2 BLACKROCK SMALL CAP INDEX FUND DECEMBER 31, 2009

Dear Shareholder

In 2009, investors worldwide witnessed a seismic shift in market sentiment as the fear and pessimism that characterized 2008 were replaced by guarded optimism. The single most important reason for this change was the swing from a deep global recession to the beginnings of a global recovery.

At the outset of the year, markets were still reeling from 2008’s nearly unprecedented global financial and economic meltdown. The looming threat of further collapse in global markets prompted stimulus packages and central bank interventions on an extraordinary scale worldwide. Ultimately, these actions helped stabilize the financial system, and the economic contraction began to abate.

Stocks fell sharply to start 2009 as investor confidence remained low on fears of an economic depression. After touching their lows in March, stocks galloped higher as massive, coordinated global monetary and fiscal stimulus began to reflate world economies. Sidelined cash poured into the markets, triggering a dramatic and steep upward rerating of stocks and other risk assets. The financial sector and low-quality securities that had been battered most in the downturn enjoyed the sharpest recovery. The experience in international markets was similar to that seen in the United States. European stocks slightly edged out other developed markets for the year, but emerging markets were the clear winners in 2009. To some extent, this outperformance reflected the stronger recoveries in emerging economies and corporate earnings, but emerging market stocks also saw significant expansion in valuations.

The improvement in the economic backdrop was reflected in fixed income markets as well, where non-Treasury assets made a robust recovery. One of the major themes for 2009 was the reversal of the flight-to-quality trade seen in 2008. As investors grew more comfortable with risk, high yield finished the year as the strongest-performing fixed income sector in both the taxable and tax-exempt space. Overall, the municipal market made a strong showing, outpacing most taxable sectors. Despite fundamental challenges, the technical picture remained supportive of the asset class. Municipal fund inflows had a record-setting year; investor expectations of higher taxes boosted demand; and the Build America Bonds program was deemed a success, adding $65 billion of taxable supply to the municipal marketplace in 2009. Notably, the program has alleviated tax-exempt supply pressure and attracted the attention of a global audience.

All told, the rebound in sentiment and global market conditions propelled virtually every major benchmark index into positive territory for both the 6- and 12-month periods, with the notable exception of Treasury bonds, which were negatively affected by rising long-term rates.

Fund Summary as of December 31, 2009 BlackRock Small Cap Index Fund

Portfolio Management Commentary
	How did the Fund perform?
•	Through the Fund’s investment in Master Small Cap Index Series (the “Series”) of Quantitative Master Series LLC (the “Master LLC”), the Fund’s Institutional and Investor A Shares generated returns of 26.67% and 26.36%, respectively, for the 12 months ended December 31, 2009, underperforming its benchmark, the Russell 2000 Index, which returned 27.17%. The Russell 2000 Index is a market-weighted index composed of approximately 2,000 common stocks issued by small-capitalization US companies in a range of businesses.
•	Returns for the Fund’s share classes differ from the benchmark based on individual share-class expenses.
	Describe the market environment.
•	Following a very difficult 2008, during which the world experienced an unprecedented global financial and economic meltdown, stocks entered 2009 by falling another 35% in the United States as fears of depression and financial system nationalization gripped investors. From the March 2009 lows, stocks galloped higher as those fears dissipated and massive global monetary and fiscal stimuli began to re-inflate economic activity. We have described it as a tug of war between the forces of debt-induced deflation and those of policy-induced reflation. While deleveraging and other deflationary forces did not leave the scene, consistent and aggressive policy ignited the reflationary process. 2009 produced negative real economic growth, weak nominal growth and significant earnings declines. Despite that backdrop, “risk” assets outperformed “safe” assets as cash on the sidelines (which was producing near-zero returns) moved back into the markets. Emerging markets handily beat developed markets. Inflation fell in most countries and widespread deflation was avoided. Treasury rates moved modestly higher as the yield curve steepened. Quality spreads narrowed, but ended the year with sharp gains. Financial stocks and low-quality securities led the way back, and materials was the standout sector performer. Government spending reached record proportions, and the year ended with cyclical stimulus leading the way while at the same time masking the structural problems that remain.
•	On a total return basis, the Dow Jones Industrial Average gained 22.68%; the S&P 500 rose 26.46%; and the Nasdaq Composite advanced 45.32% (helped in large part by the exceptional performance of the technology sector). Small-cap stocks experienced similarly strong gains for the year, with the Russell 2000 Index climbing 27.17%.
•	Within the benchmark Russell 2000 Index, nine of the ten sectors posted positive returns for the period. Materials, consumer discretionary and information technology emerged as the best performers, while financials was the only sector to post a negative return.
	Describe recent portfolio activity.
•	Throughout the 12-month period, as changes were made to the composition of the Russell 2000 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.
•	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. These views are not intended to be a forecast of future events and are no guarantee of future results.

Derivative Financial Instruments

The Series may invest in various derivative instruments, including financial futures contracts, as specified in Note 2 of the Notes to Financial Statements, which constitute forms of economic leverage. Such instruments are used to obtain exposure to a market without owning or taking physical custody of securities or to hedge market and/or equity risks. Such derivative instruments involve risks, including the imperfect correlation between the value of a derivative instrument and the underlying asset, possible default of the counterparty to the transaction or illiquidity of the derivative instrument. The Series’ ability to successfully use a derivative instrument depends on the investment advisor’s ability to accurately predict pertinent market movements, which cannot be assured. The use of derivative instruments may result in losses greater than if they had not been used, may require the Series to sell or purchase portfolio securities at inopportune times or for distressed values, may limit the amount of appreciation the Series can realize on an investment or may cause the Series to hold a security that it might otherwise sell. The Series’ investments in these instruments are discussed in detail in the Notes to Financial Statements.

About Fund Performance

•	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.
•	Investor A Shares are not subject to any sales charge and bear no ongoing distribution fee. Investor A Shares are subject to an ongoing service fee of 0.25% per year.
	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. Figures shown in the performance tables on page 5 assume reinvestment of all dividends and capital gain distributions, if any, at net asset value on the ex-dividend date. Investment return and principal value of shares will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. Dividends paid to each class of shares will vary because of the different levels of service and transfer agency fees applicable to each class, which are deducted from the income available to be paid to shareholders.

Disclosure of Expenses

Shareholders of this Fund may incur the following charges: (a) expenses related to transactions, redemption fees and exchange fees; and (b) operating expenses including advisory fees, service and distribution fees including 12b-1 fees and other Fund expenses. The expense example shown below (which is based on a hypothetical investment of $1,000 invested on July 1, 2009 and held through December 31, 2009) is intended to assist shareholders both in calculating expenses based on an investment in the Fund and in comparing these expenses with similar costs of investing in other mutual funds.

The table provides information about actual account values and actual expenses. In order to estimate the expenses a shareholder paid during the period covered by this report, shareholders can divide their account value by $1,000 and then multiply the result by the number corresponding to their share class under the heading entitled “Expenses Paid During the Period.”

The table also provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses. In order to assist shareholders in comparing the ongoing expenses of investing in this Fund and other funds, compare the 5% hypothetical example with the 5% hypothetical examples that appear in other funds’ shareholder reports.

The expenses shown in the table are intended to highlight shareholders’ ongoing costs only and do not reflect any transactional expenses, such as sales charges, redemption fees or exchange fees. Therefore, the hypothetical example 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.

Expense Example

	Actual						Hypothetical2
	Beginning Account Value July 1, 2009		Ending Account Value December 31, 2009		Expenses Paid During the Period1		Beginning Account Value July 1, 2009		Ending Account Value December 31, 2009		Expenses Paid During the Period1
Institutional	$	1,000	$	1,236.20	$	3.04	$	1,000	$	1,022.48	$	2.75
Investor A	$	1,000	$	1,234.80	$	4.51	$	1,000	$	1,021.17	$	4.08

1

For each class of the Fund, expenses are equal to the annualized expense ratio for the class (0.54% for Institutional and 0.80% for Investor A), multiplied by the average account value over the period, multiplied by 184/365 (to reflect the one-half year period shown). Because the Fund is a feeder fund, the expense table example reflects the expenses of both the feeder fund and the master portfolio 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 half year divided by 365.

Notes to Financial Statements BlackRock Small Cap Index Fund

1. Organization and Significant Accounting Policies:

BlackRock Small Cap Index Fund (the “Fund”), a series of BlackRock Index Funds, Inc. (the “Corporation”), is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as a non-diversified, open-end management investment company. The Corporation is organized as a Maryland corporation. The Fund seeks to achieve its investment objective by investing all of its assets in Master Small Cap Index Series (the “Series”) of Quantitative Master Series LLC (the “Master LLC”), which has the same investment objective and strategies as the Fund. The value of the Fund’s investment in the Series reflects the Fund’s proportionate interest in the net assets of the Series. The performance of the Fund is directly affected by the performance of the Series. The percentage of the Series owned by the Fund at December 31, 2009 was 41%. 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 Fund’s financial statements. The Fund’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 Fund offers two classes of shares. Institutional and Investor A Shares are generally sold without the imposition of a front-end or deferred sales charge. Both classes of shares have identical voting, dividend, liquidation and other rights and the same terms and conditions, except that Investor A Shares bear certain expenses related to the shareholder servicing of such shares and have exclusive voting rights with respect to matters relating to its shareholder servicing expenditures.

The following is a summary of significant accounting policies followed by the Fund:

Valuation: The Fund 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.

Fair Value Measurements: Various inputs are used in determining the fair value of investments, which are as follows:

• Level 1 — price quotations in active markets/exchanges for identical assets and liabilities

• Level 2 — other observable inputs (including, but not limited to: quoted prices for similar assets or liabilities in markets that are active, quoted prices for identical or 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)

• Level 3 — unobservable inputs based on the best information available in the circumstances, 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.

As of December 31, 2009, the Fund’s investment in the Series was classified as Level 2. More relevant disclosure regarding fair value measurements relating to the Series which is disclosed in the Series’ Summary Schedule of Investments included elsewhere in this report.

Investment Transactions and Investment Income: For financial reporting purposes, investment transactions in the Series are accounted for on a trade date basis. The Fund records daily its proportionate share of the Series’ income, expenses and realized and unrealized gains and losses. In addition, the Fund accrues its own expenses. Income, 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 Fund are recorded on the ex-dividend dates.

Income Taxes: It is the Fund’s policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its taxable income to its shareholders. Therefore, no federal income tax provision is required.

The Fund files US federal and various state and local tax returns. No income tax returns are currently under examination. The statute of limitations on the Fund’s US federal tax returns remains open for each of the four years ended December 31, 2009. The statutes of limitations on the Fund’s state and local tax returns may remain open for an additional year depending upon the jurisdiction.

Recent Accounting Standards: In June 2009, amended guidance was issued by the Financial Accounting Standards Board (“FASB”) for transfers of financial assets. This guidance is intended to improve the relevance, representational faithfulness and comparability of the information that a reporting entity provides in its financial statements about a transfer of financial assets; the effects of a transfer on its financial position, financial performance, and cash flows; and a transferor’s continuing involvement, if any, in transferred financial assets. The amended guidance is effective for financial statements for fiscal years and interim periods beginning after November 15, 2009. Earlier application is prohibited. The recognition and measurement provisions of this guidance must be applied to transfers occurring on or after the effective date. Additionally, the enhanced disclosure provisions of the amended guidance should be applied to transfers

Notes to Financial Statements (continued) BlackRock Small Cap Index Fund

that occurred both before and after the effective date of this guidance. The impact of this guidance on the Fund’s financial statements and disclosures, if any, is currently being assessed.

In January 2010, the FASB issued amended guidance for improving disclosure about fair value measurements that adds new disclosure requirements about transfers into and out of Levels 1 and 2 and separate disclosures about purchases, sales, issuances and settlements in the reconciliation for fair value measurements using significant unobservable inputs (Level 3). It also clarifies existing disclosure requirements relating to the levels of disaggregation for fair value measurement and inputs and valuation techniques used to measure fair value. The amended guidance is effective for financial statements for fiscal years and interim periods beginning after December 15, 2009 except for disclosures about purchases, sales, issuances and settlements in the rollforward of activity in Level 3 fair value measurements, which are effective for fiscal years beginning after December 15, 2010 and for interim periods within those fiscal years. The impact of this guidance on the Fund’s financial statements and disclosures, if any, is currently being assessed.

Other: Expenses directly related to the Fund or its classes are charged to that Fund 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 Fund are allocated daily to each class based on its relative net assets.

2. Administration Agreement and Other Transactions with Affiliates:

The PNC Financial Services Group, Inc. (“PNC”), Bank of America Corporation (“BAC”) and Barclays Bank PLC (“Barclays”) are the largest stockholders of BlackRock, Inc. (“BlackRock”). Due to the ownership structure, PNC is an affiliate for 1940 Act purposes, but BAC and Barclays are not.

The Corporation, on behalf of the Fund, has entered into an Administration Agreement with BlackRock Advisors, LLC (the “Administrator”), an indirect, wholly owned subsidiary of BlackRock, to provide administrative services (other than investment advice and related portfolio activities) necessary for the operation of the Fund. For such services, the Fund pays the Administrator a monthly fee at an annual rate of 0.29% of the Fund’s average daily net assets.

The Administrator has entered into a voluntary arrangement with the Fund under which the annual operating expenses (after contractual fee waivers) incurred by each class of shares of the Fund (excluding service fees) will not exceed 0.60% for Institutional Shares and 0.85% for Investor A Shares. This arrangement has a one-year term and is renewable. This amount is shown as fees waived by administrator in the Statement of Operations.

The Corporation, on behalf of the Fund, has entered into a Distribution Agreement and Distribution Plan with BlackRock Investments, LLC (“BRIL”), which is an affiliate of BlackRock.

Pursuant to the Distribution Plans adopted by the Corporation in accordance with Rule 12b-1 under the 1940 Act, the Fund pays BRIL an ongoing service fee with respect to Investor A Shares. The fee is accrued daily and paid monthly at an annual rate of 0.25% based upon the average daily net assets of Investor A Shares.

Pursuant to sub-agreements with BRIL, broker-dealers and BRIL provide shareholder servicing to the Fund. The ongoing service fee compensates BRIL and each broker-dealer for providing shareholder servicing to Investor A shareholders.

PNC Global Investment Servicing (U.S.) Inc., an indirect, wholly owned subsidiary of PNC and an affiliate of the Administrator, serves as transfer agent and dividend disbursing agent. Each class of the Fund bears the costs of transfer agent fees associated with such respective class. Transfer agency fees borne by each class of the Fund are comprised of those fees charged for all shareholder communications including mailing of shareholder reports, dividend and distribution notices, and proxy materials for shareholder 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, 12b-1 fee calculation, check writing, anti-money laundering services, and customer identification services.

Pursuant to written agreements, certain affiliates provide the Fund with sub-accounting, recordkeeping, sub-transfer agency and other administrative services with respect to sub-accounts they service. For these services, these affiliates receive an annual fee per shareholder account which will vary depending on share class. For the year ended December 31, 2009, the Fund paid $5,835 in return for these services, which are included in transfer agent in the Statement of Operations.

The Administrator maintains a call center, which is responsible for providing certain shareholder services to the Fund, such as responding to shareholder inquiries and processing transactions based upon instructions from shareholders with respect to the subscription and redemption of Fund shares. For the year ended December 31, 2009, the Fund reimbursed the Administrator for costs incurred running the call center, which are included in the transfer agent in the Statement of Operations.

	Call Center Fees
Institutional		$	367
Investor A		$	1,056

Certain officers and/or directors of the Corporation are officers and/or directors of BlackRock or its affiliates. The Fund reimburses the Administrator for compensation paid to the Corporation’s Chief Compliance Officer.

3. Income Tax Information:

Reclassifications: Accounting principles generally accepted in the United States of America require that certain components of net assets be adjusted to reflect permanent differences between financial and tax reporting. These reclassifications have no effect on net assets or net asset values per share. The following permanent differences as of December 31, 2009 attributable to the sale of stock of passive foreign investment companies, the classification of settlement proceeds and in-kind withdrawals were reclassified to the following accounts:

Undistributed net investment income	$	6,669
Accumulated net realized loss allocated from Series	$	(13,179,619	)
Paid-in capital	$	13,172,950

The tax character of distributions paid during the fiscal years ended December 31, 2009 and 2008 was as follows:

	12/31/09		12/31/08
Distributions paid from:
Ordinary income	$	551,654	$	1,680,670
Long-term capital gains		—		8,947,999
Tax return of capital		—		1,032,666
Total distributions	$	551,654	$	11,661,335

As of December 31, 2009 the tax components of accumulated net losses were as follows:

Undistributed ordinary income	$	39,363
Capital loss carryforwards		(24,323,969	)
Net unrealized gains*		884,477
Total	$	(23,400,129	)

* The differences between book-basis and tax-basis net unrealized gains were attributable primarily to the tax deferral of losses on wash sales, the realization for tax purposes of unrealized gains on investments in passive foreign investment companies, the treatment of certain security lending transactions, the realization for tax purposes of unrealized gains/(losses) on certain futures contracts, the classification of settlement proceeds and other temporary differences.

As of December 31, 2009, the Fund had capital loss carryforwards in the amount of $24,323,969 available to offset future realized capital gains, which expires December 31, 2017.

4. Capital Share Transactions:

We have audited the accompanying statement of assets and liabilities, of BlackRock Small Cap Index Fund, one of the series constituting BlackRock Index Funds, Inc., (the “Fund”) as of December 31, 2009, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of BlackRock Small Cap Index Fund of BlackRock Index Funds, Inc. as of December 31, 2009, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

BLACKROCK SMALL CAP INDEX FUND DECEMBER 31, 2009 25

Notes to Financial Statements Master Small Cap Index Series

1. Organization and Significant Accounting Policies:

Master Small Cap Index Series (the “Series”), a non-diversified, open-end management investment company, is a series of Quantitative Master Series LLC (the “Master LLC”). The Master LLC is registered as an investment company under the Investment Company Act of 1940, as amended (the “1940 Act”), and is organized as a Delaware limited liability company. The Master LLC’s Limited Liability Company Agreement permits the Board of Directors (the “Board”) to issue nontransferable interests, 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: The Series’ policy is to value instruments at fair value. 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 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 traded on exchanges are valued at their last sale price. Investments in open-end investment companies are valued at net asset value each business day. Short-term securities with maturities less than 60 days may be valued at amortized cost, which approximates fair value.

The Series values its investment in BlackRock Liquidity Series, LLC Money Market Series (the “Money Market Series”) at fair value, which is ordinarily based upon its pro rata ownership in the net assets of the underlying fund. The Money Market Series seeks current income consistent with maintaining liquidity and preserving capital. The Money Market Series’ investments will follow the parameters of investments by a money market fund that is subject to Rule 2a-7 promulgated by the Securities and Exchange Commission (“SEC”) under the 1940 Act. The Series may withdraw up to 25% of its investment daily, although the manager of the Money Market Series, in its sole discretion, may permit an investor to withdraw more than 25% on any one 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, or is not available, 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 Series 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.

Segregation and Collateralization: In cases in which the 1940 Act and the interpretive positions of the SEC require that the Series either delivers collateral or segregates assets in connection with certain investments (e.g., financial futures contracts), the Series will, consistent with SEC rules and/or certain interpretive letters issued by the SEC, segregate collateral or designate on its books and records cash or other liquid securities having a market value at least equal to the amount that would otherwise be required to be physically segregated. Furthermore, based on requirements and agreements with certain exchanges and third party broker-dealers, each party has requirements to deliver/deposit securities as collateral for certain investments.

Investment Transactions and Investment Income: For financial reporting purposes, investment transactions are recorded on the dates the transactions are entered into (the trade dates). Realized gains and losses on investment transactions are determined on the identified cost basis. Dividend income is recorded on the ex-dividend dates. Upon notification from issuers, some of the dividend income received from a real estate investment trust may be redesignated as a reduction of cost of the related investment and/or realized gain. Interest income is recognized on the accrual basis.

Securities Lending: The Series may lend securities to financial institutions that provide cash 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 income on the loaned securities but does not receive the income on the collateral. The Series may invest the cash 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 if the value of an investment purchased with cash collateral falls below the market value of loaned securities or if the value of an investment purchased with cash collateral falls below the original value of the cash collateral received.

Income Taxes: The Series is classified as a partnership 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

26 BLACKROCK SMALL CAP INDEX FUND DECEMBER 31, 2009

Notes to Financial Statements (continued) Master Small Cap Index Series

provision is required. It is intended that the Master LLC’s assets will be managed so an investor in the Master LLC can satisfy the requirements of Subchapter M of the Internal Revenue Code. Under applicable foreign tax laws, a withholding tax may be imposed on interest, dividends and capital gains at various rates.

The Series files US federal and various state and local tax returns. No income tax returns are currently under examination. The statute of limitations on the Series’ US federal tax returns remain open for each of the four years ended December 31, 2009. The statute of limitations on the Series’ state and local tax returns may remain open for an additional year depending upon the jurisdiction.

Recent Accounting Standards: In June 2009, amended guidance was issued by the Financial Accounting Standards Board (“FASB”) for transfers of financial assets. This guidance is intended to improve the relevance, representational faithfulness and comparability of the information that a reporting entity provides in its financial statements about a transfer of financial assets; the effects of a transfer on its financial position, financial performance, and cash flows; and a transferor’s continuing involvement, if any, in transferred financial assets. The amended guidance is effective for financial statements for fiscal years and interim periods beginning after November 15, 2009. Earlier application is prohibited. The recognition and measurement provisions of this guidance must be applied to transfers occurring on or after the effective date. Additionally, the enhanced disclosure provisions of the amended guidance should be applied to transfers that occurred both before and after the effective date of this guidance. The impact of this guidance on the Series’ financial statements and disclosures, if any, is currently being assessed.

In January 2010, the FASB issued amended guidance for improving disclosure about fair value measurements that adds new disclosure requirements about transfers into and out of Levels 1 and 2 and separate disclosures about purchases, sales, issuances and settlements in the reconciliation for fair value measurements using significant unobservable inputs (Level 3). It also clarifies existing disclosure requirements relating to the levels of disaggregation for fair value measurement and inputs and valuation techniques used to measure fair value. The amended guidance is effective for financial statements for fiscal years and interim periods beginning after December 15, 2009 except for disclosures about purchases, sales, issuances and settlements in the rollforward of activity in Level 3 fair value measurements, which are effective for fiscal years beginning after December 15, 2010 and for interim periods within those fiscal years. The impact of this guidance on the Series’ financial statements and 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. Derivative Financial Instruments:

The Series may engage in various portfolio investment strategies both to increase the returns of the Series and to economically hedge, or protect, its exposure to certain risks, such as equity risk. Losses may arise if the value of the contract decreases due to an unfavorable change in the price of the underlying instruments or if the counterparty does not perform under the contract. To the extent amounts due to the Series from its counterparty are not fully collateralized contractually or otherwise, the Series bears the risk of loss from counterparty non-performance. See Note 1 “Segregation and Collateralization” for information with respect to collateral practices. Counterparty risk related to exchange-traded financial futures contracts and options is minimal because of the protection against defaults provided by the exchange on which they trade.

Financial Futures Contracts: The Series may purchase or sell financial futures contracts and options on financial futures contracts to gain exposure to, or economically hedge against, changes in the value of equity securities (equity risk). Financial futures contracts are contracts for delayed delivery of securities at a specific future date and at a specific price or yield. 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. The use of financial futures transactions involves the risk of an imperfect correlation in the movements in the price of financial futures contracts, interest rates and the underlying assets.

3. Investment Advisory Agreement and Other Transactions with Affiliates:

The PNC Financial Services Group, Inc. (“PNC”), Bank of America Corporation (“BAC”) and Barclays Bank PLC (“Barclays”) are the largest stockholders of BlackRock, Inc. (“BlackRock”). Due to the ownership structure, PNC is an affiliate for 1940 Act purposes, but BAC and Barclays are not.

The Master LLC, on behalf of the Series, entered into an Investment Advisory Agreement with BlackRock Advisors, LLC (the “Manager”), the Series’ investment advisor, an indirect, wholly owned subsidiary of BlackRock, to provide investment advisory and administration services.

The Manager is responsible for the management of the Series’ portfolio and provides the necessary personnel, facilities, equipment and certain other services necessary to the operation of the Series. For such services, the Series pays the Manager a monthly fee at an annual rate of 0.01% of the average daily value of the Series’ net assets.

The Manager has entered into a contract with the Master LLC, on behalf of the Series, that provides that the advisory fee for the Series, when combined with the administration fees of a certain feeder fund, will not exceed a specified amount. No fees are currently being waived for the Series. This arrangement has a one-year term and is renewable.

The Manager has entered into a contractual arrangement with the Master LLC with respect to the Series under which the Manager will waive its fees or reimburse expenses so that the total operating expenses incurred by the Series will not exceed 0.08% of the Series’ average daily net assets. This arrangement has a one-year term and is renewable. For the year ended December 31, 2009, the Manager waived $55,314, which is included in fees waived by advisor in the Statement of Operations.

The Manager has agreed to waive its advisory fee by the amount of investment advisory fees the Series pays to the Manager indirectly through is investment in affiliated money market funds. For the year ended December 31, 2009, the Manager waived advisory fees in the amount of $5,072, which is included in fees waived by advisor in the Statement of Operations.

The Manager has entered into a separate sub-advisory agreement with BlackRock Investment Management, LLC (“BIM”), an affiliate of the Manager, under which the Manager pays the sub-advisor for services it provides, a monthly fee that is a percentage of the investment advisory fee paid by the Series to the Manager.

For the year ended December 31, 2009, the Series reimbursed the Manager $6,369 for certain accounting services, which is 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, among other things, to pay an affiliated securities lending agent a fee based on a share of the income derived from the securities lending activities and has retained BIM as the securities lending agent. BIM may, on behalf of the Master LLC and the Series, invest cash collateral received by the Series for such loans, among other things, in a private investment company managed by the Manager or in registered money market funds advised by the Manager or its affiliates. The share of income earned by the Series on such investments is shown as securities lending — affiliated in the Statement of Operations. For the year ended December 31, 2009, BIM received $110,435 in securities lending agent fees.

Certain officers and/or directors of the Master LLC are officers and/or directors of BlackRock or its affiliates.

5. Borrowings:

The Master LLC, on behalf of the Series, along with certain other funds managed by the Manager and its affiliates, is a party to a $500 million credit agreement with a group of lenders, which was renewed until November 2010. 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. Prior to its renewal, the credit agreement had the following terms: 0.02% upfront fee on the aggregate commitment amount which was allocated to the Series based on its net assets as of October 31, 2008; a commitment fee of 0.08% per annum based on the Series’ pro rata share of the unused portion of the credit agreement, which is included in miscellaneous in the Statement of Operations, and interest at a rate equal to the higher of the (a) federal funds effective rate and (b) reserve adjusted one-month LIBOR, plus, in each case, the higher of (i) 1.50% and (ii) 50% of the CDX Index (as defined in the credit agreement) on amounts borrowed. Effective November 2009, the credit agreement was renewed with the following terms: 0.02% upfront fee on the aggregate commitment amount which was allocated to the Series based on its net assets as of October 31, 2009, a commitment fee of 0.10% per annum based on the Series’ pro

Notes to Financial Statements (concluded) Master Small Cap Index Series

rata share of the unused portion of the credit agreement and interest at a rate equal to the higher of (a) the one-month LIBOR plus 1.25% per annum and (b) the Fed Funds rate plus 1.25% per annum on amounts borrowed. The Series did not borrow under the credit agreement during the year ended December 31, 2009.

6. Concentration, Market and Credit Risk:

In the normal course of business, the Series invests in securities and enters into transactions where risks exist due to fluctuations in the market (market risk) or failure of the issuer of a security to meet all its obligations (credit risk). The value of securities held by the Series may decline in response to certain events, including those directly involving the issuers whose securities are owned by the Series; conditions affecting the general economy; overall market changes; local, regional or global political, social or economic instability; and currency and interest rate and price fluctuations. Similar to credit risk, the Series may be exposed to counterparty risk, or the risk that an entity with which the Series has unsettled or open transactions may default. Financial assets, which potentially expose the Series to credit and counterparty risks, consist principally of investments and cash due from counterparties. The extent of the Series’ exposure to credit and counterparty risks with respect to these financial assets is generally approximated by their value recorded in the Series’ Statement of Assets and Liabilities, less any collateral held by the Series.

The Series invests a significant portion of its assets in the financial services sector. Changes in economic conditions affecting the financial services sector would have a greater impact on the Series, and could affect the value, income and/or liquidity of positions in such securities.

7. Subsequent Events:

Management has evaluated the impact of all subsequent events on the Series through February 24, 2010, the date the financial statements were issued, and has determined that there were no subsequent events requiring adjustment or additional disclosure in the financial statements.

Report of Independent Registered Public Accounting Firm Master Small Cap Index Series

To the Investors and Board of Directors of Quantitative Master Series LLC:

We have audited the accompanying statement of assets and liabilities, including the summary schedule of investments, of Master Small Cap Index Series, one of the portfolios constituting Quantitative Master Series LLC, (the “Master LLC”) as of December 31, 2009, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Master LLC’s management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Master LLC is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Master LLC’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2009, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Master Small Cap Index Series of Quantitative Master Series LLC as of December 31, 2009, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

3 The nature of the services include a review of compliance procedures and attestation thereto.

(e)(1) Audit Committee Pre-Approval Policies and Procedures:

          The registrant’s audit committee (the “Committee”) has adopted policies and procedures with regard to the pre-approval of services. Audit, audit-related and tax compliance services provided to the registrant on an annual basis require specific pre-approval by the Committee. The Committee also must approve other non-audit services provided to the registrant and those non-audit services provided to the registrant’s affiliated service providers that relate directly to the operations and the financial reporting of the registrant. Certain of these non-audit services that the Committee believes are a) consistent with the SEC’s auditor independence rules and b) routine and recurring services that will not impair the independence of the independent accountants may be approved by the Committee without consideration on a specific case-by-case basis (“general pre-approval”). The term of any general pre-approval is 12 months from the date of the pre-approval, unless the Committee provides for a different period. Tax or other non-audit services provided to the registrant which have a direct impact on the operation or financial reporting of the registrant will only be deemed pre-approved provided that any individual project does not exceed $10,000 attributable to the registrant or $50,000 for all of the registrants the Committee oversees. For this purpose, multiple projects will be aggregated to determine if they exceed the previously mentioned cost levels.

          Any proposed services exceeding the pre-approved cost levels will require specific pre-approval by the Committee, as will any other services not subject to general pre-approval (e.g., unanticipated but permissible services). The Committee is informed of each service approved subject to general pre-approval at the next regularly scheduled in-person board meeting. At this meeting, an analysis of such services is presented to the Committee for ratification. The Committee may delegate to one or more of its members the authority to approve the provision of and fees for any specific engagement of permitted non-audit services, including services exceeding pre-approved cost levels.

(e)(2) None of the services described in each of Items 4(b) through (d) were approved by the audit committee pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

(f) Not Applicable

(g) Affiliates’ Aggregate Non-Audit Fees:

Master Small Cap Index Series of Quantitative Master Series LLC	$424,500	$422,000

	(h) The registrant’s audit committee has considered and determined that the provision of non-audit services that were rendered to the registrant’s investment adviser (not including any non-affiliated sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by the registrant’s investment adviser), and any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the registrant that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible with maintaining the principal accountant’s independence.
