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 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	$ —	$752,581,420	$746,988	$753,328,408
Common Stocks	9,123,311	—	—	9,123,311
Corporate Bonds	—	—	5,843	5,843
Total	$9,123,311	$752,581,420	$752,831	$762,457,562

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, 2015, the cost of investments was $690,106,407.

Gross unrealized appreciation and gross unrealized depreciation of investments as of July 31, 2015, were as follows:


Gross unrealized:
Appreciation	$ 92,703,809
Depreciation	(33,632,633)
Net unrealized appreciation (depreciation) of investments	$ 59,071,176


(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)		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.
(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. For fair value measurement disclosure purposes, investment classified as Level 3.
(8)		On July 28, 2015, the Fund's Adviser determined it was unlikely that this borrower would fulfill its entire

		interest payment obligations and has ceased accruing additional income on the Fund's records.

(11)		On May 7, 2015, the Fund's Adviser determined it was unlikely that this borrower would fulfill its entire

(13)		On April 1, 2013, the Fund's Adviser determined it was unlikely that this borrower would fulfill its entire

		(“AAL”) filed for federal bankruptcy protection. On December 9, 2013, AMR emerged from federal
		bankruptcy with the acceptance of its reorganization plan by the bankruptcy court. Under the settlement
		agreement established to meet AMR’s unsecured bond obligations, the bondholders, including the Fund,
		received a distribution of AAL preferred stock which was converted to AAL common stock over a 120-day
		period. Every 30 days, a quarter of the preferred stock was converted to AAL common stock based on the
		5-day volume-weighted average price and the amount of preferred shares tendered during the optional
		preferred conversion period.
(16)		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
