Beginning on January 1, 2021, as permitted by regulations adopted by the Securities and Exchange Commission, paper copies of the Fund's shareholder reports will no longer be sent by mail, unless you specifically request paper copies of the reports from the Fund or from your financial intermediary, such as a broker-dealer or bank. Instead, the reports will be made available on the Fund's website, and you will be notified by mail each time a report is posted and provided with a website link to access the report.
If you already elected to receive shareholder reports electronically, you will not be affected by this change and you need not take any action.

You may elect to receive all future reports in paper free of charge. If you invest through a financial intermediary, you can contact your financial intermediary to request that you continue to receive paper copies of your shareholder reports. If you invest directly with the Fund, you can call (800) 959-4246 to let the Fund know you wish to continue receiving paper copies of your shareholder reports.

Principal Investment Strategies of the Fund
The Fund invests at least 99.5% of its total assets in cash, Government Securities, and repurchase agreements collateralized by cash or Government Securities. In addition, at least 80% of the Fund’s net assets (plus any borrowings for investment purposes) will be invested, under normal circumstances, in (i) direct obligations of the U.S. Treasury, (ii) other securities issued or guaranteed as to principal and interest by the U.S. Government or its agencies and instrumentalities (agency securities) and (iii)

repurchase agreements secured by those obligations referenced in (i) and (ii) above. In contrast to the Fund’s 99.5% policy, the Fund’s 80% policy does not include cash or repurchase agreements collateralized by cash. Government Security generally means any security issued or guaranteed as to principal or interest by the U.S. Government or certain of its agencies or instrumentalities; or any certificate of deposit for any of the foregoing.
The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
The Fund is a Government Money Market Fund as defined by Rule 2a-7 under the Investment Company Act of 1940, as amended (Rule 2a-7), that seeks to maintain a stable price of $1.00 per share by using the amortized cost method to value portfolio securities and rounding the share value to the nearest cent. The Fund invests in conformity with U.S. Securities and Exchange Commission (SEC) rules and regulation requirements for money market funds for the quality, maturity, diversification and liquidity of investments. The Fund invests only in U.S. dollar-denominated securities maturing within 397 calendar days of the date of purchase, with certain exceptions permitted by applicable regulations. The Fund maintains a dollar-weighted average portfolio maturity of no more than 60 calendar days, and a dollar-weighted average portfolio maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Fund’s Board, and must be an Eligible Security.
In selecting securities for the Fund’s portfolio, the portfolio managers focus on securities that offer safety, liquidity, and a competitive yield. The Adviser conducts a credit analysis of each potential issuer prior to the purchase of its securities.
The portfolio managers normally hold portfolio securities to maturity, but may sell a security when they deem it advisable, such as when market or credit factors materially change.
Principal Risks of Investing in the Fund
You could 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. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are:
Money Market Fund Risk. Although the Fund seeks to preserve the value of your investment at $1.00 per share, you may lose money by investing in the Fund. The share price of money market funds can fall below the $1.00 share price. The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time. The credit quality of the Fund’s holdings can change rapidly in certain markets, and the default of a single holding could have an adverse impact on the Fund’s share price. The Fund’s share price can also be negatively affected during periods of high redemption pressures, illiquid markets, and/or significant market volatility. While the Board of Trustees may implement procedures to impose a fee upon the sale of your shares or temporarily suspend your ability to sell shares in the future if the Fund’s liquidity falls below required minimums because of market conditions or other factors, the Board has not elected to do so at this time. Should the Board elect to do so, such change would only become effective after shareholders were provided with specific advance notice of the change in the Fund’s policy and provided with the opportunity to redeem their shares in accordance with Rule 2a-7 before the policy change became effective.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities
that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
U.S. Government Obligations Risk. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions which are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or adverse investor sentiment generally. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
Repurchase Agreement Risk. If the seller of a repurchase agreement defaults or otherwise does not fulfill its obligations, the Fund may incur delays and losses arising from selling the underlying securities, enforcing its rights, or declining collateral value.
Yield Risk. The Fund’s yield will vary as the short-term securities in its portfolio mature or are sold and the proceeds are reinvested in other securities. When interest rates are very low, the Fund’s expenses could absorb all or a portion of the Fund’s income and yield. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. Additionally, legislative, regulatory, or tax developments may adversely affect management of the Fund and, therefore, the ability of the Fund to achieve its investment objective.

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund, the Fund’s distributor or its related companies may pay the intermediary for the sale of Fund shares and related services.
