Fair Value Measurements

Financial Accounting Standards Board Statement of Financial Accounting Standards No. 157, “Fair Value Measurements,” establishes a three-tier hierarchy for measuring fair value and requires additional disclosure about the classification of fair value measurements.

Various inputs are used in determining the value of the Fund's investments. These inputs are summarized in three broad levels. Level 1 includes quoted prices in active markets for identical securities. Level 2 includes other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, and credit risk). Level 3 includes significant unobservable inputs (including the Fund's own assumptions in determining the fair value of investments). The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

The following is a summary of the inputs used as of May 31, 2009 in valuing the Fund's investments:

Valuation Inputs	Investments in Securities
Level 1	$ -
Level 2	43,495,726
Level 3	53,944
Total	$ 43,549,670

The following is a reconciliation of the Fund's Level 3 investments for which significant unobservable inputs were used in determining the value at May 31, 2009:
