The U.S. stock market, as measured by the Standard & Poor's 500 Index, returned +6.27% for the six-month period and +22.88% for the 12-month period ended April 30, 2004. Though equity markets enjoyed favorable returns overall, we did experience an overdue market correction late in the period. This was largely in response to disappointing employment news (which has improved markedly since then), terrorist attacks in Madrid and instability in Iraq -- all of which weighed heavily on the markets. However, despite the more recent skittishness, we still observe substantial economic strength in the United States. In fact, the U.S. economy has continued to benefit from 2003's significant fiscal and monetary stimulus in the form of low interest rates and tax cuts. This has opened the door to consumer spending, capital spending, increases in exports and long-awaited job growth. A major shift on the employment front came on April 2 when the Department of Labor reported the biggest monthly jobs increase in four years. These developments have supported continued improvements in corporate earnings -- a positive for stock markets. For its part, the Federal Reserve Board maintained its accommodative policy stance, and is expected to raise interest rates at a gradual pace in order to ensure the sustainability of the current economic recovery. The events and efforts of the past year leave us with a much stronger economy today. Of course, markets will always fluctuate, and there are many uncertainties -- not the least of which are geopolitical in nature -- which can translate into negative market movements. Keeping this in mind, however, we encourage you to revisit your portfolio and your asset allocation strategy to ensure you are well positioned to take advantage of the opportunities that lie ahead. Importantly, your financial advisor can help you develop a strategy most suitable for your circumstances through all types of market and economic cycles. We thank you for trusting Merrill Lynch Investment Managers with your investment assets, and we look forward to serving you in the months and years ahead. Sincerely, /s/ Terry K. Glenn Terry K. Glenn President and Director/Trustee MERRILL LYNCH LARGE CAP GROWTH FUND APRIL 30, 2004 3 [LOGO] Merrill Lynch Investment Managers A Discussion With Your Fund's Portfolio Manager Despite a favorable backdrop of improving corporate earnings and economic revitalization, an equity market correction late in the period produced a drag on Fund performance. How did the Fund perform during the period in light of the existing market conditions? For the six-month period ended April 30, 2004, Merrill Lynch Large Cap Growth Fund's Class A, Class B, Class C, Class I and Class R Shares had total returns of +1.39%, +1.04%, +1.05%, +1.51% and +1.29%, respectively. (Fund results shown do not reflect sales charges and would be lower if sales charges were included. Complete performance information can be found on pages 6 and 7 of this report to shareholders.) While these returns reflect positive absolute results, the Fund's relative performance trailed the +4.14% return of the unmanaged benchmark, the Russell 1000 Growth Index, for the same period. In addition, the Fund underperformed its comparable Lipper category of Large-Cap Growth Funds, which posted a return of +2.42% for the same six-month period. (Funds in this Lipper category seek long-term growth of capital by investing in large-capitalization companies with long-term earnings expected to grow significantly faster than the earnings of the stocks represented in a major unmanaged stock index.) Importantly, over the long-term, the Fund has consistently outperformed its benchmark, the Russell 1000 Growth Index. Because the Fund invests in large-capitalization stocks that represent a significant part of the U.S. stock market, its portfolio was influenced by the same economic and market events that affected the broader stock market during the period. The last quarter of 2003 and the first quarter of 2004 were marked by dramatic rises and falls in world markets, with the equity markets undergoing a correction in the spring of 2004, despite strong economic growth and robust corporate earnings. What factors influenced Fund performance during the period? The Fund invests primarily in a diversified portfolio of large cap companies selected from securities found in the Russell 1000 Index. During the past six months, the Portfolio was positioned in economically sensitive cyclical stocks. Despite improving corporate earnings and economic revitalization, a combination of interest rate fears, rising energy prices, risks to growth in China and a destabilized U.S. dollar pushed equity prices lower late in the period. Given the Portfolio's heightened exposure to stocks leveraged to economic recovery and a market upturn, the correction had a greater impact on the Portfolio and ultimately resulted in the underperformance of the Fund relative to both its benchmark and its Lipper peers. Stock selection in the consumer discretionary and health care sectors benefited performance during the period. The Portfolio's overweight position in telecommunication services also contributed to performance. On the negative side, stock selection in information technology and consumer staples hindered results. At the individual stock level, the largest positive contributors to performance were Sprint Corp. (PCS), Genentech, Inc., DaVita, Inc., Motorola, Inc. and Waters Corporation. The largest detractors from performance included Amkor Technology, Inc., Foundry Networks, Inc., Emulex Corporation, SanDisk Corporation and ITT Educational Services, Inc.. Underweights in Exxon Mobil Corporation and The Gillette Company also negatively affected performance. What changes were made to the Portfolio during the period? We increased our positions relative to the benchmark in the materials, financials and consumer staples sectors based on our belief that stocks in these sectors would benefit as we transition from an economic recovery to an environment of rising interest rates. We reduced our position relative to the benchmark in information technology and telecommunication services in light of improved valuations and decelerating growth in these sectors. The largest purchases during the period included Cisco Systems, Inc., QUALCOMM Incorporated, Altria Group, Inc., Yahoo! Inc. and Texas Instruments Incorporated. The largest sales included Intel Corporation, Sprint Corp. (PCS), National Semiconductor Corporation, Staples, Inc. and American Tower Corporation. 4 MERRILL LYNCH LARGE CAP GROWTH FUND APRIL 30, 2004 How would you characterize the Portfolio's position at the close of the period? The Portfolio's largest overweights as of April 30, 2004 were in the consumer discretionary and information technology sectors, which we believe should benefit from strong earnings growth. The largest underweights were in financials, which tend to underperform in periods of rising interest rates, and telecommunication services. Companies exhibiting good earnings momentum, earnings surprise and valuation characteristics saw strong performance through the end of 2003. However, relative performance for these companies deteriorated as the broad markets turned downward in spring 2004. We remain committed to these disciplines for stock selection, and the Portfolio ended the period positioned in cyclical stocks that we believe should benefit as investor focus returns to the robust corporate earnings environment. Nonetheless, given the recent equity market correction and interest rate pressures, we are moderating our exposure to economic sensitivity as well as reducing our exposure to lower-capitalization securities. Our intention is to continue to reduce the interest rate sensitivity of the Portfolio as rates continue to increase. The Federal Funds futures market now projects a near certain hike in the Federal Funds target rate in June with another potential increase in August. We believe the economy is stronger than many expected at this point. Strong payroll reports for March and April, as well as recent data from the Institute for Supply Management survey, indicate that a sustainable economic recovery is underway, which should continue to support consumption and other business activity. We believe a modest increase in inflation also is underway, and our projection at the beginning of the year that the Federal Reserve Board would double its rate from 1% to 2% by year-end currently seems more realistic. The equity market correction, while not a surprise, has been more significant than expected, particularly given the boom in corporate earnings. Our view is that there is at least one more up-leg in the equity market before the cyclical backdrop becomes a problem. The timing of this rally will hinge on when the Treasury market calms, the dollar stabilizes or resumes its slow decline, and oil prices ease. Some combination of these factors should set the stage for more focus on earnings and a better equity market. In the meantime, sluggishness in stock prices is likely to persist. We will continue to monitor economic and market developments in order to make the most informed decisions regarding the Portfolio's investments. Robert C.

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 more current performance information. 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.

Significant Accounting Policies: Merrill Lynch Large Cap Growth Fund of Merrill Lynch Large Cap Series Funds, Inc. (the "Fund") is registered under the Investment Company Act of 1940, as amended, as a diversified mutual fund. The Fund seeks to achieve its investment objective by investing all of its assets in the Master Large Cap Growth Portfolio (the "Portfolio"), which is a portfolio of Master Large Cap Series Trust that has the same investment objective as the Fund. The value of the Fund's investment in the Portfolio reflects the Fund's proportionate interest in the net assets of the Portfolio. The performance of the Fund is directly affected by the performance of the Portfolio. The financial statements of the Portfolio, including the Schedule of Investments, are included elsewhere in this report and should be read in conjunction with the Fund's financial statements. 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. Actual results may differ from these 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 percentage of the Portfolio owned by the Fund at April 30, 2004 was 100%. The Fund offers multiple classes of shares. Shares of Class A and Class I are sold with a front-end sales charge. Shares of Class B and Class C may be subject to a contingent deferred sales charge. Class R Shares are sold only to certain retirement plans. All classes of shares have identical voting, dividend, liquidation and other rights and the same terms and conditions, except that Class A, Class B, Class C and Class R Shares bear certain expenses related to the account maintenance of such shares, and Class B, Class C and Class R Shares also bear certain expenses related to the distribution of such shares. Each class has exclusive voting rights with respect to matters relating to its account maintenance and distribution expenditures. Income, expenses (other than expenses attributable to a specific class) and realized and unrealized gains and losses on investments (and foreign currency transactions) 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 Portfolio at fair value. Valuation of securities held by the Portfolio is discussed in Note 1a of the Portfolio's 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 Portfolio'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. Under the applicable foreign tax law, a withholding tax may be imposed on interest, dividends and capital gains at various rates. (d) Prepaid registration fees -- Prepaid registration fees are charged to expenses 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 Portfolio are accounted for on a trade date basis. 2. Transactions with Affiliates: The Fund has entered into an Administration 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. The Fund pays a monthly fee at an annual rate of .25% 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 Fund has entered into a Distribution Agreement and Distribution Plans with FAM Distributors, Inc. ("FAMD" or the "Distributor"), which is a wholly-owned subsidiary of Merrill Lynch Group, Inc. Pursuant to the Distribution Plans adopted by the Fund in accordance with Rule 12b-1 under the Investment Company Act of 1940, the Fund pays the Distributor ongoing account maintenance and distribution fees. The fees are accrued daily and paid monthly at annual rates based upon the average daily net assets of the shares as follows: - -------------------------------------------------------------------------------- Account Distribution Maintenance Fee Fee - -------------------------------------------------------------------------------- Class A ............................. .25% -- Class B ............................. .25% .75% Class C ............................. .25% .75% Class R ............................. .25% .25% - -------------------------------------------------------------------------------- 16 MERRILL LYNCH LARGE CAP GROWTH FUND APRIL 30, 2004 Notes to Financial Statements (continued) Merrill Lynch Large Cap Growth 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 and distribution services to the Fund.

See Notes to Financial Statements. MERRILL LYNCH LARGE CAP GROWTH FUND APRIL 30, 2004 25 [LOGO] Merrill Lynch Investment Managers Notes to Financial Statements Master Large Cap Growth Portfolio 1. Significant Accounting Policies: Master Large Cap Growth Portfolio (the "Portfolio") is part of Master Large Cap Series Trust (the "Trust"). The Portfolio 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 Portfolio, subject to certain limitations. The Portfolio'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. Actual results may differ from these 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 Portfolio. (a) Valuation of investments -- Equity securities that are held by the Portfolio 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 Portfolio. 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 Portfolio. 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 Portfolio employs pricing services to provide certain securities prices for the Portfolio. 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 Portfolio, including valuations furnished by the pricing services retained by the Portfolio, which may use a matrix system for valuations. The procedures of a pricing service and its valuations are reviewed by the officers of the Portfolio under the general supervision of the Portfolio's Board of Trustees. Such valuations and procedures will be reviewed periodically by the Board of Trustees of the Portfolio. 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 Portfolio's shares 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 Portfolio's 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 Portfolio's Board of Trustees or by the Investment Adviser using a pricing service and/or procedures approved by the Portfolio's Board of Trustees. 26 MERRILL LYNCH LARGE CAP GROWTH FUND APRIL 30, 2004 Notes to Financial Statements (continued) Master Large Cap Growth Portfolio (b) Derivative financial instruments -- The Portfolio may engage in various portfolio investment strategies both to increase the return of the Portfolio 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 Portfolio 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 Portfolio deposits and maintains as collateral such initial margin as required by the exchange on which the transaction is effected. Pursuant to the contract, the Portfolio 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 Portfolio as unrealized gains or losses. When the contract is closed, the Portfolio 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 Portfolio may purchase and write call and put options. When the Portfolio writes an option, an amount equal to the premium received by the Portfolio 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 Portfolio enters into a closing transaction), the Portfolio 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. o Forward foreign exchange contracts -- The Portfolio may enter into forward foreign exchange contracts as a hedge against either specific transactions or portfolio positions. The contract is marked-to-market daily and the change in market value is recorded by the Portfolio as an unrealized gain or loss. When the contract is closed, the Portfolio records a realized gain or loss equal to the difference between the value at the time it was opened and the value at the time it was closed. o Foreign currency options and futures -- The Portfolio may also purchase or sell listed or over-the-counter foreign currency options, foreign currency futures and related options on foreign currency futures as a short or long hedge against possible variations in foreign exchange rates. Such transactions may be effected with respect to hedges on non-U.S. dollar denominated securities owned by the Portfolio, sold by the Portfolio but not yet delivered, or committed or anticipated to be purchased by the Portfolio. (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 Portfolio is considered as a "pass through" entity for Federal income tax purposes. As such, each investor in the Portfolio is treated as owner of its proportionate share of the net assets, income, expenses and realized and unrealized gains and losses of the Portfolio. 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 Portfolio's assets will be managed so an investor in the Portfolio can satisfy the requirements of subchapter M of the Internal Revenue Code. MERRILL LYNCH LARGE CAP GROWTH FUND APRIL 30, 2004 27 [LOGO] Merrill Lynch Investment Managers Notes to Financial Statements (continued) Master Large Cap Growth Portfolio (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. Dividends from foreign securities where the ex-dividend date may have passed are subsequently recorded when the Portfolio has determined the ex-dividend date. Interest income is recognized on the accrual basis. (f) Securities lending -- The Portfolio 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 Portfolio and any additional required collateral is delivered to the Portfolio on the next business day. Where the Portfolio receives securities as collateral for the loaned securities, it receives a fee from the borrower. The Portfolio typically receives the income on the loaned securities, but does not receive the income on the collateral. Where the Portfolio 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 Portfolio 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 Portfolio could experience delays and costs in gaining access to the collateral. The Portfolio 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 Portfolio's investments and provides the necessary personnel, facilities, equipment and certain other services necessary to the operations of the Portfolio. For such services, the Portfolio pays a monthly fee at an annual rate of .50% of the average daily value of the Portfolio's net assets. FAM has entered into a Sub-Advisory Agreement with Merrill Lynch Asset Management U.K., Limited ("MLAM U.K."), an affiliate of FAM, pursuant to which MLAM U.K. provides investment advisory services to FAM with respect to the Portfolio. There is no increase in the aggregate fees paid by the Portfolio for these services. The Portfolio 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 April 30, 2004, the Portfolio lent securities with a value of $3,448,255 to MLPF&S or its affiliates. Pursuant to that order, the Portfolio 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 Portfolio, invest cash collateral received by the Portfolio 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 April 30, 2004, MLIM, LLC received $5,748 in securities lending agent fees. 28 MERRILL LYNCH LARGE CAP GROWTH FUND APRIL 30, 2004 Notes to Financial Statements (concluded) Master Large Cap Growth Portfolio For the six months ended April 30, 2004, the Portfolio reimbursed FAM $2,711 for certain accounting services. Certain officers and/or trustees of the Trust are officers and/or directors of FAM, PSI, MLAM U.K. and/or ML & Co. 3. Investments: Purchases and sales of investments, excluding short-term securities, for the six months ended April 30, 2004 were $220,013,480 and $180,056,832, respectively. Net realized gains for the six months ended April 30, 2004 and net unrealized appreciation as of April 30, 2004 were as follows: - -------------------------------------------------------------------------------- Realized Unrealized Gains Appreciation - -------------------------------------------------------------------------------- Long-term investments ................ $16,932,671 $25,901,746 -------------------------------- Total ................................ $16,932,671 $25,901,746 ================================ As of April 30, 2004, net unrealized appreciation for Federal income tax purposes aggregated $21,355,227, of which $36,045,942 related to appreciated securities and $14,690,715 related to depreciated securities. At April 30, 2004, the aggregate cost of investments for Federal income tax purposes was $311,178,123. 4. Short-Term Borrowings: The Portfolio, along with certain other funds managed by FAM and its affiliates, is party to a $500,000,000 credit agreement with Bank One, N.A. and certain other lenders. The Portfolio may borrow under the credit agreement to fund investor withdrawals and for other lawful purposes other than for leverage. The Portfolio may borrow up to the maximum amount allowable under the Portfolio's current prospectus and statement of additional information, subject to various other legal, regulatory or contractual limits. The Portfolio pays a commitment fee of .09% per annum based on the Portfolio's pro rata share of the unused portion of the facility. Amounts borrowed under the facility 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 28, 2003, the credit agreement was renewed for one year under the same terms. The Portfolio did not borrow under the facility during the six months ended April 30, 2004.
