    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 with a 0.00% 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 or Moody’s rating. Ratings below BBB by Standard &  
    Poor’s Group or Baa by Moody’s Investor Service, Inc. are considered to be below investment grade.  
(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 be equivalent to AAA rated securities.  
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.
