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. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example - BNY Mellon Municipal Opportunities Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
Class M	66	208	362	810
Investor	92	287	498	1,108

Expense Example No Redemption - BNY Mellon Municipal Opportunities Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
Class M	66	208	362	810
Investor	92	287	498	1,108

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 57.75% of the average value of its portfolio.

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 U.S. dollar-denominated fixed-income securities that provide income exempt from federal personal income tax (municipal bonds). Municipal bonds are debt securities or other obligations issued by states, territories and possessions of the United States and the District of Columbia and their political subdivisions, agencies and instrumentalities, or multistate agencies and authorities, and certain other specified securities. While the fund typically invests in a diversified portfolio of municipal bonds, it may invest up to 20% of its net assets in taxable fixed-income securities, including

taxable municipal bonds and non-U.S. dollar-denominated foreign debt securities such as Brady bonds and sovereign debt obligations.

The fund invests at least 50% of its net assets in fixed-income securities that are rated investment grade (i.e., Baa/BBB or higher) or are the unrated equivalent as determined by BNY Mellon Investment Adviser, Inc. (BNYM Investment Adviser). For additional yield, the fund may invest up to 50% of its net assets in fixed-income securities that are rated below investment grade ("high yield" or "junk" bonds) or are the unrated equivalent as determined by BNYM Investment Adviser. The fund may invest in bonds of any maturity or duration and does not expect to target any specific range of maturity or duration. The dollar-weighted average maturity of the fund's portfolio will vary from time to time depending on the portfolio manager's views on the direction of interest rates. A bond's maturity is the length of time until the principal must be fully repaid with interest. Dollar-weighted average maturity is an average of the stated maturities of the securities held by the fund, based on their dollar-weighted proportions in the fund. Duration is an indication of an investment's "interest rate risk," or how sensitive a bond or the fund's portfolio may be to changes in interest rates.

The fund's portfolio manager seeks to deliver value added excess returns ("alpha") by applying an investment approach designed to identify and exploit relative value opportunities within the municipal bond market and other fixed-income markets.

The fund typically sells a security when the fund's portfolio manager believes that there has been a negative change in the credit quality of the issuer or has identified a more attractive opportunity or when the portfolio manager seeks to manage the fund's duration or tax position or to provide liquidity to meet shareholder redemptions.

The fund may use derivatives as a substitute for investing directly in an underlying asset, to increase returns, to manage duration, interest rate or foreign currency risk, or as part of a hedging strategy. The derivative instruments in which the fund may invest include typically futures (including those relating to securities, indices, foreign currencies and interest rates). The fund also may purchase or sell securities on a forward commitment, when-issued or delayed-delivery basis, which means delivery and payment take place at a future date at a predetermined price and/or yield.

Principal Risks

An investment in the fund is not a bank deposit. It is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency. It is not a complete investment program. The fund's share price fluctuates, sometimes dramatically, which means you could lose money.

● Municipal securities risk. The amount of public information available about municipal securities is generally less than that for corporate equities or bonds. Special factors, such as legislative changes, and state and local economic and business developments, may adversely affect the yield and/or value of the fund's investments in municipal securities. Other factors include the general conditions of the municipal securities market, the size of the particular offering, the maturity of the obligation and the rating of the issue. Changes in economic, business or political conditions relating to a particular municipal project, municipality, or state, territory or possession of the United States in which the fund invests may have an impact on the fund's share price. As an example, elevated costs or shortfalls in revenue associated with the spread of the COVID-19 outbreak could affect the ability of municipal issuers to make payments on debt obligations when due. Any such credit impairment could adversely impact the value of their bonds, which could negatively impact the performance of the fund.

● 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. 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. Very low or negative interest rates may magnify interest rate risk. 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.

● 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.

● 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.

● High yield securities risk. High yield ("junk") securities involve greater credit risk, including the risk of default, than investment grade securities, and are considered predominantly speculative with respect to the issuer's ability to make principal and interest payments. These securities are especially sensitive to adverse changes in general economic conditions, to changes in the financial condition of their issuers and to price fluctuation in response to changes in interest rates. During periods of economic downturn or rising interest rates, issuers of below investment grade securities may experience financial stress that could adversely affect their ability to make payments of principal and interest and increase the possibility of default.

● 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. The secondary market for certain municipal bonds tends to be less well developed or liquid than many other securities markets, which may adversely affect the fund's ability to sell such municipal bonds at attractive prices. 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.

● Derivatives risk. A small investment in derivatives 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. 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. Certain derivatives have the potential for unlimited loss, regardless of the size of the initial investment, and involve greater risks than the underlying assets because, in addition to general market risks, they are subject to liquidity risk, credit and counterparty risk (failure of the counterparty to the derivatives transaction to honor its obligation) and pricing risk (risk that the derivative cannot or will not be accurately valued).

● Forward commitments risk. Debt securities purchased on a forward commitment, when-issued or delayed-delivery basis are subject to changes in value based upon the perception of the creditworthiness of the issuer and changes, real or anticipated, in the level of interest rates (i.e., appreciating when interest rates decline and depreciating when interest rates rise). When purchasing a security on a forward commitment basis, the fund would assume the risks of ownership of the security, including the risk of price fluctuations, and takes such fluctuations into account when determining its net asset value. The sale of securities on a forward commitment or delayed-delivery basis involves the risk that the prices available in the market on the delivery date may be greater than those obtained in the sale transaction.

● 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 exposure to currency fluctuations, less liquidity, less developed or less efficient trading markets, lack of comprehensive company information, political and economic instability and differing auditing and legal standards.

● 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. 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. 

● Management risk. The investment process used by the fund's portfolio manager could fail to achieve the fund's investment goal and cause your fund investment to lose value.

Performance

The following bar chart and table provide some indication of the risks of investing in the fund. The bar chart shows the performance of the fund's Class M shares from year to year. The table compares the average annual total returns of the fund's Class M shares and Investor shares to those of the Bloomberg U.S. Municipal Bond Index.

After-tax performance is shown only for Class M shares. After-tax performance of the fund's Investor shares will vary. After-tax returns are calculated using the historical highest individual federal marginal tax rates, and do not reflect the impact of state and local taxes. Actual after-tax returns depend on the investor's tax situation and may differ from those shown, and the after-tax returns shown are not relevant to investors who hold their shares through U.S. tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

The fund's past performance (before and after taxes) is not necessarily an indication of how the fund will perform in the future. Performance for each share class will vary due to differences in expenses.
