reporting purposes.

Various inputs are used in determining the value of the fund's investments relating to fair value measurements.

These inputs are summarized in the three broad levels listed below.

Level 1 - unadjusted quoted prices in active markets for identical investments.

Level 2 - other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.) Level 3 - significant unobservable inputs (including 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. For example, money market securities are valued using amortized cost, in accordance with rules under the Investment Company Act of 1940. Generally, amortized cost approximates the current fair value of a security, but since the value is not obtained from a unadjusted quoted price in an active market, such securities are reflected as Level 2.

The following is a summary of the inputs used as of November 30, 2009 in valuing the fund's investments:

Valuation Inputs	Short-Term Investments ($)+
Level 1 - Unadjusted Quoted Prices	-
Level 2 - Other Significant Observable Inputs	264,929,411
Level 3 - Significant Unobservable Inputs	-
Total	264,929,411

+ See Statement of Investments for additional detailed categorizations.

The Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) has become the exclusive reference of authoritative U.S. generally accepted accounting principles (“GAAP”) recognized by the FASB to be applied by nongovernmental entities. Rules and interpretive releases of the Securities and Exchange Commission (“SEC”) under authority of federal laws are also sources of authoritative GAAP for SEC registrants. The ASC has superseded all existing non-SEC accounting and reporting standards. The fund’s financial statements are prepared in accordance with GAAP, which may require the use of management estimates and assumptions. Actual results could differ from those estimates.

It is the portfolio’s policy to maintain a continuous net asset value per share of $1.00; the portfolio has adopted certain investment, portfolio valuation and dividend and distribution policies to enable it to do so. There is no assurance, however, that the portfolio will be able to maintain a stable net asset value per share of $1.00.

Portfolio valuation: Investments in securities are valued at amortized cost in accordance with Rule 2a-7 of the Act, which has been determined by the Board of Trustees to represent the fair value of the portfolio’s investments.

Repurchase agreements: The funds may engage in repurchase agreement transactions. Under the terms of a typical repurchase agreement, a fund, through its custodian and sub-custodian, takes possession of an underlying debt obligation subject to an obligation of the seller to repurchase, and the fund to resell, the obligation at an agreed upon price and time, thereby determining the yield during the fund’s holding period. This arrangement results in a fixed rate of return that is not subject to market fluctuations during the fund’s holding period. The value of the collateral is at least equal, at all times, to the total amount of the repurchase obligation, including interest. In the event of a counterparty default, the fund has the right to use the collateral to offset losses incurred.

There is potential loss to the fund in the event the fund is delayed or prevented from exercising its rights to dispose of the collateral securities, including the risk of a possible decline in the value of the underlying securities during the period while the fund seeks to assert its rights. The Investment Adviser reviews the value of the collateral and the creditworthiness of those banks and dealers with which the fund enters into repurchase agreements to evaluate potential risks.

Additional investment related disclosures are hereby incorporated by reference to the annual and semi-annual reports previously filed with the Securities and Exchange Commission on Form N-CSR.
