As of that date, all Class A Shares were redesignated as Class I Shares. At the same time, Class D Shares were redesignated Class A Shares. Trading symbols have not been changed nor have current eligibility rules or pricing structures. This redesignation of share classes does not impact your investment in any way. Investment Environment The first quarter of 2003 brought negative returns and extreme volatility. The U.S. markets lost ground consistently during the beginning of the quarter then spiked on news of the start of war with Iraq. The downtrend returned after investors realized that the conflict might last longer than anticipated, potentially curbing business spending. Most indexes finished the first quarter in negative territory. The second quarter of 2003 brought impressive gains and what some are calling a "bull rally." The U.S. markets rose consistently over the quarter, spurred by optimism that economic and profit growth will accelerate. On June 16, 2003, the S&P 500 Index closed above the 1,000 mark (at 1,010.74) for the first time since June 20, 2002. Most indexes finished the six-month period ended June 30, 2003 in positive territory, with the Dow Jones Industrial Average closing at 8,985.44, up 7.72% for the period, and the S&P 500 Index closing at 974.50, up 10.76% for the period. The NASDAQ Composite Index closed at 1,622.80, up an impressive 21.51%. Technology stocks have outperformed the broader market on expectations that companies in that sector will be among the first beneficiaries of an economic recovery. Portfolio Matters For the six months ended June 30, 2003, Merrill Lynch S&P 500 Index Fund's Class A and Class I Shares had total returns of +11.44% and +11.62%, respectively, compared to the unmanaged benchmark Standard & Poor's (S&P) 500 Index's total return of +11.76%. (Complete performance information can be found on page 4 of this report to shareholders.) The Fund met its objective of closely tracking the return of its benchmark. Value outperformed growth for the period, with the S&P 500 Barra Value Index returning +12.29% compared to the S&P 500 Barra Growth Index, which had a return of +11.25%. The top year-to-date (as of June 30, 2003) sector performer was information technology, up 17.40%, followed by consumer discretionary, up 16.94% and utilities, up 15.03%. The worst year-to-date sectors were consumer staples, up only 0.91%, telecommunications services, up 2.29% and materials, up 4.14%. (Sector returns shown are measured by those sectors in S&P 500 Index.) Market Review Investor confidence remained shaken early in 2003 with threats of terrorism, nuclear tensions in North Korea, and unexpectedly high unemployment. The war in Iraq left investors with inconsistent views about the market, and trading was reactionary to news from the front lines. However, markets rallied following the resolution of military affairs in Iraq, and investors became increasingly bullish about the outlook for equities. The rise was notable for all sectors and countries. It has been encouraging to see that the SARS virus appears to have been brought under control in Hong Kong, Singapore, China and, hopefully, Taiwan. Despite unstable markets, the Federal Reserve Board left interest rates unchanged at 1.25% at its January 29 and March 18 meetings. After leaving the rates unchanged again at its May 6 meeting, the Federal Reserve Board lowered its target for the Federal Funds rate by 25 basis points (.25%) to 1% at its June 25 meeting, bringing the rate to a 49-year low. The Federal Reserve Board continues to use an accommodative stance of monetary policy, coupled with an underlying growth in productivity, to provide ongoing support to economic activity. The modest 25 basis point cut rather than the expected 50 basis point cut leaves room for further Federal Reserve Board interest rate reductions in the future. In response to the Federal Reserve Board's decision, financial markets were initially disappointed, with long-term interest rates backing up sharply and stock prices falling. This movement will likely be moderated by the realization that the growth outlook will be strengthened. Economic Outlook Economic indicators for the current economy are ambiguous, but the economy may strengthen and produce strong results for the second half of 2003. Many of the geopolitical factors that may have exacerbated the slowdown in activity (war fears, higher oil prices, poor weather and SARS) have been largely resolved. While the economy is improving, the rate of change is only gradual. Data indicates that further policy stimulus will hit the economy in the second half of the year, but it is worth noting the lack of growth given the large cuts in interest rates already seen. Additionally, a key factor is the concern about whether consumers will continue to spend long enough to prop up the economy until a corporate spending cycle emerges. For the next quarter, the reaction by the economy to all the stimuli in the pipeline and the extent of the recovery is still ambiguous. Lower withholding taxes from paychecks and child tax credit checks position households on the receiving end of at least $30 billion from tax relief. This, coupled with a mortgage-refinancing wave continuing a high incentive to refinance, is indicative of an increase in consumer spending in the third quarter putting the economy on a recovery track. With that in mind, the portfolio is expected to continue to meet its objectives. In Conclusion We appreciate your investment in Merrill Lynch S&P 500 Index Fund, and we look forward to assisting you with your investment needs in the months and years ahead. Sincerely, /s/ Terry K. Glenn Terry K. Glenn President and Director/Trustee /s/ Richard J. Vella Richard J. Vella Vice President and Senior Portfolio Manager July 15, 2003 2 & 3 Merrill Lynch S&P 500 Index Fund, June 30, 2003 PERFORMANCE DATA About Fund Performance Effective April 14, 2003, Class A Shares were redesignated Class I Shares and Class D Shares were redesignated Class A Shares. Investors are able to purchase shares of the Fund, which offers two pricing alternatives: o Class A Shares do not incur a maximum initial sales charge or deferred sales charge and bear no ongoing distribution fee. In addition, Class A Shares are subject to an ongoing account maintenance fee of 0.25%. o Class I Shares do not incur a maximum initial sales charge (front-end load) or deferred sales charge and bear no ongoing distribution or account maintenance fees. Class I Shares are available only to eligible investors. None of the past results shown should be considered a representation of future performance. Performance results do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. Figures shown in each of the following tables assume reinvestment of all dividends and capital gains distributions at net asset value on the ex-dividend date. Investment return and principal value of shares will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. Dividends paid to each class of shares will vary because of the different levels of account maintenance, distribution and transfer agency fees applicable to each class, which are deducted from the income available to be paid to shareholders. The Fund's Administrator and the Series' Investment Adviser voluntarily waived a portion of their administration fee and management fee, respectively. Without such waivers, the Fund's performance would have been lower.

Significant Accounting Policies: Merrill Lynch S&P 500 Index Fund (the "Fund") is part of Merrill Lynch Index Funds, Inc. (the "Corporation"). The Fund is registered under the Investment Company Act of 1940, as amended, as a non-diversified mutual fund. The Fund's financial statements are prepared in conformity with accounting principles generally accepted in the United States of America, which may require the use of management accruals and estimates. These unaudited financial statements reflect all adjustments, which are, in the opinion of management, necessary to a fair statement of the results for the interim period presented. All such adjustments are of a normal, recurring nature. The Fund seeks to achieve its investment objective by investing all of its assets in Master S&P 500 Index Series (the "Series") of Quantitative Master Series Trust, which has the same investment objective as the Fund. The value of the Fund's investment in the Series reflects the Fund's proportionate interest in the net assets of the Series. The performance of the Fund is directly affected by the performance of the Series. The financial statements of the Series, including the Schedule of Investments, are included elsewhere in this report and should be read in conjunction with the Fund's financial statements. The percentage of the Series owned by the Fund at June 30, 2003 was 91.9%. The Fund offers multiple classes of shares. Effective April 14, 2003, Class A Shares were redesignated Class I Shares and Class D Shares were redesignated Class A Shares. The Fund's financial statements and financial highlights contained within this report reflect the new share class redesignation. Shares of Class A and Class I are sold without the imposition of a front-end or deferred sales charge. Both classes of shares have identical voting, dividend, liquidation and other rights and the same terms and conditions, except that Class A Shares bear certain expenses related to the account maintenance of such shares and have exclusive voting rights with respect to matters relating to their account maintenance expenditures. Income, expenses (other than expenses attributable to a specific class) and realized and unrealized gains and losses on investments are allocated daily to each class based on its relative net assets. The following is a summary of significant accounting policies followed by the Fund. (a) Valuation of investments -- The Fund records its investment in the Series at fair value. Valuation of securities held by the Series is discussed in Note 1a of the Series' Notes to Financial Statements, which are included elsewhere in this report. (b) Investment income and expenses -- The Fund records daily its proportionate share of the Fund's income, expenses and realized and unrealized gains and losses. In addition, the Fund accrues its own expenses. (c) Income taxes -- It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its taxable income to shareholders. Therefore, no Federal income tax provision is required. (d) Prepaid registration fees -- Prepaid registration fees are charged to expense as the related shares are issued. (e) Dividends and distributions -- Dividends and distributions paid by the Fund are recorded on the ex-dividend dates. (f) Investment transactions -- Investment transactions in the Series are accounted for on a trade date basis. 2. Transactions with Affiliates: The Corporation has entered into an Administrative Services Agreement with Merrill Lynch Investment Managers, L.P. ("MLIM"). The general partner of MLIM is Princeton Services, Inc. ("PSI"), a wholly-owned subsidiary of Merrill Lynch & Co., Inc. ("ML & Co.), which is the limited partner. The Fund pays a monthly fee at an annual rate of .245% of the Fund's average daily net assets for the performance of administrative services (other than investment advice and related portfolio activities) necessary for the operation of the Fund. The Corporation has also entered into a Distribution Agreement and Distribution Plan with FAM Distributors, Inc. ("FAMD" or the "Distributor"), which is a wholly-owned subsidiary of Merrill Lynch Group, Inc. Pursuant to the Distribution Plan adopted by the Corporation in accordance with Rule 12b-1 under the Investment Company Act of 1940, the Fund pays the Distributor an ongoing account maintenance fee. The fee is accrued daily and paid monthly at the annual rate of .25% based upon the average daily net assets of Class A shares. Pursuant to a sub-agreement with the Distributor, Merrill Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S"), a subsidiary of ML & Co., also provides account maintenance services to the Fund. The ongoing account maintenance fee compensates the Distributor and MLPF&S for providing account maintenance services to Class A shareholders. Financial Data Services, Inc. ("FDS"), an indirect, wholly-owned subsidiary of ML & Co., is the Fund's transfer agent. Certain officers and/or directors of the Fund are officers and/or directors of MLIM, PSI, FAMD, FDS, and/or ML & Co. 3.

See Notes to Financial Statements. NOTES TO FINANCIAL STATEMENTS MASTER S&P 500 INDEX SERIES 1. Significant Accounting Policies: Master S&P 500 Index Series (the "Series") is part of Quantitative Master Series Trust (the "Trust"). The Trust is registered under the Investment Company Act of 1940, as amended, and is organized as a Delaware statutory trust. The Declaration of Trust permits the Trustees to issue nontransferable interests in the Series, subject to certain limitations. The Series' financial statements are prepared in conformity with accounting principles generally accepted in the United States of America, which may require the use of management accruals and estimates. These unaudited financial statements reflect all adjustments, which are, in the opinion of management, necessary to a fair statement of the results for the interim period presented. All such adjustments are of a normal, recurring nature. The following is a summary of significant accounting policies followed by the Series. (a) Valuation of investments -- Portfolio securities that are traded on stock exchanges or the Nasdaq National Market are valued at the last sale price or official closing price on the exchange on which such securities are traded, as of the close of business on the day the securities are being valued or, lacking any sales, at the last available bid price for long positions, and at the last available ask price for short positions. Securities traded in the over-the-counter market are valued at the last available bid price prior to the time of valuation. In cases where securities are traded on more than one exchange, the securities are valued on the exchange designated by or under the authority of the Board of Trustees as the primary market. Securities that are traded both in the over-the-counter market and on a stock exchange are valued according to the broadest and most representative market. Options written or purchased are valued at the last sale price in the case of exchange-traded options. In the case of options traded in the over-the-counter market, valuation is the last asked price (options written) or the last bid price (options purchased). Short-term securities are valued at amortized cost, which approximates market value. Other investments, including futures contracts and related options, are stated at market value. Securities and assets for which market quotations are not available are valued at fair value as determined in good faith by or under the direction of the Trust's Board of Trustees. Occasionally, events affecting the values of securities and other assets may occur between the times at which valuations of such securities are determined (that is, close of the market on which such securities trade) and the close of business on the NYSE. If events (for example, company announcement, natural disasters, market volatility) occur during such periods that are expected to materially affect the value for such securities, those securities may be valued at their fair market value as determined in good faith by the Trust's Board of Trustees or by the investment adviser using a pricing service and/or procedures approved by the Board of Trustees of the Trust. (b) Derivative financial instruments -- The Series may engage in various portfolio investment strategies to provide liquidity or as a proxy for a direct investment in securities underlying the Series' index. Losses may arise due to changes in the value of the contract or if the counterparty does not perform under the contract. o Financial futures contracts -- The Series may purchase or sell financial futures contracts and options on such futures contracts. Upon entering into a contract, the Series deposits and maintains as collateral such initial margin as required by the exchange on which the transaction is effected. Pursuant to the contract, the Series agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in value of the contract. Such receipts or payments are known as variation margin and are recorded by the Series as unrealized gains or losses. When the contract is closed, the Series records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. o Options -- The Series is authorized to purchase and write call and put options. When the Series writes an option, an amount equal to the premium received by the Series is reflected as an asset and an equivalent liability. The amount of the liability is subsequently marked to market to reflect the current market value of the option written. When a security is purchased or sold through an exercise of an option, the related premium paid (or received) is added to (or deducted from) the basis of the security acquired or deducted from (or added to) the proceeds of the security sold. When an option expires (or the Series enters into a closing transaction), the Series realizes a gain or loss on the option to the extent of the premiums received or paid (or a gain or loss to the extent that the cost of the closing transaction exceeds the premium paid or received). Written and purchased options are non-income producing investments. (c) Foreign currency transactions -- Transactions denominated in foreign currencies are recorded at the exchange rate prevailing when recognized. Assets and liabilities denominated in foreign currencies are valued at the exchange rate at the end of the period. Foreign currency transactions are the result of settling (realized) or valuing (unrealized) assets or liabilities expressed in foreign currencies into U.S. dollars. Realized and unrealized gains or losses from investments include the effects of foreign exchange rates on investments. (d) Income taxes -- The Series is classified as a partnership for Federal income tax purposes. As such, each investor in the Series is treated as owner of its proportionate share of the net assets, income, expenses and realized and unrealized gains and losses of the Series. Therefore, no Federal income tax provision is required. Under the applicable foreign tax law, a withholding tax may be imposed on interest, dividends and capital gains at various rates. It is intended that the Series' assets will be managed so an investor in the Series can satisfy the requirements of subchapter M of the Internal Revenue Code. (e) Security transactions and investment income -- Security transactions are accounted for on the date the securities are purchased or sold (the trade dates). Realized gains and losses on security transactions are determined on the identified cost basis. Dividend income is recorded on the ex-dividend dates. Interest income is recognized on the accrual basis. (f) Securities lending -- The Series may lend securities to financial institutions that provide cash or securities issued or guaranteed by the U.S. government as collateral, which will be maintained at all times in an amount equal to at least 100% of the current market value of the loaned securities. 28 & 29 Merrill Lynch S&P 500 Index Fund, June 30, 2003 NOTES TO FINANCIAL STATEMENTS (concluded) MASTER S&P 500 INDEX SERIES The market value of the loaned securities is determined at the close of business of the Series and any additional required collateral is delivered to the Series on the next business day. Where the Series receives securities as collateral for the loaned securities, it collects a fee from the borrower. The Series typically receives the income on the loaned securities but does not receive the income on the collateral. Where the Series receives cash collateral, it may invest such collateral and retain the amount earned on such investment, net of any amount rebated to the borrower. Loans of securities are terminable at any time and the borrower, after notice, is required to return borrowed securities within five business days. The Series may pay reasonable finder's, lending agent, administrative and custodial fees in connection with its loans. In the event that the borrower defaults on its obligation to return borrowed securities because of insolvency or for any other reason, the Series could experience delays and costs in gaining access to the collateral. The Series also could suffer a loss where the value of the collateral falls below the market value of the borrowed securities, in the event of borrower default or in the event of losses on investments made with cash collateral. 2. Investment Advisory Agreement and Transactions with Affiliates: The Trust has entered into an Investment Advisory Agreement with Fund Asset Management, L.P. ("FAM"). The general partner of FAM is Princeton Services, Inc. ("PSI"), an indirect, wholly-owned subsidiary of Merrill Lynch & Co., Inc. ("ML & Co."), which is the limited partner. FAM is responsible for the management of the Series' portfolio and provides the necessary personnel, facilities, equipment and certain other services necessary to the operations of the Series. For such services, the Series pays a monthly fee at an annual rate of .005% of the average daily value of the Series' net assets. The Trust has received an exemptive order from the Securities and Exchange Commission permitting it to lend portfolio securities to Merrill Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S"), a subsidiary of ML & Co., or its affiliates. Pursuant to that order, the Trust also has retained Merrill Lynch Investment Managers, LLC ("MLIM, LLC"), an affiliate of FAM, as the securities lending agent for a fee based on a share of the returns on investment of cash collateral. MLIM, LLC may, on behalf of the Trust and the Series, invest cash collateral received by the Series for such loans, among other things, in a private investment company managed by MLIM, LLC or in registered money market funds advised by FAM or its affiliates. As of June 30, 2003, the Series lent securities with a value of $66,283,314 to MLPF&S or its affiliates. For the six months ended June 30, 2003, MLIM, LLC received $59,693 in securities lending agent fees from the Series. In addition, MLPF&S received $14 in commissions on the execution of portfolio security transactions for the Series for the six months ended June 30, 2003. Merrill Lynch Trust Company ("MLTC"), an indirect, wholly-owned subsidiary of ML & Co., is the Series' custodian. For the six months ended June 30, 2003, the Series reimbursed FAM $19,896 for certain accounting services. Certain officers and/or trustees of the Series are officers and/or directors of FAM, PSI, MLTC, and/or ML & Co. 3. Investments: Purchases and sales of investments, excluding short-term securities, for the six months ended June 30, 2003 were $200,960,407 and $19,288,012, respectively. Net realized gains (losses) for the six months ended June 30, 2003 and net unrealized losses as of June 30, 2003 were as follows: - -------------------------------------------------------------------------------- Realized Unrealized Gains (Losses) Losses - -------------------------------------------------------------------------------- Long-term investments ................ $ (13,023,861) $(113,462,470) Financial futures contracts .......... 2,438,163 (878,350) ------------- ------------- Total ................................ $ (10,585,698) $(114,340,820) ============= ============= - -------------------------------------------------------------------------------- As of June 30, 2003, net unrealized depreciation for Federal income tax purposes aggregated $188,893,236, of which $193,316,908 related to appreciated securities and $382,210,144 related to depreciated securities. At June 30, 2003, the aggregate cost of investments for Federal income tax purposes was $2,707,534,814. 4. Short-Term Borrowings: The Series, along with certain other funds managed by FAM and its affiliates, is a party to a $500,000,000 credit agreement with Bank One, N.A. and certain other lenders. The Series may borrow under the credit agreement to fund shareholder redemptions and for other lawful purposes other than for leverage. The Series may borrow up to the maximum amount allowable under the Series' current prospectus and statement of additional information, subject to various other legal, regulatory or contractual limits. The Series pays a commitment fee of ..09% per annum based on the Series pro rata share of the unused portion of the credit agreement. Amounts borrowed under the credit agreement bear interest at a rate equal to, at each fund's election, the Federal Funds rate plus .50% or a base rate as determined by Bank One, N.A. On November 29, 2002, the credit agreement was renewed for one year under the same terms, except that the commitment was reduced from $1,000,000,000 to $500,000,000. The Series did not borrow under the credit agreement during the six months ended June 30, 2003. 30 & 31 [LOGO] Merrill Lynch Investment Managers This report is not authorized for use as an offer of sale or a solicitation of an offer to buy shares of the Fund unless accompanied or preceded by the Fund's current prospectus.
