    The Fund may invest in “zero coupon” securities. A zero coupon security does not pay a regular interest 
    coupon to its holders during the life of the security. Tax-exempt income to the holder of the security comes 
    from accretion of the difference between the original purchase price of the security at issuance and the par 
    value of the security at maturity and is effectively paid at maturity. Such securities are included in the 
    Portfolio of Investments with a 0.000% coupon rate in their description. The market prices of zero coupon 
    securities generally are more volatile than the market prices of securities that pay interest periodically. 
(1)    All percentages shown in the Portfolio of Investments are based on net assets applicable to Common 
    shares unless otherwise noted. 
(2)    Optional Call Provisions: Dates (month and year) and prices of the earliest optional call or redemption. 
    There may be other call provisions at varying prices at later dates. Certain mortgage-backed securities may 
    be subject to periodic principal paydowns. 
(3)    Ratings: Using the higher of Standard & Poor’s Group (“Standard & Poor’s”) or Moody’s Investor Service, 
    Inc. (“Moody’s”) rating. Ratings below BBB by Standard & Poor’s or Baa by Moody’s are considered to be 
    below investment grade. 
    The AAA ratings shown in the Portfolio of Investments reflect the AAA ratings on certain bonds that may be 
    insured by AMBAC, FGIC, XLCA or MBIA as of January 31, 2008. Subsequent to January 31, 2008, at least 
    one rating agency reduced the rating for AMBAC-insured bonds to AA and XLCA-insured and FGIC-insured 
    bonds experienced further downgrades such that they no longer carry AAA ratings which had the effect of 
    reducing the rating of many (if not all) of the bonds insured by those particular insurers. One or more 
    rating agencies have placed each of these insurers on “negative credit watch”, which may presage one or 
    more rating reductions for such insurer or insurers in the future. If one or more insurers’ ratings are 
    reduced below AAA by these rating agencies, it would likely reduce the effective rating of many of the 
    bonds insured by that insurer or insurers. 
(4)    Portion of investment, with an aggregate market value of $1,701,528, has been pledged to collateralize 
    the net payment obligations under forward swap contracts. 
(5)    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 be 
    equivalent to AAA rated securities. 
(6)    Investment has a maturity of more than one year, but has variable rate and demand features which qualify 
    it as a short-term investment. The rate dislosed is that in effect at the end of the reporting period. This 
    rate changes periodically based on market conditions or a specified market index. 
(7)    Preferred Shares, at Liquidation Value as a percentage of total investments is (33.4)%. 
(8)    Effective date represents the date on which both the Fund and counterparty commence interest payment 
    accruals on each forward swap contract. 
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. 

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 the treatment of paydown gains and losses, 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 January 31, 2008, the cost of investments was $355,007,501.
