substantially all of the principal only at maturity rather than regular amortization of principal. Additional risks may be presented by the type and use of a particular commercial property. Special risks are presented by hospitals, nursing homes, hospitality properties and certain other property types. Commercial property values and net operating income are subject to volatility, which may result in net operating income becoming insufficient to cover debt service on the related mortgage loan. The repayment of loans secured by income-producing properties is typically dependent upon the successful operation of the related real estate project rather than upon the liquidation value of the underlying real estate. Furthermore, the net operating income from and value of any commercial property is subject to various risks, including changes in general or local economic conditions and/or specific industry segments; the solvency of the related tenants; declines in real estate values; declines in rental or occupancy rates; increases in interest rates, real estate tax rates and other operating expenses; changes in governmental rules, regulations and fiscal policies; acts of God; terrorist threats and attacks and social unrest and civil disturbances. Consequently, adverse changes in economic conditions and circumstances are more likely to have an adverse impact on MBS secured by loans on commercial properties than on those secured by loans on residential properties. In addition, commercial lending generally is viewed as exposing the lender to a greater risk of loss than one- to four- family residential lending. Commercial lending, for example, typically involves larger loans to single borrowers or groups of related borrowers than residential one- to four- family mortgage loans. In addition, the repayment of loans secured by income producing properties typically is dependent upon the successful operation of the related real estate project and the cash flow generated therefrom.

The exercise of remedies and successful realization of liquidation proceeds relating to CMBS is also highly dependent on the performance of the servicer or special servicer. In many cases, overall control over the special servicing of related underlying mortgage loans will be held by a "directing certificateholder" or a "controlling class representative," which is appointed by the holders of the most subordinate class of CMBS in such series. The Fund may not have the right to appoint the directing certificateholder. In connection with the servicing of the specially serviced mortgage loans, the related special servicer may, at the direction of the directing certificateholder, take actions with respect to the specially serviced mortgage loans that could adversely affect the Fund's interests. There may be a limited number of special servicers available, particularly those that do not have conflicts of interest.

The Fund may invest in Subordinated CMBS issued or sponsored by commercial banks, savings and loan institutions, mortgage bankers, private mortgage insurance companies and other non-governmental issuers. Subordinated CMBS have no governmental guarantee and are subordinated in some manner as to the payment of principal and/or interest to the holders of more senior CMBS arising out of the same pool of mortgages. Subordinated CMBS are often referred to as "B-Pieces." The holders of Subordinated CMBS typically are compensated with a higher stated yield than are the holders of more senior CMBS. On the other hand, Subordinated CMBS typically subject the holder to greater risk than senior CMBS and tend to be rated in a lower rating category (frequently a substantially lower rating category) than the senior CMBS issued in respect of the same mortgage pool. Subordinated CMBS generally are likely to be more sensitive to changes in prepayment and interest rates and the market for such securities may be less liquid than is the case for traditional income securities and senior CMBS.

Credit Risk Associated with Originators and Servicers of Mortgage Loans. A number of originators and servicers of residential and commercial mortgage loans, including some of the largest originators and servicers in the residential and commercial mortgage loan market, have experienced serious financial difficulties, including some that are now or were subject to federal insolvency proceedings. These difficulties have resulted from many factors, including increased competition among originators for borrowers, decreased originations by such originators of

II-47

mortgage loans and increased delinquencies and defaults on such mortgage loans, as well as from increases in claims for repurchases of mortgage loans previously sold by them under agreements that require repurchase in the event of breaches of representations regarding loan quality and characteristics. Such difficulties may affect the performance of MBS backed by mortgage loans. Furthermore, the inability of the originator to repurchase such mortgage loans in the event of loan representation breaches or the servicer to repurchase such mortgage loans upon a breach of its servicing obligations also may affect the performance of related MBS. Delinquencies and losses on, and, in some cases, claims for repurchase by the originator of, mortgage loans originated by some mortgage lenders have recently increased as a result of inadequate underwriting procedures and policies, including inadequate due diligence, failure to comply with predatory and other lending laws and, particularly in the case of any "no documentation" or "limited documentation" mortgage loans that may support non-agency RMBS, inadequate verification of income and employment history. Delinquencies and losses on, and claims for repurchase of, mortgage loans originated by some mortgage lenders have also resulted from fraudulent activities of borrowers, lenders, appraisers, and other residential mortgage industry participants such as mortgage brokers, including misstatements of income and employment history, identity theft and overstatements of the appraised value of mortgaged properties. Many of these originators and servicers are very highly leveraged. These difficulties may also increase the chances that these entities may default on their warehousing or other credit lines or become insolvent or bankrupt and thereby increase the likelihood that repurchase obligations will not be fulfilled and the potential for loss to holders of non-agency MBS and subordinated security holders.

The servicers of non-agency MBS are often the same entities as, or affiliates of, the originators of these mortgage loans. Accordingly, the financial risks relating to originators of MBS described immediately above also may affect the servicing of MBS. In the case of such servicers, and other servicers, financial difficulties may have a negative effect on the ability of servicers to pursue collection on mortgage loans that are experiencing increased delinquencies and defaults and to maximize recoveries on sale of underlying properties following foreclosure. In recent years, a number of lenders specializing in residential mortgages have sought bankruptcy protection, shut down or been refused further financings from their lenders.

MBS typically provide that the servicer is required to make advances in respect of delinquent mortgage loans. However, servicers experiencing financial difficulties may not be able to perform these obligations or obligations that they may have to other parties of transactions involving these securities. Like originators, these entities are typically very highly leveraged. Such difficulties may cause servicers to default under their financing arrangements. In certain cases, such entities may be forced to seek bankruptcy protection. Due to the application of the provisions of bankruptcy law, servicers who have sought bankruptcy protection may not be required to advance such amounts. Even if a servicer were able to advance amounts in respect of delinquent mortgage loans, its obligation to make such advances may be limited to the extent that it does not expect to recover such advances due to the deteriorating credit of the delinquent mortgage loans or declining value of the related mortgaged properties. Moreover, servicers may overadvance against a particular mortgage loan or charge too many costs of resolution or foreclosure of a mortgage loan to a securitization, which could increase the potential losses to holders of MBS. In such transactions, a servicer's obligation to make such advances may also be limited to the amount of its servicing fee. In addition, if an issue of MBS provides for interest on advances made by the servicer, in the event that foreclosure proceeds or payments by borrowers are not sufficient to cover such interest, such interest will be paid to the servicer from available collections or other mortgage income, thereby reducing distributions made on the MBS and, in the case of senior-subordinated MBS described below, first from distributions that would otherwise be made on the most subordinated MBS of such issue. Any such financial difficulties may increase the possibility of a servicer termination and the need for a transfer of servicing and any such liabilities or inability to assess such liabilities may increase the difficulties and costs in affecting such transfer and the potential loss, through the allocation of such increased cost of such transfer, to subordinated security holders.

There can be no assurance that originators and servicers of mortgage loans will not continue to experience serious financial difficulties or experience such difficulties in the future, including becoming subject to bankruptcy or insolvency proceedings, or that underwriting procedures and policies and protections against fraud will be sufficient in the future to prevent such financial difficulties or significant levels of default or delinquency on mortgage loans. Because the recent financial difficulties experienced by such originators and servicers is unprecedented and unpredictable, the past performance of the residential and commercial mortgage loans originated and serviced by them (and the corresponding performance of the related MBS) is not a reliable indicator of the future performance of such residential mortgage loans (or the related MBS).

II-48

In some cases, servicers of MBS have been the subject of legal proceedings involving the origination and/or servicing practices of such servicers. Large groups of private litigants and states' attorneys general have brought such proceedings. Because of the large volume of mortgage loans originated and serviced by such servicers, such litigation can cause heightened financial strain on servicers. In other cases, origination and servicing practices may cause or contribute to such strain, because of representation and warranty repurchase liability arising in MBS and mortgage loan sale transactions. Any such financial strain could cause servicers to service below required standards, causing delinquencies and losses in any related MBS transaction to rise, and in extreme cases could cause the servicer to seek the protection of any applicable bankruptcy or insolvency law. In any such proceeding, it is unclear whether the fees that the servicer charges in such transactions would be sufficient to permit that servicer or a successor servicer to service the mortgage loans in such transaction adequately. If such fees had to be increased, it is likely that the most subordinated security holders in such transactions would be effectively required to pay such increased fees. Finally, these entities may be the subject of future laws designed to protect consumers from defaulting on their mortgage loans. Such laws may have an adverse effect on the cash flows paid under such MBS.

In addition, certain lenders who service and/or issue MBS have recently announced that they are being investigated by or have received information requests from U.S. federal and/or state authorities, including the SEC. As a result of such investigations and other similar investigations and general concerns about the adequacy or accuracy of disclosure of risks to borrowers and their understanding of such risks, U.S. financial regulators have recently indicated that they may propose new guidelines for the mortgage industry. Guidelines, if introduced, together with the other factors described herein, may make it more difficult for borrowers with weaker credit to refinance, which may lead to further increases in delinquencies, extensions in duration and losses in mortgage related assets.

Adjustable Rate Mortgage Risk. ARMs contain maximum and minimum rates beyond which the mortgage interest rate may not vary over the lifetime of the security. In addition, many ARMs provide for additional limitations on the maximum amount by which the mortgage interest rate may adjust for any single adjustment period. Alternatively, certain ARMs contain limitations on changes in the required monthly payment. In the event that a monthly payment is not sufficient to pay the interest accruing on an ARM, any excess interest is added to the principal balance of the mortgage loan, which is repaid through future monthly payments. If the monthly payment for such an instrument exceeds the sum of the interest accrued at the applicable mortgage interest rate and the principal payment required at such point to amortize the outstanding principal balance over the remaining term of the loan, the excess is used to reduce the then-outstanding principal balance of the ARM.

In addition, certain ARMs may provide for an initial fixed, below-market or "teaser" interest rate. During this initial fixed rate period, the payment due from the related mortgagor may be less than that of a traditional loan. However, after the "teaser" rate expires, the monthly payment required to be made by the mortgagor may increase dramatically when the interest rate on the mortgage loan adjusts. This increased burden on the mortgagor may increase the risk of delinquency or default on the mortgage loan and in turn, losses on the MBS into which that loan has been bundled. This risk may be increased as increases in prevailing market interest rates, which are currently near historical lows, may result in increased payments for borrowers with ARMs.

Stripped MBS Risk. Stripped MBS may be subject to additional risks. One type of stripped MBS pays to one class all of the interest from the mortgage assets (the "IO class"), while the other class will receive all of the principal (the "PO class"). The yield to maturity on an IO class is extremely sensitive to the rate of principal payments (including prepayments) on the underlying mortgage assets and a rapid rate of principal payments may have a material adverse effect on the Fund's yield to maturity from these securities. If the assets underlying the IO class experience greater than anticipated prepayments of principal, the Fund may fail to recoup fully, or at all, its initial investment in these securities. Conversely, PO class securities tend to decline in value if prepayments are slower than anticipated.

CMO Risk. There are certain risks associated specifically with CMOs. CMOs are debt obligations collateralized by mortgage loans or mortgage pass-through securities. The average life of a CMO is determined using mathematical models that incorporate prepayment assumptions and other factors that involve estimates of future economic and market conditions. Actual future results may vary from these estimates, particularly during periods of extreme market volatility. Further, under certain market conditions, such as those that occurred during the recent downturn in the mortgage markets, the weighted average life of certain CMOs may not accurately reflect the price volatility of such securities. For example, in periods of supply and demand imbalances in the market for such

II-49

securities and/or in periods of sharp interest rate movements, the prices of CMOs may fluctuate to a greater extent than would be expected from interest rate movements alone. CMOs issued by private entities are not obligations issued or guaranteed by the U.S. Government, its agencies or instrumentalities and are not guaranteed by any government agency, although the securities underlying a CMO may be subject to a guarantee. Therefore, if the collateral securing the CMO, as well as any third party credit support or guarantees, is insufficient to make payments when due, the holder could sustain a loss.

Inverse floating rate CMOs are typically more volatile than fixed or floating rate tranches of CMOs. Many inverse floating rate CMOs have coupons that move inversely to a multiple of an index. The effect of the coupon varying inversely to a multiple of an applicable index creates a leverage factor. Inverse floaters based on multiples of a stated index are designed to be highly sensitive to changes in interest rates and can subject the holders thereof to extreme reductions of yield and loss of principal. The market for inverse floating rate CMOs with highly leveraged characteristics at times may be very thin. The Fund's ability to dispose of its positions in such securities will depend on the degree of liquidity in the markets for such securities. It is impossible to predict the amount of trading interest that may exist in such securities, and therefore the future degree of liquidity.

The Fund may also invest in REMICs, which are CMOs that qualify for special tax treatment under the Code and invest in certain mortgages principally secured by interests in real property and other permitted investments.

Additional Risks of Mortgage Related Securities. Additional risks associated with investments in MBS include:

Interest Rate Risk. In addition to the interest rate risks described under "Risk Factors—Interest Rate Risk," certain MBS may be subject to additional risks as the rate of interest payable on certain MBS may be set or effectively capped at the weighted average net coupon of the underlying mortgage loans themselves, often referred to as an "available funds cap." As a result of this cap, the return to the holder of such MBS is dependent on the relative timing and rate of delinquencies and prepayments of mortgage loans bearing a higher rate of interest. In general, early prepayments will have a greater negative impact on the yield to the holder of such MBS.

Structural Risk. Because MBS generally are ownership or participation interests in pools of mortgage loans secured by a pool of properties underlying the mortgage loan pool, the MBS are entitled to payments provided for in the underlying agreement only when and if funds are generated by the underlying mortgage loan pool. This likelihood of the return of interest and principal may be assessed as a credit matter. However, the holders of MBS do not have the legal status of secured creditors, and cannot accelerate a claim for payment on their securities, or force a sale of the mortgage loan pool in the event that insufficient funds exist to pay such amounts on any date designated for such payment. The holders of MBS do not typically have any right to remove a servicer solely as a result of a failure of the mortgage pool to perform as expected.

Subordination Risk. MBS may be subordinated to one or more other senior classes of securities of the same series for purposes of, among other things, offsetting losses and other shortfalls with respect to the related underlying mortgage loans. For example, in the case of certain MBS, no distributions of principal will generally be made with respect to any class until the aggregate principal balances of the corresponding senior classes of securities have been reduced to zero. As a result, MBS may be more sensitive to risk of loss, writedowns, the non-fulfillment of repurchase obligations, overadvancing on a pool of loans and the costs of transferring servicing than senior classes of securities.

Prepayment, Extension and Redemption Risks. MBS may reflect an interest in monthly payments made by the borrowers who receive the underlying mortgage loans. Although the underlying mortgage loans are for specified periods of time, such as 20 or 30 years, the borrowers can, and historically have paid them off sooner. When a prepayment happens, a portion of the MBS which represents an interest in the underlying mortgage loan will be prepaid. A borrower is more likely to prepay a mortgage which bears a relatively high rate of interest. This means that in times of declining interest rates, a portion of the Fund's higher yielding securities are likely to be

II-50

redeemed and the Fund will probably be unable to replace them with securities having as great a yield. In addition to reductions in the level of market interest rates and the prepayment provisions of the mortgage loans, repayments on the residential mortgage loans underlying an issue of RMBS may also be affected by a variety of economic, geographic and other factors, including the size difference between the interest rates on the underlying residential mortgage loans (giving consideration to the cost of refinancing) and prevailing mortgage rates and the availability of refinancing. Prepayments can result in lower yields to shareholders. The increased likelihood of prepayment when interest rates decline also limits market price appreciation of MBS. This is known as prepayment risk.

Except in the case of certain types of RMBS, the mortgage loans underlying RMBS generally do not contain prepayment penalties and a reduction in market interest rates will increase the likelihood of prepayments on the related RMBS. In the case of certain home equity loan securities and certain types of RMBS, even though the underlying mortgage loans often contain prepayment premiums, such prepayment premiums may not be sufficient to discourage borrowers from prepaying their mortgage loans in the event of a reduction in market interest rates, resulting in a reduction in the yield to maturity for holders of the related RMBS. RMBS typically contain provisions that require repurchase of mortgage loans by the originator or other seller in the event of a breach of a representation or warranty regarding loan quality and characteristics of such loan. Any repurchase of a mortgage loan as a result of a breach has the same effect on the yield received on the related issue of RMBS as a prepayment of such mortgage loan. Any increase in breaches of representations and the consequent repurchases of mortgage loans that result from inadequate underwriting procedures and policies and protections against fraud will have the same effect on the yield on the related RMBS as an increase in prepayment rates.

Risk of prepayment may be reduced for commercial real estate property loans containing significant prepayment penalties or prohibitions on principal payments for a period of time following origination.

MBS also are subject to extension risk. Extension risk is the possibility that rising interest rates may cause prepayments to occur at a slower than expected rate. This particular risk may effectively change a security which was considered short or intermediate term into a long-term security. The values of long-term securities generally fluctuate more widely in response to changes in interest rates than short or intermediate-term securities.

In addition, MBS may be subject to redemption at the option of the issuer. If a MBS held by the Fund is called for redemption, the Fund will be required to permit the issuer to redeem or "pay-off" the security, which could have an adverse effect on the Fund's ability to achieve its investment objective.

Spread Widening Risk. The prices of MBS may decline substantially, for reasons that may not be attributable to any of the other risks described in this Prospectus. In particular, purchasing assets at what may appear to be "undervalued" levels is no guarantee that these assets will not be trading at even more "undervalued" levels at a time of valuation or at the time of sale. It may not be possible to predict, or to protect against, such "spread widening" risk.

Liquidity Risk. The liquidity of MBS varies by type of security; at certain times the Fund may encounter difficulty in disposing of such investments. Because MBS have the potential to be less liquid than other securities, the Fund may be more susceptible to liquidity risks than funds that invest in other securities. In the past, in stressed markets, certain types of MBS suffered periods of illiquidity when disfavored by the market. Due to increased instability in the credit markets, the market for some MBS has experienced reduced liquidity and greater volatility with respect to the value of such securities, making it more difficult to value such securities.

ABS Risk. ABS involve certain risks in addition to those presented by MBS. There is the possibility that recoveries on the underlying collateral may not, in some cases, be available to support payments on these securities. Relative to MBS, ABS may provide the Fund with a less effective security interest in the underlying collateral and

II-51

are more dependent on the borrower's ability to pay. If many borrowers on the underlying loans default, losses could exceed the credit enhancement level and result in losses to investors in an ABS transaction. Finally, ABS have structure risk due to a unique characteristic known as early amortization, or early payout, risk. Built into the structure of most ABS are triggers for early payout, designed to protect investors from losses. These triggers are unique to each transaction and can include a significant rise in defaults on the underlying loans, a sharp drop in the credit enhancement level or the bankruptcy of the originator. Once early amortization begins, all incoming loan payments (after expenses are paid) are used to pay investors as quickly as possible based upon a predetermined priority of payment.

The collateral underlying ABS may constitute assets related to a wide range of industries and sectors, such as credit card and automobile receivables. Credit card receivables are generally unsecured and the debtors are entitled to the protection of a number of state and federal consumer credit laws, many of which give debtors the right to set off certain amounts owed on the credit cards, thereby reducing the balance due. The Credit CARD Act of 2009 imposes new regulations on the ability of credit card issuers to adjust the interest rates and exercise various other rights with respect to indebtedness extended through credit cards. The Fund and the Investment Advisor cannot predict what effect, if any, such regulations might have on the market for ABS and such regulations may adversely affect the value of ABS owned by the Fund. Most issuers of automobile receivables permit the servicers to retain possession of the underlying obligations. If the servicer were to sell these obligations to another party, there is a risk that the purchaser would acquire an interest superior to that of the holders of the related automobile receivables. In addition, because of the large number of vehicles involved in a typical issuance and technical requirements under state laws, the trustee for the holders of the automobile receivables may not have an effective security interest in all of the obligations backing such receivables. If the economy of the United States deteriorates, defaults on securities backed by credit card, automobile and other receivables may increase, which may adversely affect the value of any ABS owned by the Fund. There is the possibility that recoveries on the underlying collateral may not, in some cases, be available to support payments on these securities. In recent years, certain automobile manufacturers have been granted access to emergency loans from the U.S. Government and have experienced bankruptcy. As a result of these events, the value of securities backed by receivables from the sale or lease of automobiles may be adversely affected.

Some ABS, particularly home equity loan transactions, are subject to interest rate risk and prepayment risk. A change in interest rates can affect the pace of payments on the underlying loans, which in turn, affects total return on the securities.

CDO Risks. In addition to the general risks associated with fixed income securities discussed herein, CDOs carry additional risks, including: (i) the possibility that distributions from collateral securities will not be adequate to make interest or other payments; (ii) the quality of the collateral may decline in value or default; (iii) the possibility that the CDO securities are subordinate to other classes; and (iv) the complex structure of the security may not be fully understood at the time of investment and may produce disputes with the issuer or unexpected investment results.

The credit quality of CDOs depends primarily upon the quality of the underlying assets and the level of credit support and/or enhancement provided. The underlying assets (e.g., securities or loans) of CDOs may be subject to prepayments, which would shorten the weighted average maturity and may lower the return of the CDO. If a credit support or enhancement is exhausted, losses or delays in payment may result if the required payments of principal and interest are not made. The transaction documents relating to the issuance of CDOs may impose eligibility criteria on the assets of the issuing SPV, restrict the ability of the investment manager to trade investments and impose certain portfolio-wide asset quality requirements. These criteria, restrictions and requirements may limit the ability of the SPV's investment manager to maximize returns on the CDOs. In addition, other parties involved in structured products, such as third party credit enhancers and investors in the rated tranches, may impose requirements that have an adverse effect on the returns of the various tranches of CDOs. Furthermore, CDO transaction documents generally contain provisions that, in the event that certain tests are not met (generally interest coverage and over-collateralization tests at varying levels in the capital structure), require that proceeds that would otherwise be distributed to holders of a junior tranche must be diverted to pay down the senior tranches until such tests are satisfied. Failure (or increased likelihood of failure) of a CDO to make timely payments on a particular tranche will have an adverse effect on the liquidity and market value of such tranche.

Payments to holders of CDOs may be subject to deferral. If cash flows generated by the underlying assets are insufficient to make all current and, if applicable, deferred payments on the CDOs, no other assets will be

II-52

available for payment of the deficiency and, following realization of the underlying assets, the obligations of the issuer to pay such deficiency will be extinguished.

The value of CDO securities also may change because of changes in the market's perception of the creditworthiness of the servicing agent for the pool, the originator of the pool, or the financial institution or fund providing the credit support or enhancement. Furthermore, the leveraged nature of each subordinated class may magnify the adverse impact on such class of changes in the value of the assets, changes in the distributions on the assets, defaults and recoveries on the assets, capital gains and losses on the assets, prepayment on the assets and availability, price and interest rates of the assets. CDOs are limited recourse, may not be paid in full and may be subject to up to 100% loss.

CDOs are typically privately offered and sold, and thus are not registered under the securities laws. As a result, investments in CDOs may be characterized by the Fund as illiquid securities; however, an active dealer market may exist which would allow such securities to be considered liquid in some circumstances.

REITs Risk. To the extent that the Fund invests in real estate related investments, including REITs, it will be subject to the risks associated with owning real estate and with the real estate industry generally. These include difficulties in valuing and disposing of real estate, the possibility of declines in the value of real estate, risks related to general and local economic conditions, the possibility of adverse changes in the climate for real estate, environmental liability risks, the risk of increases in property taxes and operating expenses, possible adverse changes in zoning laws, the risk of casualty or condemnation losses, limitations on rents, the possibility of adverse changes in interest rates and in the credit markets and the possibility of borrowers paying off mortgages sooner than expected, which may lead to reinvestment of assets at lower prevailing interest rates. To the extent that the Fund invests in REITs, it will also be subject to the risk that a REIT may default on its obligations or go bankrupt. REITs are generally not taxed on income timely distributed to shareholders, provided they comply with the applicable requirements of the Code. By investing in REITs indirectly through the Fund, a shareholder will bear not only his or her proportionate share of the expenses of the Fund, but also, indirectly, similar expenses of the REITs. Mortgage REITs are pooled investment vehicles that invest the majority of their assets in real property mortgages and which generally derive income primarily from interest payments thereon. Investing in mortgage REITs involves certain risks related to investing in real property mortgages. In addition, mortgage REITs must satisfy highly technical and complex requirements in order to qualify for the favorable tax treatment accorded to REITs under the Code. No assurances can be given that a mortgage REIT in which the Fund invests will be able to continue to qualify as a REIT or that complying with the REIT requirements under the Code will not adversely affect such REIT's ability to execute its business plan.

U.S. Government Securities Risk. U.S. Government debt securities generally involve lower levels of credit risk than other types of fixed income securities of similar maturities, although, as a result, the yields available from U.S. Government debt securities are generally lower than the yields available from such other securities. Like other fixed income securities, the values of U.S. Government securities change as interest rates fluctuate. On August 5, 2011, S&P lowered its long-term sovereign credit rating on U.S. Government debt to AA+ from AAA with a negative outlook. As of September 30, 2014, this rating remains unchanged, but S&P's outlook has been upgraded to "stable." Moody's affirmed the Aaa long-term sovereign credit rating of U.S. Government debt on November 21, 2011 while maintaining its negative outlook, and as of September 30, 2014 this rating remains unchanged, but Moody's outlook has been upgraded to "stable." The downgrade by S&P and any future downgrades by other rating agencies could increase volatility in both stock and bond markets, result in higher interest rates and higher Treasury yields and increase borrowing costs generally. These events could have significant adverse effects on the economy generally and could result in significant adverse impacts on securities issuers and the Fund. The Investment Advisor cannot predict the effects of these or similar events in the future on the U.S. economy and securities markets or on the Fund's portfolio.

Zero Coupon Securities Risk. Zero coupon securities are securities that are sold at a discount to par value and do not pay interest during the life of the security. The discount approximates the total amount of interest the security will accrue and compound over the period until maturity at a rate of interest reflecting the market rate of the security at the time of issuance. Upon maturity, the holder of a zero coupon security is entitled to receive the par value of the security.

II-53

While interest payments are not made on zero coupon securities, holders of such securities are deemed to have received income ("phantom income") annually, notwithstanding that cash may not be received currently. The effect of owning instruments that do not make current interest payments is that a fixed yield is earned not only on the original investment but also, in effect, on all discount accretion during the life of the obligations. This implicit reinvestment of earnings at a fixed rate eliminates the risk of being unable to invest distributions at a rate as high as the implicit yield on the zero coupon bond, but at the same time eliminates the holder's ability to reinvest at higher rates in the future. For this reason, some of these securities may be subject to substantially greater price fluctuations during periods of changing market interest rates than are comparable securities that pay interest currently. Longer term zero coupon bonds are more exposed to interest rate risk than shorter term zero coupon bonds. These investments benefit the issuer by mitigating its need for cash to meet debt service, but also require a higher rate of return to attract investors who are willing to defer receipt of cash.

The Fund accrues income with respect to these securities for Federal income tax and accounting purposes prior to the receipt of cash payments. Zero coupon securities may be subject to greater fluctuation in value and less liquidity in the event of adverse market conditions than comparably rated securities that pay cash interest at regular intervals.

Further, to maintain its qualification for pass-through treatment under the Federal tax laws, the Fund is required to distribute income to its shareholders and, consequently, may have to dispose of other, more liquid portfolio securities under disadvantageous circumstances or may have to leverage itself by borrowing in order to generate the cash to satisfy these distributions. The required distributions may result in an increase in the Fund's exposure to zero coupon securities.

In addition to the above-described risks, there are certain other risks related to investing in zero coupon securities. During a period of severe market conditions, the market for such securities may become even less liquid. In addition, as these securities do not pay cash interest, a Fund's investment exposure to these securities and their risks, including credit risk, will increase during the time these securities are held in the Fund's portfolio.

PIK Bonds Risks. The Fund may invest in PIK bonds. PIK bonds are bonds that pay interest through the issuance of additional debt or equity securities. Similar to zero coupon obligations, PIK bonds also carry additional risk as holders of these types of securities realize no cash until the cash payment date unless a portion of such securities is sold and, if the issuer defaults, the Fund may obtain no return at all on its investment. The market price of PIK bonds is affected by interest rate changes to a greater extent, and therefore tends to be more volatile, than that of securities that pay interest in cash. Additionally, current federal tax law requires the holder of certain PIK bonds to accrue income with respect to these securities prior to the receipt of cash payments. To maintain its qualification as a RIC and avoid liability for federal income and excise taxes, the Fund may be required to distribute income accrued with respect to these securities and may have to dispose of portfolio securities under disadvantageous circumstances in order to generate cash to satisfy these distribution requirements.

Insolvency Considerations with Respect to Issuers of Indebtedness. Various laws enacted for the protection of creditors may apply to indebtedness in which the Fund invests. The information in this and the following paragraph is applicable with respect to U.S. issuers subject to U.S. federal bankruptcy law. Insolvency considerations may differ with respect to other issuers. If, in a lawsuit brought by an unpaid creditor or representative of creditors of an issuer of indebtedness, a court were to find that the issuer did not receive fair consideration or reasonably equivalent value for incurring the indebtedness and that, after giving effect to such indebtedness, the issuer (i) was insolvent, (ii) was engaged in a business for which the remaining assets of such issuer constituted unreasonably small capital or (iii) intended to incur, or believed that it would incur, debts beyond its ability to pay such debts as they mature, such court could determine to invalidate, in whole or in part, such indebtedness as a fraudulent conveyance, to subordinate such indebtedness to existing or future creditors of such issuer, or to recover amounts previously paid by such issuer in satisfaction of such indebtedness. The measure of insolvency for purposes of the foregoing will vary. Generally, an issuer would be considered insolvent at a particular time if the sum of its debts was then greater than all of its property at a fair valuation, or if the present fair saleable value of its assets was then less than the amount that would be required to pay its probable liabilities on its existing debts as they became absolute and matured. There can be no assurance as to what standard a court would apply in order to determine whether the issuer was "insolvent" after giving effect to the incurrence of the indebtedness in which the Fund invested or that, regardless of the method of valuation, a court would not determine that the issuer was "insolvent" upon giving effect to such incurrence. In addition, in the event of the insolvency of

II-54

an issuer of indebtedness in which the Fund invests, payments made on such indebtedness could be subject to avoidance as a "preference" if made within a certain period of time (which may be as long as one year) before insolvency.

The Fund does not anticipate that it will engage in conduct that would form the basis for a successful cause of action based upon fraudulent conveyance, preference or equitable subordination. There can be no assurance, however, as to whether any lending institution or other party from which the Fund may acquire such indebtedness engaged in any such conduct (or any other conduct that would subject such indebtedness and the Fund to insolvency laws) and, if it did, as to whether such creditor claims could be asserted in a U.S. court (or in the courts of any other country) against the Fund.

Indebtedness consisting of obligations of non-U.S. issuers may be subject to various laws enacted in the countries of their issuance for the protection of creditors. These insolvency considerations will differ depending on the country in which each issuer is located or domiciled and may differ depending on whether the issuer is a non-sovereign or a sovereign entity.

Equity Securities Risk. Stock markets are volatile, and the price of equity securities fluctuates based on changes in a company's financial condition and overall market and economic conditions. Although common stocks have historically generated higher average total returns than fixed income securities over the long-term, common stocks also have experienced significantly more volatility in those returns and, in certain periods, have significantly under-performed relative to fixed income securities. An adverse event, such as an unfavorable earnings report, may depress the value of a particular common stock held by the Fund. A common stock may also decline due to factors that affect a particular industry or industries, such as labor shortages or increased production costs and competitive conditions within an industry. The value of a particular common stock held by the Fund may decline for a number of other reasons which directly relate to the issuer, such as management performance, financial leverage, the issuer's historical and prospective earnings, the value of its assets and reduced demand for its goods and services. Also, the price of common stocks is sensitive to general movements in the stock market and a drop in the stock market may depress the price of common stocks to which the Fund has exposure. Common stock prices fluctuate for several reasons, including changes in investors' perceptions of the financial condition of an issuer or the general condition of the relevant stock market, or when political or economic events affecting the issuers occur. In addition, common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common equity securities in which the Fund may invest are structurally subordinated to preferred stock, bonds and other debt instruments in a company's capital structure in terms of priority to corporate income and are therefore inherently more risky than preferred stock or debt instruments of such issuers.

Warrants Risks. If the price of the underlying stock does not rise above the exercise price before the warrant expires, the warrant generally expires without any value and the Fund loses any amount it paid for the warrant. Thus, investments in warrants may involve substantially more risk than investments in common stock. Warrants may trade in the same markets as their underlying stock; however, the price of the warrant does not necessarily move with the price of the underlying stock.

Rights Risks. The failure to exercise subscription rights to purchase common stock would result in the dilution of the Fund's interest in the issuing company. The market for such rights is not well developed, and, accordingly, the Fund may not always realize full value on the sale of rights.

Preferred Securities Risk. There are special risks associated with investing in preferred securities, including:

Deferral. Preferred securities may include provisions that permit the issuer, at its discretion, to defer distributions for a stated period without any adverse consequences to the issuer. If the Fund owns a preferred security that is deferring its distributions, the Fund may be required to report income for tax purposes although it has not yet received such income.

Subordination. Preferred securities are subordinated to bonds and other debt instruments in a company's capital structure in terms of having priority to corporate income and liquidation payments, and therefore will be subject to greater credit risk than debt instruments.

II-55

Limited Voting Rights. Generally, preferred security holders (such as the Fund) have no voting rights with respect to the issuing company unless preferred dividends have been in arrears for a specified number of periods, at which time the preferred security holders may elect a number of directors to the issuer's board. Generally, once all the arrearages have been paid, the preferred security holders no longer have voting rights. In the case of trust preferred securities, holders generally have no voting rights, except if (i) the issuer fails to pay dividends for a specified period of time or (ii) a declaration of default occurs and is continuing.

Special Redemption Rights. In certain varying circumstances, an issuer of preferred securities may redeem the securities prior to a specified date. For instance, for certain types of preferred securities, a redemption may be triggered by certain changes in U.S. federal income tax or securities laws. As with call provisions, a special redemption by the issuer may negatively impact the return of the security held by the Fund.

Trust Preferred Securities. The Fund may invest in trust preferred securities. Trust preferred securities are typically issued by corporations, generally in the form of interest bearing notes with preferred securities characteristics, or by an affiliated business trust of a corporation, generally in the form of beneficial interests in subordinated debentures or similarly structured securities. The trust preferred securities market consists of both fixed and adjustable coupon rate securities that are either perpetual in nature or have stated maturity dates.

Trust preferred securities are typically junior and fully subordinated liabilities of an issuer and benefit from a guarantee that is junior and fully subordinated to the other liabilities of the guarantor. In addition, trust preferred securities typically permit an issuer to defer the payment of income for five years or more without triggering an event of default. Because of their subordinated position in the capital structure of an issuer, the ability to defer payments for extended periods of time without default consequences to the issuer, and certain other features (such as restrictions on common dividend payments by the issuer or ultimate guarantor when full cumulative payments on the trust preferred securities have not been made), these trust preferred securities are often treated as close substitutes for traditional preferred securities, both by issuers and investors.

Trust preferred securities include but are not limited to trust originated preferred securities ("TOPRS®"); monthly income preferred securities ("MIPS®"); quarterly income bond securities ("QUIBS®" ); quarterly income debt securities ("QUIDS®"); quarterly income preferred securities ("QUIPSSM"); corporate trust securities ("CORTS®"); public income notes ("PINES®"); and other trust preferred securities.

Trust preferred securities are typically issued with a final maturity date, although some are perpetual in nature. In certain instances, a final maturity date may be extended and/or the final payment of principal may be deferred at the issuer's option for a specified time without default. No redemption can typically take place unless all cumulative payment obligations have been met, although issuers may be able to engage in open-market repurchases without regard to whether all payments have been paid.

Many trust preferred securities are issued by trusts or other special purpose entities established by operating companies and are not a direct obligation of an operating company. At the time the trust or special purpose entity sells such preferred securities to investors, it purchases debt of the operating company (with terms comparable to those of the trust or special purpose entity securities), which enables the operating company to deduct for tax purposes the interest paid on the debt held by the trust or special purpose entity. The trust or special purpose entity is generally required to be treated as transparent for Federal income tax purposes such that the holders of the trust preferred securities are treated as owning beneficial interests in the underlying debt of the operating company. Accordingly, payments on the trust preferred securities are treated as interest rather than dividends for Federal income tax purposes. The trust or special purpose entity in turn would be a holder of the operating company's debt and would have priority with respect to the operating company's earnings and profits over the operating company's common shareholders, but would typically be subordinated to other classes of the operating company's debt. Typically a preferred share has a rating that is slightly below that of its corresponding operating company's senior debt securities.

New Types of Securities. From time to time, preferred securities, including trust preferred securities, have been, and may in the future be, offered having features other than those described herein. The Fund reserves the right to invest in these securities if the Investment Advisor believes that doing so would be consistent with the Fund's investment objective and policies. Since the market for these instruments would be new, the Fund may have

II-56

difficulty disposing of them at a suitable price and time. In addition to limited liquidity, these instruments may present other risks, such as high price volatility.

Convertible Securities Risk. Convertible securities generally offer lower interest or dividend yields than non-convertible securities of similar quality. As with all fixed income securities, the market values of convertible securities tend to decline as interest rates increase and, conversely, to increase as interest rates decline. However, when the market price of the common stock underlying a convertible security exceeds the conversion price, the convertible security tends to reflect the market price of the underlying common stock. As the market price of the underlying common stock declines, the convertible security tends to trade increasingly on a yield basis and thus may not decline in price to the same extent as the underlying common stock. Convertible securities rank senior to common stock in an issuer's capital structure and consequently entail less risk than the issuer's common stock.

The value of convertible securities is influenced by both the yield on nonconvertible securities of comparable issuers and by the value of the underlying common stock. The value of a convertible security viewed without regard to its conversion feature (i.e., strictly on the basis of its yield) is sometimes referred to as its "investment value." To the extent interest rates change, the investment value of the convertible security typically will fluctuate. At the same time, however, the value of the convertible security will be influenced by its "conversion value," which is the market value of the underlying common stock that would be obtained if the convertible security were converted. Conversion value fluctuates directly with the price of the underlying common stock. If the conversion value of a convertible security is substantially below its investment value, the price of the convertible security is governed principally by its investment value. To the extent the conversion value of a convertible security increases to a point that approximates or exceeds its investment value, the price of the convertible security will be influenced principally by its conversion value. A convertible security will sell at a premium over the conversion value to the extent investors place value on the right to acquire the underlying common stock while holding a fixed income security. The yield and conversion premium of convertible securities issued in Japan and the Euromarket are frequently determined at levels that cause the conversion value to affect their market value more than the securities' investment value.

Holders of convertible securities generally have a claim on the assets of the issuer prior to the common stockholders but may be subordinated to other debt securities of the same issuer. A convertible security may be subject to redemption at the option of the issuer at a price established in a charter provision, indenture or other governing instrument pursuant to which the convertible security was issued. If a convertible security held by the Fund is called for redemption, the Fund will be required to redeem the security, convert it into the underlying common stock or sell it to a third party. Certain convertible debt securities may provide a put option to the holder, which entitles the holder to cause the security to be redeemed by the issuer at a premium over the stated principal amount of the debt security under certain circumstances.

The Fund may also invest in synthetic convertible securities. Synthetic convertible securities may include either Cash-Settled Convertibles or Manufactured Convertibles. Cash-Settled Convertibles are instruments that are created by the issuer and have the economic characteristics of traditional convertible securities but may not actually permit conversion into the underlying equity securities in all circumstances. As an example, a private company may issue a Cash-Settled Convertible that is convertible into common stock only if the company successfully completes a public offering of its common stock prior to maturity and otherwise pays a cash amount to reflect any equity appreciation. Manufactured Convertibles are created by the Investment Advisor or another party by combining separate securities that possess one of the two principal characteristics of a convertible security, i.e., fixed income ("fixed income component") or a right to acquire equity securities ("convertibility component"). The fixed income component is achieved by investing in nonconvertible fixed income securities, such as nonconvertible bonds, preferred stocks and money market instruments. The convertibility component is achieved by investing in call options, warrants, or other securities with equity conversion features ("equity features") granting the holder the right to purchase a specified quantity of the underlying stocks within a specified period of time at a specified price or, in the case of a stock index option, the right to receive a cash payment based on the value of the underlying stock index.

A Manufactured Convertible differs from traditional convertible securities in several respects. Unlike a traditional convertible security, which is a single security that has a unitary market value, a Manufactured Convertible is comprised of two or more separate securities, each with its own market value. Therefore, the total "market value" of such a Manufactured Convertible is the sum of the values of its fixed income component and its convertibility component.

II-57

A holder of a synthetic convertible security faces the risk of a decline in the price of the security or the level of the index involved in the convertible component, causing a decline in the value of the security or instrument, such as a call option or warrant, purchased to create the synthetic convertible security. Should the price of the stock fall below the exercise price and remain there throughout the exercise period, the entire amount paid for the call option or warrant would be lost. Because a synthetic convertible security includes the income-producing component as well, the holder of a synthetic convertible security also faces the risk that interest rates will rise, causing a decline in the value of the income-producing instrument. Synthetic convertible securities are also subject to the risks associated with derivatives.

More flexibility is possible in the creation of a Manufactured Convertible than in the purchase of a traditional convertible security. Because many corporations have not issued convertible securities, the Investment Advisor may combine a fixed income instrument and an equity feature with respect to the stock of the issuer of the fixed income instrument to create a synthetic convertible security otherwise unavailable in the market. The Investment Advisor may also combine a fixed income instrument of an issuer with an equity feature with respect to the stock of a different issuer when the Investment Advisor believes such a Manufactured Convertible would better promote the Fund's investment objective than alternative investments. For example, the Investment Advisor may combine an equity feature with respect to an issuer's stock with a fixed income security of a different issuer in the same industry to diversify the Fund's credit exposure, or with a U.S. Treasury instrument to create a Manufactured Convertible with a higher credit profile than a traditional convertible security issued by that issuer. A Manufactured Convertible also is a more flexible investment in that its two components may be purchased separately and, upon purchasing the separate securities, "combined" to create a Manufactured Convertible. For example, the Fund may purchase a warrant for eventual inclusion in a Manufactured Convertible while postponing the purchase of a suitable bond to pair with the warrant pending development of more favorable market conditions.

The value of a Manufactured Convertible may respond to certain market fluctuations differently from a traditional convertible security with similar characteristics. For example, in the event the Fund created a Manufactured Convertible by combining a short-term U.S. Treasury instrument and a call option on a stock, the Manufactured Convertible would be expected to outperform a traditional convertible of similar maturity that is convertible into that stock during periods when Treasury instruments outperform corporate fixed income securities and underperform during periods when corporate fixed income securities outperform Treasury instruments.

Restricted and Illiquid Securities Risk. The Fund may invest in illiquid or less liquid securities or securities in which no secondary market is readily available or which are otherwise illiquid, including private placement securities. The Fund may not be able to readily dispose of such securities at prices that approximate those at which the Fund could sell such securities if they were more widely-traded and, as a result of such illiquidity, the Fund may have to sell other investments or engage in borrowing transactions if necessary to raise cash to meet its obligations. Limited liquidity can also affect the market price of securities, thereby adversely affecting the Fund's NAV and ability to make dividend distributions. The financial markets in general, and certain segments of the mortgage related securities markets in particular, have in recent years experienced periods of extreme secondary market supply and demand imbalance, resulting in a loss of liquidity during which market prices were suddenly and substantially below traditional measures of intrinsic value. During such periods, some securities could be sold only at arbitrary prices and with substantial losses. Periods of such market dislocation may occur again at any time. Privately issued debt securities are often of below investment grade quality, frequently are unrated and present many of the same risks as investing in below investment grade public debt securities.

Restricted securities are securities that may not be sold to the public without an effective registration statement under the Securities Act, or that may be sold only in a privately negotiated transaction or pursuant to an exemption from registration. When registration is required to sell a security, the Fund may be obligated to pay all or part of the registration expenses and considerable time may pass before the Fund is permitted to sell a security under an effective registration statement. If adverse market conditions develop during this period, the Fund might obtain a less favorable price than the price that prevailed when the Fund decided to sell. The Fund may be unable to sell restricted and other illiquid securities at opportune times or prices.

Municipal Securities Risk. Municipal securities involve certain risks. The municipal market is one in which dealer firms make markets in securities on a principal basis using their proprietary capital, and during the recent market turmoil these firms' capital was severely constrained. As a result, some firms were unwilling to commit their capital to purchase and to serve as a dealer for municipal securities. Municipal securities are generally not registered

II-58

with the SEC or any state securities commission and will not be listed on any national securities exchange. The amount of public information available about the municipal securities to which the Fund is economically exposed is generally less than that for corporate equities or bonds, and the investment performance of the Fund may therefore be more dependent on the analytical abilities of the Investment Advisor. The secondary market for municipal securities, particularly the below investment grade securities to which the Fund may be economically exposed, also tends to be less well-developed or liquid than many other securities markets, which may adversely affect the Fund's ability to sell such securities at prices approximating those at which the Fund may currently value them.

In addition, many state and municipal governments that issue securities are under significant economic and financial stress and may not be able to satisfy their obligations. The ability of municipal issuers to make timely payments of interest and principal may be diminished during general economic downturns and as governmental cost burdens are reallocated among federal, state and local governments. The taxing power of any governmental entity may be limited by provisions of state constitutions or laws and an entity's credit will depend on many factors, including the entity's tax base, the extent to which the entity relies on federal or state aid and other factors which are beyond the entity's control. In addition, laws enacted in the future by Congress or state legislatures or referenda could extend the time for payment of principal and/or interest, or impose other constraints on enforcement of such obligations or on the ability of municipalities to levy taxes. Issuers of municipal securities might seek protection under bankruptcy laws. In the event of bankruptcy of such an issuer, holders of municipal securities could experience delays in collecting principal and interest and such holders may not be able to collect all principal and interest to which they are entitled. To enforce its rights in the event of a default in the payment of interest or repayment of principal, or both, the Fund may take possession of and manage the assets securing the issuer's obligations on such securities, which may increase the Fund's operating expenses. Any income derived from the Fund's ownership or operation of such assets could jeopardize the Fund's status as a RIC under the Code.

Revenue bonds issued by state or local agencies to finance the development of low-income, multi-family housing involve special risks in addition to those associated with municipal securities generally, including that the underlying properties may not generate sufficient income to pay expenses and interest costs. Such securities are generally non-recourse against the property owner, may be junior to the rights of others with an interest in the properties, may pay interest that changes based in part on the financial performance of the property, may be prepayable without penalty and may be used to finance the construction of housing developments which, until completed and rented, do not generate income to pay interest. Increases in interest rates payable on senior obligations may make it more difficult for issuers to meet payment obligations on subordinated bonds.

Municipal leases and certificates of participation involve special risks not normally associated with general obligations or revenue bonds. Leases and installment purchase or conditional sale contracts (which normally provide for title to the leased asset to pass eventually to the governmental issuer) have evolved as a means for governmental issuers to acquire property and equipment without meeting the constitutional and statutory requirements for the issuance of debt. Such debt issuance limitations are usually deemed to be inapplicable because of the inclusion in many leases or contracts of "non-appropriation" clauses that relieve the governmental issuer of any obligation to make future payments under the lease or contract unless money is appropriated for such purpose by the appropriate legislative body on a yearly or other periodic basis. In addition, such leases or contracts may be subject to temporary abatement of payments in the event the governmental issuer is prevented from maintaining occupancy of the leased premises or utilizing the leased equipment. Although the obligations may be secured by the leased equipment or facilities, the disposition of the property in the event of non-appropriation or foreclosure might prove difficult, time consuming and costly, and may result in a delay in recovering or the failure to fully recover ownership of the assets.

Certificates of participation, which represent interests in unmanaged pools of municipal leases or installment contracts, involve the same risks as the underlying municipal leases. In addition, the Fund may be dependent upon the municipal authority issuing the certificate of participation to exercise remedies with respect to the underlying securities. Certificates of participation also entail a risk of default or bankruptcy, both of the issuer of the municipal lease and also the municipal agency issuing the certificate of participation.

Municipal securities, like other debt obligations, are subject to the risk of nonpayment. The ability of issuers of municipal securities to make timely payments of interest and principal may be adversely impacted in general economic downturns and as relative governmental cost burdens are allocated and reallocated among federal, state and local governmental units. Such nonpayment would result in a reduction of income to the Fund and could

II-59

result in a reduction in the value of the municipal security experiencing nonpayment and a potential decrease in the NAV of the Fund. A decline in income could affect the Fund's ability to pay dividends on the common shares.

The risks and special considerations involved in investment in municipal securities vary with the types of instruments being acquired.

The value of municipal securities generally may be affected by uncertainties in the municipal markets as a result of legislation or litigation, including legislation or litigation that changes the taxation of municipal securities or the rights of municipal security holders in the event of a bankruptcy. Certain provisions of the U.S. Bankruptcy Code governing such bankruptcies are unclear. Further, the application of state law to municipal security issuers could produce varying results among the states or among municipal security issuers within a state. These uncertainties could have a significant impact on the prices of the municipal securities in which the Fund invests.

The U.S. economy may be in the process of "deleveraging," with individuals, companies and municipalities reducing expenditures and paying down borrowings. In such event, the number of municipal borrowers and the amount of outstanding municipal securities may contract, potentially without corresponding reductions in investor demand for municipal securities. As a result, the Fund may have fewer investment alternatives, may invest in securities that it previously would have declined and may concentrate its investments in a smaller number of issuers.

Non-U.S. Securities Risk. The Fund may invest in Non-U.S. Securities. Such investments involve certain risks not involved in domestic investments. Securities markets in foreign countries often are not as developed, efficient or liquid as securities markets in the United States, and therefore, the prices of Non-U.S. Securities can be more volatile. Certain foreign countries may impose restrictions on the ability of issuers of Non-U.S. Securities to make payments of principal and interest to investors located outside the country. In addition, the Fund will be subject to risks associated with adverse political and economic developments in foreign countries, which could cause the Fund to lose money on its investments in Non-U.S. Securities. The Fund will be subject to additional risks if it invests in Non-U.S. Securities, which include seizure or nationalization of foreign deposits. Non-U.S. Securities may trade on days when the Fund's common shares are not priced or traded.

Rules adopted under the 1940 Act permit the Fund to maintain its Non-U.S. Securities and foreign currency in the custody of certain eligible non-U.S. banks and securities depositories, and the Fund generally holds its Non-U.S. Securities and foreign currency in foreign banks and securities depositories. Some foreign banks and securities depositories may be recently organized or new to the foreign custody business. In addition, there may be limited or no regulatory oversight of their operations. Also, the laws of certain countries limit the Fund's ability to recover its assets if a foreign bank, depository or issuer of a security, or any of their agents, goes bankrupt. In addition, it is often more expensive for the Fund to buy, sell and hold securities in certain foreign markets than in the United States. The increased expense of investing in foreign markets reduces the amount the Fund can earn on its investments and typically results in a higher operating expense ratio for the Fund than for investment companies invested only in the United States.

Certain banks in foreign countries may not be eligible sub-custodians for the Fund, in which event the Fund may be precluded from purchasing securities in certain foreign countries in which it otherwise would invest or the Fund may incur additional costs and delays in providing transportation and custody services for such securities outside of such countries. The Fund may encounter difficulties in effecting portfolio transactions on a timely basis with respect to any securities of issuers held outside their countries.

The economies of certain foreign markets may not compare favorably with the economy of the United States with respect to such issues as growth of gross national product, reinvestment of capital, resources and balance of payments position. Certain foreign economies may rely heavily on particular industries or foreign capital and are more vulnerable to diplomatic developments, the imposition of economic sanctions against a particular country or countries, changes in international trading patterns, trade barriers and other protectionist or retaliatory measures. Investments in foreign markets may also be adversely affected by governmental actions such as the imposition of capital controls, nationalization of companies or industries, expropriation of assets or the imposition of punitive taxes. In addition, the governments of certain countries may prohibit or impose substantial restrictions on foreign investments in their capital markets or in certain industries. Any of these actions could severely affect securities prices or impair the Fund's ability to purchase or sell Non-U.S. Securities or transfer the Fund's assets or income back into the United States, or otherwise adversely affect the Fund's operations. In addition, the U.S. Government

II-60

has from time to time in the past imposed restrictions, through penalties and otherwise, on foreign investments by U.S. investors such as the Fund. If such restrictions should be reinstituted, it might become necessary for the Fund to invest all or substantially all of its assets in U.S. securities.

Other potential foreign market risks include foreign exchange controls, difficulties in pricing securities, defaults on foreign government securities, difficulties in enforcing legal judgments in foreign courts and political and social instability. Diplomatic and political developments, including rapid and adverse political changes, social instability, regional conflicts, terrorism and war, could affect the economies, industries and securities and currency markets, and the value of the Fund's investments, in non-U.S. countries. These factors are extremely difficult, if not impossible, to predict and take into account with respect to the Fund's investments.

In general, less information is publicly available with respect to foreign issuers than is available with respect to U.S. companies. Accounting standards in other countries are not necessarily the same as in the United States. If the accounting standards in another country do not require as much detail as U.S. accounting standards, it may be harder for the Investment Advisor to completely and accurately determine a company's financial condition.

Many foreign governments do not supervise and regulate stock exchanges, brokers and the sale of securities to the same extent as such regulations exist in the United States. They also may not have laws to protect investors that are comparable to U.S. securities laws. For example, some foreign countries may have no laws or rules against insider trading. Insider trading occurs when a person buys or sells a company's securities based on material non-public information about that company. In addition, some countries may have legal systems that may make it difficult for the Fund to vote proxies, exercise shareholder rights, and pursue legal remedies with respect to its Non-U.S. Securities.

Settlement and clearance procedures in certain foreign markets differ significantly from those in the United States. Foreign settlement and clearance procedures and trade regulations also may involve certain risks (such as delays in payment for or delivery of securities) not typically associated with the settlement of U.S. investments. Communications between the United States and foreign countries may be unreliable, increasing the risk of delayed settlements or losses of security certificates in markets that still rely on physical settlement. At times, settlements in certain foreign countries have not kept pace with the number of securities transactions. These problems may make it difficult for the Fund to carry out transactions. If the Fund cannot settle or is delayed in settling a purchase of securities, it may miss attractive investment opportunities and certain of its assets may be uninvested with no return earned thereon for some period. If the Fund cannot settle or is delayed in settling a sale of securities, it may lose money if the value of the security then declines or, if it has contracted to sell the security to another party, the Fund could be liable for any losses incurred.

While the volume of transactions effected on foreign stock exchanges has increased in recent years, it remains appreciably below that of the NYSE. Accordingly, the Fund's Non-U.S. Securities may be less liquid and their prices may be more volatile than comparable investments in securities in U.S. companies.

A number of countries have authorized the formation of closed-end investment companies to facilitate indirect foreign investment in their capital markets. In accordance with the 1940 Act, the Fund may invest up to 10% of its total assets in securities of closed-end investment companies, not more than 5% of which may be invested in any one such company. This restriction on investments in securities of closed-end investment companies may limit opportunities for the Fund to invest indirectly in certain smaller capital markets. Shares of certain closed-end investment companies may at times be acquired only at market prices representing premiums to their NAVs. If the Fund acquires shares in closed-end investment companies, shareholders would bear both their proportionate share of the Fund's expenses (including investment advisory fees) and, indirectly, the expenses of such closed-end investment companies. The Fund also may seek, at its own cost, to create its own investment entities under the laws of certain countries.

Emerging Markets Risk. The Fund may invest in Non-U.S. Securities of issuers in so-called "emerging markets" (or lesser developed countries). Such investments are particularly speculative and entail all of the risks of investing in Non-U.S. Securities but to a heightened degree. "Emerging market" countries generally include every nation in the world except developed countries, that is, the United States, Canada, Japan, Australia, New Zealand and most countries located in Western Europe. Investments in the securities of issuers domiciled in countries with emerging capital markets involve certain additional risks that do not generally apply to investments in securities of

II-61

issuers in more developed capital markets, such as (i) low or non-existent trading volume, resulting in a lack of liquidity and increased volatility in prices for such securities, as compared to securities of comparable issuers in more developed capital markets; (ii) uncertain national policies and social, political and economic instability, increasing the potential for expropriation of assets, confiscatory taxation, high rates of inflation or unfavorable diplomatic developments; (iii) possible fluctuations in exchange rates, differing legal systems and the existence or possible imposition of exchange controls, custodial restrictions or other foreign or U.S. governmental laws or restrictions applicable to such investments; (iv) national policies that may limit the Fund's investment opportunities such as restrictions on investment in issuers or industries deemed sensitive to national interests; and (v) the lack or relatively early development of legal structures governing private and foreign investments and private property.

Foreign investment in certain emerging market countries may be restricted or controlled to varying degrees. These restrictions or controls may at times limit or preclude foreign investment in certain emerging market issuers and increase the costs and expenses of the Fund. Certain emerging market countries require governmental approval prior to investments by foreign persons in a particular issuer, limit the amount of investment by foreign persons in a particular issuer, limit the investment by foreign persons only to a specific class of securities of an issuer that may have less advantageous rights than the classes available for purchase by domiciliaries of the countries and/or impose additional taxes on foreign investors.

Emerging markets are more likely to experience hyperinflation and currency devaluations, which adversely affect returns to U.S. investors. In addition, many emerging markets have far lower trading volumes and less liquidity than developed markets. Since these markets are often small, they may be more likely to suffer sharp and frequent price changes or long-term price depression because of adverse publicity, investor perceptions or the actions of a few large investors. In addition, traditional measures of investment value used in the United States, such as price to earnings ratios, may not apply to certain small markets. Also, there may be less publicly available information about issuers in emerging markets than would be available about issuers in more developed capital markets, and such issuers may not be subject to accounting, auditing and financial reporting standards and requirements comparable to those to which U.S. companies are subject. In certain countries with emerging capital markets, reporting standards vary widely.

Many emerging markets have histories of political instability and abrupt changes in policies and these countries may lack the social, political and economic stability characteristic of more developed countries. As a result, their governments are more likely to take actions that are hostile or detrimental to private enterprise or foreign investment than those of more developed countries, including expropriation of assets, confiscatory taxation, high rates of inflation or unfavorable diplomatic developments. In the past, governments of such nations have expropriated substantial amounts of private property, and most claims of the property owners have never been fully settled. There is no assurance that such expropriations will not reoccur. In such an event, it is possible that the Fund could lose the entire value of its investments in the affected market. Some countries have pervasiveness of corruption and crime that may hinder investments. Certain emerging markets may also face other significant internal or external risks, including the risk of war, and ethnic, religious and racial conflicts. In addition, governments in many emerging market countries participate to a significant degree in their economies and securities markets, which may impair investment and economic growth. National policies that may limit the Fund's investment opportunities include restrictions on investment in issuers or industries deemed sensitive to national interests. In such a dynamic environment, there can be no assurance that any or all of these capital markets will continue to present viable investment opportunities for the Fund.

Emerging markets may also have differing legal systems and the existence or possible imposition of exchange controls, custodial restrictions or other foreign or U.S. governmental laws or restrictions applicable to such investments. Sometimes, they may lack or be in the relatively early development of legal structures governing private and foreign investments and private property. In addition to withholding taxes on investment income, some countries with emerging markets may impose differential capital gains taxes on foreign investors.

Practices in relation to settlement of securities transactions in emerging markets involve higher risks than those in developed markets, in part because the Fund will need to use brokers and counterparties that are less well capitalized, and custody and registration of assets in some countries may be unreliable. The possibility of fraud, negligence, undue influence being exerted by the issuer or refusal to recognize ownership exists in some emerging markets, and, along with other factors, could result in ownership registration being completely lost. The Fund would absorb any loss resulting from such registration problems and may have no successful claim for compensation. In

II-62

addition, communications between the United States and emerging market countries may be unreliable, increasing the risk of delayed settlements or losses of security certificates.

Foreign Currency Risk. Because the Fund may invest in securities denominated or quoted in currencies other than the U.S. dollar, changes in foreign currency exchange rates may affect the value of securities in the Fund and the unrealized appreciation or depreciation of investments. Currencies of certain countries may be volatile and therefore may affect the value of securities denominated in such currencies, which means that the Fund's NAV could decline as a result of changes in the exchange rates between foreign currencies and the U.S. dollar. The Investment Advisor may, but is not required to, elect for the Fund to seek to protect itself from changes in currency exchange rates through hedging transactions depending on market conditions. In addition, certain countries, particularly emerging market countries, may impose foreign currency exchange controls or other restrictions on the transferability, repatriation or convertibility of currency.

Sovereign Government and Supranational Debt Risk. Investments in sovereign debt involve special risks. Foreign governmental issuers of debt or the governmental authorities that control the repayment of the debt may be unable or unwilling to repay principal or pay interest when due. In the event of default, there may be limited or no legal recourse in that, generally, remedies for defaults must be pursued in the courts of the defaulting party. Political conditions, especially a sovereign entity's willingness to meet the terms of its debt obligations, are of considerable significance. The ability of a foreign sovereign issuer, especially an emerging market country, to make timely payments on its debt obligations will also be strongly influenced by the sovereign issuer's balance of payments, including export performance, its access to international credit facilities and investments, fluctuations of interest rates and the extent of its foreign reserves. The cost of servicing external debt will also generally be adversely affected by rising international interest rates, as many external debt obligations bear interest at rates which are adjusted based upon international interest rates. Also, there can be no assurance that the holders of commercial bank loans to the same sovereign entity may not contest payments to the holders of sovereign debt in the event of default under commercial bank loan agreements. In addition, there is no bankruptcy proceeding with respect to sovereign debt on which a sovereign has defaulted and the Fund may be unable to collect all or any part of its investment in a particular issue. Foreign investment in certain sovereign debt is restricted or controlled to varying degrees, including requiring governmental approval for the repatriation of income, capital or proceeds of sales by foreign investors. These restrictions or controls may at times limit or preclude foreign investment in certain sovereign debt and increase the costs and expenses of the Fund.

LIBOR Risk. According to various reports, certain financial institutions, commencing as early as 2005 and throughout the global financial crisis, routinely made artificially low submissions in the LIBOR rate setting process. Since the LIBOR scandal came to light, several financial institutions have been fined significant amounts by various financial regulators in connection with allegations of manipulation of LIBOR rates. Other financial institutions in various countries are being investigated for similar actions. These developments may have adversely affected the interest rates on securities whose interest payments were determined by reference to LIBOR. Any future similar developments could, in turn, reduce the value of such securities owned by the Fund.

Leverage Risk. The use of leverage creates an opportunity for increased common share net investment income dividends, but also creates risks for the holders of common shares. The Fund cannot assure you that the use of leverage will result in a higher yield on the common shares. The Fund's leveraging strategy may not be successful.

Leverage involves risks and special considerations for common shareholders, including:

the likelihood of greater volatility of NAV, market price and dividend rate of the common shares than a comparable portfolio without leverage;

the risk that fluctuations in interest rates on borrowings and short-term debt or in the interest or dividend rates on any leverage that the Fund must pay will reduce the return to the common shareholders;

II-63

the effect of leverage in a declining market, which is likely to cause a greater decline in the NAV of the common shares than if the Fund were not leveraged, which may result in a greater decline in the market price of the common shares;

when the Fund uses financial leverage, the management fee payable to the Investment Advisor will be higher than if the Fund did not use leverage; and

leverage may increase operating costs, which may reduce total return.

Any decline in the NAV of the Fund's investments will be borne entirely by the holders of common shares. Therefore, if the market value of the Fund's portfolio declines, leverage will result in a greater decrease in NAV to the holders of common shares than if the Fund were not leveraged. This greater NAV decrease will also tend to cause a greater decline in the market price for the common shares. While the Fund may from time to time consider reducing leverage in response to actual or anticipated changes in interest rates in an effort to mitigate the increased volatility of current income and NAV associated with leverage, there can be no assurance that the Fund will actually reduce leverage in the future or that any reduction, if undertaken, will benefit the holders of common shares. Changes in the future direction of interest rates are very difficult to predict accurately. If the Fund were to reduce leverage based on a prediction about future changes to interest rates, and that prediction turned out to be incorrect, the reduction in leverage would likely operate to reduce the income and/or total returns to holders of common shares relative to the circumstance where the Fund had not reduced leverage. The Fund may decide that this risk outweighs the likelihood of achieving the desired reduction to volatility in income and share price if the prediction were to turn out to be correct, and determine not to reduce leverage as described above.

Certain types of leverage used by the Fund may result in the Fund being subject to covenants relating to asset coverage and portfolio composition requirements. The Fund may be subject to certain restrictions on investments imposed by guidelines of one or more rating agencies, which may issue ratings for any debt securities or preferred shares issued by the Fund. The terms of any borrowings or these rating agency guidelines may impose asset coverage or portfolio composition requirements that are more stringent than those imposed by the 1940 Act. The Investment Advisor does not believe that these covenants or guidelines will impede it from managing the Fund's portfolio in accordance with the Fund's investment objective and policies.

The Fund may invest in the securities of other investment companies. Such investment companies may also be leveraged, and will therefore be subject to the leverage risks described above. This additional leverage may in certain market conditions reduce the NAV of the Fund's common shares and the returns to the holders of common shares.

Event Risk. Event risk is the risk that corporate issuers may undergo restructurings, such as mergers, leveraged buyouts, takeovers, or similar events financed by increased debt. As a result of the added debt, the credit quality and market value of a company's securities may decline significantly.

Inverse Floater and Related Securities Risk. Investments in inverse floaters, residual interest tender option bonds and similar instruments expose the Fund to the same risks as investments in fixed income securities and derivatives, as well as other risks, including those associated with leverage and increased volatility. An investment in these securities typically will involve greater risk than an investment in a fixed rate security. Distributions on inverse floaters, residual interest tender option bonds and similar instruments will typically bear an inverse relationship to short term interest rates and typically will be reduced or, potentially, eliminated as interest rates rise. Inverse floaters, residual interest tender option bonds and similar instruments will underperform the market for fixed rate securities in a rising interest rate environment. Inverse floaters may be considered to be leveraged to the extent that their interest rates vary by a magnitude that exceeds the magnitude of the change in a reference rate of interest (typically a short term interest rate). The leverage inherent in inverse floaters is associated with greater volatility in their market values. Investments in inverse floaters, residual interest tender option bonds and similar instruments that have fixed income securities underlying them will expose the Fund to the risks associated with those fixed income securities and the values of those investments may be especially sensitive to changes in prepayment rates on the underlying fixed income securities.

Inflation-Indexed Bonds Risk. Inflation-indexed securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the value of an inflation-indexed

II-64

security, including TIPs, tends to decrease when real interest rates increase and can increase when real interest rates decrease. Thus generally, during periods of rising inflation, the value of inflation-indexed securities will tend to increase and during periods of deflation, their value will tend to decrease. Interest payments on inflation-indexed securities are unpredictable and will fluctuate as the principal and interest are adjusted for inflation. There can be no assurance that the inflation index used (e.g., the Consumer Price Index for All Urban Consumers) will accurately measure the real rate of inflation in the prices of goods and services. Any increase in the principal amount of an inflation-indexed debt security will be considered taxable ordinary income, even though the Fund will not receive the principal until maturity. In order to receive the special treatment accorded to RICs and their shareholders under the Code and to avoid U.S. federal income and/or excise taxes at the Fund level, the Fund may be required to distribute this income to shareholders in the tax year in which the income is recognized (without a corresponding receipt of cash). Therefore, the Fund may be required to pay out as an income distribution in any such tax year an amount greater than the total amount of cash income the Fund actually received and to sell portfolio securities, including at potentially disadvantageous times or prices, to obtain cash needed for these income distributions.

Two structures are common. The U.S. Treasury and some other issuers use a structure that accrues inflation into the principal value of the bond. Most other issuers pay out the Consumer Price Index ("CPI") accruals as part of a semi-annual coupon.

Inflation-indexed securities issued by the U.S. Treasury have maturities of five, ten or thirty years, although it is possible that securities with other maturities will be issued in the future. The U.S. Treasury securities pay interest on a semi-annual basis, equal to a fixed percentage of the inflation-adjusted principal amount. For example, if the Fund purchased an inflation-indexed bond with a par value of $1,000 and a 3% real rate of return coupon (payable 1.5% semi-annually), and inflation over the first six months was 1%, the mid-year par value of the bond would be $1,010 and the first semi-annual interest payment would be $15.15 ($1,010 times 1.5%). If inflation during the second half of the year resulted in the whole year's inflation equaling 3%, the end-of-year par value of the bond would be $1,030 and the second semi-annual interest payment would be $15.45 ($1,030 times 1.5%).

If the periodic adjustment rate measuring inflation falls, the principal value of inflation-indexed bonds will be adjusted downward, and, consequently, the interest payable on these securities (calculated with respect to a smaller principal amount) will be reduced. Repayment of the original bond principal upon maturity (as adjusted for inflation) is guaranteed in the case of U.S. Treasury inflation-indexed bonds, even during a period of deflation. However, the current market value of the bonds is not guaranteed, and will fluctuate. The Fund may also invest in other inflation related bonds that may or may not provide a similar guarantee. If a guarantee of principal is not provided, the adjusted principal value of the bond repaid at maturity may be less than the original principal. In addition, if the Fund purchases inflation-indexed bonds offered by foreign issuers, the rate of inflation measured by the foreign inflation index may not be correlated to the rate of inflation in the United States.

The value of inflation-indexed bonds is expected to change in response to changes in real interest rates. Real interest rates, in turn, are tied to the relationship between nominal interest rates and the rate of inflation. Therefore, if inflation were to rise at a faster rate than nominal interest rates, real interest rates might decline, leading to an increase in value of inflation-indexed bonds. In contrast, if nominal interest rates increased at a faster rate than inflation, real interest rates might rise, leading to a decrease in value of inflation-indexed bonds. There can be no assurance, however, that the value of inflation-indexed bonds will be directly correlated to changes in interest rates.

While these securities are expected to be protected from long-term inflationary trends, short-term increases in inflation may lead to a decline in value. If interest rates rise due to reasons other than inflation (for example, due to changes in currency exchange rates), investors in these securities may not be protected to the extent that the increase is not reflected in the bond's inflation measure.

In general, the measure used to determine the periodic adjustment of U.S. inflation-indexed bonds is the Consumer Price Index for Urban Consumers ("CPI-U"), which is calculated monthly by the U.S. Bureau of Labor Statistics. The CPI-U is a measurement of changes in the cost of living, made up of components such as housing, food, transportation and energy. Inflation-indexed bonds issued by a foreign government are generally adjusted to reflect a comparable inflation index, calculated by that government. There can be no assurance that the CPI-U or any foreign inflation index will accurately measure the real rate of inflation in the prices of goods and services.

II-65

Moreover, there can be no assurance that the rate of inflation in a foreign country will be correlated to the rate of inflation in the United States.

Any increase in the principal amount of an inflation-indexed bond will be considered taxable ordinary income, even though investors do not receive their principal until maturity.

Defensive Investing Risk. For defensive purposes, the Fund may allocate assets into cash or short-term fixed income securities without limitation. In doing so, the Fund may succeed in avoiding losses but may otherwise fail to achieve its investment objective. Further, the value of short-term fixed income securities may be affected by changing interest rates and by changes in credit ratings of the investments. If the Fund holds cash uninvested it will be subject to the credit risk of the depository institution holding the cash.

Structured Investments Risks. The Fund may invest in structured products, including structured notes, credit linked securities and other types of structured products. Holders of structured products bear risks of the underlying investments, index or reference obligation and are subject to counterparty risk. The Fund may have the right to receive payments only from the structured product and generally does not have direct rights against the issuer or the entity that sold the assets to be securitized. While certain structured products enable the investor to acquire interests in a pool of securities without the brokerage and other expenses associated with directly holding the same securities, investors in structured products generally pay their share of the structured product's administrative and other expenses. Although it is difficult to predict whether the prices of indices and securities underlying structured products will rise or fall, these prices (and, therefore, the prices of structured products) will be influenced by the same types of political and economic events that affect issuers of securities and capital markets generally. If the issuer of a structured product uses shorter term financing to purchase longer term securities, the issuer may be forced to sell its securities at below market prices if it experiences difficulty in obtaining such financing, which may adversely affect the value of the structured products owned by the Fund.

Structured Notes Risk. Investments in structured notes involve risks, including credit risk and market risk. Where the Fund's investments in structured notes are based upon the movement of one or more factors, including currency exchange rates, interest rates, referenced bonds and stock indices, depending on the factor used and the use of multipliers or deflators, changes in interest rates and movement of the factor may cause significant price fluctuations. Additionally, changes in the reference instrument or security may cause the interest rate on the structured note to be reduced to zero and any further changes in the reference instrument may then reduce the principal amount payable on maturity. Structured notes may be less liquid than other types of securities and more volatile than the reference instrument or security underlying the note.

Event-Linked Securities Risk. Event-linked securities are a form of derivative issued by insurance companies and insurance-related special purpose vehicles that apply securitization techniques to catastrophic property and casualty damages. Unlike other insurable low-severity, high-probability events, the insurance risk of which can be diversified by writing large numbers of similar policies, the holders of a typical event-linked securities are exposed to the risks from high-severity, low-probability events such as that posed by major earthquakes or hurricanes. If a catastrophe occurs that "triggers" the event-linked security, investors in such security may lose some or all of the capital invested. In the case of an event, the funds are paid to the bond sponsor—an insurer, reinsurer or corporation—to cover losses. In return, the bond sponsors pay interest to investors for this catastrophe protection. Event-linked securities can be structured to pay-off on three types of variables—insurance-industry catastrophe loss indices, insure-specific catastrophe losses and parametric indices based on the physical characteristics of catastrophic events. Such variables are difficult to predict or model, and the risk and potential return profiles of event-linked securities may be difficult to assess. Catastrophe-related event-linked securities have been in use since the 1990s, and the securitization and risk-transfer aspects of such event-linked securities are beginning to be employed in other insurance and risk-related areas. No active trading market may exist for certain event-linked securities, which may impair the ability of the Fund to realize full value in the event of the need to liquidate such assets.

Equity-Linked Notes Risk. Equity-linked notes are hybrid securities with characteristics of both fixed income and equity securities. An equity-linked note is a debt instrument, usually a bond, that pays interest based upon the performance of an underlying equity, which can be a single stock, basket of stocks or an equity index. The interest payment on an equity-linked note may in some cases be leveraged so that, in percentage terms, it exceeds

II-66

the relative performance of the market. Equity-linked notes generally are subject to the risks associated with the securities of equity issuers, default risk and counterparty risk.

Credit-Linked Securities Risk. A credit-linked security is a derivative instrument. It is a synthetic obligation between two or more parties where the payment of principal and/or interest is based on the performance of some obligation (a reference obligation). In addition to the credit risk of the reference obligations and interest rate risk, the buyer/seller of the credit-linked security is subject to counterparty risk.

Investment Companies Risk. Subject to the limitations set forth in the 1940 Act and the Fund's investment policies and governing documents or as otherwise permitted by the SEC, the Fund may acquire shares in other investment companies and in ETFs or BDCs. The market value of the shares of other investment companies, ETFs and BDCs may differ from their NAV. As an investor in investment companies, ETFs and BDCs, the Fund would bear its ratable share of that entity's expenses, including its investment advisory and administration fees, while continuing to pay its own advisory and administration fees and other expenses. As a result, shareholders will be absorbing duplicate levels of fees with respect to investments in other investment companies, ETFs and BDCs.

The securities of other investment companies, ETFs and BDCs in which the Fund may invest may be leveraged. As a result, the Fund may be indirectly exposed to leverage through an investment in such securities. An investment in securities of other investment companies, ETFs and BDCs that use leverage may expose the Fund to higher volatility in the market value of such securities and the possibility that the Fund's long-term returns on such securities (and, indirectly, the long-term returns of the Fund's common shares) will be diminished.

ETFs are generally not actively managed and may be affected by a general decline in market segments relating to its index. An ETF typically invests in securities included in, or representative of, its index regardless of their investment merits and does not attempt to take defensive positions in declining markets.

Repurchase Agreements Risk. Subject to its investment objective and policies, the Fund may invest in repurchase agreements for leverage or investment purposes. Repurchase agreements typically involve the acquisition by the Fund of fixed income securities from a selling financial institution such as a bank, savings and loan association or broker-dealer. The agreement provides that the Fund will sell the securities back to the institution at a fixed time in the future. The Fund does not bear the risk of a decline in the value of the underlying security unless the seller defaults under its repurchase obligation. In the event of the bankruptcy or other default of a seller of a repurchase agreement, the Fund could experience both delays in liquidating the underlying securities and losses, including possible decline in the value of the underlying security during the period in which the Fund seeks to enforce its rights thereto; possible lack of access to income on the underlying security during this period; and expenses of enforcing its rights. While repurchase agreements involve certain risks not associated with direct investments in fixed income securities, the Fund follows procedures approved by the Board that are designed to minimize such risks. In addition, the value of the collateral underlying the repurchase agreement will be at least equal to the repurchase price, including any accrued interest earned on the repurchase agreement. In the event of a default or bankruptcy by a selling financial institution, the Fund generally will seek to liquidate such collateral. However, the exercise of the Fund's right to liquidate such collateral could involve certain costs or delays and, to the extent that proceeds from any sale upon a default of the obligation to repurchase were less than the repurchase price, the Fund could suffer a loss.

Reverse Repurchase Agreements Risk. Reverse repurchase agreements involve the risks that the interest income earned on the investment of the proceeds will be less than the interest expense of the Fund, that the market value of the securities sold by the Fund may decline below the price at which the Fund is obligated to repurchase the securities and that the securities may not be returned to the Fund. There is no assurance that reverse repurchase agreements can be successfully employed.

Dollar Roll Transactions Risk. Dollar roll transactions involve the risk that the market value of the securities the Fund is required to purchase may decline below the agreed upon repurchase price of those securities. If the broker/dealer to whom the Fund sells securities becomes insolvent, the Fund's right to purchase or repurchase securities may be restricted. Successful use of dollar rolls may depend upon the Investment Advisor's ability to predict correctly interest rates and prepayments. There is no assurance that dollar rolls can be successfully employed. These transactions may involve leverage.

II-67

When-Issued, Forward Commitment and Delayed Delivery Transactions Risk. The Fund may purchase securities on a when-issued basis (including on a forward commitment or "TBA" (to be announced) basis) and may purchase or sell securities for delayed delivery. When-issued and delayed delivery transactions occur when securities are purchased or sold by the Fund with payment and delivery taking place in the future to secure an advantageous yield or price. Securities purchased on a when-issued or delayed delivery basis may expose the Fund to counterparty risk of default as well as the risk that securities may experience fluctuations in value prior to their actual delivery. The Fund will not accrue income with respect to a when-issued or delayed delivery security prior to its stated delivery date. Purchasing securities on a when-issued or delayed delivery basis can involve the additional risk that the price or yield available in the market when the delivery takes place may not be as favorable as that obtained in the transaction itself.

Strategic Transactions and Derivatives Risks. The Fund may engage in various Strategic Transactions for duration management and other risk management purposes, including to attempt to protect against possible changes in the market value of the Fund's portfolio resulting from trends in the securities markets and changes in interest rates or to protect the Fund's unrealized gains in the value of its portfolio securities, to facilitate the sale of portfolio securities for investment purposes or to establish a position in the securities markets as a temporary substitute for purchasing particular securities or, to the extent applicable, to enhance income or gain. Derivatives are financial contracts or instruments whose value depends on, or is derived from, the value of an underlying asset, reference rate or index (or relationship between two indices). The Fund also may use derivatives to add leverage to the portfolio and/or to hedge against increases in the Fund's costs associated with its leverage strategy. The use of Strategic Transactions to enhance current income may be particularly speculative.

Strategic Transactions. The risks associated with Strategic Transactions include (i) the imperfect correlation between the value of such instruments and the underlying assets, (ii) the possible default of the counterparty to the transaction, (iii) illiquidity of the derivative instruments, and (iv) high volatility losses caused by unanticipated market movements, which are potentially unlimited. Although both over-the-counter and exchange-traded derivatives markets may experience the lack of liquidity, over-the-counter non-standardized derivative transactions are generally less liquid than exchange-traded instruments. Furthermore, the Fund's ability to successfully use Strategic Transactions depends on the Investment Advisor's ability to predict pertinent securities prices, interest rates, currency exchange rates and other economic factors, which cannot be assured. The use of Strategic Transactions may result in losses greater than if they had not been used, may require the Fund to sell or purchase portfolio securities at inopportune times or for prices other than current market values, may limit the amount of appreciation the Fund can realize on an investment or may cause the Fund to hold a security that it might otherwise sell. Additionally, liquid assets designated on the Fund's books and records, amounts paid by the Fund as premiums and cash or other assets held in margin accounts with respect to Strategic Transactions are not otherwise available to the Fund for investment purposes.

While hedging can reduce or eliminate losses, it can also reduce or eliminate gains. Hedges are sometimes subject to imperfect matching between the derivative and the underlying security, and there can be no assurance that the Fund's hedging transactions will be effective.

Derivatives may give rise to a form of leverage and may expose the Fund to greater risk and increase its costs. Recent legislation calls for new regulation of the derivatives markets. The extent and impact of the regulation is not yet known and may not be known for some time. New regulation may make derivatives more costly, may limit the availability of derivatives, or may otherwise adversely affect the value or performance of derivatives.

The Fund's use of derivative instruments involves risks different from, and possibly greater than, the risks associated with investing directly in securities and other traditional investments. Derivatives are subject to a number of risks such as credit risk, leverage risk, liquidity risk, correlation risk and index risk as described below:

Credit Risk—the risk that the counterparty in a derivative transaction will be unable to honor its financial obligation to the Fund, or the risk that the reference entity in a derivative will not be able to honor its financial obligations. In particular, derivatives traded in over-the-counter ("OTC") markets often are not guaranteed by an exchange or clearing corporation and often do not require payment of margin, and to the extent that the Fund has unrealized gains in such instruments or has deposited

II-68

collateral with its counterparties the Fund is at risk that its counterparties will become bankrupt or otherwise fail to honor its obligations.

Currency Risk—the risk that changes in the exchange rate between two currencies will adversely affect the value (in U.S. dollar terms) of an investment.

Leverage Risk—the risk associated with certain types of investments or trading strategies (such as, for example, borrowing money to increase the amount of investments) that relatively small market movements may result in large changes in the value of an investment. Certain transactions in derivatives (such as futures transactions or sales of put options) involve substantial leverage risk and may expose the Fund to potential losses that exceed the amount originally invested by the Fund. When the Fund engages in such a transaction, the Fund will designate on its books and records liquid assets with a value at least equal to the Fund's exposure, on a mark-to-market basis, to the transaction (as calculated pursuant to requirements of the SEC). Such designation will ensure that the Fund has assets available to satisfy its obligations with respect to the transaction, but will not limit the Fund's exposure to loss.

Liquidity Risk—the risk that certain securities may be difficult or impossible to sell at the time that the Fund would like or at the price that the Fund as seller believes the security is currently worth. There can be no assurance that, at any specific time, either a liquid secondary market will exist for a derivative or the Fund will otherwise be able to sell such instrument at an acceptable price. It may, therefore, not be possible to close a position in a derivative without incurring substantial losses, if at all. The absence of liquidity may also make it more difficult for the Fund to ascertain a market value for such instruments. Although both OTC and exchange-traded derivatives markets may experience a lack of liquidity, certain derivatives traded in OTC markets, including indexed securities, swaps and OTC options, involve substantial liquidity risk. The illiquidity of the derivatives markets may be due to various factors, including congestion, disorderly markets, limitations on deliverable supplies, the participation of speculators, government regulation and intervention, and technical and operational or system failures. In addition, the liquidity of a secondary market in an exchange-traded derivative contract may be adversely affected by "daily price fluctuation limits" established by the exchanges that limit the amount of fluctuation in an exchange-traded contract price during a single trading day. Once the daily limit has been reached in the contract, no trades may be entered into at a price beyond the limit, thus preventing the liquidation of open positions. Prices have in the past moved beyond the daily limit on a number of consecutive trading days. If it is not possible to close an open derivative position entered into by the Fund, the Fund would continue to be required to make daily cash payments of variation margin in the event of adverse price movements. In such a situation, if the Fund has insufficient cash, it may have to sell portfolio securities to meet daily variation margin requirements at a time when it may be disadvantageous to do so.

Correlation Risk—the risk that changes in the value of a derivative will not match the changes in the value of the portfolio holdings that are being hedged or of the particular market or security to which the Fund seeks exposure through the use of the derivative. There are a number of factors which may prevent a derivative instrument from achieving the desired correlation (or inverse correlation) with an underlying asset, rate or index, such as the impact of fees, expenses and transaction costs, the timing of pricing, and disruptions or illiquidity in the markets for such derivative instrument.

Index Risk—If the derivative is linked to the performance of an index, it will be subject to the risks associated with changes in that index. If the index changes, the Fund could receive lower interest payments or experience a reduction in the value of the derivative to below the price that the Fund paid for such derivative. Certain indexed securities, including inverse securities (which move in an opposite direction to the index), may create leverage, to the extent that they increase or decrease in value at a rate that is a multiple of the changes in the applicable index.

Volatility Risk—the risk that the Fund's use of derivatives may reduce income or gain and/or increase volatility. Volatility is defined as the characteristic of a security, an index or a market to fluctuate

II-69

significantly in price over a defined time period. The Fund could suffer losses related to its derivative positions as a result of unanticipated market movements, which losses are potentially unlimited.

When a derivative is used as a hedge against a position that the Fund holds, any loss generated by the derivative generally should be substantially offset by gains on the hedged investment, and vice versa. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains. Hedges are sometimes subject to imperfect matching between the derivative and the underlying security, and there can be no assurance that the Fund's hedging transactions will be effective. The Fund could also suffer losses related to its derivative positions as a result of unanticipated market movements, which losses are potentially unlimited. The Investment Advisor may not be able to predict correctly the direction of securities prices, interest rates and other economic factors, which could cause the Fund's derivatives positions to lose value. In addition, some derivatives are more sensitive to interest rate changes and market price fluctuations than other securities. The possible lack of a liquid secondary market for derivatives and the resulting inability of the Fund to sell or otherwise close a derivatives position could expose the Fund to losses and could make derivatives more difficult for the Fund to value accurately.

When engaging in a hedging transaction, the Fund may determine not to seek to establish a perfect correlation between the hedging instruments utilized and the portfolio holdings being hedged. Such an imperfect correlation may prevent the Fund from achieving the intended hedge or expose the Fund to a risk of loss. The Fund may also determine not to hedge against a particular risk because it does not regard the probability of the risk occurring to be sufficiently high as to justify the cost of the hedge or because it does not foresee the occurrence of the risk. It may not be possible for the Fund to hedge against a change or event at attractive prices or at a price sufficient to protect the assets of the Fund from the decline in value of the portfolio positions anticipated as a result of such change. The Fund may also be restricted in its ability to effectively manage the portion of its assets that are segregated or designated on its books and records to cover its obligations. In addition, it may not be possible to hedge at all against certain risks.

If the Fund invests in a derivative instrument it could lose more than the principal amount invested. Moreover, derivatives raise certain tax, legal, regulatory and accounting issues that may not be presented by investments in securities, and there is some risk that certain issues could be resolved in a manner that could adversely impact the performance of the Fund.

The Fund is not required to use derivatives or other portfolio strategies to seek to increase return or to seek to hedge its portfolio and may choose not to do so. Also, suitable derivative transactions may not be available in all circumstances and there can be no assurance that the Fund will engage in these transactions to reduce exposure to other risks when that would be beneficial. Although the Investment Advisor seeks to use derivatives to further the Fund's investment objective, there is no assurance that the use of derivatives will achieve this result.

Counterparty Risk. The Fund will be subject to credit risk with respect to the counterparties to the derivative contracts purchased by the Fund. Because derivative transactions in which the Fund may engage may involve instruments that are not traded on an exchange but are instead traded between counterparties based on contractual relationships, the Fund is subject to the risk that a counterparty will not perform its obligations under the related contracts. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Fund may experience significant delays in obtaining any recovery in bankruptcy or other reorganization proceedings. The Fund may obtain only a limited recovery, or may obtain no recovery, in such circumstances. Although the Fund intends to enter into transactions only with counterparties that the Investment Advisor believes to be creditworthy, there can be no assurance that, as a result, a counterparty will not default and that the Fund will not sustain a loss on a transaction. In the event of the counterparty's bankruptcy or insolvency, the Fund's collateral may be subject to the conflicting claims of the counterparty's creditors, and the Fund may be exposed to the risk of a court treating the Fund as a general unsecured creditor of the counterparty, rather than as the owner of the collateral.

The counterparty risk for cleared derivatives is generally lower than for uncleared over-the-counter derivative transactions since generally a clearing organization becomes substituted for each counterparty to a cleared derivative contract and, in effect, guarantees the parties' performance under the contract as each party to a trade looks only to the clearing organization for performance of financial obligations under the derivative contract. However, there can be no assurance that a clearing organization, or its members, will satisfy its obligations to the Fund.

II-70

In addition, the Fund is subject to the risk that issuers of the instruments in which it invests and trades may default on their obligations under those instruments, and that certain events may occur that have an immediate and significant adverse effect on the value of those instruments. There can be no assurance that an issuer of an instrument in which the Fund invests will not default, or that an event that has an immediate and significant adverse effect on the value of an instrument will not occur, and that the Fund will not sustain a loss on a transaction as a result.

Swaps Risk. Swaps are types of derivatives. Swap agreements involve the risk that the party with which the Fund has entered into the swap will default on its obligation to pay the Fund and the risk that the Fund will not be able to meet its obligations to pay the other party to the agreement. In order to seek to hedge the value of the Fund's portfolio, to hedge against increases in the Fund's cost associated with the interest payments on its outstanding borrowings or, to the extent applicable, to seek to increase the Fund's return, the Fund may enter into swaps, including interest rate swap, total return swap or credit default swap transactions. In interest rate swap transactions, there is a risk that yields will move in the direction opposite of the direction anticipated by the Fund, which would cause the Fund to make payments to its counterparty in the transaction that could adversely affect Fund performance. In addition to the risks applicable to swaps generally (including counterparty risk, liquidity risk and credit risk), credit default swap transactions involve special risks because they are difficult to value, are highly susceptible to liquidity and credit risk, and generally pay a return to the party that has paid the premium only in the event of an actual default by the issuer of the underlying obligation (as opposed to a credit downgrade or other indication of financial difficulty). Total return swap agreements may effectively add leverage to the Fund's portfolio because, in addition to its Managed Assets, the Fund would be subject to investment exposure on the notional amount of the swap. Total return swap agreements are subject to the risk that a counterparty will default on its payment obligations to the Fund thereunder. The Fund is not required to enter into swap transactions for hedging purposes or to enhance income or gain and may choose not to do so. In addition, the swaps market is subject to a changing regulatory environment. It is possible that regulatory or other developments in the swaps market could adversely affect the Fund's ability to successfully use swaps.

Options Risk. There are several risks associated with transactions in options on securities and indexes. For example, there are significant differences between the securities and options markets that could result in an imperfect correlation between these markets, causing a given transaction not to achieve its objectives. In addition, a liquid secondary market for particular options, whether traded over-the-counter or on a national securities exchange ("Exchange") may be absent for reasons which include the following: there may be insufficient trading interest in certain options; restrictions may be imposed by an Exchange on opening transactions or closing transactions or both; trading halts, suspensions or other restrictions may be imposed with respect to particular classes or series of options or underlying securities; unusual or unforeseen circumstances may interrupt normal operations on an Exchange; the facilities of an Exchange or the OCC may not at all times be adequate to handle current trading volume; or one or more Exchanges could, for economic or other reasons, decide or be compelled at some future date to discontinue the trading of options (or a particular class or series of options), in which event the secondary market on that Exchange (or in that class or series of options) would cease to exist, although outstanding options that had been issued by the OCC as a result of trades on that Exchange would continue to be exercisable in accordance with their terms.

Futures Transactions and Options Risk. The primary risks associated with the use of futures contracts and options are (a) the imperfect correlation between the change in market value of the instruments held by the Fund and the price of the futures contract or option; (b) possible lack of a liquid secondary market for a futures contract and the resulting inability to close a futures contract when desired; (c) losses caused by unanticipated market movements, which are potentially unlimited; (d) the Investment Advisor's inability to predict correctly the direction of securities prices, interest rates, currency exchange rates and other economic factors; and (e) the possibility that the counterparty will default in the performance of its obligations.

Investment in futures contracts involves the risk of imperfect correlation between movements in the price of the futures contract and the price of the security being hedged. The hedge will not be fully effective when there is imperfect correlation between the movements in the prices of two financial instruments. For example, if the price of the futures contract moves more or less than the price of the hedged security, the Fund will experience either a loss or gain on the futures contract which is not completely offset by movements in the price of the hedged securities. To compensate for imperfect correlations, the Fund may purchase or sell futures contracts in a greater dollar amount than the hedged securities if the volatility of the hedged securities is historically greater than the volatility of the

II-71

futures contracts. Conversely, the Fund may purchase or sell fewer futures contracts if the volatility of the price of the hedged securities is historically lower than that of the futures contracts.

The particular securities comprising the index underlying a securities index financial futures contract may vary from the securities held by the Fund. As a result, the Fund's ability to hedge effectively all or a portion of the value of its securities through the use of such financial futures contracts will depend in part on the degree to which price movements in the index underlying the financial futures contract correlate with the price movements of the securities held by the Fund. The correlation may be affected by disparities in the average maturity, ratings, geographical mix or structure of the Fund's investments as compared to those comprising the securities index and general economic or political factors. In addition, the correlation between movements in the value of the securities index may be subject to change over time as additions to and deletions from the securities index alter its structure. The correlation between futures contracts on U.S. Government securities and the securities held by the Fund may be adversely affected by similar factors and the risk of imperfect correlation between movements in the prices of such futures contracts and the prices of securities held by the Fund may be greater. The trading of futures contracts also is subject to certain market risks, such as inadequate trading activity, which could at times make it difficult or impossible to liquidate existing positions.

The Fund may liquidate futures contracts it enters into through offsetting transactions on the applicable contract market. There can be no assurance, however, that a liquid secondary market will exist for any particular futures contract at any specific time. Thus, it may not be possible to close out a futures position. In the event of adverse price movements, the Fund would continue to be required to make daily cash payments of variation margin. In such situations, if the Fund has insufficient cash, it may be required to sell portfolio securities to meet daily variation margin requirements at a time when it may be disadvantageous to do so. The inability to close out futures positions also could have an adverse impact on the Fund's ability to hedge effectively its investments in securities. The liquidity of a secondary market in a futures contract may be adversely affected by "daily price fluctuation limits" established by commodity exchanges that limit the amount of fluctuation in a futures contract price during a single trading day. Once the daily limit has been reached in the contract, no trades may be entered into at a price beyond the limit, thus preventing the liquidation of open futures positions. Prices have in the past moved beyond the daily limit on a number of consecutive trading days.

The successful use of transactions in futures and related options also depends on the ability of the Investment Advisor to forecast correctly the direction and extent of interest rate movements within a given time frame. To the extent interest rates remain stable during the period in which a futures contract or option is held by the Fund or such rates move in a direction opposite to that anticipated, the Fund may realize a loss on the strategic transaction which is not fully or partially offset by an increase in the value of portfolio securities. As a result, the Fund's total return for such period may be less than if it had not engaged in the strategic transaction.

Because of low initial margin deposits made upon the opening of a futures position, futures transactions involve substantial leverage. As a result, relatively small movements in the price of the futures contracts can result in substantial unrealized gains or losses. There is also the risk of loss by the Fund of margin deposits in the event of bankruptcy of a broker with which the Fund has an open position in a financial futures contract. Because the Fund will engage in the purchase and sale of futures contracts for hedging purposes or to seek to enhance the Fund's return, any losses incurred in connection therewith may, if the strategy is successful, be offset in whole or in part by increases in the value of securities held by the Fund or decreases in the price of securities the Fund intends to acquire.

General Risk Factors in Hedging Foreign Currency. Hedging transactions involving Currency Instruments involve substantial risks, including correlation risk. While the Fund's use of Currency Instruments to effect hedging strategies is intended to reduce the volatility of the NAV of the Fund's common shares, the NAV of the Fund's common shares will fluctuate. Moreover, although Currency Instruments may be used with the intention of hedging against adverse currency movements, transactions in Currency Instruments involve the risk that anticipated currency movements will not be accurately predicted and that the Fund's hedging strategies will be ineffective. To the extent that the Fund hedges against anticipated currency movements that do not occur, the Fund may realize losses and decrease its total return as the result of its hedging transactions. Furthermore, the Fund will only engage in hedging activities from time to time and may not be engaging in hedging activities when movements in currency exchange rates occur.

II-72

It may not be possible for the Fund to hedge against currency exchange rate movements, even if correctly anticipated, in the event that (i) the currency exchange rate movement is so generally anticipated that the Fund is not able to enter into a hedging transaction at an effective price, or (ii) the currency exchange rate movement relates to a market with respect to which Currency Instruments are not available and it is not possible to engage in effective foreign currency hedging. The cost to the Fund of engaging in foreign currency transactions varies with such factors as the currencies involved, the length of the contract period and the market conditions then prevailing. Since transactions in foreign currency exchange usually are conducted on a principal basis, no fees or commissions are involved.

Foreign Currency Forwards Risk. Forward foreign currency exchange contracts do not eliminate fluctuations in the value of Non-U.S. Securities but rather allow the Fund to establish a fixed rate of exchange for a future point in time. This strategy can have the effect of reducing returns and minimizing opportunities for gain.

In connection with its trading in forward foreign currency contracts, the Fund will contract with a foreign or domestic bank, or foreign or domestic securities dealer, to make or take future delivery of a specified amount of a particular currency. There are no limitations on daily price moves in such forward contracts, and banks and dealers are not required to continue to make markets in such contracts. There have been periods during which certain banks or dealers have refused to quote prices for such forward contracts or have quoted prices with an unusually wide spread between the price at which the bank or dealer is prepared to buy and that at which it is prepared to sell. Governmental imposition of credit controls might limit any such forward contract trading. With respect to its trading of forward contracts, if any, the Fund will be subject to the risk of bank or dealer failure and the inability of, or refusal by, a bank or dealer to perform with respect to such contracts. Any such default would deprive the Fund of any profit potential or force the Fund to cover its commitments for resale, if any, at the then market price and could result in a loss to the Fund.

The Fund may also engage in proxy hedging transactions to reduce the effect of currency fluctuations on the value of existing or anticipated holdings of portfolio securities. Proxy hedging is often used when the currency to which the Fund is exposed is difficult to hedge or to hedge against the dollar. Proxy hedging entails entering into a forward contract to sell a currency whose changes in value are generally considered to be linked to a currency or currencies in which some or all of the Fund's securities are, or are expected to be, denominated, and to buy U.S. dollars. Proxy hedging involves some of the same risks and considerations as other transactions with similar instruments. Currency transactions can result in losses to the Fund if the currency being hedged fluctuates in value to a degree or in a direction that is not anticipated. In addition, there is the risk that the perceived linkage between various currencies may not be present or may not be present during the particular time that the Fund is engaging in proxy hedging. The Fund may also cross-hedge currencies by entering into forward contracts to sell one or more currencies that are expected to decline in value relative to other currencies to which the Fund has or in which the Fund expects to have portfolio exposure. For example, the Fund may hold both Canadian government bonds and Japanese government bonds, and the Investment Advisor may believe that Canadian dollars will deteriorate against Japanese yen. The Fund would sell Canadian dollars to reduce its exposure to that currency and buy Japanese yen. This strategy would be a hedge against a decline in the value of Canadian dollars, although it would expose the Fund to declines in the value of the Japanese yen relative to the U.S. dollar.

Some of the forward non-U.S. currency contracts entered into by the Fund may be classified as non-deliverable forwards ("NDFs"). NDFs are cash-settled, short-term forward contracts that may be thinly traded or are denominated in non-convertible foreign currency, where the profit or loss at the time at the settlement date is calculated by taking the difference between the agreed upon exchange rate and the spot rate at the time of settlement, for an agreed upon notional amount of funds. All NDFs have a fixing date and a settlement date. The fixing date is the date at which the difference between the prevailing market exchange rate and the agreed upon exchange rate is calculated. The settlement date is the date by which the payment of the difference is due to the party receiving payment. NDFs are commonly quoted for time periods of one month up to two years, and are normally quoted and settled in U.S. dollars. They are often used to gain exposure to and/or hedge exposure to foreign currencies that are not internationally traded.

Currency Futures Risk. The Fund may also seek to hedge against the decline in the value of a currency or, to the extent applicable, to enhance returns, through use of currency futures or options thereon. Currency futures are similar to forward foreign exchange transactions except that futures are standardized, exchange-traded contracts

II-73

while forward foreign exchange transactions are traded in the OTC market. Currency futures involve substantial currency risk, and also involve leverage risk.

Currency Options Risk. The Fund may also seek to hedge against the decline in the value of a currency or, to the extent applicable, to enhance returns, through the use of currency options. Currency options are similar to options on securities. For example, in consideration for an option premium the writer of a currency option is obligated to sell (in the case of a call option) or purchase (in the case of a put option) a specified amount of a specified currency on or before the expiration date for a specified amount of another currency. The Fund may engage in transactions in options on currencies either on exchanges or OTC markets. Currency options involve substantial currency risk, and may also involve credit, leverage or liquidity risk.

Currency Swaps Risk. In order to protect against currency fluctuations, the Fund may enter into currency swaps. The Fund may also hedge portfolio positions through currency swaps, which are transactions in which one currency is simultaneously bought for a second currency on a spot basis and sold for the second currency on a forward basis. Currency swaps involve the exchange of the rights of the Fund and another party to make or receive payments in specified currencies. Currency swaps usually involve the delivery of the entire principal value of one designated currency in exchange for the other designated currency. Because currency swaps usually involve the delivery of the entire principal value of one designated currency in exchange for the other designated currency, the entire principal value of a currency swap is subject to the risk that the other party to the swap will default on its contractual delivery obligations.

Over-the-Counter Trading Risk. The derivative instruments that may be purchased or sold by the Fund may include instruments not traded on an exchange. The risk of nonperformance by the counterparty to an instrument may be greater than, and the ease with which the Fund can dispose of or enter into closing transactions with respect to an instrument may be less than, the risk associated with an exchange traded instrument. In addition, significant disparities may exist between "bid" and "asked" prices for derivative instruments that are not traded on an exchange. The absence of liquidity may make it difficult or impossible for the Fund to sell such instruments promptly at an acceptable price. Derivative instruments not traded on exchanges also are not subject to the same type of government regulation as exchange traded instruments, and many of the protections afforded to participants in a regulated environment may not be available in connection with the transactions. Because derivatives traded in OTC markets generally are not guaranteed by an exchange or clearing corporation and generally do not require payment of margin, to the extent that the Fund has unrealized gains in such instruments or has deposited collateral with its counterparties the Fund is at risk that its counterparties will become bankrupt or otherwise fail to honor its obligations.

Clearing Broker and Central Clearing Counterparty Risks. The CEA requires swaps and futures clearing brokers registered as "futures commission merchants" to segregate all funds received from customers with respect to any orders for the purchase or sale of U.S. domestic futures contracts and cleared swaps from the brokers' proprietary assets. Similarly, the CEA requires each futures commission merchant to hold in a separate secure account all funds received from customers with respect to any orders for the purchase or sale of foreign futures contracts and segregate any such funds from the funds received with respect to domestic futures contracts. However, all funds and other property received by a clearing broker from its customers are held by the clearing broker on a commingled basis in an omnibus account and may be freely accessed by the clearing broker, which may also invest any such funds in certain instruments permitted under the applicable regulations. There is a risk that assets deposited by the Fund with any swaps or futures clearing broker as margin for futures contracts or cleared swaps may, in certain circumstances, be used to satisfy losses of other clients of the Fund's clearing broker. In addition, the assets of the Fund might not be fully protected in the event of the Fund's clearing broker's bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing broker's combined domestic customer accounts.

Similarly, the CEA requires a clearing organization approved by the CFTC as a derivatives clearing organization to segregate all funds and other property received from a clearing member's clients in connection with domestic futures and options contracts from any funds held at the clearing organization to support the clearing member's proprietary trading. Nevertheless, all customer funds held at a clearing organization in connection with any futures or options contracts are held in a commingled omnibus account and are not identified to the name of the clearing member's individual customers. With respect to futures and options contracts, a clearing organization may use assets of a non-defaulting customer held in an omnibus account at the clearing organization to satisfy payment

II-74

obligations of a defaulting customer of the clearing member to the clearing organization. As a result, in the event of a default of the clearing broker's other clients or the clearing broker's failure to extend its own funds in connection with any such default, the Fund would not be able to recover the full amount of assets deposited by the clearing broker on behalf of the Fund with the clearing organization.

Dodd-Frank Act Risk. Title VII of the Dodd-Frank Act (the "Derivatives Title") imposes a new regulatory structure on derivatives markets, with particular emphasis on swaps and security-based swaps (collectively "swaps"). This new regulatory framework covers a broad range of swap market participants, including banks, non-banks, credit unions, insurance companies, broker-dealers and investment advisers. The SEC, other U.S. regulators, and to a lesser extent the CFTC (the "Regulators") still are in the process of adopting regulations to implement the Derivatives Title, though certain aspects of the new regulatory structure are substantially complete. Until the Regulators complete their rulemaking efforts, the full extent to which the Derivatives Title and the rules adopted thereunder will impact the Fund is unclear. It is possible that the continued development of this new regulatory structure for swaps may jeopardize certain trades and/or trading strategies that may be employed by the Investment Advisor, or at least make them more costly.

Recently, new regulations have required the mandatory central clearing and mandatory exchange trading of particular types of interest rate swaps and index credit default swaps (together, "Covered Swaps"). Together, these new regulatory requirements change the Fund's trading of Covered Swaps. With respect to mandatory central clearing, the Fund is now required to clear its Covered Swaps through a clearing broker, which requires, among other things, posting initial margin and variation margin to the Fund's clearing broker in order to enter into and maintain positions in Covered Swaps. With respect to mandatory exchange trading, the Investment Advisor may be required to become a participant of a new type of execution platform called a swap execution facility ("SEF") or may be required to access the SEF through an intermediary (such as an executing broker) in order to be able to trade Covered Swaps for the Fund. In either scenario, the Investment Advisor and/or the Fund may incur additional legal and compliance costs and transaction fees. Just as with the other regulatory changes imposed as a result of the implementation of the Derivatives Title, the increased costs and fees associated with trading Covered Swaps may jeopardize certain trades and/or trading strategies that may be employed by the Investment Advisor, or at least make them more costly.

Additionally, the Regulators plan to finalize proposed regulations that would require swap dealers to collect from the Fund initial margin and variation margin for uncleared derivatives transactions and that would impose upon swap dealers new capital requirements. These requirements, when finalized, may make certain types of trades and/or trading strategies more costly or impermissible.

There may be market dislocations due to uncertainty during the implementation period of any new regulation and the Investment Advisor cannot know how the derivatives market will adjust to new regulations. Until the Regulators complete the rulemaking process for the Derivatives Title, it is unknown the extent to which such risks may materialize.

Legal and Regulatory Risk. At any time after the date hereof, legislation or additional regulations may be enacted that could negatively affect the assets of the Fund. Changing approaches to regulation may have a negative impact on the securities in which the Fund invests. Legislation or regulation may also change the way in which the Fund itself is regulated. There can be no assurance that future legislation, regulation or deregulation will not have a material adverse effect on the Fund or will not impair the ability of the Fund to achieve its investment objective. In addition, as new rules and regulations resulting from the passage of the Dodd-Frank Act are implemented and new international capital and liquidity requirements are introduced under the Basel III Accords ("Basel III"), the market may not react the way the Investment Advisor expects. Whether the Fund achieves its investment objective may depend on, among other things, whether the Investment Advisor correctly forecasts market reactions to this and other legislation. In the event the Investment Advisor incorrectly forecasts market reaction, the Fund may not achieve its investment objective.

Securities Lending Risk. The Fund may lend securities to financial institutions. Securities lending involves exposure to certain risks, including operational risk (i.e., the risk of losses resulting from problems in the settlement and accounting process), "gap" risk (i.e., the risk of a mismatch between the return on cash collateral reinvestments and the fees the Fund has agreed to pay a borrower), and credit, legal, counterparty and market risk. If a securities lending counterparty were to default, the Fund would be subject to the risk of a possible delay in receiving collateral

II-75

or in recovering the loaned securities, or to a possible loss of rights in the collateral. In the event a borrower does not return the Fund's securities as agreed, the Fund may experience losses if the proceeds received from liquidating the collateral do not at least equal the value of the loaned security at the time the collateral is liquidated, plus the transaction costs incurred in purchasing replacement securities. This event could trigger adverse tax consequences for the Fund. The Fund could lose money if its short-term investment of the collateral declines in value over the period of the loan. Substitute payments for dividends received by the Fund for securities loaned out by the Fund will not be considered qualified dividend income. The securities lending agent will take the tax effects on shareholders of this difference into account in connection with the Fund's securities lending program. Substitute payments received on tax-exempt securities loaned out will not be tax-exempt income.

Short Selling Risk. Short-selling involves selling securities which may or may not be owned and borrowing the same securities for delivery to the purchaser, with an obligation to replace the borrowed securities at a later date. If the price of the security sold short increases between the time of the short sale and the time the Fund replaces the borrowed security, the Fund will incur a loss; conversely, if the price declines, the Fund will realize a capital gain. Any gain will be decreased, and any loss will be increased, by the transaction costs incurred by the Fund, including the costs associated with providing collateral to the broker-dealer (usually cash and liquid securities) and the maintenance of collateral with its custodian. Although the Fund's gain is limited to the price at which it sold the security short, its potential loss is theoretically unlimited.

Short-selling necessarily involves certain additional risks. However, if the short seller does not own the securities sold short (an uncovered short sale), the borrowed securities must be replaced by securities purchased at market prices in order to close out the short position, and any appreciation in the price of the borrowed securities would result in a loss. Uncovered short sales expose the Fund to the risk of uncapped losses until a position can be closed out due to the lack of an upper limit on the price to which a security may rise. Purchasing securities to close out the short position can itself cause the price of the securities to rise further, thereby exacerbating the loss. There is the risk that the securities borrowed by the Fund in connection with a short-sale must be returned to the securities lender on short notice. If a request for return of borrowed securities occurs at a time when other short-sellers of the security are receiving similar requests, a "short squeeze" can occur, and the Fund may be compelled to replace borrowed securities previously sold short with purchases on the open market at the most disadvantageous time, possibly at prices significantly in excess of the proceeds received at the time the securities were originally sold short.

In September 2008, in response to spreading turmoil in the financial markets, the SEC temporarily banned short selling in the stocks of numerous financial services companies, and also promulgated new disclosure requirements with respect to short positions held by investment managers. The SEC's temporary ban on short selling of such stocks has since expired, but should similar restrictions and/or additional disclosure requirements be promulgated, especially if market turmoil occurs, the Fund may be forced to cover short positions more quickly than otherwise intended and may suffer losses as a result. Such restrictions may also adversely affect the ability of the Fund to execute its investment strategies generally. Similar emergency orders have also recently been instituted in non-U.S. markets in response to increased volatility. The SEC recently adopted amendments to Regulation SHO under the Securities Exchange Act of 1934 (the "Exchange Act") that restrict the ability to engage in a short sale at a price that is less than or equal to the current best bid if the price of the covered security has decreased by 10% or more from the covered security's closing price as of the end of the prior day.

Inflation Risk. Inflation risk is the risk that the value of assets or income from investment will be worth less in the future, as inflation decreases the value of money. As inflation increases, the real value of the common shares and distributions on those shares can decline. In addition, during any periods of rising inflation, interest rates on any borrowings by the Fund would likely increase, which would tend to further reduce returns to the holders of common shares.

Deflation Risk. Deflation risk is the risk that prices throughout the economy decline over time, which may have an adverse effect on the market valuation of companies, their assets and their revenues. In addition, deflation may have an adverse effect on the creditworthiness of issuers and may make issuer default more likely, which may result in a decline in the value of the Fund's portfolio.

Risks Associated with Recent Market Events. In the recent past, the debt and equity capital markets in the United States were negatively impacted by significant write-offs in the financial services sector relating to sub-prime mortgages and the repricing of credit risk in the broadly syndicated market, among other things. These events, along

II-76

with the downgrade to the United States credit rating, deterioration of the housing market, the failure of major financial institutions and the resulting United States federal government actions led in the recent past, and may lead in the future, to worsening general economic conditions, which did, and could, materially and adversely impact the broader financial and credit markets and reduce the availability of debt and equity capital for the market as a whole and financial firms in particular. These events adversely affected (and could adversely affect in the future) the willingness of some lenders to extend credit in general, which may have made it (and could make it in the future) more difficult for issuers of fixed income securities to obtain financings or refinancings for their investment or lending activities or operations. There is a risk that such issuers would be unable to successfully complete such financings or refinancings. In particular, because of the current conditions in the credit markets, issuers of fixed income securities may be subject to increased cost for debt, tightening underwriting standards and reduced liquidity for loans they make, securities they purchase and securities they issue. These events may increase the volatility of the value of securities owned by the Fund and/or result in sudden and significant valuation increases or decreases in its portfolio. These events also may make it more difficult for the Fund to accurately value its securities or to sell its securities on a timely basis. In addition, illiquidity and volatility in the credit markets may directly and adversely affect the setting of dividend rates on the common shares. These events adversely affected the broader economy, and may continue to do so, which may adversely affect the ability of issuers of securities owned by the Fund to make payments of principal and interest when due, lead to lower credit ratings and increase defaults. There is also a risk that developments in sectors of the credit markets in which the Fund does not invest may adversely affect the liquidity and the value of securities in sectors of the credit markets in which the Fund does invest, including securities owned by Fund.

While the extreme volatility and disruption that U.S. and global markets experienced for an extended period of time beginning in 2007 and 2008 has generally subsided, uncertainty and periods of volatility remain, and risks to a robust resumption of growth persist. In 2010, several EU countries, including Greece, Ireland, Italy, Spain and Portugal, began to face budget issues, some of which may have negative long-term effects for the economies of those countries and other EU countries. There is continued concern about national-level support for the Euro and the accompanying coordination of fiscal and wage policy among EMU member countries. Recent downgrades to the credit ratings of major banks could result in increased borrowing costs for such banks and negatively affect the broader economy. Moreover, Federal Reserve policy, including with respect to certain interest rates and the decision to begin tapering its quantitative easing policy, may adversely affect the value, volatility and liquidity of dividend and interest paying securities. Market volatility, rising interest rates and/or a return to unfavorable economic conditions could impair the Fund's ability to achieve its investment objective.

General market uncertainty and consequent repricing of risk have led to market imbalances of sellers and buyers, which in turn have resulted in significant valuation uncertainties in a variety of securities and significant and rapid value decline in certain instances. Additionally, periods of market volatility remain, and may continue to occur in the future, in response to various political, social and economic events both within and outside of the United States. These conditions resulted in, and in many cases continue to result in, greater price volatility, less liquidity, widening credit spreads and a lack of price transparency, with many securities remaining illiquid and of uncertain value. Such market conditions may make valuation of some of the Fund's securities uncertain and/or result in sudden and significant valuation increases or declines in its holdings. If there is a significant decline in the value of the Fund's portfolio, this may impact the asset coverage levels for the Fund's outstanding leverage.

EMU and Redenomination Risk. As the European debt crisis has progressed the possibility of one or more Eurozone countries exiting the EMU, or even the collapse of the Euro as a common currency, has arisen, creating significant volatility at times in currency and financial markets generally. The effects of the collapse of the Euro, or of the exit of one or more countries from the EMU, on the U.S. and global economy and securities markets are impossible to predict and any such events could have a significant adverse impact on the value and risk profile of the Fund's portfolio. Any partial or complete dissolution of the EMU could have significant adverse effects on currency and financial markets, and on the values of the Fund's portfolio investments. If one or more EMU countries were to stop using the Euro as its primary currency, the Fund's investments in such countries may be redenominated into a different or newly adopted currency. As a result, the value of those investments could decline significantly and unpredictably. In addition, securities or other investments that are redenominated may be subject to foreign currency risk, liquidity risk and valuation risk to a greater extent than similar investments currently denominated in Euros. To the extent a currency used for redenomination purposes is not specified in respect of certain EMU-related investments, or should the Euro cease to be used entirely, the currency in which such investments are denominated

II-77

may be unclear, making such investments particularly difficult to value or dispose of. The Fund may incur additional expenses to the extent it is required to seek judicial or other clarification of the denomination or value of such securities.

Market Disruption and Geopolitical Risk. The aftermath of the war in Iraq, instability in Afghanistan, Pakistan, Egypt, Libya, Syria and the Middle East, the ongoing epidemic of the Ebola virus disease in West Africa, possible terrorist attacks in the United States and around the world, growing social and political discord in the United States, the European debt crisis, further downgrades of U.S. Government securities and other similar events may result in market volatility, may have long-term effects on the U.S. and worldwide financial markets and may cause further economic uncertainties in the United States and worldwide. The Fund does not know how long the securities markets may be affected by these events and cannot predict the effects of these events or similar events in the future on the U.S. economy and securities markets. Non-investment grade and equity securities tend to be more volatile than investment grade fixed income securities; therefore these events and other market disruptions may have a greater impact on the prices and volatility of non-investment grade and equity securities than on investment grade fixed income securities. There can be no assurance that these events and other market disruptions will not have other material and adverse implications.

Regulation and Government Intervention Risk. The recent instability in the financial markets discussed above has led the U.S. Government and certain foreign governments to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility, and in some cases a lack of liquidity, including through direct purchases of equity and debt securities. Federal, state, and other governments, their regulatory agencies or self-regulatory organizations may take actions that affect the regulation of the issuers in which the Fund invests in ways that are unforeseeable. Legislation or regulation may also change the way in which the Fund is regulated. Such legislation or regulation could limit or preclude the Fund's ability to achieve its investment objective.

Congress has enacted sweeping financial legislation, the Dodd-Frank Act, signed into law by President Obama on July 21, 2010, regarding the operation of banks, private fund managers and other financial institutions, which includes provisions regarding the regulation of derivatives. Many provisions of the Dodd-Frank Act have been or will be implemented through regulatory rulemakings and similar processes over a period of time. The impact of the Dodd-Frank Act, and of follow-on regulation, on trading strategies and operations is impossible to predict, and may be adverse. Practices and areas of operation subject to significant change based on the impact, direct or indirect, of the Dodd-Frank Act and follow-on regulation, may change in manners that are unforeseeable, with uncertain effects. By way of example and not limitation, direct and indirect changes from the Dodd-Frank Act and follow-on regulation may occur to a significant degree with regard to, among other areas, financial consumer protection, bank ownership of and involvement with private funds, proprietary trading, registration of investment advisers, and the trading and use of many derivative instruments, including swaps. There can be no assurance that such legislation or regulation will not have a material adverse effect on the Fund. In addition, Congress may address tax policy, which also could have uncertain direct and indirect impacts on trading and operations, as well as, potentially, the operations and structure of the Fund.

Further, the Dodd-Frank Act created the Financial Stability Oversight Council ("FSOC"), an interagency body charged with identifying and monitoring systemic risks to financial markets. The FSOC has the authority to require that non-bank financial companies that are "predominantly engaged in financial activities," such as the Fund and the Investment Advisor, whose failure it determines would pose systemic risk, be placed under the supervision of the Board of Governors of the Federal Reserve System ("Federal Reserve"). The FSOC has the authority to recommend that the Federal Reserve adopt more stringent prudential standards and reporting and disclosure requirements for non-bank financial companies supervised by the Federal Reserve. The FSOC also has the authority to make recommendations to the Federal Reserve on various other matters that may affect the Fund, including requiring financial firms to submit resolution plans, mandating credit exposure reports, establishing concentration limits and limiting short-term debt. The FSOC may also recommend that other federal financial regulators impose more stringent regulation upon, or ban altogether, financial activities of any financial firm that poses what it determines are significant risks to the financial system. In the event that the FSOC designates the Fund or the Investment Advisor as a systemic risk to be placed under the Federal Reserve's supervision, the Fund or the Investment Advisor could face stricter prudential standards, including risk-based capital requirements, leverage limits, liquidity requirements, concentration requirements and overall risk management requirements, among other

II-78

restrictions. Such requirements could hinder the Fund's ability to meet its investment objective and may place the Fund at a disadvantage with respect to its competitors.

Additionally, BlackRock is, for purposes of the Bank Holding Company Act of 1956, as amended, and any rules or regulations promulgated thereunder from time to time, currently considered a subsidiary of The PNC Financial Services Group, Inc. ("PNC"), which is subject to regulation and supervision as a "financial holding company" by the Federal Reserve. The "Volcker Rule" contained in Section 619 of the Dodd-Frank Act will limit the ability of banking entities, which would include BlackRock by virtue of its relationship with PNC, to sponsor, invest in or serve as investment manager of certain private investment funds. On December 10, 2013, U.S. financial regulators adopted final regulations (the "Final Regulations") to implement the statutory mandate of the Volcker Rule. Pursuant to the Dodd-Frank Act, the Volcker Rule's effective date was July 21, 2012 and the Final Regulations become effective on April 14, 2014; however, concurrent with the adoption of the Final Regulations the Federal Reserve granted a statutorily permitted conformance period, essentially making the effective date of the Volcker Rule and the Final Regulations July 21, 2015. The Volcker Rule and the Final Regulations could have a significant negative impact on BlackRock and the Investment Advisor. BlackRock may attempt to take certain actions to lessen the impact of the Volcker Rule, although no assurance can be given that such actions would be successful and no assurance can be given that such actions would not have a significant negative impact on the Fund. Upon the end of the applicable conformance period, BlackRock's relationship with PNC may require BlackRock to curtail some or all of the Fund's activities with respect to PNC (if any).

The continuing implementation of the Dodd-Frank Act could also adversely affect the Investment Advisor and the Fund by increasing transaction and/or regulatory compliance costs. In addition, greater regulatory scrutiny and the implementation of enhanced and new regulatory requirements may increase the Investment Advisor' and the Fund's exposure to potential liabilities, and in particular liabilities arising from violating any such enhanced and/or new regulatory requirements. Increased regulatory oversight could also impose administrative burdens on the Investment Advisor and the Fund, including, without limitation, responding to investigations and implementing new policies and procedures. The ultimate impact of the Dodd-Frank Act, and any resulting regulation, is not yet certain and the Investment Advisor and the Fund may be affected by the new legislation and regulation in ways that are currently unforeseeable.

In connection with an ongoing review by the SEC and its staff of the regulation of investment companies' use of derivatives, on August 31, 2011 the SEC issued a concept release to seek public comment on a wide range of issues raised by the use of derivatives by investment companies. The SEC noted that it intends to consider the comments to help determine whether regulatory initiatives or guidance are needed to improve the current regulatory regime for investment companies and, if so, the nature of any such initiatives or guidance. While the nature of any such regulations is uncertain at this time, it is possible that such regulations could limit the implementation of the Fund's use of derivatives, which could have an adverse impact on the Fund. The Investment Advisor cannot predict the effects of these regulations on the Fund's portfolio. The Investment Advisor intends to monitor developments and seek to manage the Fund's portfolio in a manner consistent with achieving the Fund's investment objective, but there can be no assurance that it will be successful in doing so.

Certain lawmakers support an increase in federal revenue as a component of a plan to address the growing federal budget deficit. Also, comprehensive federal tax reform is the subject of political attention.

In the aftermath of the recent financial crisis, there appears to be a renewed popular, political and judicial focus on finance related consumer protection. Financial institution practices are also subject to greater scrutiny and criticism generally. In the case of transactions between financial institutions and the general public, there may be a greater tendency toward strict interpretation of terms and legal rights in favor of the consuming public, particularly where there is a real or perceived disparity in risk allocation and/or where consumers are perceived as not having had an opportunity to exercise informed consent to the transaction. In the event of conflicting interests between retail investors holding common shares of a closed-end investment company such as the Fund and a large financial institution, a court may similarly seek to strictly interpret terms and legal rights in favor of retail investors.

Legal, Tax and Regulatory Risks. Legal, tax and regulatory changes could occur that may materially adversely affect the Fund. For example, the regulatory and tax environment for derivative instruments in which the Fund may participate is evolving, and changes in the regulation or taxation of derivative instruments may materially

II-79

adversely affect the value of derivative instruments held by the Fund and the ability of the Fund to pursue its investment strategies.

To qualify for the favorable U.S. federal income tax treatment generally accorded to RICs, the Fund must, among other things, derive in each taxable year at least 90% of its gross income from certain prescribed sources and distribute for each taxable year at least 90% of its "investment company taxable income" (generally, ordinary income plus the excess, if any, of net short-term capital gain over net long-term capital loss). If for any taxable year the Fund does not qualify as a RIC, all of its taxable income for that year (including its net capital gain) would be subject to tax at regular corporate rates without any deduction for distributions to shareholders, and such distributions would be taxable as ordinary dividends to the extent of the Fund's current and accumulated earnings and profits.

1940 Act Regulation. The Fund is a registered closed-end investment company and as such is subject to regulations under the 1940 Act. Generally speaking, any contract or provision thereof that is made, or where performance involves a violation of the 1940 Act or any rule or regulation thereunder is unenforceable by either party unless a court finds otherwise.

Legislation Risk. At any time after the date of this Prospectus, legislation may be enacted that could negatively affect the assets of the Fund. Legislation or regulation may change the way in which the Fund itself is regulated. The Investment Advisor cannot predict the effects of any new governmental regulation that may be implemented and there can be no assurance that any new governmental regulation will not adversely affect the Fund's ability to achieve its investment objective.

Potential Conflicts of Interest of the Investment Advisor and Others. BlackRock, the ultimate parent company of the Investment Advisor, and its Affiliates (as defined in "Conflicts of Interest" under Item 20) are involved worldwide with a broad spectrum of financial services and asset management activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Fund. BlackRock and its Affiliates may provide investment management services to other funds and discretionary managed accounts that follow an investment program similar to that of the Fund. Subject to the requirements of the 1940 Act, BlackRock and its Affiliates intend to engage in such activities and may receive compensation from third parties for their services. Neither BlackRock nor its Affiliates are under any obligation to share any investment opportunity, idea or strategy with the Fund. As a result, BlackRock and its Affiliates may compete with the Fund for appropriate investment opportunities. The results of the Fund's investment activities, therefore, may differ from those of an Affiliate or another account managed by an Affiliate and it is possible that the Fund could sustain losses during periods in which one or more Affiliates and other accounts achieve profits on their trading for proprietary or other accounts. The 1940 Act imposes limitations on certain transactions between a registered investment company and affiliated persons of the investment company, as well as affiliated persons of such affiliated persons. Among others, affiliated persons of an investment company include its investment adviser; officers; directors/trustees; any person who directly or indirectly controls, is controlled by or is under common control with such investment company; any person directly or indirectly owning, controlling or holding with power to vote, five percent or more of the outstanding voting securities of such investment company; and any person five percent or more of whose outstanding voting securities are directly or indirectly owned, controlled or held with power to vote by such investment company. BlackRock has adopted policies and procedures designed to address potential conflicts of interests. For additional information about potential conflicts of interest and the way in which BlackRock addresses such conflicts, please see "Conflicts of Interest" in Item 20 of this Part II, "Conflicts of Interest" in Item 21.1 of Part I and "Potential Material Conflicts of Interest" in Item 21 of this Part II.

Decision-Making Authority Risk. Investors have no authority to make decisions or to exercise business discretion on behalf of the Fund, except as set forth in the Fund's governing documents. The authority for all such decisions is generally delegated to the Board, who in turn, has delegated the day-to-day management of the Fund's investment activities to the Investment Advisor, subject to oversight by the Board.

Management Risk. The Fund is subject to management risk because it is an actively managed investment portfolio. The Investment Advisor and the individual portfolio managers will apply investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these will produce the desired results. The Fund may be subject to a relatively high level of management risk because the Fund may invest

II-80

in derivative instruments, which may be highly specialized instruments that require investment techniques and risk analyses different from those associated with equities and bonds.

Market and Selection Risk. Market risk is the possibility that the market values of securities owned by the Fund will decline. There is a risk that equity and/or bond markets will go down in value, including the possibility that such markets will go down sharply and unpredictably.

The prices of fixed income securities tend to fall as interest rates rise, and such declines tend to be greater among fixed income securities with longer maturities. Market risk is often greater among certain types of fixed income securities, such as zero coupon bonds that do not make regular interest payments but are instead bought at a discount to their face values and paid in full upon maturity. As interest rates change, these securities often fluctuate more in price than securities that make regular interest payments and therefore subject the Fund to greater market risk than a fund that does not own these types of securities.

Stock markets are volatile, and the price of equity securities fluctuates based on changes in a company's financial condition and overall market and economic conditions. An adverse event, such as an unfavorable earnings report, may depress the value of a particular common stock held by the Fund. Also, the price of common stocks is sensitive to general movements in the stock market and a drop in the stock market may depress the price of common stocks to which the Fund has exposure. Common stock prices fluctuate for several reasons, including changes in investors' perceptions of the financial condition of an issuer or the general condition of the relevant stock market, or when political or economic events affecting the issuers occur.

When-issued and delayed delivery transactions are subject to changes in market conditions from the time of the commitment until settlement, which may adversely affect the prices or yields of the securities being purchased. The greater the Fund's outstanding commitments for these securities, the greater the Fund's exposure to market price fluctuations.

Selection risk is the risk that the securities that the Fund's management selects will underperform the equity and/or bond market, the market relevant indices or other funds with a similar investment objective and investment strategies.

Allocation Risk. The Fund's ability to achieve its investment objective depends upon the Investment Advisor's skill in determining the Fund's strategic asset class allocation and in selecting the best mix of investments. There is a risk that the Investment Advisor's evaluations and assumptions regarding asset classes or investments may be incorrect in view of actual market conditions.

The Fund's allocation of its investments across various segments of the securities markets and various countries, regions, asset classes and sectors may vary significantly over time based on the Investment Advisor's analysis and judgment. As a result, the particular risks most relevant to an investment in the Fund, as well as the overall risk profile of the Fund's portfolio, may vary over time. The Investment Advisor employs an active approach to the Fund's investment allocations, but there is no guarantee that the Investment Advisor's allocation strategy will produce the desired results. The percentage of the Fund's total assets allocated to any category of investment may at any given time be significantly less than the maximum percentage permitted pursuant to the Fund's investment policies. It is possible that the Fund will focus on an investment that performs poorly or underperforms other investments under various market conditions. The flexibility of the Fund's investment policies and the discretion granted to the Investment Advisor to invest the Fund's assets across various segments, classes and geographic regions of the securities markets and in securities with various characteristics means that the Fund's ability to achieve its investment objective may be more dependent on the success of its investment advisers than other investment companies.

Reliance on the Investment Advisor. The Fund is dependent upon services and resources provided by the Investment Advisor, and therefore the Investment Advisor's parent, BlackRock. The Investment Advisor is not required to devote its full time to the business of the Fund and there is no guarantee or requirement that any investment professional or other employee of the Investment Advisor will allocate a substantial portion of his or her time to the Fund. The loss of one or more individuals involved with the Investment Advisor could have a material adverse effect on the performance or the continued operation of the Fund.

II-81

Reliance on Service Providers. The Fund must rely upon the performance of service providers to perform certain functions, which may include functions that are integral to the Fund's operations and financial performance. Failure by any service provider to carry out its obligations to the Fund in accordance with the terms of its appointment, to exercise due care and skill or to perform its obligations to the Fund at all as a result of insolvency, bankruptcy or other causes could have a material adverse effect on the Fund's performance and returns to shareholders. The termination of the Fund's relationship with any service provider, or any delay in appointing a replacement for such service provider, could materially disrupt the business of the Fund and could have a material adverse effect on the Fund's performance and returns to shareholders.

Information Technology Systems. The Fund is dependent on the Investment Advisor for certain management services as well as back-office functions. The Investment Advisor depends on information technology systems in order to assess investment opportunities, strategies and markets and to monitor and control risks for the Fund. It is possible that a failure of some kind which causes disruptions to these information technology systems could materially limit the Investment Advisor's ability to adequately assess and adjust investments, formulate strategies and provide adequate risk control. Any such information technology-related difficulty could harm the performance of the Fund. Further, failure of the back-office functions of the Investment Advisor to process trades in a timely fashion could prejudice the investment performance of the Fund.

Misconduct of Employees and of Service Providers. Misconduct or misrepresentations by employees of the Investment Advisor or the Fund's service providers could cause significant losses to the Fund. Employee misconduct may include binding the Fund to transactions that exceed authorized limits or present unacceptable risks and unauthorized trading activities, concealing unsuccessful trading activities (which, in any case, may result in unknown and unmanaged risks or losses) or making misrepresentations regarding any of the foregoing. Losses could also result from actions by the Fund's service providers, including, without limitation, failing to recognize trades and misappropriating assets. In addition, employees and service providers may improperly use or disclose confidential information, which could result in litigation or serious financial harm, including limiting the Fund's business prospects or future marketing activities. Despite the Investment Advisor's due diligence efforts, misconduct and intentional misrepresentations may be undetected or not fully comprehended, thereby potentially undermining the Investment Advisor's due diligence efforts. As a result, no assurances can be given that the due diligence performed by the Investment Advisor will identify or prevent any such misconduct.

Portfolio Turnover Risk. The Fund's annual portfolio turnover rate may vary greatly from year to year, as well as within a given year. Portfolio turnover rate is not considered a limiting factor in the execution of investment decisions for the Fund. A higher portfolio turnover rate results in correspondingly greater brokerage commissions and other transactional expenses that are borne by the Fund. High portfolio turnover may result in an increased realization of net short-term capital gains by the Fund which, when distributed to common shareholders, will be taxable as ordinary income. Additionally, in a declining market, portfolio turnover may create realized capital losses.

Anti-Takeover Provisions Risk. The Fund's Agreement and Declaration of Trust and Bylaws include provisions that could limit the ability of other entities or persons to acquire control of the Fund or convert the Fund to open-end status or to change the composition of the Board. Such provisions could limit the ability of shareholders to sell their shares at a premium over prevailing market prices by discouraging a third party from seeking to obtain control of the Fund. See "Certain Provisions of the Agreement and Declaration of Trust and Bylaws" under Item 10.

Repurchase of Common Shares

The Fund is a closed-end management investment company and as such its shareholders will not have the right to cause the Fund to redeem their shares. Instead, the Fund's common shares will trade in the open market at a price that will be a function of several factors, including dividend levels (which are in turn affected by expenses), net asset value, call protection for portfolio securities, dividend stability, liquidity, relative demand for and supply of the common shares in the market, general market and economic conditions and other factors. Because shares of a closed-end investment company may frequently trade at prices lower than NAV, the Board may consider action that might be taken to reduce or eliminate any material discount from NAV in respect of common shares, which may include the repurchase of such shares in the open market or in private transactions, the making of a tender offer for such shares, or the conversion of the Fund to an open-end investment company. The Board may decide not to take any of these actions. In addition, there can be no assurance that share repurchases or tender offers, if undertaken, will reduce market discount.

II-82

Notwithstanding the foregoing, at any time when the Fund has preferred shares outstanding, the Fund may not purchase, redeem or otherwise acquire any of its common shares unless (1) all accrued preferred share dividends have been paid and (2) at the time of such purchase, redemption or acquisition, the NAV of the Fund's portfolio (determined after deducting the acquisition price of the common shares) is at least 200% of the liquidation value of any outstanding preferred shares (expected to equal the original purchase price per share plus any accrued and unpaid dividends thereon). Any service fees incurred in connection with any tender offer made by the Fund will be borne by the Fund and will not reduce the stated consideration to be paid to tendering shareholders.

Subject to its investment restrictions, the Fund may borrow to finance the repurchase of shares or to make a tender offer. Interest on any borrowings to finance share repurchase transactions or the accumulation of cash by the Fund in anticipation of share repurchases or tender offers will reduce the Fund's net income. Any share repurchase, tender offer or borrowing that might be approved by the Board would have to comply with the Exchange Act, the 1940 Act and the rules and regulations thereunder.

Although the decision to take action in response to a discount from NAV will be made by the Board at the time it considers such issue, it is the Board's present policy, which may be changed by the Board, not to authorize repurchases of common shares or a tender offer for such shares if: (i) such transactions, if consummated, would (a) result in the delisting of the common shares from the NYSE, or (b) impair the Fund's status as a RIC under the Code, (which would make the Fund a taxable entity, causing the Fund's income to be taxed at the corporate level in addition to the taxation of shareholders who receive dividends from the Fund) or as a registered closed-end investment company under the 1940 Act; (ii) the Fund would not be able to liquidate portfolio securities in an orderly manner and consistent with the Fund's investment objective and policies in order to repurchase shares; or (iii) there is, in the Board's judgment, any (a) material legal action or proceeding instituted or threatened challenging such transactions or otherwise materially adversely affecting the Fund, (b) general suspension of or limitation on prices for trading securities on the NYSE, (c) declaration of a banking moratorium by federal or state authorities or any suspension of payment by United States or New York banks, (d) material limitation affecting the Fund or the issuers of its portfolio securities by federal or state authorities on the extension of credit by lending institutions or on the exchange of foreign currency, (e) commencement of war, armed hostilities or other international or national calamity directly or indirectly involving the United States, or (f) other event or condition which would have a material adverse effect (including any adverse tax effect) on the Fund or its shareholders if shares were repurchased. The Board may in the future modify these conditions in light of experience.

The repurchase by the Fund of its shares at prices below NAV will result in an increase in the NAV of those shares that remain outstanding. However, there can be no assurance that share repurchases or tender offers at or below NAV will result in the Fund's shares trading at a price equal to their NAV. Nevertheless, the fact that the Fund's shares may be the subject of repurchases or tender offers from time to time, or that the Fund may be converted to an open-end investment company, may reduce any spread between market price and NAV that might otherwise exist.

In addition, a purchase by the Fund of its common shares will decrease the Fund's net assets which would likely have the effect of increasing the Fund's expense ratio. Any purchase by the Fund of its common shares at a time when preferred shares are outstanding will increase the leverage applicable to the outstanding common shares then remaining.

Before deciding whether to take any action if the common shares trade below NAV, the Board would likely consider all relevant factors, including the extent and duration of the discount, the liquidity of the Fund's portfolio, the impact of any action that might be taken on the Fund or its shareholders and market considerations. Based on these considerations, even if the Fund's shares should trade at a discount, the Board may determine that, in the interest of the Fund and its shareholders, no action should be taken.

Item 9. Management

Board of Trustees

The Board is responsible for the overall management of the Fund, including supervision of the duties performed by the Investment Advisor. There are eleven Trustees. A majority of the Trustees are Independent

II-83

Trustees. The name and business address of the Trustees and officers of the Fund and their principal occupations and other affiliations during the past five years are set forth under Item 18 in Part II of this Prospectus.

Investment Advisor

The Investment Advisor is responsible for the management of the Fund's portfolio and provides the necessary personnel, facilities, equipment and certain other services necessary to the operation of the Fund. The Investment Advisor, located at 100 Bellevue Parkway, Wilmington, Delaware 19809, is a wholly owned subsidiary of BlackRock, Inc. ("BlackRock").

BlackRock is one of the world's largest publicly-traded investment management firms and has over 20 years of experience managing closed-end products. As of September 30, 2014, BlackRock's assets under management were approximately $4.525 trillion.

BlackRock helps clients meet their goals and overcome challenges with a range of products that include separate accounts, mutual funds, iShares® (exchange-traded funds), and other pooled investment vehicles. BlackRock also offers risk management, advisory and enterprise investment system services to a broad base of institutional investors through BlackRock Solutions®. Headquartered in New York City, as of September 30, 2014, the firm has approximately 12,100 employees in more than 30 countries and a major presence in key global markets, including North and South America, Europe, Asia, Australia and the Middle East and Africa.

BlackRock is independent in ownership and governance, with no single majority shareholder and a majority of independent directors. PNC is BlackRock's largest shareholder and is an affiliate of BlackRock for 1940 Act purposes.

BlackRock's Investment Philosophy

The distinguishing feature of BlackRock's investment management style has been to seek to generate alpha (i.e. risk adjusted returns in excess of market returns) within a risk-controlled framework. Real-time analysis of a vast array of risk measures allows BlackRock to assess the potential impact of various sector and security strategies on total return. As a result, BlackRock seeks to add consistent value and limit performance volatility.

BlackRock's philosophy has not changed since the inception of the firm. The basis of successful investment performance is research and analysis of sectors and securities, not interest rate speculation. BlackRock believes that market-timing strategies are volatile and can produce inconsistent results.

Investment Management Agreement

The Investment Management Agreement between the Fund and the Investment Advisor was approved by the Fund's Board, including a majority of the Independent Trustees. Certain administrative services are also provided to the Fund by the Investment Advisor pursuant to the Investment Management Agreement between the Fund and the Investment Advisor. The Investment Advisor and its affiliates provide the Fund with administrative services, including, among others: (i) preparing disclosure documents, such as the prospectus and the statement of additional information (if applicable) in connection with public offerings and periodic shareholder reports; (ii) preparing communications with analysts to support secondary market trading of the Fund; (iii) assisting with daily accounting and pricing; (iv) preparing periodic filings with regulators and stock exchanges; (v) overseeing and coordinating the activities of other service providers; (vi) organizing Board meetings and preparing the materials for such Board meetings; (vii) providing legal and compliance support; (viii) furnishing analytical and other support to assist the Board in its consideration of strategic issues such as a merger or consolidation; and (ix) performing other administrative functions necessary for the operation of the Fund, such as tax reporting, fulfilling regulatory filing requirements and call center services.

The Investment Management Agreement is in effect for a one year term ending June 30, 2015 and will continue in effect for successive periods of 12 months thereafter, provided that each continuance is specifically approved at least annually by both (1) the vote of a majority of the Fund's Board or the vote of a majority of the outstanding voting securities of the Fund (as such term is defined in the 1940 Act) and (2) by the vote of a majority

II-84

of the Independent Trustees of the Fund, cast in person at a meeting called for the purpose of voting on such approval.

The Investment Management Agreement may be terminated at any time, without the payment of any penalty, by the Fund (upon the vote of a majority of the Fund's Board or a majority of the outstanding voting securities of the Fund) or by the Investment Advisor, upon 60 days' written notice by either party to the other which can be waived by the non-terminating party. The Investment Management Agreement will terminate automatically in the event of its assignment (as such term is defined in the 1940 Act and the rules thereunder).

The Investment Management Agreement provides that the Investment Advisor will not be liable for any error of judgment or mistake of law or for any loss suffered by the Fund in connection with the performance of the Investment Management Agreement, except a loss resulting from a breach of fiduciary duty with respect to the receipt of compensation for services or a loss resulting from willful misfeasance, bad faith or gross negligence on the Investment Advisor's part in the performance of its duties or from reckless disregard by the Investment Advisor of its duties under the Investment Management Agreement. The Investment Management Agreement also provides for indemnification by the Fund of the Investment Advisor, its directors, officers, employees, agents and control persons for liabilities incurred by them in connection with their services to the Fund, subject to certain limitations and conditions.

The Investment Advisor will devote such time and effort to the business of the Fund as is reasonably necessary to perform its duties to the Fund. However, the services of the Investment Advisor are not exclusive, and the Investment Advisor provides similar services to other investment companies and other clients and may engage in other activities.

Sub-Investment Advisory Agreement

BlackRock Financial Management, Inc. served as the sub-adviser for the Fund until July 1, 2014 when the sub-advisory agreement between the Investment Advisor and BlackRock Financial Management, Inc. expired.

Expenses

In addition to the fees paid to the Investment Advisor, the Fund pays all other costs and expenses of its operations, including compensation of its Trustees (other than those affiliated with the Investment Advisor), custodian, leveraging expenses, transfer and dividend disbursing agent expenses, legal fees, rating agency fees, listing fees and expenses, expenses of independent auditors, expenses of repurchasing shares, expenses of preparing, printing and distributing shareholder reports, notices, proxy statements and reports to governmental agencies and taxes, if any.

Other Service Providers

Pursuant to the Administration Agreement, State Street Bank and Trust Company provides the Fund with, among other things, customary fund accounting services, including computing the Fund's NAV and maintaining books, records and other documents relating to the Fund's financial and portfolio transactions, and customary fund administration services, including assisting the Fund with regulatory filings, tax compliance and other oversight activities.

The custodian of the assets of the Fund is State Street Bank and Trust Company, whose principal business address is 225 Franklin Street, Boston, Massachusetts 02110. The custodian is responsible for, among other things, receipt of and disbursement of funds from the Fund's accounts, establishment of segregated accounts as necessary, and transfer, exchange and delivery of Fund portfolio securities.

Computershare Trust Company, N.A., whose principal business address is 250 Royall Street, Canton, Massachusetts 02021, serves as the Fund's transfer agent, dividend disbursing agent and registrar with respect to the common shares.

II-85

, whose principal business address is , is the independent registered public accounting firm of the Fund and renders an opinion annually on the financial statements of the Fund.

Additional information regarding the Investment Advisor and the Fund's other service providers is set forth under Item 9 in Part I.

Item 10. Capital Stock, Long-Term Debt and Other Securities

Common Shares

Each common share has one vote and, when issued and paid for in accordance with the terms of this offering, will be fully paid and non-assessable, except that the Trustees shall have the power to cause shareholders to pay expenses of the Fund by setting off charges due from shareholders from declared but unpaid dividends or distributions owed the shareholders and/or by reducing the number of common shares owned by each respective shareholder. If and whenever preferred shares are outstanding, the holders of common shares will not be entitled to receive any distributions from the Fund unless all accrued dividends on preferred shares have been paid, unless asset coverage (as defined in the 1940 Act) with respect to preferred shares would be at least 200% after giving effect to the distributions and unless certain other requirements imposed by any rating agencies rating the preferred shares have been met. See "Preferred Shares," below. All common shares are equal as to dividends, assets and voting privileges and have no conversion, preemptive or other subscription rights.

The Fund intends to hold annual meetings of shareholders so long as the common shares are listed on a national securities exchange and such meetings are required as a condition to such listing. The Fund will send annual and semi-annual reports, including financial statements, to all holders of its shares.

Closed-end funds differ from open-end funds (which are generally referred to as mutual funds) in that closed-end funds generally list their shares for trading on a stock exchange and do not redeem their shares at the request of the shareholder. This means that if you wish to sell your shares of a closed-end fund you must trade them on the stock exchange like any other stock at the prevailing market price at that time. In a mutual fund, if the shareholder wishes to sell shares of the fund, the mutual fund will redeem or buy back the shares at "net asset value." Also, mutual funds generally offer new shares on a continuous basis to new investors and closed-end funds generally do not. The continuous inflows and outflows of assets in a mutual fund can make it difficult to manage the fund's investments. By comparison, closed-end funds are generally able to stay more fully invested in securities that are consistent with their investment objectives and also have greater flexibility to make certain types of investments and to use certain investment strategies, such as financial leverage and investments in illiquid securities.

Shares of closed-end investment companies like the Fund have during some periods traded at prices higher than NAV and during other periods have traded at prices lower than NAV. The Fund's common shares are designed primarily for long-term investors and you should not purchase the shares if you intend to sell them soon after purchase. Because of the possibility that the Fund's common shares might trade at a discount and the recognition that any such discount may not be in the interest of shareholders, the Board might consider from time to time engaging in open-market repurchases, tender offers for shares or other programs intended to reduce the discount. The Fund cannot guarantee or assure, however, that the Board will decide to engage in any of these actions. Nor is there any guarantee or assurance that such actions, if undertaken, would result in the shares trading at a price equal or close to the NAV. See "Repurchase of Common Shares" under Item 8, above. The Board might also consider converting the Fund to an open-end mutual fund, which would also require a vote of the shareholders of the Fund.

Preferred Shares

The Fund does not have any preferred shares outstanding at this time and it has no current intention to issue preferred shares. The Agreement and Declaration of Trust provides that the Board may authorize and issue preferred shares with rights as determined by the Board, by action of the Board without the approval of the holders of the common shares. Holders of common shares have no preemptive right to purchase any preferred shares that might be issued.

II-86

Under the 1940 Act, the Fund is not permitted to issue preferred shares unless immediately after such issuance the value of the Fund's total assets is at least 200% of the liquidation value of the outstanding shares of preferred stock (i.e., the liquidation value may not exceed 50% of the Fund's total assets). In addition, the Fund is not permitted to declare any cash dividend or other distribution on its common shares unless, at the time of such declaration, the value of the Fund's total assets is at least 200% of such liquidation value.

If preferred shares are issued, the Fund intends, to the extent possible, to purchase or redeem preferred shares from time to time to the extent necessary in order to maintain asset coverage of any preferred shares of at least 200%. In addition, as a condition to obtaining ratings on the preferred shares, the terms of any preferred shares issued are expected to include asset coverage maintenance provisions which will require the redemption of the preferred shares in the event of non-compliance by the Fund and may also prohibit dividends and other distributions on the common shares in such circumstances. In order to meet redemption requirements, the Fund may have to liquidate portfolio securities. Such liquidations and redemptions would cause the Fund to incur related transaction costs and could result in capital losses to the Fund. Prohibitions on dividends and other distributions on the common shares could impair the Fund's ability to qualify as a RIC under the Code.

If the Fund issues preferred shares, it may be subject to restrictions imposed by guidelines of one or more rating agencies that may issue ratings for preferred shares issued by the Fund. These guidelines may impose asset coverage or portfolio composition requirements that are more stringent than those imposed on the Fund by the 1940 Act. It is not anticipated that these covenants or guidelines would impede the Investment Advisor from managing the Fund's portfolio in accordance with the Fund's investment objectives and policies.

Any additional offerings of shares, including preferred, will require approval by the Board. Any additional offering of common shares will be subject to the requirements of the 1940 Act, which provides that shares may not be issued at a price below the then current NAV, exclusive of sales load, except in connection with an offering to existing holders of common shares or with the consent of a majority of the Fund's outstanding voting securities.

Although the terms of any preferred shares that the Fund might issue in the future, including dividend rate, liquidation preference and redemption provisions, will be determined by the Board, subject to applicable law and the Fund's Agreement and Declaration of Trust, it is likely that any such preferred shares issued would be structured to carry a relatively short-term dividend rate reflecting interest rates on short-term debt securities, by providing for the periodic redetermination of the dividend rate at relatively short intervals through a fixed spread or remarketing procedure, subject to a maximum rate which would increase over time in the event of an extended period of unsuccessful remarketing or other events, as applicable. The Fund also believes that it is likely that the liquidation preference, voting rights and redemption provisions of any such preferred shares would be similar to those stated below.

Liquidation Preference. In the event of any voluntary or involuntary liquidation, dissolution or winding up of the Fund, the holders of preferred shares will be entitled to receive a preferential liquidating distribution, which would be expected to equal the original purchase price per preferred share plus accrued and unpaid dividends, whether or not declared, before any distribution of assets is made to holders of common shares. After payment of the full amount of the liquidating distribution to which they are entitled, the holders of preferred shares would not be entitled to any further participation in any distribution of assets by the Fund.

Voting Rights. The 1940 Act requires that the holders of any preferred shares, voting separately as a single class, have the right to elect at least two Trustees at all times. The remaining Trustees will be elected by holders of common shares and preferred shares, voting together as a single class. In addition, subject to the prior rights, if any, of the holders of any other class of senior securities outstanding, the holders of any preferred shares have the right to elect a majority of the Trustees at any time two years' dividends on any preferred shares are unpaid. The 1940 Act also requires that, in addition to any approval by shareholders that might otherwise be required, the approval of the holders of a majority of any outstanding preferred shares, voting separately as a class, would be required to (1) adopt any plan of reorganization that would adversely affect the preferred shares, and (2) take any action requiring a vote of security holders under Section 13(a) of the 1940 Act, including, among other things, changes in the Fund's sub-classification as a closed-end investment company or changes in its fundamental investment restrictions. See "Certain Provisions of the Agreement and Declaration of Trust and Bylaws." As a result of these voting rights, the Fund's ability to take any such actions may be impeded to the extent that there are any preferred shares outstanding. The Board presently intends that, except as otherwise indicated in this Prospectus and except as otherwise required

II-87

by applicable law, holders of any preferred shares will have equal voting rights with holders of common shares (one vote per share, unless otherwise required by the 1940 Act) and will vote together with holders of common shares as a single class.

The affirmative vote of the holders of a majority of any outstanding preferred shares, voting as a separate class, would be required to amend, alter or repeal any of the preferences, rights or powers of holders of preferred shares so as to affect materially and adversely such preferences, rights or powers, or to increase or decrease the authorized number of preferred shares. The class vote of holders of preferred shares described above would in each case be in addition to any other vote required to authorize the action in question.

Redemption, Purchase and Sale of Preferred Shares by the Fund. The terms of any preferred shares are expected to provide that (1) they are redeemable by the Fund in whole or in part at the original purchase price per share plus accrued dividends per share, (2) the Fund may tender for or purchase preferred shares and (3) the Fund may subsequently resell any shares so tendered for or purchased. Any redemption or purchase of preferred shares by the Fund would reduce the leverage applicable to the common shares, while any resale of shares by the Fund would increase that leverage.

Liquidity Feature. Preferred shares may include a liquidity feature that allows holders of preferred shares to have their shares purchased by a liquidity provider in the event that sell orders have not been matched with purchase orders and successfully settled in a remarketing. The Fund will pay a fee to the provider of this liquidity feature, which would be borne by common shareholders of the Fund. The terms of such liquidity feature may require the Fund to redeem preferred shares still owned by the liquidity provider following a certain period of continuous, unsuccessful remarketing, which may adversely impact the Fund.

The discussion above describes the possible offering of preferred shares by the Fund. If the Board determines to proceed with such an offering, the terms of the preferred shares may be the same as, or different from, the terms described above, subject to applicable law and the Fund's Agreement and Declaration of Trust. The Board, without the approval of the holders of common shares, may authorize an offering of preferred shares or may determine not to authorize such an offering, and may fix the terms of the preferred shares to be offered.

Other Shares

In addition, the Board (subject to applicable law and the Fund's Agreement and Declaration of Trust) may authorize an offering, without the approval of the holders of common shares and, depending on their terms, any preferred shares outstanding at that time, of other classes of shares, or other classes or series of shares, as they determine to be necessary, desirable or appropriate, having such terms, rights, preferences, privileges, limitations and restrictions as the Board sees fit. The Fund currently does not expect to issue any other classes of shares, or series of shares, except for the common shares.

Credit Facility

The Fund is also authorized to borrow through a credit facility. Pursuant to the requirements of the 1940 Act, the Fund would not be able to declare dividends or make other distributions on common shares or purchase any such common shares if, at the time of the declaration, distribution or purchase, asset coverage with respect to outstanding borrowings is less than 300%. If the Fund enters into a credit facility, the Fund may be required to prepay outstanding amounts or incur a penalty rate of interest upon the occurrence of certain events of default. The Fund would also likely have to indemnify the lenders under the credit facility against liabilities they may incur in connection therewith. In addition, the Fund expects that any credit facility would contain covenants that, among other things, likely would limit the Fund's ability to pay distributions in certain circumstances, incur additional debt, change certain of its investment policies and engage in certain transactions, including mergers and consolidations, and require asset coverage ratios in addition to those required by the 1940 Act. The Fund may be required to pledge its assets and to maintain a portion of its assets in cash or high-grade securities as a reserve against interest or principal payments and expenses. The Fund expects that any credit facility would have customary covenant, negative covenant and default provisions. There can be no assurance that the Fund will enter into an agreement for a credit facility, or one on terms and conditions representative of the foregoing, or that additional material terms will not apply. In addition, if entered into, a credit facility may in the future be replaced or refinanced by one or more credit facilities having substantially different terms or by the issuance of preferred shares.

See "Risk Factors—Leverage Risk" under Item 8, above.

II-88

Distributions

The Fund's net investment income consists of all interest income accrued on portfolio assets less all expenses of the Fund. The Fund pays common shareholders at least annually all or substantially all of its investment company taxable income. The Fund intends to pay any capital gains distributions at least annually. The 1940 Act generally limits the Fund to one capital gain distribution per year, subject to certain exceptions.

The tax treatment and characterization of the Fund's distributions may vary significantly from time to time because of the varied nature of the Fund's investments. The final tax characterization of distributions is determined after the fiscal year and is reported in the Fund's annual report to shareholders. Distributions will be characterized as ordinary income, capital gains and/or return of capital. To the extent that distributions exceed the Fund's current and accumulated earnings and profits, the excess may be treated as a non-taxable return of capital to the extent of the shareholder's basis in its shares (reducing that basis accordingly), and as capital gain thereafter. Distributions that exceed the Fund's taxable net investment income or net realized capital gains ("taxable income") but do not exceed the Fund's current and accumulated earnings and profits may be classified as ordinary income that is taxable to shareholders.

As described above, the portion of distributions that exceeds the Fund's current and accumulated earnings and profits, which are calculated under tax principles, will constitute a non-taxable return of capital. Although capital loss carry forwards ("CLCFs") from prior years can offset realized net capital gains, CLCFs will offset current earnings and profits, only if they were generated in the Fund's 2012 taxable year or thereafter. If distributions in any tax year are less than the Fund's current earnings and profits but are in excess of net investment income and net realized capital gains (which would occur, for example, if the Fund utilizes pre-2012 CLCFs to offset capital gains in that tax year), such excess is not treated as a non-taxable return of capital but rather may be taxable to shareholders at ordinary income rates even though it may economically represent a return of capital. Under certain circumstances, such taxable excess distributions could be significant.

Various factors will affect the level of the Fund's net investment income, such as its asset mix, its level of retained earnings, its use of hedging, the amount of leverage utilized by the Fund and the effects thereof and the movement of interest rates for debt securities. To permit the Fund to maintain more stable monthly distributions and to the extent consistent with the distribution requirements imposed on regulated investment companies by the Code, the Fund may from time to time distribute less than the entire amount earned in a particular period. The income would be available to supplement future distributions. As a result, the distributions paid by the Fund for any particular month may be more or less than the amount actually earned by the Fund during that month. Undistributed income will add to the Fund's NAV and, correspondingly, distributions from undistributed income will deduct from the Fund's NAV.

Under normal market conditions, the Investment Advisor will seek to manage the Fund in a manner such that the Fund's distributions are reflective of the Fund's current and projected earnings levels. The distribution level of the Fund is subject to change based upon a number of factors, including the current and projected level of the Fund's earnings, and may fluctuate over time.

Shareholders will automatically have all dividends and distributions reinvested in common shares of the Fund issued by the Fund or purchased in the open market in accordance with the Fund's dividend reinvestment plan unless an election is made to receive cash. See "Dividend Reinvestment Plan," below.

Dividend Reinvestment Plan

Unless the registered owner of common shares elects to receive cash by contacting Computershare Trust Company, N.A. (the "Reinvestment Plan Agent"), all dividends or other distributions (together, a "dividend") declared for your common shares of the Fund will be automatically reinvested by the Reinvestment Plan Agent, as agent for shareholders in administering the Fund's dividend reinvestment plan (the "Reinvestment Plan"), in additional common shares of the Fund. Shareholders who elect not to participate in the Reinvestment Plan will receive all dividends in cash paid by check mailed directly to the shareholder of record (or, if the common shares are held in street or other nominee name, then to such nominee) by Computershare Trust Company, N.A., as dividend

II-89

disbursing agent. You may elect not to participate in the Reinvestment Plan and to receive all dividends in cash by contacting Computershare Trust Company, N.A., as Reinvestment Plan Agent, at the address set forth below. Participation in the Reinvestment Plan is completely voluntary and may be terminated or resumed at any time without penalty by written notice if received and processed by the Reinvestment Plan Agent prior to the dividend record date. Additionally, the Reinvestment Plan Agent seeks to process notices received after the record date but prior to the payable date and such notices often will become effective by the payable date. Where late notices are not processed by the applicable payable date, such termination or resumption will be effective with respect to any subsequently declared dividend.

Some brokers may automatically elect to receive cash on your behalf and may re-invest that cash in additional common shares of the Fund for you. If you wish for all dividends declared on your common shares of the Fund to be automatically reinvested pursuant to the Reinvestment Plan, please contact your broker.

The Reinvestment Plan Agent will open an account for each common shareholder under the Reinvestment Plan in the same name in which such common shareholder's common shares are registered. Whenever the Fund declares a dividend payable in cash, non-participants in the Reinvestment Plan will receive cash and participants in the Reinvestment Plan will receive the equivalent in common shares. The common shares will be acquired by the Reinvestment Plan Agent for the participants' accounts, depending upon the circumstances described below, either (i) through receipt of additional unissued but authorized common shares from the Fund ("newly issued common shares") or (ii) by purchase of outstanding common shares on the open market ("open-market purchases") or on the Fund's primary exchange. If, on the dividend payment date, the NAV per share is equal to or less than the market price per share plus estimated brokerage commissions (such condition often referred to as a "market premium"), the Reinvestment Plan Agent will invest the dividend amount in newly issued common shares on behalf of the participants. The number of newly issued common shares to be credited to each participant's account will be determined by dividing the dollar amount of the dividend by the NAV on the dividend payment date. However, if the NAV is less than 95% of the market price on the dividend payment date, the dollar amount of the dividend will be divided by 95% of the market price on the dividend payment date. If, on the dividend payment date, the NAV is greater than the market price per share plus estimated brokerage commissions (such condition often referred to as a "market discount"), the Reinvestment Plan Agent will invest the dividend amount in common shares acquired on behalf of the participants in open-market purchases. In the event of a market discount on the dividend payment date, the Reinvestment Plan Agent will have until the last business day before the next date on which the common shares trade on an "ex-dividend" basis or 30 days after the dividend payment date, whichever is sooner, to invest the dividend amount in common shares acquired in open-market purchases. If, before the Reinvestment Plan Agent has completed its open-market purchases, the market price per common share exceeds the NAV per common share, the average per common share purchase price paid by the Reinvestment Plan Agent may exceed the NAV of the common shares, resulting in the acquisition of fewer common shares than if the dividend had been paid in newly issued common shares on the dividend payment date. Because of the foregoing difficulty with respect to open-market purchases, the Reinvestment Plan provides that if the Reinvestment Plan Agent is unable to invest the full dividend amount in open-market purchases, or if the market discount shifts to a market premium during the purchase period, the Reinvestment Plan Agent may cease making open-market purchases and may invest any uninvested portion in newly issued shares. Investments in newly issued shares made in this manner would be made pursuant to the same process described above and the date of issue for such newly issued shares will substitute for the dividend payment date.

The Reinvestment Plan Agent maintains all shareholders' accounts in the Reinvestment Plan and furnishes written confirmation of all transactions in the accounts, including information needed by shareholders for tax records. Common shares in the account of each Reinvestment Plan participant will be held by the Reinvestment Plan Agent on behalf of the Reinvestment Plan participant, and each shareholder proxy will include those shares purchased or received pursuant to the Reinvestment Plan. The Reinvestment Plan Agent will forward all proxy solicitation materials to participants and vote proxies for shares held under the Reinvestment Plan in accordance with the instructions of the participants.

In the case of shareholders such as banks, brokers or nominees, which hold shares for others who are the beneficial owners, the Reinvestment Plan Agent will administer the Reinvestment Plan on the basis of the number of common shares certified from time to time by the record shareholder's name and held for the account of beneficial owners who participate in the Reinvestment Plan.

II-90

The Reinvestment Plan Agent's fees for the handling of the reinvestment of dividends will be paid by the Fund. However, each participant will pay a $0.02 per share fee incurred in connection with open-market purchases, which will be deducted from the value of the dividend. The automatic reinvestment of dividends will not relieve participants of any U.S. federal, state or local income tax that may be payable (or required to be withheld) on such dividends. See "Tax Matters."

Participants that request a sale of shares through the Reinvestment Plan Agent are subject to a $2.50 sales fee and a $0.15 per share fee. Per share fees include any applicable brokerage commissions the Reinvestment Plan Agent is required to pay.

The Fund reserves the right to amend or terminate the Reinvestment Plan. There is no direct service charge to participants with regard to purchases in the Reinvestment Plan; however, the Fund reserves the right to amend the Reinvestment Plan to include a service charge payable by the participants. Notice of amendments to the Reinvestment Plan will be sent to participants.

All correspondence concerning the Reinvestment Plan should be directed to the Reinvestment Plan Agent, through the internet at www.computershare.com/blackrock, by calling 1-800-699-1236 or in writing to Computershare Trust Company, N.A., P.O. Box 30170, College Station, TX 77842-3170.

Certain Provisions of the Agreement and Declaration of Trust and Bylaws

The Agreement and Declaration of Trust includes provisions that could have the effect of limiting the ability of other entities or persons to acquire control of the Fund or to change the composition of the Board. This could have the effect of depriving shareholders of an opportunity to sell their shares at a premium over prevailing market prices by discouraging a third party from seeking to obtain control over the Fund. Such attempts could have the effect of increasing the expenses of the Fund and disrupting the normal operation of the Fund. The Board is divided into three classes, with the terms of one class expiring at each annual meeting of shareholders. At each annual meeting, one class of Trustees is elected to a three-year term. This provision could delay for up to two years the replacement of a majority of the Board. A Trustee may be removed from office for cause only, and only by the action of a majority of the remaining Trustees followed by a vote of the holders of at least 75% of the shares then entitled to vote for the election of the respective Trustee.

In addition, the Fund's Agreement and Declaration of Trust requires the favorable vote of a majority of the Board followed by the favorable vote of the holders of at least 75% of the outstanding shares of each affected class or series of the Fund, voting separately as a class or series, to approve, adopt or authorize certain transactions with 5% or greater holders of a class or series of shares and their associates, unless the transaction has been approved by at least 80% of the Trustees, in which case "a majority of the outstanding voting securities" (as defined in the 1940 Act) of the Fund shall be required. These voting requirements are in addition to any regulatory relief required from the SEC with respect to such transaction. For purposes of these provisions, a 5% or greater holder of a class or series of shares (a "Principal Shareholder") refers to any person who, whether directly or indirectly and whether alone or together with its affiliates and associates, beneficially owns 5% or more of the outstanding shares of any class or series of shares of beneficial interest of the Fund.

The 5% holder transactions subject to these special approval requirements are:

the merger or consolidation of the Fund or any subsidiary of the Fund with or into any Principal Shareholder;

the issuance of any securities of the Fund to any Principal Shareholder for cash (other than pursuant to any automatic dividend reinvestment plan);

the sale, lease or exchange of all or any substantial part of the assets of the Fund to any Principal Shareholder, except assets having an aggregate fair market value of less than $1,000,000, aggregating for the purpose of such computation all assets sold, leased or exchanged in any series of similar transactions within a twelve-month period; or

II-91

the sale, lease or exchange to the Fund or any subsidiary of the Fund, in exchange for securities of the Fund, of any assets of any Principal Shareholder, except assets having an aggregate fair market value of less than $1,000,000, aggregating for purposes of such computation all assets sold, leased or exchanged in any series of similar transactions within a twelve-month period.

To convert the Fund to an open-end investment company, the Fund's Agreement and Declaration of Trust requires the favorable vote of a majority of the Board followed by the favorable vote of the holders of at least 75% of the outstanding shares of each affected class or series of shares of the Fund, voting separately as a class or series, unless such amendment has been approved by at least 80% of the Trustees, in which case "a majority of the outstanding voting securities" (as defined in the 1940 Act) of the Fund shall be required. The foregoing vote would satisfy a separate requirement in the 1940 Act that any conversion of the Fund to an open-end investment company be approved by the shareholders. If approved in the foregoing manner, conversion of the Fund to an open-end investment company might not occur until 90 days after the shareholders' meeting at which such conversion was approved and would also require at least 10 days' prior notice to all shareholders. Conversion of the Fund to an open-end investment company would require the redemption of any outstanding preferred shares, which could eliminate or alter the leveraged capital structure of the Fund with respect to the common shares. Following any such conversion, it is also possible that certain of the Fund's investment policies and strategies would have to be modified to assure sufficient portfolio liquidity. In the event of conversion, the common shares would cease to be listed on the NYSE or other national securities exchanges or market systems. Shareholders of an open-end investment company may require the company to redeem their shares at any time, except in certain circumstances as authorized by or under the 1940 Act, at their NAV, less such redemption charge, if any, as might be in effect at the time of a redemption. The Fund expects to pay all such redemption requests in cash, but reserves the right to pay redemption requests in a combination of cash or securities. If such partial payment in securities were made, investors may incur brokerage costs in converting such securities to cash. If the Fund were converted to an open-end fund, it is likely that new shares would be sold at NAV plus a sales load. The Board believes, however, that the closed-end structure is desirable in light of the Fund's investment objective and policies. Therefore, you should assume that it is not likely that the Board would vote to convert the Fund to an open-end fund.

To liquidate the Fund, the Fund's Agreement and Declaration of Trust, requires the favorable vote of a majority of the Board followed by the favorable vote of the holders of at least 75% of the outstanding shares of each affected class or series of the Fund, voting separately as a class or series, unless such amendment has been approved by at least 80% of Trustees, in which case "a majority of the outstanding voting securities" (as defined in the 1940 Act) of the Fund shall be required.

For the purposes of calculating "a majority of the outstanding voting securities" under the Fund's Agreement and Declaration of Trust, each class and series of the Fund shall vote together as a single class, except to the extent required by the 1940 Act or the Fund's Agreement and Declaration of Trust with respect to any class or series of shares. If a separate vote is required, the applicable proportion of shares of the class or series, voting as a separate class or series, also will be required.

The Board has determined that provisions with respect to the Board and the shareholder voting requirements described above, which voting requirements are greater than the minimum requirements under Delaware law or the 1940 Act, are in the best interest of shareholders generally. Reference should be made to the Agreement and Declaration of Trust on file with the SEC for the full text of these provisions.

The Fund's Bylaws generally require that advance notice be given to the Fund in the event a shareholder desires to transact any business, including business from the floor, at an annual meeting of shareholders, including the nomination of Trustees. Notice of any such business or nomination must be in writing, comply with the requirements of the Bylaws and be received by the Fund not less than 120 calendar days nor more than 150 calendar days prior to the anniversary date of the prior year's annual meeting. In the event the Fund moves the date of its annual meeting by more than 25 days from the anniversary of its immediately preceding annual meeting, shareholders who wish to submit a proposal or nomination for consideration at the annual meeting in accordance with the advance notice provisions of the Bylaws of the Fund must deliver such proposal or nomination not later than the close of business on the tenth day following the day on which such notice of the date of the meeting was mailed or such public disclosure of the meeting date was made, whichever comes first. Any notice by a shareholder

II-92

must be accompanied by certain information as provided in the Bylaws. Reference should be made to the Bylaws on file with the SEC for the full text of these provisions.

Net Asset Value

The NAV of the Fund's common shares will be computed based upon the value of the Fund's portfolio securities and other assets. NAV per common share will be determined as of the close of the regular trading session on the NYSE on each business day on which the NYSE is open for trading. The Fund calculates NAV per common share by subtracting the Fund's liabilities (including accrued expenses, dividends payable and any borrowings of the Fund), and the liquidation value of any outstanding Fund preferred shares from the Fund's total assets (the value of the securities the Fund holds plus cash or other assets, including interest accrued but not yet received) and dividing the result by the total number of common shares of the Fund outstanding.

Valuation of securities held by the Fund is as follows:

Equity Investments. Equity securities traded on a recognized securities exchange (e.g., NYSE), separate trading boards of a securities exchange or through a market system that provides contemporaneous transaction pricing information (an "Exchange") are valued via independent pricing services generally at the Exchange closing price or if an Exchange closing price is not available, the last traded price on that Exchange prior to the time as of which the assets or liabilities are valued, however, under certain circumstances other means of determining current market value may be used. If an equity security is traded on more than one Exchange, the current market value of the security where it is primarily traded generally will be used. In the event that there are no sales involving an equity security held by the Fund on a day on which the Fund values such security, the last bid (long positions) or ask (short positions) price, if available, will be used as the value of such security. If the Fund holds both long and short positions in the same security, the last bid price will be applied to securities held long and the last ask price will be applied to securities sold short. If no bid or ask price is available on a day on which the Fund values such security, the prior day's price will be used, unless BlackRock determines that such prior day's price no longer reflects the fair value of the security, in which case such asset would be treated as a fair value asset.

Fixed Income Investments. Fixed income securities for which market quotations are readily available are generally valued using such securities' most recent bid prices provided directly from one or more broker-dealers, market makers, or independent third-party pricing services which may use matrix pricing and valuation models to derive values, each in accordance with valuation procedures approved by the Board. The amortized cost method of valuation may be used with respect to debt obligations with sixty days or less remaining to maturity unless the Investment Advisor determines such method does not represent fair value. Loan participation notes are generally valued at the mean of the last available bid prices from one or more brokers or dealers as obtained from independent third-party pricing services. Certain fixed income investments including asset-backed and mortgage-related securities may be valued based on valuation models that consider the estimated cash flows of each tranche of the entity, establish a benchmark yield and develop an estimated tranche specific spread to the benchmark yield based on the unique attributes of the tranche. Fixed income securities for which market quotations are not readily available may be valued by third-party pricing services that make a valuation determination by securing transaction data (e.g., recent representative bids), credit quality information, perceived market movements, news, and other relevant information and by other methods, which may include consideration of: yields or prices of securities of comparable quality, coupon, maturity and type; indications as to values from dealers; and general market conditions.

Options, Futures, Swaps and Other Derivatives. Exchange-traded equity options for which market quotations are readily available are valued at the mean of the last bid and ask prices as quoted on the Exchange or the board of trade on which such options are traded. In the event that there is no mean price available for an exchange traded equity option held by the Fund on a day on which the Fund values such option, the last bid (long positions) or ask (short positions) price, if available, will be used as the value of such option. If no bid or ask price is available on a day on which the Fund values such option, the prior day's price will be used, unless BlackRock determines that such prior day's price no longer reflects the fair value of the option in which case such option will be treated as a fair value asset. OTC derivatives may be valued using a mathematical model which may incorporate a number of market data factors. Financial futures contracts and options thereon, which are traded on exchanges, are valued at their last sale price or settle price as of the close of such exchanges. Swap agreements and other derivatives are generally valued daily based upon quotations from market makers or by a pricing service in accordance with the valuation procedures approved by the Board.

II-93

Underlying Funds. Shares of underlying open-end funds are valued at NAV. Shares of underlying exchange-traded closed-end funds or other exchange-traded funds will be valued at their most recent closing price.

General Valuation Information. In determining the market value of portfolio investments, the Fund may employ independent third party pricing services, which may use, without limitation, a matrix or formula method that takes into consideration market indexes, matrices, yield curves and other specific adjustments. This may result in the securities being valued at a price different from the price that would have been determined had the matrix or formula method not been used. All cash, receivables and current payables are carried on the Fund's books at their face value.

Prices obtained from independent third party pricing services, broker-dealers or market makers to value the Fund's securities and other assets and liabilities are based on information available at the time the Fund values its assets and liabilities. In the event that a pricing service quotation is revised or updated subsequent to the day on which the Fund valued such security, the revised pricing service quotation generally will be applied prospectively. Such determination shall be made considering pertinent facts and circumstances surrounding such revision.

In the event that application of the methods of valuation discussed above result in a price for a security which is deemed not to be representative of the fair market value of such security, the security will be valued by, under the direction of or in accordance with a method specified by the Board as reflecting fair value. All other assets and liabilities (including securities for which market quotations are not readily available) held by the Fund (including restricted securities) are valued at fair value as determined in good faith by the Board or by BlackRock (its delegate). Any assets and liabilities which are denominated in a foreign currency are translated into U.S. dollars at the prevailing rates of exchange.

Certain of the securities acquired by the Fund may be traded on foreign exchanges or over-the-counter markets on days on which the Fund's NAV is not calculated. In such cases, the NAV of the Fund's shares may be significantly affected on days when investors can neither purchase nor redeem shares of the Fund.

Fair Value. When market quotations are not readily available or are believed by BlackRock to be unreliable, the Fund's investments are valued at fair value ("Fair Value Assets"). Fair Value Assets are valued by BlackRock in accordance with procedures approved by the Board. BlackRock may conclude that a market quotation is not readily available or is unreliable if a security or other asset or liability does not have a price source due to its complete lack of trading, if BlackRock believes a market quotation from a broker-dealer or other source is unreliable (e.g., where it varies significantly from a recent trade, or no longer reflects the fair value of the security or other asset or liability subsequent to the most recent market quotation), where the security or other asset or liability is only thinly traded or due to the occurrence of a significant event subsequent to the most recent market quotation. For this purpose, a "significant event" is deemed to occur if BlackRock determines, in its business judgment prior to or at the time of pricing the Fund's assets or liabilities, that it is likely that the event will cause a material change to the last exchange closing price or closing market price of one or more assets or liabilities held by the Fund. On any date the NYSE is open and the primary exchange on which a foreign asset or liability is traded is closed, such asset or liability will be valued using the prior day's price, provided that BlackRock is not aware of any significant event or other information that would cause such price to no longer reflect the fair value of the asset or liability, in which case such asset or liability would be treated as a Fair Value Asset. For certain foreign securities, a third-party vendor supplies evaluated, systematic fair value pricing based upon the movement of a proprietary multi-factor model after the relevant foreign markets have closed. This systematic fair value pricing methodology is designed to correlate the prices of foreign securities following the close of the local markets to the price that might have prevailed as of the Fund's pricing time.

BlackRock, with input from the BlackRock Portfolio Management Group, will submit its recommendations regarding the valuation and/or valuation methodologies for Fair Value Assets to BlackRock's Valuation Committee. The Valuation Committee may accept, modify or reject any recommendations. In addition, the Fund's accounting agent periodically endeavors to confirm the prices it receives from all third party pricing services, index providers and broker-dealers, and, with the assistance of BlackRock, to regularly evaluate the values assigned to the securities and other assets and liabilities held by the Fund. The pricing of all Fair Value Assets is subsequently reported to and ratified by the Board or a Committee thereof.

When determining the price for a Fair Value Asset, the BlackRock Valuation Committee (or the Pricing Group) shall seek to determine the price that the Fund might reasonably expect to receive from the current sale of

II-94

that asset or liability in an arm's-length transaction. The price generally may not be determined based on what the Fund might reasonably expect to receive for selling an asset or liability at a later time or if it holds the asset or liability to maturity. Fair value determinations shall be based upon all available factors that the Valuation Committee (or Pricing Group) deems relevant at the time of the determination, and may be based on analytical values determined by BlackRock using proprietary or third party valuation models.

Fair value represents a good faith approximation of the value of an asset or liability. The fair value of one or more assets or liabilities may not, in retrospect, be the price at which those assets or liabilities could have been sold during the period in which the particular fair values were used in determining the Fund's NAV. As a result, the Fund's sale or redemption of its shares at NAV, at a time when a holding or holdings are valued at fair value, may have the effect of diluting or increasing the economic interest of existing shareholders.

The Fund's annual audited financial statements, which are prepared in accordance with accounting principles generally accepted in the United States of America ("US GAAP"), follow the requirements for valuation set forth in Financial Accounting Standards Board Accounting Standards Codification Topic 820, "Fair Value Measurements and Disclosures" ("ASC 820"), which defines and establishes a framework for measuring fair value under US GAAP and expands financial statement disclosure requirements relating to fair value measurements.

Generally, ASC 820 and other accounting rules applicable to investment companies and various assets in which they invest are evolving. Such changes may adversely affect the Fund. For example, the evolution of rules governing the determination of the fair market value of assets or liabilities to the extent such rules become more stringent would tend to increase the cost and/or reduce the availability of third-party determinations of fair market value. This may in turn increase the costs associated with selling assets or affect their liquidity due to the Fund's inability to obtain a third-party determination of fair market value.

Tax Matters

The following is a description of certain U.S. federal income tax consequences to a shareholder of acquiring, holding and disposing of common shares of the Fund. This discussion is based upon current provisions of the Code, the regulations promulgated thereunder and judicial and administrative authorities, all of which are subject to change or differing interpretations by the courts or the Internal Revenue Service (the "IRS"), possibly with retroactive effect. No attempt is made to present a detailed explanation of all U.S. federal income tax concerns affecting the Fund and its shareholders (including shareholders subject to special provisions of the Code), and the discussions set forth here do not constitute tax advice. This discussion assumes that investors hold common shares of the Fund as capital assets (generally, for investment). The Fund has not sought and will not seek any ruling from the IRS regarding any matters discussed herein. No assurance can be given that the IRS would not assert, or that a court would not sustain, a position contrary to those set forth below. This summary does not discuss any aspects of foreign, state or local tax. Prospective investors must consult their own tax advisers as to the U.S. federal income tax consequences (including the alternative minimum tax consequences) of acquiring, holding and disposing of the Fund's shares, as well as the effects of state, local and non-U.S. tax laws.

Taxation of the Fund. The Fund has elected to be treated as a regulated investment company under Subchapter M of the Code. In order to qualify as a RIC, the Fund must, among other things, satisfy certain requirements relating to the sources of its income, diversification of its assets, and distribution of its income to its shareholders. First, the Fund must derive at least 90% of its annual gross income from dividends, interest, payments with respect to securities loans, gains from the sale or other disposition of stock or securities or foreign currencies, or other income (including but not limited to gains from options, futures and forward contracts) derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in "qualified publicly traded partnerships" (as defined in the Code) (the "90% gross income test"). Second, the Fund must diversify its holdings so that, at the close of each quarter of its taxable year, (i) at least 50% of the value of its total assets consists of cash, cash items, U.S. Government securities, securities of other RICs and other securities, limited in respect of any one issuer to an amount not greater in value than 5% of the value of the Fund's total assets and to not more than 10% of the outstanding voting securities of such issuer, and (ii) not more than 25% of the value of the total assets is invested in the securities (other than U.S. Government securities and securities of other RICs) of any one issuer, any two or more issuers controlled by the Fund and engaged in the same, similar or related trades or businesses, or any one or more "qualified publicly traded partnerships."

II-95

As long as the Fund qualifies as a RIC, the Fund will generally not be subject to corporate-level U.S. federal income tax on income and gains that it distributes each taxable year to its shareholders, provided that in such taxable year it distributes at least 90% of the sum of (i) its net tax-exempt interest income and (ii) its "investment company taxable income" (which includes, among other items, dividends, taxable interest, taxable original issue discount and market discount income, income from securities lending, net short-term capital gain in excess of net long-term capital loss, and any other taxable income other than "net capital gain" (as defined below) and is reduced by deductible expenses) determined without regard to the deduction for dividends paid. The Fund may retain for investment its net capital gain (which consists of the excess of its net long-term capital gain over its net short-term capital loss). However, if the Fund retains any net capital gain or any investment company taxable income, it will be subject to tax at regular corporate rates on the amount retained.

The Code imposes a 4% nondeductible excise tax on the Fund to the extent the Fund does not distribute by the end of any calendar year at least the sum of (i) 98% of its ordinary income (not taking into account any capital gain or loss) for the calendar year and (ii) 98.2% of its capital gain in excess of its capital loss (adjusted for certain ordinary losses) for a one-year period generally ending on October 31 of the calendar year (unless an election is made to use the Fund's fiscal year). In addition, the minimum amounts that must be distributed in any year to avoid the excise tax will be increased or decreased to reflect any under-distribution or over-distribution, as the case may be, from the previous year. For purposes of the excise tax, the Fund will be deemed to have distributed any income on which it paid U.S. federal income tax. While the Fund intends to distribute any income and capital gain in the manner necessary to minimize imposition of the 4% nondeductible excise tax, there can be no assurance that sufficient amounts of the Fund's taxable income and capital gain will be distributed to entirely avoid the imposition of the excise tax. In that event, the Fund will be liable for the excise tax only on the amount by which it does not meet the foregoing distribution requirement.

If in any taxable year the Fund should fail to qualify under Subchapter M of the Code for tax treatment as a RIC, the Fund would incur a regular corporate U.S. federal income tax upon all of its taxable income for that year, and all distributions to its shareholders (including distributions of net capital gain) would be taxable to shareholders as ordinary dividend income for U.S. federal income tax purposes to the extent of the Fund's earnings and profits. Provided that certain holding period and other requirements were met, such dividends would be eligible (i) to be treated as qualified dividend income in the case of shareholders taxed as individuals and (ii) for the dividends received deduction in the case of corporate shareholders. In addition, to qualify again to be taxed as a RIC in a subsequent year, the Fund would be required to distribute to shareholders its earnings and profits attributable to non-RIC years. In addition, if the Fund failed to qualify as a RIC for a period greater than two taxable years, then, in order to qualify as a RIC in a subsequent year, the Fund would be required to elect to recognize and pay tax on any net built-in gain (the excess of aggregate gain, including items of income, over aggregate loss that would have been realized if the Fund had been liquidated) or, alternatively, be subject to taxation on such built-in gain recognized for a period of ten years.

The remainder of this discussion assumes that the Fund qualifies for taxation as a RIC.

The Fund's Investments. Certain of the Fund's investment practices are subject to special and complex U.S. federal income tax provisions (including mark-to-market, constructive sale, straddle, wash sale, short sale and other rules) that may, among other things, (i) disallow, suspend or otherwise limit the allowance of certain losses or deductions, (ii) convert lower taxed long-term capital gains or qualified dividend income into higher taxed short-term capital gains or ordinary income, (iii) convert ordinary loss or a deduction into capital loss (the deductibility of which is more limited), (iv) cause the Fund to recognize income or gain without a corresponding receipt of cash, (v) adversely affect the time as to when a purchase or sale of stock or securities is deemed to occur, (vi) adversely alter the characterization of certain complex financial transactions and (vii) produce income that will not be "qualified" income for purposes of the 90% annual gross income requirement described above. These U.S. federal income tax provisions could therefore affect the amount, timing and character of distributions to common shareholders. The Fund intends to monitor its transactions and may make certain tax elections and may be required to dispose of securities to mitigate the effect of these provisions and prevent disqualification of the Fund as a RIC. Additionally, the Fund may be required to limit its activities in derivative instruments in order to enable it to maintain its RIC status.

The Fund may invest a portion of its net assets in below investment grade securities. Investments in these types of securities may present special tax issues for the Fund. U.S. federal income tax rules are not entirely clear

II-96

about issues such as when the Fund may cease to accrue interest, original issue discount or market discount, when and to what extent deductions may be taken for bad debts or worthless securities, how payments received on obligations in default should be allocated between principal and income and whether modifications or exchanges of debt obligations in a bankruptcy or workout context are taxable. These and other issues could affect the Fund's ability to distribute sufficient income to preserve its status as a RIC or to avoid the imposition of U.S. federal income or excise tax.

Certain debt securities acquired by the Fund may be treated as debt securities that were originally issued at a discount. Generally, the amount of the original issue discount is treated as interest income and is included in taxable income (and required to be distributed by the Fund in order to qualify as a RIC and avoid U.S. federal income tax or the 4% excise tax on undistributed income) over the term of the security, even though payment of that amount is not received until a later time, usually when the debt security matures.

If the Fund purchases a debt security on a secondary market at a price lower than its adjusted issue price, the excess of the adjusted issue price over the purchase price is "market discount." Unless the Fund makes an election to accrue market discount on a current basis, generally, any gain realized on the disposition of, and any partial payment of principal on, a debt security having market discount is treated as ordinary income to the extent the gain, or principal payment, does not exceed the "accrued market discount" on the debt security. Market discount generally accrues in equal daily installments. If the Fund ultimately collects less on the debt instrument than its purchase price plus the market discount previously included in income, the Fund may not be able to benefit from any offsetting loss deductions.

The Fund may invest in preferred securities or other securities the U.S. federal income tax treatment of which may not be clear or may be subject to recharacterization by the IRS. To the extent the tax treatment of such securities or the income from such securities differs from the tax treatment expected by the Fund, it could affect the timing or character of income recognized by the Fund, potentially requiring the Fund to purchase or sell securities, or otherwise change its portfolio, in order to comply with the tax rules applicable to RICs under the Code.

Gain or loss on the sale of securities by the Fund will generally be long-term capital gain or loss if the securities have been held by the Fund for more than one year. Gain or loss on the sale of securities held for one year or less will be short-term capital gain or loss.

Because the Fund may invest in foreign securities, its income from such securities may be subject to non-U.S. taxes. If more than 50% of the Fund's total assets at the close of its taxable year consists of stock or securities of foreign corporations, the Fund may elect for U.S. federal income tax purposes to treat foreign income taxes paid by it as paid by its shareholders. The Fund may qualify for and make this election in some, but not necessarily all, of its taxable years. If the Fund were to make such an election, shareholders would be required to take into account an amount equal to their pro rata portions of such foreign taxes in computing their taxable income and then treat an amount equal to those foreign taxes as a U.S. federal income tax deduction or as a foreign tax credit against their U.S. federal income tax liability. A taxpayer's ability to use a foreign tax deduction or credit is subject to limitations under the Code. Shortly after any year for which it makes such an election, the Fund will report to its shareholder the amount per share of such foreign income tax that must be included in each shareholder's gross income and the amount that may be available for the deduction or credit.

Foreign currency gain or loss on foreign currency exchange contracts, non-U.S. dollar-denominated securities contracts, and non-U.S. dollar-denominated futures contracts, options and forward contracts that are not section 1256 contracts (as defined below) generally will be treated as ordinary income and loss.

Income from options on individual securities written by the Fund will not be recognized by the Fund for tax purposes until an option is exercised, lapses or is subject to a "closing transaction" (as defined by applicable regulations) pursuant to which the Fund's obligations with respect to the option are otherwise terminated. If the option lapses without exercise, the premiums received by the Fund from the writing of such options will generally be characterized as short-term capital gain. If the Fund enters into a closing transaction, the difference between the premiums received and the amount paid by the Fund to close out its position will generally be treated as short-term capital gain or loss. If an option written by the Fund is exercised, thereby requiring the Fund to sell the underlying security, the premium will increase the amount realized upon the sale of the security, and the character of any gain on such sale of the underlying security as short-term or long-term capital gain will depend on the holding period of

II-97

the Fund in the underlying security. Because the Fund will not have control over the exercise of the options it writes, such exercises or other required sales of the underlying securities may cause the Fund to realize gains or losses at inopportune times.

Options on indices of securities and sectors of securities that qualify as "section 1256 contracts" will generally be "marked-to-market" for U.S. federal income tax purposes. As a result, the Fund will generally recognize gain or loss on the last day of each taxable year equal to the difference between the value of the option on that date and the adjusted basis of the option. The adjusted basis of the option will consequently be increased by such gain or decreased by such loss. Any gain or loss with respect to options on indices and sectors that qualify as "section 1256 contracts" will be treated as short-term capital gain or loss to the extent of 40% of such gain or loss and long-term capital gain or loss to the extent of 60% of such gain or loss. Because the mark-to-market rules may cause the Fund to recognize gain in advance of the receipt of cash, the Fund may be required to dispose of investments in order to meet its distribution requirements. "Mark-to-market" losses may be suspended or otherwise limited if such losses are part of a straddle or similar transaction.

Taxation of Common Shareholders. The Fund will either distribute or retain for reinvestment all or part of its net capital gain. If any such gain is retained, the Fund will be subject to a corporate income tax on such retained amount. In that event, the Fund expects to report the retained amount as undistributed capital gain in a notice to its common shareholders, each of whom, if subject to U.S. federal income tax on long-term capital gains, (i) will be required to include in income for U.S. federal income tax purposes as long-term capital gain its share of such undistributed amounts, (ii) will be entitled to credit its proportionate share of the tax paid by the Fund against its U.S. federal income tax liability and to claim refunds to the extent that the credit exceeds such liability and (iii) will increase its basis in its common shares by the amount of undistributed capital gains included in the shareholder's income less the tax deemed paid by the shareholder under clause (ii).

Distributions paid to you by the Fund from its net capital gain, if any, that the Fund properly reports as capital gain dividends ("capital gain dividends") are taxable as long-term capital gains, regardless of how long you have held your common shares. All other dividends paid to you by the Fund (including dividends from net short-term capital gains) from its current or accumulated earnings and profits ("ordinary income dividends") are generally subject to tax as ordinary income. Provided that certain holding period and other requirements are met, ordinary income dividends (if properly reported by the Fund) may qualify (i) for the dividends received deduction in the case of corporate shareholders to the extent that the Fund's income consists of dividend income from U.S. corporations, and (ii) in the case of individual shareholders, as "qualified dividend income" eligible to be taxed at long-term capital gains rates to the extent that the Fund receives qualified dividend income. Qualified dividend income is, in general, dividend income from taxable domestic corporations and certain qualified foreign corporations (e.g., generally, foreign corporations incorporated in a possession of the United States or in certain countries with a qualifying comprehensive tax treaty with the United States, or whose stock with respect to which such dividend is paid is readily tradable on an established securities market in the United States). The Fund does not expect that a significant portion of its distributions will consist of qualified dividend income or be eligible for the dividends received deduction.

Any distributions you receive that are in excess of the Fund's current and accumulated earnings and profits will be treated as a return of capital to the extent of your adjusted tax basis in your common shares, and thereafter as capital gain from the sale of common shares. The amount of any Fund distribution that is treated as a return of capital will reduce your adjusted tax basis in your common shares, thereby increasing your potential gain or reducing your potential loss on any subsequent sale or other disposition of your common shares.

Common shareholders may be entitled to offset their capital gain dividends with capital losses. The Code contains a number of statutory provisions affecting when capital losses may be offset against capital gain, and limiting the use of losses from certain investments and activities. Accordingly, common shareholders that have capital losses are urged to consult their tax advisers.

Dividends and other taxable distributions are taxable to you even though they are reinvested in additional common shares of the Fund. Dividends and other distributions paid by the Fund are generally treated under the Code as received by you at the time the dividend or distribution is made. If, however, the Fund pays you a dividend in January that was declared in the previous October, November or December to common shareholders of record on a specified date in one of such months, then such dividend will be treated for U.S. federal income tax purposes as

II-98

being paid by the Fund and received by you on December 31 of the year in which the dividend was declared. In addition, certain other distributions made after the close of the Fund's taxable year may be "spilled back" and treated as paid by the Fund (except for purposes of the 4% nondeductible excise tax) during such taxable year. In such case, you will be treated as having received such dividends in the taxable year in which the distributions were actually made.

The price of common shares purchased at any time may reflect the amount of a forthcoming distribution. Those purchasing common shares just prior to a distribution will receive a distribution which will be taxable to them even though it represents, economically, a return of invested capital.

The Fund will send you information after the end of each year setting forth the amount and tax status of any distributions paid to you by the Fund.

The sale or other disposition of common shares will generally result in capital gain or loss to you and will be long-term capital gain or loss if you have held such common shares for more than one year at the time of sale. Any loss upon the sale or other disposition of common shares held for six months or less will be treated as long-term capital loss to the extent of any capital gain dividends received (including amounts credited as an undistributed capital gain dividend) by you with respect to such common shares. Any loss you recognize on a sale or other disposition of common shares will be disallowed if you acquire other common shares (whether through the automatic reinvestment of dividends or otherwise) within a 61-day period beginning 30 days before and ending 30 days after your sale or exchange of the common shares. In such case, your tax basis in the common shares acquired will be adjusted to reflect the disallowed loss.

Current U.S. federal income tax law taxes both long-term and short-term capital gain of corporations at the rates applicable to ordinary income. For non-corporate taxpayers, short-term capital gain is currently taxed at rates applicable to ordinary income while long-term capital gain generally is taxed at a reduced maximum rate. The deductibility of capital losses is subject to limitations under the Code.

Certain U.S. holders who are individuals, estates or trusts and whose income exceeds certain thresholds will be required to pay a 3.8% Medicare tax on all or a portion of their "net investment income," which includes dividends received from the Fund and capital gains from the sale or other disposition of the Fund's stock.

A common shareholder that is a nonresident alien individual or a foreign corporation (a "foreign investor") generally will be subject to U.S. federal withholding tax at the rate of 30% (or possibly a lower rate provided by an applicable tax treaty) on ordinary income dividends (except as discussed below). In general, U.S. federal withholding tax and U.S. federal income tax will not apply to any gain or income realized by a foreign investor in respect of any distribution of net capital gain (including amounts credited as an undistributed capital gain dividend) or upon the sale or other disposition of common shares of the Fund. Different tax consequences may result if the foreign investor is engaged in a trade or business in the United States or, in the case of an individual, is present in the United States for 183 days or more during a taxable year and certain other conditions are met. Foreign investors should consult their tax advisers regarding the tax consequences of investing in the Fund's common shares.

For taxable years of a RIC beginning before January 1, 2014 (and, if extended as has happened in the past, for taxable years covered by such extension), ordinary income dividends properly reported by the RIC are generally exempt from U.S. federal withholding tax where they (i) are paid in respect of the RIC's "qualified net interest income" (generally, its U.S.-source interest income, other than certain contingent interest and interest from obligations of a corporation or partnership in which the RIC is at least a 10% shareholder, reduced by expenses that are allocable to such income) or (ii) are paid in respect of the RIC's "qualified short-term capital gains" (generally, the excess of the RIC's net short-term capital gain over its long-term capital loss for such taxable year). There can be no assurance as to whether this provision will be extended. In addition, depending on its circumstances, the Fund may report all, some or none of its potentially eligible dividends as such qualified net interest income or as qualified short-term capital gains, and/or treat such dividends, in whole or in part, as ineligible for this exemption from withholding. In order to qualify for this exemption from withholding, a foreign investor needs to comply with applicable certification requirements relating to its non-U.S. status (including, in general, furnishing an IRS Form W-8BEN or substitute Form). In the case of common shares held through an intermediary, the intermediary may have withheld even if the Fund reported the payment as qualified net interest income or qualified short-term capital gain. Foreign investors should contact their intermediaries with respect to the application of these rules to their

II-99

accounts. There can be no assurance as to what portion of the Fund's distributions would qualify for favorable treatment as qualified net interest income or qualified short-term capital gains if the provision is extended.

In addition, legislation enacted in 2010 and existing guidance issued thereunder will require, after June 30, 2014, withholding at a rate of 30% on dividends in respect of, and, after December 31, 2016, gross proceeds from the sale of, common stock of the Fund held by or through certain foreign financial institutions (including investment funds), unless such institution enters into an agreement with the Treasury to report, on an annual basis, information with respect to shares in, and accounts maintained by, the institution to the extent such shares or accounts are held by certain U.S. persons and by certain non-U.S. entities that are wholly or partially owned by U.S. persons and to withhold on certain payments. An intergovernmental agreement between the United States and an applicable foreign country, or future Treasury regulations or other guidance, may modify these requirements. Accordingly, the entity through which common stock of the Fund is held will affect the determination of whether such withholding is required. Similarly, dividends in respect of, and gross proceeds from the sale of, common stock of the Fund held by an investor that is a non-financial foreign entity that does not qualify under certain exemptions will be subject to withholding at a rate of 30%, unless such entity either (i) certifies that such entity does not have any "substantial United States owners" or (ii) provides certain information regarding the entity's "substantial United States owners," which the Fund will in turn provide to the Secretary of the Treasury. The Fund will not pay any additional amounts to stockholders in respect of any amounts withheld. Foreign investors are encouraged to consult with their tax advisers regarding the possible implications of these rules on their investment in the Fund's common shares.

U.S. federal backup withholding tax may be required on dividends, distributions and sale proceeds payable to certain non-exempt common shareholders who fail to supply their correct taxpayer identification number (in the case of individuals, generally, their social security number) or to make required certifications, or who are otherwise subject to backup withholding. Backup withholding is not an additional tax and any amount withheld may be refunded or credited against your U.S. federal income tax liability, if any, provided that you timely furnish the required information to the IRS.

Ordinary income dividends, capital gain dividends, and gain from the sale or other disposition of common shares of the Fund also may be subject to state, local, and/or foreign taxes. Common shareholders are urged to consult their own tax advisers regarding specific questions about U.S. federal, state, local or foreign tax consequences to them of investing in the Fund.

* * *

The foregoing is a general and abbreviated summary of certain provisions of the Code and the Treasury Regulations presently in effect as they directly govern the taxation of the Fund and its shareholders. For complete provisions, reference should be made to the pertinent Code sections and Treasury Regulations. The Code and the Treasury Regulations are subject to change by legislative or administrative action, and any such change may be retroactive with respect to Fund transactions. Holders of common shares are advised to consult their own tax advisers for more detailed information concerning the U.S. federal income taxation of the Fund and the income tax consequences to its holders of common shares.

Independent Trustees serve until their resignation, removal or death, or until December 31 of the year in which they turn 74. The maximum age limitation may be waived as to any Trustee by action of a majority of the Trustees upon finding a good cause therefor. In 2013, the Board unanimously approved extending the mandatory retirement age for James T. Flynn by one additional year, which the Board believed would be in the best interest of shareholders. Mr. Flynn can serve until December 31 of the year in which he turns 75. Mr. Flynn turns 75 in 2014.

(2)

Date shown is the earliest date a person has served for the funds in the Closed-End Complex. Following the combination of Merrill Lynch Investment Managers, L.P. ("MLIM") and BlackRock, Inc. ("BlackRock") in September 2006, the various legacy MLIM and legacy BlackRock fund boards were realigned and consolidated into three new fund boards in 2007. As a result, although the chart shows certain Trustees as joining the board of the Closed-End Complex in 2007, those Trustees first became members of the boards of other legacy MLIM or legacy BlackRock funds as follows: Richard E. Cavanagh, 1994; Frank J. Fabozzi, 1988; Kathleen F. Feldstein, 2005; James T. Flynn, 1996; Jerrold B. Harris, 1999; R. Glenn Hubbard, 2004; W. Carl Kester, 1995 and Karen P. Robards, 1998.

(3)

For purposes of this chart, "RICs" refers to investment companies registered under the 1940 Act and "Portfolios" refers to the investment programs of the BlackRock-Advised Funds. The Closed-End Complex, including the Fund, is comprised of 82 RICs. Mr. Audet and Mr. Gabbay are also board members of two complexes of BlackRock registered open-end funds, the BlackRock Equity-Liquidity Complex and the BlackRock Equity-Bond Complex. Dr. Fabozzi is also a board member of the BlackRock Equity-Liquidity Complex.

(4)

Directorships disclosed under this column do not include directorships disclosed under the column "Principal Occupation(s) During Past Five Years." Mr. Audet and Mr. Gabbay are also board members of two complexes of BlackRock registered open-end funds, the BlackRock Equity-Liquidity Complex and the BlackRock Equity-Bond Complex. Dr. Fabozzi is also a board member of the BlackRock Equity-Liquidity Complex.

(5)

Mr. Audet is an "interested person," as defined in the 1940 Act, of the Fund based on his position with BlackRock and its affiliates as well as his ownership of BlackRock securities. Mr. Gabbay is an "interested person" of the Fund based on his ownership of BlackRock and The PNC Financial Services Group, Inc. securities. Mr. Audet and Mr. Gabbay are also board members of two complexes of BlackRock registered open-end funds, the BlackRock Equity-Liquidity Complex and the BlackRock Equity-Bond Complex. Interested Trustees of the BlackRock Closed-End Complex serve until their resignation, removal or death, or until December 31 of the year in which they turn 72. The maximum age limitation may be waived as to any Trustee by action of a majority of the Trustees upon finding a good cause therefor.

Experience, Qualifications and Skills of the Trustees.

The Independent Trustees have adopted a statement of policy that describes the experience, qualifications, skills and attributes that are necessary and desirable for potential Independent Trustee candidates (the "Statement of Policy"). The Board believes that each Independent Trustee satisfied, at the time he or she was initially elected or appointed a Trustee, and continues to satisfy, the standards contemplated by the Statement of Policy. Furthermore, in determining that a particular Trustee was and continues to be qualified to serve as a Trustee, the Board has considered a variety of criteria, none of which, in isolation, was controlling. The Board believes that, collectively, the Trustees have balanced and diverse experience, skills, attributes and qualifications, which allow the Board to operate effectively in governing the Fund and protecting the interests of shareholders. Among the attributes common to all Trustees is their ability to review critically, evaluate, question and discuss information provided to them, to interact effectively with the Fund's investment advisor, sub-advisor, other service providers, counsel and independent registered public accounting firm, and to exercise effective business judgment in the performance of

II-102

their duties as Trustees. Each Trustee's ability to perform his or her duties effectively is evidenced by his or her educational background or professional training; business, consulting, public service or academic positions; experience from service as a trustee of the Fund or the other funds in the BlackRock fund complexes (and any predecessor funds), other investment funds, public companies, or non-profit entities or other organizations; ongoing commitment and participation in Board and committee meetings, as well as their leadership of standing and ad hoc committees throughout the years; or other relevant life experiences.

The table below discusses some of the experiences, qualifications and skills of each of the Fund's Trustees that support the conclusion that they should serve on the Board.

Trustee	Experience, Qualifications and Skills
Richard E. Cavanagh	Mr. Cavanagh brings to the Board a wealth of practical business knowledge and leadership as an experienced director/trustee of various public and private companies. In particular, because Mr. Cavanagh served for over a decade as President and Chief Executive Officer of The Conference Board, Inc., a global business research organization, he is able to provide the Board with expertise about business and economic trends and governance practices. Mr. Cavanagh created the "blue ribbon" Commission on Public Trust and Private Enterprise in 2002, which recommended corporate governance enhancements. Mr. Cavanagh's service as a director of The Guardian Life Insurance Company of America and as a senior advisor and director of The Fremont Group provides added insight into investment trends and conditions.

Board Leadership Structure and Oversight

The Board has overall responsibility for the oversight of the Fund. The Chair of the Board and the Chief Executive Officer are two different people. Not only is the Chair of the Board an Independent Trustee, but the Chair of each Board committee (each, a "Committee") is also an Independent Trustee. The Board has six standing Committees: an Audit Committee, a Governance and Nominating Committee, a Compliance Committee, a Performance Oversight Committee, an Executive Committee and a Leverage Committee. The role of the Chair of the Board is to preside at all meetings of the Board and to act as a liaison with service providers, officers, attorneys, and other Trustees between meetings. The Chair of each Committee performs a similar role with respect to such Committee. The Chair of the Board or Committees may also perform such other functions as may be delegated by the Board or the Committees from time to time. The Independent Trustees meet regularly outside the presence of the Fund's management, in executive session or with other service providers to the Fund. The Board has regular meetings five times a year, including a meeting to consider the approval of the Fund's Advisory Agreements, and may hold special meetings if required before their next regular meeting.

Each Committee meets regularly to conduct the oversight functions delegated to that Committee by the Board and reports its findings to the Board. The Board and each standing Committee conduct annual assessments of their oversight function and structure. The Board has determined that the Board's leadership structure is appropriate because it allows the Board to exercise independent judgment over management and to allocate areas of responsibility among Committees and the Board to enhance effective oversight.

The Board decided to separate the roles of Chair and Chief Executive Officer because it believes that an independent Chair:

Increases the independent oversight of the Fund and enhances the Board's objective evaluation of the Chief Executive Officer

Allows the Chief Executive Officer to focus on the Fund's operations instead of Board administration

Provides greater opportunities for direct and independent communication between shareholders and the Board

Provides an independent spokesman for the Fund

The Board has engaged the Investment Advisor to manage the Fund on a day-to day basis. The Board is responsible for overseeing the Investment Advisor, other service providers, the operations of the Fund and associated risks in accordance with the provisions of the 1940 Act, state law, other applicable laws, the Fund's charter, and the Fund's investment objective and strategies. The Board reviews, on an ongoing basis, the Fund's performance, operations, and investment strategies and techniques. The Board also conducts reviews of the Investment Advisor and its role in running the operations of the Fund.

Day-to-day risk management with respect to the Fund is the responsibility of the Investment Advisor or other service providers (depending on the nature of the risk), subject to the supervision of the Investment Advisor. The Fund is subject to a number of risks, including investment, compliance, operational and valuation risks, among others. While there are a number of risk management functions performed by the Investment Advisor or other service providers, as applicable, it is not possible to eliminate all of the risks applicable to the Fund. Risk oversight is part of the Board's general oversight of the Fund and is addressed as part of various Board and Committee activities. The Board, directly or through Committees, also review reports from, among others, management, the independent registered public accounting firm for the Fund, the Investment Advisor, and internal auditors for the

II-106

Investment Advisor or its affiliates, as appropriate, regarding risks faced by the Fund and management's or the service provider's risk functions. The Committee system facilitates the timely and efficient consideration of matters by the Trustees and facilitates effective oversight of compliance with legal and regulatory requirements and of the Fund's activities and associated risks. The Board has appointed a Chief Compliance Officer, who oversees the implementation and testing of the Fund's compliance program and reports regularly to the Board regarding compliance matters for the Fund and its service providers. The Independent Trustees have engaged independent legal counsel to assist them in performing their oversight responsibilities.

Audit Committee. The Board has a standing Audit Committee composed of Karen P. Robards (Chair), Michael J. Castellano, Frank J. Fabozzi, James T. Flynn and W. Carl Kester, all of whom are Independent Trustees. The principal responsibilities of the Audit Committee are to assist the Board in fulfilling its oversight responsibilities relating to the accounting and financial reporting policies and practices of the Fund. The Audit Committee's responsibilities include, without limitation: (i) approving and recommending to the full Board for approval the selection, retention, termination and compensation of the Fund's independent registered public accounting firm (the "Independent Registered Public Accounting Firm") and evaluating the independence and objectivity of the Independent Registered Public Accounting Firm; (ii) approving all audit engagement terms and fees for the Fund; (iii) reviewing the conduct and results of each audit; (iv) reviewing any issues raised by the Fund's Independent Registered Public Accounting Firm or management regarding the accounting or financial reporting policies and practices of the Fund, its internal controls, and, as appropriate, the internal controls of certain service providers and management's response to any such issues; (v) reviewing and discussing the Fund's audited and unaudited financial statements and disclosure in the Fund's shareholder reports relating to the Fund's performance; (vi) assisting the Board's responsibilities with respect to the internal controls of the Fund and its service providers with respect to accounting and financial matters; and (vii) resolving any disagreements between the Fund's management and the Fund's Independent Registered Public Accounting Firm regarding financial reporting. A copy of the Audit Committee Charter for the Fund can be found in the "Corporate Governance" section of the BlackRock Closed-End Fund website at www.blackrock.com.

Governance and Nominating Committee. The Board has a standing Governance and Nominating Committee composed of R. Glenn Hubbard (Chair), Richard E. Cavanagh, Michael J. Castellano, Frank J. Fabozzi, Kathleen F. Feldstein, James T. Flynn, Jerrold B. Harris, W. Carl Kester and Karen P. Robards, all of whom are Independent Trustees. The principal responsibilities of the Governance and Nominating Committee are: (i) identifying individuals qualified to serve as Independent Trustees and recommending Independent Trustee nominees for election by shareholders or appointment by the Board; (ii) advising the Board with respect to Board composition, procedures and committees of the Board (other than the Audit Committee); (iii) overseeing periodic self-assessments of the Board and committees of the Board (other than the Audit Committee); (iv) reviewing and making recommendations in respect of Independent Trustee compensation; (v) monitoring corporate governance matters and making recommendations in respect thereof to the Board; (vi) acting as the administrative committee with respect to Board policies and procedures, committee policies and procedures (other than the Audit Committee) and codes of ethics as they relate to the Independent Trustees; and (vii) review and make recommendations to the Board in respect of Fund share ownership by the Independent Trustees.

The Governance and Nominating Committee of the Board seeks to identify individuals to serve on the Board who have a diverse range of viewpoints, qualifications, experiences, backgrounds and skill sets so that the Board will be better suited to fulfill its responsibility of overseeing the Fund's activities. In so doing, the Governance and Nominating Committee reviews the size of the Board, the ages of the current Trustees and their tenure on the Board, and the skills, background and experiences of the Trustees in light of the issues facing the Fund in determining whether one or more new trustees should be added to the Board. The Board as a group strives to achieve diversity in terms of gender, race and geographic location. The Governance and Nominating Committee believes that the Trustees as a group possess the array of skills, experiences and backgrounds necessary to guide the Fund. The Trustees' biographies included above highlight the diversity and breadth of skills, qualifications and expertise that the Trustees bring to the Fund.

The Governance and Nominating Committee may consider nominations for Trustees made by the Fund's shareholders as it deems appropriate. Shareholders who wish to recommend a nominee should send a recommendation to the Fund's Secretary that includes all information relating to such person that is required to be disclosed in solicitations of proxies for the election of Trustees or is required by the advance notice provision of the

II-107

Fund's Bylaws. The Fund's Bylaws provide that notice of a proposed nomination must include certain information about the shareholder and the nominee, as well as a written consent of the proposed nominee to serve if elected. A notice of a proposed item of business must include a description of and the reasons for bringing the proposed business to the meeting, any material interest of the shareholder in the business, and certain other information about the shareholder. Further, the Fund has adopted Trustee qualification requirements which can be found in the Fund's Bylaws and are applicable to all Trustees that may be nominated, elected, appointed, qualified or seated to serve as Trustees. Reference is made to the Fund's Bylaws, which are on file with the SEC, for more details.

A copy of the Governance and Nominating Committee Charter for the Fund can be found in the "Corporate Governance" section of the BlackRock Closed-End Fund website at www.blackrock.com.

Compliance Committee. The Board has a Compliance Committee composed of Jerrold B. Harris (Chair), Richard E. Cavanagh, Kathleen F. Feldstein and R. Glenn Hubbard, each of whom are Independent Trustees. The Compliance Committee's purpose is to assist the Board in fulfilling its responsibility with respect to the oversight of regulatory and fiduciary compliance matters involving the Fund, the fund-related activities of BlackRock, and any sub-advisors and the Fund's other third party service providers. The Compliance Committee's responsibilities include, without limitation: (i) overseeing the compliance policies and procedures of the Fund and its service providers and recommending changes or additions to such policies and procedures; (ii) reviewing information on and, where appropriate, recommending policies concerning the Fund's compliance with applicable law; (iii) reviewing information on any significant correspondence with or other actions by regulators or governmental agencies with respect to the Fund and any employee complaints or published reports that raise concerns regarding compliance matters; and (iv) reviewing reports from, overseeing the annual performance review of, and making certain recommendations in respect of the Fund's Chief Compliance Officer, including, without limitation, determining the amount and structure of the Chief Compliance Officer's compensation.

Performance Oversight Committee. The Board has a Performance Oversight Committee composed of Frank J. Fabozzi (Chair), Richard E. Cavanagh, Michael J. Castellano, Kathleen F. Feldstein, James T. Flynn, Jerrold B. Harris, R. Glenn Hubbard, W. Carl Kester and Karen P. Robards, all of whom are Independent Trustees.

The Performance Oversight Committee's responsibilities include, without limitation: (i) reviewing the Fund's investment objective, policies and practices; (ii) recommending to the Board any required action in respect of changes in fundamental and non-fundamental investment restrictions; (iii) reviewing information on appropriate benchmarks and competitive universes; (iv) reviewing the Fund's investment performance relative to such benchmarks; (v) reviewing information on unusual or exceptional investment matters; (vi) reviewing whether the Fund has complied with its investment policies and restrictions; and (vii) overseeing policies, procedures and controls regarding valuation of the Fund's investments.

The Board has adopted a written charter for the Leverage Committee.

II-108

Trustee Share Ownership

As of December 31, 2013, none of the Independent Trustees of the Fund or their immediate family members owned beneficially or of record any securities of BlackRock or any affiliate of BlackRock or underwriter or any person controlling, controlled by or under common control with any such entities nor did any Independent Trustee of the Fund or their immediate family member have any material interest in any transaction, or series of similar transactions, during the most recently completed two calendar years involving the Fund, BlackRock or any affiliate of BlackRock or underwriter or any person controlling, controlled by or under common control with any such entities.

Trustee Compensation

Each Independent Trustee is paid an annual retainer of $250,000 per year for his or her services as a Trustee of all BlackRock-advised closed-end funds (the "Closed-End Complex") that are overseen by the respective director/trustee and each Trustee may also receive a $10,000 board meeting fee for special unscheduled meetings or meetings in excess of six Board meetings held in a calendar year, together with out-of-pocket expenses in accordance with a Board policy on travel and other business expenses relating to attendance at meetings. In addition, the Chair and Vice-Chair of the Board are paid an additional annual retainer of $120,000 and $40,000, respectively. The Chairs of the Audit Committee, Compliance Committee, Governance and Nominating Committee, and Performance Oversight Committee are paid an additional annual retainer of $35,000, $20,000, $10,000, and $20,000, respectively. Each Audit Committee and Leverage Committee member is paid an additional annual retainer of $25,000 for his or her service on such committee. For the year ended December 31, 2013, the Closed-End Complex reimbursed Independent Trustee expenses in an aggregate amount of $57,957. The Fund pays a pro rata portion quarterly (based on relative net assets) of the foregoing Trustee fees paid by the funds in the Closed-End Complex.

Mr. Gabbay is an interested person of the Fund and serves as an Interested Director of three groups of BlackRock-advised funds—the Closed-End Complex and two complexes of open-end funds (the "Equity-Liquidity Complex" and the "Equity-Bond Complex"; each such complex a "BlackRock Fund Complex"). Mr. Gabbay receives for his services as a Director of all BlackRock Fund Complexes (i) an annual retainer of $550,000, paid quarterly in arrears, allocated to the BlackRock-advised funds in these three BlackRock Fund Complexes, including the Fund, based on their relative net assets and (ii) with respect to each of the two open-end BlackRock Fund Complexes, a Board meeting fee of $3,750 (with respect to meetings of the Equity-Liquidity Complex) and $18,750 (with respect to meetings of the Equity-Bond Complex) to be paid for attendance at each Board meeting up to five Board meetings held in a calendar year by each such complex (compensation for meetings in excess of this number to be determined on a case-by-case basis). Mr. Gabbay is also reimbursed for out-of-pocket expenses in accordance with a Board policy on travel and other business expenses relating to attendance at meetings. Mr. Gabbay's compensation for serving on the boards of the funds in these three BlackRock Fund Complexes (including the Fund) is equal to 75% of each director retainer and, as applicable, of each Board meeting fee (without regard to additional fees paid to Board and Committee chairs) received by the Independent Directors serving on such boards, as well as the full Leverage Committee member retainer. The Board or the board of directors/trustees of any other BlackRock-advised fund in a BlackRock Fund Complex may modify the Directors' compensation from time to time depending on market conditions and Mr. Gabbay's compensation would be impacted by those modifications.

Dr. Fabozzi was appointed to serve as a member of the boards of the Equity-Liquidity Complex effective April 1, 2014. Dr. Fabozzi is paid a retainer of $206,250 for his services as a board member of all funds in the BlackRock Equity-Liquidity Complex for the remainder of 2014 (and an annual retainer of $275,000 per year thereafter). Dr. Fabozzi may also receive a $5,000 board meeting fee to be paid for each in-person board meeting attended (a $2,500 board meeting fee for telephonic attendance at regular board meetings), for up to five board meetings held in a calendar year (compensation for meetings in excess of this number to be determined on a case-by-case basis), together with out of pocket expenses in accordance with a board policy on travel and other business expenses relating to attendance at meetings. Dr. Fabozzi is currently a member of the audit committee and performance oversight committee of the BlackRock-advised funds in the Equity-Liquidity Complex. Dr. Fabozzi receives $7,500 for each standing committee on which he serves for the remainder of 2014 (and $10,000 per year thereafter) for up to two standing Committee assignments but is not paid this amount for serving on a committee which he chairs. Dr. Fabozzi was paid a consulting fee of $50,000 for attending a board meeting of the Equity-Liquidity Complex in February 2014. The boards of the Funds or of any other BlackRock-advised fund in a

II-109

BlackRock Fund Complex may modify the board members' compensation from time to time depending on market conditions and accordingly Dr. Fabozzi's compensation would be impacted by those modifications.

The Independent Trustees have agreed that a maximum of 50% of each Independent Trustee's total compensation paid by funds in the Closed-End Complex may be deferred pursuant to the Closed-End Complex's deferred compensation plan. Under the deferred compensation plan, deferred amounts earn a return for the Independent Trustees as though equivalent dollar amounts had been invested in common shares of certain funds in the Closed-End Complex selected by the Independent Trustees. This has approximately the same economic effect for the Independent Trustees as if they had invested the deferred amounts in such funds in the Closed-End Complex. The deferred compensation plan is not funded and obligations thereunder represent general unsecured claims against the general assets of a fund and are recorded as a liability for accounting purposes.

Indemnification of Trustees and Officers

The governing documents of the Fund generally provide that, to the extent permitted by applicable law, the Fund will indemnify its Trustees and officers against liabilities and expenses incurred in connection with litigation in which they may be involved because of their offices with the Fund unless, as to liability to the Fund or its investors, it is finally adjudicated that they engaged in willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in their offices. In addition, the Fund will not indemnify Trustees with respect to any matter as to which Trustees did not act in good faith in the reasonable belief that his or her action was in the best interest of the Fund or, in the case of any criminal proceeding, as to which Trustees had reasonable cause to believe that the conduct was unlawful. Indemnification provisions contained in the Fund's governing documents are subject to any limitations imposed by applicable law.

The funds in the Closed-End Complex, including the Fund, have also entered into a separate indemnification agreement with the board members of each board of such funds (the "Indemnification Agreement"). The Indemnification Agreement (i) extends the indemnification provisions contained in a fund's governing documents to board members who leave that fund's board and serve on an advisory board of a different fund in the Closed-End Complex; (ii) sets in place the terms of the indemnification provisions of a fund's governing documents once a board member retires from a board; and (iii) in the case of board members who left the board of a fund in connection with or prior to the board consolidation that occurred in 2007 as a result of the merger of BlackRock and Merrill Lynch & Co., Inc.'s investment management business, clarifies that such fund continues to indemnify the trustee for claims arising out of his or her past service to that fund.

Proxy Voting Policies

The Board has delegated the voting of proxies for the Fund's securities to the Investment Advisor pursuant to the Investment Advisor's proxy voting guidelines. Under these guidelines, the Investment Advisor will vote proxies related to Fund securities in the best interests of the Fund and its shareholders. From time to time, a vote may present a conflict between the interests of the Fund's shareholders, on the one hand, and those of the Investment Advisor, or any affiliated person of the Fund or the Investment Advisor, on the other. In such event, provided that the Investment Advisor's Equity Investment Policy Oversight Committee, or a sub-committee thereof (the "Oversight Committee") is aware of the real or potential conflict, if the matter to be voted on represents a material, non-routine matter and if the Oversight Committee does not reasonably believe it is able to follow its general voting guidelines (or if the particular proxy matter is not addressed in the guidelines) and vote impartially, the Oversight Committee may retain an independent fiduciary to advise the Oversight Committee on how to vote or to cast votes on behalf of the Investment Advisor's clients. If the Investment Advisor determines not to retain an independent fiduciary, or does not desire to follow the advice of such independent fiduciary, the Oversight Committee shall determine how to vote the proxy after consulting with the Investment Advisor's Portfolio Management Group and/or the Investment Advisor's Legal and Compliance Department and concluding that the vote cast is in its client's best interest notwithstanding the conflict.

A copy of the Fund's Proxy Voting Policy and Procedures is included as Appendix B to this Prospectus. Information regarding how the Fund voted proxies relating to portfolio securities for the 12-month period ending June 30 will be available (i) without charge, upon request, by calling (800) 882-0052; and (ii) on the SEC's website at http://www.sec.gov.

Code of Ethics

The Fund and the Investment Advisor have adopted codes of ethics pursuant to Rule 17j-1 under the 1940 Act. These codes permit personnel subject to the codes to invest in securities, including securities that may be purchased or held by the Fund. These codes can be reviewed and copied at the SEC's Public Reference Room in Washington, D.C. Information on the operation of the Public Reference Room may be obtained by calling the SEC at (202) 551-8090. These codes of ethics are available on the EDGAR Database on the SEC's website (http://www.sec.gov), and copies of these codes may be obtained, after paying a duplicating fee, by electronic

Conflicts of Interest

The PNC Financial Services Group, Inc. ("PNC") has a significant economic interest in BlackRock, Inc., the parent of the Investment Advisor. PNC is considered to be an affiliate of BlackRock, Inc., under the 1940 Act. Certain activities of the Investment Advisor, BlackRock, Inc. and their affiliates (collectively, "BlackRock") and PNC and its affiliates (collectively, "PNC" and together with BlackRock, "Affiliates") with respect to the Fund and/or other accounts managed by BlackRock or PNC may give rise to actual or perceived conflicts of interest such as those described below.

BlackRock is one of the world's largest asset management firms. PNC is a diversified financial services organization spanning the retail, business and corporate markets. BlackRock, PNC and their respective affiliates (including, for these purposes, their directors, partners, trustees, managing members, officers and employees), including the entities and personnel who may be involved in the investment activities and business operations of the Fund, are engaged worldwide in businesses, including equity, fixed income, cash management and alternative investments, and have interests other than that of managing the Fund. These are considerations of which investors in the Fund should be aware, and which may cause conflicts of interest that could disadvantage the Fund and its shareholders. These activities and interests include potential multiple advisory, transactional, financial and other interests in securities and other instruments, and companies that may be purchased or sold by the Fund.

BlackRock and its Affiliates have proprietary interests in, and may manage or advise with respect to, accounts or funds (including separate accounts and other funds and collective investment vehicles) that have investment objectives similar to those of the Fund and/or that engage in transactions in the same types of securities, currencies and instruments as the Fund. One or more Affiliates are also major participants in the global currency, equities, swap and fixed income markets, in each case both on a proprietary basis and for the accounts of customers. As such, one or more Affiliates are or may be actively engaged in transactions in the same securities, currencies, and instruments in which the Fund invests. Such activities could affect the prices and availability of the securities, currencies, and instruments in which the Fund invests, which could have an adverse impact on the Fund's performance. Such transactions, particularly in respect of most proprietary accounts or customer accounts, will be executed independently of the Fund's transactions and thus at prices or rates that may be more or less favorable than those obtained by the Fund.

When BlackRock and its Affiliates seek to purchase or sell the same assets for their managed accounts, including the Fund, the assets actually purchased or sold may be allocated among the accounts on a basis determined in their good faith discretion to be equitable. In some cases, this system may adversely affect the size or price of the assets purchased or sold for the Fund. In addition, transactions in investments by one or more other accounts managed by BlackRock or its Affiliates may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Fund, particularly, but not limited to, with respect to small capitalization, emerging market or less liquid strategies. This may occur when investment decisions regarding the Fund are based on research or other information that is also used to support decisions for other accounts. When BlackRock or its Affiliates implements a portfolio decision or strategy on behalf of another account ahead of, or contemporaneously with, similar decisions or strategies for the Fund, market impact, liquidity constraints, or other factors could result in the Fund receiving less favorable trading results and the costs of implementing such decisions or strategies could be increased or the Fund could otherwise be disadvantaged. BlackRock or its Affiliates may, in certain cases, elect to

II-112

implement internal policies and procedures designed to limit such consequences, which may cause the Fund to be unable to engage in certain activities, including purchasing or disposing of securities, when it might otherwise be desirable for it to do so.

Conflicts may also arise because portfolio decisions regarding the Fund may benefit other accounts managed by BlackRock or its Affiliates. For example, the sale of a long position or establishment of a short position by the Fund may impair the price of the same security sold short by (and therefore benefit) one or more Affiliates or their other accounts, and the purchase of a security or covering of a short position in a security by the Fund may increase the price of the same security held by (and therefore benefit) one or more Affiliates or their other accounts.

BlackRock and its Affiliates and their clients may pursue or enforce rights with respect to an issuer in which the Fund has invested, and those activities may have an adverse effect on the Fund. As a result, prices, availability, liquidity and terms of the Fund's investments may be negatively impacted by the activities of BlackRock or its Affiliates or their clients, and transactions for the Fund may be impaired or effected at prices or terms that may be less favorable than would otherwise have been the case.

The results of the Fund's investment activities may differ significantly from the results achieved by BlackRock and its Affiliates for their proprietary accounts or other accounts (including investment companies or collective investment vehicles) managed or advised by them. It is possible that one or more Affiliate-managed accounts and such other accounts will achieve investment results that are substantially more or less favorable than the results achieved by the Fund. Moreover, it is possible that the Fund will sustain losses during periods in which one or more Affiliates or Affiliate-managed accounts achieve significant profits on their trading for proprietary or other accounts. The opposite result is also possible. The investment activities of one or more Affiliates for their proprietary accounts and accounts under their management may also limit the investment opportunities for the Fund in certain emerging and other markets in which limitations are imposed upon the amount of investment, in the aggregate or in individual issuers, by affiliated foreign investors.

From time to time, the Fund's activities may also be restricted because of regulatory restrictions applicable to one or more Affiliates and/or their internal policies designed to comply with such restrictions. As a result, there may be periods, for example, when BlackRock, and/or one or more Affiliates, will not initiate or recommend certain types of transactions in certain securities or instruments with respect to which BlackRock and/or one or more Affiliates are performing services or when position limits have been reached.

In connection with its management of the Fund, BlackRock may have access to certain fundamental analysis and proprietary technical models developed by one or more Affiliates. BlackRock will not be under any obligation, however, to effect transactions on behalf of the Fund in accordance with such analysis and models. In addition, neither BlackRock nor any of its Affiliates will have any obligation to make available any information regarding their proprietary activities or strategies, or the activities or strategies used for other accounts managed by them, for the benefit of the management of the Fund and it is not anticipated that BlackRock will have access to such information for the purpose of managing the Fund. The proprietary activities or portfolio strategies of BlackRock and its Affiliates, or the activities or strategies used for accounts managed by them or other customer accounts could conflict with the transactions and strategies employed by BlackRock in managing the Fund.

In addition, certain principals and certain employees of the Investment Advisor are also principals or employees of BlackRock or another Affiliate. As a result, the performance by these principals and employees of their obligations to such other entities may be a consideration of which investors in the Fund should be aware.

BlackRock may enter into transactions and invest in securities, instruments and currencies on behalf of the Fund in which customers of BlackRock or its Affiliates, or, to the extent permitted by the SEC, BlackRock or another Affiliate, serves as the counterparty, principal or issuer. In such cases, such party's interests in the transaction will be adverse to the interests of the Fund, and such party may have no incentive to assure that the Fund obtains the best possible prices or terms in connection with the transactions. In addition, the purchase, holding and sale of such investments by the Fund may enhance the profitability of BlackRock or its Affiliates. One or more Affiliates may also create, write or issue derivatives for their customers, the underlying securities, currencies or instruments of which may be those in which the Fund invests or which may be based on the performance of the Fund. The Fund may, subject to applicable law, purchase investments that are the subject of an underwriting or other

II-113

distribution by one or more Affiliates and may also enter into transactions with other clients of an Affiliate where such other clients have interests adverse to those of the Fund.

At times, these activities may cause departments of BlackRock or its Affiliates to give advice to clients that may cause these clients to take actions adverse to the interests of the Fund. To the extent affiliated transactions are permitted, the Fund will deal with BlackRock and its Affiliates on an arms-length basis. BlackRock or its Affiliates may also have an ownership interest in certain trading or information systems used by the Fund. The Fund's use of such trading or information systems may enhance the profitability of BlackRock and its Affiliates.

One or more Affiliates may act as broker, dealer, agent, lender or adviser or in other commercial capacities for the Fund. It is anticipated that the commissions, mark-ups, mark-downs, financial advisory fees, underwriting and placement fees, sales fees, financing and commitment fees, brokerage fees, other fees, compensation or profits, rates, terms and conditions charged by an Affiliate will be in its view commercially reasonable, although each Affiliate, including its sales personnel, will have an interest in obtaining fees and other amounts that are favorable to the Affiliate and such sales personnel.

Subject to applicable law, the Affiliates (and their personnel and other distributors) will be entitled to retain fees and other amounts that they receive in connection with their service to the Fund as broker, dealer, agent, lender, adviser or in other commercial capacities and no accounting to the Fund or its shareholders will be required, and no fees or other compensation payable by the Fund or its shareholders will be reduced by reason of receipt by an Affiliate of any such fees or other amounts.

When an Affiliate acts as broker, dealer, agent, adviser or in other commercial capacities in relation to the Fund, the Affiliate may take commercial steps in its own interests, which may have an adverse effect on the Fund. The Fund will be required to establish business relationships with its counterparties based on the Fund's own credit standing. Neither BlackRock nor any of the Affiliates will have any obligation to allow their credit to be used in connection with the Fund's establishment of its business relationships, nor is it expected that the Fund's counterparties will rely on the credit of BlackRock or any of the Affiliates in evaluating the Fund's creditworthiness.

Purchases and sales of securities for the Fund may be bunched or aggregated with orders for other BlackRock client accounts. BlackRock and its Affiliates, however, are not required to bunch or aggregate orders if portfolio management decisions for different accounts are made separately, or if they determine that bunching or aggregating is not practicable, required or with cases involving client direction.

Prevailing trading activity frequently may make impossible the receipt of the same price or execution on the entire volume of securities purchased or sold. When this occurs, the various prices may be averaged, and the Fund will be charged or credited with the average price. Thus, the effect of the aggregation may operate on some occasions to the disadvantage of the Fund. In addition, under certain circumstances, the Fund will not be charged the same commission or commission equivalent rates in connection with a bunched or aggregated order.

BlackRock may select brokers (including, without limitation, Affiliates) that furnish BlackRock, the Fund, other BlackRock client accounts or other Affiliates or personnel, directly or through correspondent relationships, with research or other appropriate services which provide, in BlackRock's view, appropriate assistance to BlackRock in the investment decision-making process (including with respect to futures, fixed price offerings and over-the-counter transactions). Such research or other services may include, to the extent permitted by law, research reports on companies, industries and securities; economic and financial data; financial publications; proxy analysis; trade industry seminars; computer data bases; research-oriented software and other services and products.

Research or other services obtained in this manner may be used in servicing the Fund and other BlackRock client accounts, including in connection with BlackRock client accounts other than those that pay commissions to the broker relating to the research or other service arrangements. Such products and services may disproportionately benefit other BlackRock client accounts relative to the Fund based on the amount of brokerage commissions paid by the Fund and such other BlackRock client accounts. For example, research or other services that are paid for through one client's commissions may not be used in managing that client's account. In addition, other BlackRock client accounts may receive the benefit, including disproportionate benefits, of economies of scale or price discounts in connection with products and services that may be provided to the Fund and to such other BlackRock client accounts. To the extent that BlackRock uses soft dollars, it will not have to pay for those products and services itself.

II-114

BlackRock may receive research that is bundled with the trade execution, clearing, and/or settlement services provided by a particular broker-dealer. To the extent that BlackRock receives research on this basis, many of the same conflicts related to traditional soft dollars may exist. For example, the research effectively will be paid by client commissions that also will be used to pay for the execution, clearing, and settlement services provided by the broker-dealer and will not be paid by BlackRock.

BlackRock may endeavor to execute trades through brokers who, pursuant to such arrangements, provide research or other services in order to ensure the continued receipt of research or other services BlackRock believes are useful in its investment decision-making process. BlackRock may from time to time choose not to engage in the above described arrangements to varying degrees. BlackRock may also enter into commission sharing arrangements under which BlackRock may execute transactions through a broker-dealer, including, where permitted, an Affiliate, and request that the broker-dealer allocate a portion of the commissions or commission credits to another firm that provides research to BlackRock. To the extent that BlackRock engages in commission sharing arrangements, many of the same conflicts related to traditional soft dollars may exist.

BlackRock may utilize certain electronic crossing networks ("ECNs") in executing client securities transactions for certain types of securities. These ECNs may charge fees for their services, including access fees and transaction fees. The transaction fees, which are similar to commissions or markups/markdowns, will generally be charged to clients and, like commissions and markups/markdowns, would generally be included in the cost of the securities purchased. Access fees may be paid by BlackRock even though incurred in connection with executing transactions on behalf of clients, including the Fund. In certain circumstances, ECNs may offer volume discounts that will reduce the access fees typically paid by BlackRock. This would have the effect of reducing the access fees paid by BlackRock. BlackRock will only utilize ECNs consistent with its obligation to seek to obtain best execution in client transactions.

BlackRock has adopted policies and procedures designed to prevent conflicts of interest from influencing proxy voting decisions that it makes on behalf of advisory clients, including the Fund, and to help ensure that such decisions are made in accordance with BlackRock's fiduciary obligations to its clients. Nevertheless, notwithstanding such proxy voting policies and procedures, actual proxy voting decisions of BlackRock may have the effect of favoring the interests of other clients or businesses of other divisions or units of BlackRock and/or its Affiliates, provided that BlackRock believes such voting decisions to be in accordance with its fiduciary obligations. For a more detailed discussion of these policies and procedures, see "Proxy Voting Policies" under Item 18 in this Part II.

It is also possible that, from time to time, BlackRock or its Affiliates may, although they are not required to, purchase and hold shares of the Fund. Increasing the Fund's assets may enhance investment flexibility and diversification and may contribute to economies of scale that tend to reduce the Fund's expense ratio.

It is possible that the Fund may invest in securities of companies with which an Affiliate has or is trying to develop investment banking relationships as well as securities of entities in which BlackRock or its Affiliates has significant debt or equity investments or in which an Affiliate makes a market. The Fund also may invest in securities of companies to which an Affiliate provides or may someday provide research coverage. Such investments could cause conflicts between the interests of the Fund and the interests of other clients of BlackRock or its Affiliates. In making investment decisions for the Fund, BlackRock is not permitted to obtain or use material non-public information acquired by any division, department or Affiliate of BlackRock in the course of these activities. In addition, from time to time, the activities of an Affiliate may limit the Fund's flexibility in purchases and sales of securities. When an Affiliate is engaged in an underwriting or other distribution of securities of an entity, BlackRock may be prohibited from purchasing or recommending the purchase of certain securities of that entity for the Fund.

BlackRock and its Affiliates, their personnel and other financial service providers have interests in promoting sales of the Fund. With respect to BlackRock and its Affiliates and their personnel, the remuneration and profitability relating to services to and sales of the Fund or other products may be greater than remuneration and profitability relating to services to and sales of certain funds or other products that might be provided or offered. BlackRock and its Affiliates and their sales personnel may directly or indirectly receive a portion of the fees and commissions charged to the Fund or its shareholders. BlackRock and its advisory or other personnel may also benefit from increased amounts of assets under management. Fees and commissions may also be higher than for other products or services, and the remuneration and profitability to BlackRock or its Affiliates and such personnel

II-115

resulting from transactions on behalf of or management of the Fund may be greater than the remuneration and profitability resulting from other funds or products.

BlackRock and its Affiliates and their personnel may receive greater compensation or greater profit in connection with an account for which BlackRock serves as an adviser than with an account advised by an unaffiliated investment adviser. Differentials in compensation may be related to the fact that BlackRock may pay a portion of its advisory fee to its Affiliate, or relate to compensation arrangements, including for portfolio management, brokerage transactions or account servicing. Any differential in compensation may create a financial incentive on the part of BlackRock or its Affiliates and their personnel to recommend BlackRock over unaffiliated investment advisers or to effect transactions differently in one account over another.

BlackRock and its Affiliates may provide valuation assistance to certain clients with respect to certain securities or other investments and the valuation recommendations made for their clients' accounts may differ from the valuations for the same securities or investments assigned by the Fund's pricing vendors, especially if such valuations are based on broker-dealer quotes or other data sources unavailable to the Fund's pricing vendors. While BlackRock will generally communicate its valuation information or determinations to the Fund's pricing vendors and/or fund accountants, there may be instances where the Fund's pricing vendors or fund accountants assign a different valuation to a security or other investment than the valuation for such security or investment determined or recommended by BlackRock.

As disclosed in more detail in "Net Asset Value" in Item 10, when market quotations of direct investments are not readily available or are believed by BlackRock to be unreliable, the Fund's investments may be valued at fair value by BlackRock, pursuant to procedures adopted by the Board. When determining an asset's "fair value," BlackRock seeks to determine the price that the Fund might reasonably expect to receive from the current sale of that asset in an arm's-length transaction. The price generally may not be determined based on what the Fund might reasonably expect to receive for selling an asset at a later time or if it holds the asset to maturity. While fair value determinations will be based upon all available factors that BlackRock deems relevant at the time of the determination, and may be based on analytical values determined by BlackRock using proprietary or third party valuation models, fair value represents only a good faith approximation of the value of a security. The fair value of one or more securities may not, in retrospect, be the price at which those assets could have been sold during the period in which the particular fair values were used in determining the Fund's NAV. As a result, the Fund's sale or repurchase of its shares at NAV, at a time when a holding or holdings are valued by BlackRock (pursuant to Board-adopted procedures) at fair value, may have the effect of diluting or increasing the economic interest of existing shareholders.

To the extent permitted by applicable law, the Fund may invest all or some of its short term cash investments in any money market fund or similarly-managed private fund advised or managed by BlackRock. In connection with any such investments, the Fund, to the extent permitted by the 1940 Act, may pay its share of expenses of a money market fund in which it invests, which may result in the Fund bearing some additional expenses.

BlackRock and its Affiliates and their directors, officers and employees, may buy and sell securities or other investments for their own accounts, and may have conflicts of interest with respect to investments made on behalf of the Fund. As a result of differing trading and investment strategies or constraints, positions may be taken by directors, officers, employees and Affiliates of BlackRock that are the same, different from or made at different times than positions taken for the Fund. To lessen the possibility that the Fund will be adversely affected by this personal trading, the Fund, the Distributor and BlackRock each have adopted a Code of Ethics in compliance with Section 17(j) of the 1940 Act that restricts securities trading in the personal accounts of investment professionals and others who normally come into possession of information regarding the Fund's portfolio transactions.

BlackRock and its Affiliates will not purchase securities or other property from, or sell securities or other property to, the Fund, except that the Fund may in accordance with rules adopted under the 1940 Act engage in transactions with accounts that are affiliated with the Fund as a result of common officers, directors, or investment advisers or pursuant to exemptive orders granted to the Fund and/or BlackRock by the SEC. These transactions would be affected in circumstances in which BlackRock determined that it would be appropriate for the Fund to purchase and another client of BlackRock to sell, or the Fund to sell and another client of BlackRock to purchase, the same security or instrument on the same day. From time to time, the activities of the Fund may be restricted

II-116

because of regulatory requirements applicable to BlackRock or its Affiliates and/or BlackRock's internal policies designed to comply with, limit the applicability of, or otherwise relate to such requirements. A client not advised by BlackRock would not be subject to some of those considerations. There may be periods when BlackRock may not initiate or recommend certain types of transactions, or may otherwise restrict or limit their advice in certain securities or instruments issued by or related to companies for which an Affiliate is performing investment banking, market making, advisory or other services or has proprietary positions. For example, when an Affiliate is engaged in an underwriting or other distribution of securities of, or advisory services for, a company, the Fund may be prohibited from or limited in purchasing or selling securities of that company. In addition, when BlackRock is engaged to provide advisory or risk management services for a company, BlackRock may be prohibited from or limited in purchasing or selling securities of that company on behalf of the Fund, particularly where such services result in BlackRock obtaining material non-public information about the company. Similar situations could arise if personnel of BlackRock or its Affiliates serve as directors of companies the securities of which the Fund wishes to purchase or sell. However, if permitted by applicable law, and where consistent with BlackRock's policies and procedures (including the necessary implementation of appropriate information barriers), the Fund may purchase securities or instruments that are issued by such companies, are the subject of an underwriting, distribution, or advisory assignment by an Affiliate, or are the subject of an advisory or risk management assignment by BlackRock, or where personnel of BlackRock or its Affiliates are directors or officers of the issuer.

In certain circumstances where the Fund invests in securities issued by companies that operate in certain regulated industries, in certain emerging or international markets, or are subject to corporate or regulatory ownership definitions, there may be limits on the aggregate amount invested by Affiliates (including BlackRock) for their proprietary accounts and for client accounts (including the Fund) that may not be exceeded without the grant of a license or other regulatory or corporate consent, or, if exceeded, may cause BlackRock, the Fund or other client accounts to suffer disadvantages or business restrictions. As a result, BlackRock on behalf of its clients (including the Fund) may limit purchases, sell existing investments, or otherwise restrict or limit the exercise of rights (including voting rights) when BlackRock, in its sole discretion, deems it appropriate in light of potential regulatory or other restrictions on ownership or other consequences resulting from reaching investment thresholds.

In those circumstances where ownership thresholds or limitations must be observed, BlackRock seeks to allocate limited investment opportunities equitably among clients (including the Fund), taking into consideration benchmark weight and investment strategy. When ownership in certain securities nears an applicable threshold, BlackRock may limit purchases in such securities to the issuer's weighting in the applicable benchmark used by BlackRock to manage the Fund. If client (including Fund) holdings of an issuer exceed an applicable threshold and BlackRock is unable to obtain relief to enable the continued holding of such investments, it may be necessary to sell down these positions to meet the applicable limitations. In these cases, benchmark overweight positions will be sold prior to benchmark positions being reduced to meet applicable limitations.

In addition to the foregoing, other ownership thresholds may trigger reporting requirements to governmental and regulatory authorities, and such reports may entail the disclosure of the identity of a client or BlackRock's intended strategy with respect to such security or asset.

BlackRock and its Affiliates may maintain securities indices as part of their product offerings. Index based funds seek to track the performance of securities indices and may use the name of the index in the fund name. Index providers, including BlackRock and its Affiliates may be paid licensing fees for use of their index or index name. BlackRock and its Affiliates will not be obligated to license their indices to BlackRock, and BlackRock cannot be assured that the terms of any index licensing agreement with BlackRock and its Affiliates will be as favorable as those terms offered to other index licensees.

BlackRock and its Affiliates may serve as Authorized Participants in the creation and redemption of ETFs, including funds advised by affiliates of BlackRock. BlackRock and its Affiliates may therefore be deemed to be participants in a distribution of such ETFs, which could render them statutory underwriters.

Custody arrangements may lead to potential conflicts of interest with BlackRock where BlackRock has agreed to waive fees and/or reimburse ordinary operating expenses in order to cap expenses of the Fund. This is because the custody arrangements with the Fund's custodian may have the effect of reducing custody fees when the Fund leaves cash balances uninvested. When the Fund's actual operating expense ratio exceeds a stated cap, a reduction in custody fees reduces the amount of waivers and/or reimbursements BlackRock would be required to

II-117

make to the Fund. This could be viewed as having the potential to provide BlackRock an incentive to keep high positive cash balances for a fund with an expense cap in order to offset fund custody fees that BlackRock might otherwise reimburse. However, BlackRock's portfolio managers do not intentionally keep uninvested balances high, but rather make investment decisions that they anticipate will be beneficial to fund performance.

Present and future activities of BlackRock and its Affiliates, including the Investment Advisor, in addition to those described in this section, may give rise to additional conflicts of interest.

Item 21. Portfolio Managers

Potential Material Conflicts of Interest

BlackRock has built a professional working environment, firm-wide compliance culture and compliance procedures and systems designed to protect against potential incentives that may favor one account over another. BlackRock has adopted policies and procedures that address the allocation of investment opportunities, execution of portfolio transactions, personal trading by employees and other potential conflicts of interest that are designed to ensure that all client accounts are treated equitably over time. Nevertheless, BlackRock furnishes investment management and advisory services to numerous clients in addition to the Fund, and BlackRock may, consistent with applicable law, make investment recommendations to other clients or accounts (including accounts which are hedge funds or have performance or higher fees paid to BlackRock, or in which portfolio managers have a personal interest in the receipt of such fees), which may be the same as or different from those made to the Fund. In addition, BlackRock, Inc., its affiliates and significant shareholders and any officer, director, shareholder or employee may or may not have an interest in the securities whose purchase and sale BlackRock recommends to the Fund. BlackRock, Inc., or any of its affiliates or significant shareholders, or any officer, director, shareholder, employee or any member of their families may take different actions than those recommended to the Fund by BlackRock with respect to the same securities. Moreover, BlackRock may refrain from rendering any advice or services concerning securities of companies of which any of BlackRock, Inc.'s (or its affiliates' or significant shareholders') officers, directors or employees are directors or officers, or companies as to which BlackRock, Inc. or any of its affiliates or significant shareholders or the officers, directors and employees of any of them has any substantial economic interest or possesses material non-public information. Certain portfolio managers also may manage accounts whose investment strategies may at times be opposed to the strategy utilized for a fund.

As a fiduciary, BlackRock owes a duty of loyalty to its clients and must treat each client fairly. When BlackRock purchases or sells securities for more than one account, the trades must be allocated in a manner consistent with its fiduciary duties. BlackRock attempts to allocate investments in a fair and equitable manner among client accounts, with no account receiving preferential treatment. To this end, BlackRock, Inc. has adopted policies that are intended to ensure reasonable efficiency in client transactions and provide BlackRock with sufficient flexibility to allocate investments in a manner that is consistent with the particular investment discipline and client base, as appropriate.

Portfolio Manager Compensation Overview

BlackRock's financial arrangements with its portfolio managers, its competitive compensation and its career path emphasis at all levels reflect the value senior management places on key resources. Compensation may include a variety of components and may vary from year to year based on a number of factors. The principal components of compensation include a base salary, a performance-based discretionary bonus, participation in various benefits programs and one or more of the incentive compensation programs established by BlackRock. The following information is as of August 31, 2014.

Base Compensation. Generally, portfolio managers receive base compensation based on their position with BlackRock, Inc.

Discretionary Incentive Compensation. Discretionary incentive compensation is a function of several components: the performance of BlackRock, Inc., the performance of the portfolio manager's group within BlackRock, the investment performance, including risk-adjusted returns, of the firm's assets under management or supervision by that portfolio manager relative to

II-118

predetermined benchmarks, and the individual's performance and contribution to the overall performance of these portfolios and BlackRock. In most cases, these benchmarks are the same as the benchmark or benchmarks against which the performance of the Fund or other accounts managed by the portfolio managers are measured.

Distribution of Discretionary Incentive Compensation. Discretionary incentive compensation is distributed to portfolio managers in a combination of cash and BlackRock, Inc. restricted stock units which vest ratably over a number of years. For some portfolio managers, discretionary incentive compensation is also distributed in deferred cash awards that notionally track the returns of select BlackRock investment products they manage and that vest ratably over a number of years. The BlackRock, Inc. restricted stock units, upon vesting, will be settled in BlackRock, Inc. common stock. Typically, the cash portion of the discretionary incentive compensation, when combined with base salary, represents more than 60% of total compensation for the portfolio managers. Paying a portion of discretionary incentive compensation in BlackRock, Inc. stock puts compensation earned by a portfolio manager for a given year "at risk" based on BlackRock's ability to sustain and improve its performance over future periods. Providing a portion of discretionary incentive compensation in deferred cash awards that notionally track the BlackRock investment products they manage provides direct alignment with investment product results.

Long-Term Incentive Plan Awards — From time to time long-term incentive equity awards are granted to certain key employees to aid in retention, align their interests with long-term shareholder interests and motivate performance. Equity awards are generally granted in the form of BlackRock, Inc. restricted stock units that, once vested, settle in BlackRock, Inc. common stock.

Deferred Compensation Program — A portion of the compensation paid to eligible United States-based BlackRock employees may be voluntarily deferred at their election for defined periods of time into an account that tracks the performance of certain of the firm's investment products.

Other Compensation Benefits. In addition to base salary and discretionary incentive compensation, portfolio managers may be eligible to receive or participate in one or more of the following:

Incentive Savings Plans — BlackRock, Inc. has created a variety of incentive savings plans in which BlackRock, Inc. employees are eligible to participate, including a 401(k) plan, the BlackRock Retirement Savings Plan (RSP), and the BlackRock Employee Stock Purchase Plan (ESPP). The employer contribution components of the RSP include a company match equal to 50% of the first 8% of eligible pay contributed to the plan capped at $5,000 per year, and a company retirement contribution equal to 3-5% of eligible compensation up to the Internal Revenue Service limit ($260,000 for 2014). The RSP offers a range of investment options, including registered investment companies and collective investment funds managed by the firm. BlackRock, Inc. contributions follow the investment direction set by participants for their own contributions or, absent participant investment direction, are invested into a target date fund that corresponds to, or is closest to, the year in which the participant attains age 65. The ESPP allows for investment in BlackRock, Inc. common stock at a 5% discount on the fair market value of the stock on the purchase date. Annual participation in the ESPP is limited to the purchase of 1,000 shares of common stock or a dollar value of $25,000 based on its fair market value on the purchase date.

Item 22. Brokerage Allocation and Other Practices

Transactions in Portfolio Securities

Subject to policies established by the Board, BlackRock is primarily responsible for the execution of the Fund's portfolio transactions and the allocation of brokerage. BlackRock does not execute transactions through any particular broker or dealer, but seeks to obtain the best net results for the Fund, taking into account such factors as

II-119

price (including the applicable brokerage commission or dealer spread), size of order, difficulty of execution, operational facilities of the firm and the firm's risk and skill in positioning blocks of securities. While BlackRock generally seeks reasonable trade execution costs, the Fund does not necessarily pay the lowest spread or commission available, and payment of the lowest commission or spread is not necessarily consistent with obtaining the best price and execution in particular transactions. Subject to applicable legal requirements, BlackRock may select a broker based partly upon brokerage or research services provided to BlackRock and its clients, including the Fund. In return for such services, BlackRock may cause the Fund to pay a higher commission than other brokers would charge if BlackRock determines in good faith that the commission is reasonable in relation to the services provided.

In selecting brokers or dealers to execute portfolio transactions, the Investment Advisor seeks to obtain the best price and most favorable execution for the Fund, taking into account a variety of factors including: (i) the size, nature and character of the security or instrument being traded and the markets in which it is purchased or sold; (ii) the desired timing of the transaction; (iii) BlackRock's knowledge of the expected commission rates and spreads currently available; (iv) the activity existing and expected in the market for the particular security or instrument, including any anticipated execution difficulties; (v) the full range of brokerage services provided; (vi) the broker's or dealer's capital; (vii) the quality of research and research services provided; (viii) the reasonableness of the commission, dealer spread or its equivalent for the specific transaction; and (ix) BlackRock's knowledge of any actual or apparent operational problems of a broker or dealer.

Section 28(e) of the Exchange Act ("Section 28(e)") permits an investment adviser, under certain circumstances, to cause an account to pay a broker or dealer a commission for effecting a transaction that exceeds the amount another broker or dealer would have charged for effecting the same transaction in recognition of the value of brokerage and research services provided by that broker or dealer. This includes commissions paid on riskless principal transactions under certain conditions. Brokerage and research services include: (1) furnishing advice as to the value of securities, including pricing and appraisal advice, credit analysis, risk measurement analysis, performance and other analysis, as well as the advisability of investing in, purchasing or selling securities, and the availability of securities or purchasers or sellers of securities; (2) furnishing analyses and reports concerning issuers, industries, securities, economic factors and trends, portfolio strategy, and the performance of accounts; and (3) effecting securities transactions and performing functions incidental to securities transactions (such as clearance, settlement, and custody). BlackRock believes that access to independent investment research is beneficial to its investment decision-making processes and, therefore, to the Fund.

BlackRock may participate in client commission arrangements under which BlackRock may execute transactions through a broker-dealer and request that the broker-dealer allocate a portion of the commissions or commission credits to another firm that provides research to BlackRock. BlackRock believes that research services obtained through soft dollar or commission sharing arrangements enhance its investment decision-making capabilities, thereby increasing the prospects for higher investment returns. BlackRock will engage only in soft dollar or commission sharing transactions that comply with the requirements of Section 28(e). BlackRock regularly evaluates the soft dollar products and services utilized, as well as the overall soft dollar and commission sharing arrangements to ensure that trades are executed by firms that are regarded as best able to execute trades for client accounts, while at the same time providing access to the research and other services BlackRock views as impactful to its trading results.

BlackRock may utilize soft dollars and related services, including research (whether prepared by the broker-dealer or prepared by a third-party and provided to BlackRock by the broker-dealer) and execution or brokerage services within applicable rules and BlackRock's policies to the extent that such permitted services do not compromise BlackRock's ability to seek to obtain best execution. In this regard, the portfolio management investment and/or trading teams may consider a variety of factors, including the degree to which the broker-dealer: (a) provides access to company management; (b) provides access to their analysts; (c) provides meaningful/insightful research notes on companies or other potential investments; (d) facilitates calls on which meaningful or insightful ideas about companies or potential investments are discussed; (e) facilitates conferences at which meaningful or insightful ideas about companies or potential investments are discussed; or (f) provides research tools such as market data, financial analysis, and other third party related research and brokerage tools that aid in the investment process.

Research-oriented services for which BlackRock might pay with Fund commissions may be in written form or through direct contact with individuals and may include information as to particular companies or industries and

II-120

securities or groups of securities, as well as market, economic, or institutional advice and statistical information, political developments and technical market information that assists in the valuation of investments. Except as noted immediately below, research services furnished by brokers may be used in servicing some or all client accounts and not all services may be used in connection with the Fund or account that paid commissions to the broker providing such services. In some cases, research information received from brokers by investment company management personnel, or personnel principally responsible for BlackRock's individually managed portfolios, is not necessarily shared by and between such personnel. Any investment advisory or other fees paid by the Fund to BlackRock are not reduced as a result of BlackRock's receipt of research services. In some cases, BlackRock may receive a service from a broker that has both a "research" and a "non-research" use. When this occurs BlackRock makes a good faith allocation, under all the circumstances, between the research and non-research uses of the service. The percentage of the service that is used for research purposes may be paid for with client commissions, while BlackRock will use its own funds to pay for the percentage of the service that is used for non-research purposes. In making this good faith allocation, BlackRock faces a potential conflict of interest, but BlackRock believes that its allocation procedures are reasonably designed to ensure that it appropriately allocates the anticipated use of such services to their research and non-research uses.

Payments of commissions to brokers who are affiliated persons of the Fund will be made in accordance with Rule 17e-1 under the 1940 Act.

From time to time, the Fund may purchase new issues of securities in a fixed price offering. In these situations, the broker may be a member of the selling group that will, in addition to selling securities, provide BlackRock with research services. The Financial Industry Regulatory Authority, Inc. has adopted rules expressly permitting these types of arrangements under certain circumstances. Generally, the broker will provide research "credits" in these situations at a rate that is higher than that available for typical secondary market transactions. These arrangements may not fall within the safe harbor of Section 28(e).

BlackRock does not consider sales of shares of the investment companies it advises as a factor in the selection of brokers or dealers to execute portfolio transactions for the Fund; however, whether or not a particular broker or dealer sells shares of the investment companies advised by BlackRock neither qualifies nor disqualifies such broker or dealer to execute transactions for those investment companies.

The Fund anticipates that its brokerage transactions involving foreign securities generally will be conducted primarily on the principal stock exchanges of the applicable country. Foreign equity securities may be held by the Fund in the form of depositary receipts, or other securities convertible into foreign equity securities. Depositary receipts may be listed on stock exchanges, or traded in over-the-counter markets in the United States or Europe, as the case may be. American Depositary Receipts, like other securities traded in the United States, will be subject to negotiated commission rates.

The Fund may invest in certain securities traded in the OTC market and intends to deal directly with the dealers who make a market in the particular securities, except in those circumstances in which better prices and execution are available elsewhere. Under the 1940 Act, persons affiliated with the Fund and persons who are affiliated with such affiliated persons are prohibited from dealing with the Fund as principal in the purchase and sale of securities unless a permissive order allowing such transactions is obtained from the SEC. Since transactions in the OTC market usually involve transactions with the dealers acting as principal for their own accounts, the Fund will not deal with affiliated persons, including PNC and its affiliates, in connection with such transactions. However, an affiliated person of the Fund may serve as its broker in OTC transactions conducted on an agency basis provided that, among other things, the fee or commission received by such affiliated broker is reasonable and fair compared to the fee or commission received by non-affiliated brokers in connection with comparable transactions. In addition, the Fund may not purchase securities during the existence of any underwriting syndicate for such securities of which PNC is a member or in a private placement in which PNC serves as placement agent except pursuant to procedures approved by the Board that either comply with rules adopted by the SEC or with interpretations of the SEC staff.

Over-the-counter issues, including most fixed income securities such as corporate debt and U.S. Government securities, are normally traded on a "net" basis without a stated commission, through dealers acting for their own account and not as brokers. The Fund will primarily engage in transactions with these dealers or deal directly with the issuer unless a better price or execution could be obtained by using a broker. Prices paid to a dealer with respect to both foreign and domestic securities will generally include a "spread," which is the difference

II-121

between the prices at which the dealer is willing to purchase and sell the specific security at the time, and includes the dealer's normal profit.

Purchases of money market instruments by the Fund are made from dealers, underwriters and issuers. The Fund does not currently expect to incur any brokerage commission expense on such transactions because money market instruments are generally traded on a "net" basis with dealers acting as principal for their own accounts without a stated commission. The price of the security, however, usually includes a profit to the dealer.

Securities purchased in underwritten offerings include a fixed amount of compensation to the underwriter, generally referred to as the underwriter's concession or discount. When securities are purchased or sold directly from or to an issuer, no commissions or discounts are paid.

The Investment Advisor may seek to obtain an undertaking from issuers of commercial paper or dealers selling commercial paper to consider the repurchase of such securities from the Fund prior to maturity at their original cost plus interest (sometimes adjusted to reflect the actual maturity of the securities), if it believes that the Fund's anticipated need for liquidity makes such action desirable. Any such repurchase prior to maturity reduces the possibility that the Fund would incur a capital loss in liquidating commercial paper, especially if interest rates have risen since acquisition of such commercial paper.

Investment decisions for the Fund and for other investment accounts managed by the Investment Advisor are made independently of each other in light of differing conditions. BlackRock allocates investments among client accounts in a fair and equitable manner. A variety of factors will be considered in making such allocations. These factors include: (i) investment objectives or strategies for particular accounts, including sector, industry, country or region and capitalization weightings, (ii) tax considerations of an account, (iii) risk or investment concentration parameters for an account, (iv) supply or demand for a security at a given price level, (v) size of available investment, (vi) cash availability and liquidity requirements for accounts, (vii) regulatory restrictions, (viii) minimum investment size of an account, (ix) relative size of account, and (x) such other factors as may be approved by BlackRock's general counsel. Moreover, investments may not be allocated to one client account over another based on any of the following considerations: (i) to favor one client account at the expense of another, (ii) to generate higher fees paid by one client account over another or to produce greater performance compensation to BlackRock, (iii) to develop or enhance a relationship with a client or prospective client, (iv) to compensate a client for past services or benefits rendered to BlackRock or to induce future services or benefits to be rendered to BlackRock, or (v) to manage or equalize investment performance among different client accounts.

Equity securities will generally be allocated among client accounts within the same investment mandate on a pro rata basis. This pro-rata allocation may result in the Fund receiving less of a particular security than if pro-ration had not occurred. All allocations of equity securities will be subject, where relevant, to share minimums established for accounts and compliance constraints.

Initial public offerings of securities may be over-subscribed and subsequently trade at a premium in the secondary market. When BlackRock is given an opportunity to invest in such an initial offering or "new" or "hot" issue, the supply of securities available for client accounts is often less than the amount of securities the accounts would otherwise take. In order to allocate these investments fairly and equitably among client accounts over time, each portfolio manager or a member of his or her respective investment team will indicate to BlackRock's trading desk their level of interest in a particular offering with respect to eligible clients' accounts for which that team is responsible. Initial public offerings of U.S. equity securities will be identified as eligible for particular client accounts that are managed by portfolio teams who have indicated interest in the offering based on market capitalization of the issuer of the security and the investment mandate of the client account and in the case of international equity securities, the country where the offering is taking place and the investment mandate of the client account. Generally, shares received during the initial public offering will be allocated among participating client accounts within each investment mandate on a pro rata basis. In situations where supply is too limited to be allocated among all accounts for which the investment is eligible, portfolio managers may rotate such investment opportunities among one or more accounts so long as the rotation system provides for fair access for all client accounts over time. Other allocation methodologies that are considered by BlackRock to be fair and equitable to clients may be used as well.

II-122

Because different accounts may have differing investment objectives and policies, BlackRock may buy and sell the same securities at the same time for different clients based on the particular investment objective, guidelines and strategies of those accounts. For example, BlackRock may decide that it may be entirely appropriate for a growth fund to sell a security at the same time a value fund is buying that security. To the extent that transactions on behalf of more than one client of BlackRock or its affiliates during the same period may increase the demand for securities being purchased or the supply of securities being sold, there may be an adverse effect on price. For example, sales of a security by BlackRock on behalf of one or more of its clients may decrease the market price of such security, adversely impacting other BlackRock clients that still hold the security. If purchases or sales of securities arise for consideration at or about the same time that would involve the Fund or other clients or funds for which BlackRock or an affiliate act as investment manager, transactions in such securities will be made, insofar as feasible, for the respective funds and clients in a manner deemed equitable to all.

In certain instances, BlackRock may find it efficient for purposes of seeking to obtain best execution, to aggregate or "bunch" certain contemporaneous purchases or sale orders of its advisory accounts. In general, all contemporaneous trades for client accounts under management by the same portfolio manager or investment team will be bunched in a single order if the trader believes the bunched trade would provide each client with an opportunity to achieve a more favorable execution at a potentially lower execution cost. The costs associated with a bunched order will be shared pro rata among the clients in the bunched order. Generally, if an order for a particular portfolio manager or management team is filled at several different prices through multiple trades, all accounts participating in the order will receive the average price except in the case of certain international markets where average pricing is not permitted. While in some cases this practice could have a detrimental effect upon the price or value of the security as far as the Fund is concerned, in other cases it could be beneficial to the Fund. Transactions effected by BlackRock on behalf of more than one of its clients during the same period may increase the demand for securities being purchased or the supply of securities being sold, causing an adverse effect on price. The trader will give the bunched order to the broker dealer that the trader has identified as being able to provide the best execution of the order. Orders for purchase or sale of securities will be placed within a reasonable amount of time of the order receipt and bunched orders will be kept bunched only long enough to execute the order.

The Fund will not purchase securities during the existence of any underwriting or selling group relating to such securities of which BlackRock, PNC, the Distributor or any affiliated person (as defined in the 1940 Act) thereof is a member except pursuant to procedures adopted by the Board in accordance with Rule 10f-3 under the 1940 Act. In no instance will portfolio securities be purchased from or sold to BlackRock, PNC, the Distributor or any affiliated person of the foregoing entities except as permitted by SEC exemptive order or by applicable law.

Portfolio Turnover

While the Fund generally does not expect to engage in trading for short term gains, it will effect portfolio transactions without regard to any holding period if, in Fund management's judgment, such transactions are advisable in light of a change in circumstances of a particular company or within a particular industry or in general market, economic or financial conditions. The portfolio turnover rate is calculated by dividing the lesser of the Fund's annual sales or purchases of portfolio securities (exclusive of purchases or sales of U.S. government securities and all other securities whose maturities at the time of acquisition were one year or less) by the monthly average value of the securities in the portfolio during the year. A high rate of portfolio turnover results in certain tax consequences, such as increased capital gain dividends and/or ordinary income dividends, and in correspondingly greater transaction costs in the form of dealer spreads and brokerage commissions, which are borne directly by the Fund.

Privacy Principles of the Fund

The Fund is committed to maintaining the privacy of its current and former shareholders and to safeguarding their non-public personal information. The following information is provided to help you understand what personal information the Fund collects, how the Fund protects that information and why, in certain cases, the Fund may share such information with select parties.

Item 30. Indemnification

Article V of the Fund's Agreement and Declaration of Trust provides as follows:

5.1 No Personal Liability of Shareholders, Trustees, etc. No Shareholder of the Trust shall be subject in such capacity to any personal liability whatsoever to any Person in connection with Trust Property or the acts, obligations or affairs of the Trust. Shareholders shall have the same limitation of personal liability as is extended to stockholders of a private corporation for profit incorporated under the Delaware General Corporation Law. No Trustee or officer of the Trust shall be subject in such capacity to any personal liability whatsoever to any Person, save only liability to the Trust or its Shareholders arising from bad faith, willful misfeasance, gross negligence or reckless disregard for his duty to such Person; and, subject to the foregoing exception, all such Persons shall look solely to the Trust Property for satisfaction of claims of any nature arising in connection with the affairs of the Trust. If any Shareholder, Trustee or officer, as such, of the Trust, is made a party to any suit or proceeding to enforce any such liability, subject to the foregoing exception, he shall not, on account thereof, be held to any personal liability. Any repeal or modification of this Section 5.1 shall not adversely affect any right or protection of a Trustee or officer of the Trust existing at the time of such repeal or modification with respect to acts or omissions occurring prior to such repeal or modification.

5.2 Mandatory Indemnification.

(a) The Trust hereby agrees to indemnify each person who at any time serves as a Trustee or officer of the Trust (each such person being an "indemnitee") against any liabilities and expenses, including amounts paid in satisfaction of judgments, in compromise or as fines and penalties, and reasonable counsel fees reasonably incurred by such indemnitee in connection with the defense or disposition of any action, suit or other proceeding, whether civil or criminal, before any court or administrative or investigative body in which he may be or may have been involved as a party or otherwise or with which he may be or may have been threatened, while acting in any

II-124

capacity set forth in this Article V by reason of his having acted in any such capacity, except with respect to any matter as to which he shall not have acted in good faith in the reasonable belief that his action was in the best interest of the Trust or, in the case of any criminal proceeding, as to which he shall have had reasonable cause to believe that the conduct was unlawful, provided, however, that no indemnitee shall be indemnified hereunder against any liability to any person or any expense of such indemnitee arising by reason of (i) willful misfeasance, (ii) bad faith, (iii) gross negligence, or (iv) reckless disregard of the duties involved in the conduct of his position (the conduct referred to in such clauses (i) through (iv) being sometimes referred to herein as "disabling conduct"). Notwithstanding the foregoing, with respect to any action, suit or other proceeding voluntarily prosecuted by any indemnitee as plaintiff, indemnification shall be mandatory only if the prosecution of such action, suit or other proceeding by such indemnitee (1) was authorized by a majority of the Trustees or (2) was instituted by the indemnitee to enforce his or her rights to indemnification hereunder in a case in which the indemnitee is found to be entitled to such indemnification. The rights to indemnification set forth in this Declaration shall continue as to a person who has ceased to be a Trustee or officer of the Trust and shall inure to the benefit of his or her heirs, executors and personal and legal representatives. No amendment or restatement of this Declaration or repeal of any of its provisions shall limit or eliminate any of the benefits provided to any person who at any time is or was a Trustee or officer of the Trust or otherwise entitled to indemnification hereunder in respect of any act or omission that occurred prior to such amendment, restatement or repeal.

(b) Notwithstanding the foregoing, no indemnification shall be made hereunder unless there has been a determination (i) by a final decision on the merits by a court or other body of competent jurisdiction before whom the issue of entitlement to indemnification hereunder was brought that such indemnitee is entitled to indemnification hereunder or, (ii) in the absence of such a decision, by (1) a majority vote of a quorum of those Trustees who are neither "interested persons" of the Trust (as defined in Section 2(a)(19) of the 1940 Act) nor parties to the proceeding ("Disinterested Non-Party Trustees"), that the indemnitee is entitled to indemnification hereunder, or (2) if such quorum is not obtainable or even if obtainable, if such majority so directs, independent legal counsel in a written opinion concludes that the Indemnitee should be entitled to indemnification hereunder. All determinations to make advance payments in connection with the expense of defending any proceeding shall be authorized and made in accordance with the immediately succeeding paragraph (c) below.

(c) The Trust shall make advance payments in connection with the expenses of defending any action with respect to which indemnification might be sought hereunder if the Trust receives a written affirmation by the indemnitee of the indemnitee's good faith belief that the standards of conduct necessary for indemnification have been met and a written undertaking to reimburse the Trust unless it is subsequently determined that the indemnitee is entitled to such indemnification and if a majority of the Trustees determine that the applicable standards of conduct necessary for indemnification appear to have been met. In addition, at least one of the following conditions must be met: (i) the indemnitee shall provide adequate security for his undertaking, (ii) the Trust shall be insured against losses arising by reason of any lawful advances, or (iii) a majority of a quorum of the Disinterested Non-Party Trustees, or if a majority vote of such quorum so direct, independent legal counsel in a written opinion, shall conclude, based on a review of readily available facts (as opposed to a full trial-type inquiry), that there is substantial reason to believe that the indemnitee ultimately will be found entitled to indemnification.

(d) The rights accruing to any indemnitee under these provisions shall not exclude any other right which any person may have or hereafter acquire under this Declaration, the By-Laws of the Trust, any statute, agreement, vote of stockholders or Trustees who are "disinterested persons" (as defined in Section 2(a)(19) of the 1940 Act) or any other right to which he or she may be lawfully entitled.

(e) Subject to any limitations provided by the 1940 Act and this Declaration, the Trust shall have the power and authority to indemnify and provide for the advance payment of expenses to employees, agents and other Persons providing services to the Trust or serving in any capacity at the request of the Trust to the full extent corporations organized under the Delaware General

II-125

Corporation Law may indemnify or provide for the advance payment of expenses for such Persons, provided that such indemnification has been approved by a majority of the Trustees.

5.3 No Bond Required of Trustees. No Trustee shall, as such, be obligated to give any bond or other security for the performance of any of his duties hereunder.

5.4 No Duty of Investigation; Notice in Trust Instruments, etc. No purchaser, lender, transfer agent or other person dealing with the Trustees or with any officer, employee or agent of the Trust shall be bound to make any inquiry concerning the validity of any transaction purporting to be made by the Trustees or by said officer, employee or agent or be liable for the application of money or property paid, loaned, or delivered to or on the order of the Trustees or of said officer, employee or agent. Every obligation, contract, undertaking, instrument, certificate, Share, other security of the Trust, and every other act or thing whatsoever executed in connection with the Trust shall be conclusively taken to have been executed or done by the executors thereof only in their capacity as Trustees under this Declaration or in their capacity as officers, employees or agents of the Trust. The Trustees may maintain insurance for the protection of the Trust Property, its Shareholders, Trustees, officers, employees and agents in such amount as the Trustees shall deem adequate to cover possible tort liability, and such other insurance as the Trustees in their sole judgment shall deem advisable or is required by the 1940 Act.

5.5 Reliance on Experts, etc. Each Trustee and officer or employee of the Trust shall, in the performance of its duties, be fully and completely justified and protected with regard to any act or any failure to act resulting from reliance in good faith upon the books of account or other records of the Trust, upon an opinion of counsel, or upon reports made to the Trust by any of the Trust's officers or employees or by any advisor, administrator, manager, distributor, selected dealer, accountant, appraiser or other expert or consultant selected with reasonable care by the Trustees, officers or employees of the Trust, regardless of whether such counsel or expert may also be a Trustee.

Registrant has also entered into an agreement with Trustees and officers of the Registrant entitled to indemnification under the Agreement and Declaration of Trust of the Fund pursuant to which the Registrant has agreed to advance expenses and costs incurred by the indemnitee in connection with any matter in respect of which indemnification might be sought pursuant to the Agreement and Declaration of Trust of the Fund to the maximum extent permitted by law.

Reference is also made to:

Sections 10 and 11 of the Registrant's Investment Management Agreement

Section 8 of the Registrant's Distribution Agreement with the Distributor

Additionally, the Registrant and the other funds in the BlackRock Closed-End Fund Complex jointly maintain, at their own expense, E&O/D&O insurance policies for the benefit of its Trustees, officers and certain affiliated persons. The Registrant pays a pro rata portion of the premium on such insurance policies.

Insofar as indemnification for liabilities arising under the Securities Act, may be permitted to Trustees, officers and controlling persons of the Fund, pursuant to the foregoing provisions or otherwise, the Fund has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a Trustee, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such Trustee, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

Not applicable.

The Registrant undertakes:

to file, during any period in which offers or sales are being made, a post-effective amendment to the Registration Statement (1) to include any prospectus required by Section 10(a)(3) of the 1933 Act; (2) to reflect in the prospectus any facts or events after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement; (3) and to include any material information with respect to any plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement;

that for the purpose of determining any liability under the 1933 Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of those securities at that time shall be deemed to be the initial bona fide offering thereof;

APPENDIX A

RATINGS OF INVESTMENTS

Standard & Poor's Corporation—A brief description of the applicable Standard & Poor's Corporation ("S&P") rating symbols and their meanings (as published by S&P) follows:

A S&P issue credit rating is a forward-looking opinion about the creditworthiness of an obligor with respect to a specific financial obligation, a specific class of financial obligations or a specific financial program (including ratings on medium-term note programs and commercial paper programs). It takes into consideration the creditworthiness of guarantors, insurers or other forms of credit enhancement on the obligation and takes into account the currency in which the obligation is denominated. The opinion reflects S&P's view of the obligor's capacity and willingness to meet its financial commitments as they come due, and may assess terms, such as collateral security and subordination, which could affect ultimate payment in the event of default.

Issue credit ratings can be either long-term or short-term. Short-term ratings are generally assigned to those obligations considered short-term in the relevant market. In the U.S., for example, that means obligations with an original maturity of no more than 365 days – including commercial paper. Short-term ratings are also used to indicate the creditworthiness of an obligor with respect to put features on long-term obligations. The result is a dual rating, in which the short-term rating addresses the put feature, in addition to the usual long-term rating. Medium-term notes are assigned long-term ratings.

Long-Term Issue Credit Ratings

Issue credit ratings are based, in varying degrees, on S&P's analysis of the following considerations:

likelihood of payment – capacity and willingness of the obligor to meet its financial commitment on an obligation in accordance with the terms of the obligation;

nature of and provisions of the obligation; and

protection afforded by, and relative position of, the obligation in the event of bankruptcy, reorganization, or other arrangement under the laws of bankruptcy and other laws affecting creditors' rights.

Issue ratings are an assessment of default risk, but may incorporate an assessment of relative seniority or ultimate recovery in the event of default. Junior obligations are typically rated lower than senior obligations, to reflect the lower priority in bankruptcy, as noted above. (Such differentiation may apply when an entity has both senior and subordinated obligations, secured and unsecured obligations, or operating company and holding company obligations.)

AAA

An obligation rated "AAA" has the highest rating assigned by S&P. The obligor's capacity to meet its financial commitment on the obligation is extremely strong.

An obligation rated "AA" differs from the highest-rated obligations only to a small degree. The obligor's capacity to meet its financial commitment on the obligation is very strong.

An obligation rated "A" is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rated categories. However, the obligor's capacity to meet its financial commitment on the obligation is still strong.

A-1

BBB

An obligation rated "BBB" exhibits adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity of the obligor to meet its financial commitment on the obligation.

Obligations rated "BB," "B," "CCC," "CC" and "C" are regarded as having significant speculative characteristics. "BB" indicates the least degree of speculation and "C" the highest. While such obligations will likely have some quality and protective characteristics, these may be outweighed by large uncertainties or major exposures to adverse conditions.

An obligation rated "BB" is less vulnerable to nonpayment than other speculative issues. However, it faces major ongoing uncertainties or exposure to adverse business, financial or economic conditions which could lead to the obligor's inadequate capacity to meet its financial commitment on the obligation.

An obligation rated "B" is more vulnerable to nonpayment than obligations rated "BB," but the obligor currently has the capacity to meet its financial commitment on the obligation. Adverse business, financial or economic conditions will likely impair the obligor's capacity or willingness to meet its financial commitment on the obligation.

CCC

An obligation rated "CCC" is currently vulnerable to nonpayment and is dependent upon favorable business, financial and economic conditions for the obligor to meet its financial commitment on the obligation. In the event of adverse business, financial or economic conditions, the obligor is not likely to have the capacity to meet its financial commitment on the obligation.

An obligation rated "CC" is currently highly vulnerable to nonpayment.

A "C" rating is assigned to obligations that are currently highly vulnerable to nonpayment, obligations that have payment arrearages allowed by the terms of the documents or obligations of an issuer that is the subject of a bankruptcy petition or similar action which have not experienced a payment default. Among others, the "C" rating may be assigned to subordinated debt, preferred stock or other obligations on which cash payments have been suspended in accordance with the instrument's terms or when preferred stock is the subject of a distressed exchange offer, whereby some or all of the issue is either repurchased for an amount of cash or replaced by other instruments having a total value that is less than par.

An obligation rated "D" is in payment default. The "D" rating category is used when payments on an obligation, including a regulatory capital instrument, are not made on the date due even if the applicable grace period has not expired, unless S&P believes that such payments will be made during such grace period. The "D" rating also will be used upon the filing of a bankruptcy petition or the taking of similar action if payments on an obligation are jeopardized. An obligation's rating is lowered to "D" upon completion of a distressed exchange offer, whereby some or all of the issue is either repurchased for an amount of cash or replaced by other instruments having a total value that is less than par.

This indicates that no rating has been requested, that there is insufficient information on which to base a rating or that S&P does not rate a particular obligation as a matter of policy.

The ratings from "AA" to "CCC" may be modified by the addition of a plus (+) or minus (-) sign to show relative standing within the major rating categories.

A-2

Short-Term Issue Credit Ratings

A-1

A short-term obligation rated "A-1" is rated in the highest category by S&P. The obligor's capacity to meet its financial commitment on the obligation is strong. Within this category, certain obligations are designated with a plus sign (+). This indicates that the obligor's capacity to meet its financial commitment on these obligations is extremely strong.

A-2

A short-term obligation rated "A-2" is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rating categories. However, the obligor's capacity to meet its financial commitment on the obligation is satisfactory.

A-3

A short-term obligation rated "A-3" exhibits adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity of the obligor to meet its financial commitment on the obligation.

A short-term obligation rated "B" is regarded as having significant speculative characteristics. Ratings of "B-1," "B-2" and "B-3" may be assigned to indicate finer distinctions within the "B" category. The obligor currently has the capacity to meet its financial commitment on the obligation; however, it faces major ongoing uncertainties which could lead to the obligor's inadequate capacity to meet its financial commitment on the obligation.

B-1

A short-term obligation rated "B-1" is regarded as having significant speculative characteristics, but the obligor has a relatively stronger capacity to meet its financial commitments over the short-term compared to other speculative-grade obligors.

B-2

A short-term obligation rated "B-2" is regarded as having significant speculative characteristics and the obligor has an average speculative-grade capacity to meet its financial commitments over the short-term compared to other speculative-grade obligors.

B-3

A short-term obligation rated "B-3" is regarded as having significant speculative characteristics and the obligor has a relatively weaker capacity to meet its financial commitments over the short-term compared to other speculative-grade obligors.

A short-term obligation rated "C" is currently vulnerable to nonpayment and is dependent upon favorable business, financial and economic conditions for the obligor to meet its financial commitment on the obligation.

A short-term obligation rated "D" is in payment default. The "D" rating category is used when payments on an obligation, including a regulatory capital instrument, are not made on the date due even if the applicable grace period has not expired, unless S&P believes that such payments will be made during such grace period. The "D" rating also will be used upon the filing of a bankruptcy petition or the taking of a similar action if payments on an obligation are jeopardized.

Active Qualifiers (Currently applied and/or outstanding)

This subscript is used for issues in which the credit factors, terms, or both, that determine the likelihood of receipt of payment of interest are different from the credit factors, terms or both that determine the likelihood of receipt of principal on the obligation. The "i" subscript indicates that the rating addresses the interest portion of the obligation only. The "i" subscript will always be used in conjunction with the "p" subscript, which addresses likelihood of receipt of principal. For example, a rated obligation could be

A-3

assigned ratings of "AAAp NRi" indicating that the principal portion is rated "AAA" and the interest portion of the obligation is not rated.

Ratings qualified with "L" apply only to amounts invested up to federal deposit insurance limits.

This subscript is used for issues in which the credit factors, the terms, or both, that determine the likelihood of receipt of payment of principal are different from the credit factors, terms or both that determine the likelihood of receipt of interest on the obligation. The "p" subscript indicates that the rating addresses the principal portion of the obligation only. The "p" subscript will always be used in conjunction with the "i" subscript, which addresses likelihood of receipt of interest. For example, a rated obligation could be assigned ratings of "AAAp NRi" indicating that the principal portion is rated "AAA" and the interest portion of the obligation is not rated.

Ratings with a "pi" subscript are based on an analysis of an issuer's published financial information, as well as additional information in the public domain. They do not, however, reflect in-depth meetings with an issuer's management and therefore may be based on less comprehensive information than ratings without a "pi" subscript. Ratings with a "pi" subscript are reviewed annually based on a new year's financial statements, but may be reviewed on an interim basis if a major event occurs that may affect the issuer's credit quality.

prelim

Preliminary ratings, with the "prelim" qualifier, may be assigned to obligors or obligations, including financial programs, in the circumstances described below. Assignment of a final rating is conditional on the receipt by S&P of appropriate documentation. S&P reserves the right not to issue a final rating. Moreover, if a final rating is issued, it may differ from the preliminary rating.

Preliminary ratings may be assigned to obligations, most commonly structured and project finance issues, pending receipt of final documentation and legal opinions.

Preliminary ratings are assigned to Rule 415 Shelf Registrations. As specific issues, with defined terms, are offered from the master registration, a final rating may be assigned to them in accordance with S&P policies.

Preliminary ratings may be assigned to obligations that will likely be issued upon the obligor's emergence from bankruptcy or similar reorganization, based on late-stage reorganization plans, documentation and discussions with the obligor. Preliminary ratings may also be assigned to the obligors. These ratings consider the anticipated general credit quality of the reorganized or post-bankruptcy issuer as well as attributes of the anticipated obligation(s).

Preliminary ratings may be assigned to entities that are being formed or that are in the process of being independently established when, in S&P's opinion, documentation is close to final. Preliminary ratings may also be assigned to these entities' obligations.

Preliminary ratings may be assigned when a previously unrated entity is undergoing a well-formulated restructuring, recapitalization, significant financing or other transformative event, generally at the point that investor or lender commitments are invited. The preliminary rating may be assigned to the entity and to its proposed obligation(s). These preliminary ratings consider the anticipated general credit quality of the obligor, as well as attributes of the anticipated obligation(s), assuming successful completion of the transformative event. Should the transformative event not occur, S&P would likely withdraw these preliminary ratings.

A-4

A preliminary recovery rating may be assigned to an obligation that has a preliminary issue credit rating.

This symbol indicates termination structures that are designed to honor their contracts to full maturity or, should certain events occur, to terminate and cash settle all their contracts before their final maturity date.

uns(…)

Unsolicited ratings are those credit ratings assigned at the initiative of S&P and not at the request of the issuer or its agents.

Municipal Short-Term Note Ratings Definitions

A S&P U.S. municipal note rating reflects S&P's opinion about the liquidity factors and market access risks unique to the notes. Notes due in three years or less will likely receive a note rating. Notes with an original maturity of more than three years will most likely receive a long-term debt rating. In determining which type of rating, if any, to assign, S&P's analysis will review the following considerations:

Amortization schedule – the larger the final maturity relative to other maturities, the more likely it will be treated as a note; and

Source of payment – the more dependent the issue is on the market for its refinancing, the more likely it will be treated as a note.

Note rating symbols are as follows:

SP-1

Strong capacity to pay principal and interest. An issue determined to possess a very strong capacity to pay debt service is given a plus (+) designation.

SP-2

Satisfactory capacity to pay principal and interest, with some vulnerability to adverse financial and economic changes over the term of the notes.

SP-3

Speculative capacity to pay principal and interest.

Moody's Investors Service, Inc.—A brief description of the applicable Moody's Investors Service, Inc. ("Moody's") rating symbols and their meanings (as published by Moody's) follows:

Long-Term Obligation Ratings

Moody's long-term ratings are opinions of the relative credit risk of financial obligations with an original maturity of one year or more. They address the possibility that a financial obligation will not be honored as promised. Such ratings use Moody's Global Scale and reflect both the likelihood of default and any financial loss suffered in the event of default.

Aaa

Obligations rated "Aaa" are judged to be of the highest quality, with minimal credit risk.

Obligations rated "Aa" are judged to be of high quality and are subject to very low credit risk.

Obligations rated "A" are considered upper-medium grade and are subject to low credit risk.

Baa

Obligations rated "Baa" are subject to moderate credit risk. They are considered medium grade and as such may possess certain speculative characteristics.

Obligations rated "Ba" are judged to have speculative elements and are subject to substantial credit risk.

A-5

Obligations rated "B" are considered speculative and are subject to high credit risk.

Caa

Obligations rated "Caa" are judged to be of poor standing and are subject to very high credit risk.

Obligations rated "Ca" are highly speculative and are likely in, or very near, default, with some prospect of recovery of principal and interest.

Obligations rated "C" are the lowest rated class of bonds and are typically in default, with little prospect for recovery of principal or interest.

Note: Moody's appends numerical modifiers 1, 2 and 3 to each generic rating classification from "Aa" through "Caa." The modifier 1 indicates that the obligation ranks in the higher end of its generic rating category, the modifier 2 indicates a mid-range ranking and the modifier 3 indicates a ranking in the lower end of that generic rating category.

Short-Term Obligation Ratings

Moody's short-term ratings are opinions of the ability of issuers to honor short-term financial obligations. Ratings may be assigned to issuers, short-term programs or to individual short-term debt instruments. Such obligations generally have an original maturity not exceeding thirteen months, unless explicitly noted. Moody's employs the following designations to indicate the relative repayment ability of rated issuers:

P-1

Issuers (or supporting institutions) rated Prime-1 have a superior ability to repay short-term debt obligations.

P-2

Issuers (or supporting institutions) rated Prime-2 have a strong ability to repay short-term debt obligations.

P-3

Issuers (or supporting institutions) rated Prime-3 have an acceptable ability to repay short-term obligations.

Issuers (or supporting institutions) rated Not Prime do not fall within any of the Prime rating categories.

US Municipal Short-Term Obligation Ratings

There are three rating categories for short-term municipal obligations that are considered investment grade. These ratings are designated as Municipal Investment Grade (MIG) and are divided into three levels—MIG 1 through MIG 3. In addition, those short-term obligations that are of speculative quality are designated SG, or speculative grade. MIG ratings expire at the maturity of the obligation.

MIG1

This designation denotes superior credit quality. Excellent protection is afforded by established cash flows, highly reliable liquidity support, or demonstrated broad-based access to the market for refinancing.

MIG2

This designation denotes strong credit quality. Margins of protection are ample, although not as large as in the preceding group.

MIG3

This designation denotes acceptable credit quality. Liquidity and cash-flow protection may be narrow, and market access for refinancing is likely to be less well-established.

This designation denotes speculative-grade credit quality. Debt instruments in this category may lack sufficient margins of protection.

A-6

Other Ratings Symbols

Expected ratings. To address market demand for timely information on particular types of credit ratings, Moody's has licensed to certain third parties the right to generate "Expected Ratings." Expected Ratings are designated by an "e" after the rating code, and are intended to anticipate Moody's forthcoming rating assignments based on reliable information from third-party sources (such as the issuer or underwriter associated with the particular securities) or established Moody's rating practices (i.e., medium term notes are typically, but not always, assigned the same rating as the note's program rating). Expected Ratings will exist only until Moody's confirms the Expected Rating, or issues a different rating for the relevant instrument. Moody's encourages market participants to contact Moody's Ratings Desk or visit www.moodys.com if they have questions regarding Expected Ratings, or wish Moody's to confirm an Expected Rating.

(P)

Provisional Ratings. As a service to the market and at the request of an issuer, Moody's will often assign a provisional rating when the assignment of a final rating is subject to the fulfillment of contingencies but it is highly likely that the rating will become definitive after all documents are received or an obligation is issued into the market. A provisional rating is denoted by placing a (P) in front of the rating. Such ratings are typically assigned to shelf registrations under SEC rule 415 or transaction-based structures that require investor education. When a transaction uses a well-established structure and the transaction's structure and terms are not expected to change prior to sale in a manner that would affect the rating, a definitive rating may be assigned directly.

Refundeds. Issues that are secured by escrowed funds held in trust, reinvested in direct, non-callable US government obligations or non-callable obligations unconditionally guaranteed by the US Government or Resolution Funding Corporation are identified with a # (hatch mark) symbol, (e.g. #Aaa).

Withdrawn. When Moody's no longer rates an obligation on which it previously maintained a rating, the symbol WR is employed. Please see Moody's Guidelines for the Withdrawal of Ratings, available on www.moodys.com.

Not Rated. NR is assigned to an unrated issuer, obligation and/or program.

NAV

Not Available. An issue that Moody's has not yet rated is denoted by the NAV symbol.

TWR

Terminated Without Rating. The symbol TWR applies primarily to issues that mature or are redeemed without having been rated.

A-7

APPENDIX B

PROXY VOTING POLICIES – BLACKROCK U.S. REGISTERED FUNDS

I.	INTRODUCTION

The Trustees/Directors ("Directors") of the BlackRock-Advised Funds (the "Funds") have the responsibility for voting proxies relating to portfolio securities of the Funds, and have determined that it is in the best interests of the Funds and their shareholders to delegate that responsibility to BlackRock Advisors, LLC and its affiliated U.S. registered investment advisers ("BlackRock"), the investment adviser to the Funds, as part of BlackRock's authority to manage, acquire and dispose of account assets. The Directors hereby direct BlackRock to vote such proxies in accordance with this Policy, and any proxy voting guidelines that the Adviser determines are appropriate and in the best interests of the Funds' shareholders and which are consistent with the principles outlined in this Policy. Individual series of the Funds may be specifically excluded from this Policy by the Directors by virtue of the adoption of alternative proxy voting policy for such series. The Directors have authorized BlackRock to utilize unaffiliated third-parties as its agents to vote portfolio proxies in accordance with this Policy and to maintain records of such portfolio proxy voting.

Rule 206(4)-6 under the Investment Advisers Act of 1940 requires, among other things, that an investment adviser that exercises voting authority over clients' proxy voting adopt policies and procedures reasonably designed to ensure that the adviser votes proxies in the best interests of clients, discloses to its clients information about those policies and procedures and also discloses to clients how they may obtain information on how the adviser has voted their proxies.

BlackRock has adopted guidelines and procedures that are consistent with the principles of this Policy. BlackRock's corporate governance committee structure (the "Committee"), oversees the proxy voting function on behalf of BlackRock and its clients, including the Funds. The Committee is comprised of senior members of BlackRock's Portfolio Management and Administration Groups and is advised by BlackRock's Legal and Compliance Department.

BlackRock votes (or refrains from voting) proxies for each Fund in a manner that BlackRock, in the exercise of its independent business judgment, concludes is in the best economic interests of such Fund. In some cases, BlackRock may determine that it is in the best economic interests of a Fund to refrain from exercising the Fund's proxy voting rights (such as, for example, proxies on certain non-U.S. securities that might impose costly or time-consuming in-person voting requirements). With regard to the relationship between securities lending and proxy voting, BlackRock's approach is also driven by our clients' economic interests. The evaluation of the economic desirability of recalling loans involves balancing the revenue producing value of loans against the likely economic value of casting votes. Based on our evaluation of this relationship, BlackRock believes that the likely economic value of casting a vote generally is less than the securities lending income, either because the votes will not have significant economic consequences or because the outcome of the vote would not be affected by BlackRock recalling loaned securities in order to ensure they are voted. Periodically, BlackRock analyzes the process and benefits of voting proxies for securities on loan, and will consider whether any modification of its proxy voting policies or procedures are necessary in light of any regulatory changes.

BlackRock will normally vote on specific proxy issues in accordance with BlackRock's proxy voting guidelines. BlackRock's proxy voting guidelines provide detailed guidance as to how to vote proxies on certain important or commonly raised issues. BlackRock may, in the exercise of its business judgment, conclude that the proxy voting guidelines do not cover the specific matter upon which a proxy vote is requested, or that an exception to the proxy voting guidelines would be in the best economic interests of a Fund. BlackRock votes (or refrains from voting) proxies without regard to the relationship of the issuer of the proxy (or any shareholder of such issuer) to the Fund, the Fund's affiliates (if any), BlackRock or BlackRock's affiliates. When voting proxies, BlackRock attempts to encourage companies to follow practices that enhance shareholder value and increase transparency and allow the market to place a proper value on their assets.

II. PROXY VOTING POLICIES

A. Boards of Directors

The Funds generally support the board's nominees in the election of directors and generally support proposals that strengthen the independence of boards of directors. As a general matter, the Funds believe that a company's board of directors (rather than shareholders) is most likely to have access to important, nonpublic information regarding a company's business and prospects, and is therefore best-positioned to set corporate policy and oversee management. The Funds therefore believe that the foundation of good corporate governance is the election of responsible, qualified, independent corporate directors who are likely to diligently represent the interests of shareholders and oversee management of the corporation in a manner that will

B-1

seek to maximize shareholder value over time. In individual cases, consideration may be given to a director nominee's history of representing shareholder interests as a director of the company issuing the proxy or other companies, or other factors to the extent deemed relevant by the Committee.

B. Auditors

These proposals concern those issues submitted to shareholders related to the selection of auditors. As a general matter, the Funds believe that corporate auditors have a responsibility to represent the interests of shareholders and provide an independent view on the propriety of financial reporting decisions of corporate management. While the Funds anticipate that BlackRock will generally defer to a corporation's choice of auditor, in individual cases, consideration may be given to an auditors' history of representing shareholder interests as auditor of the company issuing the proxy or other companies, to the extent deemed relevant.

C. Compensation and Benefits

These proposals concern those issues submitted to shareholders related to management compensation and employee benefits. As a general matter, the Funds favor disclosure of a company's compensation and benefit policies and oppose excessive compensation, but believe that compensation matters are normally best determined by a corporation's board of directors, rather than shareholders. Proposals to "micro-manage" a company's compensation practices or to set arbitrary restrictions on compensation or benefits should therefore generally not be supported.

D. Capital Structure

These proposals relate to various requests, principally from management, for approval of amendments that would alter the capital structure of a company, such as an increase in authorized shares. As a general matter, the Funds expect that BlackRock will support requests that it believes enhance the rights of common shareholders and oppose requests that appear to be unreasonably dilutive.

E. Corporate Charter and By-Laws

These proposals relate to various requests for approval of amendments to a corporation's charter or by-laws. As a general matter, the Funds generally vote against anti-takeover proposals and proposals that would create additional barriers or costs to corporate transactions that are likely to deliver a premium to shareholders.

F. Environmental and Social Issues

These are shareholder proposals addressing either corporate social and environmental policies or requesting specific reporting on these issues. The Funds generally do not support proposals on social issues that lack a demonstrable economic benefit to the issuer and the Fund investing in such issuer. BlackRock seeks to make proxy voting decisions in the manner most likely to protect and promote the long-term economic value of the securities held in client accounts. We intend to support economically advantageous corporate practices while leaving direct oversight of company management and strategy to boards of directors. We seek to avoid micromanagement of companies, as we believe that a company's board of directors is best positioned to represent shareholders and oversee management on shareholders behalf. Issues of corporate social and environmental responsibility are evaluated on a case-by-case basis within this framework.

III. CONFLICTS MANAGEMENT

BlackRock maintains policies and procedures that are designed to prevent any relationship between the issuer of the proxy (or any shareholder of the issuer) and a Fund, a Fund's affiliates (if any), BlackRock or BlackRock's affiliates, from having undue influence on BlackRock's proxy voting activity. In certain instances, BlackRock may determine to engage an independent fiduciary to vote proxies as a further safeguard against potential conflicts of interest or as otherwise required by applicable law. The independent fiduciary may either vote such proxies or provide BlackRock with instructions as to how to vote such proxies. In the latter case, BlackRock votes the proxy in accordance with the independent fiduciary's determination.

IV. REPORTS TO THE BOARD

BlackRock will report to the Directors on proxy votes it has made on behalf of the Funds at least annually.
