(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 insured 
    by AMBAC, FGIC, XCLA or MBIA and/or the A ratings on certain bonds insured by ACA as of December 31, 
    2007. During December 2007, at least one rating agency reduced the rating for ACA bonds to CCC. 
    Subsequent to December 31, 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 FGIC-insured bonds to A3. 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)    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. 
(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 December 31, 2007, the cost of investments was $52,761,725.
