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, 2010:


	Level 1	Level 2	Level 3	Total
Investments:
Municipal Bonds	$ —	$658,945,064	$ —	$658,945,064
Investment Companies	1,296,623	—	—	1,296,623
Total	$1,296,623	$658,945,064	$ —	$660,241,687

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 securities reflected as financing transactions, if any. 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, 2010, the cost of investments was $617,709,165.

Gross unrealized appreciation and gross unrealized depreciation of investments at January 31, 2010, were as follows:


Gross unrealized:
Appreciation	$ 37,473,124
Depreciation	(23,352,687)
Net unrealized appreciation (depreciation) of investments	$ 14,120,437


	At least 80% of the Fund’s net assets are invested in municipal securities that guarantee 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 whose insurer has experienced
	downgrades as of the end of the reporting period. Subsequent to the reporting period, 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)	MuniFund Term Preferred Shares and Auction Rate Preferred Shares, at Liquidation Value as a percentage
	of Total Investments are 16.4% and 13.9%, respectively.
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.
