Index performance shown for illustrative purposes only. You cannot invest directly in an index. Subprime mortgage woes dominated headlines for much of 2007, but intensified in the summer and fall, spawning a widespread liquidity and credit crisis with ramifications across global markets. The Federal Reserve Board (the "Fed") and other countries' central banks stepped in to inject liquidity into the markets and bolster investor confidence. The Fed cut the federal funds rate by 0.50% in September and another 0.25% on the final day of the reporting period, bringing its target rate to 4.50%. In taking action, the central bankers, who had long deemed themselves inflation fighters, were seeking to stem the fallout from the credit crunch and forestall a wider economic unraveling. By period-end, the Fed had cited the risks between slower economic growth and faster inflation as equally balanced. Amid the volatility throughout the past year, equity markets have displayed surprising resilience. Most recently, the credit turmoil dampened corporate merger-and-acquisition (M&A) activity, a key source of strength for equity markets. Still, market fundamentals have held firm, dividend payouts and share buybacks have continued to grow, and valuations remain attractive. These tailwinds generally have prevailed over the headwinds created by the slowing U.S. economy, troubled housing market and, recently, a more difficult corporate earnings backdrop. International markets fared even better than U.S. equities, benefiting from robust M&A activity and generally stronger economies. In fixed income markets, mixed economic signals and the credit woes resulted in a flight to quality. At the height of the uncertainty, investors shunned bonds associated with the housing and credit markets in favor of higher-quality Treasury issues. The yield on 10-year Treasury issues, which touched 5.30% in June (its highest level in five years), fell to 4.48% by period-end, while prices correspondingly rose. The tax-exempt bond market has been challenged by a combination of record-setting supply year-to-date, economic uncertainty and concerns around the credit worthiness of bond insurers. This has brought municipal bond prices to relatively attractive levels and, as such, demand generally has remained firm. As you navigate market volatility, we encourage you to review your investment goals with your financial professional and to make portfolio changes, as needed.

As always, we thank you for entrusting BlackRock with your investment assets, and we look forward to continuing to serve you in the months and years ahead. Sincerely, /s/ Robert C.

Throughout the 12-month period, the Fund's equity allocation remained at 100% of net assets and the fixed income allocation at 0% through its investment in Master Large Cap Core Portfolio. What factors influenced performance? o At a very high level, strong performance generated by asset allocation decisions was offset by disappointing stock selection results. o Favorable asset allocation decisions included overweight positions in energy and information technology, and an underweight in financials. The Fund's weighting in financials is significantly below that of the benchmark, particularly in commercial banks and mortgage companies. o Stock selection within the health care sector enhanced performance, particularly in biotechnology companies and service providers. Stock selection within industrials and materials also contributed positively to returns. The largest individual contributors to performance were Southern Copper Corp., Tesoro Corp., EMC Corp., The Goodyear Tire & Rubber Co. and Frontier Oil Corp. o Stock selection in energy and information technology (IT) offset the aforementioned gains stemming from allocation decisions in these sectors. Within energy, recent underperformance is attributed largely to the refiners, which came under pressure in the third quarter of 2007 as margins were expected to compress. However, we believed that refiners were oversold and added to some of our positions on price weakness. Within technology, our lack of ownership of a few outperforming companies and stock-specific disappointments in the semiconductor, software and IT services areas hurt performance. The largest individual detractors were Apple Inc., Lexmark International, Inc., BEA Systems Ltd., RadioShack Corp. and Electronic Data Systems Corp. o The Fund's overweight position and stock selection in consumer discretionary proved negative for the period. Given ongoing concerns about consumer spending, we shifted the cyclical bias of the Fund away from the domestic consumer and toward more global, industrial-based companies. Describe recent portfolio activity. o During the period, we increased the Fund's exposure to information technology and telecommunication services. Among our largest purchases were American International Group, Inc., ConocoPhillips Co., UnitedHealth Group, Inc., Valero Energy Corp. and Applied Materials, Inc. o We reduced exposure to the consumer discretionary, energy, financials, industrials, consumer staples and materials sectors. Our largest sales included JPMorgan Chase & Co., Biogen Idec, Inc., Morgan Stanley, CSX Corp. and The Goldman Sachs Group, Inc. Describe the Fund's positioning at period-end. o Relative to the Russell 1000 Index, the Fund ended its fiscal year overweight in information technology, health care, consumer discretionary and energy, and underweight in financials, consumer staples, utilities and telecommunication services. o In our view, stocks are now more susceptible to economic and earnings disappointments than they were during the initial stages of the Federal Reserve Board's easing cycle. However, we believe more monetary relief should be in the pipeline, as economic conditions warrant further stimulus. Importantly, we do not believe inflation stands in the way of more rate cuts. As the economic data worsens, reflation should strengthen as the dominant market force, setting the stage for higher valuations.

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.

Performance information reflects past performance and does not guarantee future results. Current performance may be lower or higher than the performance data quoted. Refer to www.blackrock.com/funds 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. Performance data does not reflect this potential fee. Figures shown in the performance tables on page 5 assume reinvestment of all dividends and capital gain distributions, if any, at net asset value on the ex-dividend date. Investment return and principal value of shares will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. Dividends paid to each class of shares will vary because of the different levels of service, distribution and transfer agency fees applicable to each class, which are deducted from the income available to be paid to shareholders. Disclosure of Expenses Shareholders of this Fund may incur the following charges: (a) expenses related to transactions, including sales charges, redemption fees and exchange fees; and (b) operating expenses including advisory fees, distribution fees including 12b-1 fees, and other Fund expenses. The expense example on page 4 (which is based on a hypothetical investment of $1,000 invested on May 1, 2007 and held through October 31, 2007) 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 table 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 corresponding to their share class under the heading entitled "Expenses Paid During the Period." The table also 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 hypothetical 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. 6 BLACKROCK CORE PRINCIPAL PROTECTED FUND OCTOBER 31, 2007 Statement of Assets and Liabilities BlackRock Core Principal Protected Fund As of October 31, 2007 ==================================================================================================================================== Assets - ------------------------------------------------------------------------------------------------------------------------------------ Investment in Master Large Cap Core Portfolio (the "Portfolio"), at value (identified cost -- $127,654,898*) ........................................................... $ 162,342,746 Prepaid expenses ............................................................................... 918 -------------- Total assets ................................................................................... 162,343,664 -------------- ==================================================================================================================================== Liabilities - ------------------------------------------------------------------------------------------------------------------------------------ Payables: Distributor ................................................................................ $ 126,426 Financial warranty fee ..................................................................... 85,943 Advisory fee ............................................................................... 40,686 Other affiliates ........................................................................... 18,451 271,506 -------------- Accrued expenses ............................................................................... 32,690 -------------- Total liabilities .............................................................................. 304,196 -------------- ==================================================================================================================================== Net Assets - ------------------------------------------------------------------------------------------------------------------------------------ Net Assets ..................................................................................... $ 162,039,468 ============== ==================================================================================================================================== Net Assets Consist of - ------------------------------------------------------------------------------------------------------------------------------------ Paid-in capital, unlimited shares of no par value authorized ................................... $ 100,882,687 Undistributed realized capital gains -- net .................................................... $ 26,468,933 Unrealized appreciation -- net ................................................................. 34,687,848 -------------- Total accumulated earnings -- net .............................................................. 61,156,781 -------------- Net assets ..................................................................................... $ 162,039,468 ============== ==================================================================================================================================== Net Asset Value - ------------------------------------------------------------------------------------------------------------------------------------ Institutional -- Based on net assets of $4,354,390 and 334,489 shares outstanding .............. $ 13.02 ============== Investor A -- Based on net assets of $11,435,866 and 882,156 shares outstanding ................ $ 12.96 ============== Investor B -- Based on net assets of $88,103,549 and 6,932,169 shares outstanding .............. $ 12.71 ============== Investor C -- Based on net assets of $58,145,663 and 4,564,795 shares outstanding .............. $ 12.74 ============== * The cost and unrealized appreciation of investments as of October 31, 2007, as computed for federal income tax purposes, were as follows: Aggregate cost ........................................................................... $ 127,654,898 ============== Gross unrealized appreciation ............................................................ $ 34,687,848 Gross unrealized depreciation ............................................................ -- -------------- Net unrealized appreciation .............................................................. $ 34,687,848 ============== See Notes to Financial Statements.

See Notes to Financial Statements. BLACKROCK CORE PRINCIPAL PROTECTED FUND OCTOBER 31, 2007 11 Notes to Financial Statements BlackRock Core Principal Protected Fund 1. Significant Accounting Policies: BlackRock Core Principal Protected Fund (the "Fund") is a series of BlackRock 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 Master Large Cap Core Portfolio (the "Portfolio"), which is a series of Master Large Cap Series LLC (the "Master LLC"). Effective June 15, 2007, the Master LLC was converted from a Delaware statutory trust to a Delaware limited liability company. 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, 2007 was 2.9%. 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. Institutional Shares are sold only to certain eligible investors. Investor A Shares are sold with a front-end sales charge. Shares of Investor B and Investor 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 Investor A, Investor B and Investor C Shares bear certain expenses related to the shareholder servicing of such shares, and Investor B and Investor 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 shareholder servicing and distribution expenditures (except that Investor B shareholders may vote on material changes to the Investor A distribution plan). Income, expenses (other than expenses attributable to a specific class) and realized and unrealized gains and losses 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. (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. The counterparty for certain instruments may pledge cash or securities as collateral. o Financial futures contracts -- The Fund may purchase or sell financial futures contracts and options on such financial futures contracts. Financial 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. 12 BLACKROCK CORE PRINCIPAL PROTECTED FUND OCTOBER 31, 2007 Notes to Financial Statements (continued) BlackRock Core Principal Protected Fund (f) Dividends and distributions -- Dividends and distributions paid by the Fund are recorded on the ex-dividend dates. (g) Recent accounting pronouncements -- In July 2006, the Financial Accounting Standards Board ("FASB") issued Interpretation No. 48 ("FIN 48"), "Accounting for Uncertainty in Income Taxes -- an interpretation of FASB Statement No. 109." FIN 48 prescribes the minimum recognition threshold a tax position must meet in connection with accounting for uncertainties in income tax positions taken or expected to be taken by an entity, including mutual funds, before being measured and recognized in the financial statements. Adoption of FIN 48 is required for the last net asset value calculation in the first required financial statement reporting period for fiscal years beginning after December 15, 2006. The impact on the Fund's financial statements, if any, is currently being assessed. In September 2006, Statement of Financial Accounting Standards No. 157, "Fair Value Measurements" ("FAS 157"), was issued and is effective for fiscal years beginning after November 15, 2007. FAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. At this time, management is evaluating the implications of FAS 157 and its impact on the Fund's financial statements, if any, has not been determined. In addition, in February 2007, Statement of Financial Accounting Standards No. 159, "The Fair Value Option for Financial Assets and Financial Liabilities" ("FAS 159"), was issued and is effective for fiscal years beginning after November 15, 2007. Early adoption is permitted as of the beginning of a fiscal year that begins on or before November 15, 2007, provided the entity also elects to apply the provisions of FAS 157. FAS 159 permits entities to choose to measure many financial instruments and certain other items at fair value that are not currently required to be measured at fair value. FAS 159 also establishes presentation and disclosure requirements designed to facilitate comparisons between entities that choose different measurement attributes for similar types of assets and liabilities. At this time, management is evaluating the implications of FAS 159 and its impact on the Fund's financial statements, if any, has not been determined. (h) Reclassification -- 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, $2,344,585 has been reclassified between undistributed net realized capital gains and accumulated net investment loss as a result of permanent differences attributable to net operating losses. This reclassification has no effect on net assets or net asset values per share. 2. Investment Advisory Agreements and Transactions with Affiliates: The Trust, on behalf of the Fund, entered into an Investment Advisory Agreement with BlackRock Advisors, LLC (the "Manager"). The Trust has also entered into separate Distribution Agreements and Distribution Plans with FAM Distributors, Inc. ("FAMD") and BlackRock Distributors, Inc. ("BDI") (collectively, "the Distributor"). FAMD is a wholly owned subsidiary of Merrill Lynch Group, Inc. and BDI is an affiliate of BlackRock, Inc. Merrill Lynch and Co., Inc. ("Merrill Lynch") and The PNC Financial Services Group, Inc. ("PNC") are the principal owners of BlackRock, Inc. The Manager 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. The Manager has contractually agreed to waive its management fee by the amount of management fees the Fund pays the Manager indirectly through its investment in the Portfolio. For the year ended October 31, 2007, the Manager earned fees of $1,303,316, of which $802,151 was waived. In addition, the Manager 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 service fees) will not exceed 1.99%. This arrangement has a one-year term and is renewable. In addition, the Manager has entered into a sub-advisory agreement with BlackRock Investment Management, LLC ("BIM"), an affiliate of the Manager, under which the Manager pays the sub-adviser for services it provides a monthly fee at an annual rate that is a percentage of the management fee paid by the Fund to the Manager. 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 service 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: - -------------------------------------------------------------------------------- Service Distribution Fee Fee - -------------------------------------------------------------------------------- Investor A ................................... .25% -- Investor B ................................... .25% .75% Investor C ................................... .25% .75% - -------------------------------------------------------------------------------- Pursuant to sub-agreements with each Distributor, broker-dealers, including Merrill Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S"), a wholly owned subsidiary of Merrill Lynch, and each Distributor provide shareholder servicing and distribution services to the Fund. The ongoing service fee compensates the Distributor and each broker-dealer (including MLPF&S) for providing shareholder servicing to Investor A, Investor B and Investor C shareholders. The ongoing distribution fee compensates the Distributor and the broker-dealers for providing shareholder and distribution-related services to Investor B and Investor C shareholders. For the year ended October 31, 2007, affiliates received contingent deferred sales charges of $246,219 and $115 relating to transactions in Investor B and Investor C Shares, respectively. BLACKROCK CORE PRINCIPAL PROTECTED FUND OCTOBER 31, 2007 13 Notes to Financial Statements (continued) BlackRock Core Principal Protected Fund The Manager maintains a call center, which is responsible for providing certain shareholder services to the Fund, such as responding to shareholder inquiries and processing transactions based upon instructions from shareholders with respect to the subscription and redemption of Fund shares. During the year ended October 31, 2007, the following amounts have been accrued by the Fund to reimburse the Manager for costs incurred running the call center, which are a component of the transfer agent fees in the accompanying Statement of Operations. - -------------------------------------------------------------------------------- Call Center Fees - -------------------------------------------------------------------------------- Institutional .................................................. $ 55 Investor A ..................................................... $ 135 Investor B ..................................................... $1,173 Investor C ..................................................... $ 748 - -------------------------------------------------------------------------------- The Trust, on behalf of the Fund, and the Manager have entered into a Financial Guarantee Agreement with Ambac Assurance Corporation ("Ambac"). The Financial Guarantee Agreement is intended to make sure that on the Guaranteed 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 Guarantee 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 Guarantee 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 Guaranteed 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. PFPC Inc., an indirect, wholly owned subsidiary of PNC and an affiliate of the Manager, is the Fund's transfer agent. For the year ended October 31, 2007, the Fund reimbursed the Manager $3,168 for certain accounting services. Certain officers and/or trustees of the Fund are officers and/or directors of BlackRock, Inc. or its affiliates. 3. Beneficial Interest Transactions: Net decrease in net assets derived from beneficial interest transactions was $26,933,904 and $33,246,056 for the years ended October 31, 2007 and October 31, 2006, respectively.

Report of Independent Registered Public Accounting Firm BlackRock Core Principal Protected Fund To the Shareholders and Board of Trustees of BlackRock Principal Protected Trust: We have audited the accompanying statement of assets and liabilities of BlackRock Core Principal Protected Fund, one of the series constituting BlackRock Principal Protected Trust (the "Trust"), as of October 31, 2007, and 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). 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 BlackRock Core Principal Protected Fund of BlackRock Principal Protected Trust as of October 31, 2007, 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 accounting principles generally accepted in the United States of America.

Significant Accounting Policies: Master Large Cap Core Portfolio (the "Portfolio") is a series of Master Large Cap Series LLC (the "Master LLC"). The Master LLC is registered under the Investment Company Act of 1940, as amended, and is organized as a Delaware limited liability company. Prior to June 15, 2007, the Master LLC was organized as a Delaware statutory trust (the "Trust"). The Limited Liability Company Agreement (the "LLC Agreement") permits the Directors (and prior to June 15, 2007, the Declaration of Trust permitted the Trustees) to issue nontransferable interests in the Master LLC/Trust, subject to certain limitations. Throughout this report the Trust and the Master LLC are referred to as the Master LLC and the Board of Directors of the Master LLC and the Board of Trustees of the Trust are referred to as the Board of Directors. 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 held by the Portfolio that are traded on stock exchanges or the NASDAQ Global 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 Directors of the Master LLC. Long positions traded in the over-the-counter ("OTC") market, NASDAQ Capital Market 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 Directors of the Master LLC. 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. Effective September 4, 2007, exchange-traded options are valued at the mean between the last bid and ask prices at the close of the options market in which the options trade and previously were valued at the last sales price as of the close of options trading on applicable exchanges. Options traded in the OTC market are valued at the last asked price (options written) or the last bid price (options purchased). 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. Valuation of short-term investment vehicles is generally based on the net asset value of the underlying investment vehicle or amortized cost. 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 Directors of the Master LLC, 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 Master LLC under the general supervision of the Board of Directors of the Master LLC. Such valuations and procedures will be reviewed periodically by the Board of Directors of the Master LLC. 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 will generally be determined as of 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 will be valued at their fair value as determined in good faith by the Board of Directors of the Master LLC or by BlackRock Advisors, LLC (the "Manager"), an indirect, wholly owned subsidiary of BlackRock, Inc., using a pricing service and/or procedures approved by the Board of Directors of the Master LLC. (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. The counterparty for certain instruments may pledge cash or securities as collateral. o Financial futures contracts -- The Portfolio may purchase or sell financial futures contracts and options on such financial futures contracts. Financial futures contracts are contracts for delayed delivery of securities at a specific future date and at a specific price or yield. Upon entering into a contract, the Portfolio deposits, and maintains as collateral, such initial margin as required by the exchange on which the transaction is effected. Pursuant to the contract, the Portfolio agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in value of the contract. Such receipts or payments are known as variation margin and are recorded by the Portfolio as unrealized gains or losses. When the contract is closed, the Portfolio records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. o Options -- The Portfolio may purchase and write call and put options. When the Portfolio writes an option, an amount equal to the premium received by the Portfolio is reflected as an asset and an equivalent BLACKROCK CORE PRINCIPAL PROTECTED FUND OCTOBER 31, 2007 25 Notes to Financial Statements (continued) Master Large Cap Core Portfolio 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. 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) Bank overdraft -- The Portfolio recorded a bank overdraft, which resulted from management estimates of available cash. (g) Recent accounting pronouncements -- In July 2006, the Financial Accounting Standards Board ("FASB") issued Interpretation No. 48 ("FIN 48"), "Accounting for Uncertainty in Income Taxes -- an interpretation of FASB Statement No. 109." FIN 48 prescribes the minimum recognition threshold a tax position must meet in connection with accounting for uncertainties in income tax positions taken or expected to be taken by an entity, including mutual funds, before being measured and recognized in the financial statements. Adoption of FIN 48 is required for the last net asset value calculation in the first required financial statement reporting period for fiscal years beginning after December 15, 2006. The impact on the Portfolio's financial statements, if any, is currently being assessed. In September 2006, Statement of Financial Accounting Standards No. 157, "Fair Value Measurements" ("FAS 157"), was issued and is effective for fiscal years beginning after November 15, 2007. FAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. At this time, management is evaluating the implications of FAS 157 and its impact on the Portfolio's financial statements, if any, has not been determined. In addition, in February 2007, Statement of Financial Accounting Standards No. 159, "The Fair Value Option for Financial Assets and Financial Liabilities" ("FAS 159"), was issued and is effective for fiscal years beginning after November 15, 2007. Early adoption is permitted as of the beginning of a fiscal year that begins on or before November 15, 2007, provided the entity also elects to apply the provisions of FAS 157. FAS 159 permits entities to choose to measure many financial instruments and certain other items at fair value that are not currently required to be measured at fair value. FAS 159 also establishes presentation and disclosure requirements designed to facilitate comparisons between entities that choose different measurement attributes for similar types of assets and liabilities. At this time, management is evaluating the implications of FAS 159 and its impact on the Portfolio's financial statements, if any, has not been determined. 2. Investment Advisory Agreement and Transactions with Affiliates: The Master LLC, on behalf of the Portfolio, entered into an Investment Advisory Agreement with the Manager. Merrill Lynch and Co., Inc. ("Merrill Lynch") and The PNC Financial Services Group, Inc. ("PNC") are the principal owners of BlackRock, Inc. The Manager 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 26 BLACKROCK CORE PRINCIPAL PROTECTED FUND OCTOBER 31, 2007 Notes to Financial Statements (concluded) Master Large Cap Core Portfolio 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; .45% of average daily net assets in excess of $1 billion but not exceeding $5 billion and .40% of average daily net assets in excess of $5 billion. In addition, the Manager has entered into a sub-advisory agreement with BlackRock Investment Management, LLC ("BIM"), an affiliate of the Manager, under which the Manager pays the sub-adviser for services it provides a monthly fee at an annual rate that is a percentage of the management fee paid by the Portfolio to the Manager. 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 wholly owned subsidiary of Merrill Lynch, or its affiliates. As of October 31, 2007, the Portfolio lent securities with a value of $176,250,285 to MLPF&S or its affiliates. Pursuant to that order, the Portfolio has retained BIM as the securities lending agent for a fee based on a share of the returns on investment of cash collateral. BIM 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 the Manager or in registered money market funds advised by the Manager or its affiliates. For the year ended October 31, 2007, BIM received $464,185 in securities lending agent fees. In addition, MLPF&S received $100 in commissions on the execution of portfolio security transactions for the Portfolio for the year ended October 31, 2007. For the year ended October 31, 2007, the Portfolio reimbursed the Manager $224 for certain accounting services. Certain officers and/or directors of the Master LLC are officers and/or directors of BlackRock, Inc. or its affiliates. 3. Investments: Purchases and sales of investments, excluding short-term securities, for the year ended October 31, 2007 were $4,306,839,166 and $4,216,123,520, respectively. 4. Short-Term Borrowings: The Portfolio, along with certain other funds managed by the Manager and its affiliates, is party to a $500,000,000 credit agreement with a group of lenders, which expires November 2007 and was subsequently renewed. 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 .06% per annum based on the Portfolio's pro rata share of the unused portion of the credit agreement. Amounts borrowed under the credit agreement bear interest at a rate equal to, at each fund's election, the federal funds rate plus .35% 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, 2007. 5. Acquisitions: On September 24, 2007, an investor of the Portfolio acquired all of the net assets of BlackRock Investment Trust Portfolio of BlackRock Funds ("Investment Trust"), pursuant to a plan of reorganization. As a result of the reorganization, which included $286,539,853 of net unrealized appreciation, the Portfolio received an in-kind contribution of portfolio securities. BLACKROCK CORE PRINCIPAL PROTECTED FUND OCTOBER 31, 2007 27 Report of Independent Registered Public Accounting Firm Master Large Cap Core Portfolio To the Investors and Board of Directors of Master Large Cap Series LLC: 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 LLC (formerly Master Large Cap Series Trust) (the "Master LLC"), as of October 31, 2007, 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 Master LLC'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 Master LLC 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 Master LLC'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, 2007, 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 LLC as of October 31, 2007, 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 accounting principles generally accepted in the United States of America.

Robards qualify as financial experts pursuant to Item 3(c)(4) of Form N-CSR. Mr. Beim has a thorough understanding of generally accepted accounting principles, financial statements and internal control over financial reporting as well as audit committee functions. For 25 years, Mr. Beim was an investment banker actively engaged in financial analysis for securities transactions and mergers. These transactions presented a breadth and level of complexity of accounting issues that are generally comparable to the breadth and complexity of issues that can reasonably be expected to be raised by the registrant's financial statements. Mr. Beim has also been a professor of finance and economics at the Columbia University Graduate School of Business since 1991. Prof. Kester has a thorough understanding of generally accepted accounting principles, financial statements and internal control over financial reporting as well as audit committee functions. Prof. Kester has been involved in providing valuation and other financial consulting services to corporate clients since 1978. Prof. Kester's financial consulting services present a breadth and level of complexity of accounting issues that are generally comparable to the breadth and complexity of issues that can reasonably be expected to be raised by the registrant's financial statements. Ms. Robards has a thorough understanding of generally accepted accounting principles, financial statements and internal control over financial reporting as well as audit committee functions. Ms. Robards has been President of Robards & Company, a financial advisory firm, since 1987.

Ms. Robards has over 30 years of experience analyzing financial statements. She also is the member of the Audit Committees of one publicly held company and a non-profit organization. Under applicable securities laws, a person determined to be an audit committee financial expert will not be deemed an "expert" for any purpose, including without limitation for the purposes of Section 11 of the Securities Act of 1933, as a result of being designated or identified as an audit committee financial expert. The designation or identification as an audit committee financial expert does not impose on such person any duties, obligations, or liabilities greater than the duties, obligations, and liabilities imposed on such person as a member of the audit committee and board of directors in the absence of such designation or identification.

(e)(1) Audit Committee Pre-Approval Policies and Procedures: The registrant's audit committee (the "Committee") has adopted policies and procedures with regard to the pre-approval of services. 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. (e)(2) None of the services described in each of Items 4(b) through (d) were approved by the audit committee pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

Regulation S-X Rule 2-01(c)(7)(ii) - $284,500, 0% Item 5 - Audit Committee of Listed Registrants - Not Applicable Item 6 - Schedule of Investments - The registrant's Schedule of Investments is included as part of the Report to Stockholders filed under Item 1 of this form.
