Security Valuation - The Fund uses the amortized cost method for valuing its short-term securities. Under this method, all investments purchased at a discount or premium are valued by amortizing the difference between the original purchase price and the maturity value of the issue over the period to maturity.

Fair Value Measurement - On January 1, 2008, the Fund adopted Statement of Financial Accounting Standards No. 157 (“SFAS 157”), “Fair Value Measurements.” SFAS 157 establishes a three-tier hierarchy to classify the assumptions, referred to as inputs, used in valuation techniques (see Security Valuation above) to measure fair value of the Fund’s investments. These inputs are summarized in three broad levels: Level 1 – quoted prices in active markets for identical investments; Level 2 – other significant observable inputs (including quoted prices in inactive markets or for similar investments); and Level 3 – significant unobservable inputs (including the Fund’s own assumptions in determining fair value). The inputs or methodology used for valuing securities may not be an indication of the risk associated with investing in those securities.

The following is a summary of the value of the Fund’s investments as of March 31, 2008 based on the level of inputs used:

Valuation Inputs	Value
Level 1 - Quoted Prices	$	0
Level 2 - Other Significant Observable Inputs		210,421,910
Level 3 - Significant Unobservable Inputs		0
Total	$	210,421,910
