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

Dear Shareholder:

We are pleased to present this semiannual report for BNY Mellon Midcap Index Fund, Inc., covering the six-month period from November 1, 2019 through April 30, 2020. 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.

Stock markets performed well over the last several months of 2019. Accommodative policies from the U.S. Federal Reserve (the “Fed”), paired with healthy U.S. consumer spending, helped support valuations. Despite periodic investor concern regarding trade relations with China and global growth rates, the rally continued through the end of the calendar year, supported in part by a December announcement that the first phase of a trade deal with China was in process. U.S. equity markets reached new highs during the final months of 2019. However, the euphoria was short-lived, as concerns over the spread of COVID-19 and widespread quarantine roiled markets during the first several months of 2020; stocks posted historic losses in March 2020 but regained some ground in April.

In fixed-income markets, interest rates were heavily influenced by changes in Fed policy and investor concern over COVID-19. As stocks rallied in November and December 2019, Treasury bond prices declined, and rates across much of the yield curve rose until early in 2020, when the threat posed by COVID-19 began to emerge. A flight to quality ensued, and rates fell significantly. March 2020 brought high volatility and risk-asset spread widened. The Fed cut rates twice in March, and the government launched a large stimulus package. In April 2020, bond prices began to recover some of their prior losses.

The near-term outlook for the U.S. will be challenging, as the country continues to face COVID-19. However, we believe that once the economic effects have been mitigated, the economy will rebound. As always, we will monitor relevant data for signs of change. 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 November 1, 2019 through April 30, 2020, as provided by Thomas J. Durante, CFA, Karen Q. Wong, CFA and Richard A. Brown, CFA, Portfolio Managers

Market and Fund Performance Overview

For the six-month period ended April 30, 2020, BNY Mellon Midcap Index Fund, Inc. Investor shares returned -15.24%, and its Class I shares produced a total return of -15.16%.¹ In comparison, the S&P MidCap 400^® Index (the “Index”), the fund’s benchmark, produced a total return of -15.02% for the same period.^2,3

Mid-cap stocks fell during the reporting period, due largely to volatility brought on by the spread of COVID-19. The difference in returns between the fund and the Index during the reporting period was primarily the result of transaction costs and operating expenses that are not reflected in the Index’s results.

The Fund’s Investment Approach

The fund seeks to match the performance of the Index. To pursue its goal, the fund generally is fully invested in stocks included in the Index and in futures whose performance is tied to the Index. The fund generally invests in all 400 stocks in the Index, in proportion to their weighting in the Index.

The Index is an unmanaged index of 400 common stocks of medium-sized companies. S&P 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). Companies included in the Index generally have market capitalizations ranging between approximately $2.4 billion and $8.2 billion, to the extent consistent with market conditions.

Geopolitics, Pandemic and Central Banks Influence Markets

Equity markets were affected by an array of geopolitical developments in late 2019, ranging from civil protests in Hong Kong to an impeachment inquiry against the U.S. president and the Brexit saga in the U.K. The continuing trade tensions between the U.S. and China remained an influencer of investor sentiment and equity market valuations early in the period. Alternating signs of progress and deterioration in the trade dispute occurred, although the year concluded with President Trump indicating that he would sign the first phase of a deal. Investor optimism helped fuel a rally that pushed U.S. equity indices to new record highs in December 2019.

Volatility reentered equity markets in January 2020, due to concerns over the spread of COVID-19 and the resulting economic implications. Although some indices hit new record highs in early February 2020, investor sentiment shifted later in the month, due to increasing

DISCUSSION OF FUND PERFORMANCE (Unaudited) (continued)

COVID-19 cases in the U.S. A sell-off began that accelerated through late March 2020, eliminating gains for many areas of the capital markets, and sending some equity indices into bear market territory. Asset valuations came under additional pressure from the Russia and Saudi Arabia oil conflict, which caused the price of oil to fall precipitously. The U.S. Federal Reserve (the “Fed”) cut the federal funds target rate twice in March 2020, in an effort to support the economy. Large numbers of people were laid off after several states ordered non-essential businesses closed. A landmark $2 trillion-dollar stimulus deal was signed on March 27^th, in an effort to provide much needed cash to households and loans to small businesses. Markets stabilized, and many indices gained ground in April 2020.

In this environment, mid-cap stocks produced lower returns than their large-cap counterparts but outperformed small-cap equities.

Financials Stocks Weigh on the Market

In a falling rate environment, financials stocks struggled. Mid-sized banks were particularly hard hit, and several were downgraded during the period. Lower rates generally reduce the profitability of lending products. Insurance companies also came under pressure, as investors speculated over the possible extent of costs associated with COVID-19 claims. As people sheltered in place, real estate securities were also hit. Business, retail and college housing REITs were particularly affected as people stayed home. Within the consumer discretionary sector, hotels, restaurants and leisure, along with specialty retail, were the worst performing industries. People are generally not traveling for business or pleasure and are not currently using hotels. Restaurants are not allowing in-house dining. Consumer spending has shifted online, taking business away from more footfall-dependent, specialty retail businesses, particularly those without strong online presence.

There were spots of resilience within the mid-cap markets. The health care sector posted a positive return and led the Index for the period. Equipment and supplies companies, particularly those that produce diagnostic testing supplies, generally performed well. In addition, injectable medicines companies rose on technology innovation that was rolled out during the period. Remote body systems monitoring companies were able to benefit from an increase in demand, due to the shift to more medical care being provided through online applications. Of course, companies producing antibody tests for COVID-19 also rose during the period. Lastly, beer and pizza companies fared well within the consumer staples sector. The defensive nature of alcohol companies and the deliverability of pizza led to high demand for these products.

Replicating the Performance of the Index

Although we do not actively manage the fund’s investments in response to macroeconomic trends, it is worth noting that while the spread of COVID-19 and resulting economic implications continue to impact markets and the economy, the U.S. government and Fed

remain dedicated to support capital markets and the economy with various fiscal and monetary techniques. As always, we continue to monitor factors that affect the fund’s investments.

¹Total return includes reinvestment of dividends and any capital gains paid. Past performance is no guarantee of future results. Share price and investment return fluctuate such that upon redemption, fund shares may be worth more or less than their original cost.

²Source: Lipper Inc. — The S&P MidCap 400^® Index provides investors with a benchmark for midsized companies. The Index measures the performance of midsized companies, reflecting the distinctive risk and return characteristics of this market segment. Investors cannot invest directly in any index.

³“Standard & Poor’s^®,” “S&P^®,” and “S&P MidCap 400^®” are registered trademarks of Standard & Poor’s Financial Services LLC and have been licensed for use on behalf of the fund. The fund is not sponsored, endorsed, managed, advised, sold or promoted by Standard & Poor’s and its affiliates, and Standard & Poor’s and its affiliates make no representation regarding the advisability of investing in the fund.

Equities are subject generally to market, market sector, market liquidity, issuer and investment style risks, among other factors, to varying degrees, all of which are more fully described in the fund’s prospectus.

Recent market risks include pandemic risks related to COVID-19. The effects of COVID-19 have contributed to increased volatility in global markets and will likely affect certain countries, companies, industries and market sectors more dramatically than others. To the extent the fund may overweight its investments in certain countries, companies, industries or market sectors, such positions will increase the fund’s exposure to risk of loss from adverse developments affecting those countries, companies, industries or sectors.

The prices of mid-cap company stocks tend to be more volatile than the prices of large company stocks, mainly because these companies have less established and more volatile earnings histories. They also tend to be less liquid than larger company stocks.

The fund may, but is not required, to use derivative instruments. 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.

UNDERSTANDING YOUR FUND’S EXPENSES (Unaudited)

As a mutual fund investor, you pay ongoing expenses, such as management fees and other expenses. Using the information below, you can estimate how these expenses affect your investment and compare them with the expenses of other funds. You also may pay one-time transaction expenses, including sales charges (loads) and redemption fees, which are not shown in this section and would have resulted in higher total expenses. For more information, see your fund’s prospectus or talk to your financial adviser.

Review your fund’s expenses

The table below shows the expenses you would have paid on a $1,000 investment in BNY Mellon Midcap Index Fund, Inc. from November 1, 2019 to April 30, 2020. It also shows how much a $1,000 investment would be worth at the close of the period, assuming actual returns and expenses.


Expenses and Value of a $1,000 Investment

COMPARING YOUR FUND’S EXPENSES
WITH THOSE OF OTHER FUNDS (Unaudited)

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 April 30, 2020

	Investor Shares	Class I
Expense paid per $1,000^†	$2.51	$1.26
Ending value (after expenses)	$1,022.38	$1,023.62
^†Expenses are equal to the fund’s annualized expense ratio of .50% for Investor Shares and .25% for Class I, multiplied by the average account value over the period, multiplied by 182/366 (to reflect the one-half year period).

NOTES TO FINANCIAL STATEMENTS (Unaudited)

NOTE 1—Significant Accounting Policies:

BNY Mellon Midcap Index Fund, Inc. (the “fund”), which is registered under the Investment Company Act of 1940, as amended (the “Act”), is a non-diversified open-end management investment company. The fund’s investment objective is to seek to match the performance of the S&P’sMidCap 400^® Index. 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.

BNY Mellon Securities Corporation (the “Distributor”), a wholly-owned subsidiary of the Adviser, is the distributor of the fund’s shares, which are sold without a sales charge. The fund is authorized to issue 300 million shares of $.001 par value Common Stock. The fund currently has authorized two classes of shares: Investor shares (200 million shares authorized) and Class I (100 million shares authorized). Investor shares are sold primarily to retail investors through financial intermediaries and bear Shareholder Services Plan fees. Class I shares are sold at net asset value per share generally to institutional investors. Other differences between the classes include the services offered to and the expenses borne by each class, 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.

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 fund enters 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).

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 equity securities are valued at the last sales price on the securities exchange or national securities market on which such securities are primarily traded. Securities listed on the National Market System for which market quotations are available are valued at the official closing price or, if there is no official closing price that day, at the last sales price. For open short positions, asked prices are used for valuation purposes. Bid price is used when no asked price is available. Registered investment companies that are not traded on an exchange are valued at their net asset value. All of the preceding securities are generally categorized within Level 1 of the fair value hierarchy.

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

Securities not listed on an exchange or the national securities market, or securities for which there were no transactions, are valued at the average of the most recent bid and asked prices. U.S. Treasury Bills are valued at the mean price between quoted bid prices and asked prices by an independent pricing service (the “Service”) approved by the fund’s Board of Directors (the “Board”). These securities are generally categorized within Level 2 of the fair value hierarchy.

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

Fair valuing of securities may be determined with the assistance of a pricing service using calculations based on indices of domestic securities and other appropriate indicators, such as prices of relevant American Depository Receipts and futures. Utilizing these techniques may result in transfers between Level 1 and Level 2 of the fair value hierarchy.

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 (for example, a foreign exchange or market), 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 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.

Futures, which are traded on an exchange, are valued at the last sales price on the securities exchange on which such securities are primarily traded or at the last sales price on the national securities market on each business day and are generally categorized within Level 1 of the fair value hierarchy.

The following is a summary of the inputs used as of April 30, 2020 in valuing the fund’s investments:


	Level 1 - Unadjusted Quoted Prices	Level 2 – Other Significant Observable Inputs	Level 3 - Significant Unobservable Inputs	Total
Assets ($)
Investments in Securities:^†
Equity Securities— Common Stocks	1,975,694,109	-	-	1,975,694,109
Investment Companies	26,003,240	-	-	26,003,240
U.S. Treasury Securities	-	2,212,277	-	2,212,277
Other Financial Instruments:
Futures^††	460,407	-	-	460,407

^†See Statement of Investments for additional detailed categorizations, if any.
^††Amount shown represents unrealized appreciation (depreciation) at period end, but only variation margin on exchanged traded and centrally cleared derivatives, if any, are reported in the Statement of Assets and Liabilities.

(b) Foreign Taxes: The fund may be subject to foreign taxes (a portion of which may be reclaimable) on income, stock dividends, realized and unrealized capital gains on investments or certain foreign currency transactions. Foreign taxes are recorded in accordance with the fund understanding of the applicable foreign tax regulations and rates that exist in the foreign jurisdictions in which the fund invest. These foreign taxes, if any, are paid by the fund and are reflected in the Statements of Operations. Foreign taxes payable or deferred as of April 30, 2020, if any, are disclosed in the fund’s Statements of Assets and Liabilities.

(c) 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. Dividend income is recognized on the ex-dividend date and interest income, including, where applicable, accretion of discount and amortization of premium on investments, is recognized on the accrual basis.

Pursuant to a securities lending agreement with The Bank of New York Mellon, a subsidiary of BNY Mellon and an affiliate of the Adviser, the fund may lend securities to qualified institutions. It is the fund’s policy that, at origination, all loans are secured by collateral of at least 102% of the value of U.S. securities loaned and 105% of the value of foreign securities loaned. Collateral equivalent to at least 100% of the market value of securities on loan is maintained at all times. Collateral is either in the form of cash, which can be invested in certain money market mutual funds managed by the Adviser, or U.S. Government and Agency securities. The fund is entitled to receive all dividends, interest and distributions on

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

securities loaned, in addition to income earned as a result of the lending transaction. Should a borrower fail to return the securities in a timely manner, The Bank of New York Mellon is required to replace the securities for the benefit of the fund or credit the fund with the market value of the unreturned securities and is subrogated to the fund’s rights against the borrower and the collateral. Additionally, the contractual maturity of security lending transactions are on an overnight and continuous basis. During the period ended April 30, 2020, The Bank of New York Mellon earned $73,320 from the lending of the fund’s portfolio securities, pursuant to the securities lending agreement.

(d) Affiliated issuers: Investments in other investment companies advised by the Adviser are considered “affiliated” under the Act.

(e) Risk: Certain events particular to the industries in which the fund’s investments conduct their operations, as well as general economic, political and public health conditions, may have a significant negative impact on the investee’s operations and profitability. 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 worldwide. 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. To the extent the fund may overweight its investments in certain countries, companies, industries or market sectors, such positions will increase the fund’s exposure to risk of loss from adverse developments affecting those countries, companies, industries or sectors.

(f) Dividends and distributions to shareholders: Dividends and distributions are recorded on the ex-dividend date. Dividends from investment income-net and 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.

(g) Federal income taxes: It is the policy of the fund to continue to qualify as a regulated investment company, if such qualification is in the best interests of its shareholders, by complying with the applicable provisions of the Code, and to make distributions of taxable 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 April 30, 2020, 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 April 30, 2020, the fund did not incur any interest or penalties.

Each tax year in the three-year period ended October 31, 2019 remains subject to examination by the Internal Revenue Service and state taxing authorities.

The tax character of distributions paid to shareholders during the fiscal year ended October 31, 2019 was as follows: ordinary income $57,653,854 and long-term capital gains $295,626,427. The tax character of current year distributions will be determined at the end of the current fiscal year.

NOTE 2—Bank Lines of Credit:

The fund participates with other long-term open-end funds managed by the Adviser in a $927 million 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”), 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 $747 million and is available to all long-term open-ended funds, including the fund, and (ii) Tranche B is an amount equal to $180 million and is available only to BNY Mellon Floating Rate Income Fund, a series of BNY Mellon Investment Funds IV, Inc. Prior to March 11, 2020, the Citibank Credit Facility was $1.030 billion with Tranche A available in an amount equal to $830 million and Tranche B available in an amount equal to $200 million. 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.

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

The average amount of borrowings outstanding under the Facilities during the period ended April 30, 2020 was approximately $70,880 with a related weighted average annualized interest rate of 1.67%.

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 .25% of the value of the fund’s average daily net assets and is payable monthly. Out of its fee, the Adviser pays all of the expenses of the fund except management fees, Shareholder Services Plan fees, brokerage fees and commissions, taxes, interest expense, commitment fees on borrowings, fees and expenses of the interested Directors (including counsel fees) and extraordinary expenses. In addition, the Adviser required to reduce its fee in an amount equal to the fund’s allocable portion of fees and expenses of the non-interested Directors (including counsel fees). During the period ended April 30, 2020, fees reimbursed by the Adviser amounted to $141,300.

(b) Under the Shareholder Services Plan, Investor shares pay the Distributor at an annual rate of .25% 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, such as recordkeeping and sub-accounting services. 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 April 30, 2020, the fund was charged $2,159,952 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 components of “Due to BNY Mellon Investment Adviser, Inc. and affiliates” in the Statement of Assets and Liabilities consist of: management fees of $382,879 and Shareholder Services Plan fees of $271,640, which are offset against an expense reimbursement currently in effect in the amount of $33,800.

(c) Each Board member also serves as a Board member of other funds in the BNY Mellon Family of Funds complex. Annual retainer fees and attendance fees are allocated to each fund based on net assets.

NOTE 4—Securities Transactions:

The aggregate amount of purchases and sales of investment securities, excluding short-term securities and futures, during the period ended April 30, 2020, amounted to $151,592,971 and $522,165,950, respectively.

Derivatives: A derivative is a financial instrument whose performance is derived from the performance of another asset. Each type of derivative instrument that was held by the fund during the period ended April 30, 2020 is discussed below.

Futures: In the normal course of pursuing its investment objective, the fund is exposed to market risk, including equity price risk, as a result of changes in value of underlying financial instruments. The fund invests in futures in order to manage its exposure to or protect against changes in the market. A futures contract represents a commitment for the future purchase or a sale of an asset at a specified date. Upon entering into such contracts, these investments require initial margin deposits with a counterparty, which consist of cash or cash equivalents. The amount of these deposits is determined by the exchange or Board of Trade on which the contract is traded and is subject to change. Accordingly, variation margin payments are received or made to reflect daily unrealized gains or losses which are recorded in the Statement of Operations. When the contracts are closed, the fund recognizes a realized gain or loss which is reflected in the Statement of Operations. There is minimal counterparty credit risk to the fund with futures since they are exchange traded, and the exchange guarantees the futures against default. Futures open at April 30, 2020 are set forth in the Statement of Futures.

The following summarizes the average market value of derivatives outstanding during the period ended April 30, 2020:


		Average Market Value ($)
Equity futures		20,772,279

At April 30, 2020, accumulated net unrealized appreciation on investments inclusive of derivative contracts was $376,683,897, consisting of $677,803,346 gross unrealized appreciation and $301,119,449 gross unrealized depreciation.

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

At April 30, 2020, the cost of investments inclusive of derivative contracts for federal income tax purposes was substantially the same as the cost for financial reporting purposes (see the Statement of Investments).

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

At a meeting of the fund’s Board of Directors held on February 10-11, 2020, the Board considered the renewal of 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 several 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, including the fund. 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. The Board also considered portfolio management’s brokerage policies and practices (including policies and practices regarding soft dollars) and the standards applied in seeking best execution.

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 retail no-load S&P Midcap 400 Index funds (the “Performance Group”) and with a broader group of retail and institutional S&P Midcap 400 Index funds (the “Performance Universe”), all for various periods ended December 31, 2019, and (2) the fund’s actual and contractual management fees and total expenses with those of the same group of funds in the Performance Group (the “Expense Group”) and with a broader group of retail no-load S&P Midcap 400 Index funds, excluding outliers (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 the results of the comparisons and considered that the fund’s total return performance was at or below the Performance Group and Performance Universe median for all periods. The Board considered the relative proximity of the fund’s performance to the Performance Group and/or Performance Universe median in certain periods when performance was below median. It was noted that there were only three other funds in the Performance Group. 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 reviewed and considered the contractual management fee rate paid by the fund to the Adviser over the fund’s last fiscal year in light of the nature, extent and quality of the management services provided by the Adviser. The Board also reviewed the range of actual and contractual management fees and total expenses as a percentage of average net assets of the Expense Group and Expense Universe funds and discussed the results of the comparisons. Taking into account the fund’s “unitary” fee structure, the Board considered that the fund’s contractual management fee was lower than the Expense Group median contractual management fee, the fund’s actual management fee was slightly higher than the Expense Group and Expense Universe median actual management fee and the fund’s total expenses were lower than the Expense Group median and higher than the Expense Universe median total expenses.

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, noting the fund’s “unitary” fee structure. 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 excessive, given the services rendered and service levels provided by the Adviser and its affiliates. 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 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 the 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

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

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 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 the 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.
