OCTOBER 31, 2007 A Letter to Shareholders Dear Shareholder The October reporting period was fairly tumultuous for financial markets, but culminated in positive performance for most major benchmarks: Total Returns as of October 31, 2007 6-month 12-month ================================================================================================================ U.S. equities (S&P 500 Index) +5.49% +14.56% - ---------------------------------------------------------------------------------------------------------------- Small cap U.S. equities (Russell 2000 Index) +2.25% + 9.27% - ---------------------------------------------------------------------------------------------------------------- International equities (MSCI Europe, Australasia, Far East Index) +8.19% +24.91% - ---------------------------------------------------------------------------------------------------------------- Fixed income (Lehman Brothers U.S. Aggregate Bond Index) +2.68% + 5.38% - ---------------------------------------------------------------------------------------------------------------- Tax-exempt fixed income (Lehman Brothers Municipal Bond Index) +1.30% + 2.91% - ---------------------------------------------------------------------------------------------------------------- High yield bonds (Lehman Brothers U.S. Corporate High Yield 2% Issuer Cap Index) -0.07% + 6.89% - ---------------------------------------------------------------------------------------------------------------- Past performance is no guarantee of future results. 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.

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 The Fund's favorable asset allocation decisions, through its investment in Master Large Cap Core Portfolio, 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 the industrials and materials sectors 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, Lexmark International, Inc., BEA Systems, Inc., 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, 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 and Goldman Sachs Group, Inc. Describe the Fund's positioning at period-end. o Relative to its benchmark, the Fund ended the 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. 4 BLACKROCK LARGE CAP SERIES FUNDS, INC.

OCTOBER 31, 2007 5 Fund Summary BlackRock Large Cap Growth Fund Portfolio Management Commentary How did the Fund perform? o The Fund generated strong absolute returns for the fiscal year, but modestly underperformed its benchmark, the Russell 1000 Growth Index. What factors influenced performance? o At a very high level, the Fund's favorable stock selection, through its investment in Master Large Cap Growth Portfolio, in health care and industrials provided the most significant positive contribution to performance. Disappointing stock selection in the information technology and consumer discretionary sectors accounted for the majority of the underperformance. o Stock selection and an underweighting of the consumer staples sector benefited performance. Stock selection also was strong in health care, where we took profits in service companies. We view these companies as trading vehicles given the countervailing influences of positive fundamentals and negative political pressures. Stock selection within the industrials sector, particularly among machinery companies, also enhanced Fund returns. The largest individual contributors to performance were Southern Copper Corp., Cisco Systems, Inc., Juniper Networks, Inc., Raytheon Co. and Biogen Idec, Inc. o Stock selection in the energy sector (particularly in oil equipment and services companies) and in the consumer discretionary sector (notably in specialty and multi-line retailers) detracted from results. The performance-enhancing overweight in information technology (IT) was offset by poor stock selection within the sector as semiconductors, IT services, software and computers & peripherals did not perform as anticipated. The largest individual detractors included RadioShack Corp., Compuware Corp., CH Richard Ellis Group, Inc., Convergys Corp. and Electronic Data Systems Corp. o Within information technology, we increased our weightings in companies with global exposure, where we believe there is significant upside potential. Within industrials and materials, we own a number of large, globally exposed companies benefiting from the commodity boom and general demand strength from both developing and emerging markets outside the United States. Describe recent portfolio activity. o Over the course of the year, we increased the Fund's exposure to health care and information technology. Among our largest purchases were CA Inc., UnitedHealth Group, Inc., Dell, Inc., Valero Energy Corp. and RadioShack Corp. o We reduced exposure to the consumer discretionary, industrials, financials and materials sectors. Our largest sales included Biogen Idec, Inc., Emdeon Corp., The Goldman Sachs Group, Inc., AMR Corp. and Continental Airlines, Inc. Describe the Fund's positioning at period-end. o Relative to its benchmark, the Fund ended the fiscal year overweight in information technology, consumer discretionary and materials, and underweight in consumer staples, financials and utilities. 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.

OCTOBER 31, 2007 7 Fund Summary BlackRock Large Cap Value Fund Portfolio Management Commentary How did the Fund perform? o The Fund delivered strong absolute performance for the fiscal year, outperforming its benchmark, the Russell 1000 Value Index. What factors influenced performance? o The Fund's outperformance is attributed to both asset allocation and stock selection decisions. The Fund benefited, through its investment in Master Large Cap Value Portfolio, from its underweight position in financials and overweight in industrials, and from good stock selection in financials, health care and industrials. o Within financials, the Fund is significantly underweight the benchmark, particularly in commercial banks, which have lagged recently. Stock selection among capital markets players and diversified financial services firms contributed positively. o Stock selection and an overweight position in the industrials sector enhanced performance, thanks primarily to stock selection in the aerospace & defense and machinery areas. Within health care, service providers and biotechnology contributed positively to performance. The largest individual contributors included Tesoro Corp., EMC Corp., SPX Corp., Biogen Idec, Inc. and Frontier Oil Corp. o Partially offsetting these positives was the combination of stock selection and an underweighting of the telecommunication services and utilities sectors. Stock selection was negative in consumer staples and information technology, and gains achieved from overweighting the energy sector were offset by poor stock performance. The biggest individual detractors included King Pharmaceuticals, Inc., ConocoPhillips, Lexmark International, Inc., BEA Systems, Inc. and Occidental Petroleum Corp. o Stock selection and an overweight position in consumer discretionary hindered the Fund's relative results. Given ongoing concerns about consumer spending, we shifted the cyclical bias of the portfolio away from the domestic consumer and toward more global, industrial-based companies. Describe recent portfolio activity. o Over the course of the year, we increased the Fund's exposure to health care, utilities and telecommunication services. Among our largest purchases were ConocoPhillips, American International Group, Inc., General Electric Co., Valero Energy Corp. and Deere & Co. o We reduced exposure to the consumer discretionary, financials, energy and consumer staples sectors. Our largest sales included Citigroup, Inc., Biogen Idec, Inc., Prudential Financials, Inc., Lehman Brothers Holdings, Inc. and Merck & Co., Inc. Describe the Fund's positioning at period-end. o Relative to its benchmark, the Fund ended the fiscal year overweight in information technology, health care, energy, industrials and materials, and underweight in financials, utilities, telecommunication services, consumer staples and consumer discretionary. 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.

Institutional Shares bear no ongoing distribution or service fees and are available only to eligible investors. o Service Shares are not subject to any sales charge. Service Shares are subject to a service fee of 0.25% per year (but no distribution fee) and are available only to eligible investors. For BlackRock Large Cap Growth Fund and BlackRock Large Cap Value Fund, prior to October 2, 2006, Service Share performance results are those of Institutional Shares (which have no distribution or service fees) restated to reflect the Service Share fees. For BlackRock Large Cap Core Fund, prior to September 24, 2007, Service Share performance results are those of Institutional Shares (which have no distribution or service fees) restated to reflect the Service Share fees. o Investor A Shares incur a maximum initial sales charge (front-end load) of 5.25% and a service fee of 0.25% per year (but no distribution fee). o Investor B Shares are subject to a maximum contingent deferred sales charge of 4.50% declining to 0% after six years. In addition, Investor B Shares are subject to a distribution fee of 0.75% per year and a service fee of 0.25% per year.

In addition, Investor C Shares are subject to a 1% contingent deferred sales charge if redeemed within one year of purchase. o Class R Shares do not incur a maximum initial sales charge (front-end load) or deferred sales charge. These shares are subject to a distribution fee of 0.25% per year and a service fee of 0.25% per year. Class R Shares are available only to certain retirement plans. Prior to inception, Class R Share performance results are those of Institutional Shares (which have no distribution or service fees) restated to reflect Class R Share fees. 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 each of the performance tables on page 11 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 BlackRock Large Cap Series Funds, Inc. Shareholders of these Funds 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 examples on page 11 (which are based on a hypothetical investment of $1,000 invested on May 1, 2007 and held through October 31, 2007) are intended to assist shareholders both in calculating expenses based on an investment in each Fund and in comparing these expenses with similar costs of investing in other mutual funds. The tables provide 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 Fund and share class under the heading entitled "Expenses Paid During the Period." The tables also provide information about hypothetical account values and hypothetical expenses based on the Funds' 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 these Funds 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 tables 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 tables are 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. 10 BLACKROCK LARGE CAP SERIES FUNDS, INC.

See Notes to Financial Statements. 28 BLACKROCK LARGE CAP SERIES FUNDS, INC. OCTOBER 31, 2007 Notes to Financial Statements BlackRock Large Cap Series Funds, Inc. 1. Significant Accounting Policies: BlackRock Large Cap Core Fund, BlackRock Large Cap Growth Fund and BlackRock Large Cap Value Fund (the "Funds" or individually as the "Fund"), constituting BlackRock Large Cap Series Funds, Inc., are registered under the Investment Company Act of 1940, as amended, as diversified, open-end investment companies. Each Fund seeks to achieve its investment objective by investing all, or a portion of, its assets in Master Large Cap Core Portfolio, Master Large Cap Growth Portfolio and Master Large Cap Value Portfolio (the "Portfolios" or individually as the "Portfolio"), respectively, of Master Large Cap Series LLC (the "Master LLC"), which have the same investment objective and strategies as the corresponding Funds. The value of the Funds' investment in the Portfolios reflects the Funds' proportionate interest in the net assets of the Portfolios. The performance of the Funds is directly affected by the performance of the Portfolios. The financial statements of the Portfolios, including the Schedules of Investments, are included elsewhere in this report and should be read in conjunction with the Funds' financial statements. The Funds' 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 percentages of Master Large Cap Core Portfolio, Master Large Cap Growth Portfolio and Master Large Cap Value Portfolio owned by BlackRock Large Cap Core Fund, BlackRock Large Cap Growth Fund and BlackRock Large Cap Value Fund were 97.1%, 96.4% and 98.5%, respectively. The Funds offer multiple classes of shares. Institutional and Service 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. Class R Shares are sold only to certain retirement plans. All classes of shares have identical voting, dividend, liquidation and other rights and the same terms and conditions, except that Service, Investor A, Investor B, Investor C and Class R Shares bear certain expenses related to the shareholder servicing of such shares, and Investor B, Investor C and Class R Shares also bear certain expenses related to the distribution of such shares. Each class has exclusive voting rights with respect to matters relating to its shareholder servicing and distribution expenditures (except that Investor B shareholders may vote on certain 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 Funds. (a) Valuation of investments -- Each Fund records its investment at fair value. Valuation of securities held by the Portfolios is discussed in Note 1(a) of the Portfolios' Notes to Financial Statements, which are included elsewhere in this report. (b) Investment income and expenses -- Each Fund records daily its proportionate share of the Portfolio's income, expenses and realized and unrealized gains and losses. In addition, each Fund accrues its own expenses. (c) Income taxes -- It is each Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its taxable income to shareholders. Therefore, no federal income tax provision is required. Under the applicable foreign tax law, withholding taxes may be imposed on interest, dividends and capital gains at various rates. (d) Prepaid registration fees -- Prepaid registration fees are charged to expense as the related shares are issued. (e) Dividends and distributions -- Dividends and distributions paid by each Fund are recorded on the ex-dividend dates. (f) Investment transactions -- Investment transactions in each Portfolio are accounted for on a trade date basis. (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 each 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 each 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 BLACKROCK LARGE CAP SERIES FUNDS, INC. OCTOBER 31, 2007 29 Notes to Financial Statements (continued) BlackRock Large Cap Series Funds, Inc. 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 each Fund's financial statements, if any, has not been determined. (h) Reclassifications -- BlackRock Large Cap Core Fund 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, $12,086,681 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 and classification of partnership income. This reclassification has no effect on net assets or net asset values per share. BlackRock Large Cap Growth Fund 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, $6,483,394 has been reclassified between paid-in capital in excess of par and accumulated net investment loss as a result of a permanent difference attributable to a net operating loss. This reclassification has no effect on net assets or net asset values per share. 2. Investment Advisory Agreement and Transactions with Affiliates: Each Fund has entered into an Administration Agreement with BlackRock Advisors, LLC (the "Manager"), an indirect, wholly owned subsidiary of BlackRock, Inc. Each Fund pays a monthly fee at an annual rate of .25% of the Fund's average daily net assets for the performance of administrative services (other than investment advice and related portfolio activities) necessary for the operation of the Fund. With respect to the BlackRock Large Cap Core Fund, effective September 24, 2007, the Manager has contractually agreed to waive the Fund's administration fee in the amount of the Fund's share of the administration fee paid by the Fund. For the period September 24, 2007 to October 31, 2007, the Manager earned fees of $1,487,784, of which $329,053 were waived. For the period September 24, 2007 to October 31, 2007, the Manager contractually agreed to waive and/or reimburse fees and/or expenses in order to limit expenses (excluding interest expense and certain other fund expenses) as a percentage of average daily net assets allocated to certain classes of the Fund as follows: 1.11% (for Investor A Shares), and 1.91% (for Investor B Shares). The Manager has agreed not to reduce or discontinue this contractual waiver or reimbursement until October 31, 2008, unless approved by the Board of Directors of the Fund, including a majority of the non-interested Directors. Each Fund has also entered into separate Distribution Agreements and Distribution Plans with FAM Distributors, Inc. ("FAMD") and BlackRock Distributors, Inc. and its affiliates ("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 & Co., Inc. ("Merrill Lynch") and The PNC Financial Services Group, Inc. ("PNC") are the principal owners of BlackRock, Inc. Pursuant to the Distribution Plans adopted by the Funds in accordance with Rule 12b-1 under the Investment Company Act of 1940, the Funds pay each 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 - -------------------------------------------------------------------------------- Service .............................................. .25% -- Investor A ........................................... .25% -- Investor B ........................................... .25% .75% Investor C ........................................... .25% .75% Class R .............................................. .25% .25% - -------------------------------------------------------------------------------- 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 provide shareholder servicing and distribution services to the Funds. The ongoing service fee compensates the Distributor and the broker-dealer (including MLPF&S) for providing shareholder servicing to Service, Investor A, Investor B, Investor C and Class R shareholders. The ongoing distribution fee compensates the Distributor and the broker-dealers for providing shareholder servicing and distribution-related services to Investor B, Investor C and Class R shareholders. For the year ended October 31, 2007, FAMD and BDI earned underwriting discounts and direct commissions and MLPF&S and BDI earned dealer concessions on sales of the Funds' Investor A Shares as follows: - -------------------------------------------------------------------------------- Investor A - -------------------------------------------------------------------------------- BlackRock Large Cap Core Fund .................................... $1,813,139 BlackRock Large Cap Growth Fund .................................. $ 350,936 BlackRock Large Cap Value Fund ................................... $ 739,097 - -------------------------------------------------------------------------------- For the year ended October 31, 2007, affiliates received contingent deferred sales charges relating to transactions in Investor B and Investor C Shares as follows: - -------------------------------------------------------------------------------- Investor B Investor C - -------------------------------------------------------------------------------- BlackRock Large Cap Core Fund ................ $315,074 $175,462 BlackRock Large Cap Growth Fund .............. $ 87,043 $ 28,676 BlackRock Large Cap Value Fund ............... $188,448 $133,293 - -------------------------------------------------------------------------------- 30 BLACKROCK LARGE CAP SERIES FUNDS, INC.

These financial statements and financial highlights are the responsibility of the Fund'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 Fund 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 Fund'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 Large Cap Core Fund, BlackRock Large Cap Growth Fund and BlackRock Large Cap Value Fund of BlackRock Large Cap Series Funds, Inc. as of October 31, 2007, the results of their operations for the year then ended, the changes in their net assets for each of the two years in the period then ended, and their 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.

OCTOBER 31, 2007 Notes to Financial Statements Master Large Cap Series LLC 1. Significant Accounting Policies: Master Large Cap Core Portfolio, Master Large Cap Growth Portfolio and Master Large Cap Value Portfolio (the "Portfolios" or individually the "Portfolio") constitute the 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 Portfolios' 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 Portfolios. (a) Valuation of investments -- Equity securities held by each 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") markets, 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 markets are valued at the last available asked price. Portfolio securities that are traded both in the OTC markets 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 price 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 Portfolios 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. Each 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 each 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 Master LLC's Board of Directors. Such valuations and procedures are reviewed periodically by the Board of Directors of the Master LLC. Generally, trading in foreign securities, as well as U.S. government securities, money market instruments, and certain fixed income securities, 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 each 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 each 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 Master LLC's Board of Directors 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 Master LLC's Board of Directors. (b) Derivative financial instruments -- Each 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 -- Each 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 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 BLACKROCK LARGE CAP SERIES FUNDS, INC. OCTOBER 31, 2007 55 Notes to Financial Statements (continued) Master Large Cap Series LLC 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 -- Each 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 -- Master Large Cap Core Portfolio and Master Large Cap Value Portfolio are classified as partnerships for federal income tax purposes. Master Large Cap Growth Portfolio is considered as a "pass-through" entity for federal income tax purposes. As such, each investor in the Portfolio is treated as owner of its proportionate share of the net assets, income, expenses and realized and unrealized gains and losses of the Portfolio. Therefore, no federal income tax provision is required. 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 -- Each Portfolio may lend securities to financial institutions that provide cash or securities issued or guaranteed by the U.S. government as collateral, which will be maintained at all times in an amount equal to at least 100% of the current market value of the loaned securities. The market value of the loaned securities is determined at the close of business of the Portfolio and any additional required collateral is delivered to the Portfolio on the next business day. Where the Portfolio receives securities as collateral for the loaned securities, it receives a fee from the borrower. The Portfolio typically receives the income on the loaned securities, but does not receive the income on the collateral. Where the Portfolio receives cash collateral, it may invest such collateral and retain the amount earned on such investment, net of any amount rebated to the borrower. Loans of securities are terminable at any time and the borrower, after notice, is required to return borrowed securities within five business days. The Portfolio may pay reasonable finders, 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 -- Master Large Cap Core Portfolio and Master Large Cap Value Portfolio each 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 Portfolios' 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 Portfolios' 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 Portfolios' financial statements, if any, has not been determined. 56 BLACKROCK LARGE CAP SERIES FUNDS, INC.

The Portfolios have 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.

Pursuant to that order, the Portfolios have 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 Portfolios, invest cash collateral received by the Portfolios 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.

Each 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.

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.

BLACKROCK LARGE CAP SERIES FUNDS, INC. OCTOBER 31, 2007 57 Report of Independent Registered Public Accounting Firm Master Large Cap Series LLC To the Investors and Board of Directors of Master Large Cap Series LLC: We have audited the accompanying statements of assets and liabilities, including the schedules of investments of Master Large Cap Series LLC (formerly Master Large Cap Series Trust) (the "Master LLC"), comprising Master Large Cap Core Portfolio, Master Large Cap Growth Portfolio and Master Large Cap Value Portfolio, as of October 31, 2007, the related statements 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, Master Large Cap Growth Portfolio and Master Large Cap Value Portfolio of Master Large Cap Series LLC, as of October 31, 2007, the results of their operations for the year then ended, the changes in their net assets for each of the two years in the period then ended, and their 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.

(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.
