Healthy nonfinancial corporate profits and robust exporting activity remained among the few bright spots, helping the economy to grow at a modest, but still positive, pace. The Federal Reserve Board (the "Fed") has been aggressive in its attempts to stoke economic growth and ease financial market instability. In addition to slashing the target federal funds rate 325 basis points (3.25%) between September 2007 and April 2008, the central bank introduced the new Term Securities Lending Facility, granted broker-dealers access to the discount window and used its own balance sheet to help negotiate the sale of Bear Stearns. As widely anticipated, the end of the period saw a pause in Fed action, as the central bank held the target rate steady at 2.0% amid rising inflationary pressures. As the Fed's bold response to the financial crisis helped ease credit turmoil and investor anxiety, U.S. equity markets sank sharply over the last six months, notwithstanding a brief rally in the spring. International markets were not immune to the tumult, with most regions also registering declines. Treasury securities also traded in a volatile fashion, but generally rallied (yields fell as prices correspondingly rose), with investors continuing to seek safety as part of a broader flight to quality. The yield on 10-year Treasury issues, which fell to 3.34% in March 2008, climbed up to the 4.20% range in mid-June as investors temporarily shifted out of Treasury issues in favor of riskier assets (such as stocks and other high-quality fixed income sectors), then reversed course and declined to 3.99% by period-end when credit fears re-emerged. Tax-exempt issues eked out gains for the reporting period, but underperformed their taxable counterparts, as the group continued to be pressured by problems among municipal bond insurers and the breakdown in the market for auction rate securities. The major benchmark indexes generated results that largely reflected heightened investor risk aversion: Total Returns as of June 30, 2008 6-month 12-month =============================================================================================================== U.S. equities (S&P 500 Index) (11.91)% (13.12)% - --------------------------------------------------------------------------------------------------------------- Small cap U.S. equities (Russell 2000 Index) (9.37)% (16.19)% - --------------------------------------------------------------------------------------------------------------- International equities (MSCI Europe, Australasia, Far East Index) (10.96)% (10.61)% - --------------------------------------------------------------------------------------------------------------- Fixed income (Lehman Brothers U.S. Aggregate Index) 1.13% 7.12% - --------------------------------------------------------------------------------------------------------------- Tax-exempt fixed income (Lehman Brothers Municipal Bond Index) 0.02% 3.23% - --------------------------------------------------------------------------------------------------------------- High yield bonds (Lehman Brothers U.S. Corporate High Yield 2% Issuer Capped Index) (1.08)% (1.74)% - --------------------------------------------------------------------------------------------------------------- Past performance is no guarantee of future results.

Returns, after fees and expenses, for the Portfolio's respective share classes trailed the benchmark approximately by the amount of such classes' respective share-class fees and expenses. Describe the market environment. o U.S. equity markets endured a remarkably difficult first six months of 2008, with most indexes finishing in negative territory against a backdrop of slowing economic growth, continued credit market strains and rising food and energy prices. o The predominant issues dominating financial headlines throughout most of 2007 -- problems with subprime mortgages and the resulting credit crunch -- intensified during the first quarter of 2008. Credit availability continued to contract, culminating in the dramatic collapse of Bear Stearns in mid-March. Fears of economic recession, combined with a rapidly sinking dollar and surging commodities prices, caused investors to grow increasingly risk-averse as they dumped stocks in favor of safer alternatives, such as U.S. Treasury issues. In the end, U.S. stocks posted their worst quarterly return since 2002. o After a grueling first quarter, the second quarter brought some reprieve, as U.S. equities rallied in April and May on expectations that accommodative Fed action, fiscal stimulus and the bailout of Bear Stearns signified that the worst had passed. Unfortunately, these gains quickly evaporated, as crude oil topped $140 per barrel, consumer confidence plummeted, inflation concerns resurfaced and news of additional write-downs and capital raising in the financials sector tempered investor optimism. o For the six months, large-cap stocks trailed their small-cap counterparts, as the S&P 500 Index returned (11.91)%, while the small cap S&P 600 Index returned (7.09)%. Within the S&P 500 Index, the growth style of investing significantly outperformed the value style for the period. o Turning to sector performance, energy (+8.88%) and materials (+1.26%) were the only sectors to post positive returns, while financials (-29.73%), telecommunication services (-17.30%) and industrials (-13.65%) were the weakest performers. Describe recent portfolio activity. o Throughout the semi-annual period, as changes were made to the composition of the S&P 500 Index, the Series purchased and sold securities to maintain its objective of replicating the risks and return of the benchmark. Describe portfolio positioning at period-end. o In keeping with its investment objective, the Series remains positioned to match the risk characteristics of its benchmark, irrespective of the market's future direction. The views expressed reflect the opinions of BlackRock as of the date of this report and are subject to change based on changes in market, economic or other conditions.

Because the Portfolio is a feeder fund, the expense table example reflects the expense of both the feeder fund and the master fund in which it invests. 2 Hypothetical 5% annual return before expenses is calculated by pro-rating the number of days in the most recent fiscal period divided by 366. See "Disclosure of Expenses" on page 6 for further information on how expenses were calculated. 4 BLACKROCK INDEX EQUITY PORTFOLIO JUNE 30, 2008 Total Return Based on a $10,000 Investment A line graph depicting the growth of an investment in the Fund's Institutional and Investor A Shares compared to growth of an investment in the S&P 500(R) Index.

See "About Portfolio Performance" on page 6 for a detailed description of share classes, including any related sales charges and fees. Past performance is not indicative of future results. BLACKROCK INDEX EQUITY PORTFOLIO JUNE 30, 2008 5 About Portfolio Performance o Institutional Shares are not subject to any 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 0.15% per year (but no distribution fee) and are available only to eligible investors. o Investor A Shares incur a maximum initial sales charge (front-end load) of 3% and a service fee of 0.15% 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 0.15% 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 0.15% per year. In addition, Investor C Shares are subject to a 1% contingent deferred sales charge if redeemed within one year of purchase. 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. The Portfolio may charge a 2% redemption fee for sales or exchanges of shares within 30 days of purchase or exchange. Performance results do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. Performance data does not reflect this potential fee. Figures shown in each of the performance tables on page 5 assume reinvestment of all dividends and capital gain distributions, if any, at net asset value on the ex-dividend date. Investment return and principal value of shares will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. Dividends paid to each class of shares will vary because of the different levels of service, distribution and transfer agency fees applicable to each class, which are deducted from the income available to be paid to shareholders. The Portfolio's administrator waived a portion of its fee. Without such waiver, the Portfolio's returns would have been lower. Disclosure of Expenses Shareholders of this Portfolio may incur the following charges: (a) expenses related to transactions, including sales charges, redemption fees and exchange fees; and (b) operating expenses, including administration fees, distribution fees including 12b-1 fees, and other Portfolio expenses. The expense example on page 4 (which is based on a hypothetical investment of $1,000 invested on January 1, 2008 and held through June 30, 2008) is intended to assist shareholders both in calculating expenses based on an investment in the Portfolio and in comparing these expenses with similar costs of investing in other mutual funds. The table provides information about actual account values and actual expenses. In order to estimate the expenses a shareholder paid during the period covered by this report, shareholders can divide their account value by $1,000 and then multiply the result by the number corresponding to their share class under the heading entitled "Expenses Paid During the Period." The table also provides information about hypothetical account values and hypothetical expenses based on the Portfolio's actual expense ratio and an assumed rate of return of 5% per year before expenses. In order to assist shareholders in comparing the ongoing expenses of investing in this Portfolio and other funds, compare the 5% hypothetical example with the 5% hypothetical examples that appear in other funds' shareholder reports. The expenses shown in the table are intended to highlight shareholders' ongoing costs only and do not reflect any transactional expenses, such as sales charges, redemption fees or exchange fees. Therefore, the hypothetical information is useful in comparing ongoing expenses only, and will not help shareholders determine the relative total expenses of owning different funds. If these transactional expenses were included, shareholder expenses would have been higher. 6 BLACKROCK INDEX EQUITY PORTFOLIO JUNE 30, 2008 Statement of Assets and Liabilities BlackRock Index Equity Portfolio June 30, 2008 (Unaudited) =================================================================================================================================== Assets - ----------------------------------------------------------------------------------------------------------------------------------- Investment at value -- Master S&P 500 Index Series (the "Series") (cost -- $968,874,842) ........................... $ 812,386,463 Series interest sold receivable .................................................................................... 1,408,154 Capital shares sold receivable ..................................................................................... 399,934 Prepaid expenses ................................................................................................... 55,139 ------------- Total assets ....................................................................................................... 814,249,690 ------------- =================================================================================================================================== Liabilities - ----------------------------------------------------------------------------------------------------------------------------------- Capital shares redeemed payable .................................................................................... $ 1,808,088 Distribution fees payable .......................................................................................... 149,107 Administration fees payable ........................................................................................ 73,280 Other affiliates payable ........................................................................................... 56,914 Income dividends payable ........................................................................................... 614 Officer's and Directors' fees payable .............................................................................. 178 Other accrued expenses payable ..................................................................................... 188,130 ------------- Total liabilities .................................................................................................. 2,276,311 ------------- =================================================================================================================================== Net Assets - ----------------------------------------------------------------------------------------------------------------------------------- Net assets ......................................................................................................... $ 811,973,379 ============= =================================================================================================================================== Net Assets Consist of - ----------------------------------------------------------------------------------------------------------------------------------- Institutional Shares, $0.001 par value, unlimited number of shares authorized ...................................... $ 16,718 Service Shares, $0.001 par value, unlimited number of shares authorized ............................................ 896 Investor A Shares, $0.001 par value, unlimited number of shares authorized ......................................... 9,102 Investor B Shares, $0.001 par value, unlimited number of shares authorized ......................................... 1,313 Investor C Shares, $0.001 par value, unlimited number of shares authorized ......................................... 5,112 Paid-in capital in excess of par ................................................................................... 550,286,587 Undistributed net investment income ................................................................................ 3,869,411 Accumulated net realized gain allocated from the Series ............................................................ 414,272,619 Net unrealized appreciation/depreciation allocated from the Series .................................................

See Notes to Financial Statements. 14 BLACKROCK INDEX EQUITY PORTFOLIO JUNE 30, 2008 Notes to Financial Statements (Unaudited) BlackRock Index Equity Portfolio 1. Significant Accounting Policies: BlackRock Index Equity Portfolio (the "Portfolio"), a part of BlackRock FundsSM (the "Fund"), is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end management investment company. The Portfolio seeks to achieve its investment objective by investing all of its assets in Master S&P 500 Index Series (the "Series") of Quantitative Master Series LLC. The value of the Portfolio's investment in the Series reflects the Portfolio's proportionate interest in the net assets of the Series. The performance of the Portfolio is directly affected by the performance of the Series. The financial statements of the Series, including the Summary Schedule of Investments, are included elsewhere in this report and should be read in conjunction with the Portfolio's financial statements. The Portfolio's 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 percentage of the Series owned by the Portfolio at June 30, 2008 was 25.7%. The Portfolio offers multiple classes of shares. Institutional and Service shares are sold without a sales charge and only to certain eligible investors. Investor A Shares are generally sold with a front-end sales charge. Investor B and Investor C Shares may be subject to a contingent deferred sales charge. All classes of shares have identical voting, dividend, liquidation and other rights and the same terms and conditions, except that Investor A, Investor B and Investor C Shares bear certain expenses related to the shareholder servicing of such shares, and Investor B and Investor C Shares also bear certain expenses related to the distribution of such shares. Each class has exclusive voting rights with respect to matters relating to its shareholder servicing and distribution expenditures (except that Investor B shareholders may vote on material changes to the Investor A distribution plan). The following is a summary of significant accounting policies followed by the Portfolio: Valuation of Investments: The Portfolio records its investment in the Series at fair value. Valuation of securities held by the Series is discussed in Note 1 of the Series' Notes to Financial Statements, which are included elsewhere in this report. Effective January 1, 2008, the Portfolio adopted Financial Accounting Standards Board Statement of Financial Accounting Standards No. 157, "Fair Value Measurements" ("FAS 157"). 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 Portfolio's own assumption 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 June 30, 2008 in determining the fair valuation of the Portfolio's investments: - -------------------------------------------------------------------------------- Investments in Valuation Inputs Securities - -------------------------------------------------------------------------------- Level 1 .......................................................... -- Level 2 .......................................................... $812,386,463 Level 3 .......................................................... -- - -------------------------------------------------------------------------------- Total $812,386,463 ============ Investment Transactions and Net Investment Income: Investment transactions in the Series are accounted for on a trade date basis. The Portfolio records daily its proportionate share of the Series' income, expenses and realized and unrealized gains and losses. In addition, the Portfolio accrues its own expenses. Income and realized and unrealized gains and losses are allocated daily to each class based on its relative net assets. Dividends and Distributions to Shareholders: Dividends and distributions paid by the Portfolio are recorded on the ex-dividend dates. Income Taxes: It is the 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. The Portfolio files U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The statute of limitations on the Portfolio's U.S. federal tax returns remains open for the years ended December 31, 2004 through December 31, 2006. The statutes of limitations on the Portfolio's state and local tax returns may remain open for an additional year depending upon the jurisdiction. 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 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 BLACKROCK INDEX EQUITY PORTFOLIO JUNE 30, 2008 15 Notes to Financial Statements (continued) BlackRock Index Equity Portfolio affect an entity's results of operations and financial position. The impact on the Portfolio's financial statement disclosures, if any, is currently being assessed. Other: Expenses directly related to the Portfolio or its classes are charged to that Portfolio or class. Other operating expenses shared by several funds are pro-rated among those funds on the basis of relative net assets or other appropriate methods. Other expenses of the Portfolio are allocated daily to each class based on its relative net assets. 2. Transactions with Affiliates: The Fund, on behalf of the Portfolio, has entered into an Administration Agreement with BlackRock Advisors, LLC and State Street Bank and Trust Company (collectively, the "Administrator"). Merrill Lynch & Co., Inc. ("Merrill Lynch") and The PNC Financial Services Group, Inc. ("PNC") are principal owners of BlackRock, Inc. The Portfolio pays the Administrator a monthly fee based upon the average daily value of the Portfolio's net assets at the following annual rates for the performance of administrative services other than investment advice and related portfolio activities necessary to the operation of the Portfolio: 0.075% of the Portfolio's average daily net assets not exceeding $500 million; 0.065% of average daily net assets in excess of $500 million but not exceeding $1 billion; and 0.055% of average daily net assets in excess of $1 billion. In addition, each of the share classes is charged an administration fee based upon the average daily net assets of each respective class at the following rates for the performance of administrative services other than investment advice and related portfolio activities necessary to the operation of the portfolio: 0.025% of the first $500 million, 0.015% of the next $500 million and 0.005% of assets in excess of $1 billion. BlackRock contractually agreed to waive or reimburse fees or expenses until February 1, 2009 in order to limit expenses. This agreement is reviewed annually by the Fund's Board of Trustees. The current expense limitation as a percentage of net assets are as follows: 0.18% for Institutional; 0.615% for Service; 0.785% for Investor A, and 1.24% for Investor B and Investor C. These amounts are shown as fees waived by the Administrator on the Statement of Operations. If after two years following a waiver or reimbursement of the operating expenses of a share class that previously received a waiver or reimbursement from BlackRock are less than the expense limit for that share class, BlackRock is entitled to reimbursement by such share class up to the amount of fees waived or expenses reimbursed under the agreement if: (1) the Portfolio of which the share class is a part has more than $50 million in assets, (2) BlackRock continues to be the Portfolio's investment advisor and (3) the Board of the Fund approved the payments to BlackRock at the previous quarterly meeting. At June 30, 2008, the amounts subject to possible future reimbursement under the expense limitation agreement are as follows: - -------------------------------------------------------------------------------- Expiring Expiring Expiring Expiring Total Waivers January 31, January 31, January 31, January 31, Subject to 2009 2010 2011 2012 Reimbursement - -------------------------------------------------------------------------------- $131,162 $87,300 $20,683 $36,614 $275,759 - -------------------------------------------------------------------------------- Waivers of $1,120,125 previously recognized by the Portfolio, which may have been subject to recoupment, expired on January 31, 2008. The Portfolio 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.

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 Series' own assumption 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. For information about the Series' policy regarding valuation of investments and other significant accounting policies, please refer to Note 1 of the Notes to Financial Statements.

See Notes to Financial Statements. 26 BLACKROCK INDEX EQUITY PORTFOLIO JUNE 30, 2008 Notes to Financial Statements (Unaudited) Master S&P 500 Index Series 1. Significant Accounting Policies: Master S&P 500 Index Series (the "Series"), a non-diversified investment company, is part of Quantitative Master 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 Board of Directors (the "Board") to issue non-transferable interests in the Master LLC, subject to certain limitations. The Series' 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 Series: 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. For equity investments traded on more than one exchange, the last reported sale price on the exchange where the stock is primarily traded is used. Equity investments traded on a recognized exchange for which there were no sales on that day are valued at the last available bid price. If no bid or ask price is available, the prior day's price will be used, unless it is determined that such prior day's price no longer reflects the fair value of the security. Financial futures contracts are traded on exchanges and are valued at their last sale price. Short-term securities are valued at amortized cost. 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 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 the 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. Derivative Financial Instruments: The Series may engage in various portfolio investment strategies to increase the return of the Series and to hedge, or protect, its exposure to interest rate movements and movements in the securities markets. Losses may arise if the value of the contract decreases due to an unfavorable change in the price of the underlying security, or if the counterparty does not perform under the contract. o Financial futures contracts -- The Series may purchase or sell financial futures contracts and options on such financial futures contracts. Futures contracts are contracts for delayed delivery of securities at a specific future date and at a specific price or yield. Upon entering into a contract, the Series deposits and maintains as collateral such initial margin as required by the exchange on which the transaction is effected. Pursuant to the contract, the Series 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 margin variation and are recognized by the Series as unrealized gains or losses. When the contract is closed, the Series 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. Segregation: In cases in which the 1940 Act and the interpretive positions of the Securities and Exchange Commission ("SEC") require that the Series segregates assets in connection with certain investments (e.g., futures) or certain borrowings, the Series will, consistent with certain interpretive letters issued by the SEC, designate on its books and records cash or other liquid debt securities having a market value at least equal to the amount that would otherwise be required to be physically segregated. 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. Interest income is recognized on the accrual basis. Securities Lending: The Series 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 Series and any additional required collateral is delivered to the Series on the next business day. The Series typically receives the income on the loaned securities but does not receive the income on the collateral. Where the Series 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 the standard time period for settlement of securities transactions. The Series 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, the Series could experience delays and costs in gaining access to the collateral. The Series 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. BLACKROCK INDEX EQUITY PORTFOLIO JUNE 30, 2008 27 Notes to Financial Statements (concluded) Master S&P 500 Index Series Income Taxes: The Series is classified as a "pass-through entity" for federal income tax purposes. As such, each investor in the Series is treated as owner of its proportionate share of the net assets, income, expenses and realized and unrealized gains and losses of the Series. Therefore, no federal income tax provision is required. It is intended that the Series' assets will be managed so an investor in the Series can satisfy the requirements of Subchapter M of the Internal Revenue Code. The Series files U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The statute of limitations on the Series' U.S. federal tax returns remains open for the years ended December 31, 2004 through December 31, 2006. The statutes of limitations on the Series' state and local tax returns may remain open for an additional year depending upon the jurisdiction. 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 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 impact on the Series' financial statement disclosures, if any, is currently being assessed. Other: Expenses directly related to the Series are charged to that Series. Other operating expenses shared by several funds are pro-rated among those funds 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 the Series, 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 the Series' investments and provides the necessary personnel, facilities, equipment and certain other services necessary to the operations of the Series. For such services, the Portfolio pays the Advisor a monthly fee at an annual rate of 0.01% of the average daily value of the Series' net assets. However, the Advisor has entered into a contract with the Master LLC, on behalf of the Series, that provides that the investment advisory fee for the Series, when combined with the administrative fee of a certain feeder fund, will not exceed a specified amount. As a result, the Series pays a monthly fee at an annual rate of 0.005% of the average daily value of the Series' net assets. The waiver is shown as fees waived by the Advisor on the Statement of Operations. The Advisor has entered into a separate sub-advisory agreement with BlackRock Investment Management, LLC ("BIM"), an affiliate of the Advisor, under which the Advisor pays BIM, for services it provides, a monthly fee that is a percentage of the investment advisory fee paid by the Series to the Advisor. For the six months ended June 30, 2008, the Series reimbursed the Advisor $28,322 for certain accounting services, which are included in accounting services in the Statement of Operations. The Master LLC, on behalf of the Series, has received an exemptive order from the SEC permitting it to lend portfolio securities to Merrill Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S"), a wholly owned subsidiary of Merrill Lynch, or its affiliates. As of June 30, 2008, the Series lent securities with a value of $73,856,236 to MLPF&S or its affiliates. Pursuant to that order, the Series has retained BIM as the securities lending agent for a fee based on a share of the returns on investment of cash collateral. BIM may, on behalf of the Series, invest cash collateral received by the Series for such loans, among other things, in a private investment company managed by the Advisor or in registered money market funds advised by the Advisor or its affiliates. For the six months ended June 30, 2008, BIM received $293,072 in securities lending agent fees. Certain officers and/or directors of the Master LLC are officers and/or directors of BlackRock, Inc. or its affiliates. 3.Investments: Purchases and sales of investments, excluding short-term securities, for the six months ended June 30, 2008 were $145,634,350 and $238,335,482, respectively. 4. Short-Term Borrowings: The Master LLC, on behalf of the Series, along with certain other funds managed by the Advisor and its affiliates, is party to a $500,000,000 credit agreement with a group of lenders. The Series may borrow under the credit agreement to fund shareholder redemptions and for other lawful purposes other than for leverage. The Series may borrow up to the maximum amount allowable under the Series' current prospectus and statement of additional information, subject to various other legal, regulatory or contractual limits. On November 21, 2007, the credit agreement was renewed for one year under substantially the same terms. The Series pays a commitment fee of 0.06% per annum based on the Series' pro rata share of the unused portion of the credit agreement. Amounts borrowed under the credit agreement bear interest at a rate equal to, at each fund's election, the federal funds rate plus 0.35% or a base rate as defined in the credit agreement. The Series did not borrow under the credit agreement during the six months ended June 30, 2008. 28 BLACKROCK INDEX EQUITY PORTFOLIO JUNE 30, 2008 Disclosure of Investment Advisory Agreement and Subadvisory Agreement BlackRock Index Equity Portfolio (the "Portfolio") of BlackRock Funds (the "Fund") currently invests all of its investable assets in the Master S&P 500 Index Series (the "Series") of Quantitative Master Series LLC (the "Master LLC"). Accordingly, the Portfolio does not require investment advisory services, since all investments are made at the Series level. Prior to June 1, 2007, the Portfolio invested all of its investable assets in The U.S. Large Company Series of The DFA Investment Trust Company. The Board of Directors of the Master LLC met in person in April and June 2008 to consider the approval of the Master LLC's investment advisory agreement entered into on behalf of the Series with the Master LLC's investment adviser, BlackRock Advisors, LLC (the "Adviser") (the "Advisory Agreement"). The Board of the Master LLC also considered the approval of the subadvisory agreement with respect to the Series between the Adviser and BlackRock Investment Management, LLC (the "Subadviser") (the "Subadvisory Agreement"). The Adviser and the Subadviser are referred to herein as "BlackRock." The Advisory Agreement and the Subadvisory Agreement are referred to herein as the "Agreements." Since the Portfolio invests all of its investable assets in the Series, the Board of Directors of the Fund also considered the approval of the Agreements. For ease and clarity of presentation, the Board of Directors of the Master LLC and the Board of Directors of the Fund, which are comprised of the same thirteen individuals, are herein referred to collectively as the "Boards," the members of which are referred to as "Directors." Activities and Composition of the Board The Boards each consist of thirteen individuals, eleven of whom are not "interested persons" of either the Fund or the Master LLC as defined in the Investment Company Act of 1940, as amended (the "1940 Act") (the "Independent Directors"). The Boards are responsible for the oversight of the operations of the Portfolio and the Series, as pertinent, and perform the various duties imposed on the directors of investment companies by the 1940 Act. The Independent Directors have retained independent legal counsel to assist them in connection with their duties. The Co-Chairs of each Board are both Independent Directors. The Boards established four standing committees: an Audit Committee, a Governance and Nominating Committee, a Compliance Committee and a Performance Oversight Committee, each of which is composed of, and chaired by, Independent Directors. The Agreements Upon the consummation of the combination of BlackRock's investment management business with Merrill Lynch & Co., Inc.'s investment management business, including Merrill Lynch Investment Managers, L.P. and certain affiliates (the "Transaction"), the Master LLC entered into an Advisory Agreement with the Adviser with respect to the Series with an initial two-year term and the Adviser entered into a Subadvisory Agreement with the Subadviser with respect to the Series with an initial two-year term. Consistent with the 1940 Act, prior to the expiration of each Agreement's initial two-year term, the Boards are required to consider the continuation of the Agreements on an annual basis. In connection with this process, the Boards assessed, among other things, the nature, scope and quality of the services provided to the Portfolio and/or the Series by the personnel of BlackRock and its affiliates, including investment management, administrative services, shareholder services, oversight of fund accounting and custody, marketing services and assistance in meeting legal and regulatory requirements. The Boards also received and assessed information regarding the services provided to the Portfolio and/or the Series by certain unaffiliated service providers. Throughout the year, the Boards, acting directly and through its committees, considers at each of its meetings factors that are relevant to its annual consideration of the renewal of the Fund's Agreements, including the services and support provided to the Fund and its shareholders. Among the matters the Boards considered, as pertinent, were: (a) investment performance for one, three and five years, as applicable, against peer funds, as well as senior management's and portfolio managers' analysis of the reasons for underperformance, if applicable; (b) fees, including advisory, administration, if applicable, and other fees paid to BlackRock and its affiliates by the Portfolio and/or the Series, such as transfer agency fees and fees for marketing and distribution; (c) Portfolio and Series operating expenses; (d) the resources devoted to and compliance reports relating to the Portfolio's and the Series' investment objective, policies and restrictions; (e) the Fund's and the Master LLC's compliance with its respective Code of Ethics and compliance policies and procedures; (f) the nature, cost and character of non-investment management services provided by BlackRock and its affiliates; (g) BlackRock's and other service providers' internal controls; (h) BlackRock's implementation of the proxy voting guidelines approved by the Boards; (i) the use of brokerage commissions and spread and execution quality; (j) valuation and liquidity procedures; and (k) periodic overview of BlackRock's business, including BlackRock's response to the increasing scale of its business. BLACKROCK INDEX EQUITY PORTFOLIO JUNE 30, 2008 29 Disclosure of Investment Advisory Agreement and Subadvisory Agreement (continued) Board Considerations in Approving the Advisory Agreement and Subadvisory Agreement The Approval Process: Prior to the April 16, 2008 meeting, at which approval of the Agreements was to be considered, the Boards requested and received materials specifically relating to the Agreements. The Board is engaged in an ongoing process with BlackRock to continuously review the nature and scope of the information provided to better assist its deliberations. These materials included (a) information independently compiled and prepared by Lipper, Inc. ("Lipper") on the Portfolio's fees and expenses and the investment performance of the Portfolio as compared with a peer group of funds as determined by Lipper ("Peers"); (b) information on the profitability of the Agreements to BlackRock and certain affiliates, including their other relationships with the Portfolio and/or the Series, and a discussion of fall-out benefits; (c) a general analysis provided by BlackRock concerning investment advisory fees charged to other clients, such as institutional and closed-end funds under similar investment mandates, as well as the performance of such other clients; (d) a report on economies of scale; (e) sales and redemption data regarding the Portfolio's shares and the Series' interests, and (f) an internal comparison of management fees classified by Lipper, if applicable. At the April 16, 2008 meeting, the Boards requested and subsequently received from BlackRock (i) comprehensive analysis of total expenses on a fund-by-fund basis; (ii) further analysis of investment performance; (iii) further data regarding Portfolio and Series profitability, Portfolio and Series size and Portfolio and Series fee levels; and (iv) additional information on sales and redemptions. The Boards also considered other matters they deemed important to the approval process, such as payments made to BlackRock or its affiliates relating to the distribution of Portfolio shares, services related to the valuation and pricing of portfolio holdings of the Series, allocation of Series brokerage fees (including the benefits of "soft dollars"), and direct and indirect benefits to BlackRock and its affiliates from their relationship with the Portfolio and the Series. The Boards did not identify any particular information as controlling, and each Director may have attributed different weights to the various items considered. At an in-person meeting held on April 16, 2008, the Boards discussed and considered materials provided. As a result of the discussions, the Boards requested and BlackRock provided additional information, as detailed above, in advance of the June 3 - 4, 2008 Board meeting. At an in-person meeting held on June 3 - 4, 2008, the Boards, including the Independent Directors, unanimously approved the continuation of (a) the Advisory Agreement between the Adviser and the Master LLC with respect to the Series for a one-year term ending June 30, 2009 and (b) the Subadvisory Agreement between the Adviser and the Subadviser with respect to the Series for a one-year term ending June 30, 2009. The Boards considered all factors they believed relevant with respect to the Portfolio and the Series, as relevant, including, among other factors: (i) the nature, extent and quality of the services provided by BlackRock; (ii) the investment performance of the Portfolio and BlackRock portfolio management; (iii) the advisory fee and the cost of the services and profits to be realized by BlackRock and certain affiliates from the relationships with the Portfolio and the Series; and (iv) economies of scale. A. Nature, Extent and Quality of the Services: The Boards, including the Independent Directors, reviewed the nature, extent and quality of services provided by BlackRock, including the investment advisory services and the resulting performance of the Portfolio. Throughout the year, the Boards compared the Portfolio's performance -- both including and excluding the effects of the Portfolio's fees and expenses -- to the performance of a comparable group of mutual funds as classified by Lipper and the performance of at least one relevant index or combination of indices. The Boards met with BlackRock's senior management personnel responsible for investment operations, including the senior investment officers. The Boards also reviewed the materials provided by the Series' portfolio management team discussing performance and the Series' investment objective, strategies and outlook. The Boards considered, among other factors, the number, education and experience of BlackRock's investment personnel generally, and of the Series' portfolio management team; BlackRock's portfolio trading capabilities; BlackRock's use of technology; BlackRock's commitment to compliance; and BlackRock's approach to training and retaining portfolio managers and other research, advisory and management personnel. The Boards also reviewed BlackRock's compensation structure with respect to the portfolio management team of the Series and BlackRock's ability to attract and retain high-quality talent. 30 BLACKROCK INDEX EQUITY PORTFOLIO JUNE 30, 2008 Disclosure of Investment Advisory Agreement and Subadvisory Agreement (continued) In addition to advisory services, the Boards considered the quality of the administrative and non-investment advisory services provided to the Portfolio and the Series. BlackRock and its affiliates provide the Portfolio and the Series, as pertinent, with certain administrative, transfer agency, shareholder and other services (in addition to any such services provided to the Portfolio and the Series by third parties) and officers and other personnel as are necessary for the operations of the Portfolio and the Series. In addition to investment advisory services, BlackRock and its affiliates provide the Portfolio and the Series with other services, including, as pertinent, (a) preparing disclosure documents, such as the prospectus, the statement of additional information and shareholder reports; (b) assisting with daily accounting and pricing; (c) overseeing and coordinating the activities of other service providers; (d) organizing Board meetings and preparing the materials for such Board meetings; (e) providing legal and compliance support; and (f) performing other administrative functions necessary for the operation of the Portfolio and the Series, such as tax reporting and fulfilling regulatory filing requirements. The Boards reviewed the structure and duties of BlackRock's fund administration, accounting, legal and compliance departments. B. The Investment Performance of the Portfolio, the Series and BlackRock: The Boards, including the Independent Directors, also reviewed and considered the performance history of the Portfolio. In preparation for the April 16, 2008 meeting, the Boards were provided with reports, independently prepared by Lipper, which included a comprehensive analysis of the Portfolio's performance. The Boards also reviewed a narrative and statistical analysis of the Lipper data that was prepared by BlackRock, which analyzed various factors that affect Lipper's rankings. In connection with their review, the Boards received and reviewed information regarding the investment performance of the Portfolio as compared to a representative group of similar funds as determined by Lipper and to all funds in the Portfolio's applicable Lipper category. The Boards were provided with a description of the methodology used by Lipper to select peer funds. The Boards regularly review the performance of the Portfolio throughout the year. The Boards attach more importance to performance over relatively long periods of time, typically three to five years. The Boards noted that the Portfolio's performance was above the median for the Portfolio's Peers in the one- and three-year periods but was slightly below the median for the five-year period reported. C. Consideration of the Advisory Fees and the Cost of the Services and Profits to be Realized by BlackRock and its Affiliates from the Relationship with the Portfolio and the Series: The Boards, including the Independent Directors, reviewed the Series' contractual advisory fee rates compared with the other funds in the Portfolio's Lipper category. They also compared the Portfolio's total expenses to those of other comparable funds. The Boards considered the services provided and the fees charged by BlackRock to other types of clients with similar investment mandates, including separately managed institutional accounts. The Boards received and reviewed statements relating to BlackRock's financial condition and profitability with respect to the services it provided the Series. The Boards were also provided with a profitability analysis that detailed the revenues earned and the expenses incurred by BlackRock and certain affiliates that provide services to the Series. The Boards reviewed BlackRock's profitability with respect to the Series and each fund the Boards currently oversee for the year ended December 31, 2007 compared to aggregated profitability data provided for the year ended December 31, 2005. In addition, the Boards considered the cost of the services provided to the Portfolio and the Series by BlackRock, and BlackRock's and its affiliates' profits relating to the management and distribution, as pertinent, of the Portfolio and the Series and the other funds advised by BlackRock and its affiliates. As part of their analysis, the Boards reviewed BlackRock's methodology in allocating its costs to the management of the Portfolio and the Series and concluded that there was a reasonable basis for the allocation. The Boards also considered whether BlackRock has the financial resources necessary to attract and retain high-quality investment management personnel to perform its obligations under the Agreements and to continue to provide the high quality of services that are expected by the Board. The Board noted that the Series paid contractual advisory fees, prior to any expense reimbursements, that were lower than or equal to the median of its Peers. The Board also noted that the actual advisory fees paid were less than the contractual advisory fees, as a result of a contractual arrangement with the Adviser that limits the combined administrative and advisory fees of the Portfolio/Series. BLACKROCK INDEX EQUITY PORTFOLIO JUNE 30, 2008 31 Disclosure of Investment Advisory Agreement and Subadvisory Agreement (concluded) D. Economies of Scale: The Boards, including the Independent Directors, considered the extent to which economies of scale might be realized as the assets of the Portfolio and the Series increase and whether there should be changes in the advisory fee rate or structure in order to enable the Portfolio and the Series to participate in these economies of scale. The Boards, including the Independent Directors, considered whether the shareholders would benefit from economies of scale and whether there was potential for future realization of economies with respect to the Portfolio and the Series. The Boards considered that the funds in the BlackRock fund complex share common resources and, as a result, an increase in the overall size of the complex could permit each fund to incur lower expenses than it would otherwise as a stand-alone entity. The Boards also considered the anticipated efficiencies in the processes of BlackRock's overall operations as it continues to add personnel and commit capital to expand the scale of operations. The Boards found, based on their review of comparable funds, that the Series' management fee is appropriate in light of the scale of the Series. E. Other Factors: The Board also took into account other ancillary or "fall-out" benefits that BlackRock may derive from its relationship with the Portfolio and the Series, both tangible and intangible, such as BlackRock's ability to leverage its investment professionals who manage other portfolios, an increase in BlackRock's profile in the investment advisory community, and the engagement of BlackRock's affiliates as service providers to the Portfolio and the Series, including for administrative, transfer agency and distribution services. The Boards also noted that BlackRock may use third-party research, obtained by soft dollars generated by transactions in the Series, to assist itself in managing all or a number of its other client accounts. In connection with its consideration of the Agreements, the Boards also received information regarding BlackRock's brokerage and soft dollar practices. The Boards received reports from BlackRock which included information on brokerage commissions and trade execution throughout the year. Conclusion The Boards approved the continuation of (a) the Advisory Agreement between the Adviser and the Master LLC with respect to the Series for a one-year term ending June 30, 2009 and (b) the Subadvisory Agreement between the Adviser and the Subadviser with respect to the Series for a one-year term ending June 30, 2009. Based upon their evaluation of all these factors in their totality, the Boards, including the Independent Directors, were satisfied that the terms of the Agreements were fair and reasonable and in the best interest of the Portfolio and the Series and the Portfolio's shareholders. In arriving at a decision to approve the Agreements, the Boards did not identify any single factor or group of factors as all-important or controlling, but considered all factors together. The Independent Directors were also assisted by the advice of independent legal counsel in making this determination. The contractual fee arrangements for the Portfolio and the Series reflect the results of several years of review by the Directors and predecessor Directors, and discussions between the Directors (and predecessor Directors) and BlackRock (and predecessor advisers). Certain aspects of the arrangements may be the subject of more attention in some years than in others, and the Directors' conclusions may be based in part on their consideration of these arrangements in prior years. 32 BLACKROCK INDEX EQUITY PORTFOLIO JUNE 30, 2008 Officers and Directors David O.

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 Series own assumption 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. For information about the Series' policy regarding valuation of investments and other significant accounting policies, please refer to Note 1 of the Notes to Financial Statements. The following table summarizes the inputs used as of June 30, 2008 in determining the fair valuation of the Fund's investments: -------------------------------------------------------------------------- Valuation Investments in Other Financial Inputs Securities Instruments* -------------------------------------------------------------------------- Level 1 $ 3,139,107,064 $ (1,180,717) Level 2 277,807,811 -- Level 3 -- -- -------------------------------------------------------------------------- Total $ 3,416,914,875 $ (1,180,717) ======================================== * Other financial instruments are futures.
