Supplemental Information (Unaudited) 2/28/09

(1) Fair Value Disclosure

The fund adopted FASB Statement No. 157, Fair Value Measurements (the “Statement”). 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 assets or liabilities carried at market value. These inputs are categorized into three broad levels. Level 1 includes quoted prices in active markets for identical assets or liabilities. Level 2 includes other significant observable market-based inputs (including quoted prices for similar securities, interest rates, prepayment speed, and credit risk). Level 3 includes 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. The following is a summary of the levels used as of February 28, 2009, in valuing the fund’s assets or liabilities carried at market value:

 

     Level 1    Level 2    Level 3    Total

Investments in Securities

   $ 1,158,509    $ 149,211,531    $ —      $ 150,370,040

Other Financial Instruments

   $ 346,828    $ —      $ —      $ 346,828

(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:

Gross unrealized depreciation

     (16,698,695 )

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