    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. 
(5)    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.
