	At least 80% of the Fund’s net assets (including net assets attributable to Auction Rate Preferred shares)
	are invested in municipal securities that are covered by insurance or backed by an escrow or trust account
	containing sufficient U.S. Government or U.S. Government agency securities or U.S. Treasury-issued State
	and Local Government Series securities to ensure the timely payment of principal and interest.
(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 ACA, AGC, AMBAC, CIFG,
	FGIC, FSA, MBIA, RAAI and SYNCORA as of January 31, 2009. Subsequent to January 31, 2009, and
	during the period this Portfolio of Investments was prepared, there may have been reductions to the
	ratings of certain bonds resulting from changes to the ratings of the underlying insurers both during the
	period and after period end. Such reductions would likely reduce the effective rating of many of the bonds
	insured by that insurer or insurers presented at period end.
(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)	Investment has a maturity of more than one year, but has variable rate and demand features which qualify
	it as a short-term investment. The rate disclosed is that in effect at the end of the reporting period. This
	rate changes periodically based on market conditions or a specified market index.
(6)	Auction Rate Preferred Shares, at Liquidation Value as a percentage of Total Investments is 35.8%.
N/R	Not rated.
WI/DD	Purchased on a when-issued or delayed delivery basis.
(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.

Fair Value Measurements

During the current fiscal period, the Fund adopted the provisions of Statement of Financial Accounting Standards No. 157 (SFAS No. 157) “Fair Value Measurements.” SFAS No. 157 defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosure about fair value measurements. In determining the value of the Fund’s investments various inputs are used. These inputs are summarized in the three broad levels listed below:

Level 1 – Quoted prices in active markets for identical securities.
Level 2 – Other significant observable inputs (including quoted prices for similar securities, interest
rates, prepayment speeds, credit risk, etc.).
Level 3 – Significant unobservable inputs (including management’s assumptions in determining
the fair value of investments).

The inputs or methodology used for valuing securities are not an indication of the risk associated with investing in those securities.

The following is a summary of the Fund’s fair value measurements as of January 31, 2009:

	Level 1	Level 2	Level 3	Total
Investments	$1,283,377	$633,568,686	$ —	$634,852,063

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, 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, 2009, the cost of investments was $626,697,874.

Gross unrealized appreciation and gross unrealized depreciation of investments at January 31, 2009, were as follows:

Gross unrealized:
Appreciation	$ 31,447,439
Depreciation	(37,434,567)
Net unrealized appreciation (depreciation) of investments	$ (5,987,128)
