Fund Summary

The fund seeks as high a level of current income as is consistent with the preservation of capital.

This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and examples below.

^* The fund's investment adviser, BNY Mellon Investment Adviser, Inc., has contractually agreed, until at least March 31, 2026, to waive receipt of its fees and/or assume the direct expenses of the fund's Service shares so that the direct expenses of the fund's Service shares (excluding taxes, brokerage commissions and extraordinary expenses) do not exceed 1.00%. To the extent that it is necessary for BNY Mellon Investment Adviser, Inc. to waive receipt of its management fee or reimburse the fund's common expenses, the amount of the waiver or reimbursement will be applied equally to each share class of the fund. On or after March 31, 2026, BNY Mellon Investment Adviser, Inc. may terminate the expense limitation agreement at any time.

Example

The 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 in the fund for the time periods indicated and then hold or redeem 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 the fund's operating expenses remain the same. The one-year example and the first year of the three-, five- and ten-years examples are based on net operating expenses, which reflect the expense limitation agreement by BNY Mellon Investment Adviser, Inc. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

To pursue its goal, the fund normally invests in a diversified portfolio of high quality, short-term, dollar-denominated debt securities, including: securities issued or guaranteed as to principal and interest by the U.S. government or its agencies or instrumentalities; certificates of deposit, time deposits, bankers' acceptances and other short-term securities issued by domestic or foreign banks or thrifts or their subsidiaries or branches; repurchase agreements, including tri-party repurchase agreements; asset-backed securities; domestic and dollar-denominated foreign commercial paper and other short-term corporate obligations, including those with floating or variable rates of interest; and dollar-denominated obligations issued or guaranteed by one or more foreign governments or any of their political subdivisions

or agencies. The fund's investments are concentrated in the banking industry, because the fund normally invests at least 25% of its net assets in domestic or dollar-denominated foreign bank obligations.

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 seeks to invest in securities and enter into repurchase agreements that present minimal credit risk, based on an assessment by Dreyfus, a division of Mellon Investments Corporation (Dreyfus), the fund's sub-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, Dreyfus 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.

As part of its credit risk analysis, Dreyfus 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, Dreyfus 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 Dreyfus's credit risk analysis to determine whether such ESG factors have a positive, negative or neutral impact on Dreyfus'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. Dreyfus, 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.

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 may impose a fee upon the sale of your shares. 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 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. 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.

2

· Credit risk: Failure of an issuer of a security to make timely interest or principal payments when due, or a decline or perception of a decline in the credit quality of the security, can cause the security's price to fall. Although the fund invests only in high quality debt securities, the credit quality of the securities held by the fund can change rapidly in certain market environments, and the default or a significant price decline of a single holding could impair the fund's ability to maintain a stable net asset value.

· Liquidity fee risk: The fund may impose a discretionary liquidity fee upon the redemption of fund shares if such a fee is determined to be in the best interests of the fund. The fund's board has delegated to Dreyfus the responsibility to make liquidity fee determinations pursuant to board-approved written guidelines. If a discretionary liquidity fee is imposed by the fund, it would reduce the amount a redeeming shareholder would receive upon the sale of fund shares during the period the fee is in effect. If the fund imposes a discretionary liquidity fee, it is possible that it may return the fee to shareholders in the form of a distribution at a later time.

· Banking industry risk: The risks generally associated with concentrating investments (i.e., hold 25% or more of its total assets) in the banking industry include interest rate risk, credit risk, and regulatory developments relating to the banking industry. Banks may be particularly susceptible to certain economic factors such as interest rate changes, adverse developments in the real estate market, fiscal and monetary policy and general economic cycles. An adverse development in the banking industry (domestic or foreign) may affect the value of the fund's investments more than if such investments were not concentrated in the banking industry.

· Foreign investment risk: The risks generally associated with dollar-denominated foreign investments include economic and political developments, seizure or nationalization of deposits, imposition of taxes or other restrictions on payment of principal and interest. The imposition of sanctions, confiscations, trade restrictions (including tariffs) and other government restrictions by the United States and other governments, or from problems in share registration, settlement or custody, may also result in losses. In addition, the fund will be subject to the risk that an issuer of foreign sovereign debt or the government authorities that control the repayment of the debt may be unable or unwilling to repay the principal or interest when due.

· 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 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.

· Asset-backed securities risk: Asset-backed securities are subject to credit, prepayment and extension risk, and may be more volatile, less liquid and more difficult to price accurately than more traditional debt securities. General downturns in the economy could cause the value of asset-backed securities to fall. Asset-backed securities are often subject to more rapid repayment than their stated maturity date would indicate as a result of the pass-through of prepayments of principal on the underlying loans.

· 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 Dreyfus'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. Dreyfus'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 Dreyfus 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. Dreyfus'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.

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 Service shares from year to year. The table shows the average annual total returns of the fund's Service 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 fund's investment adviser is BNY Mellon Investment Adviser, Inc. (BNYM Investment Adviser). BNYM Investment Adviser has engaged its affiliate, Dreyfus, a division of Mellon Investments Corporation, to serve as the fund's sub-adviser.

Investments in the fund are limited to accounts beneficially owned by natural persons. The fund's Service shares are available to investors who purchase fund shares through a third party, such as a bank, broker-dealer or financial adviser.

In general, the minimum initial investment for the fund's Service shares is $1,000 and the minimum subsequent investment is $1.00. You may sell (redeem) your shares on any business day by calling 1-800-373-9387 (inside the U.S. only) or by visiting www.dreyfus.com. If you invested in the fund through a third party, such as a bank, broker-dealer or financial adviser, or through a Retirement Plan (as defined below), you may mail your request to sell shares to BNY Institutional Services, P.O. Box 534442, Pittsburgh, Pennsylvania, 15253-4442.

Retirement Plans include qualified or non-qualified employee benefit plans, such as 401(k), 403(b)(7), Keogh, pension, profit-sharing and other deferred compensation plans, whether established by corporations, partnerships, sole proprietorships, non-profit entities, trade or labor unions, or state and local governments, but do not include IRAs (including, without limitation, traditional IRAs, Roth IRAs, Coverdell Education Savings Accounts, IRA "Rollover Accounts" or IRAs set up under Simplified Employee Pension Plans (SEP-IRAs), Salary Reduction Simplified Employee Pension Plans (SARSEPs) or Savings Incentive Match Plans for Employees (SIMPLE IRAs)).

The fund's distributions are taxable as ordinary income or capital gains, except when your investment is through an IRA, Retirement Plan or other U.S. tax-advantaged investment plan (in which case you may be taxed upon withdrawal of your investment from such account).

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

The fund seeks as high a level of current income as is consistent with the preservation of capital.

To pursue its goal, the fund normally invests in a diversified portfolio of high quality, short-term, dollar-denominated debt securities, including:

· securities issued or guaranteed as to principal and interest by the U.S. government or its agencies or instrumentalities

· certificates of deposit, time deposits, bankers' acceptances and other short-term securities issued by domestic or foreign banks or thrifts or their subsidiaries or branches

· repurchase agreements, including tri-party repurchase agreements

· asset-backed securities

· domestic and dollar-denominated foreign commercial paper, and other short-term corporate obligations, including those with floating or variable rates of interest

· dollar-denominated obligations issued or guaranteed by one or more foreign governments or any of their political subdivisions or agencies

The fund's investments are concentrated in the banking industry, because the fund normally invests at least 25% of its net assets in domestic or dollar-denominated foreign bank obligations.

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 has been designated as a "retail money market fund" (Retail Fund). As a Retail Fund, investments in the fund are limited to accounts beneficially owned by natural persons. A Retail Fund's board (or its delegate) is permitted to impose a liquidity fee (of up to 2%) on redemptions from the Retail Fund, if the board (or its delegate) determines that it is in the best interests of the fund to do so.

Among other requirements, the fund is required to invest (as measured at acquisition) at least 50% 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 invest (as measured at acquisition) at least 25% of its assets in cash, U.S. Treasury securities or securities that can readily be converted into a 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.

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.

The fund seeks to invest in securities and enter into repurchase agreements that present minimal credit risk, based on Dreyfus'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, Dreyfus 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, Dreyfus 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, Dreyfus 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 Dreyfus's credit risk analysis to determine whether such ESG factors have a positive, negative or neutral impact on Dreyfus'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. Dreyfus, however, may determine, across all investments within a 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.

More information about the fund's portfolio securities and investment techniques, and associated risks, is provided in the fund's Statement of Additional Information.

An investment in the fund is not a bank account or 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 may impose a fee upon the sale of your shares. 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. BNYM Investment Adviser and its affiliates are not required to reimburse the fund for losses, and you should not expect that BNYM Investment Adviser or its affiliates will provide financial support to the fund at any time, including during periods of market stress. 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.  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.  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. Liquidity risk also may refer to the risk that the fund will not be able to pay redemption proceeds within the allowable time period stated in this prospectus because of unusual market conditions, an unusually high volume of redemption requests, or other reasons. 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.

7

· 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.

· Credit risk: Failure of an issuer of a security to make timely interest or principal payments when due, or a decline or perception of a decline in the credit quality of the security, can cause the security's price to fall, lowering the value of the fund's investment in such security. Although the fund invests only in high quality debt securities, any of the fund's holdings could have its credit rating downgraded or could default. The credit quality and prices of the securities held by the fund can change rapidly in certain market environments, and the default or a significant price decline of a single holding could impair the fund's ability to maintain a stable net asset value.

· Liquidity fee risk: The fund may impose a discretionary liquidity fee upon the redemption of fund shares if such a fee is determined to be in the best interests of the fund. The fund's board has delegated to Dreyfus the responsibility to make liquidity fee determinations pursuant to board-approved written guidelines. If a discretionary liquidity fee is imposed by the fund, it would reduce the amount a redeeming shareholder would receive upon the sale of fund shares during the period the fee is in effect. If the fund imposes a discretionary liquidity fee, it is possible that it may return the fee to shareholders in the form of a distribution at a later time.

· ESG evaluation risk: As part of Dreyfus'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. Dreyfus'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 Dreyfus 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. Dreyfus'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.

· Banking industry risk: The risks generally associated with concentrating investments (i.e., hold 25% or more of its total assets) in the banking industry include interest rate risk, credit risk, and regulatory developments relating to the banking industry such as extensive governmental regulation and/or nationalization that affects the scope of their activities, the prices they can charge and the amount of capital they must maintain; adverse effects on profitability due to increases in interest rates or loan losses; severe price competition; and increased inter-industry consolidation and competition. An adverse development in the banking industry (domestic or foreign) may affect the value of the fund's investments more than if such investments were not invested to such a degree in the banking industry. Banks may be particularly susceptible to certain economic factors such as interest rate changes, adverse developments in the real estate market, fiscal, regulatory and monetary policy and general economic cycles. For example, deteriorating economic and business conditions can disproportionately impact companies in the banking industry due to increased defaults on payments by borrowers. Moreover, political and regulatory changes can affect the operations and financial results of companies in the banking industry, potentially imposing additional costs and expenses or restricting the types of business activities of these companies.

· Foreign investment risk: The risks generally associated with dollar-denominated foreign investments include economic and political developments, seizure or nationalization of deposits, imposition of taxes or other restrictions on payment of principal and interest.  The imposition of sanctions, confiscations, trade restrictions (including tariffs) and other

8

government restrictions by the United States and other governments, or from problems in share registration, settlement or custody, may also result in losses. Investments by the fund in foreign securities, whether issued by a foreign government, bank, corporation or other issuer, may present a greater degree of risk than investments in securities of domestic issuers because of less publicly-available financial and other information, more or less securities regulation, potential imposition of foreign withholding and other taxes, war, expropriation or other adverse governmental actions. Foreign banks and their foreign branches are not regulated by U.S. banking authorities, and generally are not bound by the accounting, auditing and financial reporting standards applicable to U.S. banks. The legal remedies for investors may be more limited than the remedies available in the United States. In addition, changes in the exchange rate of a foreign currency relative to the U.S. dollar (e.g., weakening of the currency against the U.S. dollar) may adversely affect the ability of a foreign issuer to pay interest and repay principal on an obligation. In addition, the fund will be subject to the risk that an issuer of foreign sovereign debt or the government authorities that control the repayment of the debt may be unable or unwilling to repay the principal or interest when due.

· 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.

· 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.

· 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.

· Asset-backed securities risk: Asset-backed securities are subject to credit, prepayment and extension risk, and may be more volatile, less liquid and more difficult to price accurately than more traditional debt securities. General downturns in the economy could cause the value of asset-backed securities to fall. Asset-backed securities are often subject to more rapid repayment than their stated maturity date would indicate as a result of the pass-through of prepayments of principal on the underlying loans. During periods of declining interest rates, prepayment of loans underlying asset-backed securities can be expected to accelerate. Accordingly, the fund's ability to maintain positions in such securities will be affected by reductions in the principal amount of such securities resulting from prepayments, and its ability to reinvest the returns of principal at comparable yields is subject to generally prevailing interest rates at that time. The value of some asset-backed securities may be particularly sensitive to changes in prevailing interest rates.

Investment Adviser

The fund's investment adviser is BNY Mellon Investment Adviser, Inc., 240 Greenwich Street, New York, New York 10286.

A discussion regarding the basis for the board's approving the fund's management agreement with BNYM Investment Adviser is available in the fund's Form N-CSR for the six-month period ended May 31, 2024.

Sub-Adviser

BNYM Investment Adviser has engaged its affiliate, Dreyfus, to serve as the fund's sub-adviser, pursuant to a sub-investment advisory agreement between BNYM Investment Adviser and Dreyfus. Dreyfus, subject to BNYM Investment Adviser's supervision and approval, provides investment advisory assistance and research and the day-to-day management of the fund's assets.  Dreyfus is a division of Mellon Investments Corporation, a registered investment adviser and an indirect wholly-owned subsidiary of BNY, with its principal office located at One Boston Place, 15th Floor, Boston, MA 02108.  As of December 31, 2024, Mellon Investments Corporation had approximately $912.8 billion of assets under management, which includes approximately $414.0 billion in assets managed by investment personnel of Mellon Investments Corporation acting in their capacity as officers of affiliated entities (including BNYM Investment Adviser) and the Dreyfus division of Mellon Investments Corporation.  

A discussion regarding the basis for the board's approving the sub-investment advisory agreement between BNYM Investment Adviser and Dreyfus is available in the fund's Form N-CSR report for the six-month period ended May 31, 2024.

Distributor

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. Any shareholder services fees are paid to BNYMSC for providing shareholder account service and maintenance. 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 shareholder services fees or other expenses that may be paid by the 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.

Service shares of the fund are subject to an annual shareholder services plan fee of .25% payable to the fund's distributor in respect of the provision of personal services to shareholders, such as answering shareholder inquiries regarding the fund, and/or the maintenance of shareholder accounts. Service shares are subject to an annual administrative services plan fee of .55% payable to the fund's distributor in respect of the provision of recordkeeping and other related services. The fund's distributor may pay financial intermediaries from the fees it receives under the shareholder services plan and/or administrative services plan for the provision of such services by the financial intermediaries to their clients who are beneficial owners of Service shares of the fund.

The fund, BNYM Investment Adviser, Dreyfus 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

10

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

The fund's Service shares are available to investors who purchase shares through a third party such as a bank, broker-dealer or financial adviser, or through a Retirement Plan. Third parties who open fund accounts on behalf of their clients may impose policies, limitations and fees which are different than those described herein. The fund offers other classes of shares, which are described in separate prospectuses. Third parties purchasing fund shares on behalf of their clients determine which class of shares is suitable for their clients. Consult a representative of your financial institution or Retirement Plan, if applicable, for further information.

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 net asset value (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.

Investments in the fund are limited to accounts beneficially owned by natural persons (i.e., human beings).

As a "retail" money market fund, the fund has adopted policies and procedures reasonably designed to limit all beneficial owners of the fund to natural persons. Natural persons may invest in the fund directly, jointly with other natural persons or through certain tax-advantaged savings accounts, trusts and other retirement and investment accounts, which may include, among others: participant-directed defined contribution plans; IRAs; custodial accounts; deferred compensation plans for government or tax-exempt organization employees; medical savings accounts; college savings plans; health savings account plans; ordinary trusts and estates of natural persons; or certain other retirement and investment accounts with ultimate investment authority held by the natural person beneficial owner, notwithstanding having an institutional decision maker making day to day decisions (e.g., a plan sponsor in certain retirement arrangements or an investment adviser managing discretionary investment accounts). If a shareholder account is identified as potentially not being beneficially owned by a natural person, and it cannot be established that the shareholder can be re-categorized, the shareholder will be contacted and requested to redeem its fund shares. If the shareholder is not responsive and/or does not redeem the shares as requested (typically within five business days of the request), the shares will be redeemed at the initiation of the fund. The fund and its agents will not be responsible for any loss in an investor's account or tax liability resulting from an involuntary redemption.

Financial intermediaries are required, to the extent that they hold investments in the fund, to ensure compliance of such investments with the terms and conditions for investor eligibility as set forth above. Such financial intermediaries will be expected to have policies and procedures that are reasonably designed to limit all beneficial owners of the fund on behalf of whom they place purchase orders to natural persons. The fund may involuntarily redeem shares held through intermediaries that do not assist the fund so that the fund may conclude that such shares are beneficially owned by natural persons. Financial intermediaries must promptly report to the fund the identification of any beneficial owner of shares of the fund that is not a natural person of which they are aware and promptly take steps to redeem any such shares of the fund.

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. In the event the NYSE and fixed income securities markets are closed but the Federal Reserve Bank is open, the fund may, but is not required to, calculate its NAV and accept purchase and redemption requests.

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

12

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.

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 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 to 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. An order in proper form received and accepted after the time of day at which the fund calculates its NAV will be priced, and will begin to accrue dividends, on the following business day.

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. Intermediaries are responsible for transmitting accepted orders and payments to the transfer agent within the time period agreed upon by them and will set times by which orders and payments must be received by them from their clients.

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.

For the fund's Service shares, the minimum initial and subsequent investment for regular accounts generally is $1,000 and $1.00, respectively. The minimum initial investment for Retirement Plans or IRAs (other than Coverdell Education Savings Accounts) sponsored by BNYM Investment Adviser or its affiliates is $750, with no minimum subsequent investment. The minimum initial investment for Coverdell Education Savings Accounts sponsored by BNYM Investment Adviser or its affiliates is $500, with no minimum subsequent investment. Subsequent investments made through TeleTransfer are subject to a $100 minimum and a $150,000 maximum. All investments must be in U.S. dollars. Third-party checks, cash, travelers' checks or money orders will not be accepted. You may be charged a fee for any check that does not clear.

Automatically. You may purchase additional shares by selecting one of the automatic investment services if made available by your financial institution or Retirement Plan. See "Services for Fund Investors-Automatic Services."

How to Sell Shares

You may sell (redeem) shares at any time. Your shares will be sold at the next NAV calculated after your order is received in proper form by the fund or a financial intermediary that serves as agent for the fund. 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.

If a request for redemption is received and accepted by the fund's transfer agent or other authorized entity by the time of day at which the fund determines its NAV, the proceeds of the redemption, if transfer by wire is requested, 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. If you request the fund to transmit your redemption proceeds to you by check, the fund expects that your redemption proceeds normally will be sent within two business days after your request is received in proper form. If you request the fund to transmit your redemption proceeds to you by wire via the Wire Redemption Privilege ($1,000 minimum) or electronic check via the TeleTransfer Privilege ($500 minimum), and the fund has your bank account information on file, the fund expects that your redemption proceeds normally will be wired within one business day or sent by electronic check within two business days, as applicable, to your bank account after your request is received in proper form. See "Services for Fund Investors — Wire Redemption and TeleTransfer Privileges" for more information. Payment of redemption proceeds may take longer than the number of days the fund typically expects and may take up to seven days after your order is received in proper form by the fund's transfer agent or other authorized entity, particularly during periods of stressed market conditions or very large redemptions or excessive trading.

The processing of redemptions may be suspended, and the delivery of redemption proceeds may be delayed beyond seven days, depending on the circumstances, 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.

Before selling or writing a check against shares recently purchased by check, TeleTransfer or Automatic Asset Builder, please note that:

· if you send a written request to sell such shares, the fund may delay sending the proceeds for up to eight business days following the purchase of those shares or until the fund receives verification of clearance of the funds used to purchase such shares, whichever is earlier

· the fund will not honor redemption checks, or process wire, telephone, online or TeleTransfer redemption requests for up to eight business days following the purchase of those shares or until the fund receives verification of clearance of the funds used to purchase such shares, whichever is earlier

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 conditions. Investors are urged to call BNY 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 Mail - Regular Accounts. To redeem shares in a regular account by mail, send a letter of instruction that includes your name, your account number, the name of the fund, the dollar amount to be redeemed and how and where to send the proceeds. Mail your request to the appropriate address below.

By Mail - IRA Accounts. To redeem shares in an IRA account by mail, send a letter of instruction that includes all of the same information for regular accounts and indicate whether the distribution is qualified or premature and whether the 10% TEFRA should be withheld. Mail your request to the appropriate address below.

Mailing Address. To redeem shares through a third party, such as a bank, broker-dealer or financial adviser, or in a Retirement Plan, mail to:

BNY Institutional Services
P.O. Box 534442
Pittsburgh, Pennsylvania 15253-4442

A medallion signature guarantee is required for some written sell orders. These include:

· amounts of $10,000 or more on accounts whose address has been changed within the last 30 days

· requests to send the proceeds to a different payee or address

· amounts of $100,000 or more

A medallion signature guarantee helps protect against fraud. You can obtain one from most banks or securities dealers, but not from a notary public. For joint accounts, each signature must be guaranteed. Please call to ensure that your medallion signature guarantee will be processed correctly.

Telephone or Online. To redeem shares by telephone or online, call 1-800-373-9387 (inside the U.S. only) or, for regular accounts, visit www.dreyfus.com to request your transaction.

By calling 1-800-373-9387 (inside the U.S. only), you may speak to a BNY representative and request that redemption proceeds be paid by check and mailed to your address of record (maximum $250,000 per day). For redemption requests made online through www.dreyfus.com or through the Express voice-activated account access system, there is a $100,000 per day limit.

Automatically. You may sell shares in a regular account by completing an Automatic Withdrawal Form which you can obtain by contacting your financial representative. For instructions on how to establish automatic withdrawals to sell shares in an IRA account, please call 1-800-373-9387 (inside the U.S. only) or contact your financial representative. See "Services for Fund Investors – Automatic Services."

Liquidity Fees on Fund Redemptions. Under Rule 2a-7, the fund's board (or its delegate) is permitted to impose a liquidity fee on redemptions (up to 2%) from the fund, if the board (or its delegate) determines that it is in the best interests of the fund to do so. The fund's board has delegated to Dreyfus the responsibility to make liquidity fee determinations pursuant to board-approved written guidelines. Dreyfus generally expects that a liquidity fee would be imposed, if at all, during periods of extraordinary market stress. While Dreyfus may, in its discretion, impose a liquidity fee at any time, Dreyfus generally expects that a liquidity fee would be imposed, if at all, as of the beginning of the next business day following the announcement that the fund has imposed the liquidity fee.

If Dreyfus determines that a liquidity fee is in the best interests of the fund, the fund will promptly notify fund shareholders through a supplement to the fund's summary prospectus and prospectus and will disclose the imposition of the liquidity fee on the fund's website at www.dreyfus.com. Unprocessed purchase orders that the fund received prior to notification of the imposition of a liquidity fee will be cancelled unless re-confirmed. Under certain circumstances, the fund may honor or pay redemptions without adding a liquidity fee to the redemption amount (or effect an exchange without imposing a liquidity fee) if the fund can verify that the redemption or exchange order was submitted to an intermediary that serves as agent for the fund or the fund's transfer agent before the fund imposed a liquidity fee.

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. In addition, neither the fund nor the fund's transfer agent will be responsible for any account losses because of fraud if the fund or the fund's transfer agent (as applicable) reasonably believes that the person transacting business on your account is authorized to do so. Please take precautions to protect yourself from fraud. Keep your account information private, and immediately review any fund account statements that you receive. It is important that you contact the fund immediately about any transactions or changes to your account that you believe to be unauthorized.

All shareholder services and privileges offered to shareholders may be modified or terminated at any time, except as otherwise stated in the funds' Statement of Additional Information (SAI). Please see the funds' SAI for additional information on buying and selling shares, privileges and other shareholder services.

If you invest through a financial intermediary (rather than directly through a fund), the policies may be different than those described herein. For example, banks, brokers, Retirement Plans, financial advisers and financial supermarkets

15

may charge transaction fees and may set different minimum investments or limitations on buying or selling shares. Please consult your financial representative.

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 or exchange 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, which may apply to exchanges from or into a fund. If you plan to exchange your fund shares for shares of another fund in the BNY Mellon Family of Funds, please read the prospectus of that other fund for more information.

The fund also reserves the right to:

·  change or discontinue fund exchanges, or temporarily suspend exchanges during unusual market conditions

·  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. Small Account Policy

Low balance accounts may be subject to a small account fee or to redemption, as described below.

To offset the relatively higher cost of maintaining smaller shareholder accounts, if the net asset value of your account is below the fund's minimum initial investment requirement for the particular class of fund shares, the fund may charge your account a fee of $10.00 that is determined and assessed annually.  The small account fee will be charged by redeeming shares in your account.

For certain accounts, if the net asset value of your account is below the fund's minimum initial investment requirement for the particular class of fund shares, the fund reserves the right to redeem all of the remaining shares in your account, close the account and send you the redemption proceeds.  Accounts of shareholders who have accounts in other funds in the BNY Mellon Family of Funds with aggregate net assets of greater than $10,000, accounts participating in automatic investment programs, Retirement Plan accounts and accounts opened through certain financial intermediaries will not be subject to mandatory redemption.

Before either of the actions described above is taken, you will be given 60 days' advance written notice to give you time to increase your account balance to the required minimum amount if you are eligible to invest in the fund and have an address in good order with the fund's transfer agent.

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.

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.

16

The fund's distributions are taxable as ordinary income or capital gains (unless you are investing through an IRA, Retirement Plan or other U.S. tax-advantaged investment plan, or other U.S. tax-advantaged investment plan, in which case taxes may be deferred). Distributions that are federally taxable as ordinary income or capital gains are generally subject to the state's personal income taxes.

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.

If a liquidity fee is imposed in connection with the redemption of your fund shares, the Internal Revenue Service will require you to report any gain or loss recognized from your redemption. If you held your shares as a capital asset, the gain or loss that you recognize will be a capital gain or loss, and will be long-term or short-term, generally depending on how long you have held your shares. Any liquidity fees you incur on shares redeemed will generally decrease the amount of any capital gain (or increase the amount of any capital loss) you recognize with respect to such redemption.

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.

The following services may be available to fund investors. If you purchase shares through a third party financial intermediary or Retirement Plan, the financial intermediary or Retirement Plan recordkeeper, as applicable, may impose different restrictions on these services and privileges, or may not make them available at all. Consult a representative of your financial intermediary or Retirement Plan for further information.

Automatic Services

Buying or selling shares automatically is easy with the services described below. With each service, you select a schedule and amount, subject to certain restrictions. For information, call 1-800-373-9387 (inside the U.S. only) or your financial representative.

Automatic Asset Builder permits you to purchase fund shares (minimum of $100 and maximum of $150,000 per transaction) at regular intervals selected by you. Fund shares are purchased by transferring funds from the bank account designated by you.

Payroll Savings Plan permits you to purchase fund shares (minimum of $100 per transaction) automatically through a payroll deduction.

Government Direct Deposit permits you to purchase fund shares (minimum of $100 and maximum of $50,000 per transaction) automatically from your federal employment, Social Security or other regular federal government check.

Dividend Sweep permits you to automatically reinvest dividends and distributions from the fund in shares of the same class, or another class in which you are eligible to invest, of another fund in the BNY Mellon Family of Funds. Shares held through a Coverdell Education Savings Account sponsored by BNYM Investment Adviser or its affiliates are not eligible for this privilege.

Auto-Exchange Privilege permits you to exchange at regular intervals your fund shares for shares of the same class, or another class in which you are eligible to invest, of another fund in the BNY Mellon Family of Funds.

Automatic Withdrawal Plan permits you to make withdrawals (minimum of $50) on a specific day each month, quarter or semi-annual or annual period, provided your account balance is at least $5,000.

Fund Exchanges

Generally, you can exchange Service shares worth $500 or more (no minimum for Retirement Plans and IRAs sponsored by BNYM Investment Adviser or its affiliates) into shares of the same class, or another class of another fund in the BNY Mellon Family of Funds, provided you meet the eligibility requirements for investing in the new share class, including certain classes of shares of any of the Cash Management Funds designated as a "government money market fund" or a "retail money market fund," which currently include Dreyfus Government Cash Management, Dreyfus Government Securities Cash Management, Dreyfus Treasury Obligations Cash Management and Dreyfus Treasury Securities Cash Management. You can request your exchange by calling 1-800-373-9387 (inside the U.S. only) or your financial representative. Be sure to read the current prospectus for any fund into which you are exchanging before investing. Any new account established through an exchange generally will have the same privileges as your original account (as long as they are available). There is currently no fee for exchanges, although you may be charged a sales load when exchanging into any fund that has one.

17

Your exchange request will be processed on the same business day it is received in proper form, provided that each fund is open at the time of the request (i.e., the request is received by the latest time each fund calculates its NAV for that business day). If the exchange is accepted at a time of day after one or both of the funds is closed (i.e., at a time after the NAV for the fund has been calculated for that business day), the exchange will be processed on the next business day. See the SAI for more information regarding exchanges.

Conversion Feature

Shares of one class of a fund may be converted into shares of another class of the fund, provided the investor meets the eligibility requirements for investing in the new share class. Each fund reserves the right to refuse any conversion request.

Wire Redemption and TeleTransfer Privileges

To redeem shares from your fund account with a phone call (for regular or IRA accounts) or online (for regular accounts only), use the Wire Redemption Privilege or the TeleTransfer Privilege. To purchase additional shares in your fund account with a phone call (for regular or IRA accounts) or online (for regular accounts only), use the TeleTransfer Privilege. You can set up the Wire Redemption Privilege and TeleTransfer Privilege on your account by providing bank account information and following the instructions on your application or, if your account has already been established, a Shareholder Services Form which you can obtain by calling 1-800-373-9387 (inside the U.S. only), contacting your financial representative, visiting bny.com/investments (for individual only) or visiting www.dreyfus.com. Shares held in a Coverdell Education Savings Account may not be redeemed through the Wire Redemption or TeleTransfer Privileges.

Account Statements

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

Checkwriting Privilege

You may write redemption checks against your account in amounts of $500 or more. These checks are free; however, a fee will be charged if you request a stop payment or if the transfer agent cannot honor a redemption check due to insufficient funds or another valid reason. Please do not postdate your checks or use them to close your account. If you request checkwriting privileges, allow approximately two weeks after the fund's receipt of your initial investment for receipt of your checkbook.

By requesting checkwriting privileges, you agree that you will use care in safeguarding unsigned checks against theft or unauthorized use and will inform the fund or the fund's transfer agent if any of your checks are stolen or missing, and that you will not use unmonitored, uncontrolled check stock sourced by you. You further agree that you will be responsible for maintaining security over any device used for your signature, such as a facsimile signature, stamp or other device, and you acknowledge that any signature made on a check using any such device will be effective as your signature, irrespective of whether the person affixing it was authorized to do so. You acknowledge that if you voluntarily provide information about your account, such as the account number and the bank's routing and transit number, to any person in connection with your purchase of goods or services or to a person who is trying to collect a payment from you, any debit related to your account initiated by that person will be deemed to have been authorized by you.

By requesting checkwriting privileges, you further agree that you will promptly review your account statements and other information sent to you by the fund as soon as you receive it. If you believe any statement you receive contains an error or includes an unauthorized, forged, or altered check, you agree to notify the fund or the fund's transfer agent immediately in writing. You must report any errors or irregularities to the fund or the fund's transfer agent within thirty (30) days from the date of the statement you receive and must identify the particular items that you consider to contain an error or to be forged, altered or otherwise unauthorized. If you do not notify the fund or the fund's transfer agent within the required period of time, your account statement will be deemed to be correct and all items properly charged, and you will be precluded from recovering any amounts that you later claim were unauthorized with respect to a payment reflected on that statement. You further agree that neither the fund nor the fund's transfer agent will be liable if you fail to exercise ordinary care in examining your statements. The fund or the fund's transfer agent have the right to assert any legally available defenses to any claim you may assert regarding items paid from your account.
