At the top of investors' minds were questions about economic expansion, corporate earnings, interest rates and inflation, politics, oil prices and terrorism. After benefiting from aggressive monetary and fiscal policy stimulus, some fear the U.S. economy has hit a "soft patch." In fact, economic expansion has slowed somewhat in recent months, but we believe it is easing into a pace of growth that is sustainable and healthy. The favorable economic environment has served to benefit American corporations, which have continued to post strong earnings. Although the most impressive results were seen earlier in the year, solid productivity, improved revenue growth and cost discipline all point to a vital corporate sector. In terms of inflation and interest rates, the Federal Reserve Board (the Fed) has signaled its confidence in the economic recovery by increasing the Federal Funds target rate four times in the past several months, from 1% to 2% as of the November 10 Federal Open Market Committee meeting. Inflation, for its part, has remained in check. Investors and economists are focused on how quickly monetary policy will move from here, anxiously absorbing every bit of economic data and Fed innuendo. With the presidential election now behind us, any politically provoked market angst should subside to some extent. The effect of oil prices, however, is more difficult to predict. At around $50 per barrel, the price of oil is clearly a concern. However, on an inflation-adjusted basis and considering modern usage levels, the situation is far from the crisis proportions we saw in the 1980s. Finally, although terrorism and geopolitical tensions are realities we are forced to live with today, history has shown us that the financial effects of any single event tend to be short-lived. Amid the uncertainty, the Standard & Poor's 500 Index returned +9.42% for the 12-month period and +2.96% for the six-month period ended October 31, 2004. As always, our investment professionals are closely monitoring the markets, the economy and the overall environment in an effort to make well-informed decisions for the portfolios they manage. For the individual investor, the key during uncertain times is to remain focused on the big picture. While tracking current events is important, investment success comes not from reacting to short-term volatility, but from maintaining a long-term perspective and adhering to the disciplines of asset allocation, diversification and rebalancing. We encourage you to work with your financial advisor to ensure these time-tested techniques are incorporated into your investment plan. We thank you for trusting Merrill Lynch Investment Managers with your investment assets, and we look forward to serving you in the months and years ahead. Sincerely, /s/ Terry K. Glenn Terry K. Glenn President and Trustee MERRILL LYNCH CORE PRINCIPAL PROTECTED FUND OCTOBER 31, 2004 3 [LOGO] Merrill Lynch Investment Managers A Discussion With Your Fund's Portfolio Manager The Fund outperformed the Lipper Balanced Target Maturity Funds average return for the fiscal year while effectively meeting its objective of preserving investor principal. What is the Fund's investment objective? The Fund seeks long-term capital growth while protecting the principal value of investor shares. This is accomplished through investments in a core equity component (equity securities of large-capitalization companies) and a protection component (fixed income investments that have financial characteristics resembling a portfolio of zero-coupon bonds). A mathematical formula is used to determine the allocation between these two components. During the period, the Portfolio's equity allocation ranged from 58.2% of total assets to 73.3%, and the fixed income allocation ranged from 26.7% to 41.8%. How did the Fund perform during the fiscal year in light of the existing market conditions? For the 12-month period ended October 31, 2004, Merrill Lynch Core Principal Protected Fund's Class A, Class B, Class C and Class I Shares had total returns of +4.14%, +3.36%, +3.37% and +4.44%, 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 - 8 of this report to shareholders.) The Russell 1000 Index, a widely used, all-equity benchmark, had a total return of +9.33% for the same period. Because the Fund incorporates a fixed income component, which is not reflected in the Russell 1000 Index, it will at times outperform or underperform that benchmark. The Fund outperformed its comparable Lipper category of Balanced Target Maturity Funds, which had an average return of +2.50% for the 12-month period. (Funds in this Lipper category invest to provide a guaranteed return of investment at maturity. Some of the assets are invested in zero-coupon U.S. Treasury securities, while the remainder is in equity securities for long-term growth of capital and income.) Notably, for the six-month period ended October 31, 2004, the Fund outperformed the Russell 1000 Index and the Lipper category average. The Fund's Class A, Class B, Class C and Class I Shares had total returns of +4.00%, +3.56%, +3.56% and +4.17%, respectively, for the six months ended October 31, 2004. This compared to a return of +3.04% for the Russell 1000 and +1.57% for the Lipper Balanced Target Maturity Funds average. 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. Essentially, the past year could be viewed as two distinct periods. The stock market performed strongly in the first six months, carrying the momentum from year-end 2003 into the new year. Specifically, equities gleaned support from favorable economic news, unprecedented fiscal and monetary policy stimulus, extraordinary corporate earnings results, strong money flows and attractive valuations. In the six months that followed, the market was much more volatile, taking its cues from election-related uncertainty, violence in Iraq, record-high oil prices, rising interest rates and a series of soft economic data. Over the course of the year, we witnessed a "flight to quality," whereby investor favor shifted from low-quality, low-price and higher-risk securities early in 2004 to higher-quality, higher-cap and lower-risk stocks as investors became more cautious. Looking ahead, we believe good stock picking will rely more on evaluating underlying company fundamentals, with no clear winners in terms of sector, style or market cap size. What were the primary factors that influenced Fund performance? Within the equity portfolio, positive performance came from stock selection in the utilities, healthcare and consumer discretionary sectors, especially specialty retailers. This was partially offset by stock selection in information technology and financials, especially insurance-related stocks. At the individual stock level, the largest positive contributors to performance included American Eagle Outfitters, Inc., Urban Outfitters, Inc., Nordstrom, Inc., Oxford Health Plans, Inc., Norfolk Southern Corporation and Autodesk, Inc. The largest detractors from performance included Humana Inc., ITT Educational Services, Inc., Amkor Technology, Inc., SanDisk Corporation and Cypress Semiconductor Corporation. In addition, an underweight position in Merck & Co., Inc. benefited performance, while an underweighting in Exxon Mobil Corporation negatively affected performance. 4 MERRILL LYNCH CORE PRINCIPAL PROTECTED FUND OCTOBER 31, 2004 What changes were made to the Portfolio during the year? In the equity portion of the portfolio, we maintained a procyclical bias for the majority of the fiscal year, investing in those companies and sectors that we believed could benefit from a burgeoning U.S. economy. For the most part, portfolio activity involved fine-tuning our exposures based on our fundamental research, including the use of both qualitative and quantitative screens. Although we continue to believe the U.S. economy is on relatively solid footing, we had moderated our cyclical focus to some extent by period-end as investors grew somewhat more cautious. From a sector perspective, we increased our positions relative to the Russell 1000 Index in energy and materials, and ended the period overweight in these industries. We also increased our exposure to consumer staples, a more defensive sector, although we remain underweight in this area. We reduced our positions relative to the benchmark in information technology and consumer discretionary, but remain overweight in these sectors, and also trimmed our exposure to industrials. In terms of individual stocks, we continued to search for companies with what we viewed as good earnings momentum and compelling valuations. The largest purchases during the period included Johnson & Johnson, Pfizer, Inc., ChevronTexaco Corporation, Anthem, Inc., Hewlett-Packard Company, Countrywide Credit Industries, Inc. and Lucent Technologies, Inc. The largest sales included Cisco Systems, Inc., Citigroup Inc., Sprint Corp. (PCS), QUALCOMM Incorporated, J.P. Morgan Chase & Co. and Apollo Group, Inc. The fixed income component of the Portfolio was invested in U.S. Treasury zero-coupon bonds set to mature close to the expiration of the Fund (February 28, 2010). How would you characterize the Portfolio's position at the close of the period? At the end of the period, Portfolio assets were invested 69.7% in equities and 30.3% in fixed income securities. In the equity component, we generally maintained our focus on cyclical stocks in anticipation of positive economic developments and continued strong earnings growth. Some observers have come to question the vitality of economic growth in recent months, citing negligible inflation, slowing consumer spending and record-high oil prices. However, we continue to believe that the foundations of the economy are reasonably strong and corporate balance sheets are in good shape. Corporations continue to post earnings increases well above the historical average of 7%. At this time, the market has already found some relief in the conclusion of the presidential election. Investors appear to have viewed the re-election of President Bush as a positive for American businesses. Based on our relatively optimistic view, our largest overweights as of October 31, 2004, were in consumer discretionary, energy and materials -- areas 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 consumer staples. We remain focused on our search for companies exhibiting good earnings momentum, earnings surprise and favorable valuation characteristics, and that we believe are positioned to deliver strong performance over the long term. At the same time, the Fund remains committed to its goal of protecting investor principal. Robert C.

In addition, Class B Shares are subject to a distribution fee of 0.75% per year and an account maintenance fee of 0.25% per year. 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% per year and an account maintenance fee of 0.25% per year. 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. None of the past results shown should be considered a representation of future performance. Current performance may be lower or higher than the performance data quoted. Refer to www.mlim.ml.com to obtain performance data current to the most recent month-end. Performance results do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. Figures shown in each of the following tables assume reinvestment of all dividends and capital gain distributions, if any, at net asset value on the ex-dividend date. The Fund's Investment Adviser reimbursed a portion of the Fund's expenses. Without such waiver, the Fund's performance would have been lower. Investment return and principal value of shares will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. Dividends paid to each class of shares will vary because of the different levels of account maintenance, distribution and transfer agency fees applicable to each class, which are deducted from the income available to be paid to shareholders.

The following example (which is based on a hypothetical investment of $1,000 invested on May 1, 2004 and held through October 31, 2004) is intended to assist shareholders both in calculating expenses based on an investment in the Fund and in comparing these expenses with similar costs of investing in other mutual funds: The first table below provides information about actual account values and actual expenses. In order to estimate the expenses a shareholder paid during the period covered by this report, shareholders can divide their account value by $1,000 and then multiply the result by the number in the first line under the heading entitled "Expenses Paid During the Period." The second table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses. In order to assist shareholders in comparing the ongoing expenses of investing in this Fund and other funds, compare the 5% hypothetical example with the 5% hypothetical examples that appear in other funds' shareholder reports. The expenses shown in the table are intended to highlight shareholders ongoing costs only and do not reflect any transactional expenses, such as sales charges, redemption fees, or exchange fees. Therefore, the second table is useful in comparing ongoing expenses only, and will not help shareholders determine the relative total expenses of owning different funds. If these transactional expenses were included, shareholder expenses would have been higher.

Because the Fund invests significantly in a master fund, the expense table example reflects the expenses of both the fund and the master fund in which it invests. ** Hypothetical 5% annual return before expenses is calculated by pro-rating the number of days in the most recent fiscal half-year divided by 364.

See Notes to Financial Statements. 16 MERRILL LYNCH CORE PRINCIPAL PROTECTED FUND OCTOBER 31, 2004 Notes to Financial Statements Merrill Lynch Core Principal Protected Fund 1. Significant Accounting Policies: Merrill Lynch Core Principal Protected Fund (the "Fund") is part of Merrill Lynch Principal Protected Trust (the "Trust"). Under the Investment Company Act of 1940, as amended, the Fund is diversified and the Trust is registered as an open-end management investment company. The Fund invests a portion of its assets in the Master Large Cap Core Portfolio (the "Portfolio"), which is a portfolio of Master Large Cap Series Trust. 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 U.S. generally accepted accounting principles, which may require the use of management accruals and estimates. Actual results may differ from these estimates. The percentage of the Portfolio owned by the Fund at October 31, 2004 was 8.9%. The Fund offers multiple classes of shares. Shares of the Fund were offered during the initial offering period but will not be offered during the Guarantee Period from February 28, 2003 through February 28, 2010 (the "Guarantee Maturity Date"), except in connection with reinvestment of dividends and distributions. The Fund will be offered on a continuous basis after the Guarantee Maturity Date. 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. All classes of shares have identical voting, dividend, liquidation and other rights and the same terms and conditions, except that Class A, Class B and Class C Shares bear certain expenses related to the account maintenance of such shares, and Class B and Class C 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 (except that Class B shareholders may vote on material changes to the Class A distribution plan). 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. Debt securities are traded primarily in the over-the-counter markets and are valued at the last available bid price in the over-the-counter market or on the basis of values obtained by a pricing service. Pricing services use valuation matrixes that incorporate both dealer-supplied valuations and valuation models. The procedures of the pricing service and its valuations are reviewed by the officers of the Fund under the general direction of the Board of Trustees. Such valuations and procedures will be reviewed periodically by the Board of Trustees. Equity securities that are held by the Fund 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 Fund. 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 Fund. 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. MERRILL LYNCH CORE PRINCIPAL PROTECTED FUND OCTOBER 31, 2004 17 [LOGO] Merrill Lynch Investment Managers Notes to Financial Statements (continued) Merrill Lynch Core Principal Protected Fund Repurchase agreements are valued at cost plus accrued interest. The Fund employs pricing services to provide certain securities prices for the Fund. 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 Fund, 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 Fund 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 Fund. 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 Fund'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 Fund'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 Fund's Board of Trustees or by the Investment Adviser using a pricing service and/or procedures approved by the Fund's Board of Trustees. (b) Derivative financial instruments -- The Fund may engage in various portfolio investment strategies both to increase the return of the Fund 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 Fund 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 Fund deposits and maintains as collateral such initial margin as required by the exchange on which the transaction is effected. Pursuant to the contract, the Fund 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 Fund as unrealized gains or losses. When the contract is closed, the Fund 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 Fund may write and purchase call and put options. When the Fund writes an option, an amount equal to the premium received by the Fund 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 Fund enters into a closing transaction), the Fund realizes a gain or loss on the option to the extent of the premiums received or paid (or gain or loss to the extent the cost of the closing transaction exceeds the premium paid or received). Written and purchased options are non-income producing investments. 18 MERRILL LYNCH CORE PRINCIPAL PROTECTED FUND OCTOBER 31, 2004 Notes to Financial Statements (continued) Merrill Lynch Core Principal Protected Fund (c) Security transactions, investment income and expenses -- Security transactions are recorded on the dates the transactions are entered into (the trade dates). Investment transactions in the Portfolio are accounted for on a trade date basis. 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. The Fund amortizes all premiums and discounts on debt securities. 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. (d) 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. (e) Prepaid registration fees -- Prepaid registration fees will be amortized over a 12-month period beginning with the commencement of operations of the Fund. (f) Dividends and distributions -- Dividends and distributions paid by the Fund are recorded on the ex-dividend dates. (g) Reclassifications -- U.S. generally accepted accounting principles require that certain components of net assets be adjusted to reflect permanent differences between financial and tax reporting. Accordingly, during the current year, $1,334,357 has been reclassified between undistributed realized capital gains and accumulated investment loss, and $5,643 has been reclassified between paid-in-capital and accumulated investment loss as a result of permanent differences attributable to net operating losses and nondeductible expenses. These reclassifications have no effect on net assets or net asset values per share. 2. Investment Advisory Agreements and Transactions with Affiliates: The Fund 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. The Fund has also 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. FAM is responsible for the management of the Fund's portfolio and provides the necessary personnel, facilities, equipment and certain other services necessary to the operations of the Fund. For such services, the Fund pays a monthly fee at the annual rate of .75% of the Fund's average daily net assets. FAM has contractually agreed to waive its management fee by the amount of management fees the Fund pays FAM indirectly through its investment in the Portfolio. For the year ended October 31, 2004, FAM earned fees of $1,948,544 and waived $842,754. In addition, FAM has entered into a contractual arrangement with the Fund under which the expenses incurred by each class of shares of the Fund (excluding distribution and/or account maintenance fees) will not exceed 1.99%. This arrangement has a one-year term and is renewable. 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% - -------------------------------------------------------------------------------- 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 and Class C shareholders. The ongoing distribution fee compensates the Distributor and MLPF&S for providing shareholder and distribution-related services to Class B and Class C shareholders. MERRILL LYNCH CORE PRINCIPAL PROTECTED FUND OCTOBER 31, 2004 19 [LOGO] Merrill Lynch Investment Managers Notes to Financial Statements (continued) Merrill Lynch Core Principal Protected Fund For the year ended October 31, 2004, MLPF&S received contingent deferred sales charges of $463,441 and $108 relating to transactions in Class B and Class C Shares, respectively. Furthermore, MLPF&S received contingent deferred sales charges of $71,809 relating to transactions subject to front-end sales charge waivers in Class A Shares. The Trust, on behalf of the Fund, and FAM have entered into a Financial Warranty Agreement with Ambac Assurance Corporation ("Ambac"). The Financial Warranty Agreement is intended to make sure that on the Guarantee Maturity Date, each shareholder of the Fund will be entitled to redeem his or her shares for an amount no less than the initial value of that shareholder's account (less expenses and sales charges not covered by the Financial Warranty Agreement), provided that all dividends distributions received from the Fund have been reinvested and no shares have been redeemed (the "Guaranteed Amount"). The Fund will pay to Ambac, under the Financial Warranty Agreement, an annual fee equal to .625% of the Fund's average daily net assets during the Guarantee Period. If the value of the Fund's assets on the Guarantee Maturity Date is insufficient to result in the value of each shareholder's account being at least equal to the shareholder's Guaranteed Amount, Ambac will pay the Fund an amount sufficient to make sure that each shareholder's account can be redeemed for an amount equal to his or her Guaranteed Amount. 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, 2004, the Fund reimbursed FAM $5,423 for certain accounting services. Certain officers and/or trustees of the Fund are officers and/or directors of FAM, FAMD, FDS, PSI, and/or ML & Co. 3. Investments: Purchases and sales of investments, excluding short-term securities and investments in the Portfolio, for the year ended October 31, 2004 were $144,475,449 and $153,511,465, respectively. 4. Beneficial Interest Transactions: Net increase (decrease) in net assets derived from beneficial interest transactions was $(55,153,321) and $253,589,048 for the year ended October 31, 2004 and for the period February 28, 2003 to October 31, 2003, respectively.

These financial statements and financial highlights are the responsibility of the Trust's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States).

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, 2004, 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 Merrill Lynch Core Principal Protected Fund of Merrill Lynch Principal Protected Trust as of October 31, 2004, the results of its operations for the year then ended, and the changes in its net assets and its financial highlights for the year then ended and for the period February 28, 2003 through October 31, 2003, in conformity with U.S. generally accepted accounting principles.

See Notes to Financial Statements. 32 MERRILL LYNCH CORE PRINCIPAL PROTECTED FUND OCTOBER 31, 2004 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 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 Portfolio, subject to certain limitations. The Portfolio's financial statements are prepared in conformity with U.S. generally accepted accounting principles, which may require the use of management accruals and estimates. Actual results may differ from these estimates. The 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. 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. 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, 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 Trust under the general supervision of the Board of Trustees. Such valuations and procedures will be reviewed periodically by the Board of Trustees. 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 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 Board of Trustees or by the Investment Adviser using a pricing service and/or procedures approved by the 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 initial margin as required by the exchange on which the MERRILL LYNCH CORE PRINCIPAL PROTECTED FUND OCTOBER 31, 2004 33 [LOGO] Merrill Lynch Investment Managers Notes to Financial Statements (continued) Master Large Cap Core Portfolio 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 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, 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 34 MERRILL LYNCH CORE PRINCIPAL PROTECTED FUND OCTOBER 31, 2004 Notes to Financial Statements (concluded) Master Large Cap Core Portfolio 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 not exceeding $1 billion and .45% of average daily net assets in excess of $1 billion. 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. 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, 2004, MLIM, LLC received $87,678 in securities lending agent fees. In addition, MLPF&S received $5,400 in commissions on the execution of portfolio security transactions for the Portfolio for the year ended October 31, 2004. For the year ended October 31, 2004, the Portfolio reimbursed FAM $33,710 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, 2004 were $2,457,789,310 and $2,212,078,496, respectively. 4. 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 a group of 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 portfolio's election, the Federal Funds rate plus .50% or a base rate as defined in the credit agreement. The Portfolio did not borrow under the credit agreement during the year ended October 31, 2004. On November 26, 2004, the credit agreement was renewed for one year under substantially the same terms. MERRILL LYNCH CORE PRINCIPAL PROTECTED FUND OCTOBER 31, 2004 35 [LOGO] Merrill Lynch Investment Managers Report of Independent Registered Public Accounting Firm Master Large Cap Core Portfolio To the Investors and Board of Trustees of Master Large Cap Series Trust: We have audited the accompanying statement of assets and liabilities, including the schedule of investments of Master Large Cap Core Portfolio, one of the portfolios constituting Master Large Cap Series Trust (the "Trust"), as of October 31, 2004, the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the respective periods then ended. These financial statements and financial highlights are the responsibility of the Trust's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States).

Our procedures included confirmation of securities owned as of October 31, 2004, 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 of Master Large Cap Series Trust, as of October 31, 2004 the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and its financial highlights for each of the respective periods then ended, in conformity with U.S. generally accepted accounting principles.

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 all of the registrants the Committee oversees. 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.
