(†) The Fund employs the amortized cost method of security valuation as set forth in Rule 2a-7 under the 1940 Act which, in the opinion of the Trustees of the Trust, represents the fair value of the particular security. The amortized cost of a security is determined by valuing it at original cost and thereafter assumes a constant accretion/amortization to maturity of any discount/premium. By using amortized cost valuation, the Fund seeks to maintain a constant net asset value of $1.00 per share despite minor shifts in the market value of its portfolio securities.

(a) The aggregate cost for federal income tax purposes was $235,362,677.

(b) Interest rate represents discount rate at time of purchase; not a coupon rate.

(c) Security payable on demand at par including accrued interest (usually with seven days notice). The interest rate is adjustable and is based on bank prime rates or other interest rate adjustment indices. The rate shown is the rate in effect at the date of this statement.

(d) Floating rate note. Rate shown is as of September 30, 2009.

Fair Value Measurements

In accordance with accounting standards related to fair value measurements and disclosures, the Fund has categorized the inputs utilized in determining the value of the Fund’s assets or liabilities. These inputs are summarized in the three broad levels listed below:

• Level 1 - quoted prices in active markets for identical assets or liabilities;

• Level 2 - prices determined using other significant inputs that are observable either directly, or indirectly through corroboration with observable market data (which could include quoted prices for similar assets or liabilities, interest rates, credit risk, etc.);

• Level 3 - prices determined using significant unobservable inputs for situations where quoted prices or observable inputs are unavailable such as when there is little or no market activity for an asset or liability (unobservable inputs reflect the Portfolio’s own assumptions in determining the fair value of assets or liabilities and would be based on the best information available).

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 to value the Fund’s investments as of September 30, 2009, at value:
