FINANCIAL HIGHLIGHTS

The following tables describe the performance for each share class for the fiscal periods indicated. All information (except portfolio turnover rate) reflects financial results for a single fund share. Net asset value total return is calculated assuming an initial investment made at the net asset value at the beginning of the period, reinvestment of all dividends and distributions at net asset value during the period, and redemption at net asset value on the last day of the period. Net asset value total return includes adjustments in accordance with accounting principles generally accepted in the United States of America and as such, the net asset value for financial reporting purposes and the returns based upon those net asset values may differ from the net asset value and returns for shareholder transactions. The fund’s total returns do not reflect expenses associated with variable annuity or insurance contracts.

NOTES TO FINANCIAL STATEMENTS (Unaudited)

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 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”), serves as the fund’s investment adviser. Mellon Investments Corporation, an indirect wholly-owned subsidiary of BNY and an affiliate of the Adviser, serves as the fund’s index manager (the “Index Manager”).

The fund may operate as a non-diversified fund, as defined under the Act, as amended, to the approximate extent the S&P 500® Index is non-diversified, without shareholder approval. The fund may therefore operate as non-diversified solely as a result of a change in relative market capitalization or index weighting of one or more constituents of the index.

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 of 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 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:

Equity investments generally are valued at the last sale price on the day of valuation on the securities exchange or national securities market on which such securities primarily are traded. Securities listed on Nasdaq markets generally will be valued at the official closing price. If there are no transactions in a security, or no official closing prices for a Nasdaq market-listed security on that day, the security

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

will be valued at the average of the most recent bid and asked prices. Bid price is used when no asked price is available. Open short positions for which there is no sale price on a given day are valued at the lowest asked price. Investments in other open-end investment companies are valued at their reported net asset values (“NAVs”) each day. All of the preceding securities are generally categorized within Level 1 of the fair value hierarchy.

Fair value of foreign equity securities may be determined with the assistance of a pricing service using correlations between the movement of prices of foreign securities and indexes of domestic securities and other appropriate indicators, such as closing market prices of relevant American Depositary Receipts and futures contracts. The valuation of a security based on this fair value process may differ from the security’s most recent closing price and from the prices used by other mutual funds to calculate their NAVs. Foreign securities held by a fund may trade on days when the fund does not calculate its NAV and thus may affect the fund’s NAV on days when investors will not be able to purchase or sell (redeem) fund shares. Utilizing these techniques may result in transfers between Level 1 and Level 2 of the fair value hierarchy.

Restricted securities, as well as securities or other assets for which recent market quotations or official closing prices are not readily available or are determined not to reflect accurately fair value (such as when the value of a security has been materially affected by events occurring after the close of the exchange or market on which the security is principally traded, but before the fund calculates its NAV), or which are not valued by one or more independent pricing services, are valued at fair value as determined in good faith based on procedures approved by the fund’s Board of Directors (the “Board”). Fair value of investments is determined by the Adviser, as the fund’s valuation designee pursuant to Rule 2a-5 under the Act, using such information as it deems appropriate under the circumstances. The factors that may be considered when fair valuing a security include 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. Using fair value to price investments may result in a value that is different from a security’s most recent closing price and from the prices used by other mutual funds to calculate their NAVs. These securities are either categorized within Level 2 or 3 of the fair value hierarchy depending on the relevant inputs used.

Futures contracts will be valued at the most recent settlement price and are generally categorized within Level 1 of the fair value hierarchy.

The following is a summary of the inputs used as of June 30, 2026 in valuing the fund’s investments:

	Level 1 - Unadjusted Quoted Prices	Level 2- Other Significant Observable Inputs	Level 3- Significant Unobservable Inputs	Total

†	See Schedule of Investments for additional detailed categorizations, if any.
††	Amount shown represents unrealized appreciation (depreciation) at period end, but only variation margin on exchange-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 applicable foreign tax regulations and rates that exist in the foreign jurisdictions in which the fund invests. These foreign taxes, if any, are paid by the fund and are reflected in the Statement of Operations, if applicable. Foreign taxes payable or deferred or those subject to reclaims as of June 30, 2026, if any, are disclosed in the fund’s Statement 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

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

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 BNY, 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. Any non-cash collateral received cannot be sold or re-pledged by the fund, except in the event of borrower default, and is not reflected in the Statement of Assets and Liabilities. The securities on loan, if any, are also disclosed in the fund’s Schedule of Investments. 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, BNY 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 June 30, 2026, BNY earned $3,019 from the lending of the fund’s portfolio securities, pursuant to the securities lending agreement.

For financial reporting purposes, the fund elects not to offset assets and liabilities subject to a securities lending agreement, if any, in the Statement of Assets and Liabilities. Therefore, all qualifying transactions are presented on a gross basis in the Statement of Assets and Liabilities. As of June 30, 2026, the fund had securities lending and the impact of netting of assets and liabilities and the offsetting of collateral pledged or received, if any, based on contractual netting/set-off provisions in the securities lending agreement are detailed in the following table:

Assets ($)
Gross amount of securities loaned, at value, as disclosed in the Statement of Assets and Liabilities	25,965,150
Collateral (received)/posted not offset in the Statement of Assets and Liabilities	(25,965,150 )†
Net amount	-

†

The value of the related collateral received by the fund exceeded the value of the securities loaned by the fund pursuant to the securities lending agreement. In addition,

the value of collateral may include pending sales that are also on loan. See Schedule of Investments for detailed information regarding collateral received for open

securities lending.

(d) Affiliated issuers: Investments in other investment companies or equity securities advised by the Adviser are considered “affiliated” under the Act. Such equity investments were made according to the representative portion of the S&P 500® Index. The market values of these investments at June 30, 2026 are listed in the Schedule of Investments.

(e) Market Risk: The value of the securities in which the fund invests may be affected by political, regulatory, economic and social developments, and developments that impact specific economic sectors, industries or segments of the market. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or fixed-income markets may negatively affect many issuers, which could adversely affect the fund. Global economies and financial markets are becoming increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers in a different country, region or financial market. These risks may be magnified if certain events or developments adversely interrupt the global supply chain; in these and other circumstances, such risks might affect companies world-wide. Local, regional or global events such as war, military conflicts, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, recessions, elevated levels of government debt, changes in trade regulation or economic sanctions, internal unrest and discord, or other events could have a significant impact on the fund and its investments.

Indexing Strategy Risk: The fund uses an indexing strategy. It does not attempt to manage market volatility, use defensive strategies or reduce the effects of any long-term periods of poor index performance. The correlation between fund and index performance may be affected by the fund’s expenses, changes in securities markets, changes in the composition of the index and the timing of purchases and redemptions of fund shares.

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

Non-Diversification Risk: Because the fund seeks to closely track the composition of the index, from time to time, more than 25% of the fund’s total assets may be invested in issuers representing more than 5% of the fund’s total assets due to an index rebalance or market movement, which would result in the fund being non-diversifed under the Act, as amended. A non-diversified fund may invest a greater portion of its assets in securities of a smaller number of individual issuers than a diversified fund. As a result, the fund’s performance may be more vulnerable to changes in the market value of a single issuer or group of issuers and more susceptible to risks associated with a single economic, political or regulatory occurrence than a diversified fund.

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

(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 June 30, 2026, 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 June 30, 2026, the fund did not incur any interest or penalties.

Each tax year in the three-year period ended December 31, 2025 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 December 31, 2025 were as follows: ordinary income $37,048,993 and long-term capital gains $196,979,688. The tax character of current year distributions will be determined at the end of the current fiscal year.

(h) Operating segment reporting: In accordance with FASB Accounting Standards Update 2023-07, Segment Reporting (Topic 280) - Improvements to Reportable Segment Disclosures (“ASU 2023-07”), the fund has operated and been managed as a single reportable segment, generating returns through dividends, interest, and/or gains from investments aligned with its single stated investment objective as outlined in the fund’s prospectus. The fund’s accounting policies are consistent with those described in these Notes to Financial Statements. The chief operating decision maker (“CODM”) is represented by BNY Investments and is comprised of Senior Management and Directors of BNY Investments. The CODM considers the net increase in net assets resulting from operations when deciding whether to purchase additional investments or make distributions to shareholders. Detailed financial information for the fund is presented in these financial statements, including total assets and liabilities in the Statement of Assets and Liabilities, investments held in the Schedule of Investments, results of operations and significant segment expenses in the Statement of Operations, and additional performance information—such as total return, portfolio turnover, and ratios—in the Financial Highlights.

NOTE 2—

Bank Lines of Credit:

The fund participates with other long-term open-end funds managed by the Adviser in a $738 million unsecured credit facility led by Citibank, N.A. (the “Citibank Credit Facility”) and a $300 million unsecured credit facility provided by BNY (the “BNY 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 $618 million and is available to all long-term open-ended funds, including the fund, and (ii) Tranche B is an amount equal to $120 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 BNY 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 June 30, 2026, the fund was charged $46,406 for interest expense. These fees are included in Interest expense in the Statement of Operations. The average amount of borrowings outstanding under the Citibank Credit Facility during the period ended June 30, 2026 was approximately $2,029,282 with a related weighted average annualized interest rate of 4.61%. As of June 30, 2026, the fund has no outstanding loan balance from either Facility.

NOTE 3—

Management Fee, Index-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 .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 Bank of New York Mellon (the “Custodian”), a subsidiary of BNY and an affiliate of the Adviser, for its services to the fund, excluding services related to shareholder reporting and regulatory services for the fund.

(b) Under the distribution plan adopted pursuant to Rule 12b-1 under the Act (the “Distribution Plan”), 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 June 30, 2026, Service shares were charged $78,353 pursuant to the Distribution Plan.

(c) Under the shareholder services plan (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 June 30, 2026, Initial shares were charged $6,200 pursuant to the Shareholder Services Plan.

The fund has an arrangement with BNY Mellon Transfer, Inc., (the “Transfer Agent”), a subsidiary of BNY and an affiliate of the Adviser, whereby the fund may receive earnings credits when positive cash balances are maintained, which are used to offset Transfer Agent fees. For financial reporting purposes, the fund includes transfer agent net earnings credits, if any, as an expense offset in the Statement of Operations.

The fund has an arrangement with the Custodian whereby the fund will receive interest income or be charged overdraft fees when cash balances are maintained. For financial reporting purposes, the fund includes this interest income and overdraft fees, if any, as interest income in the Statement of Operations.

The fund compensates the Transfer Agent, under a transfer agency agreement, for providing transfer agency and cash management services for the fund. The majority of Transfer Agent 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 June 30, 2026, the fund was charged $607 for transfer agency services. These fees are included in Shareholder servicing costs in the Statement of Operations.

During the period ended June 30, 2026, the fund was charged $20,180 for services performed by the fund’s Chief Compliance Officer and his staff. These fees are included in Chief Compliance Officer fees in the Statement of Operations.

The fund compensates the Custodian for providing shareholder reporting and regulatory services for the fund. These fees are included in shareholder and regulatory reports service fees in the Statement of Operations. During the period ended June 30, 2026, the Custodian was compensated $9,000 for financial reporting and regulatory services.

The components of “Due to BNY Mellon Investment Adviser, Inc. and affiliates” in the Statement of Assets and Liabilities consist of: management fee of $641,688, Distribution Plan fees of $13,418, Chief Compliance Officer fees of $5,768, Transfer Agent fees of $307 and shareholder and regulatory reports service fees of $9,000.

(d) Each board member of the fund 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—

The aggregate amount of purchases and sales of investment securities, excluding short-term securities and derivatives, during the period ended June 30, 2026, amounted to $42,982,226 and $395,250,601, 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 June 30, 2026 is discussed below.

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

Broker Deposits: The amount included in Cash collateral held by broker in the Statement of Asset and Liabilities represents cash balances that are held by one or more brokers, including collateral required for derivative contracts. Any income earned on cash balances held by a broker is recorded as interest income to the fund.

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 June 30, 2026 are set forth in the fund’s Schedule of Investments.

The following tables show the fund’s exposure to different types of market risk as it relates to the Statement of Assets and Liabilities and the Statement of Operations, respectively.

Statement of Operations as Directors’ fees and expenses and Chief Compliance Officer fees, respectively. The aggregate amount of Directors’ fees and expenses and Chief Compliance Officer fees paid by the fund during the period was $137,812.

Item 11. Statement Regarding Basis for Approval of Investment Advisory Contracts (Unaudited)

At a meeting of the fund’s Board of Directors (the “Board”) held on March 5-6, 2026, 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, and the Index Management Agreement (together with the Management Agreement, the “Agreements”), pursuant to which Mellon Investments Corporation (the “Index Manager”) provides day-to-day management of the fund’s investments. 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 and Index Manager. In considering the renewal of the Agreements, 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 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 fund complex (such as 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, as well as the Adviser’s supervisory activities over the Index Manager.

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 based on classifications provided by Thomson Reuters Lipper (“Lipper”), which included information comparing (1) the performance of the fund’s Initial shares with the performance of a group of S&P 500 index funds underlying variable insurance products (“VIPs”) selected by Broadridge as comparable to the fund (the “Performance Group”) and with a broader group of funds consisting of all S&P 500 index funds underlying VIPs (the “Performance Universe”), all for various periods ended December 31, 2025, 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 funds consisting of S&P 500 index funds underlying VIPs with similar 12b-1/non-12b-1 structures, 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.

Performance Comparisons. 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 and the end date selected. The Board also considered the fund’s performance in light of overall financial market conditions. The Board discussed with representatives of the Adviser the results of the comparisons and considered that the fund’s total return performance was above the Performance Group and Performance Universe medians for all periods. 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 noted that the fund had a four star rating for each of the three-, five- and ten-year periods and a four star overall rating from Morningstar based on Morningstar’s risk-adjusted return measures.

Management Fee and Expense Ratio Comparisons. The Board reviewed and considered the contractual management fee rate payable by the fund to the Adviser in light of the nature, extent and quality of the management services and index management services provided by the Adviser and Index Manager, respectively. In addition, the Board reviewed and considered the actual management fee rate paid by the fund over the fund’s last fiscal year. 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.

Item 11. Statement Regarding Basis for Approval of Investment Advisory Contracts (Unaudited) (continued)

The Board considered that the fund’s contractual management fee was slightly higher than the Expense Group median contractual management fee, the fund’s actual management fee was slightly higher than the Expense Group median and slightly higher than the Expense Universe median actual management fee, and the fund’s total expenses were lower than the Expense Group median and lower than the Expense Universe median total expenses. The Board noted, however, that the Expense Group included funds that charged 12b-1 fees and/or non-12b-1 service fees, whereas, the fund’s Initial shares are not subject to such fees. Had the 12b-1/non-12b-1 fees applicable to the fund’s Service shares been included in the comparison with the Expense Group, the fund’s total expenses would have been higher 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 paid to the Adviser or the Index Manager 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. Representatives of the Adviser noted that there were no other funds advised by the Adviser that are in the same Lipper category as the fund.

The Board considered the fee payable to the Index Manager in relation to the fee payable to the Adviser by the fund and the respective services provided by the Index Manager and the Adviser. The Board also took into consideration that the Index Manager’s fee is paid by the Adviser, out of its fee from the fund, and not the fund.

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 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 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 Agreements, considered in relation to the mix of services provided by the Adviser and the Index Manager, including the nature, extent and quality of such services, supported the renewal of the Agreements 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, as a result of shared and allocated costs among funds in the BNY 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 and the Index Manager from acting as investment adviser and index manager, respectively, 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 Agreements. 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 and the Index Manager are satisfactory and appropriate.

●The Board was satisfied with the fund’s performance.

●The Board concluded that the fees paid to the Adviser and the Index Manager 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 Management 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 Agreements, 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 and the Index Manager, of the Adviser and the Index Manager and the services provided to the fund by the Adviser and the Index Manager. 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 Agreements, 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 Agreements for the fund, or substantially similar agreements for other BNY 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 its consideration of the fund’s arrangements, or substantially similar arrangements for other BNY funds that the Board oversees, in prior years. The Board determined to renew the Agreements.
