The fund is a money market fund subject to the maturity, quality, liquidity and diversification requirements of Rule 2a-7 under the Investment Company Act of 1940, as amended (1940 Act), and seeks to maintain a stable share price of $1.00. The fund is a "government money market fund," as that term is defined in Rule 2a-7, and as such will invest at least 99.5% of its total assets in securities issued or guaranteed as to principal and interest by the U.S. government or its agencies or instrumentalities, repurchase agreements collateralized fully by cash and/or government securities, and cash. Under normal circumstances, the fund will invest its assets so that at least 80% of its net assets (plus any borrowing for investment purposes) are invested in government securities and/or repurchase agreements that are collateralized fully by government securities. The securities in which the fund invests include those backed by the full faith and credit of the U.S. government, which include U.S. Treasury securities as well as securities issued by certain agencies of the U.S. government, and those that are neither insured nor guaranteed by the U.S. government. The fund invests in securities issued or guaranteed as to principal and interest by the U.S. government or its agencies or instrumentalities and seeks to enter into repurchase agreements that present minimal credit risk (and are considered 'eligible securities' as defined in Rule 2a-7 under the 1940 Act), based on an assessment by Dreyfus, a division of Mellon Investments Corporation, the fund's sub-adviser, of the counterparty's credit quality and capacity to meet its financial obligations, among other factors. Shares of the fund are intended to qualify as eligible investments for federally chartered credit unions. The fund intends to review changes in the applicable laws, rules and regulations governing eligible investments for federally chartered credit unions, and to take such action as may be necessary to ensure that shares of the fund qualify as eligible investments under the Federal Credit Union Act and the regulations thereunder. Shares of the fund, however, may or may not qualify as eligible investments for particular state-chartered credit unions. A state-chartered credit union should consult its legal counsel to determine whether the fund is a permissible investment under the laws applicable to it. An investment in the fund is not a bank account or a bank deposit. It is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency. 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's yield will fluctuate as the short-term securities in its portfolio mature or are sold and the proceeds are reinvested in securities with different interest rates. BNY Mellon Investment Adviser, Inc. and its affiliates are not required to reimburse the fund for losses, and you should not expect that BNY Mellon Investment Adviser, Inc. or its affiliates will provide financial support to the fund at any time, including during periods of market stress. The fund is subject to the following principal risks: · Interest rate risk: This risk refers to the decline in the prices of fixed-income securities that may accompany a rise in the overall level of interest rates. A sharp and unexpected rise in interest rates could impair the fund's ability to maintain a stable net asset value. A wide variety of market factors can cause interest rates to rise, including central bank monetary policy, rising inflation and changes in general economic conditions. It is difficult to predict the pace at which central banks or monetary authorities may increase (or decrease) interest rates or the timing, frequency, or magnitude of such changes. Changing interest rates may have unpredictable effects on markets, may result in heightened market volatility and may detract from fund performance. For floating and variable rate obligations, there may be a lag between an actual change in the underlying interest rate benchmark and the reset time for an interest payment of such an obligation, which could harm or benefit the fund, depending on the interest rate environment or other circumstances. · Liquidity risk: When there is little or no active trading market for specific types of securities, it can become more difficult to sell the securities in a timely manner at or near their perceived value. In such a market, the value of such securities may fall dramatically, potentially impairing the fund's ability to maintain a stable net asset value. · U.S. Treasury securities risk: A security backed by the U.S. Treasury or the full faith and credit of the United States is guaranteed only as to the timely payment of interest and principal when held to maturity, but the market prices for such securities are not guaranteed and will fluctuate. BNY Dreyfus Institutional Preferred Government Money Market Fund - Capital Summary 2 · Government securities risk: Not all obligations of the U.S. government, its agencies and instrumentalities are backed by the full faith and credit of the U.S. Treasury. Some obligations are backed only by the credit of the issuing agency or instrumentality, and in some cases there may be some risk of default by the issuer. Any guarantee by the U.S. government or its agencies or instrumentalities of a security held by the fund does not apply to the market value of such security or to shares of the fund itself. · Repurchase agreement counterparty risk: The fund is subject to the risk that a counterparty in a repurchase agreement could fail to honor the terms of the agreement. If this occurs, the fund may suffer a loss if the proceeds from the sale of the underlying securities are less than the repurchase price. · Market risk: The value of the securities in which the fund invests may be affected by political, regulatory, economic and social developments. In addition, turbulence in financial markets and reduced liquidity in fixed-income markets may negatively affect many issuers, which could adversely affect the fund. Global economies and financial markets are becoming increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers in a different country, region or financial market. These risks may be magnified if certain events or developments adversely interrupt the global supply chain; in these and other circumstances, such risks might affect companies world-wide. Local, regional or global events such as war, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, recessions, elevated levels of government debt, changes in trade regulation or economic sanctions, internal unrest and discord, or other events could have a significant impact on the fund and its investments.

BNY Dreyfus Institutional Preferred Government Money Market Fund - Capital Summary 3 The fund's Capital shares are designed generally for institutional investors, acting for themselves or in a fiduciary, advisory, agency, brokerage, custodial or similar capacity. Capital shares of the fund also may be purchased directly by individuals. In general, the fund's minimum initial investment for Capital shares is $200 million with no minimum subsequent investment, unless: (a) the investor has invested at least $200 million in the aggregate among the fund and any of the Preferred Funds, the Cash Management Funds or BNY Dreyfus Treasury and Agency Liquidity Money Market Fund; or (b) the investor has, in the opinion of BNY Institutional Services, adequate intent and availability of assets to reach a future aggregate level of investment of $200 million in such funds. You may sell (redeem) your shares on any business day by calling 1-800-373-9387 or through compatible computer systems. The fund's distributions are taxable as ordinary income or capital gains, except when your investment is through a U.S. tax-advantaged investment plan (in which case you may be taxed upon withdrawal of your investment from such account). Distributions paid by the fund may include a return of capital. The amount of the fund's distribution, if any, that constitutes a return of capital represents a return of your original investment in fund shares. The portion of any distribution treated as a return of capital will not be subject to tax currently, but will result in a corresponding reduction in your cost basis in the fund's shares. Distributions in excess of your adjusted tax basis in your fund shares are generally treated as capital gains. If you purchase shares through a broker-dealer or other financial intermediary (such as a bank), the fund's distributor and its related companies may pay the intermediary for the sale of fund shares and related services. To the extent that the intermediary may receive lesser or no payments in connection with the sale of other investments, the payments from the fund's distributor and its related companies may create a potential conflict of interest by influencing the broker-dealer or other intermediary and your financial representative to recommend the fund over the other investments. This potential conflict of interest may be addressed by policies, procedures or practices adopted by the financial intermediary. As there may be many different policies, procedures or practices adopted by different intermediaries to address the manner in which compensation is earned through the sale of investments or the provision of related services, the compensation rates and other payment arrangements that may apply to a financial intermediary and its representatives may vary by intermediary. Ask your financial representative or visit your financial intermediary's website for more information. This prospectus does not constitute an offer or solicitation in any state or jurisdiction in which, or to any person to whom, such offering or solicitation may not lawfully be made.
