Supplemental Information (Unaudited) 2/29/08

(1) Fair Value Disclosure

The fund adopted FASB Statement No. 157, Fair Value Measurements (the “Statement”) in this reporting period. This Statement provides a single definition of fair value, a hierarchy for measuring fair value and expanded disclosures about fair value measurements.

Various inputs are used in determining the value of the fund’s investments. These inputs are categorized into three broad levels. Level 1 include quoted prices in active markets for identical assets or liabilities. Level 2 include other significant observable market-based inputs (including quoted prices for similar securities, interest rates, prepayment speed, credit risk, etc.). Level 3 include unobservable inputs, which may include the adviser’s own assumptions in determining the fair value of investments. Other financial instruments are derivative instruments not reflected in Total Investments, such as futures, forwards, swap contracts and written options, which are valued at the unrealized appreciation/depreciation on the instrument. The following is a summary of the levels used as of February 29, 2008 in valuing the fund’s assets carried at market value:


	Level 1		Level 2		Level 3	Total
Investments in Securities			$	168,642,353		$	168,642,353
Other Financial Instruments	(1,414,872	)					(1,414,872	)

(2) Portfolio Securities

The cost and unrealized appreciation and depreciation in the value of the investments owned by the fund, as computed on a federal income tax basis, are as follows:


Aggregate Cost	$	171,562,501

Gross unrealized appreciation	$	6,677,287
Gross unrealized depreciation		(10,603,185	)

Net unrealized appreciation (depreciation)	$	(3,925,898	)

The aggregate cost above includes prior fiscal year end tax adjustments.

(3) Derivative Contracts at 2/29/08

Futures contracts outstanding at 2/29/08


Description	Contracts	Value		Expiration Date	Unrealized Appreciation (Depreciation)
U.S. Treasury Bond (Short)	117	$	13,879,125	Jun-08	$	(440,074	)
U.S. Treasury Note 10 yr (Short)	324		37,999,125	Jun-08		(974,798	)

					$	(1,414,872	)

At February 29, 2008, the fund had sufficient cash and/or other liquid securities to cover any commitments under these derivative contracts.
