APRIL 30, 2008 A Letter to Shareholders Dear Shareholder Over the past several months, financial markets have been buffeted by the housing recession, the credit market unraveling and related liquidity freeze and steadily rising commodity prices. Counterbalancing these difficulties were booming export activity, a robust non-financial corporate sector and, notably, aggressive and timely monetary and fiscal policy actions. Amid the market tumult, the Federal Reserve Board (the "Fed") intervened with a series of moves to bolster liquidity and ensure financial market stability. Since September 2007, the central bank slashed the target federal funds rate 325 basis points (3.25%), bringing the rate to 2.0% as of period-end. Of greater magnitude, however, were the Fed's other policy decisions, which included opening the discount window directly to broker dealers and investment banks and backstopping the unprecedented rescue of Bear Stearns. The Fed's response to the financial crisis helped to improve credit conditions and investor mood. After hitting a low point on March 17 (coinciding with the collapse of Bear Stearns), equity markets found a welcome respite in April, when the S&P 500 Index of U.S. stocks posted positive monthly performance for the first time since October 2007. International markets, which outpaced those of the U.S. for much of 2007, saw a reversal in that trend, as effects of the credit crisis and downward pressures on growth were far-reaching. In contrast to equity markets, Treasury securities rallied (yields fell as prices correspondingly rose), as a broad "flight-to-quality" theme persisted. The yield on 10-year Treasury issues, which touched 5.30% in June 2007 (its highest level in five years), fell to 4.04% by year-end and to 3.77% by April 30. Treasury issues relinquished some of their gains in April, however, as investor appetite for risk returned and other high-quality fixed income sectors outperformed. Problems within the monoline insurance industry and the failure of auctions for auction rate securities plagued the municipal bond market, driving yields higher and prices lower across the curve. However, in conjunction with the more recent shift in sentiment, the sector delivered strong performance in the final month of the reporting period. Overall, the major benchmark indexes generated results that generally reflected heightened investor risk aversion: Total Returns as of April 30, 2008 6-month 12-month ========================================================================================================================= U.S. equities (S&P 500 Index) - 9.64% - 4.68% - ------------------------------------------------------------------------------------------------------------------------- Small cap U.S. equities (Russell 2000 Index) -12.92 -10.96 - ------------------------------------------------------------------------------------------------------------------------- International equities (MSCI Europe, Australasia, Far East Index) - 9.21 - 1.78 - ------------------------------------------------------------------------------------------------------------------------- Fixed income (Lehman Brothers U.S. Aggregate Index) + 4.08 + 6.87 - ------------------------------------------------------------------------------------------------------------------------- Tax-exempt fixed income (Lehman Brothers Municipal Bond Index) + 1.47 + 2.79 - ------------------------------------------------------------------------------------------------------------------------- High yield bonds (Lehman Brothers U.S. Corporate High Yield 2% Issuer Capped Index) - 0.73 - 0.80 - ------------------------------------------------------------------------------------------------------------------------- Past performance is no guarantee of future results.

What factors influenced performance? o Security selection and overweight positions versus the benchmark in health care and information technology (IT) had the greatest negative effect on the Fund's comparative performance for the period. Selection decisions proved most unfavorable among health care providers and semiconductor and software names within the IT sector. Stock selection in financials (particularly capital markets and diversified services) and materials also detracted from results for the period. o Meanwhile, overweight positions in the consumer discretionary and energy sectors proved advantageous, but resultant gains were offset by disappointing stock selection. Stock-specific disappointments in specialty retailers and diversified services hampered results within consumer discretionary. Within energy, oil and gas names were the weakest performers, in particular oil refiners, whose profit margins were compressed by higher oil prices. o On the positive side, an underweight in telecommunication services enhanced the Fund's relative return for the period. Describe recent Portfolio activity. o During the period, we increased the Portfolio's exposure to energy. We reduced exposure to the consumer staples, industrials and consumer discretionary sectors. o Among our largest purchases were Occidental Petroleum Corp., Best Buy Co., Inc., Gap, Inc., MetLife, Inc. and Baxter International, Inc. Our largest sales included Merck & Co., Southern Copper Corp., Apollo Group, Inc., eBay, Inc. and Applied Materials, Inc. Describe Portfolio positioning at period-end. o On April 30, 2008, the Portfolio was overweight versus the benchmark in the IT, health care, energy and consumer discretionary sectors, and underweight in financials, consumer staples, utilities and telecommunication services. o We continue to expect lackluster U.S. economic growth over the next several quarters as counteracting forces prevent both an outright recession and a return to its historical trend or above-trend growth. While inflationary problems do exist in some emerging markets, we expect inflationary pressures in the U.S. to diminish in the months ahead, particularly since the credit squeeze and housing bust are both deflationary forces and the economy continues to operate below its potential. We recognize that economic risks remain and the rally in global equity prices late in the semi-annual period may have advanced to the point at which some additional corrective action could take place. In our view, however, the broad economic, corporate earnings and inflationary backdrop should benefit most market sectors and act as a foundation for improved market conditions, which we believe has already begun to fall into place.

APRIL 30, 2008 Fund Summary BlackRock Large Cap Growth Retirement Portfolio Portfolio Management Commentary How did the Portfolio perform? o The Portfolio underperformed the benchmark Russell 1000 Growth Index for the period from inception (January 3, 2008) through April 30, 2008. What factors influenced performance? o The Portfolio's underperformance for the period resulted primarily from stock selection factors, while asset allocation effects were modestly better. o Stock selection and an overweight versus the benchmark in the health care sector (mainly health care providers) had the greatest negative impact on comparative performance. Selection decisions in consumer discretionary (notably specialty retailers) and consumer staples (especially food and beverage companies) also detracted from results. o Elsewhere within the Portfolio, stock-specific weakness in information technology (IT), particularly in software names, hampered performance for the period. Within energy, underperformance was concentrated among oil refiners, whose profit margins were compressed by higher oil prices. An overweight in industrials proved advantageous, but the resultant gains were offset by disappointing stock selection in the sector. o On the positive side, an underweight in financials (mainly capital markets and diversified services) benefited the Portfolio's comparative performance, offsetting negative stock selection effects within the sector. An overweight in materials also enhanced the relative return. Describe recent Portfolio activity. o During the period, we increased the Portfolio's exposure to the health care, materials and IT sectors. We reduced exposure to the consumer discretionary, consumer staples and financials sectors. o Among our largest purchases were Microsoft Corp., Johnson & Johnson, Baxter International, Inc., Lincare Holdings, Inc. and Amazon Corp. Our largest sales included Merck & Co., Apollo Group, Inc., Honeywell International, Inc., EMC Corp. and Southern Copper Corp. Describe Portfolio positioning at period-end. o On April 30, 2008, the Portfolio was overweight relative to the benchmark in IT, health care, materials and industrials, and underweight in consumer staples, financials and utilities. o We continue to believe that U.S. economic growth will be flat or will increase no more than 2% over the next several quarters as counteracting forces prevent both an outright recession and a return to its historical trend or above-trend growth. While inflationary problems do exist in some emerging markets, we expect inflationary pressures in the U.S. to diminish in the months ahead, particularly since the credit squeeze and housing bust are both deflationary forces and the economy continues to operate below its potential. We recognize that economic risk remains and the rally in global equity prices late in the semi-annual period may have advanced to the point at which some additional corrective action could take place.

APRIL 30, 2008 5 Fund Summary BlackRock Large Cap Value Retirement Portfolio Portfolio Management Commentary How did the Portfolio perform? o The Portfolio underperformed the benchmark Russell 1000 Value Index for the period from inception (January 3, 2008) through April 30, 2008. What factors influenced performance? o Stock selection and an overweight position versus the benchmark in the health care sector (mainly health care providers) had the greatest negative impact on Portfolio performance for the period. Stock selection in consumer discretionary (particularly specialty retailers) and consumer staples (notably food and beverage companies) also detracted from the relative return. o An overweight in the energy sector proved advantageous, but was overshadowed by disappointing stock selection among oil and gas names. The underperformance was concentrated among oil refiners, whose profit margins were compressed by higher oil prices. Elsewhere within the Portfolio, security selection in financials (particularly capital markets names) and materials (primarily in metals and mining) hampered results. o On the positive side, stock selection in industrials, particularly in the machinery sub-sector, contributed positively to performance. The Portfolio's significant underweight in both the telecommunication services and utilities sectors also benefited the relative return. Describe recent Portfolio activity. o During the period, we increased the Portfolio's exposure to the industrials, energy and materials sectors. We reduced exposure to the consumer discretionary and consumer staples sectors. o Among our largest purchases were Pfizer, Inc., Merck & Co., Allstate Corp., Capital One Financial Corp. and Gap, Inc. Our largest sales included American International Group, Inc., Goldman Sachs Group, Inc., JP Morgan Chase & Co., Janus Capital Group Inc. and Mosaic Co. Describe Portfolio positioning at period-end. o On April 30, 2008, the Portfolio was overweight relative to the benchmark in information technology, health care, industrials and energy, and underweight in the financials, consumer staples, utilities, telecommunication services and consumer discretionary sectors. o We continue to expect lackluster U.S. economic growth over the next several quarters as counteracting forces prevent both an outright recession and a return to its historical trend or above-trend growth.

APRIL 30, 2008 About Fund Performance BlackRock Large Cap Series Funds, Inc. o Class K Shares are not subject to any sales charge. Class K Shares bear no ongoing distribution or service fees and are available only to eligible investors. Performance information reflects past performance and does not guarantee future results. Current performance may be lower or higher than the performance data quoted. Refer to www.blackrock.com/funds to obtain performance data current to the most recent month-end. Performance results do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. Performance data does not reflect this potential fee. Figures shown in each of the performance tables on pages 4 - 6 assume reinvestment of all dividends and capital gain distributions, if any, at net asset value on the ex-dividend date. Investment return and principal value of shares will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. Dividends paid to each class of shares will vary because of the different levels of service, distribution and transfer agency fees applicable to each class, which are deducted from the income available to be paid to shareholders. Disclosure of Expenses Shareholders of these Funds may incur the following charges: (a) expenses related to transactions, including sales charges, redemption fees and exchange fees; and (b) operating expenses including advisory fees, distribution fees including 12b-1 fees, and other Fund expenses. The expense examples below (which are based on a hypothetical investment of $1,000 invested on January 3, 2008 and held through April 30, 2008) are intended to assist shareholders both in calculating expenses based on an investment in each Fund and in comparing these expenses with similar costs of investing in other mutual funds. The tables provide information about actual account values and actual expenses. In order to estimate the expenses a shareholder paid during the period covered by this report, shareholders can divide their account value by $1,000 and then multiply the result by the number corresponding to their Fund and share class under the heading entitled "Expenses Paid During the Period." The tables also provide information about hypothetical account values and hypothetical expenses based on the Funds' actual expense ratio and an assumed rate of return of 5% per year before expenses. In order to assist shareholders in comparing the ongoing expenses of investing in these Funds and other funds, compare the 5% hypothetical example with the 5% hypothetical examples that appear in other funds' shareholder reports. The expenses shown in the tables are intended to highlight shareholders' ongoing costs only and do not reflect any transactional expenses, such as sales charges, redemption fees or exchange fees. Therefore, the hypothetical tables are useful in comparing ongoing expenses only, and will not help shareholders determine the relative total expenses of owning different funds. If these transactional expenses were included, shareholder expenses would have been higher.

Because the Fund is a feeder fund, the expense table reflects the expenses of both the feeder fund and the master portfolio in which it invests. ** Hypothetical 5% annual return before expenses is calculated by pro-rating the number of days in the most recent period divided by 366. See "Disclosure of Expenses" for further information on how expenses were calculated. BLACKROCK LARGE CAP SERIES FUNDS, INC.

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 accounting principles generally accepted in the United States of America, which may require the use of management accruals and estimates. Actual results may differ from these estimates. The percentages of Master Large Cap Core Portfolio, Master Large Cap Growth Portfolio and Master Large Cap Value Portfolio owned by BlackRock Large Cap Core Retirement Portfolio, BlackRock Large Cap Growth Retirement Portfolio and BlackRock Large Cap Value Retirement Portfolio, were 3.3%, 11.6% and 2.2%, respectively. The following is a summary of significant accounting policies followed by the Funds: Valuation of Investments: Each Fund records its investment in the corresponding Portfolio at fair value. Valuation of securities held by the Portfolios is discussed in Note 1 of the Portfolios' Notes to Financial Statements, which are included elsewhere in this report. Financial Accounting Standards Board ("FASB") Statement of Financial Accounting Standards No. 157, "Fair Value Measurements" ("FAS 157") clarifies the definition of fair value, establishes a framework for measuring fair values and requires additional disclosures about the use of fair value measurements. Various inputs are used in determining the fair value of investments, which are as follows: o Level 1 -- price quotations in active markets/exchanges for identical securities o Level 2 -- other observable inputs (including, but not limited to: quoted prices for similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks, and default rates) or other market-corroborated inputs) o Level 3 -- unobservable inputs based on the best information available in the circumstance, to the extent observable inputs are not available (including the Fund's own assumptions used in determining the fair value of investments) The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. The following table summarizes the inputs used as of April 30, 2008 in determining the fair valuation of the Fund's investments: Investments in Securities - -------------------------------------------------------------------------------- BlackRock BlackRock BlackRock Large Cap Core Large Cap Growth Large Cap Value Valuation Retirement Retirement Retirement Inputs Portfolio Portfolio Portfolio - -------------------------------------------------------------------------------- Level 1 -- -- -- Level 2 $147,619,797 $117,860,184 $108,531,586 Level 3 -- -- -- - -------------------------------------------------------------------------------- Total $147,619,797 $117,860,184 $108,531,586 ================================================================================ Investment Transactions and Net Investment Income: Investment transactions in the Portfolios are accounted for on a trade date basis. 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. Dividends and Distributions to Shareholders: Dividends and distributions paid by each Fund are recorded on the ex-dividend dates. 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 its shareholders. Therefore, no federal income tax provision is required. FASB Interpretation No. 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 investment companies, before being measured and recognized in the financial statements. The administrator has evaluated the application of FIN 48 to each Fund and has determined that the adoption of FIN 48 does not have a material impact on the Funds' financial statements. Each Fund files U.S. federal and various state and local tax returns. No income tax returns are currently under examination. Recent Accounting Pronouncement: In March 2008, Statement of Financial Accounting Standards No. 161, "Disclosures about Derivative Instruments and Hedging Activities -- an amendment of FASB Statement No. 133" ("FAS 161"), was issued and is effective for fiscal years beginning 12 BLACKROCK LARGE CAP SERIES FUNDS, INC. APRIL 30, 2008 Notes to Financial Statements (concluded) BlackRock Large Cap Series Funds, Inc. after November 15, 2008. FAS 161 is intended to improve financial reporting for derivative instruments by requiring enhanced disclosure that enables investors to understand how and why an entity uses derivatives, how derivatives are accounted for, and how derivative instruments affect an entity's results of operations and financial position. The administrator is currently evaluating the implications of FAS 161 and the impact on each Fund's financial statement disclosures, if any, is currently being assessed. Other: Expenses directly related to each Fund are charged to that Fund. Other operating expenses shared by several funds are pro-rated among those funds on the basis of relative net assets or other appropriate methods. Offering costs are amortized over a twelve month period beginning with the commencement of operations. 2. Transactions with Affiliates: Each Fund has entered into an Administration Agreement with BlackRock Advisors, LLC (the "Administrator"), an indirect, wholly owned subsidiary of BlackRock, Inc., to provide administrative services (other than investment advice and related portfolio activities). The Administrator does not receive an administration fee. The Administrator has contractually agreed to waive direct expenses of each Fund to the extent necessary to limit the ordinary annual operating expenses of each Fund to 0.65% of the average daily net assets of each Fund. This arrangement has a one year term and is renewable. Merrill Lynch & Co., Inc. ("Merrill Lynch") and The PNC Financial Services Group, Inc. ("PNC") are principal owners of BlackRock, Inc. Each Fund has also entered into separate Distribution Agreements and Distribution Plans with FAM Distributors, Inc. ("FAMD") and BlackRock Distributors, Inc. and its affiliates ("BDI") (collectively, the "Distributor"). FAMD is a wholly owned subsidiary of Merrill Lynch Group, Inc., and BDI is an affiliate of BlackRock, Inc. PFPC Inc., an indirect, wholly owned subsidiary of PNC and an affiliate of the Administrator, serves as transfer agent. Transfer agency fees borne by each of the Funds are comprised of those fees charged for all shareholder communications including shareholder reports, dividend and distribution notices, and proxy materials for shareholders meetings, as well as per account and per transaction fees related to servicing and maintenance of shareholder accounts, including the issuing, redeeming and transferring of shares of each class of the Fund, check writing, anti-money laundering services, and customer identification services. Certain officers and/or directors of the Funds are officers and/or directors of BlackRock, Inc. or its affiliates. 3.

See Notes to Financial Statements. 30 BLACKROCK LARGE CAP SERIES FUNDS, INC. APRIL 30, 2008 Notes to Financial Statements (Unaudited) Master Large Cap Series LLC 1. Significant Accounting Policies: Master Large Cap Core Portfolio, Master Large Cap Growth Portfolio and Master Large Cap Value Portfolio (the "Portfolios" or individually, a "Portfolio") constitute Master Large Cap Series LLC (the "Master LLC"). The Master LLC is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), and is organized as a Delaware limited liability company. The Limited Liability Company Agreement permits the Directors to issue non-transferable interests in the Master LLC, subject to certain limitations. The Portfolios' financial statements are prepared in conformity with accounting principles generally accepted in the United States of America, which may require the use of management accruals and estimates. Actual results may differ from these estimates. The following is a summary of significant accounting policies followed by the Portfolios: Valuation of Investments: Equity investments traded on a recognized securities exchange or the NASDAQ Global Market System are valued at the last reported sale price that day or the NASDAQ official closing price, if applicable. Equity investments traded on a recognized exchange for which there were no sales on that day are valued at the last available bid price. Investments in open-end investment companies are valued at net asset value each business day. In the event that application of these methods of valuation results in a price for an investment which is deemed not to be representative of the market value of such investment, the investment will be valued by a method approved by the Board of Directors (the "Board") as reflecting fair value ("Fair Value Assets"). When determining the price for Fair Value Assets, the investment advisor and/or sub-advisor seeks to determine the price that a Portfolio might reasonably expect to receive from the current sale of that asset in an arm's-length transaction. Fair value determinations shall be based upon all available factors that the investment advisor and/or sub-advisor deems relevant. The pricing of all Fair Value Assets is subsequently reported to the Board or a committee thereof. Investment Transactions and Investment Income: Investment transactions are recorded on the dates the transactions are entered into (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 a Portfolio has determined the ex-dividend date. Interest income is recognized on the accrual basis. Securities Lending: The Portfolios 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. A Portfolio typically receives the income on the loaned securities but does not receive the income on the collateral. Where a 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. A Portfolio may receive a flat fee for its loans. Loans of securities are terminable at any time and the borrower, after notice, is required to return borrowed securities within the standard time period for settlement of securities transactions. A Portfolio may pay reasonable 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, a Portfolio could experience delays and costs in gaining access to the collateral. A 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. Income Taxes: It is each Portfolio's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its taxable income to its shareholders. Therefore, no federal income tax provision is required. Under the applicable foreign tax laws, a withholding tax may be imposed on interest, dividends and capital gains at various rates. Effective April 30, 2008, each Portfolio implemented Financial Accounting Standards Board ("FASB") Interpretation No. 48, "Accounting for Uncertainty in Income Taxes -- an interpretation of FASB Statement No. 109" ("FIN 48"). 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 investment companies, before being measured and recognized in the financial statements. The investment advisor has evaluated the application of FIN 48 to the Portfolios, and has determined that the adoption of FIN 48 does not have a material impact on any Portfolios' financial statements. The Portfolios file U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The statutes of limitations on the Portfolios' U.S. federal tax returns remains open for the years ended October 31, 2004 through October 31, 2006. The statutes of limitations on the Portfolios' state and local tax returns may remain open for an additional year depending upon the jurisdiction. BLACKROCK LARGE CAP SERIES FUNDS, INC. APRIL 30, 2008 31 Notes to Financial Statements (continued) Master Large Cap Series LLC Recent Accounting Pronouncements: 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. The impact on the Portfolios' financial statement disclosures, if any, is currently being assessed. In addition, in February 2007, Statement of Financial Accounting Standards No. 159, "The Fair Value Option for Financial Assets and Financial Liabilities" ("FAS 159"), was issued and is effective for fiscal years beginning after November 15, 2007. Early adoption is permitted at the beginning of a fiscal year that begins on or before November 15, 2007 provided the entity also elects to apply the provisions of FAS 157. FAS 159 permits entities to choose to measure many financial instruments and certain other items at fair value that are not currently required to be measured at fair value. FAS 159 also establishes presentation and disclosure requirements designed to facilitate comparisons between entities that choose different measurement attributes for similar types of assets and liabilities. The impact on the Portfolios' financial statement disclosures, if any, is currently being assessed. In March 2008, Statement of Financial Accounting Standards No. 161, "Disclosures about Derivative Instruments and Hedging Activities -- an amendment of FASB Statement No. 133" ("FAS 161"), was issued and is effective for fiscal years beginning after November 15, 2008. FAS 161 is intended to improve financial reporting for derivative instruments by requiring enhanced disclosure that enables investors to understand how and why an entity uses derivatives, how derivatives are accounted for, and how derivative instruments affect an entity's results of operations and financial position. The investment advisor is currently evaluating the implications of FAS 161 and the impact on the Portfolios' financial statement disclosures, if any, is currently being assessed. Bank Overdraft: Master Large Cap Core Portfolio and Master Large Cap Growth Portfolio recorded a bank overdraft, which resulted from management estimates of available cash. Other: Expenses directly related to one of the Portfolios are charged to that Portfolio. Other operating expenses shared by several Portfolios are pro-rated among those Portfolios on the basis of relative net assets or other appropriate methods. 2. Investment Advisory Agreement and Other Transactions with Affiliates: The Master LLC, on behalf of each Portfolio, has entered into an Investment Advisory Agreement with BlackRock Advisors, LLC (the "Advisor"), an indirect, wholly owned subsidiary of BlackRock, Inc., to provide investment advisory and administration services. Merrill Lynch & Co., Inc. ("Merrill Lynch") and The PNC Financial Services Group, Inc. are principal owners of BlackRock, Inc. The Advisor 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. Master Large Cap Core Portfolio pays a monthly fee at an annual rate of 0.50% of the average daily net assets not exceeding $1 billion, 0.45% of average daily net assets in excess of $1 billion but not exceeding $5 billion and 0.40% of average daily net assets in excess of $5 billion; Master Large Cap Growth Portfolio pays a monthly fee at an annual rate of 0.50% of the average daily net assets not exceeding $5 billion and 0.45% 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 0.50% of the average daily net assets not exceeding $3 billion and 0.45% of average daily net assets in excess of $3 billion.
