(1)    All percentages shown in the Portfolio of Investments are based on net assets applicable to Common shares

(2)    Optional Call Provisions: Dates (month and year) and prices of the earliest optional call or redemption. There

    subject to periodic principal paydowns. 
(3)    Ratings: Using the higher of Standard & Poor’s Group (“Standard & Poor’s”) or Moody’s Investor Service, 
    (“Moody’s”) rating. Ratings below BBB by Standard & Poor’s or Baa by Moody’s are considered to be below 
    investment grade. 
    The Portfolio of Investments may reflect the ratings on certain bonds insured by ACA, AMBAC, CIFG, 
    FGIC, MBIA, RAAI and XLCA as of July 31, 2008. Subsequent to July 31, 2008, and during the period this 
    Portfolio of Investments was prepared, there may have been reductions to the ratings of certain bonds 
    resulting from changes to the ratings of the underlying insurers both during the period and after the 
    period end. Such reductions would likely reduce the effective rating of many of the bonds insured by 
    that insurer or insurers presented at period end. 
(4)    Backed by an escrow or trust containing sufficient U.S. Government or U.S. Government agency securities 
    which ensure the timely payment of principal and interest. Such investments are normally considered to 
    equivalent to AAA rated securities. 
(5)    Investment has a maturity of more than one year, but has a variable rate and demand features which 
    qualify it as a short-term investment. The rate disclosed is that in effect at the end of the reporting 
    period. This rate changes periodically based on market conditions or a specified market index. 
(6)    Preferred Shares, at Liquidation Value as a percentage of total investments is (35.1)%. 
N/R    Not rated. 
(ETM)    Escrowed to maturity. 
(IF)    Inverse floating rate investment. 
(UB)    Underlying bond of an inverse floating rate trust reflected as a financing transaction pursuant to the 
    provisions of SFAS No. 140. 

Fair Value Measurements 
During the current fiscal period, the Fund adopted the provisions of Statement of Financial Accounting 
Standards No. 157, Fair Value Measurements (SFAS 157). SFAS 157 defines fair value, establishes a 
framework for measuring fair value in generally accepted accounting principles, and expands disclosure 
about fair value measurements. In determining the value of the Fund’s investments various inputs are 
used. These inputs are summarized in the three broad levels listed below: 
   Level 1 – Quoted prices in active markets for identical securities. 
   Level 2 – Other significant observable inputs (including quoted prices for similar securities, interest rates, 
                 prepayment speeds, credit risk, etc.). 
   Level 3 – Significant unobservable inputs (including management’s assumptions in determining the fair 
                 value of investments). 
The inputs or methodology used for valuing securities are not an indication of the risk associated with 
investing in those securities. 

The following is a summary of the Fund’s fair value measurements as of July 31, 2008:                 
    Level 1    Level 2     Level 3    Total 
Investments    $ —     $ 376,556,635    $ —     $ 376,556,635 

Income Tax Information

The following information is presented on an income tax basis. Differences between amounts for financial statement and federal income tax purposes are primarily due to timing differences in recognizing taxable market discount, timing differences in recognizing certain gains and losses on investment transactions and the treatment of investments in inverse floating rate transactions subject to SFAS No 140.

To the extent that differences arise that are permanent in nature, such amounts are reclassified within the capital accounts on the Statement of Assets and Liabilities presented in the annual report, based on their federal tax basis treatment; temporary differences do not require reclassification. Temporary and permanent differences do not impact the net asset value of the Fund.

At July 31, 2008, the cost of investments was $356,016,415.

Gross unrealized appreciation and gross unrealized depreciation of investments at July 31, 2008, were as follows:

Gross unrealized:     
 Appreciation    $ 10,752,435 
 Depreciation    (11,882,304)
Net unrealized appreciation (depreciation) of investments    $ (1,129,869)
