Fixed income markets also performed well, with high yield bond investors enjoying some of the greatest returns. Over the past year, the equity market generally found support from a healthy economic environment, above-average corporate earnings, increased capital spending and still-low interest rates. Stalling the momentum somewhat throughout the year was a contentious election, negligible inflation amid a rising federal funds interest rate, record-high oil prices and the seemingly ever-present worries over terrorism and the war in Iraq. Still, the Standard & Poor's 500 Index posted a 12-month return of +10.88% and a six-month return of +7.19% as of December 31, 2004. The fourth quarter of the year proved to be the most telling, as the S&P 500 Index was up only 1.51% year-to-date as of September 30, 2004. As the price of oil relaxed and election uncertainties subsided, the market headed more convincingly upward in the last quarter of the year. Given the relatively positive environment for equities, the favorable performance of the bond market came as somewhat of a surprise. The Lehman Brothers Aggregate Bond Index posted a 12-month return of +4.34% and a six-month return of +4.18% as of December 31, 2004. The tax-exempt market performed just as well, with a 12-month return of +4.48% and a six-month return of +5.19%, as measured by the Lehman Brothers Municipal Bond Index. Those comfortable with a higher degree of risk benefited this past year, as the Credit Suisse First Boston High Yield Index posted a 12-month return of +11.95% and a six-month return of +9.26%. Interestingly, as the Federal Reserve Board began raising its target short-term interest rate, long-term bond yields were little changed. In fact, the yield on the 10-year Treasury was 4.24% at year-end compared to 4.27% at December 31, 2003. The yield on the two-year Treasury climbed to 3.08% at year-end 2004 from 1.84% a year earlier. As always, our investment professionals are closely monitoring the markets, the economy and the overall environment in an effort to make well-informed decisions for the portfolios they manage. For the individual investor, the key to investment success -- particularly during uncertain times -- is to maintain a long-term perspective and adhere to the disciplines of asset allocation, diversification and rebalancing. We encourage you to work with your financial advisor to ensure these time-tested techniques are incorporated into your investment plan. We thank you for trusting Merrill Lynch Investment Managers with your investment assets, and we look forward to serving you in the new year and beyond. Sincerely, /s/ Robert C. Doll, Jr. Robert C. Doll, Jr. President and Chief Investment Officer Merrill Lynch Investment Managers MERRILL LYNCH S&P 500 INDEX FUND DECEMBER 31, 2004 3 [LOGO] Merrill Lynch Investment Managers A Discussion With Your Fund's Portfolio Managers The Fund was able to meet its objective of closely replicating the returns of the S&P 500 Index during the year, and provided a double-digit total return. How did the Fund perform during the fiscal year? For the 12-month period ended December 31, 2004, Merrill Lynch S&P 500 Index Fund's Class A and Class I Shares had total returns of +10.22% and +10.55%, respectively. For the same period, the Fund's benchmark, the Standard & Poor's 500 (S&P 500) Index, returned +10.88%. (Complete performance information can be found on pages 6 and 7 of this report to shareholders.) As the returns indicate, the Fund met its objective of closely tracking the performance of the S&P 500 Index, a market-weighted index composed of 500 common stocks issued by large-capitalization U.S. companies in a wide range of businesses. The stocks included in the Index collectively represent a substantial portion of all common stocks publicly traded in the United States. As the value of the S&P 500 Index fluctuated during the past 12 months, the Fund's performance generally tracked that of the Index. Throughout the period, as changes were made to the composition of the S&P 500 Index, we purchased and sold securities to maintain the Fund's objective of replicating the risks and return of the benchmark. As an index fund, the portfolio mirrors the composition of the S&P 500 Index, a common measure of U.S. market performance for large cap stocks. What developments affected the market for large cap stocks during the period? The S&P 500 Index finished 2004 on a positive note, although it was not a straight march upward. Index gains were modest in the first and second quarters of the year, at +1.69% and +1.72%, respectively. The S&P 500 Index slid in the third quarter, returning -1.87%, but experienced a strong bounce back in the fourth quarter, with a return of +9.23%. Economic news was mixed for much of the first three quarters before turning generally positive in the fourth quarter. The first quarter was impacted positively by good productivity and gross domestic product numbers, but clouded by the railroad bombing in Madrid, Spain, which caused market volatility to increase substantially. Renewed fears of terrorist attacks cast the long shadow of geopolitical unrest on equity markets around the world. The aura of uncertainty in the second quarter was led by factors such as persistent violence in Iraq, record-high oil prices and mixed, though slowly improving, U.S. economic data. As the second quarter drew to a close, the drumbeat of presidential election drama gradually swelled in the United States. In the third quarter, the course of economic news slowly began to point toward a strengthening economy. But despite better-than-expected corporate earnings and the Federal Reserve Board (the Fed) Chairman Alan Greenspan's congressional testimony that his outlook on economic growth remained constructive, a number of uncertainties hampered the U.S. equity market. Election buildup, a shifting Fed policy and higher oil prices fanned the flames of fear that the U.S. economy would slow. The fourth quarter, however, proved to be the breakout that investors were looking for in the U.S. equity markets. Negative October headlines segued into positive November and December news. As a result of moderating oil prices, unwinding election uncertainties, reasonably good economic and earnings news, and the beginning of the seasonally strong year-end period, the market experienced a positive post-election bounce. As expected, the Fed continued to raise the federal funds interest rate, which ended the year at 2.25%, more than double where it started. On December 31, 2004, the S&P 500 Index closed at 1,211.92 with a price return of +8.99%. The Dow Jones Industrial Average closed at 10,783.01 with a price return of +3.15%, while the Nasdaq Composite Index returned +8.59% with a closing level of 2,175.44. European markets delivered comparable gains, with the Financial Times Stock Exchange 100 Index closing at 4,814.30, representing a return of +7.54% in sterling. In the meantime, the Morgan Stanley Capital International World Index was up 12.84% in U.S. dollar terms, with a closing level of 1,169.34 at December 31, 2004. 4 MERRILL LYNCH S&P 500 INDEX FUND DECEMBER 31, 2004 Value-style investing outperformed the growth style for the year, as the S&P 500 Barra Value Index returned +15.70% versus the +6.13% return of the S&P 500 Barra Growth Index. Small- and mid-capitalization stocks generally had better returns than large-capitalization stocks in 2004, with the S&P SmallCap 600 Index returning +22.65% and the S&P MidCap 400 Index returning +16.48%. Turning to sector performance, all 10 S&P 500 sectors posted positive returns for the year. The top performer was energy, which was up 28.77%, followed by utilities and telecommunication services, with respective returns of +19.60% and +15.98%. The worst performer for the year was health care, which was up only ..24%. Also at the bottom were information technology and consumer staples, with respective one-year returns of +2.13% and +6.04%. How would you characterize market conditions at the close of the period? As 2004 came to an end, the economy and earnings growth were beginning to slow, the Fed appeared poised to continue moving interest rates higher, legislative progress was anticipated on many fronts in Washington, DC, and concerns remained about the structural problems of debt and deficits as reflected by a significant decline in the U.S. dollar. The recent increase in equity prices to new cyclical highs has led to questions about how much upside potential exists. Valuation levels, at least on an absolute basis, are somewhat stretched, although the profit environment is still strong enough to support the market. Equity prices could have fallen as a result of the Fed's recent interest rate hike, but clearly have been benefiting from recent declines in bond yields as well as from the declining dollar. Our opinion is that until monetary tightening and/or rising bond yields begin to take their toll, equities should continue to perform well. Having said that, we expect the portfolio to continue to meet its objective of tracking the performance of the S&P 500 Index. Vincent J. Costa Co-Portfolio Manager Debra L.

In addition, Class A Shares are subject to an ongoing account maintenance fee of .25% per year. o Class I Shares do not incur an 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. Current performance may be lower or higher than the performance data quoted. Refer to www.mlim.ml.com to obtain performance data current to the most recent month-end. 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 gain distributions, if any, 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 following example (which is based on a hypothetical investment of $1,000 invested on July 1, 2004 and held through December 31, 2004) is intended to assist shareholders both in calculating expenses based on an investment in the Fund and in comparing these expenses with similar costs of investing in other mutual funds. The first table below provides information about actual account values and actual expenses. In order to estimate the expenses a shareholder paid during the period covered by this report, shareholders can divide their account value by $1,000 and then multiply the result by the number in the first line under the heading entitled "Expenses Paid During the Period." The second table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses. In order to assist shareholders in comparing the ongoing expenses of investing in this Fund and other funds, compare the 5% hypothetical example with the 5% hypothetical examples that appear in other funds' shareholder reports. The expenses shown in the table are intended to highlight shareholders ongoing costs only and do not reflect any transactional expenses, such as sales charges, redemption fees or exchange fees. Therefore, the second table is useful in comparing ongoing expenses only, and will not help shareholders determine the relative total expenses of owning different funds. If these transactional expenses were included, shareholder expenses would have been higher.

Because the Fund is a feeder fund, the expense table example reflects the expenses of both the feeder fund and the master series in which it invests. ** Hypothetical 5% annual return before expenses is calculated by pro-rating the number of days in the most recent fiscal half year divided by 366. 8 MERRILL LYNCH S&P 500 INDEX FUND DECEMBER 31, 2004 Statement of Assets and Liabilities Merrill Lynch S&P 500 Index Fund As of December 31, 2004 ============================================================================================================================ Assets - ---------------------------------------------------------------------------------------------------------------------------- Investment in Master S&P 500 Index Series (the "Series"), at value (identified cost--$2,193,021,062) .................. $ 2,594,788,227 Prepaid expenses ............................................. 22,997 --------------- Total assets ................................................. 2,594,811,224 --------------- ============================================================================================================================ Liabilities - ---------------------------------------------------------------------------------------------------------------------------- Payables: Administrative fees ....................................... $ 601,664 Distributor ............................................... 196,658 798,322 --------------- Accrued expenses and other liabilities ....................... 981,311 --------------- Total liabilities ............................................ 1,779,633 --------------- ============================================================================================================================ Net Assets - ---------------------------------------------------------------------------------------------------------------------------- Net assets ................................................... $ 2,593,031,591 =============== ============================================================================================================================ Net Assets Consist of - ---------------------------------------------------------------------------------------------------------------------------- Class A Shares of Common Stock, $.0001 par value, 250,000,000 shares authorized ............................... $ 6,344 Class I Shares of Common Stock, $.0001 par value, 250,000,000 shares authorized ............................... 11,140 Paid-in capital in excess of par ............................. 2,395,780,378 Undistributed investment income--net ......................... $ 728,636 Accumulated realized capital losses allocated from the Series--net .................................................

See Notes to Financial Statements. MERRILL LYNCH S&P 500 INDEX FUND DECEMBER 31, 2004 13 [LOGO] Merrill Lynch Investment Managers Notes to Financial Statements Merrill Lynch S&P 500 Index Fund 1. 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 U.S. generally accepted accounting principles, which may require the use of management accruals and estimates. Actual results may differ from these estimates. 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 and strategies 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 December 31, 2004 was 88.3%. The Fund offers multiple classes of shares. 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 Series' 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"), an indirect, 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. MLIM has entered into a voluntary arrangement with the Fund under which the expenses incurred by each class of shares of the Fund (excluding account maintenance fees) will not exceed .40%. This arrangement has a one-year term and is renewable. The Corporation has also entered into a Distribution Agreement and Distribution Plan with FAM Distributors, Inc. ("FAMD" or the "Distributor"), which is an indirect, 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. 14 MERRILL LYNCH S&P 500 INDEX FUND DECEMBER 31, 2004 Notes to Financial Statements (concluded) Merrill Lynch S&P 500 Index Fund 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"), a 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. Capital Share Transactions: Net increase in net assets derived from capital share transactions was $77,228,211 and $258,203,138 for the years ended December 31, 2004 and December 31, 2003, respectively.

Distributions to Shareholders: The tax character of distributions paid during the fiscal years ended December 31, 2004 and December 31, 2003 was as follows: - -------------------------------------------------------------------------------- 12/31/2004 12/31/2003 - -------------------------------------------------------------------------------- Distributions paid from: Ordinary income ............................ $38,365,080 $26,174,395 --------------------------- Total taxable distributions ..................... $38,365,080 $26,174,395 =========================== As of December 31, 2004, the components of accumulated earnings on a tax basis were as follows: - ----------------------------------------------------------------------------- Undistributed ordinary income -- net .................... $ 728,636 Undistributed long-term capital gains -- net ............ -- ------------- Total undistributed earnings -- net ..................... 728,636 Capital loss carryforward ...............................

This amount will be available to offset like amounts of any future taxable gains. ** The difference between book-basis and tax-basis net unrealized gains is attributable primarily to the tax deferral of losses on wash sales and the realization for tax purposes of unrealized gains on certain futures contracts. MERRILL LYNCH S&P 500 INDEX FUND DECEMBER 31, 2004 15 [LOGO] Merrill Lynch Investment Managers Report of Independent Registered Public Accounting Firm Merrill Lynch S&P 500 Index Fund To the Shareholders and Board of Directors of Merrill Lynch Index Funds, Inc.: We have audited the accompanying statement of assets and liabilities of Merrill Lynch S&P 500 Index Fund, one of the series constituting Merrill Lynch Index Funds, Inc. (the "Fund"), as of December 31, 2004, 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, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, 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. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Merrill Lynch S&P 500 Index Fund of Merrill Lynch Index Funds, Inc. as of December 31, 2004, 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.

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 U.S. generally accepted accounting principles, which may require the use of management accruals and estimates. Actual results may differ from these estimates. The following is a summary of significant accounting policies followed by the Series. (a) Valuation of investments -- Equity securities that are held by the Series that are traded on stock exchanges or the Nasdaq National Market are valued at the last sale price or official close price on the exchange, 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. In cases where equity securities are traded on more than one exchange, the securities are valued on the exchange designated as the primary market by or under the authority of the Board of Trustees of the Trust. Long positions traded in the over-the-counter ("OTC") market, Nasdaq Small Cap or Bulletin Board are valued at the last available bid price or yield equivalent obtained from one or more dealers or pricing services approved by the Board of Trustees of the Trust. Short positions traded in the OTC market are valued at the last available ask price. Portfolio securities that are traded both in the OTC market and on a stock exchange are valued according to the broadest and most representative market. Options written are valued at the last sale price in the case of exchange-traded options or, in the case of options traded in the OTC market, the last ask price. Options purchased are valued at their last sale price in the case of exchange-traded options or, in the case of options traded in the OTC market, the last bid price. Swap agreements are valued daily based upon quotations from market makers. Financial futures contracts and options thereon, which are traded on exchanges, are valued at their last sale price as of the close of such exchanges. Obligations with remaining maturities of 60 days or less are valued at amortized cost unless the Investment Adviser believes that this method no longer produces fair valuations. Repurchase agreements are valued at cost plus accrued interest. The Trust employs pricing services to provide certain securities prices for the Trust. Securities and assets for which market quotations are not readily available are valued at fair value as determined in good faith by or under the direction of the Board of Trustees of the Trust, including valuations furnished by the pricing services retained by the Trust, which may use a matrix system for valuations. The procedures of a pricing service and its valuations are reviewed by the officers of the Trust under the general supervision of the Trust's Board of Trustees. Such valuations and procedures will be reviewed periodically by the Board of Trustees of the Trust. Generally, trading in foreign securities, as well as U.S. government securities and money market instruments, is substantially completed each day at various times prior to the close of business on the New York Stock Exchange ("NYSE"). The values of such securities used in computing the net assets of the Series are determined as of such times. Foreign currency exchange rates also are generally determined prior to the close of business on the NYSE. Occasionally, events affecting the values of such securities and such exchange rates may occur between the times at which they are determined and the close of business on the NYSE that may not be reflected in the computation of the Series' net assets. If events (for example, a company announcement, market volatility or a natural disaster) occur during such periods that are expected to materially affect the value of such securities, those securities may be valued at their fair 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 Trust's Board of Trustees. (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. MERRILL LYNCH S&P 500 INDEX FUND DECEMBER 31, 2004 25 [LOGO] Merrill Lynch Investment Managers Notes to Financial Statements (continued) Master S&P 500 Index Series o Financial futures contracts -- The Series may purchase or sell financial futures contracts and options on such futures contracts. Futures contracts are contracts for delayed delivery of securities at a specific future date and at a specific price or yield. 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 may 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. 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. 26 MERRILL LYNCH S&P 500 INDEX FUND DECEMBER 31, 2004 Notes to Financial Statements (concluded) Master S&P 500 Index Series (g) Custodian bank -- The Fund recorded an amount payable to the custodian bank reflecting an overnight overdraft, which resulted from management estimates of available cash. 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 of FAM. 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. As of December 31, 2004, the Series lent securities with a value of $24,987,449 to MLPF&S 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. For the year ended December 31, 2004, MLIM, LLC received $103,892 in securities lending agent fees from the Series. Merrill Lynch Trust Company ("MLTC"), a wholly-owned subsidiary of ML & Co., is the Series' custodian. For the year ended December 31, 2004, the Series reimbursed FAM $52,238 for certain accounting services. Certain officers and/or trustees of the Trust 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 year ended December 31, 2004 were $439,815,033 and $154,386,107, respectively. 4. Short-Term Borrowings: The Trust, on behalf of the Series, along with certain other funds managed by FAM and its affiliates, is a party to a $500,000,000 credit agreement with a group of 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 .07% 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 Series' election, the federal funds rate plus .50% or a base rate as defined in the credit agreement. The Series did not borrow under the credit agreement during the year ended December 31, 2004. On November 26, 2004, the credit agreement was renewed for one year under substantially the same terms. MERRILL LYNCH S&P 500 INDEX FUND DECEMBER 31, 2004 27 [LOGO] Merrill Lynch Investment Managers Report of Independent Registered Public Accounting Firm Master S&P 500 Index Series To the Investors and Board of Trustees of Quantitative Master Series Trust: We have audited the accompanying statement of assets and liabilities, including the summary schedule of investments, of Master S&P 500 Index Series, one of the portfolios constituting the Quantitative Master Series Trust (the "Trust"), as of December 31, 2004, 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, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Trust's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, 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. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2004, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Master S&P 500 Index Series of the Quantitative Master Series Trust as of December 31, 2004, 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.
