		At least 80% of the Fund’s net assets (including net assets attributable to Preferred shares) are invested in
		municipal securities that are either covered by Original Issue Insurance, Secondary Market Insurance or
		Portfolio Insurance which ensures the timely payment of principal and interest. Up to 20% of the Fund’s
		net assets (including net assets attributable to Preferred shares) may be invested in municipal securities
		that are (i) either backed by an escrow or trust containing sufficient U.S. Government or U.S. Government
		agency securities (also ensuring the timely payment of principal and interest), or (ii) rated, at the time of
		investment, within the four highest grades (Baa or BBB or better by Moody’s, Standard & Poor’s or Fitch)
		or unrated but judged to be of comparable quality by the Adviser.
		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 reflect the AAA ratings on certain bonds that may
		be insured by AMBAC, FGIC, XLCA or MBIA as of January 31, 2008. Subsequent to January 31, 2008, at
		least one rating agency reduced the rating for AMBAC-insured bonds to AA and XLCA-insured and
		FGIC-insured bonds experienced further downgrades such that they no longer carry AAA ratings which had
		the effect of reducing the rating of many (if not all) of the bonds insured by those particular insurers. 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 by these rating agencies, it would likely reduce the effective rating of many of the
		bonds insured by that insurer or insurers.
(4)		Preferred Shares, at Liquidation Value as a percentage of total investments is (33.5)%.
(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 January 31, 2008, the cost of investments was $641,567,287.
