Annual Report October 31, 2003 [LOGO] Merrill Lynch Investment Managers A Letter From the President [PHOTO OMITTED] Dear Shareholder As 2003 draws to a close, it seems appropriate to reflect on what has been a meaningful year in many respects. We saw the beginning and the end of all-out war in Iraq, equity market uncertainty turned to strength and sub par gross domestic product (GDP) growth of 1.4% in the first quarter of 2003 grew to an extraordinary 8.2% in the third quarter. Equity markets rebounded from one of the most dismal three-year periods in history to make a strong showing this year. The S&P 500 Index posted year-to-date and 12-month returns of +21.21% and +20.80%, respectively, as of October 31, 2003. The Russell 1000 Index returned +22.49% year-to-date and +22.32% over the past 12 months. Although continued market strength cannot be assured, the positives have begun to eclipse the negatives. In addition to the impressive GDP growth, the positive economic news includes waning risk of deflation and surprisingly strong business spending and corporate earnings. In fact, business spending in the third quarter was the strongest it has been in three years, up 14%, and many company earnings reports exceeded forecasts in the first three quarters of the year. At Merrill Lynch Investment Managers, we believe the recent optimism suggests it is time for investors to consider "what can go right." The long market downturn may have taken a toll on your investment portfolio. We encourage you to review your portfolio and your asset allocation strategy to ensure you are positioned to take advantage of potential investment opportunities. We thank you for trusting Merrill Lynch Investment Managers with your investment assets, and we look forward to serving your financial needs in the months and years ahead. Sincerely, /S/ Terry K.

How did the Fund perform during the period in light of the existing market conditions? For the 12-month period ended October 31, 2003, the Fund's Class A, Class B, Class C and Class I Shares had total returns of +24.00%, +23.05%, +23.05% and +24.31%, 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 - 9 of this report to shareholders.) These results compare quite favorably to the +22.32% return of the Fund's unmanaged benchmark, the Russell 1000 Index, for the same period. In addition, the Fund significantly outperformed its comparable Lipper category of Large-Cap Core Funds, which posted an average return of +17.75% for the same 12-month period. For the six months ended October 31, 2003, the Fund's Class A, Class B, Class C and Class I Shares had total returns of +23.10%, +22.74%, +22.74% and +23.42%, respectively. The six-month results were well ahead of the +16.77% total return of the Russell 1000 Index and the +14.42% average return of the Lipper Large-Cap Core Funds for the same period. The Fund invests primarily in a diversified portfolio (Master Large Cap Core Portfolio) of large cap companies selected from securities found in the Russell 1000 Index. During this particular period, the main driver of the positive performance was stock selection in the consumer discretionary and health care sectors. In contrast, stock selection in information technology had a negative impact on Fund returns. In the last six months of the fiscal year, the Portfolio began to benefit from its exposure to cyclical stocks -- those believed to strengthen along with a strengthening economy. This enabled the Fund to gain significant ground relative to both its benchmark and its peers. Stock selection in the health care and consumer discretionary sectors benefited performance in the last six months. The Portfolio's overweight in information technology also contributed to performance. On the negative side, stock selection in utilities was a drag on performance. At the individual stock level, the largest positive contributors to performance in the last six months were Invitrogen Corporation, Humana Inc., Ryland Group Inc., SanDisk Corporation, National Semiconductor Corporation and Juniper Networks, Inc. The largest detractors from performance included Calpine Corporation and Dynegy, Inc. Underweights in Altria Group, Inc. and Intel Corporation also negatively impacted performance. 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 2002 and the first quarter of 2003 were marked by dramatic rises and falls in world markets, sub par economic growth and frail consumer confidence. This was prompted by geopolitical uncertainties, particularly war fears, and exacerbated by a weak employment picture. The period following the Iraq war, however, saw a rise in investor confidence that drove the major stock market indexes to levels not seen since early in 2002. Despite alternating periods of rising and falling consumer confidence, spending by consumers helped propel the slow and steady growth of the economy throughout the entire period. Capital spending by businesses remained sluggish until late in the period when signs of a pickup began to emerge, along with improved corporate earnings and a third-quarter 2003 jump in gross domestic product. What changes were made to the Portfolio during the fiscal year? We increased our position relative to the benchmark in technology based on our belief that stocks in this sector would benefit from the increases in business and consumer spending that accompany economic recovery. We reduced our position relative to the benchmark in financials in light of the potential for rising interest rates over the next 12 months, as the financial sector tends to lag in periods of rising rates. We also reduced our position in consumer staples, as these stocks tend to be more defensive in nature. Accordingly, we would not expect the sector to benefit meaningfully during times of economic recovery. The largest purchases during the period included The Bear Stearns Companies, Inc., Calpine, Citigroup Inc. and Sprint Corp. (PCS Group). The largest sales included Bank of America Corporation, H&R Block, Inc., CheckFree Corp. and National City Corporation. 4 MERRILL LYNCH LARGE CAP CORE FUND OCTOBER 31, 2003 How would you characterize the Portfolio's position at the close of the period? The Portfolio's largest overweights as of October 31, 2003 were in information technology and consumer discretionary, which we believe should continue to benefit from economic improvement. The largest underweights were in consumer staples and financials. Companies exhibiting good earnings momentum, earnings surprise and valuation characteristics saw a pickup in performance late in the summer that accelerated in the fall. We remain committed to these disciplines for stock selection, although cognizant that the equity market could experience a temporary downturn at any time. Looking ahead, we believe the economic recovery will continue to gain traction. Record monetary and fiscal policy stimulus, in the form of low interest rates and tax cuts, along with solid consumer spending and increasing business spending, all support this thesis. The job market was still disappointingly weak as we ended the period, but there were signs of improvement. As low interest rates continue to make for a positive liquidity environment, we are reluctant to abandon our strategy of focusing on cyclical stocks that have the potential to benefit from economic recovery. We are prepared to move to a more cautious investment stance as the likelihood of monetary tightening by the Federal Reserve Board approaches, although that still seems months away. From a longer-term perspective, the U.S. current account imbalance and the potential for a destabilizing decline in the dollar pose the greatest threats to our outlook. We will continue to monitor these situations for developments that could potentially impact the Fund. Robert C. Doll, Jr. Senior Vice President and Senior Portfolio Manager November 26, 2003 MERRILL LYNCH LARGE CAP CORE FUND OCTOBER 31, 2003 5 [LOGO] Merrill Lynch Investment Managers Performance Data About Fund Performance Effective April 14, 2003, Class A Shares were redesignated Class I Shares and Class D Shares were redesignated Class A Shares. Investors are able to purchase shares of the Fund through multiple pricing alternatives: o Class A Shares incur a maximum initial sales charge of 5.25% and an account maintenance fee of 0.25% (but no distribution fee). o Class B Shares are subject to a maximum contingent deferred sales charge of 4% declining to 0% after six years. All Class B Shares purchased prior to June 1, 2001 will maintain the four-year schedule. In addition, Class B Shares are subject to a distribution fee of 0.75% and an account maintenance fee of 0.25%. These shares automatically convert to Class A Shares after approximately eight years. (There is no initial sales charge for automatic share conversions.) o Class C Shares are subject to a distribution fee of 0.75% and an account maintenance fee of 0.25%. In addition, Class C Shares are subject to a 1% contingent deferred sales charge if redeemed within one year of purchase. o Class I Shares incur a maximum initial sales charge (front-end load) of 5.25% and bear no ongoing distribution or account maintenance fees. Class I Shares are available only to eligible investors. o Class R Shares do not incur a maximum sales charge (front-end load) or deferred sales charge. These shares are subject to a distribution fee of 0.25% and an account maintenance fee of 0.25%. Class R Shares are available only to certain retirement plans. None of the past results shown should be considered a representation of future performance. Performance results do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. Figures shown in each of the following tables assume reinvestment of all dividends and capital gains distributions at net asset value on the ex-dividend date. Investment return and principal value of shares will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. Dividends paid to each class of shares will vary because of the different levels of account maintenance, distribution and transfer agency fees applicable to each class, which are deducted from the income available to be paid to shareholders. 6-Month 12-Month Since Inception As of October 31, 2003 Total Return Total Return Total Return ============================================================================================================= ML Large Cap Core Fund Class A Shares* +23.10% +24.00% + 2.33% - ------------------------------------------------------------------------------------------------------------- ML Large Cap Core Fund Class B Shares* +22.74 +23.05 - 0.69 - ------------------------------------------------------------------------------------------------------------- ML Large Cap Core Fund Class C Shares* +22.74 +23.05 - 0.69 - ------------------------------------------------------------------------------------------------------------- ML Large Cap Core Fund Class I Shares* +23.42 +24.31 + 3.35 - ------------------------------------------------------------------------------------------------------------- ML Large Cap Core Fund Class R Shares* +23.25 -- +23.40 - ------------------------------------------------------------------------------------------------------------- Russell 1000 Index** +16.77 +22.32 -20.81/+18.66 - ------------------------------------------------------------------------------------------------------------- * Investment results shown do not reflect sales charges; results shown would be lower if a sales charge was included.

See Notes to Financial Statements. MERRILL LYNCH LARGE CAP CORE FUND OCTOBER 31, 2003 17 [LOGO] Merrill Lynch Investment Managers Notes to Financial Statements Merrill Lynch Large Cap Core Fund 1. Significant Accounting Policies: Merrill Lynch Large Cap Core 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 Core 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. The percentage of the Portfolio owned by the Fund at October 31, 2003 was 85.4%. The Fund offers multiple classes of shares. Effective April 14, 2003, Class A Shares were redesignated Class I Shares and Class D Shares were redesignated Class A Shares. The Fund's financial statements and financial highlights contained within this report reflect the new share class redesignation. Shares of Class A and Class I are sold 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 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 investments 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 its 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 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 Portfolio are accounted for on a trade date basis. (g) Reclassification -- Accounting principles generally accepted in the United States of America require that certain components of net assets be adjusted to reflect permanent differences between financial and tax reporting. Accordingly, the current year's permanent book/tax differences of $5,478,004 have been reclassified between paid-in capital in excess of par and accumulated net investment loss and $1,989,387 has been reclassified between paid-in capital in excess of par and accumulated net realized capital losses. These reclassifications have no effect on net assets or net asset values per share. 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"), a wholly-owned subsidiary of Merrill Lynch & Co., Inc. ("ML & Co."), which is the limited partner. The Fund pays a monthly fee at an annual rate of ..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 18 MERRILL LYNCH LARGE CAP CORE FUND OCTOBER 31, 2003 Notes to Financial Statements (continued) Merrill Lynch Large Cap Core Fund 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% - -------------------------------------------------------------------------------- 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. The ongoing account maintenance fee compensates the Distributor and MLPF&S for providing account maintenance services to Class A, Class B, Class C and Class R shareholders. The ongoing distribution fee compensates the Distributor and MLPF&S for providing shareholder and distribution-related services to Class B, Class C and Class R shareholders. Financial Data Services, Inc. ("FDS"), an indirect, wholly-owned subsidiary of ML & Co., is the Fund's transfer agent. For the year ended October 31, 2003, FAMD earned underwriting discounts and MLPF&S earned dealer concessions on sales of the Fund's Class A and Class I Shares as follows: - -------------------------------------------------------------------------------- FAMD MLPF&S - -------------------------------------------------------------------------------- Class A ............................ $ 13,145 $187,010 Class I ............................ $ 103 $ 1,539 - -------------------------------------------------------------------------------- For the year ended October 31, 2003, MLPF&S received contingent deferred sales charges of $931,410, of which $2,416 was retained by the Fund as a credit, pursuant to the National Association of Securities Dealers, Inc.

See Notes to Financial Statements. 28 MERRILL LYNCH LARGE CAP CORE FUND OCTOBER 31, 2003 Notes to Financial Statements Master Large Cap Core Portfolio 1. Significant Accounting Policies: Master Large Cap Core 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. 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 Fund, 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 Fund'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 asset value 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 asset value. 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. (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 MERRILL LYNCH LARGE CAP CORE FUND OCTOBER 31, 2003 29 [LOGO] Merrill Lynch Investment Managers Notes to Financial Statements (continued) Master Large Cap Core Portfolio 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 is authorized to 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 is authorized to 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 classified as a partnership 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. (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 collects 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, 30 MERRILL LYNCH LARGE CAP CORE FUND OCTOBER 31, 2003 Notes to Financial Statements (concluded) Master Large Cap Core Portfolio 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 based upon the average daily value of the Portfolio's net assets at an annual rate of .50% of the average daily net assets not exceeding $1 billion and .45% of average daily net assets in excess of $1 billion. 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 October 31, 2003, the Portfolio lent securities with a value of $80,935,864 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 year ended October 31, 2003, MLIM, LLC received $94,660 in securities lending agent fees. For the year ended October 31, 2003, the Portfolio reimbursed FAM $23,219 for certain accounting services. Certain officers and/or trustees of the Trust are officers and/or directors of FAM, PSI, and/or ML & Co. 3. Investments: Purchases and sales of investments, excluding short-term securities, for the year ended October 31, 2003 were $1,817,565,808 and $1,514,900,598, respectively. Net realized gains for the year ended October 31, 2003 and net unrealized gains as of October 31, 2003 were as follows: - -------------------------------------------------------------------------------- Realized Unrealized Gains Gains - -------------------------------------------------------------------------------- Long-term investments .............. $ 7,803,027 $268,896,905 ---------------------------------- Total .............................. $ 7,803,027 $268,896,905 ================================== As of October 31, 2003, net unrealized appreciation for Federal income tax purposes aggregated $250,035,262, of which $273,449,914 related to appreciated securities and $23,414,652 related to depreciated securities.

Short-Term Borrowings: The Portfolio, along with certain other funds managed by FAM and its affiliates, is a party to a $500,000,000 credit agreement with Bank One, N.A. and certain other lenders. The Portfolio may borrow under the credit agreement to fund shareholder redemptions 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 credit agreement. Amounts borrowed under the credit agreement bear interest at a rate equal to, at each fund's election, the Federal Funds rate plus .50% or a base rate as determined by Bank One, N.A. On November 28, 2002, the credit agreement was renewed for one year under the same terms, except that the commitment was reduced from $1,000,000,000 to $500,000,000. The Portfolio did not borrow under the credit agreement during the year ended October 31, 2003.

These financial statements and financial highlights are the responsibility of the Portfolio'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 from 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 October 31, 2003, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. 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 Master Large Cap Core Portfolio as of October 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 the respective periods then ended, in conformity with accounting principles generally accepted in the United States of America.
