Principal Investment Strategies

The Fund seeks to attain its objective by investing in short-term money-market securities denominated in U.S. dollars that are of high quality and present minimal credit risks. Under the current management policies, the Fund invests only in the following types of obligations:

(1) Obligations issued or guaranteed by the U.S. government or its agencies or instrumentalities.

(2) Bank obligations and instruments secured by them. (“Banks” include commercial banks, savings banks and savings and loan associations; they include foreign banks and foreign branches of United States banks.)

(3) Short-term corporate debt known as “commercial paper.”

(4) Corporate debt obligations (for example, bonds and debentures). Debentures are a form of unsecured corporate debt.

(5) Variable amount master demand notes which are repayable on not more than 30 days’ notice.

(6) Repurchase agreements.

(7) Refunded Securities are debt securities the principal and interest of which are paid by “Government Securities” (as defined in the Investment Company Act of 1940 as amended (the “1940 Act”)) that have been placed in an escrow account and pledged only to the payment of the debt security. In general, Government Securities are those the principal and interest of which are paid by or are guaranteed by the U.S. Government or its instrumentalities.  The Fund will invest only in Refunded Securities meeting the applicable requirements of Rule 5b-3 under the 1940 Act.

The Fund seeks to maintain a net asset value of $1.00 per share. Under applicable regulations, it is subject to related maturity, quality, diversification and liquidity requirements.

Principal Risks

An investment in the Fund is not a deposit in, nor endorsed or guaranteed by, any bank, and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the Fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the Fund.

Because variable amount master demand notes are direct lending arrangements between the lender and borrower, it is not generally contemplated that they will be traded, and there is no secondary market for them. Variable amount master demand notes repayable in more than seven days are securities which are not readily marketable, and fall within the Fund’s limitation on securities which are illiquid. These notes are also subject to credit risk.

Repurchase agreements involve some risk to the Fund if the other party does not fulfill its obligations under the agreement.

The value of money-market instruments tends to fall if prevailing interest rates rise.

Corporate bonds and debentures are subject to interest rate and credit risks.

There are two types of risk associated with the Fund:  interest rate risk and credit risk.

*Interest rate risk relates to fluctuations in market value arising from changes in interest rates. If interest rates rise, the value of debt securities will normally decline. All fixed-rate debt securities, even the most highly rated, are subject to interest rate risk.

*Credit risk relates to the ability of the particular issuers of the obligations the Fund owns to make periodic interest payments as scheduled and ultimately repay principal at maturity.

Investments in foreign banks and foreign branches of United States banks involve certain risks. Foreign banks and foreign branches of domestic banks may not be subject to regulations that meet U.S. standards. Investments in foreign banks and foreign branches of domestic banks may also be subject to other risks, including future political and economic developments, the possible imposition of withholding taxes on interest income, the seizure or nationalization of foreign deposits and the establishment of exchange controls or other restrictions.
