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	$101
3 Years	$315
5 Years	$547
10 Years	$1,213

RISK/RETURN SUMMARY: INVESTMENTS, RISKS and PERFORMANCE

What are the Fund’s Main Investment Strategies?

The Fund invests primarily in a portfolio of high-quality, tax-exempt securities maturing in 397 days or less. The Fund generally seeks to invest its assets so that distributions of annual interest income are exempt from federal regular income tax. Interest from the Fund’s investments may be subject to the federal alternative minimum tax for individuals (AMT).

Tax-exempt securities are fixed-income securities that, in the opinion of bond counsel to the issuer or on the basis of another authority believed by the Fund’s investment adviser (the “Adviser”) to be reliable, pay interest that is not subject to federal regular income taxes. The types of securities in which the Fund may principally invest include: (a) tax-exempt securities such as the following types, some of which may be subject to credit enhancement: variable rate demand instruments, municipal notes, general obligation bonds, special revenue bonds, private activity bonds and tax-exempt commercial paper; and (b) interests in securities of other investment companies.

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 Adviser may invest in securities subject to AMT in an attempt to seek appropriate risk-adjusted returns and provide diversification.

Under normal circumstances, the Fund will invest its assets so that at least 80% of the income that it distributes will be exempt from federal regular income tax. This policy may not be changed without shareholder approval.

In addition, in response to unusual circumstances, such as adverse market, economic or other conditions (for example, to help avoid potential losses, or during periods when there is a shortage of appropriate tax-exempt securities), to maintain liquidity to meet shareholder redemptions, or to accommodate cash inflows, the Adviser may also leave a portion of the Fund’s assets uninvested, or may invest in securities subject to federal income tax.

What are the Main Risks of Investing in the Fund?

Pursuant to Rule 2a-7 the Fund is designated as a “retail” money market fund and is permitted to use amortized cost to value its portfolio securities and to transact at a stable $1.00 net asset value. As a retail money market fund, the Fund has adopted policies and procedures reasonably designed to limit investments in the Fund to accounts beneficially owned by natural persons.

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:

■ Tax-Exempt Securities Risk. The securities in which the Fund invests may include those issued by state or local governments, other political subdivisions or authorities, or directly or indirectly supported by taxes, assessments, tolls, fees or other revenue collected by or otherwise derived from or through such issuers. Special factors, such as legislative changes, and state and local economic and business developments, may adversely affect the yield and/or value of the Fund’s investments in tax-exempt securities. Changes in tax policy could adversely affect the tax-exempt status of securities held by the Fund.

■ Issuer Credit Risk. It is possible that interest or principal on securities will not be paid when due. Money market funds try to minimize this risk by purchasing higher-quality securities.

■ 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 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.

■ Liquidity Fees Risk. Pursuant to Rule 2a-7, the Fund may impose discretionary liquidity fees on redemptions subject to a determination by the Fund’s Board, or its delegate, that such a liquidity fee is in the Fund’s best interests. Such determination will be based on current market conditions and the Fund’s particular circumstances, and it is expected that such fee would be imposed, if at all, during periods of extraordinary market stress. If the Fund’s Board, including a majority of the Independent Trustees, or its delegate, determines that imposing a liquidity fee is in the Fund’s best interests, the Fund will impose a discretionary liquidity fee not to exceed 2% of the value of the shares redeemed. The discretionary liquidity fee would be applied to all Fund redemptions and would remain in effect until the Fund’s Board, or its delegate, determines that the fee is no longer in the Fund’s best interests. If the Fund imposes a liquidity fee, depending on how the redemption order is communicated, the proceeds delivered may be for an amount that is less than the original redemption.

■ Interest Rate Risk. Prices of fixed-income securities (including tax-exempt 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.

■ Call Risk. The Fund’s performance may be adversely affected by the possibility that an issuer of a security held by the Fund may redeem the security prior to maturity at a price below or above its current market value.

■ Sector Risk. A substantial part of the Fund’s portfolio may be comprised of securities issued or credit enhanced by businesses with similar characteristics or by issuers located in the same state. As a result, the Fund will be more susceptible to any economic, business, political or other developments which generally affect these issuers or entities.

■ Tax Risk. In order to be tax exempt, tax-exempt securities must meet certain legal requirements. Failure to meet such requirements may cause the interest received and distributed by the Fund to shareholders to be taxable. The Fund and the Adviser will rely on the opinions of issuers’ bond counsel on the tax-exempt status of interest on municipal bonds. The Fund and the Adviser do not guarantee or represent that such opinions are correct when issued or that underlying facts and circumstances will not change such that such opinions remain correct, and the Fund and the Adviser will not undertake independent investigations to review the bases for or ongoing effect of those tax opinions. Income from tax-exempt securities held by the Fund could also become taxable because of changes in tax laws or interpretations by taxing authorities, resulting in a higher tax liability for shareholders and potentially

adversely impacting Fund performance. The Fund may invest in securities whose interest is subject to state tax, federal regular income tax or AMT. Consult your tax professional for more information.

■ Liquidity Risk. Liquidity risk is the risk that the Fund will experience significant net redemptions of Fund Shares at a time when it cannot find willing buyers for its portfolio securities or can only sell its portfolio securities at a material loss.

■ Credit Enhancement Risk. The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). If the credit quality of the credit enhancement provider (for example, a bank or bond insurer) is downgraded, a security credit enhanced by such credit enhancement provider also may be downgraded. Having multiple securities credit enhanced by the same enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such an enhancement provider. Adverse developments in the banking or bond insurance industries also may negatively affect the Fund, as the Fund may invest in securities credit enhanced by banks or by bond insurers without limit.

■ 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 yield of the securities purchased is less than that of the securities already in the Fund’s portfolio, or if the Fund holds cash, 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.

■ 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. The Fund may impose a fee upon the sale of your shares. 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.
