Summary Investment Objective The fund seeks to match the total return of the Bloomberg U.S. Aggregate Bond Index. Fees and Expenses 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. Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment) 0.0015 0.0015 0 0.0025 0.0001 0.0001 0.0016 0.0041 -0.0001 -0.0001 0.0015 0.0040 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 Example is based on net operating expenses, which reflects the contractual undertaking by BNY Mellon Investment Adviser, Inc. Although your actual costs may be higher or lower, based on these assumptions your costs would be: 15 48 85 192 41 128 224 505 Portfolio Turnover The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the fund's performance. During the most recent fiscal year, the fund's portfolio turnover rate was 181.20% of the average value of its portfolio. 1.8120 Principal Investment Strategy To pursue its goal, the fund normally invests at least 80% of its net assets, plus any borrowings for investment purposes, in bonds that are included in the Bloomberg U.S. Aggregate Bond Index (or other instruments with similar economic characteristics). In seeking to match index performance, the fund's portfolio managers use a passive management approach and generally purchase a representative sample of the bonds comprising the Bloomberg U.S. Aggregate Bond Index. Because the fund has expenses, performance will tend to be slightly lower than that of the index. The fund attempts to have a correlation between its performance and that of the Bloomberg U.S. Aggregate Bond Index of at least .95 before expenses. A correlation of 1.00 would mean that the fund and the index were perfectly correlated.The fund's investments are selected by a "sampling" process, which is a statistical process used to select bonds so that the fund has investment characteristics that closely approximate those of the index. By using this sampling process, the fund typically will not invest in all of the securities in the Bloomberg U.S. Aggregate Bond Index.The Bloomberg U.S. Aggregate Bond Index is a broad-based, unmanaged index that measures the investment grade (Baa3/BBB-/BBB- or higher), U.S. dollar-denominated, fixed-rate taxable bond market. The index includes Treasuries, government-related and corporate securities, fixed-rate agency mortgage-backed securities, asset-backed securities and commercial mortgage-backed securities (agency and non-agency). Although most of the securities in the index are issued by the U.S. Treasury and other U.S. government and agency issuers, the index may include U.S. dollar-denominated bonds issued by foreign issuers in which the fund may invest to the extent the index contains such securities. To maintain liquidity, the fund may invest up to 20% of its net assets in various short-term, fixed-income securities and money market instruments. The fund also may use index futures as a substitute for the sale or purchase of securities and purchase or sell securities on a forward commitment (including "TBA" (to be announced)) basis. A derivatives contract, such as futures contracts, will obligate or entitle the fund to deliver or receive an asset or cash payment based on the change in value of the underlying asset. The fund may engage in short-term trading in the execution of its investment strategy, which will increase portfolio turnover.The fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the index is concentrated.

It is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency. The fund's share price fluctuates, sometimes dramatically, which means you could lose money. · Fixed-income market risk: The market value of a fixed-income security may decline due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic conditions, changes in the outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity can decline unpredictably in response to overall economic conditions or credit tightening. Increases in volatility and decreases in liquidity may be caused by a rise in interest rates (or the expectation of a rise in interest rates). An unexpected increase in fund redemption requests, including requests from shareholders who may own a significant percentage of the fund's shares, which may be triggered by market turmoil or an increase in interest rates, could cause the fund to sell its holdings at a loss or at undesirable prices and adversely affect the fund's share price and increase the fund's liquidity risk, fund expenses and/or taxable distributions. Federal Reserve policy in response to market conditions, including with respect to interest rates, may adversely affect the value, volatility and liquidity of dividend and interest paying securities. Policy and legislative changes worldwide are affecting many aspects of financial regulation. The impact of these changes on the markets and the practical implications for market participants may not be fully known for some time. · Interest rate risk: Prices of bonds and other fixed rate fixed-income securities tend to move inversely with changes in interest rates. Typically, a rise in rates will adversely affect fixed-income securities and, accordingly, will cause the value of the fund's investments in these securities to decline. 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. During periods of very low interest rates, which occur from time to time due to market forces or actions of governments and/or their central banks, including the Board of Governors of the Federal Reserve System in the U.S., the fund may be subject to a greater risk of principal decline from rising interest rates. When interest rates fall, the fund's investments in new securities may be at lower yields and may reduce the fund's income. Changing interest rates may have unpredictable effects on markets, may result in heightened market volatility and may detract from fund performance. The magnitude of these fluctuations in the market price of fixed-income securities is generally greater for securities with longer effective maturities and durations because such instruments do not mature, reset interest rates or become callable for longer periods of time. The change in the value of a fixed-income security or portfolio can be approximated by multiplying its duration by a change in interest rates. · 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. The lower a security's credit rating, the greater the chance that the issuer of the security will default or fail to meet its payment obligations. · 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. · Indexing strategy risk: The fund uses an indexing strategy. It does not attempt to manage market volatility, use defensive strategies or reduce the effects of any long-term periods of poor index performance. The correlation between fund and index performance may be affected by the fund's expenses and use of sampling techniques, changes in securities markets, changes in the composition of the index and the timing of purchases and redemptions of fund shares. · Index sampling risk: The fund's use of sampling techniques will result in it holding a smaller number of securities than are in the index, and the fund may not track the index as closely as it would if it were fully replicating the index. · Concentration risk: The fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the index is concentrated. To the extent the fund concentrates in a particular industry or group of industries or sector, it may be more susceptible to economic conditions and risks affecting those industries or sectors. · Mortgage-related securities risk: Mortgage-related 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. The fund is subject to the credit risk associated with these securities, including the market's perception of the creditworthiness of the issuing federal agency, as well as the credit quality of the underlying assets. Although certain mortgage-related securities are guaranteed as to the timely payment of interest and principal by a third party (such as a U.S. government agency or instrumentality with respect to government-related mortgage securities) the market prices for such securities are not guaranteed and will fluctuate. As with other interest-bearing securities, the prices of certain mortgage-related securities are inversely affected by changes in interest rates. However, although the value of a mortgage-related security may decline when interest rates rise, the converse is not necessarily true, since in periods of declining interest rates the mortgages underlying the security are more likely to be prepaid causing the fund to purchase new securities at current market rates, which usually will be lower. The loss of higher yielding underlying mortgages and the reinvestment of proceeds at lower interest rates, known as prepayment risk, can reduce the fund's potential price gain in response to falling interest rates, reduce the fund's yield and/or cause the fund's share price to fall. When interest rates rise, the effective duration of the fund's mortgage-related and other asset-backed securities may lengthen due to a drop in prepayments of the underlying mortgages or other assets. This is known as extension risk and would increase the fund's sensitivity to rising interest rates and its potential for price declines. · 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. · Prepayment risk: Some securities give the issuer the option to prepay or call the securities before their maturity date, which may reduce the market value of the security and the anticipated yield-to-maturity. Issuers often exercise this right when interest rates fall. If an issuer "calls" its securities during a time of declining interest rates, the fund might have to reinvest the proceeds in an investment offering a lower yield, and therefore might not benefit from any increase in value as a result of declining interest rates. During periods of market illiquidity or rising interest rates, prices of "callable" issues are subject to increased price fluctuation. · Foreign investment risk: To the extent the fund invests in foreign securities, the fund's performance will be influenced by political, social and economic factors affecting investments in foreign issuers. Special risks associated with investments in foreign issuers include less liquidity, less developed or less efficient trading markets, lack of comprehensive company information, political and economic instability and differing auditing and legal standards. · 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 and the fund's share price may fall dramatically. Investments that are illiquid or that trade in lower volumes may be more difficult to value. Investments in foreign securities tend to have greater exposure to liquidity risk than domestic securities. · Valuation risk: The price that the fund could receive upon the sale (or other disposition) of an investment may differ from the fund's valuation of the investment, particularly for investments that trade in lower volumes, investments that are valued using a fair valuation methodology or a price provided by an independent pricing service, or during market turmoil or volatility. As a result, the price received upon the sale of an investment may be less than the value ascribed by the fund, and the fund could realize a greater than expected loss or lesser than expected gain upon the sale of the investment. The fund's ability to value its investments also may be impacted by technological issues and/or errors by pricing services or other third-party service providers. · Issuer risk: A security's market value may decline for a number of reasons which directly relate to the issuer, or to factors that affect the issuer's industry. · Market risk: The value of the securities in which the fund invests may be affected by political, regulatory, economic and social developments, and developments that impact specific economic sectors, industries or segments of the market. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or fixed-income markets may negatively affect many issuers, which could adversely affect the fund. Global economies and financial markets are becoming increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers in a different country, region or financial market. These risks may be magnified if certain events or developments adversely interrupt the global supply chain; in these and other circumstances, such risks might affect companies world-wide. Local, regional or global events such as war, military conflicts, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, recessions, elevated levels of government debt, changes in trade regulation or economic sanctions, internal unrest and discord, or other events could have a significant impact on the fund and its investments. · Derivatives risk: A small investment in derivatives, such as futures contracts, could have a potentially large impact on the fund's performance. The use of derivatives involves risks different from, or possibly greater than, the risks associated with investing directly in the underlying assets, and the fund's use of derivatives may result in losses to the fund and increased portfolio volatility. Derivatives in which the fund may invest can be highly volatile, illiquid and difficult to value, and there is the risk that changes in the value of a derivative held by the fund will not correlate with the underlying assets or the fund's other investments in the manner intended. · Portfolio turnover risk: The fund may engage in short-term trading, which could produce higher transaction costs and taxable distributions, and lower the fund's after-tax performance.

Fees and Expenses 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. Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment) 0.0020 0.0002 0.0022 -0.0001 0.0021 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 Example is based on net operating expenses, which reflects the contractual undertaking by BNY Mellon Investment Adviser, Inc. Although your actual costs may be higher or lower, based on these assumptions your costs would be: 22 68 118 268 Portfolio Turnover The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the fund's performance. During the most recent fiscal year, the fund's portfolio turnover rate was 2.69% of the average value of its portfolio. 0.0269 Principal Investment Strategy To pursue its goal, the fund normally invests at least 95% of its total assets in common stocks included in the S&P 500® Index. To replicate index performance, the fund's portfolio managers use a passive management approach and generally purchase all of the securities comprising the S&P 500® Index (though, at times, the fund may invest in a representative sample of the S&P 500® Index). Because the fund has expenses, performance will tend to be slightly lower than that of the S&P 500® Index. The fund attempts to have a correlation between its performance and that of the S&P 500® Index of at least .95, before expenses. A correlation of 1.00 would mean that the fund and the index were perfectly correlated. The S&P 500® Index is an unmanaged index that measures the performance of the large-cap segment of the U.S. market. Considered to be a proxy of the U.S. equity market, the index is composed of 500 constituent companies. Standard & Poor's weights each company's stock in the index by its market capitalization (i.e., the share price times the number of shares outstanding), adjusted by the number of available float shares (i.e., those shares available to public investors. As of February 2026, companies included in the S&P 500® Index generally must have market capitalizations of $22.7 billion or more. The fund may operate as a non-diversified fund, as defined under the Investment Company Act of 1940, as amended, to the approximate extent the S&P 500® Index is non-diversified, without shareholder approval. The fund may therefore operate as non-diversified solely as a result of a change in relative market capitalization or index weighting of one or more constituents of the index.The fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the index is concentrated. In addition, to the extent the fund purchases securities comprising the S&P 500® Index, the fund may, from time to time, invest a significant portion of its assets in securities of companies in certain sectors, such as the information technology sector.

The fund's share price fluctuates, sometimes dramatically, which means you could lose money. · Risks of stock investing: Stocks generally fluctuate more in value than bonds and may decline significantly over short time periods. There is the chance that stock prices overall will decline because stock markets tend to move in cycles, with periods of rising prices and falling prices. The market value of a stock may decline due to general market conditions or because of factors that affect the particular company or the company's industry. · Indexing strategy risk: The fund uses an indexing strategy. It does not attempt to manage market volatility, use defensive strategies or reduce the effects of any long-term periods of poor index performance. The correlation between fund and index performance may be affected by the fund's expenses and/or use of sampling techniques, changes in securities markets, changes in the composition of the index and the timing of purchases and redemptions of fund shares. · Concentration risk: The fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the index is concentrated.

A non-diversified fund may invest a greater portion of its assets in securities of a smaller number of individual issuers than a diversified fund. As a result, the fund's performance may be more vulnerable to changes in the market value of a single issuer or group of issuers and more susceptible to risks associated with a single economic, political or regulatory occurrence than a diversified fund.
