<font style="FONT-FAMILY: Arial" size="2">We look for investments that we think will provide a high level of current income. To achieve our objective, we invest in short-term money market instruments such as obligations issued by the U.S. Government, its agencies and instrumentalities, commercial paper, asset-backed securities, funding agreements, variable rate demand notes, bills, notes and other obligations issued by banks, corporations and other companies (including trust structures), and obligations issued by foreign banks, companies or foreign governments, and municipal notes. The Fund will invest only in instruments with remaining maturities of thirteen months or less and which are denominated in U.S. dollars. The Fund may invest in longer-term securities that are accompanied by demand features which will shorten the effective maturity of the securities to 397 days or less.</font><br/><br/><font style="FONT-FAMILY: Arial" size="2">Although the Fund seeks to maintain a stable net asset value (NAV) of $1 per share, there can be no guarantee that it will always be able to do so. Additionally, you should be aware that a very small number of money market funds in other fund complexes have, in the past, "broken the buck," which means that investors did not receive $1 per share for their investment in those funds, and any money market fund may do so in the future. You should also be aware that the Fund's investment manager and its affiliates are under no obligation to provide financial support to the Fund or take other measures to ensure that you receive $1 per share for your investment in the Fund. You should not invest in the Fund with the expectation that any such action will be taken.</font>
<font style="FONT-FAMILY: Arial" size="2">All investments have risks to some degree. Please remember that an investment in the Fund 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 per share, it is possible to lose money by investing in the Fund.</font><br/><br/><font style="FONT-FAMILY: Arial" size="2"><b>Recent Market Events.</b> The equity and debt capital markets in the United States and internationally have experienced unprecedented volatility. The financial crisis has caused a significant decline in the value and liquidity of many securities. This environment could make identifying investment risks and opportunities especially difficult for the investment subadviser. These market conditions may continue or get worse. In response to the crisis, the U.S. and other governments and the Federal Reserve and certain foreign central banks have taken steps to support financial markets. The withdrawal of this support could negatively affect the value and liquidity of certain securities. In addition, legislation recently enacted in the United States calls for changes in many aspects of financial regulation. The impact of the legislation on the markets, and the practical implications for market participants, may not be known for some time. </font><br/><br/><font style="FONT-FAMILY: Arial" size="2"><b>Risk of Increase in Expenses.</b> Your actual cost of investing in the Fund may be higher than the expenses shown in the expense table for a variety of reasons. For example, expense ratios may be higher than those shown if average net assets decrease. Net assets are more likely to decrease and Fund expense ratios are more likely to increase when markets are volatile. </font><br/><br/><font style="FONT-FAMILY: Arial" size="2"><b>Debt Obligations.</b> Debt obligations are subject to credit risk, market risk and interest rate risk. The Fund's holdings, share price, yield and total return may also fluctuate in response to bond market movements. </font><br/><br/><font style="FONT-FAMILY: Arial" size="2"><b>Credit Risk.</b> This is the risk that the issuer, the guarantor or the insurer of a fixed-income security, or the counterparty to a contract, may be unable or unwilling to make timely principal and interest payments or to otherwise honor its obligations. Additionally, the securities could lose value due to a loss of confidence in the ability of the issuer, guarantor, insurer or counterparty to pay back debt. The longer the maturity and the lower the credit quality of a bond, the more sensitive it is to credit risk. </font><br/><br/><font style="FONT-FAMILY: Arial" size="2"><b>Market Risk.</b> Your investment in Fund shares represents an indirect investment in the securities owned by the Fund. The value of these securities, like other investments, may move up or down, sometimes rapidly and unpredictably. Securities markets are volatile. Your Fund shares at any point in time may be worth less than what you invested, even after taking into account the reinvestment of Fund dividends and distributions. Regardless of how well an individual investment performs, if financial markets go down, you could lose money. </font><br/><br/><font style="FONT-FAMILY: Arial" size="2"><b>Interest Rate Risk.</b> This is the risk that the securities in which the Fund invests could lose value because of interest rate changes. For example, bonds tend to decrease in value if interest rates rise. Debt obligations with longer maturities generally are more sensitive to interest rate changes. In addition, short-term and long-term interest rates do not necessarily move in the same direction or by the same amount. An instrument's reaction to interest rate changes depends on the timing of its interest and principal payments and the current interest rate for each of those time periods. Instruments with floating interest rates can be less sensitive to interest rate changes. Certain types of debt obligations are also subject to prepayment and extension risk. When interest rates fall, the issuers of debt obligations may prepay principal more quickly than expected, and the Fund may be required to reinvest the proceeds at a lower interest rate. This is referred to as "prepayment risk." When interest rates rise, debt obligations may be repaid more slowly than expected, and the value of the Fund's holdings may fall sharply. This is referred to as "extension risk." </font><br/><br/><font style="FONT-FAMILY: Arial" size="2"><b>Management Risk.</b> Actively managed mutual funds are subject to management risk. The subadviser will apply investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these techniques will produce the desired results. Additionally, the securities selected by the subadviser may underperform the markets in general, the Fund's benchmark and other mutual funds with similar investment objectives. </font><br/><br/><font style="FONT-FAMILY: Arial" size="2"><b>Redemption Risk.</b> The Fund may experience heavy redemptions, particularly during periods of declining or illiquid markets, that could cause the Fund to liquidate its assets at inopportune times or at a loss or depressed value and that could affect the Fund's ability to maintain a $1 share price. In addition, the Fund may suspend redemptions when permitted by applicable regulations. </font><br/><br/><font style="FONT-FAMILY: Arial" size="2"><b>Yield Risk.</b> The amount of income received by the Fund will go up or down depending on day-to-day variations in short-term interest rates, and when interest rates are very low the Fund's expenses could absorb all or a significant portion of the Fund's income. If interest rates increase, the Fund's yield may not increase proportionately. For example, the Fund's investment manager may discontinue any temporary voluntary fee limitation. In addition, the recent adoption of more stringent regulations governing the management of money market funds could have a negative effect on the Fund's yield. </font><br/><br/><font style="FONT-FAMILY: Arial" size="2"><b>Risks Associated with Concentration in the Banking Industry.</b> The Fund may invest a significant portion of its assets in obligations that are issued or backed by U.S. and non-U.S. banks, and thus will be more susceptible to negative events affecting the worldwide banking industry. </font><br/><br/><font style="FONT-FAMILY: Arial" size="2"><b>Amortized Cost Method.</b> There is also a risk that the market price for a security could be lower than the value attributed to the security through the amortized cost valuation procedures we follow. Such an event could affect our ability to maintain a net asset value of $1 per share. In the event that the Fund's Board were to determine that the extent of the deviation between the Fund's per share net asset value determined using amortized cost and its market-based net asset value per share may result in a material dilution or other unfair results to shareholders or potential investors, 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, including the potential suspension of redemption of Fund shares and liquidation of the Fund, as permitted under Rule 22e-3 under the Investment Company Act of 1940. </font><br/><br/><font style="FONT-FAMILY: Arial" size="2">For more information on the risks of investing in this Fund, please see<i> How the Fund Invests—Investment Risks</i> in the Prospectus and<i> Investment Risks and Considerations</i> in the SAI.</font>
