OCTOBER 31, 2006 A Letter to Shareholders Dear Shareholder Ten months into 2006, we are able to say it has been an interesting year for investors. After a volatile start and far-reaching mid-year correction, the financial markets regained some positive momentum through late summer and fall. For the six- and 12-month periods ended October 31, 2006, most major market indexes managed to post positive returns: Total Returns as of October 31, 2006 6-month 12-month ====================================================================================== U.S. equities (Standard & Poor's 500 Index) +6.11% +16.34% - -------------------------------------------------------------------------------------- Small cap U.S. equities (Russell 2000 Index) +0.90 +19.98 - -------------------------------------------------------------------------------------- International equities (MSCI Europe, Australasia, Far East Index) +3.77 +27.52 - -------------------------------------------------------------------------------------- Fixed income (Lehman Brothers Aggregate Bond Index) +4.60 + 5.19 - -------------------------------------------------------------------------------------- Tax-exempt fixed income (Lehman Brothers Municipal Bond Index) +4.12 + 5.75 - -------------------------------------------------------------------------------------- High yield bonds (Credit Suisse High Yield Index) +4.66 +10.29 - -------------------------------------------------------------------------------------- The Federal Reserve Board (the Fed), after raising the target short-term interest rate 17 times between June 2004 and June 2006, finally opted to pause on August 8, 2006. This left the federal funds rate at 5.25%, where it remained through the September and October Fed meetings. In interrupting its two-year rate-hiking campaign, the Fed acknowledged that economic growth is slowing, led by softness in the housing market. However, the central bankers continue to take a cautionary position on inflation, despite a decline in energy prices in recent months. At the time of this writing, the price of oil had settled into the $60-per-barrel range after reaching nearly $78 per barrel earlier in the year. Notwithstanding the mid-year correction, equity markets generally found support in solid corporate earnings reports in the first three quarters of the year. Overall corporate health, including strong company balance sheets, helped to sustain robust dividend-distribution, share-buyback and merger-and-acquisition activity. Many international equity markets fared equally well or better, thanks in part to higher economic growth rates and low inflation. In the U.S. bond market, prices declined for much of the year as investors focused on decent economic activity and inflation concerns. Bond prices began to improve in late June as the economy showed signs of weakening and inflation pressures subsided. Notably, the Treasury curve inverted periodically, a phenomenon typically associated with periods of economic weakness. At the end of October, the one-month Treasury bill offered the highest yield on the curve at 5.18%, while the 30-year Treasury bond had a yield of 4.72%. Amid the uncertainty inherent in the financial markets, we encourage you to review your goals periodically with your financial professional and to make portfolio changes, as needed. For additional insight and timely "food for thought" for investors, we also invite you to visit Shareholder magazine at www.blackrock.com/shareholdermagazine. We are pleased to make our investor-friendly magazine available to you online. We thank you for trusting BlackRock with your investment assets, and we look forward to continuing to serve your investment needs. Sincerely, /s/ Robert C. Doll, Jr. Robert C. Doll, Jr. President and Director/Trustee BLACKROCK LARGE CAP SERIES FUNDS, INC. OCTOBER 31, 2006 3 A Discussion With Your Funds' Portfolio Manager Our quantitative and fundamental stock-selection process led the Funds to strong absolute and relative performance, as we continued to refine the portfolios throughout the year, looking for stocks that best met our investment criteria and pruning those that deteriorated. How did the BlackRock Large Cap Series Funds, Inc. perform during the fiscal year in light of the existing market conditions? For the 12-month period ended October 31, 2006, BlackRock Large Cap Core Fund of BlackRock Large Cap Series Funds, Inc.'s (formerly Merrill Lynch Large Cap Core Fund of Merrill Lynch Large Cap Series Funds, Inc.) Institutional, Investor A, Investor B, Investor C and Class R Shares had total returns of +16.91%, +16.61%, +15.72%, +15.64% and +16.29%, respectively, competitive with the +16.02% return of the benchmark Russell 1000 Index and ahead of the +14.50% average return of its comparable Lipper category of Multi-Cap Core Funds.* BlackRock Large Cap Growth Fund of BlackRock Large Cap Series Funds, Inc.'s (formerly Merrill Lynch Large Cap Growth Fund of Merrill Lynch Large Cap Series Funds, Inc.) Institutional, Service, Investor A, Investor B, Investor C and Class R Shares had total returns of +13.57%, +13.20%, +13.23%, +12.36%, +12.37% and +13.00%, respectively, exceeding the +10.84% return of the benchmark Russell 1000 Growth Index and the +10.39% average return of its comparable Lipper category of Multi-Cap Growth Funds.* BlackRock Large Cap Value Fund of BlackRock Large Cap Series Funds, Inc.'s (formerly Merrill Lynch Large Cap Value Fund of Merrill Lynch Large Cap Series Funds, Inc.) Institutional, Service, Investor A, Investor B, Investor C and Class R Shares had total returns of +18.06%, +17.73%, +17.78%, +16.81%, +16.89% and +17.41%, respectively, lagging the +21.46% return of its benchmark, the Russell 1000 Value Index, and pacing the +17.77% average return of the Lipper Multi-Cap Value Funds category for the 12-month period.* (Fund results shown do not reflect sales charges and would be lower if sales charges were included. Complete performance information for each Fund can be found on pages 6 - 10 of this report to shareholders.) Because the Funds invest in large-capitalization stocks that represent a significant part of the U.S. stock market, their portfolios were influenced by the same economic and market events that affected the broader stock market during the past 12 months. After a marked and far-reaching mid-year correction that spanned all sectors, styles and market-capitalization ranges, U.S. equities rallied to record highs, with the Dow Jones Industrial Average soaring above 12,150 in late October. Overall performance was positive for large cap stocks as they outperformed their small- to mid-sized counterparts 50% of the time, with value outperforming growth the majority of the time. During the latter months of the reporting period, the majority of corporate earnings reports were positive, with most companies meeting or exceeding expectations. The Federal Reserve Board (the Fed), under the leadership of new chairman Dr. Ben Bernanke, finally opted to interrupt its interest rate-hiking campaign on August 8, and remained at a pause in September and October. This came after 17 consecutive interest rate increases over two years. The price of crude oil escalated to a summer peak near $78 a barrel, then stabilized toward the end of the reporting period and stayed below $60 per barrel. The moderation in oil prices came in response to rising U.S. oil inventories and a quiet hurricane season. However, the elevated energy prices throughout the year had a negative impact on consumer spending. A retreating consumer, coupled with a slowdown in the residential housing sector, adversely affected gross domestic product (GDP), which was estimated at 1.6% for the third quarter of 2006, compared to a growth rate of 2.6% in the second quarter and 5.6% in the first quarter. What factors most influenced Fund performance during the fiscal year? In the case of BlackRock Large Cap Core Fund and BlackRock Large Cap Growth Fund, stock selection drove performance results, particularly within the industrials (airlines, machinery and aerospace & defense), materials (metals & mining) and information technology sectors (computer peripherals, communication equipment and software). For BlackRock Large Cap Value Fund, the positive performance generated by stock selection in industrials (machinery and aerospace & defense) and consumer discretionary was not enough to offset disappointing results from the combination of asset allocation and stock selection within energy, financials and health care. * Lipper Multi-Cap funds invest in a variety of market capitalization ranges without concentrating 75% of their equity assets in any one market-capitalization range over an extended period of time. Multi-Cap Core funds typically have an average price-to-earnings ratio, price-to-book ratio and three-year sales-per-share growth value compared to the S&P SuperComposite 1500 Index. Multi-Cap Growth funds typically have an above-average price-to-earnings ratio, price-to-book ratio and three-year sales-per-growth value compared to the S&P SuperComposite 1500 Index. Multi-Cap Value funds typically have a below-average price-to-earnings ratio, price-to-book ratio and three-year sales-per-growth value compared to the S&P SuperComposite 1500 Index. 4 BLACKROCK LARGE CAP SERIES FUNDS, INC. OCTOBER 31, 2006 At the individual stock level, the largest positive contributors to performance in BlackRock Large Cap Core Fund were NuCor Corp., BEA Systems, Inc., Kerr-McGee Corp., Qwest Communications International Inc. and AMR Corp. The largest detractors were Tellabs, Inc., McAfee, Inc., Valero Energy Corp., Pioneer Natural Resources Co. and Amgen, Inc. In BlackRock Large Cap Growth Fund, the largest positive contributors to performance were AMR Corp., NuCor, BEA Systems, Joy Global, Inc. and BMC Software, Inc., and the largest detractors were Advanced Micro Devices, Inc., ImClone Systems Inc., The Goodyear Tire & Rubber Co., Moody's Investors Service Inc. and Starbucks Corp. The largest contributors to the performance of BlackRock Large Cap Value Fund during the 12-month period were NuCor, Kerr-McGee, BEA Systems, Qwest Communications and CXS Corp., and the largest detractors were BellSouth Corp., AT&T, Inc., Goodyear Tire & Rubber, Valero Energy Corp. and Pioneer Natural Resources Co. As important as it is to hold stocks that performed well, it is equally important that we were able to avoid those that did not perform well. Examples of stocks that were present and performed poorly in the benchmarks, but were absent from the portfolios, included: Yahoo! Inc., The Home Depot, Inc., Medtronic, Inc. and Sprint Nextel Corporation for Large Cap Core; QUALCOMM Inc., Medtronic and Boston Scientific Corp. for BlackRock Large Cap Growth; and Sprint and Time Warner, Inc. for BlackRock Large Cap Value. What changes were made to the Funds' portfolios during the fiscal period? Overall, we continued to identify companies with favorable growth characteristics and earnings developments selling at attractive relative valuations. As a result of our bottom-up stock-selection process, we increased the portfolios' positions in industrials and reduced their exposure to the information technology, health care and energy sectors. In BlackRock Large Cap Core Fund, the largest purchases during the period were JPMorgan Chase & Co., Chevron Corp., Cisco Systems, Inc., AMR Corp. and Morgan Stanley. The largest sales were NVIDIA Corp., Amgen, Intel Corp., ConocoPhillips Co. and UnitedHealth Group Inc. In BlackRock Large Cap Growth Fund, the largest purchases were Cisco Systems, Inc., Oracle Corp., Hewlett-Packard Co., Nordstrom, Inc. and CA, Inc., and the largest sales were Intel Corp., Best Buy, Amgen, Staples, Inc. and UnitedHealth Group. In BlackRock Large Cap Value Fund, the largest purchases were Citigroup, Inc., Exxon Mobil Corp., Chevron Corp., JPMorgan Chase & Co. and Morgan Stanley. The largest sales were Valero Energy Corp., ConocoPhillips, Prudential Financial, Inc., Kerr-McGee and Atmel Corp. These transactions reflect our ongoing refinement of the portfolios, as we continue to look for stocks that best meet our investment criteria and prune those that have deteriorated versus our original assessment. How would you characterize the Funds' positioning at the close of the period? As of October 31, 2006, relative to their respective benchmarks, the Funds' largest overweights were in consumer discretionary, energy, information technology, industrials and health care. The largest underweights were in financials, consumer staples, utilities and telecommunication services. We believe the U.S. economy is headed for a housing- and consumer-led mid-cycle slowdown that will reduce inflation pressures, encourage the Fed to cut interest rates next year, and ultimately should allow equity prices to move higher. Concerns about inflation are starting to give way to concerns about weak economic growth. Fears about a hard economic landing are likely to intensify in the months ahead as the housing downturn feeds into a further consumer retrenchment. Nonetheless, we do not believe a recession is at hand given that the Fed has gone on hold without imposing a painful monetary squeeze. In our opinion, corporate earnings growth in 2007 is likely to be lower than in 2006. Currently, we are expecting growth levels to be around the 5% mark for next year. At present, our view is that the stock market may be slightly overbought, and the correction that occurred at the middle of this year may have a bit further to run as earnings estimates come down, concerns about inflation continue and the impact of the November elections unwinds. Equity markets have had a tremendous rally over the past three months, and we would view potentially softer markets as a digestion of these gains rather than as the start of any significant decline.

OCTOBER 31, 2006 5 Performance Data About Fund Performance Effective October 2, 2006, the Funds' Class A, Class B, Class C and Class I Shares were redesignated Investor A, Investor B, Investor C and Institutional Shares, respectively. Class R Shares did not change their designation. As previously communicated to shareholders, new sales charge schedules came into effect at the same time for certain of these classes. Each Fund has multiple classes of shares: o Institutional Shares are not subject to any front-end sales charge. 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% (but no distribution fee) and are available only to eligible investors. Service Shares performance results are those of Institutional Shares adjusted to reflect the service (12b-1) fees applicable to Service Shares. Service Shares commenced operations on October 2, 2006. Service Shares are offered only by BlackRock Large Cap Growth Fund and BlackRock Large Cap Value Fund. 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. These shares automatically convert to Investor A Shares after approximately eight years. (There is no initial sales charge for automatic share conversions.) All returns for periods greater than eight years reflect this conversion. o Investor C 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 for Class R Share fees. None of the past results shown should be considered a representation of future performance. Current performance may be lower or higher than the performance data quoted. Refer to www.blackrock.com to obtain performance data current to the most recent month-end. Performance results do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. Figures shown in each of the following tables assume reinvestment of all dividends and capital gain distributions, if any, at net asset value on the ex-dividend date. 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. 6 BLACKROCK LARGE CAP SERIES FUNDS, INC.

OCTOBER 31, 2006 Disclosure of Expenses 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 following example (which is based on a hypothetical investment of $1,000 invested on May 1, 2006 and held through October 31, 2006) is 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 first table below provides information about actual account values and actual expenses. In order to estimate the expenses a shareholder paid during the period covered by this report, shareholders can divide their account value by $1,000 and then multiply the result by the number in the first line under the heading entitled "Expenses Paid During the Period." The second table below provides information about hypothetical account values and hypothetical expenses based on each 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 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 table are intended to highlight shareholders' ongoing costs only and do not reflect any transactional expenses, such as sales charges, redemption fees or exchange fees. Therefore, the second table is useful in comparing ongoing expenses only, and will not help shareholders determine the relative total expenses of owning different funds. If these transactional expenses were included, shareholder expenses would have been higher.

OCTOBER 31, 2006 29 Notes to Financial Statements BlackRock Large Cap Series Funds, Inc. 1. Significant Accounting Policies: On September 29, 2006, Merrill Lynch Large Cap Core Fund, Merrill Lynch Large Cap Growth Fund and Merrill Lynch Large Cap Value Fund, constituting Merrill Lynch Large Cap Series Funds, Inc., were renamed BlackRock Large Cap Core Fund, BlackRock Large Cap Growth Fund and BlackRock Large Cap Value Fund (the "Funds" or individually as the "Fund") and BlackRock Large Cap Series Funds, Inc., respectively. The Funds 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, their 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, constituting Master Large Cap Series Trust, 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. On October 31, 2006, the percentage of Master S&P 500 Index Series (the "Series") owned by BlackRock Large Cap Core Fund was 0.6% and 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 95.2%, 100% and 98.1%, respectively. The Funds offer multiple classes of shares. Effective October 2, 2006, Class I, Class A, Class B and Class C Shares were redesignated Institutional, Investor A, Investor B and Investor C Shares, respectively. Additionally, Service Shares commenced operations. Class R Shares did not change their designation. Service and 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. 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 account maintenance 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 account maintenance 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 Portfolio 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 fiscal years beginning after December 15, 2006. The impact on the Funds' financial statements, if any, is currently being assessed. In addition, in September 2006, Statement of Financial Accounting Standards No. 157, "Fair Value Measurements" 30 BLACKROCK LARGE CAP SERIES FUNDS, INC. OCTOBER 31, 2006 Notes to Financial Statements (continued) BlackRock Large Cap Series Funds, Inc. ("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. Management is currently evaluating the implication of FAS 157. At this time its impact on the Funds' financial statements 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, $11,220,386 has been reclassified between paid-in capital in excess of par and accumulated net investment loss, and $1,945,911 has been reclassified between paid-in capital in excess of par and accumulated net realized capital losses allocated from the Portfolios as a result of permanent differences attributable to net operating losses, limitation of various capital loss carryforwards and other permanent differences. These reclassifications have 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, $4,681,453 has been reclassified between paid-in capital in excess of par and accumulated net investment loss, and $356,190,749 has been reclassified between paid-in capital in excess of par and accumulated net realized capital losses as a result of permanent differences attributable to net operating losses and the expiration of capital loss carryforwards. This reclassification has no effect on net assets or net asset values per share. BlackRock Large Cap Value 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, $3,327,782 has been reclassified between accumulated paid-in capital in excess of par and accumulated net investment loss as a result of permanent differences attributable to net operating loss. This reclassification has no effect on net assets or net asset values per share. 2. Transactions with Affiliates: On September 29, 2006, BlackRock, Inc. and Merrill Lynch & Co., Inc. ("Merrill Lynch") combined Merrill Lynch's investment management business, Merrill Lynch Investment Managers, L.P. ("MLIM") and its affiliates, including Fund Asset Management, L.P. ("FAM"), with BlackRock, Inc. to create a new independent company. Merrill Lynch has a 49.8% economic interest and a 45% voting interest in the combined company and The PNC Financial Services Group, Inc. ("PNC"), has approximately a 34% economic and voting interest. The new company operates under the BlackRock name and is governed by a board of directors with a majority of independent members. On August 15, 2006 and August 31, 2006, shareholders of each Fund approved a new Investment Advisory Agreement for each Portfolio with BlackRock Advisors, Inc. (the "Manager"), an indirect, wholly owned subsidiary of BlackRock, Inc. BlackRock Advisors, Inc. was recently reorganized into a limited liability company and renamed BlackRock Advisors, LLC. The new Investment Advisory Agreement became effective on September 29, 2006. Prior to September 29, 2006, FAM was the Investment Adviser. The general partner of FAM is Princeton Services, Inc. ("PSI"), an indirect, wholly owned subsidiary of Merrill Lynch, which is the limited partner. Each Fund has entered into an Administration Agreement with BlackRock Advisors, LLC. 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. Prior to September 29, 2006, FAM acted as each Fund's Administrator and was compensated at the same fee rate. The Fund has also entered into a separate Distribution Agreement and Distribution Plan 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. 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 account maintenance ("service fees") 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 BLACKROCK LARGE CAP SERIES FUNDS, INC.

Incorporated ("MLPF&S"), a wholly owned subsidiary of Merrill Lynch, and an affiliate of each of the Distributors, also provides account maintenance and distribution services to the Funds. The ongoing service fee compensates the Distributors and each broker-dealer (including MLPF&S) for providing account maintenance services to Service, Investor A, Investor B, Investor C and Class R shareholders. The ongoing distribution fee compensates the Distributors and the broker-dealers for providing shareholder and distribution-related services to Investor B, Investor C and Class R shareholders.

OCTOBER 31, 2006 37 Report of Independent Registered Public Accounting Firm BlackRock Large Cap Series Funds, Inc. To the Shareholders and Board of Directors of BlackRock Large Cap Series Funds, Inc.: We have audited the accompanying statements of assets and liabilities of BlackRock Large Cap Series Funds, Inc. (the "Fund"), comprising BlackRock Large Cap Core Fund, BlackRock Large Cap Growth Fund and BlackRock Large Cap Value Fund (formerly Merrill Lynch Large Cap Series Funds, Inc., comprising Merrill Lynch Large Cap Core Fund, Merrill Lynch Large Cap Growth Fund and Merrill Lynch Large Cap Value Fund), respectively, as of October 31, 2006, and 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 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 each of the funds constituting BlackRock Large Cap Series Funds, Inc. as of October 31, 2006, 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 U.S. generally accepted accounting principles.

OCTOBER 31, 2006 55 Notes to Financial Statements Master Large Cap Series Trust 1. Significant Accounting Policies: Master Large Cap Core Portfolio, Master Large Cap Growth Portfolio and Master Large Cap Value Portfolio (the "Portfolios" or individually as the "Portfolio") constitute the Master Large Cap Series Trust (the "Trust"). The Trust is registered under the Investment Company Act of 1940, as amended, and is organized as a Delaware statutory trust. The Declaration of Trust permits the Trustees to issue nontransferable interests in the Portfolio, subject to certain limitations. The 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 Portfolio. (a) Valuation of investments -- Equity securities held by each Portfolio that are traded on stock exchanges or the Nasdaq National Market are valued at the last sale price or official close price on the exchange, as of the close of business on the day the securities are being valued or, lacking any sales, at the last available bid price for long positions, and at the last available asked price for short positions. In cases where equity securities are traded on more than one exchange, the securities are valued on the exchange designated as the primary market by or under the authority of the Board of Trustees of the Trust. Long positions traded in the over-the-counter ("OTC") markets, Nasdaq Small Cap or Bulletin Board are valued at the last available bid price or yield equivalent obtained from one or more dealers or pricing services approved by the Board of Trustees of the Trust. Short positions traded in the OTC 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. Options written or purchased are valued at the last sales price in the case of exchange-traded options. 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. Obligations with remaining maturities of 60 days or less are valued at amortized cost unless the Manager believes that this method no longer produces fair valuations. Valuation of other 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 Trustees of the Trust, 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 Trust under the general supervision of the Trust's Board of Trustees. Such valuations and procedures will be reviewed periodically by the Board of Trustees of the Trust. Generally, trading in foreign securities, as well as U.S. government securities, 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 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 may be valued at their fair value as determined in good faith by the Trust's Board of Trustees or by the Manager using a pricing service and/or procedures approved by the Trust's Board of Trustees. (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. 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 56 BLACKROCK LARGE CAP SERIES FUNDS, INC. OCTOBER 31, 2006 Notes to Financial Statements (continued) Master Large Cap Series Trust 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 -- 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 The Portfolio recorded a bank overdraft, which resulted from management estimates of available cash. Master Large Cap Growth Portfolio The Portfolio recorded a bank overdraft, which resulted from an unprojected payment of net investment income dividends. Master Large Cap Value Portfolio The Portfolio recorded a bank overdraft, which resulted from a failed trade that settled the next day. (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 BLACKROCK LARGE CAP SERIES FUNDS, INC. OCTOBER 31, 2006 57 Notes to Financial Statements (continued) Master Large Cap Series Trust FIN 48 is required for fiscal years beginning after December 15, 2006. The impact on the Portfolios' financial statements, if any, is currently being assessed. In addition, 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. Management is currently evaluating the implication of FAS 157. At this time its impact on the Portfolios' financial statements has not been determined. 2. Investment Advisory Agreement and Transactions with Affiliates: On September 29, 2006, BlackRock, Inc. and Merrill Lynch & Co., Inc. ("Merrill Lynch") combined Merrill Lynch's investment management business, Merrill Lynch Investment Managers, L.P. ("MLIM") and its affiliates, including Fund Asset Management, L.P. ("FAM"), with BlackRock, Inc. to create a new independent company. Merrill Lynch has a 49.8% economic interest and a 45% voting interest in the combined company and The PNC Financial Services Group, Inc. ("PNC"), has approximately a 34% economic and voting interest. The new company operates under the BlackRock name and is governed by a board of directors with a majority of independent members. The shareholders of each of the investors of the Trust approved on August 15, 2006 and August 31, 2006 a new Investment Advisory Agreement with BlackRock Advisors, Inc. (the "Manager"), an indirect, wholly owned subsidiary of BlackRock, Inc. BlackRock Advisors, Inc. was recently reorganized into a limited liability company and renamed BlackRock Advisors, LLC. The new Investment Advisory Agreement between the Trust, on behalf of each Portfolio, and the Manager became effective on September 29, 2006. Prior to September 29, 2006, FAM was the Investment Adviser. The general partner of FAM is Princeton Services, Inc. ("PSI"), an indirect, wholly owned subsidiary of Merrill Lynch, which is the limited partner. The Manager is responsible for the management of each Portfolio's investments and provides the necessary personnel, facilities, equipment and certain other services necessary to the operations of the Portfolio. Prior to May 9, 2006, for such services the Master Large Cap Core Portfolio pays a monthly fee at an annual rate of .50% of the average daily value of the Portfolio's net assets not exceeding $1 billion and .45% of average daily net assets in excess of $1 billion. Master Large Cap Growth Portfolio and Master Large Cap Value Portfolio each pay a monthly fee at an annual rate of .50% of the average daily value of the Portfolio's net assets. Effective May 9, 2006, FAM had voluntarily agreed and on September 29, 2006 the Manager contractually agreed to implement an additional breakpoint for a portion of its investment advisory fee. For such services, Master Large Cap Core Portfolio pays a monthly fee at an annual rate of .50% of the average daily 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; Master Large Cap Growth Portfolio pays a monthly fee at an annual rate of .50% of the average daily net assets not exceeding $5 billion and .45% of average daily net assets in excess of $5 billion; and Master Large Cap Value Portfolio pays a monthly fee at an annual rate of .50% of the average daily net assets not exceeding $3 billion and .45% of average daily net assets in excess of $3 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 to each Portfolio a fee equal to 74% of the management fee paid by each of the Portfolios to the Manager. Prior to September 29, 2006, FAM had a Sub-Advisory Agreement with Merrill Lynch Asset Management U.K. Limited ("MLAM U.K."), an affiliate of FAM. 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"), an affiliate of the Manager, or its affiliates. As of October 31, 2006, Master Large Cap Core Portfolio, Master Large Cap Growth Portfolio and Master Large Cap Value Portfolio lent securities with values of $257,949,987, $11,124,429 and $215,775,285, respectively, to MLPF&S 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. Prior to September 29, 2006, BIM was organized as Merrill Lynch Investment Managers, LLC ("MLIM, LLC"), an affiliate of FAM, and MLIM, LLC was the security 58 BLACKROCK LARGE CAP SERIES FUNDS, INC. OCTOBER 31, 2006 Notes to Financial Statements (concluded) Master Large Cap Series Trust lending agent. 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. For the year ended October 31, 2006, BIM received $197,604, $31,324 and $143,732 in securities lending agent fees for Master Large Cap Core Portfolio, Master Large Cap Growth Portfolio and Master Large Cap Value Portfolio, respectively.

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.

BLACKROCK LARGE CAP SERIES FUNDS, INC. OCTOBER 31, 2006 59 Report of Independent Registered Public Accounting Firm Master Large Cap Series Trust To the Investors and Board of Trustees of Master Large Cap Series Trust: We have audited the accompanying statements of assets and liabilities, including the schedules of investments of Master Large Cap Series Trust (the "Trust"), comprising Master Large Cap Core Portfolio, Master Large Cap Growth Portfolio and Master Large Cap Value Portfolio, as of October 31, 2006, 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 Trust's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Trust is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Trust's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of October 31, 2006, 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 each of the portfolios constituting Master Large Cap Series Trust, as of October 31, 2006, 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 U.S. generally accepted accounting principles. Deloitte & Touche LLP Princeton, New Jersey December 21, 2006 60 BLACKROCK LARGE CAP SERIES FUNDS, INC. OCTOBER 31, 2006 Disclosure of Investment Advisory Agreement Disclosure of FAM Management Agreement The Board of Trustees of Master Large Cap Series Trust (the "Trust") met in June 2006 to consider approval of the investment advisory agreement between the Trust, on behalf of each Portfolio, and Fund Asset Management, L.P. ("FAM"), the Trust's investment adviser at that time, and the sub- advisory agreement on behalf of the Trust between FAM and Merrill Lynch Asset Management U.K. Limited, an affiliate. The Board of Directors of BlackRock Large Cap Series Funds, Inc. (the "Series Funds"), each series of which (each, a "Fund") invests all its assets in the corresponding Portfolio of the Trust, also considered approval of the Trust's investment advisory agreement and the sub-advisory agreement. Activities and Composition of the Board All but one member of the Boards is an independent director/trustee whose only affiliation with FAM or other Merrill Lynch affiliates was as a director/trustee of the Trust and the Funds and as a director or trustee of certain other funds advised by FAM or its affiliates. The Co-chairmen of each Board are also independent directors/trustees. New director/trustee nominees are chosen by a Nominating Committee comprised of independent directors/trustees. All independent directors/trustees also are members of each Board's Audit Committee, and the independent directors/trustees meet in executive session at each in-person Board meeting. Each Board and each Board's Audit Committee meet in person for at least two days each quarter and conduct other in-person and telephone meetings throughout the year, some of which are formal Board meetings and some of which are informational meetings. The independent counsel to the independent directors/trustees attends all in-person Board and Audit Committee meetings and other meetings at the independent directors/trustees' request. FAM Investment Advisory Agreement -- Matters Considered by the Boards Every year, the Boards consider approval of the Trust's investment advisory agreement and any sub-advisory agreement. The Boards assesses the nature, scope and quality of the services provided to the Trust and the Funds by the personnel of the investment adviser, the sub-adviser and their affiliates, including administrative services, shareholder services, oversight of fund accounting, marketing services and assistance in meeting legal and regulatory requirements. The Boards also receive and assess information regarding the services provided to the Trust and the Funds by certain unaffiliated service providers. At various times throughout the year, the Boards also consider a range of information in connection with their oversight of the services provided by the investment adviser and its affiliates, including the sub-adviser. Among the matters considered are: (a) fees (in addition to management fees) paid to the investment adviser and its affiliates by the Trust and/or the Funds/Portfolios, such as transfer agency fees and fees for marketing and distribution; (b) Trust and Fund/Portfolio operating expenses paid to third parties; (c) the resources devoted to and compliance reports relating to each Fund's/Portfolio's investment objective, policies and restrictions, and the Trust's and the Series Funds' compliance with their Code of Ethics and compliance policies and procedures; and (d) the nature, cost and character of non-investment management services provided by the investment adviser and its affiliates. The Boards noted their view of FAM as one of the most experienced global asset management firms and considered the overall services provided by FAM to be of high quality. The Boards also noted their view of FAM as financially sound and well managed and noted FAM's affiliation with one of America's largest financial firms. The Boards work closely with the investment adviser in overseeing the investment adviser's efforts to achieve good performance. As part of this effort, the Boards discuss portfolio manager effectiveness and, when performance is not satisfactory, discuss with the investment adviser taking steps such as changing investment personnel. Annual Consideration of Approval by the Boards In the period prior to the Board meeting to consider renewal of the investment advisory agreement and any sub-advisory agreement, the Boards request and receive materials specifically relating to the investment advisory agreement and/or sub-advisory agreement. These materials are prepared separately with respect to each Fund/Portfolio and include (a) information compiled by Lipper Inc. ("Lipper") on the fees and expenses and the investment performance of the Fund/Portfolio as compared to a comparable group of funds as classified by Lipper; (b) sales and redemption data for the Fund; (c) a discussion by the Fund's/Portfolio's portfolio management team regarding investment strategies used by the Fund/Portfolio during its most recent fiscal year; (d) information on the profitability to the investment adviser and its affiliates of the investment advisory agreement, the sub-advisory agreement and other relationships with the Fund/Portfolio; and (e) information provided by the investment adviser concerning investment advisory fees charged to other clients, such as retail funds, under similar investment mandates. Since the sub-advisory services were provided by an affiliate BLACKROCK LARGE CAP SERIES FUNDS, INC. OCTOBER 31, 2006 61 Disclosure of Investment Advisory Agreement (concluded) of FAM and no additional fee is paid for these services, the Boards considered the existing sub-advisory agreement and the investment advisory agreement between the Trust and FAM (the "FAM Investment Advisory Agreement") together. The Boards also consider other matters they deem important to the approval process, such as payments made to the investment adviser or its affiliates relating to the distribution of Fund shares, services related to the valuation and pricing of Fund/Portfolio portfolio holdings, allocation of Fund/Portfolio brokerage fees (including the related benefits to the Investment Adviser of "soft dollars"), the Fund's/Portfolio's portfolio turnover statistics, and direct and indirect benefits to the investment adviser, the sub-adviser and their affiliates from their relationship with the Series Funds and the Trust. Certain Specific Renewal Data In connection with the most recent renewal of the FAM Investment Advisory Agreement and the sub-advisory agreement in June 2006, the independent directors'/trustees' and the Boards' review included the following: Services Provided by the Investment Adviser -- The Boards reviewed the nature, extent and quality of services provided by FAM and the sub-adviser, focusing on the investment advisory services and the resulting performance of each Fund/Portfolio. The Boards use data provided by Lipper and by management in its review of advisory services. The Boards compared each Fund's/Portfolio's performance -- both including and excluding the effects of the Fund's/Portfolio's fees and expenses -- to the performance of a comparable group of funds and the performance of a relevant index or combination of indexes. While the Boards review performance data at least quarterly, the Boards attach more importance to performance over relatively long periods of time, typically three to five years. The Boards concluded that the comparative data indicated that each Fund's/Portfolio's performance was competitive. Considering all these factors, each Board concluded that the nature and quality of the services provided supported the continuation of the FAM Investment Advisory Agreement. FAM's Personnel and Investment Process -- The Boards reviewed each Fund's/Portfolio's investment objectives and strategies. The Boards discussed with FAM's senior management responsible for investment operations and the senior management of FAM's equity investing group the strategies being used to achieve the stated objectives. Among other things, the Boards considered the size, education and experience of FAM's investment staff, its use of technology, and FAM's approach to training and retaining portfolio managers and other research, advisory and management personnel. The Boards also reviewed FAM's compensation policies and practices with respect to each Fund's/Portfolio's portfolio managers. The Boards also considered the experience of each Fund's/Portfolio's portfolio manager and noted that Mr. Doll (the Senior Portfolio Manager for each Fund/Portfolio) has over 20 years experience in portfolio management. The Boards concluded that FAM and its investment staff have extensive experience in analyzing and managing the types of investments used by the Funds/Portfolios and that each Fund/Portfolio benefits from that experience. Management Fees and Other Expenses -- The Boards review each Fund's/Portfolio's contractual management fee rate and actual management fee rate as a percentage of total assets at common asset levels -- the actual rate includes advisory and administrative service fees and the effects of any fee waivers -- compared to the other funds in its Lipper category and compare the Fund's total expenses to those of other comparable funds. The Boards considered the services provided to and the fees charged by FAM to other clients with similar investment mandates. The Boards determined that each Fund's contractual and actual management fee rates, as well as total expenses, were competitive with those of comparable funds. The Boards concluded that each Fund's/Portfolio's management fee rate and overall expense ratio were reasonable. Profitability -- The Boards consider the cost of the services provided to the Series' Funds and the Trust by the investment adviser and the investment adviser's and its affiliates' profits relating to the management and distribution of the Series' Funds and the Trust and the funds advised by the investment adviser and its affiliates. As part of its analysis, the Boards reviewed FAM's methodology in allocating its costs to the management of each Fund/Portfolio and concluded that there was a reasonable basis for the allocation. The Boards concluded that the profits of FAM and its affiliates were acceptable in relation to the nature and quality of services provided. Economies of Scale -- The Boards considered the extent to which economies of scale might be realized as the assets of the Funds/Portfolio increase and whether there should be changes in the management fee rate or structure in order to enable the Funds and the Trust to participate in these economies of scale. The Boards noted that each Fund's/Portfolio's management fee schedule included either contractual or voluntary breakpoints that reduce the management fee as the Fund's/Portfolio's assets increase above certain levels. The 62 BLACKROCK LARGE CAP SERIES FUNDS, INC. OCTOBER 31, 2006 Boards determined that the management fee structure was reasonable and that no changes were currently necessary. Conclusion After the independent directors/trustees deliberated in executive session, the entire Board of the Series Funds and the entire Board of the Trust, including all of the independent directors/trustees, approved the renewal of the existing FAM Investment Advisory Agreement and sub-advisory agreement, concluding that the advisory fee was reasonable in relation to the services provided and that a contract renewal was in the best interests of shareholders. Disclosure of New Investment Advisory Agreement New BlackRock Investment Advisory Agreement -- Matters Considered by the Boards In connection with the combination of Merrill Lynch's investment advisory business, including Fund Asset Management, L.P. (the "Previous Investment Adviser"), with that of BlackRock, Inc. ("BlackRock") to create a new independent company ("New BlackRock") (the "Transaction"), the Board of Trustees of the Trust considered and approved a new investment advisory agreement (the "BlackRock Investment Advisory Agreement") between the Trust, on behalf of each Portfolio, and BlackRock Advisors, LLC ("BlackRock Advisors"). Because each Fund is a feeder fund that invests all of its assets in the corresponding Portfolio, the Board of Directors of the Series Funds also considered the BlackRock Investment Advisory Agreement. Each Fund's shareholders subsequently approved the BlackRock Investment Advisory Agreement and it became effective on September 29, 2006, replacing the Trust's investment advisory agreement with the Previous Investment Adviser (the "Previous Investment Advisory Agreement"). The Boards discussed the BlackRock Investment Advisory Agreement at telephonic and in-person meetings held during April and May 2006. The Boards, including the independent directors/trustees, approved the BlackRock Investment Advisory Agreement at an in-person meeting held on May 9, 2006. To assist the Boards in their consideration of the BlackRock Investment Advisory Agreement, BlackRock provided materials and information about BlackRock, including its financial condition and asset management capabilities and organization, and Merrill Lynch provided materials and information about the Transaction. Each Board's independent directors/ trustees, through their independent legal counsel, also requested and received additional information from Merrill Lynch and BlackRock in connection with their consideration of the BlackRock Investment Advisory Agreement. The additional information was provided in advance of the May 9, 2006 meetings. In addition, the independent directors/ trustees consulted with their counsel and Fund/Trust counsel on numerous occasions, discussing, among other things, the legal standards and certain other considerations relevant to the directors'/trustees' deliberations. At the Board meetings, the directors/trustees discussed with Merrill Lynch management and certain BlackRock representatives the Transaction, its strategic rationale and BlackRock's general plans and intentions regarding the Funds and the Trust. At these Board meetings, representatives of Merrill Lynch and BlackRock made presentations to and responded to questions from the Boards. The directors/trustees also inquired about the plans for and anticipated roles and responsibilities of certain employees and officers of the Previous Investment Adviser, and of its affiliates, to be transferred to BlackRock in connection with the Transaction. The independent directors/ trustees also conferred separately and with their counsel about the Transaction and other matters related to the Transaction on a number of occasions, including in connection with the April and May 2006 meetings. Among the matters discussed were proposed reorganizations in which BlackRock Large Cap Growth Fund would acquire the assets and liabilities of BlackRock Large Cap Growth Equity Portfolio, a portfolio of BlackRock Funds, and BlackRock Large Cap Value Fund would acquire the assets and liabilities of BlackRock Value Equity Portfolio, also a portfolio of BlackRock Funds. After the presentations and after reviewing the written materials provided, the independent directors/trustees met in executive sessions with their counsel to consider the BlackRock Investment Advisory Agreement. In connection with the directors'/trustees' review of the BlackRock Investment Advisory Agreement, Merrill Lynch BLACKROCK LARGE CAP SERIES FUNDS, INC. OCTOBER 31, 2006 63 Disclosure of New Investment Advisory Agreement (continued) and/or BlackRock advised the directors/trustees about a variety of matters. The advice included the following, among other matters: o that there was not expected to be any diminution in the nature, quality and extent of services provided to the Trust, the Series Funds or Fund shareholders by BlackRock Advisors, including compliance services; o that operation of New BlackRock as an independent investment management firm would enhance its ability to attract and retain talented professionals; o that the Trust and the Series Funds were expected to benefit from having access to BlackRock's state of the art technology and risk management analytic tools, including investment tools, provided under the BlackRock Solutions(R) brand name; o that BlackRock had no present intention to alter any applicable expense waivers or reimbursements that were currently in effect and, while it reserved the right to do so in the future, it would seek Board approval before making any changes; o that in connection with the Transaction, Merrill Lynch and BlackRock had agreed to conduct, and use reasonable best efforts to cause their respective affiliates to conduct, their respective businesses in compliance with the conditions of Section 15(f) of the Investment Company Act of 1940 (the "1940 Act") in relation to any public funds advised by BlackRock or the Previous Investment Adviser (or affiliates), respectively; and o that Merrill Lynch and BlackRock would derive benefits from the Transaction and that, as a result, they had a financial interest in the matters being considered that was different from that of Fund shareholders. The directors/trustees considered the information provided by Merrill Lynch and BlackRock above, and, among other factors, the following: o the potential benefits to Fund shareholders from being part of a combined fund family with BlackRock-sponsored funds, including possible economies of scale and access to investment opportunities; o the reputation, financial strength and resources of BlackRock and its investment advisory subsidiaries and the anticipated financial strength and resources of New BlackRock; o the compliance policies and procedures of BlackRock Advisors; o the terms and conditions of the BlackRock Investment Advisory Agreement, including the fact that no Fund's/ Portfolio's schedule of total advisory fees would increase under the BlackRock Investment Advisory Agreement, but would remain the same or, because breakpoints were added to the advisory fee schedules, the average fee rates of each Fund/Portfolio would be lower if the Fund/Portfolio grows in size; o that in May 2005, the Boards had performed a full annual review of the Previous Investment Advisory Agreement, as required by the 1940 Act, and had determined that the Previous Investment Adviser had the capabilities, resources and personnel necessary to provide the advisory and administrative services that were then being provided to the Trust and the Series Funds; and that the advisory and/or management fees paid by the Funds/ Portfolios, taking into account any applicable agreed-upon fee waivers and breakpoints, had represented reasonable compensation to the Previous Investment Adviser in light of the services provided, the costs to the Previous Investment Adviser of providing those services, economies of scale, the fees and other expenses paid by similar funds (including information provided by Lipper Inc. ["Lipper"]), and such other matters as the directors/trustees had considered relevant in the exercise of their reasonable judgment; and o that Merrill Lynch had agreed to pay all expenses of the Trust and the Series Funds in connection with the consideration by the Boards of the BlackRock Investment Advisory Agreement and related agreements and all costs of shareholder approval of the BlackRock Investment Advisory Agreement and as a result the Trust and the Series Funds would bear no costs in obtaining shareholder approval of the BlackRock Investment Advisory Agreement. Certain of these considerations are discussed in more detail below. In its review of the BlackRock Investment Advisory Agreement, the Boards assessed the nature, quality and scope of the services to be provided to the Trust and the Series Funds by the personnel of BlackRock Advisors and its affiliates, including administrative services, shareholder services, oversight of fund accounting and assistance in meeting legal and regulatory requirements. In their review of the BlackRock Investment Advisory Agreement, the Boards also considered 64 BLACKROCK LARGE CAP SERIES FUNDS, INC. OCTOBER 31, 2006 a range of information in connection with their oversight of the services to be provided by BlackRock Advisors and its affiliates. Among the matters considered for the Trust and the Series Fund were: (a) fees (in addition to management fees) to be paid to BlackRock Advisors and its affiliates by the Trust and the Series Funds; (b) Trust and Fund operating expenses paid to third parties; (c) the resources devoted to and compliance reports relating to the Funds'/Portfolios' investment objective, policies and restrictions, and the compliance of the Trust and the Series Funds with their Code of Ethics and BlackRock Advisors' compliance policies and procedures; and (d) the nature, cost and character of non-investment management services to be provided by BlackRock Advisors and its affiliates. In the period prior to the Board meeting to consider renewal of the Previous Investment Advisory Agreement, the Boards had requested and received materials specifically relating to the Previous Investment Advisory Agreement. For each Fund/Portfolio, these materials included (a) information compiled by Lipper on the fees and expenses and the investment performance of the Fund/Portfolio as compared to a comparable group of funds as classified by Lipper; (b) a discussion by the Fund's/Portfolio's portfolio management team on investment strategies used by the Fund/Portfolio during its most recent fiscal year; (c) information on the profitability to the Previous Investment Adviser of the Previous Investment Advisory Agreement and other payments received by the Previous Investment Adviser and its affiliates from the Fund/Portfolio; and (d) information provided by the Previous Investment Adviser concerning services related to the valuation and pricing of Fund/Portfolio portfolio holdings, the Fund's/Portfolio's portfolio turnover statistics, and direct and indirect benefits to the Previous Investment Adviser and its affiliates from their relationship with the Fund/Portfolio. In their deliberations, the directors/trustees considered information received in connection with their most recent approval of the continuance of the Previous Investment Advisory Agreement, in addition to information provided by BlackRock and BlackRock Advisors in connection with their evaluation of the terms and conditions of the BlackRock Investment Advisory Agreement. The directors/trustees did not identify any particular information that was all-important or controlling. The Boards, including a majority of the independent directors/trustees, concluded that the terms of the BlackRock Investment Advisory Agreement are appropriate, that the fees to be paid are reasonable in light of the services to be provided to the Trust and the Series Funds, and that the BlackRock Investment Advisory Agreement should be approved and recommended to Fund shareholders. Nature, Quality and Extent of Services Provided -- The Boards reviewed the nature, quality and scope of services provided by the Previous Investment Adviser, including the investment advisory services and the resulting performance of the Fund/Portfolio, as well as the nature, quality and extent of services expected to be provided by BlackRock Advisors. The Boards focused primarily on the Previous Investment Adviser's investment advisory services and each Fund's/Portfolio's investment performance, but also considered certain areas in which both the Previous Investment Adviser and the Trust and the Series Funds received services as part of the Merrill Lynch complex. The Boards compared each Fund's/Portfolio's performance -- both including and excluding the effects of fees and expenses -- to the performance of a comparable group of mutual funds, and the performance of a relevant index or combination of indexes. While the Board reviews performance data at least quarterly, consistent with the Previous Investment Adviser's investment goals, the Boards attach more importance to performance over relatively long periods of time, typically three to five years. In evaluating the nature, quality and extent of the services to be provided by BlackRock Advisors under the BlackRock Investment Advisory Agreement, the directors/trustees considered, among other things, the expected impact of the Transaction on the operations, facilities, organization and personnel of New BlackRock and how it would affect the Trust and the Series Funds; the ability of BlackRock Advisors to perform its duties after the Transaction; and any anticipated changes to the investment and other practices of the Trust and the Series Funds. The directors/trustees considered the fact that, as part of a reorganization, it was being proposed that BlackRock Large Cap Growth Fund acquire the assets and liabilities of BlackRock Large Cap Growth Equity Portfolio, a portfolio of BlackRock Funds, and that BlackRock Large Cap Value Fund acquire the assets and liabilities of BlackRock Large Cap Value Equity Portfolio, also a portfolio of BlackRock Funds. The directors/trustees were given information with respect to the potential benefits to the Trust, the Series Funds and Fund shareholders from having access to BlackRock's state of the art technology and risk management analytic tools, including the investment tools provided under the BlackRock Solutions brand name. BLACKROCK LARGE CAP SERIES FUNDS, INC. OCTOBER 31, 2006 65 Disclosure of New Investment Advisory Agreement (continued) The directors/trustees were advised that, as a result of Merrill Lynch's equity interest in BlackRock after the Transaction, the Funds/Portfolios would continue to be subject to restrictions concerning certain transactions involving Merrill Lynch affiliates (for example, transactions with a Merrill Lynch broker-dealer acting as principal) absent revised or new regulatory relief. The directors/trustees were advised that a revision of existing regulatory relief with respect to these restrictions was being sought from the Securities and Exchange Commission and were advised of the possibility of the receipt of such revised regulatory relief. Based on their review of the materials provided and the assurances they had received from the management of Merrill Lynch and of BlackRock, the directors/trustees determined that the nature and quality of services to be provided to the Trust and the Series Funds under the BlackRock Investment Advisory Agreement were expected to be as good as or better than that provided under the Previous Investment Advisory Agreement. The directors/trustees were advised that BlackRock Advisors did not plan to change any of the Funds'/Portfolios' portfolio management team upon the closing of the transaction. It was noted, however, that other changes in personnel were expected to follow the Transaction and the combination of the operations of the Previous Investment Adviser and its affiliates with those of BlackRock. The directors/trustees noted that if current portfolio managers or other personnel were to cease to be available prior to the closing of the Transaction, the Boards would consider all available options, including seeking the investment advisory or other services of BlackRock affiliates. Accordingly, the directors/trustees concluded that, overall, they were satisfied with assurances from BlackRock and BlackRock Advisors as to the expected nature, quality and extent of the services to be provided to the Trust and the Series Funds under the BlackRock Investment Advisory Agreement. Costs of Services Provided, Fees and Profitability -- It was noted that, in conjunction with their recent review of the Previous Investment Advisory Agreement, the directors/trustees had received, among other things, a report from Lipper comparing each Fund's/Portfolio's fees and expenses to those of a peer group selected by Lipper, and information as to the fees charged by the Previous Investment Adviser or its affiliates to other registered investment company clients for investment management services. The Boards reviewed each Fund's/Portfolio's contractual management fee rate and actual management fee rate as a percentage of total assets at common asset levels -- the actual rate includes advisory and administrative service fees and the effects of any fee waivers -- compared to the other funds in its Lipper category. The Boards also compared each Fund's/Portfolio's total expenses to those of other comparable funds. The information showed that each Fund/Portfolio had fees and expenses within the range of fees and expenses of comparable funds. The Boards considered the services to be provided by and the fees to be charged by BlackRock Advisors to other funds with similar investment mandates and noted that the fees charged by BlackRock Advisors in those cases, including fee waivers and expense reimbursements, were generally comparable to those being charged to the Funds/Portfolios. The Boards also noted that, as a general matter, according to the information provided by BlackRock, fees charged to institutional clients were lower than the fees charged to the Funds/Portfolios, but BlackRock Advisors provided less extensive services to such clients. The Boards concluded that each Fund's/Portfolio's management fee and fee rate and overall expense ratio are reasonable compared to those of other comparable funds. In evaluating the costs of the services to be provided by BlackRock Advisors under the BlackRock Investment Advisory Agreement, the directors/trustees considered, among other things, whether advisory and administrative fees or other expenses would change as a result of the Transaction. The Board of the Series Funds noted that in addition to the BlackRock Investment Advisory Agreement, it was considering, on behalf of the Series Funds and each Fund, a new administration agreement with BlackRock Advisors as administrator to replace the Series Funds' administration agreement under which the Previous Investment Adviser was serving as administrator. Based on their review of the materials provided and the fact that the BlackRock Investment Advisory Agreement and the new administration agreement are substantially similar to the corresponding previous agreements in all material respects, including the rate of compensation, the Boards determined that the Transaction should not increase the total fees payable, including any fee waivers or after any expense caps or expense reimbursements, for advisory and administrative services. The directors/trustees noted that it was not possible to predict how the Transaction would affect BlackRock Advisors' profitability from its relationship with the Trust and the Series Funds. The directors/trustees discussed with BlackRock Advisors its general methodology to be used in determining its profitability with respect to its relationship with the Trust and the Series Funds and noted that they expect to receive profitability information from BlackRock Advisors on at least an annual basis. 66 BLACKROCK LARGE CAP SERIES FUNDS, INC. OCTOBER 31, 2006 Economies of Scale -- The Boards considered the extent to which economies of scale might be realized as the assets of the Funds/Portfolios increase and whether there should be changes in the management fee rate or structure in order to enable the Funds/Portfolios to participate in these economies of scale. Breakpoints were added to each Fund's/Portfolio's fee schedule that would have the effect of lowering each Fund's average fee rates if the Fund grows in size. Otherwise, the Boards determined that changes were not currently necessary and that the Funds/Portfolios appropriately participated in these economies of scale. Fall-Out Benefits -- The directors/trustees considered whether the Funds/Portfolios would generate any fall-out benefits to BlackRock Advisors. Fall-out benefits are indirect profits from other activities that accrue to a fund's investment adviser or its affiliates solely because of the existence of the fund. In evaluating the fall-out benefits to be received by BlackRock Advisors under the BlackRock Investment Advisory Agreement, the directors/trustees considered whether BlackRock Advisors would experience such benefits to the same extent that the Previous Investment Adviser was experiencing such benefits under the Previous Investment Advisory Agreement. Based on their review of the materials provided, including materials received in connection with their most recent approval of the continuance of the Previous Investment Advisory Agreement, and their discussions with management of the Previous Investment Adviser and BlackRock, the directors/trustees determined that BlackRock Advisors' fall-out benefits could include increased ability for BlackRock to distribute shares of its funds and other investment products and to obtain research services using the Funds'/Portfolios' portfolio transaction brokerage commissions. The directors/trustees noted that any fall-out benefits were difficult to quantify with certainty. Investment Performance -- The directors/trustees considered investment performance for each Fund/Portfolio. The directors/trustees compared each Fund's/Portfolio's performance -- both including and excluding the effects of fees and expenses -- to the performance of a comparable group of funds, and the performance of a relevant index or combination of indexes. The comparative information received from Lipper showed each Fund's/Portfolio's performance at various levels within the range of performance of comparable funds over different time periods. The directors/trustees believed each Fund's/Portfolio's performance was satisfactory. Also, the Boards took into account the investment performance of funds advised by BlackRock Advisors. The Boards considered comparative information from Lipper which showed that the performance of the funds advised by BlackRock Advisors was within the range of performance of comparable funds over different time periods. The Boards noted BlackRock's considerable investment management experience and capabilities, but were unable to predict what effect, if any, consummation of the Transaction would have on the future performance of the Funds/Portfolios. Conclusion -- After the independent directors/trustees deliberated in executive session, the entire Board of the Trust and the entire Board of the Series Funds, including the independent directors/trustees, approved the BlackRock Investment Advisory Agreement, concluding that the advisory fee rate was reasonable in relation to the services provided and that the BlackRock Investment Advisory Agreement was in the best interests of the shareholders. In approving the BlackRock Investment Advisory Agreement, the Boards noted that they anticipated reviewing the continuance of the agreement in advance of the expiration of the initial two-year period. New BlackRock Sub-Advisory Agreement -- Matters Considered by the Boards At an in-person meeting held on August 22-23, 2006, the Board of the Trust and the Board of the Fund, including the independent directors/trustees, discussed and approved the sub-advisory agreement (the "BlackRock Sub-Advisory Agreement") between BlackRock Advisors and its affiliate, BlackRock Investment Management, LLC (the "Sub-Adviser"). The BlackRock Sub-Advisory Agreement became effective on September 29, 2006, at the same time the BlackRock Investment Advisory Agreement became effective. Pursuant to the BlackRock Sub-Advisory Agreement, the Sub-Adviser receives a monthly fee from BlackRock Advisors equal to 74% of the advisory fee received by BlackRock Advisors under the BlackRock Investment Advisory Agreement. BlackRock Advisors pays the Sub-Adviser out of its own resources, and there is no increase in the expenses of the Trust or the Funds as a result of the BlackRock Sub-Advisory Agreement. In approving the BlackRock Sub-Advisory Agreement at the August in-person meeting, the Boards reviewed their considerations in connection with their approval of the BlackRock Investment Advisory Agreement in May 2006. The Boards relied on the same information and considered the same factors as those discussed above in connection with the approval of the BlackRock Investment Advisory Agreement, and came to the same conclusions. In reviewing the sub-advisory fee BLACKROCK LARGE CAP SERIES FUNDS, INC. OCTOBER 31, 2006 67 Disclosure of New Investment Advisory Agreement (concluded) rate provided in the BlackRock Sub-Advisory Agreement, the Boards noted the fact that both BlackRock Advisors and the Sub-Adviser have significant responsibilities under their respective advisory agreements. BlackRock Advisors remains responsible for oversight of the Trust's and the Series Funds' operations and administration, and the Sub-Adviser provides advisory services to the Trust and is responsible for the day-to-day management of each Fund's/Portfolio's portfolio under the BlackRock Sub-Advisory Agreement. The Boards also took into account the fact that there is no increase in total advisory fees paid by any of the Funds/Portfolios as a result of the BlackRock Sub-Advisory Agreement. Under all of the circumstances, the Boards concluded that it was a reasonable allocation of fees for the Sub-Adviser to receive 74% of the advisory fee paid to BlackRock Advisors under the BlackRock Investment Advisory Agreement. After the independent directors/trustees deliberated in executive session, the entire Board of the Trust and the entire Board of the Series Fund, including the independent directors/ trustees, approved the BlackRock Sub-Advisory Agreement, concluding that the sub-advisory fee was reasonable in relation to the services provided and that the BlackRock Sub-Advisory Agreement was in the best interests of shareholders. 68 BLACKROCK LARGE CAP SERIES FUNDS, INC.

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.
