    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 reflects the AAA ratings on certain bonds insured
    by AMBAC, FGIC, XCLA or MBIA and/or the A ratings on certain bonds insured by ACA as of
    November 30, 2007. Subsequent to the November 30, 2007, at least one rating agency reduced
    the rating for AMBAC-insured bonds to AA, the rating for XCLA-insured bonds to A and the rating for ACA 
    to CCC, and 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 (or A in the case of ACA) by these rating agencies, it would likely       
reduce the effective rating of many of the bonds insured by that insurer or insurers.       
(4)    The issuer has received a formal adverse determination from the Internal Revenue Service (the “IRS”) 
    regarding the tax-exempt status of the bonds’ coupon payments. The Fund will continue to treat coupon 
    payments as tax-exempt income until such time it is formally determined that the interest on the bonds 
    should be treated as taxable. 
(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)    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 November 30, 2007, the cost of investments was $516,826,109.

  Appreciation    $21,961,923 
  Depreciation    (4,717,812) 
Net unrealized appreciation (depreciation) of investments    $17,244,111
