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 three-tier hierarchy of inputs is summarized in the three broad levels listed below:

Level 1 – Quoted prices in active markets for identical securities.

Level 2 – Other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.).

Level 3 – 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 June 30, 2011:

	Level 1		Level 2		Level 3		Total
Investments:
Municipal Bonds	$	—	$	175,802,597	$	—	$	175,802,597
Common stocks		769		—		—		769
Total	$	769	$	175,802,597	$	—	$	175,803,366

During the period ended June 30, 2011, the Fund recognized no significant transfers to or from Level 1, Level 2 or Level 3.

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.

At June 30, 2011, the cost of investments was $176,638,475.

Gross unrealized appreciation and gross unrealized depreciation of investments at June 30, 2011, were as follows:\


Gross unrealized:
Appreciation	$	5,781,168
Depreciation		(6,616,277	)
Net unrealized appreciation (depreciation) of investments	$	(835,109	)

(1)	All percentages shown in the Portfolio of Investments are based on net assets.
(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 Investor 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)	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)	At or subsequent to the end of the reporting period, this security is non-income producing. Non-income producing security, in the case of a bond, 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.
(6)	On December 9, 2002, UAL Corporation (“UAL”), the holding company of United Air Lines, Inc. (“United”) filed for federal bankruptcy protection. The Adviser determined that it was likely that United would not remain current on their interest payment obligations with respect to the bonds previously held and thus the Fund had stopped accruing interest on its UAL bonds. On February 1, 2006, UAL emerged from federal bankruptcy with the acceptance of its reorganization plan by the bankruptcy court. Under the settlement agreement established to meet UAL’s unsecured bond obligations, the bondholders, including the Fund, received three distributions of UAL common stock over the subsequent months, and the bankruptcy court dismissed all unsecured claims of bondholders, including those of the Fund. On May 5, 2006, the Fund liquidated such UAL common stock holdings. On September 29, 2006 and May 30, 2007, the Fund received additional distributions of 532 and 172 shares, respectively, of UAL common stock as a result of its earlier ownership of the UAL bonds. The Fund liquidated the 532 shares of such UAL common stock holdings on November 15, 2006. The Fund received an additional distribution of 48 UAL common stock shares on November 14, 2007. The remaining 220 shares of UAL common stock were liquidated by the Fund on March 30, 2010. The Fund received an additional distribution of 34 UAL common stock shares on July 20, 2010, which are still held by the Fund as of June 30, 2011. On October 1, 2010, UAL Corporation was renamed United Continental Holdings, Inc.
(7)	Non-income producing; issuer has not declared a dividend within the past twelve months.

N/R	Not rated.
(ETM)	Escrowed to maturity.
(IF)	Inverse floating rate investment.
