Fair Value Measurements

Fair value is defined as the price that would be received 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 risk 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	$ —	$5,424,559,958	$ —	$5,424,559,958
Corporate Bonds	—	—	491,634	491,634
Investments in Derivatives:

Represents net unrealized appreciation (depreciation).

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. Temporary differences do not require reclassification. Temporary and permanent differences do not impact the net asset value of the Fund.

As of July 31, 2016, the cost of investments was $4,556,620,828.

Gross unrealized appreciation and gross unrealized depreciation of investments (excluding investments in derivatives) as of July 31, 2016, were as follows:

Gross unrealized:
Appreciation	$628,312,016
Depreciation	(5,421,185)
Net unrealized appreciation (depreciation) of investments	$622,890,831

(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)	For financial reporting purposes, the ratings disclosed are the highest of Standard & Poor’s Group
	("Standard & Poor's"), Moody’s Investors Service, Inc. ("Moody's") or Fitch, Inc. ("Fitch") rating. This
	treatment of split-rated securities may differ from that used for other purposes, such as for Fund
	investment policies. 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)	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, or portion of investment, has been pledged to collateralize the net payment obligations for
	investments in derivatives and/or inverse floating rate transactions.
(6)	The coupon for this security increased 0.25% effective January 1, 2016 and will increase an additional
	0.25% effective May 11, 2016.
(7)	Step-up coupon. The rate shown is the coupon as of the end of the reporting period.
(8)	As of, 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
	ceased accruing additional income on the Fund’s records.
(9)	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 is not accruing income for either senior interest corporate bond.
(10)	Investment valued at fair value using methods determined in good faith by, or at the discretion of, the Board.
	For fair value measurement disclosure purposes, investment classified as Level 3.
(11)	Variable Rate MuniFund Term Preferred Shares, at Liquidation Preference as a percentage of Total
	Investments is 26.0%.
(12)	Variable Rate Demand Preferred Shares, at Liquidation Preference as a percentage of Total Investments
	is 4.4%.
(13)	Other assets less liabilities includes the unrealized appreciation (depreciation) of certain over-the-counter
	derivatives (“OTC”) as presented on the Statement of Assets and Liabilities. The unrealized appreciation
	(depreciation) of OTC-cleared and exchange-traded derivatives is recognized as part of the cash collateral
	at brokers and/or the receivable or payable for variation margin as presented on the Statement of Assets
	and Liabilities, when applicable.
(14)	Effective date represents the date on which both the Fund and Counterparty commence interest payment
	accruals on each forward swap contract.
(ETM)	Escrowed to maturity.
(IF)	Inverse floating rate investment.
(UB)	Underlying bond of an inverse floating rate trust reflected as a financing transaction.
USD-LIBOR-ICE	United States Dollar-London Inter-Bank Offered Rated-Intercontinental Exchange.
USD-SIFMA	United States Dollar-Securities-Industry and Financial Market Association.
(WI/DD)	Investment, or portion of investment, purchased on a when-issued or delayed delivery basis.
