RISK/RETURN SUMMARY: INVESTMENTS, RISKS and PERFORMANCE

What are the Fund's Main Investment Strategies?

The Fund invests primarily in a portfolio of short-term, high-quality, fixed-income securities issued by banks, corporations and the U.S. government.

Certain of the government securities in which the Fund invests are not backed by the full faith and credit of the U.S. government, such as those issued by the Federal Home Loan Mortgage Corporation (“Freddie Mac”), the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Bank System. These entities are, however, supported through federal subsidies, loans or other benefits. The Fund may also invest in government securities that are supported by the full faith and credit of the U.S. government, such as those issued by the Government National Mortgage Association (“Ginnie Mae”). Finally, the Fund may invest in a few government securities that have no explicit financial support, but which are regarded as having implied support because the federal government sponsors their activities.

In pursuing its investment objective and implementing its investment strategies, the Fund will comply with Rule 2a-7 under the Investment Company Act of 1940 (“Rule 2a-7”).

What are the Main Risks of Investing in the Fund?

All mutual funds take investment risks. Therefore, even though the Fund is a money market fund that seeks to maintain a stable NAV, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund's returns include:

Issuer Credit Risk. There is a possibility that issuers of securities in which the Fund may invest may default on the payment of interest or principal on the securities when due, which would cause the Fund to lose money.
Counterparty Credit Risk. A party to a transaction involving the Fund may fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategies.

Interest Rate Risk. Prices of fixed-income securities generally fall when interest rates rise. Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities.
Sector Risk. A substantial part of the Fund's portfolio may be comprised of securities issued by companies in the financial services industry. As a result, the Fund will be more susceptible to any economic, business, political or other developments which generally affect these companies.
Credit Enhancement Risk. The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). If the credit quality of the credit enhancement provider (for example, a bank) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded. Having multiple securities credit enhanced by the same credit enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such a credit enhancement provider.
Risks of Foreign Investing. Because the Fund invests in securities issued by foreign companies, the Fund may be more affected by foreign economic and political conditions, taxation policies and accounting and auditing standards than would otherwise be the case.
Prepayment Risk. The Fund may invest in asset-backed and mortgage-backed securities, which may be subject to prepayment risk. If interest rates fall, and unscheduled prepayments on such securities accelerate, the Fund will be required to reinvest the proceeds at the lower interest rates then available.
Risks Associated with Investing Share Purchase Proceeds. On days where there are net purchases of Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the yield of the securities purchased is less than that of the securities already in the Fund's portfolio, or if the Fund holds cash, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.
Risks Associated with use of Amortized Cost. In the unlikely event that the Fund's Board of Trustees (“Board”) were to determine pursuant to Rule 2a-7 that the extent of the deviation between the Fund's amortized cost per Share and its market-based NAV per Share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce to the extent practicable such dilution or unfair results.
Changing Distribution Levels Risks. There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation.

The Shares offered by this Prospectus are not deposits or obligations of any bank, are not endorsed or guaranteed by any bank and are not insured or guaranteed by the U.S. government, the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.
