Contributors and Detractors from Performance: The portfolio met its objective of closely tracking the return of its benchmark. After a negative 1st quarter, the 2nd quarter of 2003 brought impressive gains and what some are calling a "bull rally." The US markets rose consistently over the quarter, spurred by optimism that economic and profit growth will accelerate. On June 16th the S&P 500 closed above the 1,000 mark (at 1,010.74) for the first time since June 20, 2002. Most indices finished the quarter in positive territory, with the DJIA closing at 8,985.44, up 993.31 points or 12.43% for the quarter, and the S&P 500 closing at 974.50, 126.32 points or 14.89% for the quarter. The NASDAQ closed at 1,622.80, up 281.63 points or 21.00%, as technology stocks have outperformed the broader market on expectations that companies in that sector will be among the first beneficiaries of an economic recovery. Performance Analysis: Value outperformed growth for the quarter, with the S&P 400 Barra Value Index posting a return of 19.18% versus the S&P 400 Barra Growth Index returning 16.01%. This trend was also seen among large caps, as the S&P 500 Barra Value Index returned 18.84% while the S&P 500 Barra Growth Index returned 12.17%. Turning to sector performance, all S&P 400 sectors posted positive returns for the quarter. The top performer was Telecommunications Services, up 29.52%, followed by Information Technology and Consumer Discretionary, with respective returns of 25.86% and 22.23%. Worst performers for the quarter were Energy, Materials and Industrials with respective returns of 7.28%, 11.08%, and 13.42%. Markets rallied following the resolution of military affairs in Iraq, investors have become increasingly bullish about the outlook for equities, and the rise has been notable for the participation of 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. After the Federal Open Market Committee (FOMC) left rates unchanged at 1.25% at its May 6th meeting, it lowered its target for the federal funds rate by 25 basis points to 1% at its June 25th meeting, bringing the rate to a 49-year low. The FOMC 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 rate reductions in the future. In response to the Feds 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. Fund Position Going Forward: 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 geo-political 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 clearly 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 of 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 last 6 months of 2003, putting the economy on a recovery track. With that in mind, the portfolio is expected to continue to meets its objectives. /s/ Richard Vella - ----------------- Richard Vella Vice President and Portfolio Manager /s/ Terry K.

See Notes to Financial Statements. 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. 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 financial futures contracts and related options, are stated at market value. Securities and assets for which market value quotations are not readily available are valued at their 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) 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. 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 six months ended June 30, 2003, MLIM, LLC received $301 in securities lending agent fees. For the six months ended June 30, 2003, the Series reimbursed FAM $511 for certain accounting services.
