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

Dear Shareholder:

We are pleased to present this annual report for BNY Mellon Stock Index Fund, Inc. (formerly, Dreyfus Stock Index Fund, Inc.), covering the 12-month period from January 1, 2019 through December 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.

In January 2019, a pivot in stance from the U.S. Federal Reserve (the “Fed”) helped stimulate a rebound across equity markets that continued into the second quarter of the year. However, escalating trade tensions disrupted equity markets in May. The dip was short-lived, as markets rose once again 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. Stocks rebounded in September and continued an upward path through most of October 2019, bolstered by central bank policy and consistent consumer spending. The rally generally continued through the end of the period, supported in part by an announcement from President Trump 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 the period.

In fixed-income markets, the year began with a recovery from the prior months’ volatility. After the Fed’s supportive statements in January 2019, other developed-market central banks followed suit and reiterated their abilities to buttress flagging growth rates by continuing accommodative policies. The Fed cut rates in July, September and October 2019, for a total 75 basis point reduction in the federal funds rate during the 12 months. Rates across much of the Treasury curve saw a slight increase during the month of November, and the long end of the curve rose in December. The yield curve steepened during the latter portion of the period. However, demand for fixed-income instruments during the year was strong, which helped to support positive bond market returns.

We believe that over the near term, the outlook for the U.S. remains positive, but we 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 January 1, 2019 through December 31, 2019, 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 12-month period ended December 31, 2019, BNY Mellon Stock Index Fund, Inc.’s (formerly, Dreyfus Stock Index Fund, Inc.) Initial Shares produced a total return of 31.18%, and its Service Shares produced a total return of 30.84%.¹In comparison, the S&P 500® Index (the “Index”), the fund’s benchmark, produced a total return of 31.46% for the same period.^2,3

U.S. equities gained over the reporting period, in an environment of moderate economic growth and supportive central bank policy. The difference in returns between the fund and the Index 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 total return of the Index. To pursue its goal, the fund generally is fully invested in stocks included in the Index. The fund generally invests in all 500 stocks in the Index in proportion to their weighting in the Index. The fund may also use stock index futures contracts, whose performance is tied to the Index, or invest in exchange-traded funds, typically when the fund’s available cash balances cannot otherwise be efficiently or effectively invested directly.

Markets Pivot on Central Bank Statements and Trade Policy

January 2019 marked a turnaround in the markets. Talk of a potential trade deal between the U.S. and China helped fuel investor optimism, as equity prices recovered from fourth quarter 2018 volatility. At its first meeting of the year, the Federal Reserve (the “Fed”) emphasized its focus on data as a primary driver for rate-hike decisions, and its ability to suspend additional rate increases when the data is not supportive. These sentiments reassured investors of central bankers’ commitments to support flagging growth. In addition, the European Central Bank announced it would provide additional stimulus to support the eurozone economy. China also announced plans to stoke its slowing economic growth rate. The rebound continued throughout the month of January 2019, and equity markets maintained an upward trajectory through April 2019. However, renewed trade tensions between the U.S. and China in May caused stocks to pull back once again. The dip was short-lived, as markets rose once again in June.

However, concerns over slowing economic growth continued, and inflation floundered. The Fed decided to provide additional stimulus by cutting the federal funds rate. It did so three times during the period, each time by 25 basis points. These cuts occurred in July, September and October. Supported by rate cuts, moderate economic growth and optimism regarding a preliminary trade agreement with China, equity markets went on to post solid gains during the last several months of the year.

According to the S&P family of indices, large-cap stocks generally outperformed their mid- and small-cap counterparts during the period.

DISCUSSION OF FUND PERFORMANCE(Unaudited) (continued)

Technology Companies Led U.S. Large-Cap Markets

During the reporting period, the S&P 500 Index posted strong results. All sectors within the Index posted positive returns. Information technology was the best performing sector in the Index. Semiconductor and semiconductor equipment companies were particularly strong performers. Technologies such as cloud computing and autonomous vehicles supported demand for these chips. In addition, the rollout of 5G technology also provided an additional market for many products manufactured by chip makers and other technology companies. Elsewhere in the sector, payments processing companies, such as Mastercard and Visa, were among the top performers. Apple drove sector returns. The financials sector was a standout performer. Banks benefited from the low rate environment, high refinancing activity and low loan default rates. The Fed’s cuts to the federal funds rate helped banks by reducing the costs associated with overnight lending, as did high deposit rates from consumers, which reduced banks’ need to borrow. Many U.S. banks also passed federal stress tests, contributing to rising market values of banks. The communication services sector benefited from stock performance in the interactive media industry. Companies such as Facebook, Alphabet andTripAdvisor helped lead the market. These companies have access to wide audiences and are capable of advertising to large quantities of people. In addition, telecommunication companies, particularly those investing in satellite technology and streaming services, enjoyed strong results.

Some sectors lagged the broader market during the period. In the materials sector, construction materials and metals and mining companies experienced constrained results. Concerns about growth rates in China hurt the demand for metals stocks. A comparatively strong dollar also helped to reduce demand for these U.S. products overseas. Health care companies also tended to lag the broader market. Ongoing discussions over drug prices and health care provided a headwind for the stock prices of many health care providers and pharmaceuticals companies during parts of the year. In addition, the strong dollar hurt exports of drugs to many emerging- markets consumers. Lastly, energy companies, particularly exploration and production companies, lagged the broader market, due to soft oil prices during the period, and depressed company returns. Natural gas companies also saw low production rates during the period.

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 the U.S. economy remains supported by a strong labor market and sound corporate balance sheets. However, the market’s currently constructive conditions could be undermined by unexpected political and economic developments. As always, we have continued to monitor the factors considered by 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. The fund’s performance does not reflect the deduction of additional charges and expenses imposed in connection with investing in variable insurance contracts, which will reduce returns.

²Source: Lipper Inc. — The S&P 500^®Index is widely regarded as the best single gauge of large-cap U.S. equities. The index includes 500 leading companies and captures approximately 80% coverage of available market capitalization. Investors cannot invest directly in any index.

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.

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.

The fund is only available as a funding vehicle under variable life insurance policies or variable annuity contracts issued by insurance companies. Individuals may not purchase shares of the fund directly. A variable annuity is an insurance contract issued by an insurance company that enables investors to accumulate assets on a tax-deferred basis for retirement or other long-term goals. The investment objective and policies of BNY Mellon Stock Index Fund, Inc. made available through insurance products may be similar to those of other funds managed by BNY Mellon Investment Adviser, Inc. However, the investment results of the fund may be higher or lower than, and may not be comparable to, those of any other BNY Mellon Investment Adviser, Inc. fund.

NOTES TO FINANCIAL STATEMENTS

NOTE 1—Significant Accounting Policies:

BNY Mellon Stock 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 is only offered to separate accounts established by insurance companies to fund variable annuity contracts and variable life insurance policies. The fund’s investment objective is to seek to match the total return of the S&P 500^® 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. Effective January 2, 2019, BNY Mellon Asset Management North America Corporation, a wholly-owned subsidiary of BNY Mellon and an affiliate of the Adviser, which serves as the fund’s index manager, was renamed Mellon Investments Corporation (the “Index Manager”).

Effective June 3, 2019, the fund changed its name from Dreyfus Stock Index Fund, Inc. to BNY Mellon Stock Index Fund, Inc. 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, which are sold without a sales charge. The fund is authorized to issue 400 million shares of $.001 par value Common Stock in each of the following classes of shares: Initial shares (250 million shares authorized) and Service shares (150 million shares authorized). Initial shares are subject to a Shareholder Services Plan fee and Service shares are subject to a Distribution Plan fee. Each class of shares has identical rights and privileges, except with respect to the Distribution Plan, Shareholder Services Plan 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.

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

NOTES TO FINANCIAL STATEMENTS(continued)

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).

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.

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 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.

NOTES TO FINANCIAL STATEMENTS(continued)

Investments denominated in foreign currencies are translated to U.S. dollars at the prevailing rates of exchange.

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 December 31, 2019in valuing the fund’s investments:

^† See Statement of Investments for additional detailed categorizations, if any.
^†† Amount shown represents unrealized appreciation 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 currency transactions: The fund does not isolate that portion of the results of operations resulting from changes in foreign exchange rates on investments from the fluctuations arising from changes in the market prices of securities held. Such fluctuations are included with the net realized and unrealized gain or loss on investments.

Net realized foreign exchange gains or losses arise from sales of foreign currencies, currency gains or losses realized on securities transactions between trade and settlement date, and the difference between the amounts of dividends, interest and foreign withholding taxes recorded on the fund’s books and the U.S. dollar equivalent of the amounts actually received or paid. Net unrealized foreign exchange gains and losses arise from changes in the value of assets and liabilities other than investments resulting from changes in exchange rates. Foreign currency gains and losses on foreign currency transactions are also included with net realized and unrealized gain or loss on investments.

(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 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 December 31, 2019, The Bank of New York Mellon earned $28,970 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) Dividends and distributions to shareholders:Dividends and distributions are recorded on the ex-dividend date. Dividends from investment income-net are normally declared and paid quarterly. 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.

(f) 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

NOTES TO FINANCIAL STATEMENTS(continued)

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 December 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 December 31, 2019, the fund did not incur any interest or penalties.

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

At December 31, 2019, the components of accumulated earnings on a tax basis were as follows: undistributed ordinary income $4,592,733, undistributed capital gains $160,461,215 and unrealized appreciation $1,788,904,694.

The tax character of distributions paid to shareholders during the fiscal periods ended December 31, 2019 and December 31, 2018 were as follows: ordinary income $42,207,571 and $45,258,635, and long-term capital gains $126,487,031 and $54,122,767, respectively.

(g) New Accounting Pronouncements: 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 eliminates, adds and modifies certain disclosure requirements for fair value measurements. The adoption of ASU 2018-13 had no impact on the operations of the fund for the period ended December 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”), 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.

The average amount of borrowings outstanding under the Facilities during the period ended December 31, 2019 was approximately $127,120 with a related weighted average annualized interest rate of 3.10%.

NOTE 3—Management Fee, Index-Management Fee and Other Transactions with Affiliates:

(a)Pursuant to a management agreement (the “Agreement”) with the Adviser, the management fee is computed at the annual rate of .245% of the value of the fund’s average daily net assets and is payable monthly.

Pursuant to an index-management agreement (the “Index Agreement”), the Adviser has agreed to pay the Index Manager a monthly index-management fee at the annual rate of .095% of the value of the fund’s average daily net assets. Pursuant to the Index Agreement, the Index Manager pays the Custodian for its services to the fund.

(b)Under the Distribution Plan adopted pursuant to Rule 12b-1 under the Act, Service shares pay the Distributor for distributing its shares, for servicing and/or maintaining Service shares’ shareholder accounts and for advertising and marketing for Service shares. The Distribution Plan provides for payments to be made at an annual rate of .25% of the value of the Service shares’ average daily net assets. The Distributor may make payments to Participating Insurance Companies and to brokers and dealers acting as principal underwriter for their variable insurance products. The fees payable under the Distribution Plan are payable without regard to actual expenses incurred. During the period ended December 31, 2019,Service shares were charged $471,333 pursuant to the Distribution Plan.

(c) Under the Shareholder Services Plan, Initial shares reimburse the Distributor at an amount not to exceed an annual rate of .25% of the value of its average daily net assets for certain allocated expenses with respect to servicing and/or maintaining Initial shares’ shareholder accounts. During the period ended December 31, 2019, Initial shares were charged 7,226 pursuant to the Shareholder Services Plan.

The fund has an arrangement with the transfer agent whereby the fund may receive earnings credits when positive cash balances are maintained, which are used to offset transfer agency fees. The fund had an arrangement with the custodian to receive earnings credits when positive cash balances were maintained, which were used to offset custody fees.

NOTES TO FINANCIAL STATEMENTS(continued)

Effective February 1, 2019, the arrangement with the custodian changed whereby the fund will no longer receive earnings credits to offset its custody fees and will receive interest income or overdraft fees going forward. 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 December 31, 2019, the fund was charged $1,333 for transfer agency services. These fees are included in Shareholder servicing costs in the Statement of Operations.

During the period ended December 31, 2019, the fund was charged $11,793 for services performed by the Chief Compliance Officer and his staff. These fees are included in Chief Compliance Officer fees 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 $538,185, Distribution Plan fees of $40,800, Shareholder Services Plan fees of $1,000, Chief Compliance Officer fees of $3,261 and transfer agency fees of $2,870.

(d) 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 December 31, 2019, amounted to $72,028,810 and $305,844,122, 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 December 31, 2019 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 December 31, 2019 are set forth in the Statement of Futures.

The following summarizes the average market value of derivatives outstanding duringthe period ended December 31, 2019:


		Average Market Value ($)
Equity futures		22,160,932

At December 31, 2019, the cost of investments for federal income tax purposes was $849,547,930; accordingly, accumulated net unrealized appreciation on investments was $1,788,904,694, consisting of $1,848,034,638 gross unrealized appreciation and $59,129,944 gross unrealized depreciation.

NOTE 5—Pending Legal Matters:

The fund and many other entities have been named as defendants in numerous pending litigations as a result of their participation in the leveraged buyout transaction (“LBO”) of the Tribune Company (“Tribune”).

The State Law Cases: In 2008, approximately one year after the Tribune LBO concluded, Tribune filed for bankruptcy protection under Chapter 11 of the Bankruptcy Code (the “Code”). Beginning in June 2011, Tribune creditors filed complaints in various courts, alleging that the payments made to shareholders in the LBO were “fraudulent conveyances” under state and/or federal law, and that the shareholders must return the payments they received for their shares (collectively, “the state law cases”). The state law cases were consolidated for pre-trial proceedings in the United States District Court for the Southern District of New York, under the captionIn re Tribune Company Fraudulent Conveyance Litigation(S.D.N.Y. Nos. 11-md-2296 and 12-mc-2296 (RJS) (“Tribune MDL”)). On September 23, 2013, the Court dismissed 50 cases, including at least one case in which the fund was a defendant. On September 30, 2013, plaintiffs

NOTES TO FINANCIAL STATEMENTS(continued)

appealed the District Court’s decision to the U.S. Court of Appeals for the Second Circuit. On March 29, 2016, the Second Circuit affirmed the dismissal on the ground that the plaintiffs’ claims were preempted by section 546(e) of the Code, which exempts qualified transfers that were made “by or to (or for the benefit of) . . . a financial institution.” The fund is a registered investment company, which the Code defines as a “financial institution.”

On September 9, 2016, Plaintiffs filed a petition forcertiorarito the U.S. Supreme Court. During the pendency of the plaintiffs’cert. petition, the Supreme Court ruled in another case,Merit Management Group, LP v. FTIConsulting, Inc. (“Merit Management”), that Section 546(e) does not exempt qualified transfers from avoidance that merely passed through “financial institutions,” though it does exempt “financial institutions” themselves, like the fund.

On May 15, 2018, in response to theMerit Management decision, the Second Circuit issued an Order in the State Law Cases that “the mandate in this case is recalled in anticipation of further panel review.”

On December 19, 2019, the Second Circuit issued an Amended and Corrected Opinion affirming dismissal of the constructive fraudulent transfer claims notwithstandingMerit Mgmt.,because there is an alternate basis for finding that the payments are safe-harbored under Section 546(e); namely, that, with respect to LBO payments, the Tribune Company is itself a “financial institution” because it was the customer of Computershare – a trust company and bank that acted as Tribune’s agent – and because all payments were made in connection with a securities contract.

On January 2, 2020, plaintiffs petitioned the Second Circuit for rehearing and rehearingen bancon numerous grounds, including that the panel rendered its decision using an incorrect construction of Section 546(e), improperly considered evidence, and an insufficiently developed factual record. Second Circuit rules state that parties opposing a petition for rehearing and rehearingen banc are not permitted to file a response unless requested by theCourt. As of January 24, 2020, the Second Circuit has not requested oppositions to plaintiffs’ motion.

TheFitzSimonsLitigation: On November 1, 2010, a case now styled,Mark S. Kirchner, as Litigation Trustee for the Tribune Litigation Trust v. FitzSimons, et al., S.D.N.Y. No. 12-cv-2652 (RJS) was filed (“theFitzSimons Litigation”). Among other things, the complaint sought recovery of alleged “fraudulent conveyances” from more than 5,000 Tribune shareholders (“Shareholder Defendants”), including the fund, that participated in the Tribune LBO. On May 23, 2014, the defendants filed a motion to dismiss, which the

Court granted on January 9, 2017. The plaintiff then sought leave to file an interlocutory appeal. On February 23, 2017, the Court entered an order stating that it would permit the plaintiff to file an interlocutory appeal after the Court decided other pending motions.

Effective November 1, 2018, Judge Denise Cote was assigned to the case when Judge Richard Sullivan was elevated to the Second Circuit.

On November 30, 2018, the Court issued an Opinion and Order resolving the remaining motions by dismissing most, but not all, of the claims asserted against the individual defendants.

In January 2019, various state law claims asserted against certain individual defendants were dismissed.

Between February and early April 2019, plaintiffs and certain defendants attempted to resolve the dispute through mediation, but ultimately decided to await the Second Circuit’s review of its May 29, 2016 decision before attempting to negotiate a settlement.

On April 4, 2019, plaintiff filed a motion to amend theFitzSimons complaint to add a claim for constructive fraudulent transfer from defendants subject to clawback under the Bankruptcy Code. On April 10, 2019, the affected defendants opposed the motion.

On April 23, 2019, Judge Cote denied plaintiff’s motion to amend the complaint to add a new constructive fraudulent transfer claim because such amendment would be futile and would result in substantial prejudice to the shareholder defendants given that the only claim against the shareholder defendants inFitzSimonshas been dismissed for over two years, subject to appeal. Judge Cote considered the amendment futile on the ground that constructive fraudulent transfer claims are barred by the safe harbor provision of Section 546(e), which defines “financial institution” to include, in certain circumstances, thecustomers of traditional financial institutions, including Tribune.

On July 12, 2019, the Trustee filed a notice of appeal to the Second Circuit from the April 23, 2019, decision denying leave to amend the complaint to add constructive fraudulent transfer claims. On July 15, 2019, the Trustee filed a corrected notice of appeal to remedy technical errors with the notice filed on July 12, 2019. Briefing on these matters began in January 2020, and is expected to be completed and fully submitted to the Second Circuit by June 2020.

At this stage in the proceedings, management does not believe that a loss is probable and, in any event, is unable to reasonably estimate the possible loss that may result.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and the Board of Directors of BNY Mellon Stock Index Fund, Inc. (formerly, Dreyfus Stock Index Fund, Inc.)

Opinion on the Financial Statements

We have audited the accompanying statement of assets and liabilities of BNY Mellon Stock Index Fund, Inc. (the “Fund”) (formerly, Dreyfus Stock Index Fund, Inc.), including the statements of investments, investments in affiliated issuers and futures, as of December 31, 2019, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, the financial highlights for each of the five years in the period then ended and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Fund at December 31, 2019, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and its financial highlights for each of the five years in the period then ended, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

These financial statements are the responsibility of the Fund’s management. Our responsibility is to express an opinion on the Fund’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Fund is not required to have, nor were we engaged to perform, an audit of the Fund’s internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting, but not for the purpose of expressing an opinion on the effectiveness of the Fund’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of December 31, 2019, by correspondence with the custodian and others or by other appropriate auditing procedures where replies from others were not received. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

We have served as the auditor of one or more investment companies in the BNY Mellon Family of Funds since at least 1957, but we are unable to determine the specific year.
