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	$ —	$175,889,482	$ —	$175,889,482

* 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 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 June 30, 2016, the cost of investments (excluding investments in derivatives) was $117,607,987.

Gross unrealized appreciation and gross unrealized depreciation of investments (excluding investments in derivatives) as of June 30, 2016, were as follows:


Gross unrealized:
Appreciation	$54,257,748
Depreciation	(14,073)
Net unrealized appreciation (depreciation) of investments	$54,243,675

		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. 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)		Borrowings as a percentage of Total Investments is 6.8%.
(6)		The Fund may pledge up to 100% of its eligible investments (excluding any investments separately pledged
		as collateral for specific investments in derivatives, when applicable) as collateral for borrowings.

		(“OTC”) derivatives as well as the OTC-cleared and exchange-traded derivatives, when applicable.
(8)		Effective date represents the date on which both the Fund and Counterparty commence interest payment
		accruals on each contract.
(IF)		Inverse floating rate investment.
(UB)		Underlying bond of an inverse floating rate trust reflected as a financing transaction.
144A		Investment is exempt from registration under Rule 144A of the Securities Act of 1933, as amended.

		those transactions with qualified institutional buyers.
