At October 31, 2012, the cost and related gross unrealized appreciation and depreciation on investments for tax purposes
are as follows:

 

Cost of Investments for Tax Purposes			Gross Tax Unrealized Appreciation				Gross Tax Unrealized Depreciation				Net Tax Unrealized Appreciation on Investments
$	156,777,458		$	15,235,580			$	-			$	15,235,580

 

The municipal bonds and preferred shares in which the Fund invests are traded primarily in the over-the-counter markets.  In determining net asset value, the Fund uses the valuations of portfolio securities furnished by a pricing service approved by the Board of Trustees.  The pricing service typically values portfolio securities at the bid price or the yield equivalent when quotations are readily available.  Securities for which quotations are not readily available are valued at fair market value on a consistent basis as determined by the pricing service using a matrix system to determine valuations.  The procedures of the pricing service and its valuations are reviewed by the officers of the Fund under the general supervision of the Board of Trustees.  Positions in futures contracts, interest rate swaps and options on interest rate swaps ("swaptions") are valued at closing prices for such contracts established by the exchange or dealer market on which they are traded.
For those securities where quotations or prices are not available, the valuations are determined in accordance with procedures established in good faith by management and approved by the Board of Trustees. Valuations in accordance with these procedures are intended to reflect each security’s (or asset’s) “fair value”.  Fair value is defined as the price that the Fund would receive to sell an investment or pay to transfer a liability in an orderly transaction with an independent buyer in the principal market, or in the absence of a principal market, the most advantageous market for the investment or liability. Each such determination should be based on a consideration of all relevant factors, which are likely to vary from one pricing context to another. Examples of such factors may include, but are not limited to: (i) the type of security, (ii) the initial cost of the security, (iii) the existence of any contractual restrictions on the security’s disposition, (iv) the price and extent of public trading in similar securities of the issuer or of comparable companies, (v) quotations or evaluated prices from broker-dealers and/or pricing services, (vi) information obtained from the issuer, analysts, and/or the appropriate stock exchange (for exchange traded securities), (vii) an analysis of the company’s financial statements, and (viii) an evaluation of the forces that influence the issuer and the market(s) in which the security is purchased and sold (e.g. the existence of pending merger activity, public offerings or tender offers that might affect the value of the security).
There are three different categories for valuations.  Level 1 valuations are those based upon quoted prices in active markets.  Level 2 valuations are those based upon quoted prices in less active markets or based upon significant observable inputs (e.g. yield curves; benchmark interest rates; indices).  Level 3 valuations are those based upon unobservable inputs (e.g. discounted cash flow analysis; non-market based methods used to determine fair valuation).
The Fund values Level 1 securities using readily available market quotations in active markets.  The Fund values Level 2 fixed income securities using independent pricing providers who employ matrix pricing models utilizing market prices, broker quotes and prices of securities with comparable maturities and qualities.  The Fund values Level 2 equity securities using various observable market inputs as described above. The Fund did not have any Level 3 securities at October 31, 2012.
The following table represents the Fund's investments carried by caption and by level within the fair value hierarchy as of October 31, 2012.

 

Valuations (in $000s)	Level 1				Level 2				Level 3				Total

Assets:

Preferred Shares		-				2,120				-				2,120
Total	$	-			$	172,013			$	-			$	172,013

 

During the three months ended October 31, 2012, there were no transfers between levels.
