A summary of open financial instruments at December 31, 2010 is as follows:

 

Interest Rate Swaps

 

 

The effective date represents the date on which the Fund and the counterparty to the interest rate swap contract begin interest payment accruals.

 

At December 31, 2010, the Fund had sufficient cash and/or securities to cover commitments under these contracts.

 

The Fund is subject to interest rate risk in the normal course of pursuing its investment objectives. Because the Fund holds fixed rate bonds, the value of these bonds may decrease if interest rates rise. To hedge against this risk, the Fund enters into interest rate swap contracts.

 

At December 31, 2010, the aggregate fair value of derivative instruments (not considered to be hedging instruments for accounting disclosure purposes) in an asset position and in a liability position and whose primary underlying risk exposure is interest rate risk was $7,732 and $708, respectively.

The cost and unrealized appreciation (depreciation) of investments of the Fund at December 31, 2010, as determined on a federal income tax basis, were as follows:

 

Aggregate cost		$	37,755,500
Gross unrealized appreciation		$	689,235
Gross unrealized depreciation			(1,934,636	)
Net unrealized depreciation		$	(1,245,401	)

 

Under generally accepted accounting principles for fair value measurements, a three-tier hierarchy to prioritize the assumptions, referred to as inputs, is used in valuation techniques to measure fair value. The three-tier hierarchy of inputs is summarized in the three broad levels listed below.

 

 

In cases where the inputs used to measure fair value fall in different levels of the fair value hierarchy, the level disclosed is determined based on the lowest level input that is significant to the fair value measurement in its entirety. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

 

At December 31, 2010, the hierarchy of inputs used in valuing the Fund’s investments, which are carried at value, were as follows:

 

		Quoted Prices in
		Active Markets for				Significant Other				Significant
		Identical Assets				Observable Inputs				Unobservable Inputs
Asset Description		(Level 1)				(Level 2)				(Level 3)				Total
Tax-Exempt Investments		$	—			$	39,840,099			$	—			$	39,840,099
Total Investments		$	—			$	39,840,099			$	—			$	39,840,099
Interest Rate Swaps		$	—			$	7,732			$	—			$	7,732
Total		$	—			$	39,847,831			$	—			$	39,847,831
Liability Description
Interest Rate Swaps		$	—			$	(708	)		$	—			$	(708	)
Total		$	—			$	(708	)		$	—			$	(708	)

 

The Fund held no investments or other financial instruments as of September 30, 2010 whose fair value was determined using Level 3 inputs. At December 31, 2010, the value of investments transferred between Level 1 and Level 2, if any, during the fiscal year to date then ended was not significant.

 

For information on the Fund’s policy regarding the valuation of investments and other significant accounting policies, please refer to the Fund’s most recent financial statements included in its semiannual or annual report to shareholders.
