Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 for the time periods indicated and then redeem or hold all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that operating expenses remain the same. The Example does not reflect sales charges (loads)on reinvested dividends. If these sales charges (loads) were included, your costs would be higher. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

1 Year	$59
3 Years	$186
5 Years	$324
10 Years	$726

RISK/RETURN SUMMARY: INVESTMENTS, RISKS and PERFORMANCE

What are the Fund’s Main Investment Strategies?

The Fund invests in a portfolio of U.S. Treasury securities maturing in 397 days or less and repurchase agreements collateralized fully by U.S. Treasury securities. The Fund may also hold cash.

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”).

The Fund will operate as a “government money market fund,” as such term is defined in or interpreted under Rule 2a-7 under the Investment Company Act of 1940, as amended (the “1940 Act”). “Government money market funds” are required to invest at least 99.5% of their total assets in: (i) cash; (ii) securities issued or guaranteed by the United States or certain U.S. government agencies or instrumentalities; and/or (iii) repurchase agreements that are collateralized fully. Government money market funds are not required to adopt a liquidity fee framework.

The Fund will invest its assets so that at least 80% of its net assets (plus any borrowings for investment purposes) are invested in Treasury investments. The Fund will notify shareholders at least 60 days in advance of any change in this investment policy.

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 negatively impact the Fund’s ability to maintain a stable NAV, delay the payment of redemptions by the Fund, or reduce the Fund’s daily dividends include:

■ Interest Rate Risk. Prices of fixed-income securities generally fall when interest rates rise. Recent and potential future changes in monetary policy made by central banks and/or their governments are likely to affect the level

of interest rates. Very low or negative interest rates magnify interest rate risk. During periods when interest rates are low or there are negative interest rates, the Fund’s yield (and total return) also is likely to be lower or the Fund may be unable to maintain a positive return, or yield, or a stable NAV.

■ Counterparty Risk. A party to a transaction involving the Fund may fail to meet its obligations. This could cause the Fund to lose money or to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategies.

■ Risk Associated with Investing Share Purchase Proceeds. On days during which there are net purchases of Fund Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the Fund holds cash, or if the yield of the securities purchased is less than that of the securities already in the portfolio, the Fund’s yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will likely 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.

■ Risk 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.

■ Additional Factors Affecting Yield. 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. Further, the Fund’s yield will vary. Periods of very low or negative interest rates impact, in a negative way, the Fund’s ability to maintain a positive return, or yield, or pay dividends to Fund shareholders.

■ Risk Related to the Economy. The value of the Fund’s portfolio may decline in tandem with a drop in the overall value of the markets in which the Fund invests and/or other markets. Global economic, political and financial conditions, including geopolitical and other events (e.g., wars, tensions, sanctions and terrorism), legislative changes or shifts in fiscal or monetary policy or reform, industry or economic trends and developments, grid congestion or capacity constraints, natural disasters or public health risks, such as epidemics or pandemics, may, from time to time, and for varying periods of time, have a significant effect on the economies of many nations, including the U.S., and financial markets generally and cause the Fund to experience volatility, illiquidity, loss of value, shareholder redemptions, and/or other potentially adverse effects.

■ Technology Risk. The Adviser uses various technologies in managing the Fund, consistent with its investment objective(s) and strategy described in this Prospectus. For example, proprietary and third-party data and systems are utilized to support decision making for the Fund. Data imprecision,

software or other technology malfunctions, programming inaccuracies and similar circumstances may impair the performance of these systems, which may negatively affect Fund performance.

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 a bank account and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The Fund’s sponsor is not required to reimburse the Fund for losses, and you should not expect that the sponsor will provide financial support to the Fund at any time, including during periods of market stress.
