Futures Contracts

 

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 June 30, 2009, 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 may enter into interest rate swap contracts. The Fund may also purchase and sell U.S. Treasury futures contracts to hedge against changes in interest rates.

 

At June 30, 2009, the aggregate fair value of derivative instruments (not accounted for as hedging instruments under Financial Accounting Standards Board (FASB) Statement of Financial Accounting Standards No. 133) in an asset position and in a liability position and whose primary underlying risk exposure is interest rate risk was $5,523 and $87,955, respectively.

Gross unrealized appreciation		$	1,256,915
Gross unrealized depreciation			(2,120,797	)

The Fund adopted FASB Statement of Financial Accounting Standards No. 157 (FAS 157), “Fair Value Measurements”, effective October 1, 2008.
