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 that pay interest exempt from state personal income tax. The Fund may temporarily depart from its principal investment strategies for defensive purposes.

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 exempt from requirements that permit money market funds to impose a liquidity fee and/or temporary redemption gates.

The Fund has not elected to be subject to the liquidity fees and gates requirement at this time.

The Fund will invest its assets so that at least 80% of its net assets (plus any borrowings for investment purposes) are invested in U.S. Treasury investments. The Fund will notify shareholders at least 60 days in advance of any change in its investment policy that would enable the Fund to invest, under normal circumstances, less than 80% of its net assets (plus any borrowings for investment purposes) in U.S. Treasury investments.

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 U.S. Treasury securities generally fall when interest rates rise. Interest rate changes have a greater effect on the price of U.S. Treasury securities with longer maturities.

• Risk Related to the Economy. The value of the Fund's portfolio may decline in tandem with a drop in one or more markets in which the Fund invests. Economic, political and financial conditions may, from time to time, cause the Fund to experience volatility, illiquidity, shareholder redemptions or other potentially adverse effects.

• 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.

• Regulatory Reform Risk. Changes in the laws and regulations applicable to and governing money market funds, such as Rule 2a-7 under the Investment Company Act of 1940 ("1940 Act"), can impact the Fund. On July 23, 2014, the SEC voted to amend Rule 2a-7 and other rules and forms related to money market funds. These amendments may affect the manner in which the Fund is structured and operated, as well as the Fund's expenses and returns. Compliance with many of these amendments will be required on October 14, 2016, two years after the effective date for the amendments. U.S. government money market funds are exempt from a number of the changes required by these amendments. As a result of these amendments, the Fund may be required to take certain steps that impact the Fund and the precise nature of such impact has not yet been determined.

• Technology Risk. The Adviser uses various technologies in managing the Fund, consistent with its investment objective 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 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.
