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

* 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 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 January 31, 2017, the cost of investments (excluding investments in derivatives) was $5,396,511,405.

Gross unrealized appreciation and gross unrealized depreciation of investments (excluding investments in derivatives) as of January 31, 2017, were as follows:

Gross unrealized:
Appreciation	$418,040,660
Depreciation	(55,277,745)
Net unrealized appreciation (depreciation) of investments	$362,762,915

(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)	Investment, or portion of investment, has been pledged to collateralize the net payment obligations for
	investments in derivatives and/or inverse floating rate transactions.
(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 ratings of such securities.
(6)	The coupon for this security increased 0.25% effective January 1, 2016 and increased 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)	On May 7, 2015, the Fund's Adviser determined it was unlikely that this borrower would fulfill its entire
	obligation on this security, and therefore reduced the security's interest rate of accrual from 5.250%
	to 2.100%.
(9)	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.
(10)	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. On January 18, 2017, the Fund's Adviser determined it was likely that this senior interest corporate
	bond would fulfill its obligation on this security maturing on July 15, 2019, and therefore began accruing
	income on the Fund's records.
(11)	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.
(12)	On November 28, 2011, AMR Corp. (“AMR”), the parent company of American Airlines Group, Inc. (“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.
(13)	Investment has a maturity of greater 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.
(14)	Variable Rate Demand Preferred Shares, at Liquidation Preference as a percentage of Total Investments
	is 21.9%.
(15)	Variable Rate MuniFund Term Preferred Shares, at Liquidation Preference as a percentage of Total
	Investments is 13.1%.
(16)	Other assets less liabilities includes the unrealized appreciation (depreciation) of certain over-the-counter
	(“OTC”) derivatives as well as the unrealized appreciation (depreciation) of OTC-cleared and exchange-
	traded derivatives, when applicable.
(17)	Effective date represents the date on which both the Fund and counterparty commence interest payment
	accruals on each contract.
(ETM)	Escrowed to maturity.
(IF)	Inverse floating rate investment.
(UB)	Underlying bond of an inverse floating rate trust reflected as a financing transaction.
