A LETTER FROM THE PRESIDENT OF BNY MELLON INVESTMENT ADVISER, INC.

Dear Shareholder:

We are pleased to present this semiannual report for BNY Mellon Opportunistic Municipal Securities Fund (formerly, Dreyfus Municipal Bond Opportunity Fund), covering the six-month period from May 1, 2019 through October 31, 2019. For information about how the fund performed during the reporting period, as well as general market perspectives, we provide a Discussion of Fund Performance on the pages that follow.

U.S. equity markets experienced periods of volatility during the reporting period, caused in part by concerns over slowing global growth and trade tensions. Prior to the start of the period, stocks enjoyed steady gains, as investors responded favorably to comments from the U.S. Federal Reserve (the “Fed”). However, the momentum shifted in May 2019, and equity securities began the six months by losing ground. The first month of the period brought increased trade tensions between the U.S. and China and renewed anxiety over moderating global economic growth rates. Markets resumed their upward trajectory in June and July of 2019, when a trade deal appeared more likely, and the pace of U.S. economic growth remained steady. Nevertheless, concerns continued to emerge over slowing global growth, resulting in bouts of market volatility in August 2019. But stocks rebounded in September and continued an upward path through most of October 2019, supported in part by central bank policy and consistent consumer spending.

In fixed-income markets, indices generally rose during the reporting period, as mixed economic data and the Fed’s new data-dependent stance regarding future policy moves suggested the economy could be slowing. Markets had been expecting a loosening of monetary policy, and at the end of July 2019, the Fed cut the federal funds rate by 25 basis points. The Fed cut rates again in September and October, for a total 75-basis-point reduction in the federal funds rate during the six months. Concerns about the pace of global economic growth also fueled demand for fixed-income instruments during much of the reporting period, resulting in positive bond market returns.

We remain optimistic on the near-term economic outlook for the U.S. but will monitor relevant data for any signs of a change. As always, we encourage you to discuss the risks and opportunities in today’s investment environment with your financial advisor.

Thank you for your continued confidence and support.

Sincerely,

Renee LaRoche-Morris
President
BNY Mellon Investment Adviser, Inc.

DISCUSSION OF FUND PERFORMANCE(Unaudited)

For the period from May 1, 2019 through October 31, 2019, as provided by Daniel Rabasco and Jeffrey Burger, portfolio managers

Market and Fund Performance Overview

For the six-month period ended October 31, 2019, BNY Mellon Opportunistic Municipal Securities Fund’s (formerly, Dreyfus Municipal Bond Opportunity Fund) Class A shares produced a total return of 3.85%, Class C shares returned 3.44%, Class I shares returned 3.99%, Class Y shares returned 3.99% and Class Z shares returned 3.88%.¹ In comparison, the Bloomberg Barclays U.S. Municipal Bond Index (the “Index”), the fund’s benchmark index, achieved a total return of 3.54% for the same period.²

Municipal bonds during the reporting period benefited from strong supply-and-demand dynamics. While the fund’s Class C shares lagged the Index, Class A, I, Y and Z shares outperformed the Index, largely due to favorable security selection.

The Fund’s Investment Approach

The fund seeks to maximize current income exempt from federal income tax to the extent consistent with the preservation of capital. To pursue its goal, the fund normally invests at least 80% of its net assets, plus any borrowings for investment purposes, in municipal bonds that provide income exempt from federal income tax. Typically, the fund invests substantially all of its assets in such municipal bonds. The fund invests at least 70% of its assets in municipal bonds rated, at the time of purchase, investment grade (i.e., Baa/BBB or higher) or the unrated equivalent as determined by BNY Mellon Investment Adviser, Inc. (the “Adviser”). For additional yield, the fund may invest up to 30% of its assets in municipal bonds rated below investment grade (“high yield” or “junk” bonds) or the unrated equivalent as determined by the Adviser. The dollar-weighted average maturity of the fund’s portfolio normally exceeds ten years, but the fund may invest without regard to maturity or duration.

The fund’s portfolio managers focus on identifying undervalued sectors and securities and minimize the use of interest-rate forecasting. The portfolio managers select municipal bonds for the fund’s portfolio by using fundamental credit analysis to estimate the relative value and attractiveness of various sectors and securities and to exploit pricing inefficiencies in the municipal bond market, and by actively trading among various sectors, such as pre-refunded, general obligation and revenue, based on their apparent relative values. The fund seeks to invest in several of these sectors.

Strong Demand, Manageable Supply Drove Municipal Bonds

The municipal bond market benefited from strong demand, slowing economic momentum and three interest-rate cuts by the Federal Reserve (the “Fed”). A flight to quality, driven by concerns about global growth and Brexit, was also advantageous.

Robust demand continued as investors in states with high income-tax rates sought to reduce their exposure to federal income taxes, which rose due to a cap on the federal

DISCUSSION OF FUND PERFORMANCE(Unaudited) (continued)

deductibility of state and local taxes imposed by the Tax Cuts and Jobs Act of 2017. Banks and property and casualty insurance companies also returned to the market to some extent. Mixed economic data was also advantageous for the market, as it made the relative safety of municipal bonds more appealing, and led the Fed to cut the federal funds rate by a quarter point three times during the reporting period.

The performance of the market benefited from a reach for yield as investors favored longer-term issues, causing the municipal bond yield curve to flatten during the period. The quest for yield also caused lower-quality issues to outperform higher-quality issues.

Supply remained largely in line with last year’s volume, and this may have been affected somewhat by the elimination of advance refunding and by an increase in issuance in the taxable municipal bond market. In the past, advance refunding allowed issuers to replace higher-yielding tax-exempt debt with lower-yielding tax-exempt debt. Without advance refunding, some entities have taken advantage of low yields by issuing taxable debt instead of tax-exempt debt.

Generally, fundamentals in the municipal bond market remained healthy during the reporting period. Steady but slower economic growth supported tax revenues, fiscal balances and “rainy day” funds. Some issuers even made larger contributions to their pension funds, improving their funded status.

Security Selection Drove Fund Results

The fund’s performance versus the Index was assisted during the reporting period by security selection, particularly in the education, health care, and water and sewer segments of the market. An overweight to revenue bonds versus general obligation bonds was also additive. The fund also maintained a longer duration relative to the Index, which contributed positively to returns as well.

On the other hand, the fund’s selections in transportation and special tax segments hindered performance somewhat. The fund did not make use of derivatives during the reporting period.

A Positive Investment Posture

We expect demand for municipal bonds to remain strong due to the ongoing need of retail investors in high-tax states to shelter income from federal taxes. We also anticipate that municipal-bond supply will grow somewhat, given the low rate environment. States appear to be well prepared for any economic downturn that occurs in the near term, though they still face long-term challenges with pension obligations. We believe credit spreads will remain tight as investors continue to reach for yield, but that volatility could rise if the Fed moves in response to rising inflation. We do not anticipate a Fed move in the near term; however, employment continues to be robust, with unemployment at record-low levels, and wage growth has picked up, raising the prospect of an increase in inflation. One risk to this outlook is a deterioration in trade relations, which could derail the economy’s momentum.

4

We expect to keep the fund’s duration long relative to the Index as the municipal bond yield curve is steeper than the Treasury yield curve, offering more attractive yields. We will continue to focus on revenue bonds, particularly in the health care, airport and essential services segments.

¹Total return includes reinvestment of dividends and any capital gains paid and does not take into consideration the maximum initial sales charge in the case of Class A shares or the applicable contingent deferred sales charge imposed on redemptions in the case of Class C shares. Had these charges been reflected, returns would have been lower. Class I, Class Y, and Class Z are not subject to any initial or deferred sales charge. Past performance is no guarantee of future results. Share price, yield, and investment return fluctuate such that upon redemption, fund shares may be worth more or less than their original cost. Income may be subject to state and local taxes, and some income may be subject to the federal alternative minimum tax (AMT) for certain investors. Capital gains, if any, are taxable.

²Source: Lipper Inc. — The Bloomberg Barclays U.S. Municipal Bond Index covers the U.S.-dollar-denominated, long-term, tax-exempt bond market. Investors cannot invest directly in any index.

Bonds are subject generally to interest-rate, credit, liquidity and market risks, to varying degrees, all of which are more fully described in the fund’s prospectus. Generally, all other factors being equal, bond prices are inversely related to interest-rate changes, and rate increases can cause price declines.

The amount of public information available about municipal bonds 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 bonds. Other factors include the general conditions of the municipal bond 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 in which the fund invests may have an impact on the fund’s share price.

Using the SEC’s method to compare expenses

The Securities and Exchange Commission (“SEC”) has established guidelines to help investors assess fund expenses. Per these guidelines, the table below shows your fund’s expenses based on a $1,000 investment, assuming a hypothetical 5% annualized return. You can use this information to compare the ongoing expenses (but not transaction expenses or total cost) of investing in the fund with those of other funds. All mutual fund shareholder reports will provide this information to help you make this comparison. Please note that you cannot use this information to estimate your actual ending account balance and expenses paid during the period.

Expenses and Value of a $1,000 Investment
Assuming a hypothetical 5% annualized return for the six months ended October 31, 2019
	Class A	Class C	Class I	Class Y	Class Z
Expense paid per $1,000†	$3.71	$7.66	$2.39	$2.39	$3.41
Ending value (after expenses)	$1,021.47	$1,017.55	$1,022.77	$1,022.77	$1,021.77
†  Expenses are equal to the fund’s annualized expense ratio of .73% for Class A, 1.51% for Class C, .47% for Class I, .47% for Class Y and .67% for Class Z, multiplied by the average account value over the period, multiplied by 184/366 (to reflect the one-half year period).

NOTES TO FINANCIAL STATEMENTS (Unaudited)

NOTE 1—Significant Accounting Policies:

BNY Mellon Opportunistic Municipal Securities Fund (the “fund”) is registered under the Investment Company Act of 1940, as amended (the “Act”), is a diversified open-ended management investment company. The fund’s investment objective is to seek to maximize current income exempt from federal income tax to the extent consistent with the preservation of capital. BNY Mellon Investment Adviser, Inc. (the “Adviser”), a wholly-owned subsidiary of The Bank of New York Mellon Corporation (“BNY Mellon”), serves as the fund’s investment adviser.

Effective June 3, 2019, the fund changed its name from Dreyfus Municipal Bond Opportunity Fund to BNY Mellon Opportunistic Municipal Securities Fund. In addition, The Dreyfus Corporation, the fund’s investment adviser, changed its name to “BNY Mellon Investment Adviser, Inc.”, MBSC Securities Corporation, the fund’s distributor, changed its name to “BNY Mellon Securities Corporation” and Dreyfus Transfer, Inc., the fund’s transfer agent, changed its name to “BNY Mellon Transfer, Inc.”

BNY Mellon Securities Corporation (the “Distributor”), a wholly-owned subsidiary of the Adviser, is the distributor of the fund’s shares. The fund is authorized to issue an unlimited number of $.001 par value shares of Beneficial Interest in each of the following classes of shares: Class A, Class C, Class I, Class T, Class Y and Class Z. Class A and Class T shares generally are subject to a sales charge imposed at the time of purchase. Class C shares are subject to a contingent deferred sales charge (“CDSC”) imposed on Class C shares redeemed within one year of purchase. Class C shares automatically convert to Class A shares ten years after the date of purchase, without the imposition of a sales charge. Class I and Class Y shares are sold at net asset value per share generally to institutional investors. Class Z shares are sold at net asset value per share to certain shareholders of the fund. Class Z shares generally are not available for new accounts. As of the date of this report, the fund did not offer Class T shares for purchase. Other differences between the classes include the services offered to and the expenses borne by each class, the allocation of certain transfer agency costs, and certain voting rights. Income, expenses (other than expenses attributable to a specific class), and realized and unrealized gains or losses on investments are allocated to each class of shares based on its relative net assets.

As of October 31, 2019, MBC Investments Corp., an indirect subsidiary of BNY Mellon, held all of outstanding shares of Class Y shares of the fund.

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

The Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) is the exclusive reference of authoritative U.S. generally accepted accounting principles (“GAAP”) recognized by the FASB to be applied by nongovernmental entities. Rules and interpretive releases of the Securities and Exchange Commission (“SEC”) under authority of federal laws are also sources of authoritative GAAP for SEC registrants. The fund is an investment company and applies the accounting and reporting guidance of the FASB ASC Topic 946 Financial Services-Investment Companies. The fund’s financial statements are prepared in accordance with GAAP, which may require the use of management estimates and assumptions. Actual results could differ from those estimates.

The fundenters into contracts that contain a variety of indemnifications. The fund’s maximum exposure under these arrangements is unknown. The fund does not anticipate recognizing any loss related to these arrangements.

(a) Portfolio valuation: The fair value of a financial instrument is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (i.e., the exit price). GAAP establishes a fair value hierarchy that prioritizes the inputs of valuation techniques used to measure fair value. This hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements).

Additionally, GAAP provides guidance on determining whether the volume and activity in a market has decreased significantly and whether such a decrease in activity results in transactions that are not orderly. GAAP requires enhanced disclosures around valuation inputs and techniques used during annual and interim periods.

Various inputs are used in determining the value of the fund’s investments relating to fair value measurements. These inputs are summarized in the three broad levels listed below:

Level 1—unadjusted quoted prices in active markets for identical investments.

Level 2—other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.).

Level 3—significant unobservable inputs (including the fund’s own assumptions in determining the fair value of investments).

30

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

Changes in valuation techniques may result in transfers in or out of an assigned level within the disclosure hierarchy. Valuation techniques used to value the fund’s investments are as follows:

Investments in securities are valued each business day by an independent pricing service (the “Service”) approved by the fund’s Board of Trustees (the “Board”). Investments for which quoted bid prices are readily available and are representative of the bid side of the market in the judgment of the Service are valued at the mean between the quoted bid prices (as obtained by the Service from dealers in such securities) and asked prices (as calculated by the Service based upon its evaluation of the market for such securities). Debt investments (which constitute a majority of the portfolio securities) are carried at fair value as determined by the Service, based on methods which include consideration of the following: yields or prices of municipal securities of comparable quality, coupon, maturity and type; indications as to values from dealers; and general market conditions. All of the preceding securities are generally categorized within Level 2 of the fair value hierarchy.

The Service is engaged under the general oversight of the Board.

When market quotations or official closing prices are not readily available, or are determined not to accurately reflect fair value, such as when the value of a security has been significantly affected by events after the close of the exchange or market on which the security is principally traded, but before the fund calculates its net asset value, the fund may value these investments at fair value as determined in accordance with the procedures approved by the Board. Certain factors may be considered when fair valuing investments such as: fundamental analytical data, the nature and duration of restrictions on disposition, an evaluation of the forces that influence the market in which the securities are purchased and sold, and public trading in similar securities of the issuer or comparable issuers. These securities are either categorized within Level 2 or 3 of the fair value hierarchy depending on the relevant inputs used.

For restricted securities where observable inputs are limited, assumptions about market activity and risk are used and such securities are generally categorized within Level 3 of the fair value hierarchy.

The following is a summary of the inputs used as of October 31, 2019in valuing the fund’s investments:

31

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

Municipal Securities	−	363,255,658	−	363,255,658

^† See Statement of Investments for additional detailed categorizations, if any.

(b) Securities transactions and investment income: Securities transactions are recorded on a trade date basis. Realized gains and losses from securities transactions are recorded on the identified cost basis. Interest income, adjusted for accretion of discount and amortization of premium on investments, is earned from settlement date and recognized on the accrual basis. Securities purchased or sold on a when issued or delayed delivery basis may be settled a month or more after the trade date.

(c) Dividends and distributions to shareholders: It is the policy of the fund to declare dividends daily from investment income-net. Such dividends are paid monthly. Dividends from net realized capital gains, if any, are normally declared and paid annually, but the fund may make distributions on a more frequent basis to comply with the distribution requirements of the Internal Revenue Code of 1986, as amended (the “Code”). To the extent that net realized capital gains can be offset by capital loss carryovers, it is the policy of the fund not to distribute such gains. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP.

(d) Federal income taxes: It is the policy of the fund to continue to qualify as a regulated investment company, which can distribute tax-exempt dividends, by complying with the applicable provisions of the Code, and to make distributions of income and net realized capital gain sufficient to relieve it from substantially all federal income and excise taxes.

As of and during the period ended October 31, 2019, the fund did not have any liabilities for any uncertain tax positions. The fund recognizes interest and penalties, if any, related to uncertain tax positions as income tax expense in the Statement of Operations. During the period ended October 31, 2019, the fund did not incur any interest or penalties.

Each tax year in the three-year period ended April 30, 2019 remains subject to examination by the Internal Revenue Service and state taxing authorities.

32

The tax character of distributions paid to shareholders during the fiscal year ended April 30, 2019 was as follows: tax exempt income $10,202,806 and ordinary income $184,283. The tax character of current year distributions will be determined at the end of the current fiscal year.

(e) New Accounting Pronouncements: Effective June 1, 2019, the fund adopted Accounting Standards Update 2017-08, Receivables—Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization On Purchased Callable Debt Securities (“ASU 2017-08”). The update shortens the amortization period for the premium on certain purchased callable debt securities to the earliest call date.

Also effective June 1, 2019, the fund adopted Accounting Standards Update 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”). The update provides guidance that modifies certain disclosure requirements for fair value measurements. The adoption of ASU 2017-08 and ASU 2018-13 had no impact on the operations of the fund for the period ended October 31, 2019.

NOTE 2—Bank Lines of Credit:

The fund participates with other long-term open-end funds managed by the Adviser in a $1.030 billion unsecured credit facility led by Citibank, N.A. (the “Citibank Credit Facility”) and a $300 million unsecured credit facility provided by The Bank of New York Mellon (the “BNYM Credit Facility”), a subsidiary of BNY Mellon and an affiliate of the Manager, each to be utilized primarily for temporary or emergency purposes, including the financing of redemptions (each, a “Facility”). The Citibank Credit Facility is available in two tranches: (i) Tranche A is in an amount equal to $830 million and is available to all long-term open-ended funds, including the fund, and (ii) Tranche B is in amount equal to $200 million and is available only to BNY Mellon Floating Rate Income Fund, a series of BNY Mellon Investment Funds IV, Inc. In connection therewith, the fund has agreed to pay its pro rata portion of commitment fees for Tranche A of the Citibank Credit Facility and the BNYM Credit Facility. Interest is charged to the fund based on rates determined pursuant to the terms of the respective Facility at the time of borrowing. During the period ended October 31, 2019, the fund did not borrow under the Facilities.

NOTE 3—Management Fee and Other Transactions with Affiliates:

(a) Pursuant to a management agreement with the Adviser, the management fee is computed at the annual rate of .35% of the value of the fund’s average daily net assets and is payable monthly.

33

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

During the period ended October 31, 2019, the Distributor retained $2,194 from commissions earned on sales of the fund’s Class A shares and $30 from CDSC fees on redemptions of the fund’s Class C shares.

(b) Under the Distribution Plan adopted pursuant to Rule 12b-1 under the Act, Class C shares pay the Distributor for distributing its shares at an annual rate of .75% of the value of its average daily net assets. During the period ended October 31, 2019, Class C shares were charged $21,525 pursuant to the Distribution Plan.

(c) Under the Shareholder Services Plan, Class A and Class C shares pay the Distributor at an annual rate of .25% of the value of their average daily net assets and Class Z shares reimburse the Distributor at an annual rate of .20% of the value of its average daily net assets for the provision of certain services. The services provided may include personal services relating to shareholder accounts, such as answering shareholder inquiries regarding the fund and providing reports and other information, and services related to the maintenance of shareholder accounts. The Distributor may make payments to Service Agents (securities dealers, financial institutions or other industry professionals) with respect to these services. The Distributor determines the amounts to be paid to Service Agents. During the period ended October 31, 2019, Class A, Class C and Class Z shares were charged $187,461, $7,175 and $177,936, respectively, pursuant to the Shareholder Services Plan.

The fund has arrangements with the transfer agent and the custodian whereby the fund may receive earnings credits when positive cash balances are maintained, which are used to offset transfer agency and custody fees. For financial reporting purposes, the fund includes net earnings credits, if any, as an expense offset in the Statement of Operations.

The fund compensates BNY Mellon Transfer, Inc., a wholly-owned subsidiary of the Adviser, under a transfer agency agreement for providing transfer agency and cash management services for the fund. The majority of transfer agency fees are comprised of amounts paid on a per account basis, while cash management fees are related to fund subscriptions and redemptions. During the period ended October 31, 2019, the fund was charged $41,067 for transfer agency services. These fees are included in Shareholder servicing costs in the Statement of Operations.

The fund compensates The Bank of New York Mellon under a custody agreement for providing custodial services for the fund. These fees are determined based on net assets, geographic region and transaction activity. During the period ended October 31, 2019, the fund was charged $1,200 pursuant to the custody agreement.

34

The fund compensates The Bank of New York Mellon under a shareholder redemption draft processing agreement for providing certain services related to the fund’s check writing privilege.

INFORMATION ABOUT THE RENEWAL OF THE FUND’S MANAGEMENT AGREEMENT (Unaudited)

At a meeting of the fund’s Board of Trustees held on August 6, 2019, the Board considered the renewalof the fund’s Management Agreement pursuant to which the Adviser provides the fund with investment advisory and administrative services (the “Agreement”). The Board members, none of whom are “interested persons” (as defined in the Investment Company Act of 1940, as amended) of the fund, were assisted in their review by independent legal counsel and met with counsel in executive session separate from representatives of the Adviser. In considering the renewal of the Agreement, the Board considered all factors that it believed to be relevant, including those discussed below. The Board did not identify any one factor as dispositive, and each Board member may have attributed different weights to the factors considered.

Analysis of Nature, Extent, and Quality of Services Provided to the Fund. The Board considered information provided to it at the meeting and in previous presentations from representatives of the Adviser regarding the nature, extent, and quality of the services provided to funds in the BNY Mellon fund complex. The Adviser provided the number of open accounts in the fund, the fund’s asset size and the allocation of fund assets among distribution channels. The Adviser also had previously provided information regarding the diverse intermediary relationships and distribution channels of funds in the BNY Mellon fund complex (such as retail direct or intermediary, in which intermediaries typically are paid by the fund and/or the Adviser) and the Adviser’s corresponding need for broad, deep, and diverse resources to be able to provide ongoing shareholder services to each intermediary or distribution channel, as applicable to the fund.

The Board also considered research support available to, and portfolio management capabilities of, the fund’s portfolio management personnel and that the Adviser also provides oversight of day-to-day fund operations, including fund accounting and administration and assistance in meeting legal and regulatory requirements. The Board also considered the Adviser’s extensive administrative, accounting and compliance infrastructures.

Comparative Analysis of the Fund’s Performance and Management Fee and Expense Ratio. The Board reviewed reports prepared by Broadridge Financial Solutions, Inc. (“Broadridge”), an independent provider of investment company data, which included information comparing (1) the fund’s performance with the performance of a group of comparable funds (the “Performance Group”) and with a broader group of funds (the “Performance Universe”), all for various periods ended June 30, 2019, and (2) the fund’s actual and contractual management fees and total expenses with those of a group of comparable funds (the “Expense Group”) and with a broader group of funds (the “Expense Universe”), the information for which was derived in part from fund financial statements available to Broadridge as of the date of its analysis. The Adviser previously had furnished the Board with a description of the methodology Broadridge used to select the Performance Group and Performance Universe and the Expense Group and Expense Universe.

Representatives of the Adviser stated that the usefulness of performance comparisons may be affected by a number of factors, including different investment limitations and policies that may be applicable to the fund and comparison funds. The Board discussed with representatives of the Adviser and/or its affiliates the results of the comparisons and considered that the fund’s total return performance was above the Performance Group median for all periods and at or above the Performance Universe median for all periods except for the three- and ten-year periods when performance was below the Performance Universe median. The Board also considered that the fund’s yield performance was below the Performance Group median for eight of the ten one-year periods and above the Performance Universe median for seven of the ten one-year periods ended June 30^th. The Board considered the relative proximity of the fund’s total return and yield performance to the Performance Group and/or Performance Universe median in certain periods when performance was below median. The Adviser also provided a comparison of the fund’s calendar year total returns to the returns of the fund’s benchmark index.

The Board also reviewed the range of actual and contractual management fees and total expenses of the Expense Group and Expense Universe funds and discussed the results of the comparisons. The Board considered that the fund’s contractual management fee was below the Expense Group median (lowest in the Expense Group) and the fund’s actual management fee and total expenses were above the Expense Group and Expense Universe medians.

Representatives of the Adviser reviewed with the Board the management or investment advisory fees (1) paid by funds advised or administered by the Adviser that are in the same Lipper category as the fund and (2) paid to the Adviser, or the primary employer of the fund’s primary portfolio manager(s) that is affiliated with the Adviser, for advising any separate accounts and/or other types of client portfolios that are considered to have similar investment strategies and policies as the fund (the “Similar Clients”), and explained the nature of the Similar Clients. They discussed differences in fees paid and the relationship of the fees paid in light of any differences in the services provided and other relevant factors. The Board considered the relevance of the fee information provided for the Similar Clients to evaluate the appropriateness of the fund’s management fee.

Analysis of Profitability and Economies of Scale. Representatives of the Adviser reviewed the expenses allocated and profit received by the Adviser and its affiliates and the resulting profitability percentage for managing the fund and the aggregate profitability percentage to the Adviser and its affiliates for managing the funds in the BNY Mellon fund complex, and the method used to determine the expenses and profit. The Board concluded that the profitability results were not unreasonable, given the services rendered and service levels provided by the Adviser. The Board also had been provided with information prepared by an independent consulting firm regarding the Adviser’s approach to allocating costs to, and determining the profitability of, individual funds and the entire BNY Mellon fund complex. The consulting firm also had analyzed

37

INFORMATION ABOUT THE RENEWAL OF THE FUND’S MANAGEMENT AGREEMENT (Unaudited) (continued)

where any economies of scale might emerge in connection with the management of a fund.

The Board considered, on the advice of its counsel, the profitability analysis (1) as part of its evaluation of whether the fees under the Agreement, considered in relation to the mix of services provided by the Adviser, including the nature, extent and quality of such services, supported the renewal of the Agreement and (2) in light of the relevant circumstances for the fund and the extent to which economies of scale would be realized if the fund grows and whether fee levels reflect these economies of scale for the benefit of fund shareholders. Representatives of the Adviser stated that a discussion of economies of scale is predicated on a fund having achieved a substantial size with increasing assets and that, if a fund’s assets had been stable or decreasing, the possibility that the Adviser may have realized any economies of scale would be less. Representatives of the Adviser also stated that, as a result of shared and allocated costs among funds in the BNY Mellon fund complex, the extent of economies of scale could depend substantially on the level of assets in the complex as a whole, so that increases and decreases in complex-wide assets can affect potential economies of scale in a manner that is disproportionate to, or even in the opposite direction from, changes in the fund’s asset level. The Board also considered potential benefits to the Adviser from acting as investment adviser and took into consideration that there were no soft dollar arrangements in effect for trading the fund’s investments.

At the conclusion of these discussions, the Board agreed that it had been furnished with sufficient information to make an informed business decision with respect to the renewal of the Agreement. Based on the discussions and considerations as described above, the Board concluded and determined as follows.

·The Board concluded that the nature, extent and quality of the services provided by the Adviser are adequate and appropriate.

·The Board generally was satisfied with the fund’s overall performance.

·The Board concluded that the fee paid to the Adviser continued to be appropriate under the circumstances and in light of the factors and the totality of the services provided as discussed above.

·The Board determined that the economies of scale which may accrue to the Adviser and its affiliates in connection with the management of the fund had been adequately considered by the Adviser in connection with the fee rate charged to the fund pursuant to the Agreement and that, to the extent in the future it were determined that material economies of scale had not been shared with the fund, the Board would seek to have those economies of scale shared with the fund.

In evaluating the Agreement, the Board considered these conclusions and determinations and also relied on its previous knowledge, gained through meetings and other interactions with the Adviser and its affiliates, of the Adviser and the services provided to the fund by the Adviser. The Board also relied on information received on a routine and regular basis throughout the year relating to the operations of the fund and

38

the investment management and other services provided under the Agreement, including information on the investment performance of the fund in comparison to similar mutual funds and benchmark performance indices; general market outlook as applicable to the fund; and compliance reports. In addition, the Board’s consideration of the contractual fee arrangements for this fund had the benefit of a number of years of reviews of the Agreement for the fund, or substantially similar agreements for other BNY Mellon funds that the Board oversees, during which lengthy discussions took place between the Board and representatives of the Adviser. Certain aspects of the arrangements may receive greater scrutiny in some years than in others, and the Board’s conclusions may be based, in part, on their consideration of the fund’s arrangements, or substantially similar arrangements for other BNY Mellon funds that the Board oversees, in prior years. The Board determined to renew the Agreement.
