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 of 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 February 28, 2011:


	Level 1	Level 2	Level 3	Total
Investments:
Municipal Bonds	$ —	$39,548,309	$ —	$39,548,309

The following is a reconciliation of the Fund’s Level 3 investments held at the beginning and end of the measurement period:


	Level 3
	Municipal Bonds
Balance at the beginning of period	$ 688,820
Gains (losses):
Net realized gains (losses)	(149,533)
Net change in unrealized appreciation (depreciation)	311,180
Purchases at cost	—
Sales at proceeds	(850,467)
Net discounts (premiums)	—
Transfers Into	—
Transfers out of	—
Balance at the end of period	$ —
During the period ended February 28, 2011, the Fund recognized no significant transfers to/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 February 28, 2011, the cost of investments was $39,676,018.

Gross unrealized appreciation and gross unrealized depreciation of investments at February 28, 2011, were as follows:


Gross unrealized:
Appreciation	$ 659,001
Depreciation	(1,836,710)
Net unrealized appreciation (depreciation) of investments	$(1,177,709)


(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 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)		The Fund’s Adviser has concluded this 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.
(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. Such investments are normally considered to
		be equivalent to AAA rated securities.
(6)		MuniFund Term Preferred Shares, at Liquidation Value as a percentage of Total Investments is 37.2%.
N/R		Not rated.
(IF)		Inverse floating rate investment.
(UB)		Underlying bond of an inverse floating rate trust reflected as a financing transaction.
