Fair Value Measurements

Fair value is defined as the price that the Fund would receive upon selling an investment or transferring a liability in an orderly transaction to an independent buyer in the principal or most advantageous market for the investment. A three-tier hierarchy is used to maximize the use of observable market data and minimize the use of unobservable inputs and to establish classification of fair value measurements for disclosure purposes. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability. Observable inputs are based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability. Unobservable inputs are based on the best information available in the circumstances. The following is a summary of the three-tiered hierarchy of valuation input levels.

Level 1 – Inputs are unadjusted and prices are determined using quoted prices in active markets for identical securities.

Level 2 – Prices are determined using other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.).

Level 3 – Prices are determined using significant unobservable inputs (including management's assumptions in determining the fair value of investments).

The inputs or methodologies used for valuing securities are not an indication of the risks associated with investing in those securities. The following is a summary of the Fund's fair value measurements as of the end of the reporting period:


	Level 1	Level 2	Level 3	Total
Long-Term Investments:
Municipal Bonds	$ —	$2,102,467,831	$1,374,636	$2,103,842,467
Corporate Bonds	—	—	169,096	169,096
Total	$ —	$2,102,467,831	$1,543,732	$2,104,011,563

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.

As of July 31, 2013, the cost of investments was $1,972,675,175.

Gross unrealized appreciation and gross unrealized depreciation of investments as of July 31, 2013, were as follows:


Gross unrealized:
Appreciation	$ 90,529,258
Depreciation	(61,094,126)
Net unrealized appreciation (depreciation) of investments	$ 29,435,132


(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 highest of Standard & Poor’s Group ("Standard & Poor's"), Moody’s Investors Service,
		Inc. ("Moody's") or Fitch, Inc. ("Fitch") rating. Ratings below BBB by Standard & Poor’s, Baa by Moody’s
		or BBB by Fitch are considered to be below investment grade. Holdings designated N/R are not rated
		by any of these national rating agencies.

(4)		At or subsequent to the end of the reporting period, this security is non-income producing. Non-income
		producing, in the case of a fixed-income security, generally denotes that the issuer has (1) defaulted on
		the payment of principal or interest, (2) is under the protection of the Federal Bankruptcy Court or (3) the
		Fund’s Adviser has concluded that the issue is not likely to meet its future interest payment obligations
		and has directed the Fund’s custodian to cease accruing additional income on the Fund’s records.
(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. Certain bonds backed by U.S. Government or
		agency securities are regarded as having an implied rating equal to the rating of such securities.
(6)		Investment, or portion of investment, has been pledged to collateralize the net payment obligations for
		investments in inverse floating rate transactions.
(7)		Investment valued at fair value using methods determined in good faith by, or at the discretion of, the
		Board of Directors. For fair value measurement disclosure purposes, investment classified as Level 3.
(8)		During January 2010, Las Vegas Monorail Company (“Las Vegas Monorail”) filed for federal bankruptcy
		protection. During March 2012, Las Vegas Monorail emerged from federal bankruptcy with the acceptance
		of a reorganization plan assigned by the Federal Bankruptcy Court. Under the reorganization plan, the Fund
		surrendered its Las Vegas Monorail Project Revenue Bonds, First Tier, Series 2000 and in turn received two
		senior interest corporate bonds: the first with an annual coupon rate of 5.500% maturing on July 15, 2019 and the
		second with an annual coupon rate of 3.000% (5.500% after December 31, 2015) maturing on July 15, 2055. The
		Fund’s custodian is not accruing income on the Fund’s records for either senior interest corporate bond.
(9)		Variable Rate Demand Preferred Shares, at Liquidation Value as a percentage of Total Investments
		is 31.7%.
WI/DD		Investment, or portion of investment, purchased on a when-issued or delayed delivery basis.
(ETM)		Escrowed to maturity.
(IF)		Inverse floating rate investment.
(UB)		Underlying bond of an inverse floating rate trust reflected as a financing transaction.
