The 12th consecutive interest rate hike since June 2004 came on November 1, bringing the target federal funds rate to 4%. The central bank is clearly more focused on inflationary figures than on economic growth, which has shown some signs of moderating. Despite rising short-term interest rates and record-high energy prices, the major market indexes managed to post positive results for the current reporting period: Total Returns as of October 31, 2005 6-month 12-month ====================================================================================== U.S. equities (Standard & Poor's 500 Index) + 5.27% + 8.72% - -------------------------------------------------------------------------------------- Small-cap U.S. equities (Russell 2000 Index) +12.25 +12.08 - -------------------------------------------------------------------------------------- International equities (MSCI Europe Australasia Far East Index) + 8.63 +18.09 - -------------------------------------------------------------------------------------- Fixed income (Lehman Brothers Aggregate Bond Index) + 0.15 + 1.13 - -------------------------------------------------------------------------------------- Tax-exempt fixed income (Lehman Brothers Municipal Bond Index) + 0.59 + 2.54 - -------------------------------------------------------------------------------------- High yield bonds (Credit Suisse First Boston High Yield Index) + 2.87 + 3.54 - -------------------------------------------------------------------------------------- The headlines in recent months focused on Hurricanes Katrina and Rita and, more recently, the nomination of Ben Bernanke to succeed Alan Greenspan as Chairman of the Fed. While the hurricanes prompted a spike in energy prices and short-term disruptions to production and spending, the longer-term economic impact is likely to be tempered. In fact, the fiscal stimulus associated with reconstruction efforts in the Gulf Coast region could add to gross domestic product growth in 2006. Notably, the uncontroversial nomination of Dr. Bernanke was well received by the markets. The U.S. equity markets remained largely range bound in 2005. Up to this point, strong corporate earnings reports and relatively low long-term bond yields have worked in favor of equities. Looking ahead, high energy prices, continued interest rate hikes, a potential consumer slowdown and/or disappointing earnings pose the greatest risks to U.S. stocks. Internationally, many markets have benefited from strong economic statistics, trade surpluses and solid finances. The bond market continued to be characterized by a flattening yield curve, although long-term yields finally began to inch higher toward period end. The 10-year Treasury yield hit 4.57% on October 31, 2005, its highest level in more than six months. Still, the difference between the two-year and 10-year Treasury yield was just 17 basis points (.17%) at period end, compared to 149 basis points a year earlier. Financial markets are likely to face continued crosscurrents in the months ahead. Nevertheless, opportunities do exist and we encourage you to work with your financial advisor to diversify your portfolio among a variety of asset types. This can help to diffuse risk while also tapping into the potential benefits of a broader range of investment alternatives. As always, we thank you for trusting Merrill Lynch Investment Managers with your investment assets. Sincerely, /s/ Robert C. Doll, Jr. Robert C. Doll, Jr. President and Trustee MERRILL LYNCH CORE PRINCIPAL PROTECTED FUND OCTOBER 31, 2005 3 A Discussion With Your Fund's Portfolio Manager The Fund met its objective of preserving investor principal while also outperforming its all-equity benchmark and the Lipper Balanced Target Maturity Funds average for the fiscal year. How did the Fund perform during the fiscal year in light of the existing market conditions? For the 12-month period ended October 31, 2005, Merrill Lynch Core Principal Protected Fund's Class A, Class B, Class C and Class I Shares had total returns of +11.62%, +10.81%, +10.83% and +11.88%, 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 Fund outperformed its all-equity benchmark, the Russell 1000(R) Index, which posted a total return of +10.47% for the same period. The Fund also incorporates a fixed income component. During this 12-month period, the fixed income market, as measured by the Lehman Brothers Aggregate Bond Index, returned +1.13%. Notably, the Fund's results far exceeded the +1.20% return of the Lipper Balanced Target Maturity Funds category 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.) 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 past 12 months. Impressive gains in the fourth quarter of 2004 were given back in the early months of 2005 as major equity indexes struggled to find their footing. The rally that followed the conclusion of the presidential election in November 2004 was hampered by concerns over inflation, a weak U.S. dollar and continuing interest rate hikes by the Federal Reserve Board (the Fed). As of November 1, 2005, the Fed had increased the federal funds rate 12 consecutive times since June 2004, bringing the short-term interest rate target to 4%. Oil prices continued to fluctuate and achieved record highs on more than one occasion during the reporting period, leading to inflationary concerns, but also contributing to strong performance from the energy sector. January, March and April were particularly weak months for the market. May through July brought a stock market upturn, as a significant number of acquisition announcements, along with a resilient economy, solid consumer spending, a robust housing sector and solid growth in corporate profits, served to boost equities. The summer rally was short-lived, however, as the markets reacted to the uncertainty created in the aftermath of Hurricanes Katrina and Rita. Specifically, equities stalled in response to spiking energy prices, still rising interest rates, waning consumer confidence, the potential for slowing corporate profit growth and impending new leadership at the Fed as Chairman Alan Greenspan approaches the end of his 18-year tenure. Notably, the October 24 nomination of Dr. Ben Bernanke as Greenspan's replacement was well received by the markets. Still, October ended as one of the weaker months of the fiscal year. What factors most influenced Fund performance? Within the equity portion of the portfolio, we invest primarily in a diversified portfolio of large cap companies selected from securities found in the Russell 1000 Index. Stock selection contributed positively to returns in most sectors, including health care (particularly health care providers and services), financials (particularly insurance) and consumer discretionary (particularly retailers). Additionally, in the energy sector, the combination of a sector overweight and effective stock selection enhanced returns, particularly in oil, gas and consumable fuels. While stock selection and sector weightings detracted from the Fund's return in technology and consumer staples, this was more than offset by the overall positive returns in other sectors. At the individual stock level, the largest positive contributors to performance during the 12-month period were Valero Energy Corp., Humana, Inc., PacifiCare Health Systems, Sunoco, Inc. and Express Scripts, Inc. Our underweight position in Fannie Mae also had a positive impact on the Fund's performance, as this was the largest negative contributor in the Russell 1000 Index. Detracting most from the Fund's performance relative to the all-equity benchmark was Altria Group, Inc., TIBCO Software, Dell, Inc., QLogic Corp. and Cree, Inc. 4 MERRILL LYNCH CORE PRINCIPAL PROTECTED FUND OCTOBER 31, 2005 What changes were made to the Fund during the period? 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 fiscal year, the Fund's equity allocation ranged from 69.8% of total assets to 100%, and the fixed income allocation ranged from 30.4% to 0%. Within the equity portfolio, we continued to identify companies with favorable growth characteristics and earnings developments, selling at attractive relative valuations. As a result of our bottom-up stock-selection process, we increased the Portfolio's positions in technology, energy and health care while reducing exposure to the consumer discretionary, materials and consumer staples sectors. The largest purchases during the period included Exxon Mobil Corp., Intel Corp., Dell, Hewlett-Packard Co. and Texas Instruments, Inc. The largest sales included Johnson & Johnson, Chevron Corp., PacifiCare Health Systems, Monsanto Co. and Apple Computer, Inc. These transactions reflected our ongoing refinement of the portfolio, as we continue to look for stocks that best meet our investment criteria while pruning those that have deteriorated versus our original assessment. How would you characterize the Fund's position at the close of the period? As of October 31, 2005, the Fund's assets were invested 100% in equities and 0% in fixed income securities. This compared to 80.3% equities and 19.7% fixed income securities at April 30, 2005, and 69.7% equities and 30.3% fixed income at October 31, 2004. The Fund's largest overweights at period end were in the energy, information technology and health care sectors. The largest underweights were in financials, which tend to underperform in periods of rising interest rates, consumer staples, industrials and telecommunications services. Our view is that a somewhat conservative investment posture makes sense, at least until there is more evidence that the Fed is prepared to cease increasing short-term interest rates. Recently reported third-quarter gross domestic product (GDP) data showed that, contrary to investors' concerns, core inflation (which excludes food and energy prices) actually declined from the second quarter. By early 2006, we believe it will become more evident that consumers are retrenching, and that real GDP has decelerated to a more non-inflationary pace, specifically 3% or less. Having said that, we continue to believe that a highly diversified portfolio and a focus on individual security selection (rather than a more macro approach) is appropriate and should be rewarded on a relative basis.

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.) All returns for periods greater than eight years reflect this conversion. 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 waived 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, 2005 and held through October 31, 2005) 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 portfolio, the expense table example reflects the expenses of both the fund and the master portfolio 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 365.

See Notes to Financial Statements. 16 MERRILL LYNCH CORE PRINCIPAL PROTECTED FUND OCTOBER 31, 2005 Notes to Financial Statements Merrill Lynch Core Principal Protected Fund 1. Significant Accounting Policies: Merrill Lynch Core Principal Protected Fund (the "Fund") is a series 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 all or a portion of its assets in the Master Large Cap Core Portfolio (the "Portfolio"), which is a series 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, 2005 was 7.6%. 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 1(a) 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 ("OTC") markets and are valued at the last available bid price in the OTC 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 of the Trust. Such valuations and procedures will be reviewed periodically by the Board of Trustees of the Trust. 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 asked price for short positions. In cases where equity securities are traded on more than one exchange, the securities are valued on the exchange designated as the primary market by or under the authority of the Board of Trustees of the Trust. Long positions traded in the OTC market, Nasdaq Small Cap or Bulletin Board are valued at the last available bid price or yield equivalent obtained from one or more dealers or pricing services approved by the Board of Trustees of the Trust. Short positions traded in the OTC market are valued at the last available asked 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 asked 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 based upon quoted fair valuations received daily by the Fund from a pricing service or counterparty. 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 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 MERRILL LYNCH CORE PRINCIPAL PROTECTED FUND OCTOBER 31, 2005 17 Notes to Financial Statements (continued) Merrill Lynch Core Principal Protected Fund the Board of Trustees of the Trust, 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 Trust under the general supervision of the Trust's Board of Trustees. Such valuations and procedures will be reviewed periodically by the Board of Trustees of the Trust. Generally, trading in foreign securities, as well as U.S. government securities and money market instruments, is substantially completed each day at various times prior to the close of business on the 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 Trust's Board of Trustees or by the Investment Adviser using a pricing service and/or procedures approved by the Trust'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, and 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. (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 are charged to expense as the related shares are issued. (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 18 MERRILL LYNCH CORE PRINCIPAL PROTECTED FUND OCTOBER 31, 2005 Notes to Financial Statements (continued) Merrill Lynch Core Principal Protected Fund and tax reporting. Accordingly, during the current year, $2,210,546 has been reclassified between undistributed net realized capital gains and accumulated net investment loss, $17,552 has been reclassified between accumulated net investment loss and paid-in-capital, and $492,254 has been reclassified between undistributed net realized capital gains and paid-in-capital as a result of permanent differences attributable to net operating losses, nondeductible expenses, and other permanent differences. 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, 2005, FAM earned fees of $1,662,277, of which $947,146 was waived. 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"), an affiliate of FAM, 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. For the year ended October 31, 2005, MLPF&S received contingent deferred sales charges of $427,572 relating to transactions in Class B 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 and 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, 2005, the Fund reimbursed FAM $5,480 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, 2005 were $41,013,104 and $111,616,546, 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). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Trust is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Trust's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, 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, 2005, 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.

See Notes to Financial Statements. 30 MERRILL LYNCH CORE PRINCIPAL PROTECTED FUND OCTOBER 31, 2005 Notes to Financial Statements Master Large Cap Core Portfolio 1. Significant Accounting Policies: Master Large Cap Core Portfolio (the "Portfolio") is a series 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 asked price for short positions. In cases where equity securities are traded on more than one exchange, the securities are valued on the exchange designated as the primary market by or under the authority of the Board of Trustees of the Trust. Long positions traded in the over-the-counter ("OTC") market, Nasdaq Small Cap or Bulletin Board are valued at the last available bid price or yield equivalent obtained from one or more dealers or pricing services approved by the Board of Trustees of the Trust. Short positions traded in the OTC market are valued at the last available asked 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 asked 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 based upon quoted fair valuations received daily by the Portfolio from a pricing service or counterparty. 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 Trust, 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 of the Trust. Such valuations and procedures will be reviewed periodically by the Board of Trustees of the Trust. Generally, trading in foreign securities, as well as U.S. government securities and money market instruments, is substantially completed each day at various times prior to the close of business on the 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 of the Trust or by the Investment Adviser using a pricing service and/or procedures approved by the Board of Trustees of the Trust. (b) Derivative financial instruments -- The 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 MERRILL LYNCH CORE PRINCIPAL PROTECTED FUND OCTOBER 31, 2005 31 Notes to Financial Statements (continued) Master Large Cap Core Portfolio 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. (c) 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. (d) Security transactions and investment income -- Security transactions are accounted for on the date the securities are purchased or sold (the trade dates). Realized gains and losses on security transactions are determined on the identified cost basis. Dividend income is recorded on the ex-dividend dates. 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. (e) 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 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. (f) Custodian bank -- The Portfolio recorded an amount payable to the custodian bank reflecting an overnight overdraft, which resulted from a failed trade that settled the next day. 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 32 MERRILL LYNCH CORE PRINCIPAL PROTECTED FUND OCTOBER 31, 2005 Notes to Financial Statements (concluded) Master Large Cap Core Portfolio 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"), an affiliate of FAM, or its affiliates. As of October 31, 2005, the Portfolio lent securities with a value of $11,244,452 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, 2005, MLIM, LLC received $77,387 in securities lending agent fees. For the year ended October 31, 2005, the Portfolio reimbursed FAM $53,670 for certain accounting services. Certain officers and/or trustees of the Trust are officers and/or directors of FAM, PSI, MLAM U.K., ML & Co., and/or MLIM, LLC. 3. Investments: Purchases and sales of investments, excluding short-term securities, for the year ended October 31, 2005 were $2,674,748,983 and $2,184,746,762, 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 lenders, which expires November 2005 and was subsequently renewed for one year under substantially the same terms. 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 .07% 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, 2005. MERRILL LYNCH CORE PRINCIPAL PROTECTED FUND OCTOBER 31, 2005 33 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, 2005, 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 five years in the period 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). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Trust is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Trust's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of October 31, 2005, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. 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, 2005, 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 five years in the period then ended, in conformity with U.S. generally accepted accounting principles.

(the "Investment Adviser") or other Merrill Lynch affiliates is as a Trustee of the Fund and certain other funds advised by the Investment Adviser or its affiliates. The Chair of the Board is also an independent Trustee. All but one member of the Board of Trustees of Master Large Cap Core Portfolio (the "Portfolio"), the master fund into which the Fund invests a portion of its assets, the members of which are different from the Fund's Board of Trustees, is a non- interested Trustee as that term is defined in the Investment Company Act of 1940, whose only association with the Investment Adviser or other Merrill Lynch affiliates is as a Trustee of the Portfolio and of certain other funds advised by the Investment Adviser or its affiliates. The Co-chairmen of the Portfolio's Board are independent Trustees. New Trustee nominees for each Board are chosen as nominees by a Nominating Committee comprised of independent Trustees. All independent Trustees also are members of the appropriate Board's Audit Committee and the independent Trustees meet in executive session at each in-person Board meeting. Each Board and each Audit Committee meet in person for at least two days each quarter and conduct other in person and telephone meetings throughout the year, some of which are formal board meetings, and some of which are informational meetings. The independent counsel to each group of independent Trustees attends all in-person Board and Audit Committee meetings and other meetings at the independent Trustees' request. Investment Advisory Agreement -- Matters Considered by the Boards Every year the Portfolio Board considers approval of the Portfolio's investment advisory agreement. The Portfolio Board also annually reviews and considers approval of the sub-advisory agreement on behalf of the Portfolio between the Investment Adviser and an affiliate. Every year the Fund MERRILL LYNCH CORE PRINCIPAL PROTECTED FUND OCTOBER 31, 2005 37 Disclosure of Investment Advisory Agreement (continued) Board considers approval of the Fund's investment advisory agreement, taking into consideration the Portfolio's investment advisory and sub-advisory agreement (together, the "Investment Advisory Agreements"). Each Board assesses the nature, scope and quality of the services provided to the Portfolio and the Fund by the personnel of the Investment Adviser, the sub-adviser and their affiliates, including administrative services, shareholder services, oversight of fund accounting, marketing services and assistance in meeting legal and regulatory requirements. Each Board also receives and assesses information regarding the services provided to the Portfolio and the Fund by certain unaffiliated service providers. At various times throughout the year, each Board also considers a range of information in connection with its oversight of the services provided by the Investment Adviser and its affiliates, including the sub-adviser. Among the matters considered are: (a) fees (in addition to management fees) paid to the Investment Adviser and its affiliates by the Portfolio and/or the Fund, such as transfer agency fees and fees for marketing and distribution; (b) Portfolio or Fund operating expenses paid to third parties; (c) the resources devoted to and compliance reports relating to the Portfolio's and the Fund's investment objective, policies and restrictions, and its compliance with its Code of Ethics and the Investment Adviser's compliance policies and procedures; and (d) the nature, cost and character of non-investment management services provided by the Investment Adviser and its affiliates. The Board believes that the Investment Adviser is one of the most experienced global asset management firms and considers the overall services provided by the Investment Adviser to be of high quality. The Board also believes that the Investment Adviser is financially sound and well managed and notes that the Investment Adviser is affiliated with one of America's largest financial firms. The Board works closely with the Investment Adviser in overseeing the Investment Adviser's efforts to achieve good performance. As part of this effort, the Board discusses portfolio manager effectiveness and, when performance is not satisfactory, discusses with the Investment Adviser taking steps such as changing investment personnel. Annual Consideration of Approval by the Board of Trustees In the period prior to the Board meetings to consider renewal of the Investment Advisory Agreement, each Board requests and receives materials specifically relating to the Investment Advisory Agreements. These materials include (a) information compiled by Lipper Inc. ("Lipper") on the fees and expenses and the investment performance of the Fund as compared to a comparable group of funds as classified by Lipper; (b) sales and redemption data for the Fund; (c) a discussion by the Portfolio's/Fund's portfolio management team of investment strategies used by the Portfolio/Fund during its most recent fiscal year; (d) information on the profitability to the Investment Adviser and its affiliates of the Investment Advisory Agreements and other relationships with the Fund; and (e) information provided by the Investment Adviser concerning investment advisory fees charged to other clients, such as offshore funds under similar investment mandates and generally to institutional clients. Since the sub-advisory services are provided by Merrill Lynch Asset Management U.K. Limited, an affiliate of the Investment Adviser, and no additional fee is paid for these services, the Boards considered the sub-advisory agreement as part of the Investment Advisory Agreements. Each Board also considers other matters it deems important to the approval process such as payments made to the Investment Adviser or its affiliates relating to the distribution of Fund shares, services related to the valuation and pricing of Portfolio or Fund portfolio holdings, allocation of Portfolio or Fund brokerage fees, the Fund's portfolio turnover statistics, and direct and indirect benefits to the Investment Adviser and the sub-adviser and their affiliates from their relationship with the Portfolio and the Fund. Certain Specific Renewal Data In connection with the most recent renewal of the Investment Advisory Agreements in May 2005, the independent Trustees' and Board's review included the following: Services Provided by the Investment Adviser -- Each Board reviewed the nature, extent and quality of services provided by the Investment Adviser, including the investment advisory services and the resulting performance of the Portfolio and the Fund. Each Board focused primarily on the Investment Adviser's investment advisory services and the Portfolio's/ Fund's investment performance. Each Board compared Fund performance -- both including and excluding the effects of the Fund's fees and expenses -- to the performance of a comparable group of funds, and the performance of a relevant index or combination of indexes. While each Board reviews performance data at least quarterly, consistent with the Investment Adviser's investment goals, the Board attaches more importance to performance over relatively long periods of time, typically three to five years or, in the case of a fund that has been in existence for less than three years, performance since inception. The Fund's performance 38 MERRILL LYNCH CORE PRINCIPAL PROTECTED FUND OCTOBER 31, 2005 Disclosure of Investment Advisory Agreement (concluded) after fees and expenses ranked in the first quintile for the one-year period ended March 31, 2005 and the first quintile for the period since inception through March 31, 2005. Considering these factors, each Board concluded that the Fund's performance supported the continuation of the Investment Advisory Agreements. The Investment Adviser's Personnel and Investment Process -- Each Board reviews at least annually the Portfolio's/Fund's investment objectives and strategies. Each Board discusses with senior management of the Investment Adviser responsible for investment operations and the senior management of the Investment Adviser's equity investing group the strategies being used to achieve the stated objectives. Among other things, each Board considers the size, education and experience of the Investment Adviser's investment staff, its use of technology, and the Investment Adviser's approach to training and retaining portfolio managers and other research, advisory and management personnel. Each Board also reviews the Investment Adviser's compensation policies and practices with respect to the Portfolio's and the Fund's portfolio managers. Each Board also considered the experience of the Portfolio's and the Fund's portfolio manager and noted that Mr. Doll has more than 20 years experience in portfolio management. The Investment Adviser and its investment staff have extensive experience in analyzing and managing the types of investments used by the Portfolio and the Fund. Each Board concluded that each of the Portfolio and the Fund benefits from that expertise. Management Fees and Other Expenses -- Each Board reviews the Fund's contractual management fee rate and actual management fee rate as a percentage of total assets at common asset levels -- the actual rate includes advisory and administrative service fees and the effects of any fee waivers -- compared to the other funds in its Lipper category. It also compares the Fund's total expenses to those of other comparable funds. Each Board considered the services provided to and the fees charged by the Investment Adviser to other types of clients such as off-shore funds, with similar investment mandates and noted that the fees charged by the Investment Adviser in those cases typically exceeded those being charged to the Fund. Each Board also noted that, as a general matter, fees charged to institutional clients were lower than the fees charged to the Fund, but believed that less extensive services were being provided to such clients. The Fund's contractual management fees and total expenses were equal to the median of fees and expenses charged by comparable funds as determined by Lipper. The Fund's actual management fees were higher than the median fees of such comparable funds. Each Board has concluded that the Portfolio's and the Fund's management fees and fee rates and overall expense ratios were reasonable compared to those of other comparable funds. Profitability -- Each Board considers the cost of the services provided to the Portfolio and the Fund by the Investment Adviser, and the Investment Adviser's and its affiliates' profits relating to the management and distribution of the Fund and the MLIM/FAM-advised funds. As part of its analysis, the Board reviewed the Investment Adviser's methodology in allocating its costs to the management of the Fund and concluded that there was a reasonable basis for the allocation. Each Board believes the Investment Adviser's profits are reasonable in relation to the nature and quality of services provided. Each Board also considered the federal court decisions discussing an investment adviser's profitability and profitability levels considered to be reasonable in those decisions. Economies of Scale -- Each Board considered the extent to which economies of scale might be realized as the assets of the Portfolio/Fund increase and whether there should be changes in the management fee rate or structure in order to enable the Portfolio/Fund to participate in these economies of scale. Each Board noted that the Portfolio's management fee schedule includes breakpoints that reduce the management fee rate as the Portfolio's assets increase above certain levels. The Boards also noted that such breakpoints should allow the Fund to share in such economies of scale as its assets increase. The Fund Board also considered the Investment Adviser's agreement to waive the Fund's advisory fee by the amount it pays to the Portfolio's investment adviser. The Fund Board also noted that if all the Fund's assets are irreversibly allocated to the Fund's Protection Component under the terms of the Warranty Agreement, the management fee will be reduced to 0.25%. While there was no evidence to date that the Portfolio's or the Fund's assets have reached a level where such economies are effectively available, each Board will continue to seek information relating to economies of scale. Conclusion After the independent Trustees deliberated in executive session, the entire Board of each of the Portfolio and the Fund, including all of the independent Trustees, approved the renewal of the existing Investment Advisory Agreements, including the sub-advisory agreement, concluding that the advisory fee was reasonable in relation to the services provided and that a contract renewal was in the best interests of the applicable shareholders.
