A summary of open financial instruments at June 30, 2011 is as follows:

 

Futures Contracts

 

 

At June 30, 2011, the Trust had sufficient cash and/or securities to cover commitments under these contracts.

 

The Trust is subject to interest rate risk in the normal course of pursuing its investment objectives. Because the Trust holds fixed rate bonds, the value of these bonds may decrease if interest rates rise. The Trust purchases and sells U.S. Treasury futures contracts to hedge against changes in interest rates.

 

At June 30, 2011, 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 $256,850 and $112,430, respectively.

 

The cost and unrealized appreciation (depreciation) of investments of the Trust at June 30, 2011, as determined on a federal income tax basis, were as follows:

 

Aggregate cost		$	284,757,091
Gross unrealized appreciation		$	23,026,596
Gross unrealized depreciation			(3,281,396	)
Net unrealized appreciation		$	19,745,200

 

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 June 30, 2011, the hierarchy of inputs used in valuing the Trust’s investments, which are carried at value, were as follows:

 

Asset Description		Level 1				Level 2				Level 3				Total
Tax-Exempt Investments		$	—			$	348,932,291			$	—			$	348,932,291
Total Investments		$	—			$	348,932,291			$	—			$	348,932,291
Futures Contracts		$	256,850			$	—			$	—			$	256,850
Total		$	256,850			$	348,932,291			$	—			$	349,189,141
Liability Description
Futures Contracts		$	(112,430	)		$	—			$	—			$	(112,430	)
Total		$	(112,430	)		$	—			$	—			$	(112,430	)

 

The Trust held no investments or other financial instruments as of March 31, 2011 whose fair value was determined using Level 3 inputs. At June 30, 2011, 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 Trust’s policy regarding the valuation of investments and other significant accounting policies, please refer to the Trust’s most recent financial statements included in its semiannual or annual report to shareholders.
