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. An investment in the fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Money funds have experienced significant pressures from shareholder redemptions, issuer credit downgrades, illiquid markets, and historically low yields on the securities they can hold. There have been a very small number of money funds in other fund complexes that have &#8220;broken the buck,&#8221; which means that those funds&#8217; investors did not receive $1.00 per share for their investment in those funds. You should be aware that the fund&#8217;s investment adviser is under no obligation to provide financial support to the fund or take other measures to ensure that you receive $1.00 per share for your investment in the fund. The fund&#8217;s primary risk is interest rate risk. The principal risks of investing in the fund are summarized as follows:</font><br/><br/><font style="font-family: serif; font-size: 10pt; "><font style="FONT-STYLE: italic; FONT-FAMILY: Serif; FONT-WEIGHT: bold">Credit risk</font> This is the risk that an issuer of a debt security could suffer an adverse change in financial condition that results in a payment default, security downgrade, or inability to meet a financial obligation. The fund should have relatively low credit risk because Rule 2a-7 under the Investment Company Act of 1940 requires that money funds invest in securities rated in the two highest short-term credit rating categories and because the fund invests only in securities backed by the U.S. government and other investments involving such securities. However, the credit quality of the securities held by the fund may change rapidly in certain market environments.</font><br/><br/><font style="font-family: serif; font-size: 10pt; "><font style="FONT-STYLE: italic; FONT-FAMILY: Serif; FONT-WEIGHT: bold">Interest rate risk </font>This is the risk that a decline in interest rates will lower a fund&#8217;s yield, or that a rise in the overall level of interest rates will cause a decline in the prices of fixed income securities held by a fund. The fund&#8217;s yield will vary; it is not fixed for a specific period like the yield on a bank certificate of deposit. This is a disadvantage when interest rates are falling because the fund would have to reinvest at lower interest rates. During periods of extremely low or negative short-term interest rates, the fund may not be able to maintain a positive yield or yields on par with historical levels. In addition, the adoption of more stringent regulations governing the management of money funds could have a negative effect on the fund&#8217;s yield. Finally, the fund&#8217;s investment adviser may discontinue its voluntary waiver of the fund&#8217;s management fee at any time, which could also negatively affect the fund&#8217;s yield.</font><br/><br/><font style="font-family: serif; font-size: 10pt; "><font style="FONT-STYLE: italic; FONT-FAMILY: Serif; FONT-WEIGHT: bold">Liquidity risk </font>This is the risk that the fund may not be able to sell a holding in a timely manner at a desired price. The fund may experience heavy redemptions, particularly during periods of declining or illiquid markets, which could cause the fund to liquidate its assets at inopportune times or at a depressed value and affect the fund&#8217;s ability to maintain a $1.00 share price. In addition, the fund may suspend redemptions when permitted by applicable regulations.</font><br/><br/><font style="font-family: serif; font-size: 10pt; "><font style="FONT-STYLE: italic; FONT-FAMILY: Serif; FONT-WEIGHT: bold">Repurchase agreement risk </font>This is the risk that a counterparty to a repurchase agreement becomes insolvent or fails to repurchase securities from the fund as required, which could increase the fund&#8217;s costs or prevent the fund from immediately accessing its collateral.</font> 0 20 0.0044 141 0.0134 0.0001 0.0151 0.0136 2006-12-31 0.0115 <b><font style="font-family: serif; font-size: 10pt; ">Worst Quarter</font></b> 2011-12-31 <font style="font-family: serif; font-size: 10pt; ">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.</font> <font style="font-family: sans-serif; color: rgb(0, 79, 124); font-size: 9.5pt; "><b>Investment Objective</b></font> <font style="font-family: sans-serif; color: rgb(0, 79, 124); font-size: 9.5pt; "><b>Investments, Risks, and Performance</b></font><br/><br/><font style="FONT-FAMILY: Sans-Serif; FONT-SIZE: 9.5pt;"><b>Principal Investment Strategies</b></font> <font style="font-family: serif; font-size: 10pt; ">As with any mutual fund, there is no guarantee that the fund will achieve its objective.
