See Notes to Financial Statements. 12-M Master Mid Cap Index Series NOTES TO FINANCIAL STATEMENTS 1. Significant Accounting Policies: Master Mid Cap 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. 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. Series 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 Series employs pricing services to provide certain securities prices for the Series. 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 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 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 Board of Trustees or by the Investment Adviser using a pricing service and/or procedures approved by the Board of Trustees. 13-M (b) Derivative financial instruments - The Series may engage in various portfolio investment strategies both to increase the return of the Series and to hedge, or protect, its exposure to interest rate movements and movements in the securities markets. 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 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) 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. 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. (d) 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. (e) 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. 14-M 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 .01% of the Series' average daily net assets. The Series 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 Series 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 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, 2003, MLIM, LLC received $605 in securities lending agent fees. For the year ended December 31, 2003, the Series reimbursed FAM $1,253 or certain accounting services. Certain officers and/or trustees of the Trust are officers and/or directors of FAM, PSI, MLIM, LLC and/or ML & Co. 3. Investments: Purchases and sales of investments, excluding short-term securities, for the year ended December 31, 2003 were $27,008,013 and $5,003,969, respectively. Net realized gains (losses) for the year ended December 31, 2003 and net unrealized gains as of December 31, 2003 were as follows: ================================================================================ Realized Unrealized Gains (Losses) Gains - -------------------------------------------------------------------------------- Long-term investments ................... $ (48,317) $17,736,828 Financial futures contracts ............. 440,167 201,617 ----------- ----------- Total ................................... $ 391,850 $17,938,445 =========== =========== ================================================================================ As of December 31, 2003, net unrealized appreciation for Federal income tax purposes aggregated $16,650,396, of which $17,648,066 related to appreciated securities and $997,670 related to depreciated securities. At December 31, 2003, the aggregate cost of investments for Federal income tax purposes was $66,965,025. 4.

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 auditing standards generally accepted in the United States of America. 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 examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of December 31, 2003, by correspondence with the custodian. An audit also includes 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 the Master Mid-Cap Index Series of Quantitative Master Series Trust as of December 31, 2003, 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 respective periods then ended, in conformity with accounting principles generally accepted in the United States of America.

Item 3 - Audit Committee Financial Expert - The registrant's board of directors has determined that (i) the registrant has the following audit committee financial experts serving on its audit committee and (ii) each audit committee financial expert is independent: (1) Donald W. Burton, (2) M. Colyer Crum, (3) Laurie Simon Hodrick, (4) David H. Walsh and (5) Fred G. Weiss. The registrant's board of directors has determined that Laurie Simon Hodrick and M.

Ms. Hodrick has a thorough understanding of generally accepted accounting principals, financial statements, and internal controls and procedures for financial reporting. Ms. Hodrick earned a Ph.D. in economics and has taught courses in finance for over 15 years. Her M.B.A.-level course centers around the evaluation and analysis of firms' corporate financial statements. She has also taught in financial analysts' training programs. Ms. Hodrick has also worked with several prominent corporations in connection with the analysis of financial forecasts and projections and analysis of the financial statements of those companies, serving on the Financial Advisory Council of one of these major corporations.

For two such organizations, Professor Crum has performed extensive investment analysis of financial statements in connection with investment management decisions. From these experiences, he has gained significant experience with the establishment of reserves and accounting policies, differences between U.S. GAAP and Canadian GAAP and executive compensation issues. Item 4 - Principal Accountant Fees and Services (a) Audit Fees - 2003 -- $25,200 2002 -- $25,200 (b) Audit-Related Fees - 2003 -- $0 2002 -- $0 (c) Tax Fees - 2003 -- $8,800 2002 -- $10,500 The nature of the services include tax compliance, tax advice and tax planning. (d) All Other Fees - 2003 -- $0 2002 -- $0 (e)(1) The registrant's audit committee (the "Committee") has adopted policies and procedures with regard to the pre-approval of services. Audit, audit-related and tax compliance services provided to the registrant on an annual basis require specific pre-approval by the Committee. The Committee also must approve other non-audit services provided to the registrant and those non-audit services provided to the registrant's affiliated service providers that relate directly to the operations and the financial reporting of the registrant. Certain of these non-audit services that the Committee believes are a) consistent with the SEC's auditor independence rules and b) routine and recurring services that will not impair the independence of the independent accountants may be approved by the Committee without consideration on a specific case-by-case basis ("general pre-approval"). However, such services will only be deemed pre-approved provided that any individual project does not exceed $5,000 attributable to the registrant or $50,000 for the project as a whole. Any proposed services exceeding the pre-approved cost levels will require specific pre-approval by the Committee, as will any other services not subject to general pre-approval (e.g., unanticipated but permissible services). The Committee is informed of each service approved subject to general pre-approval at the next regularly scheduled in-person board meeting. (e)(2) 0% (f) N/A (g) 2003 -- $18,690,437 2002 -- $17,012,158 (h) The registrant's audit committee has considered that the provision of non-audit services that were rendered to the registrant's investment adviser and any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the registrant that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible with maintaining the principal accountant's independence.
