Example

This example is intended to help you compare the cost of investing in the fund’s Investor Shares with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the fund’s Investor Shares for the time periods indicated and then redeem all of your shares at the end of those time periods. The example also assumes that your investment has a 5% return each year and that the Investor Shares’ operating expenses remain the same. The figures are based on total annual fund operating expenses after expense reduction. The expenses would be the same whether you stayed in the fund or sold your shares at the end of each period. Your actual costs may be higher or lower.

Principal Investment Strategies

To pursue its goal, the fund typically invests in securities backed by the full faith and credit of the U.S. government. The fund intends to operate as a government money market fund under the regulations governing money market funds. The fund will invest at least 99.5% of its total assets in cash and/or government securities; (including bills and notes); under normal circumstances, at least 80% of the fund’s net assets (including, for this purpose, any borrowings for investment purposes) will be invested solely in U.S. Treasury securities (excluding cash). With respect to the 80% policy, the fund will notify its shareholders at least 60 days before changing the policy. The full faith and credit backing is the strongest backing offered by the U.S. government, and traditionally is considered by investors to be the highest degree of safety as far as the payment of principal and interest.

Based on the fund manager’s view of market conditions for U.S. Treasury securities, the fund may invest up to 20% of its net assets in: (i) obligations that are issued by the U.S. government, its agencies or instrumentalities, including obligations that are not fully guaranteed by the U.S. Treasury, such as those issued by the Federal National Mortgage Association (Fannie Mae), the Federal Home Loan Mortgage Corporation (Freddie Mac) and the Federal Home Loan Banks; and (ii) obligations that are issued by private issuers that are guaranteed as to principal or interest by the U.S. government, its agencies or instrumentalities. Obligations that are issued by private issuers that are guaranteed as to principal or interest by the U.S. government, its agencies or instrumentalities are considered U.S. government securities under the rules that govern money market funds.

In choosing securities, the fund’s manager seeks to maximize current income within the limits of the fund’s investment objective and credit, maturity and diversification policies. By investing primarily in full faith and credit U.S. government investments, the fund seeks to provide maximum safety as to its assets. The fund is distinct from certain other types of government money market funds in that it does not invest in repurchase agreements. The portfolio manager may adjust the fund’s holdings or its average maturity based on actual or anticipated changes in credit quality or market dynamics, such as interest rates. To preserve its investors’ capital, the fund seeks to maintain a stable $1.00 share price.

Because the income from U.S. Treasury securities is exempt from state and local income taxes, the fund generally expects that the majority of the dividends it pays will be exempt from those taxes as well. (Dividends still will be subject to federal income tax.) However, the fund may invest up to 20% of its net assets in non-U.S Treasury investments that are not exempt from state and local income taxes. Further, during unusual market conditions, the fund may invest a greater portion of its assets in investments that are not exempt from state and local income taxes as a temporary defensive measure. When the fund engages in such activities, it may not achieve its investment goal.

As a government money market fund, the fund’s Board of Trustees (the Board) has determined not to subject the fund to a liquidity fee and/or a redemption gate on fund redemptions. Please note that the Board has reserved its ability to change this determination with respect to liquidity fees and/or redemption gates, but only after providing appropriate prior notice to shareholders.

Principal Risks

The fund is subject to risks, any of which could cause an investor to lose money. The fund’s principal risks include:

Investment Risk. You could lose money by investing in the fund. Although the fund seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so.  An investment in the fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The fund’s sponsor has no legal obligation to provide financial support to the fund, and you should not expect that the sponsor will provide financial support to the fund at any time.

Interest Rate Risk. Interest rates rise and fall over time. As with any investment whose yield reflects current interest rates, the fund’s yield will change over time. During periods when interest rates are low, the fund’s yield (and total return) also will be low or may even be negative, which may make it difficult for the fund to pay expenses out of fund assets or maintain a stable $1.00 share price. A change in a central bank’s monetary policy or improving economic conditions may result in an increase in interest rates. The fund is currently subject to heightened levels of interest rate risk because of the continued economic recovery, along with the fact that the Federal Reserve Board ended its quantitative easing program in 2014, and has begun, and may continue, to raise interest rates. A sudden or unpredictable rise in interest rates may cause volatility in the market and may decrease liquidity in the money market securities markets, making it more difficult for the fund to sell its money market investments at a time when the investment adviser might wish to sell such investments. Decreased market liquidity also may make it more difficult to value some or all of the fund’s money market securities holdings.

Stable Net Asset Value Risk. If the fund or another money market fund fails to maintain a stable net asset value (or such perception exists in the market place), the fund could experience increased redemptions, which may adversely impact the fund’s share price.  The fund is permitted, among other things, to reduce or withhold any income and/or gains generated from its portfolio to maintain a stable $1.00 share price.

Credit Risk. The fund is subject to the risk that a decline in the credit quality of a portfolio investment could cause the fund to lose money or underperform. The fund could lose money if the issuer of a portfolio investment fails to make timely principal or interest payments or if a guarantor, liquidity provider or counterparty of a portfolio investment fails to honor its obligations. Negative perceptions of the ability of an issuer, guarantor, liquidity provider or counterparty to make payments or otherwise honor its obligations, as applicable, could also cause the price of that investment to decline. The credit quality of the fund’s portfolio holdings can change rapidly in certain market environments and any downgrade or default on the part of a single portfolio investment could cause the fund’s share price or yield to fall.

Many of the U.S. government securities that the fund invests in are not backed by the full faith and credit of the U.S. government, which means they are neither issued nor guaranteed by the U.S. Treasury. Although maintained in conservatorship by the Federal Housing Finance Agency since September 2008, Fannie Mae and Freddie Mac maintain only lines of credit with the U.S. Treasury. The Federal Home Loan Banks maintain limited access to credit lines from the U.S. Treasury. Other securities, such as obligations issued by the Federal Farm Credit Banks Funding Corporation, are supported solely by the credit of the issuer. There can be no assurance that the U.S. government will provide financial support to securities of its agencies and instrumentalities if it is not obligated to do so under law. Also, any government guarantees on securities the fund owns do not extend to the shares of the fund itself.

Management Risk. Any actively managed mutual fund is subject to the risk that its investment adviser will select investments or allocate assets in a manner that could cause the fund to underperform or otherwise not meet its objective. The fund’s investment adviser applies its own investment techniques and risk analyses in making investment decisions for the fund, but there can be no guarantee that they will produce the desired results. The investment adviser’s maturity decisions will also affect the fund’s yield, and potentially could affect its share price. To the extent that the investment adviser anticipates interest rate trends imprecisely, the fund’s yield at times could lag the yields of other money market funds.

Redemption Risk. The fund may experience periods of heavy redemptions that could cause the fund to liquidate its assets at inopportune times or at a loss or depressed value, particularly during periods of declining or illiquid markets. Redemptions by a few large investors in the fund may have a significant adverse effect on the fund’s ability to maintain a stable $1.00 share price. In the event any money market fund fails to maintain a stable net asset value, other money market funds, including the fund, could face a market-wide risk of increased redemption pressures, potentially jeopardizing the stability of their $1.00 share prices.

Money Market Fund Risk. The fund is not designed to offer capital appreciation. In exchange for their emphasis on stability and liquidity, money market investments may offer lower long-term performance than stock or bond investments.

Performance

Because the Investor Shares have not been in operation for a year, the bar chart below shows how the investment results of the fund’s Sweep Shares have varied from year to year, and the following table shows the fund’s Sweep Shares’ average annual total returns for various periods. This information provides some indication of the risks of investing in the fund’s Investor Shares. Investor Shares and Sweep Shares of the fund would have substantially similar performance because they invest in the same portfolio of securities and the annual returns would differ only to the extent that Investor Shares have lower expenses. All figures assume distributions were reinvested. Keep in mind that future performance may differ from past performance.

[1] “Other expenses” is an estimate based on the expenses the fund’s Investor Shares expects to incur for the current fiscal year.

[2] The investment adviser and its affiliates have agreed to limit the total annual fund operating expenses (excluding interest, taxes and certain non-routine expenses) of the fund to 0.35% for so long as the investment adviser serves as the adviser to the fund (the contractual expense limitation agreement). This contractual expense limitation agreement may only be amended or terminated with the approval of the fund's Board of Trustees.
