(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 Portfolio of Investments may reflect the ratings on certain bonds insured by AMBAC, CIFG, FGIC, MBIA
		and XLCA as of April 30, 2008. During the period covered by this report, at least one rating agency reduced
		the rating for AMBAC-insured and MBIA-insured bonds to AA and at least one rating agency further
		reduced the ratings for FGIC-insured and XLCA-insured bonds to BB. Subsequent to April 30, 2008, and at
		the time this report was prepared, at least one rating agency further reduced the rating for CIFG-insured
		bonds to BB and MBIA-insured bonds to A. As of April 30, 2008, at least one rating agency has placed
		XLCA-insured bonds on “negative credit watch” and one or more rating agencies have placed each of these
		insurers on “negative outlook”, which may presage one or more rating reductions for such insurer or insurers
		in the future. If one or more insurers’ ratings are reduced by these rating agencies, it would likely reduce
		the effective rating of many of the bonds insured by that insurer or insurers.
(4)		Investment valued at fair value using methods determined in good faith by, or at the discretion of, the
		Board of Directors/Trustees.
(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)		Preferred Shares, at Liquidation Value as a percentage of total investments is (35.7)%.
N/R		Not rated.

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 timing differences in recognizing taxable market discount and timing differences in recognizing certain gains and losses on investment transactions. 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 April 30, 2008, the cost of investments was $51,945,606.

Gross unrealized appreciation and gross unrealized depreciation of investments at April 30, 2008, were as follows:
