The principal amount for such securities is shown in the respective foreign currency. The date shown on options represents the expiration date of the option contract. The option contract may be exercised at any date on or before the date shown. * 144A securities are those that are exempt from registration under Rule 144A of the Securities Act of 1933, as amended. These securities are generally issued to qualified institutional buyers ( "QIBs "), such as the Fund. Any resale of these securities must generally be effected through a sale that is exempt from registration (e.g. a sale to another QIB), or the security must be registered for public sale. At January 31, 2006, the market value of 144A securities that could not be exchanged to the registered form is $209,892,768 or 8.9 % of net assets. @ Security, or portion of security, is on loan. + Security is purchased at a price that takes into account the value, if any, of accrued but unpaid interest. ++ Variable rate security.

FOREIGN CURRENCY ABBREVIATIONS CAD Canadian Dollar EUR European Monetary Unit GBP British Pound Sterling See accompanying notes to Schedule of Investments 9 NOTES TO SCHEDULE OF INVESTMENTS (UNAUDITED) NOTE 1 PORTFOLIO VALUATION. In computing the Fund's net asset value, portfolio securities that are traded on a securities exchange in the United States, except for option securities, are valued at the last reported sale price as of the time of valuation, or lacking any current reported sale at the time of valuation, at the mean between the most recent bid and asked quotations. Each option security traded on a securities exchange in the United States is valued at the last current reported sale price as of the time of valuation if the last current reported sale price falls within the consolidated bid/ask quote for the option security. If the last current reported sale price as of the time of valuation does not fall within the consolidated bid/ask quote for the option security, the security is valued at the mid-point of the consolidated bid/ask quote for the option security. Each security traded in the over-the-counter market and quoted on the NASDAQ National Market System, is valued at the NASDAQ Official Closing Price ("NOCP"), as determined by NASDAQ, or lacking an NOCP, the last current reported sale price as of the time of valuation by NASDAQ, or lacking any current reported sale on NASDAQ at the time of valuation, at the mean between the most recent bid and asked quotations. Each over-the-counter option that is not traded through the Options Clearing Corporation is valued by the counterparty, or if the counterparty's price is not readily available then by using the Black-Scholes method. Each other security traded over-the-counter is valued at the mean between the most recent bid and asked quotations. Short-term securities with maturities of 60 days or less are valued at amortized cost, which approximates market value. When market quotations are not readily available or when the valuation methods mentioned above are not reflective of the fair value of the security, the security is priced at a fair value following procedures and/or guidelines approved by the Board of Trustees, which may include utilizing a systematic fair valuation model provided by an independent pricing system. The Fund may also use fair value pricing if the value of a security it holds is, pursuant to Board of Trustees' guidelines, materially affected by events occurring before the Fund's pricing time but after the close of the primary market or exchange on which the security is traded. These procedures may utilize valuations furnished by pricing services approved by the Board of Trustees, which may be based on market transactions for comparable securities and various relationships between securities that are generally recognized by institutional traders, a computerized matrix system, or appraisals derived from information concerning the securities or similar securities received from recognized dealers in those securities. When fair value pricing is employed, the value of the portfolio security used to calculate the Fund's net asset value may differ from quoted or official closing prices. Securities that are principally traded in a foreign market are valued at the last current sale price at the time of valuation or lacking any current or reported sale, at the time of valuation, at the mean between the most recent bid and asked quotations as of the close of the appropriate exchange or other designated time. Trading in securities on European and Far Eastern securities exchanges and over-the-counter markets is normally completed at various times before the close of business on each day on which the New York Stock Exchange ("NYSE") is open. Trading of these securities may not take place on every NYSE business day. In addition, trading may take place in various foreign markets on Saturdays or on other days when the NYSE is not open and on which the Fund's net asset value is not calculated. As stated above, if the market prices are not readily available or are not reflective of the fair value of the security, the security will be priced at a fair value following procedures approved by the Board of Trustees. In light of the judgment involved in fair value decisions, there can be no assurance that a fair value assigned to a particular security is accurate. INVESTMENT TRANSACTIONS. Short-term investment transactions are recorded on a trade date basis. Long-term investment transactions are recorded on a trade date plus one basis, except for fiscal quarter ends, which are recorded on trade date. FOREIGN CURRENCY TRANSLATION. Except for securities of foreign issuers valued by a pricing service, values of investments and other assets and liabilities denominated in foreign currencies are translated into U.S. dollars using a rate selected by the advisor from rates quoted by any major bank or dealer in the particular currency market, as reported by a recognized quotation dissemination service. OPTION TRANSACTIONS. For hedging and investment purposes, the Fund may purchase or write (sell) put and call options. One of the risks associated with purchasing an option among others, is that the Fund pays a premium whether or not the option is exercised. Additionally, the Fund bears the risk of loss of premium and change in market value should the counterparty not perform under the contract. Put and call options purchased are accounted for in the same manner as portfolio securities. The cost of securities acquired through the exercise of purchased call options is increased by premiums paid. The proceeds from securities sold through the exercise of purchased put options are decreased by the premiums paid. When the Fund writes an option, an amount equal to the premium received by the Fund is recorded as a liability and is subsequently adjusted to the current value of the option written. Premiums received from writing options that expire unexercised are treated by the Fund on the expiration date as realized gains from written options. The difference between the premium and the amount paid on effecting a closing purchase transaction, including brokerage commissions, is also treated as a realized gain, or, if the premium is less than the amount paid for the closing purchase transaction, as a realized loss. If a call option is exercised, the premium is added to the proceeds from the sale of the underlying security or currency in determining whether the Fund has realized again or loss. If a put option is exercised, the premium reduces the cost basis of the securities purchased by the Fund. The Fund as writer of an option bears the market risk of an unfavorable change in the price of the security underlying the written option. NOTE 2 INVESTMENTS. The following information is presented on an income tax basis as of January 31, 2006. Differences between amounts for financial statements and Federal income tax purposes are primarily due to timing differences. The cost basis of investments for Federal income tax purposes at January 31, 2006 was as follows: Cost basis of investments $3,838,177,300 -------------- Gross unrealized appreciation 275,138,580 Gross unrealized depreciation (169,134,869) -------------- Net unrealized appreciation (depreciation) $ 106,003,711 ============== NOTE 3 SYNTHETIC CONVERTIBLE SECURITIES. The Fund may establish a "synthetic" convertible instrument by combining separate securities that possess the economic characteristics similar to a convertible security, i.e., fixed-income securities ("fixed-income component") and the right to acquire equity securities ("convertible component"). The fixed-income component is achieved by investing in non-convertible, fixed income securities such as bonds, preferred stocks and money market instruments. The convertible component is achieved by investing in warrants or options to buy common stock at a certain exercise price, or options on a stock index. In establishing a synthetic instrument, the Fund may pool a basket of fixed-income securities and a basket of warrants or options that produce the economic characteristics similar to a convertible security. Within each basket of fixed-income securities and warrants or options, different companies may issue the fixed-income and convertible components, which may be purchased separately and at different times. The Fund may purchase synthetic securities created by other parties, typically investment banks, including convertible structured notes. Convertible structured notes are fixed-income debentures linked to equity. Convertible structured notes have the attributes of a convertible security; however, the investment bank that issued the convertible note assumes the credit risk associated with the investment, rather than the issuer of the underlying common stock into which the note is convertible. Purchasing synthetic convertible securities may offer more flexibility than purchasing a convertible security. Different companies may issue the fixed-income and convertible components, which may be purchased separately and at different times. NOTE 4 PREFERRED SHARES. There are unlimited shares of Auction Rate Cumulative Preferred Shares ("Preferred Shares") authorized. The Preferred Shares have rights as determined by the Board of Trustees. The 43,200 Preferred Shares outstanding consist of seven series, 7,040 shares of M, 7,040 shares of TU, 7,040 shares of W, 7,040 shares of TH, 7,040 shares of F, 4,000 shares of A, and 4,000 shares of B. The Preferred Shares have a liquidation value of $25,000 per share plus any accumulated but unpaid dividends, whether or not declared. Dividends on the Preferred Shares are cumulative at a rate typically reset every seven or twenty-eight days based on the results of an auction. Dividend rates ranged from 3.70% to 4.61% for the period ended January 31, 2006. Under the Investment Company Act of 1940, the Fund may not declare dividends or make other distributions on shares of common stock or purchase any such shares if, at the time of the declaration, distribution or purchase, asset coverage with respect to the outstanding Preferred Shares would be less than 200%. The Preferred Shares are redeemable at the Fund's option, in whole or in part, on any dividend payment date at $25,000 per share plus any accumulated but unpaid dividends. The Preferred Shares are also subject to mandatory redemption at $25,000 per share plus any accumulated but unpaid dividends, whether or not declared, if certain requirements relating to the composition of the assets and liabilities of the Fund as set forth in the Statement of Preferences are not satisfied. The holders of Preferred Shares have voting rights equal to the holders of common stock (one vote per share) and will vote together with holders of shares of common stock as a single class except on matters affecting only the holders of Preferred Shares or the holders of common shares. NOTE 5 INTEREST RATE TRANSACTIONS. The Fund may enter into interest rate swap or cap transactions to attempt to protect itself from increasing dividend or interest expense on its leverage resulting from increasing short-term interest rates. A decline in interest rates may result in a decline in the value of the swap or cap, which may result in a decline in the Fund's net asset value. In addition, if the counterparty to an interest rate swap or cap defaults, the Fund would not be able to use the anticipated receipts under the swap or cap to offset the dividend or interest payments on the Fund's leverage. At the time an interest rate swap or cap reaches its scheduled termination, there is a risk that the Fund would not be able to obtain a replacement transaction or that the terms of the replacement would not be as favorable as on the expiring transaction. In addition, if the Fund is required to terminate any swap or cap early due to the Fund failing to maintain a required 200% asset coverage of the liquidation value of the outstanding Preferred Shares or the Fund loses its credit rating on its Preferred Shares, then the Fund could be required to make a termination payment, in addition to redeeming all or some of the Preferred Shares. Net unrealized gains are reported as an asset and net unrealized losses are reported as a liability on the Statement of Assets and Liabilities. The change in the value of the swaps, including periodic amounts of interest to be paid or received on swaps is reported as unrealized gains or losses in the Statement of Operations. A realized gain or loss is recorded upon payment or termination of swap agreements. Details of the swap agreements outstanding as January 31, 2006 were as follows: Unrealized Termination Notional Fixed Rate Floating Rate Appreciation Counterparty Date Amount (000) (Fund Pays) (Fund Receives) (Depreciation) ------------ ------------ ------------ ----------- --------------- -------------- Citibank NA June 4, 2006 $150,000 3.04% 1month LIBOR $ 998,342 Citibank NA June 4, 2007 150,000 3.61% 1month LIBOR 2,472,081 Citibank NA June 4, 2009 200,000 4.34% 1month LIBOR 2,963,138 ---------- $6,433,561 ========== NOTE 6 SECURITIES LENDING. During the period ended January 31, 2006, the Fund lent certain of its securities to broker-dealers and banks. Any such loan must be continuously secured by collateral in cash or cash equivalents maintained on a current basis in an amount at least equal to the market value of the securities loaned by the Fund. The Fund continues to receive the equivalent of the interest or dividends paid by the issuer on the securities loaned and also receives an additional return that may be in the form of a fixed fee or a percentage of the collateral. The Fund may pay reasonable fees to persons unaffiliated with the Fund for services in arranging these loans. The Fund has the right to call the loan and obtain the securities loaned at any time on notice of not more than five business days. The Fund does not have the right to vote the securities during the existence of the loan but could call the loan in an attempt to permit voting of the securities in certain circumstances. Upon return of the securities loaned, the cash or cash equivalent collateral will be returned to the borrower. In the event of bankruptcy or other default of the borrower, the Fund could experience both delays in liquidating the loan collateral or recovering the loaned securities and losses, including (a) possible decline in the value of the collateral or in the value of the securities loaned during the period while the Fund seeks to enforce its rights thereto, (b) possible subnormal levels of income and lack of access to income during this period, and (c) the expenses of enforcing its rights. In an effort to reduce these risks, Calamos Advisors LLC and the security lending agent will monitor the creditworthiness of the firms to which the Fund lends securities. At January 31, 2006, the Fund had securities valued at $494,352,997 that were on loan to broker-dealers and banks and $508,407,067 in cash or cash equivalent collateral. ITEM 2.
