Principal Investment Strategy

The fund pursues its investment objective by investing only in government securities (i.e., securities issued or guaranteed as to principal and interest by the U.S. government or its agencies or instrumentalities, including those with floating or variable rates of interest), repurchase agreements collateralized solely by government securities and/or cash, and cash. 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, 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 is required to 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 solely by cash and/or government securities, and cash. 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.

1


The fund seeks to invest in securities issued or guaranteed as to principal and interest by the U.S. government or its agencies or instrumentalities and enter into repurchase agreements that present minimal credit risk, based on an assessment by BNY Mellon Investment Adviser, Inc. (BNYM Investment Adviser) of the issuer's, guarantor's or counterparty's credit quality and capacity to meet its financial obligations, among other factors. As part of this assessment, to the extent relevant information is available, BNYM Investment Adviser also evaluates whether environmental, social and governance (ESG) factors could have a positive, negative or neutral impact on the entity's financial condition (including cash flows, revenues, and short-term debt coverage) and competitive positioning or reputation within the relevant sector. The relevance and significance of these ESG factors to an entity's financial condition, competitive positioning or reputation vary and are dependent on the specific sector in which an issuer, guarantor or counterparty operates.

With respect to counterparties to repurchase agreements, relevant ESG considerations may include carbon financing and exposure, privacy and data security, responsible investments, corporate governance, business ethics, and financial system stability.

As part of its credit risk analysis, BNYM Investment Adviser evaluates material ESG factors for the U.S. government and U.S. government agencies or instrumentalities. These factors are evaluated from a sovereign perspective and may include environmental risks such as natural disasters, weather patterns and climate change; social factors such as long-term demographic trends, health equality and education standards; and governance factors such as the quality of institutional frameworks. In this regard, ESG considerations are generally expected to have a neutral impact on investment decisions pertaining to securities issued or guaranteed by the U.S. government or its agencies or instrumentalities, as other factors such as the financial condition, liquidity and market positioning of such entities are expected to outweigh ESG factors.

In evaluating ESG factors, BNYM Investment Adviser considers ESG research developed by one or more of its affiliates or third parties, including ESG assessments and commentary provided by credit rating agencies, and other material ESG information as available. Identified ESG factors are incorporated within BNYM Investment Adviser's credit risk analysis to determine whether such ESG factors have a positive, negative or neutral impact on BNYM Investment Adviser's assessment of creditworthiness. Based on this determination, the fund may adjust the applicable credit or maturity limits for the relevant issuer, guarantor or counterparty. BNYM Investment Adviser, however, may determine, across all investments within the fund, that other attributes of creditworthiness, such as sources of liquidity and market positioning, outweigh ESG considerations when making an investment decision, and may not consider available ESG data in connection with every investment decision it makes on behalf of the fund. As a result, the fund may invest in securities of issuers or securities or securities guaranteed by guarantors or enter into repurchase agreements with counterparties, for example, that may be negatively impacted by ESG factors.

Principal Risks

An investment in the fund is not 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. The fund currently is not permitted to impose a fee upon the sale of fund shares (a "liquidity fee") or temporarily suspend redemptions (a redemption "gate") under distressed conditions as some other types of money market funds are, and the fund's board has no intention to impose a liquidity fee or redemption gate. Neither BNYM Investment Adviser nor its affiliates have a legal obligation to provide financial support to the fund, and you should not expect that BNYM Investment Adviser or its affiliates will provide financial support to the fund at any time. The following are the principal risks that could reduce the fund's income level and/or share price:

 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. Interest rates in the United States have been rising and may continue to increase in the near future. 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. 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.

2


 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.

 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.

 Market risk. The value of the securities in which the fund invests may be affected by political, regulatory, economic and social developments.  Events such as war, acts of terrorism, the spread of infectious illness or other public health issue, recessions, or other events could have a significant impact on the fund and its investments. Recent examples include pandemic risks related to COVID-19 and aggressive measures taken world-wide in response by governments, including closing borders, restricting international and domestic travel, and the imposition of prolonged quarantines of large populations, and by businesses, including changes to operations and reducing staff.

 ESG evaluation risk. As part of BNYM Investment Adviser's assessment of an issuer's, guarantor's or counterparty's credit quality and capacity to meet its financial obligations, the consideration of ESG factors may contribute to the fund making different investments than funds that invest in money market securities but do not incorporate ESG considerations when selecting investments. Under certain economic conditions, this could cause the fund to underperform funds that do not incorporate ESG considerations. For example, the incorporation of ESG considerations may result in the fund forgoing opportunities to buy certain securities when it might otherwise be advantageous to do so or selling securities when it might otherwise be disadvantageous for the fund to do so. The incorporation of ESG considerations may also affect the fund's exposure to certain sectors and/or types of investments, which may adversely impact the fund's performance depending on whether such sectors or investments are in or out of favor in the market. BNYM Investment Adviser's security selection process incorporates ESG data provided by affiliated and unaffiliated data providers, which may be limited for certain issuers, guarantors and repurchase agreement counterparties and/or only take into account one or a few ESG related components. In addition, ESG data may include quantitative and/or qualitative measures, and consideration of this data may be subjective. Different methodologies may be used by the various data sources that provide ESG data for issuers, guarantors and counterparties, including the issuers, guarantors and counterparties themselves. ESG data from data providers used by BNYM Investment Adviser often lack standardization, consistency and transparency, and, for certain issuers, guarantors and counterparties, such data, including ESG ratings and scores, may not be available, complete or accurate. BNYM Investment Adviser's evaluation of ESG factors relevant to the financial condition or risk profile of a particular issuer or guarantor of securities or repurchase agreement counterparty, or otherwise, may be adversely affected in such instances. As a result, the fund's investments may differ from, and potentially underperform, funds that incorporate ESG data from other sources or utilize other methodologies.

Performance

The following bar chart and table provide some indication of the risks of investing in the fund. The bar chart shows changes in the performance of the fund's Institutional shares from year to year. The table shows the average annual total returns of the fund's Institutional shares over time. The fund's past performance is not necessarily an indication of how the fund will perform in the future. More recent performance information may be available at www.dreyfus.com.

The historical performance of the fund's Institutional shares, which are not offered in this prospectus, is shown in the bar chart and table since past performance information for a full calendar year is not available for BOLD® shares as of the date of this prospectus. Each share class is invested in the same portfolio of securities, and the annual returns would have differed only to the extent that the classes have different expenses. Accordingly, although BOLD® shares are estimated to have the same or lower total annual expense ratio to that of Institutional shares, to the extent BOLD® shares were to have a higher total annual expense ratio than Institutional shares, the performance shown for BOLD® shares would be lower.

The fund's BOLD® shares are designed for institutional investors, acting for themselves or in a fiduciary, advisory, agency, brokerage, custodial or similar capacity. BOLD® shares of the fund also may be purchased by individuals. Investors are required to purchase BOLD® shares through certain affiliates of BNYM Investment Adviser.

Tax Information

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).

Payments to Broker-Dealers and Other Financial Intermediaries

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.

Fund Details

Goal and Approach

The fund seeks as high a level of current income as is consistent with the preservation of capital and the maintenance of liquidity. The fund pursues its investment objective by investing only in government securities (i.e., securities issued or guaranteed as to principal and interest by the U.S. government or its agencies or instrumentalities, including those with floating or variable rates of interest), repurchase agreements collateralized solely by government securities and/or cash, and cash.

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, 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 is required to 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 solely by cash and/or government securities, and cash. Under normal conditions, Dreyfus Government Cash Management 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. Dreyfus Government Cash Management will notify shareholders at least 60 days in advance of any change in this investment policy. The securities in which the fund invests include those backed by the full faith and credit of the U.S. government and those that are neither insured nor guaranteed by the U.S. government. Securities backed by the full faith and credit of the U.S. government include U.S. Treasury securities as well as securities issued by certain agencies of the U.S. government, such as the Government National Mortgage Association. The repurchase agreements in which the fund may invest may include tri-party repurchase agreements executed through a third party bank that provides payment administration, collateral custody and management services to the parties to the repurchase agreements.

Among other requirements, the fund is required to hold at least 30% of its assets in cash, U.S. Treasury securities, certain other government securities with remaining maturities of 60 days or less, or securities that can readily be converted into cash within five business days. In addition, the fund is required to hold at least 10% of its assets in cash, U.S. Treasury securities or securities that can readily be converted into cash within one business day. The fund must maintain an average dollar-weighted portfolio maturity of 60 days or less and a maximum weighted average life to maturity of 120 days.

The fund seeks to invest in securities issued or guaranteed as to principal and interest by the U.S. government or its agencies or instrumentalities and enter into repurchase agreements that present minimal credit risk, based on BNYM Investment Adviser's assessment of the issuer's, guarantor's or counterparty's credit quality and capacity to meet its financial obligations, among other factors. As part of this assessment, to the extent relevant information is available, BNYM Investment Adviser also evaluates whether environmental, social and governance (ESG) factors could have a positive, negative or neutral impact on the entity's financial condition (including cash flows, revenues, and short-term debt coverage) and competitive positioning or reputation within the relevant sector. The relevance and significance of these ESG factors to an entity's financial condition, competitive positioning or reputation vary and are dependent on the specific sector in which an issuer, guarantor or counterparty operates.

With respect to issuers or guarantors of securities or counterparties to repurchase agreements, relevant ESG considerations may include carbon financing and exposure, privacy and data security, responsible investments, corporate governance, business ethics, and financial system stability. Repurchase agreement counterparties are evaluated for material ESG risks regardless of the agreement's underlying collateral.

As part of its credit risk analysis, BNYM Investment Adviser evaluates material ESG factors for the U.S. government and U.S. government agencies or instrumentalities. These factors are evaluated from a sovereign perspective and may include environmental risks such as natural disasters, weather patterns and climate change; social factors such as long-term demographic trends, health equality and education standards; and governance factors such as the quality of institutional frameworks. In this regard, ESG considerations are generally expected to have a neutral impact on investment decisions pertaining to securities issued or guaranteed by the U.S. government or its agencies or

6


instrumentalities, as other factors such as the financial condition, liquidity and market positioning of such entities are expected to outweigh ESG factors.

In evaluating ESG factors, BNYM Investment Adviser considers ESG research developed by one or more of its affiliates or third parties, including ESG assessments and commentary provided by credit rating agencies, and other material ESG information as available. The scope of such ESG research may vary significantly depending on the issuer, guarantor or counterparty and may be limited or unavailable. Identified ESG factors are incorporated within BNYM Investment Adviser's credit risk analysis to determine whether such ESG factors have a positive, negative or neutral impact on BNYM Investment Adviser's assessment of creditworthiness. Based on this determination, the fund may adjust the applicable credit or maturity limits for the relevant issuer, guarantor or counterparty. BNYM Investment Adviser, however, may determine, across all investments within the fund, that other attributes of creditworthiness, such as sources of liquidity and market positioning, outweigh ESG considerations when making an investment decision, and may not consider available ESG data in connection with every investment decision it makes on behalf of the fund. As a result, the fund may invest in securities of issuers or securities guaranteed by guarantors or enter into repurchase agreements with counterparties, for example, that may be negatively impacted by ESG factors.

In response to liquidity needs or unusual market conditions, the fund may hold all or a significant portion of its total assets in cash for temporary defensive purposes. This may result in a lower current yield and prevent the fund from achieving its investment objective.

Investment Risks

An investment in the fund is not a bank deposit. It is not insured or guaranteed by the 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. The fund currently is not permitted to impose a fee upon the sale of fund shares (a "liquidity fee") or temporarily suspend redemptions (a redemption "gate") under distressed conditions as some other types of money market funds are, and the fund's board has no intention to impose a liquidity fee or redemption gate. Neither BNYM Investment Adviser nor its affiliates have a legal obligation to provide financial support to the fund, and you should not expect that BNYM Investment Adviser or its affiliates will provide financial support to the fund at any time. The following are the principal risks that could reduce the fund's income level and/or share price:

 Interest rate risk. Prices of fixed-income securities tend to move inversely with changes in interest rates. Interest rate 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. Interest rates in the United States have been rising and may continue to increase in the near future. 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. A low interest rate environment may prevent the fund from providing a positive yield or paying fund expenses out of fund assets and impair the fund's ability to maintain a stable net asset value. Changing interest rates may have unpredictable effects on markets, may result in heightened market volatility and may detract from fund performance. In such an interest rate environment, the fund may be subject to a greater risk of principal decline from rising interest rates. 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. In a rising interest rate environment, for example, a floating or variable rate obligation that does not reset immediately would prevent the fund from taking full advantage of the rising interest rates in a timely manner. However, in a declining interest rate environment, the fund may benefit from a lag due to an obligation's interest rate payment not being immediately impacted by a decline in interest rates.

 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. To meet redemption requests, the fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions, which may impair 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. In addition, such guarantees do not extend to shares of the fund itself. Because U.S. Treasury securities trade actively outside the United States, their prices may rise and fall as changes in global economic conditions affect the demand for these securities.

7


 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. 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. In addition, because many types of U.S. government securities trade actively outside the United States, their prices may rise and fall as changes in global economic conditions affect the demand for these securities.

 Repurchase agreement counterparty risk. The fund is subject to the risk that a counterparty in a repurchase agreement and/or, for a tri-party repurchase agreement, the third party bank providing payment administration, collateral custody and management services for the transaction, could fail to honor the terms of the agreement.

 Market risk. The value of the securities in which the fund invests may be affected by political, regulatory, economic and social developments.  Events such as war, acts of terrorism, the spread of infectious illness or other public health issue, recessions, or other events could have a significant impact on the fund and its investments.  Recent examples include pandemic risks related to COVID-19 and aggressive measures taken world-wide in response by governments, including closing borders, restricting international and domestic travel, and the imposition of prolonged quarantines of large populations, and by businesses, including changes to operations and reducing staff. The COVID-19 pandemic has had, and any other outbreak of an infectious disease or other serious public health concern could have, a significant negative impact on economic and market conditions and could trigger a prolonged period of global economic slowdown.

 ESG evaluation risk. As part of BNYM Investment Adviser's assessment of an issuer's, guarantor's or counterparty's credit quality and capacity to meet its financial obligations, the consideration of ESG factors may contribute to the fund making different investments than funds that invest in money market securities but do not incorporate ESG considerations when selecting investments. Under certain economic conditions, this could cause the fund to underperform funds that do not incorporate ESG considerations. For example, the incorporation of ESG considerations may result in the fund forgoing opportunities to buy certain securities when it might otherwise be advantageous to do so or selling securities when it might otherwise be disadvantageous for the fund to do so. The incorporation of ESG considerations may also affect the fund's exposure to certain sectors and/or types of investments, which may adversely impact the fund's performance depending on whether such sectors or investments are in or out of favor in the market. BNYM Investment Adviser's security selection process incorporates ESG data provided by affiliated and unaffiliated data providers, which may be limited for certain issuers, guarantors and repurchase agreement counterparties and/or only take into account one or a few ESG related components.

BNYM Investment Adviser's evaluation of ESG factors relevant to the financial condition or risk profile of a particular issuer or guarantor of securities or repurchase agreement counterparty, or otherwise, may be adversely affected in such instances.

Management

The fund is managed by Dreyfus, a division of BNY Mellon Investment Adviser, Inc., the fund's investment adviser, 240 Greenwich Street, New York, New York 10286.

For the fiscal year ended January 31, 2023, the fund paid BNYM Investment Adviser a management fee at the effective annual rate set forth in the table below.

BNYM Investment Adviser will make an annual donation, out of its own legitimate profits, to select HBCUs of an amount representing 10% of its net revenue attributable to the fund's BOLD® shares, subject to a minimum annual donation amount of $300,000. "Net revenue" represents the management fee paid by the fund to BNYM Investment Adviser after any fee waivers and/or expense reimbursements by BNYM Investment Adviser and less any revenue sharing payments made by BNYM Investment Adviser or its affiliates, with respect to the fund's BOLD® shares. If in any year 10% of net revenue attributable to the fund's BOLD® shares is less than $300,000, BNYM Investment Adviser nevertheless will make the donation of the minimum amount from its own legitimate profits. Donations are made annually after the end of the fund's fiscal year. BNYM Investment Adviser maintains the option to increase, decrease or terminate this donation in its sole discretion at any time. From time to time, one or more affiliates of BNYM Investment Adviser may contribute to BNYM Investment Adviser's annual donation to HBCUs. HBCUs are "Historically Black Colleges and Universities," which are defined by the Higher Education Act of 1965, as amended, as: "…any historically black college or university that was established prior to 1964, whose principal mission was, and is, the education of black Americans, and that is accredited by a nationally recognized accrediting agency or association determined by the Secretary of Education to be a reliable authority as to the quality of training offered or is, according to such an agency or association, making reasonable progress toward accreditation."

This approach is designed to provide each fund with a distinct, stable identity.

BNY Mellon Securities Corporation (BNYMSC), a wholly-owned subsidiary of BNYM Investment Adviser, serves as distributor of the fund and of the other funds in the BNY Mellon Family of Funds. BNYM Investment Adviser or BNYMSC may provide cash payments out of its own resources to financial intermediaries that sell shares of funds in the BNY Mellon Family of Funds or provide other services. Such payments are separate from any fees or other expenses that may be paid by a fund to those financial intermediaries. Because those payments are not made by fund shareholders or the fund, the fund's total expense ratio will not be affected by any such payments. These payments may be made to financial intermediaries, including affiliates, that provide shareholder servicing, sub-administration, recordkeeping and/or sub-transfer agency services, marketing support and/or access to sales meetings, sales representatives and management representatives of the financial intermediary. Cash compensation also may be paid from BNYM Investment Adviser's or BNYMSC's own resources to financial intermediaries for inclusion of a fund on a sales list, including a preferred or select sales list or in other sales programs. These payments sometimes are referred to as "revenue sharing." From time to time, BNYM Investment Adviser or BNYMSC also may provide cash or non-cash compensation to financial intermediaries or their representatives in the form of occasional gifts; occasional meals, tickets or other entertainment; support for due diligence trips; educational conference sponsorships; support for recognition programs; technology or infrastructure support; and other forms of cash or non-cash compensation permissible under broker-dealer regulations. In some cases, these payments or compensation may create an incentive for a financial intermediary or its employees to recommend or sell shares of the fund to you. This potential conflict of interest may be addressed by policies, procedures or practices that are 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. Please contact your financial representative for details about any payments they or their firm may receive in connection with the sale of fund shares or the provision of services to the fund.

The fund, BNYM Investment Adviser and BNYMSC have each adopted a code of ethics that permits its personnel, subject to such code, to invest in securities, including securities that may be purchased or held by the fund. Each code of ethics restricts the personal securities transactions of employees, and requires portfolio managers and other investment personnel to comply with the code's preclearance and disclosure procedures. The primary purpose of the

9


respective codes is to ensure that personal trading by employees is done in a manner that does not disadvantage the fund or other client accounts.

Shareholder Guide

Buying and Selling Shares

This prospectus offers BOLD® shares. "BOLD" is an acronym for Black Opportunity for Learning and Development. The fund's BOLD® shares are designed generally for institutional investors, acting for themselves or in a fiduciary, advisory, agency, brokerage, custodial or similar capacity. BOLD® shares of the fund also may be purchased directly by individuals. Generally, each investor will be required to open a single master account with the fund for all purposes. In certain cases, the fund may request investors to maintain separate master accounts for shares held by the investor (i) for its own account, for the account of other institutions and for accounts for which the institution acts as a fiduciary, and (ii) for accounts for which the investor acts in some other capacity. An institution may arrange with the fund's transfer agent for sub-accounting services and will be charged directly for the cost of such services. Institutions purchasing BOLD® shares for the benefit of their clients may impose policies, limitations and fees which are different from those described in this prospectus. The fund offers other classes of shares, which are described in separate prospectuses. Institutions purchasing fund shares on behalf of their clients determine which class is suitable for their clients.

Investors are required to purchase BOLD® shares through certain affiliates of BNYM Investment Adviser. For information on how to purchase BOLD® shares, please contact a BNY Mellon Institutional Services representative by calling 1-800-346-3621.

HBCUs that receive an annual donation from BNYM Investment Adviser or its affiliates are able to invest in BOLD® shares of the fund. HBCUs will not participate in, or have any influence on, the day-to-day operations of the fund or management of the fund.

Your price for BOLD® shares is the net asset value (NAV) per share.

The fund's portfolio securities are valued at amortized cost, which does not take into account unrealized gains or losses. As a result, portfolio securities are valued at their acquisition cost, adjusted over time based on the discounts or premiums reflected in their purchase price. The fund uses this valuation method pursuant to Rule 2a-7 under the Investment Company Act of 1940, as amended, in order to be able to maintain a price of $1.00 per share.

When calculating its NAV, the fund compares the NAV using amortized cost to its NAV using available market quotations or market equivalents, which generally are provided by an independent pricing service approved by the fund's board. The pricing service's procedures are reviewed under the general supervision of the board.

How to Buy Shares

The fund's NAV is calculated on any day the New York Stock Exchange (NYSE) is open. In addition, the fund's NAV will be calculated on any day the NYSE is closed but the Federal Reserve Bank is open and the Securities Industry and Financial Markets Association (SIFMA) recommends that fixed income securities markets be open for the day or a portion of the day.

The time at which the fund's NAV is calculated, and the trading deadline for orders "in proper form" (as defined below), is reflected in the table below. The fund reserves the right to change the time at which the fund's NAV is calculated and the trading deadline to an earlier time than stated below in the case of an emergency, if regular trading on the NYSE is restricted or closes early, the fixed income securities markets or the Federal Reserve Bank close early, or as otherwise permitted by the Securities and Exchange Commission.

Fund Calculation of NAV/Trading Deadline for Orders in Proper Form

Dreyfus Government Cash Management

5:00 p.m.

All times are Eastern time.

Orders in proper form received and accepted by the fund or a financial intermediary that serves as agent for the fund by the time of day at which the fund calculates its NAV will become effective at the NAV determined on that day and

11


shares purchased will receive the dividend declared on that day. An order to purchase shares received by the fund will be deemed to be "in proper form" if the fund receives "federal funds" or other immediately available funds promptly thereafter. Unless other arrangements have been agreed in advance, the fund generally expects to receive the funds within two hours after the order is received by the fund or a financial intermediary that serves as agent for the fund, or by 6:00 p.m., Eastern time, whichever is earlier. Orders submitted through a financial intermediary that does not serve as an agent for the fund are priced at the fund's NAV next calculated after the fund receives the order in proper form from the intermediary and accepts it, which may not occur on the day the order is submitted to the intermediary.

An order in proper form received and accepted after the time of day at which the fund determines its NAV will be priced at the NAV determined on the following business day and will begin to accrue dividends on such business day. If payment is not received within the appropriate time period, the fund reserves the right to cancel the purchase order at its discretion, and the investor would be liable for any resulting losses or expenses incurred by the fund or the fund's transfer agent, including interest charges.

By Wire. To open an account by wire, or purchase additional shares, please contact a BNY Mellon Institutional Services representative by calling 1-800-346-3621 for more information.

By Computer. You may input new account data and retrieve an account number for your records by accessing The Lion Remote System. Be sure to print a report of transactions for your records. Please contact the BNY Mellon Institutional Services by calling 1-800-346-3621 for more information about The Lion Remote System or any other compatible computerized trading system.

The minimum initial investment in BOLD® shares is $50,000,000, with no minimum subsequent investment, unless: (a) the investor is certified by a federal, state or local government agency as a minority owned business and makes an investment, or has, in the opinion of BNY Mellon Institutional Services, adequate intent and availability of assets to reach a future aggregate level of investment, of $1,000,000 in BOLD® shares; or (b) the investor has invested, or has, in the opinion of BNY Mellon Institutional Services, adequate intent and availability of assets to reach a future aggregate level of investment of, at least $50,000,000 among the fund and (i) any of the Cash Management Funds, which currently include Dreyfus Cash Management, Dreyfus Government Cash Management, Dreyfus Government Securities Cash Management, Dreyfus Tax Exempt Cash Management, Dreyfus Treasury Obligations Cash Management and Dreyfus Treasury Securities Cash Management; (ii) any of the Preferred Funds, which currently include Dreyfus Institutional Preferred Government Money Market Fund, Dreyfus Institutional Preferred Treasury Obligations Fund, Dreyfus Institutional Preferred Treasury Securities Money Market Fund and Dreyfus Institutional Preferred Money Market Fund or (iii) Dreyfus Treasury and Agency Liquidity Money Market Fund.

How to Sell Shares

You may sell (redeem) shares at any time by telephone or compatible computer facility.

Your shares will be priced at the next determined NAV. If a request for redemption is received and accepted by the time of day at which the fund determines its NAV, the proceeds of the redemption ordinarily will be transmitted by wire in federal funds on the same day, and the shares will not receive the dividend declared on that day. Under certain circumstances (i.e., during periods of stressed market conditions or in cases of very large redemption requests), however, the fund may pay a portion or all of the redemption proceeds on the next business day. If the request is received and accepted after the time of day at which the fund determines its NAV, or is transmitted through the National Securities Clearing Corporation, the shares will receive the dividend declared on that day, and the proceeds of redemption ordinarily will be transmitted by wire in federal funds on the next business day.

The processing of redemptions may be suspended, and the delivery of redemption proceeds may only be delayed by more than one business day, for any period: (i) during which the NYSE is closed (other than on holidays or weekends), or during which trading on the NYSE is restricted; (ii) when an emergency exists that makes the disposal of securities owned by the fund or the determination of the fair value of the fund's net assets not reasonably practicable; or (iii) as permitted by order of the Securities and Exchange Commission for the protection of fund shareholders. For these purposes, the Securities and Exchange Commission determines the conditions under which trading shall be deemed to be restricted and an emergency shall be deemed to exist.

Under normal circumstances, the fund expects to meet redemption requests by using cash it holds in its portfolio or selling portfolio securities to generate cash. In addition, pursuant to an interfund lending order granted by the Securities and Exchange Commission, the fund and certain other money market funds in the BNY Mellon Family of Funds may borrow money from certain money market funds in the BNY Mellon Family of Funds for temporary or emergency purposes to meet redemption requests.

The fund also reserves the right to pay redemption proceeds in securities rather than cash (i.e., "redeem in-kind"), if the amount redeemed is large enough to affect fund operations or the redemption request is during stressed market

12


conditions. Investors are urged to call BNY Mellon Institutional Services before effecting any large transactions. Securities distributed in connection with any such redemption in-kind are expected to generally represent the investor's pro rata portion of assets held by the fund immediately prior to the redemption, with adjustments as may be necessary in connection with, for example, restricted securities, odd lots or fractional shares. Any securities distributed in-kind will remain exposed to market risk until sold, and you may incur taxable gain when selling the securities.

By Telephone. You may redeem shares by calling a BNY Mellon Institutional Services representative at 1-800-346-3621 to provide information about your transaction. Be sure the fund has your bank account information on file. Proceeds will be wired to your bank.

By Computer. You may redeem shares by accessing The Lion Remote System, or by other electronic means approved by BNY Mellon Institutional Services, to select from multiple wire instructions. Be sure to confirm your bank account information and print a report of the transaction for your records.

General Policies

The fund and the fund's transfer agent are authorized to act on telephone or online instructions from any person representing himself or herself to be you and reasonably believed by the fund or the transfer agent to be genuine. You may be responsible for any fraudulent telephone or online order as long as the fund or the fund's transfer agent (as applicable) takes reasonable measures to confirm that the instructions are genuine.

Money market funds generally are used by investors for short-term investments, often in place of bank checking or savings accounts, or for cash management purposes. Investors value the ability to add and withdraw their funds quickly, without restriction. For this reason, although BNYM Investment Adviser discourages excessive trading and other abusive trading practices, the fund has not adopted policies and procedures, or imposed redemption fees or other restrictions such as minimum holding periods, to deter frequent purchases and redemptions of fund shares. BNYM Investment Adviser also believes that money market funds, such as the fund, are not typically targets of abusive trading practices. However, frequent purchases and redemptions of the fund's shares could increase the fund's transaction costs, such as market spreads and custodial fees, and may interfere with the efficient management of the fund's portfolio, which could detract from the fund's performance. The fund reserves the right to reject any purchase request in whole or in part. Funds in the BNY Mellon Family of Funds that are not money market mutual funds have approved policies and procedures that are intended to discourage and prevent abusive trading practices in those mutual funds.

The fund also reserves the right to change its minimum investment amount.

The fund also may process purchase and sale orders and calculate its NAV on days that the fund's primary trading markets are open and the fund's management determines to do so.

Escheatment

If your account is deemed "abandoned" or "unclaimed" under state law, the fund may be required to "escheat" or transfer the assets in your account to the applicable state's unclaimed property administration. The state may sell escheated shares and, if you subsequently seek to reclaim your proceeds of liquidation from the state, you may only be able to recover the amount received when the shares were sold. It is your responsibility to ensure that you maintain a correct address for your account, keep your account active by contacting the fund's transfer agent or distributor by mail or telephone or accessing your account through the fund's website at least once a year, and promptly cash all checks for dividends, capital gains and redemptions. The fund, the fund's transfer agent and BNYM Investment Adviser and its affiliates will not be liable to shareholders or their representatives for good faith compliance with state escheatment laws.

Distributions and Taxes

The fund earns dividends, interest and other income from its investments, and distributes this income (less expenses) to shareholders as dividends. The fund also realizes capital gains from its investments, and distributes these gains (less any losses) to shareholders as capital gain distributions. The fund ordinarily declares dividends from its net investment income on each day its NAV is calculated and normally pays dividends monthly and capital gain distributions, if any, annually. Fund dividends and capital gain distributions will be reinvested in the fund unless you instruct the fund otherwise. There are no fees or sales charges imposed by the fund on reinvestments.

The fund's distributions are taxable as ordinary income or capital gains (unless you are investing through a U.S. tax-advantaged investment plan, in which case taxes may be deferred).

The tax status of any distribution generally is the same regardless of how long you have been in the fund and whether you reinvest your distributions or take them in cash.

13


The tax status of your distributions will be detailed in your annual tax statement from the fund. Because everyone's tax situation is unique, please consult your tax adviser before investing.

Services for Fund Investors

Account Statements

Every investor in the fund in the BNY Mellon Family of Funds automatically receives regular account statements. Each investor will also be sent a yearly statement detailing the tax characteristics of any dividends and distributions the investor has received.

Financial Highlights

These financial highlights describe the performance of the fund's Institutional shares and BOLD® shares for the fiscal periods indicated. "Total return" shows how much your investment in the fund would have increased (or decreased) during each period, assuming you had reinvested all dividends and distributions. These financial highlights have been derived from the fund's financial statements, which have been audited by Ernst & Young LLP, an independent registered public accounting firm, whose report, along with the fund's financial statements, is included in the fund's annual report, which is available upon request. As BOLD® shares are a new class of the fund, financial highlights information is available for BOLD® shares for less than a full fiscal year.
