Master Extended Market Index Series of Quantitative Master Series LLC
Annual Report, December 31, 2007

PORTFOLIO MANAGEMENT COMMENTARY

How did the Series perform?

      o     For the fiscal year ended December 31, 2007, the Extended Market
            Index Series generated returns that were comparable to that of the
            benchmark Wilshire 4500 (Full Cap) Index, as the Series had a total
            return of +5.22% compared to +5.77% for the Index.

      o     The Wilshire 4500 (Full Cap) Index measures the performance of
            stocks in the Wilshire 5000 (Full Cap) Index minus the stocks found
            in the Standard & Poor's 500 (S&P 500(R)) Index. As the value of the
            Wilshire 4500 (Full Cap) Index fluctuated during the past 12 months,
            the portfolio's performance generally tracked that of the Index.

What factors influenced performance?

      o     In total, equity markets performed quite well in 2007. It was a year
            of intense market volatility, but still one that resulted in decent
            gains for most asset classes. Global equity markets benefited from a
            strong first half, which, in most cases, helped to generate positive
            performance for the year as a whole. In the United States, the Dow
            Jones Industrial Average registered a total return of +8.88%.
            Larger-cap stocks noticeably outperformed over the period, as the
            S&P 500 Index advanced 5.49%, while the smaller-cap Russell 2000
            lost 1.57%. Amid strong performance in the technology sector, the
            Nasdaq Composite posted an impressive +9.81% return for the year.

      o     The annual period began much like 2006 ended, with some slowing in
            U.S. economic growth, a Federal Reserve Board (the "Fed") that
            remained on hold and a generally positive investment environment.
            Solid earnings growth and continued high levels of
            merger-and-acquisition activity allowed equities to move upward.

      o     The second half of 2007 was vastly different, however. The benign
            fundamentals that dominated from 2003 to 2006 -- namely, strong
            global growth, rising profitability levels and falling risk premiums
            -- were replaced by credit stress, pressures on the capital position
            of the financial system, question marks about the sustainability of
            the business cycle and rising food and energy prices. Reflecting
            these woes, U.S. government bond yields plummeted, the dollar's
            decline intensified, equities became volatile and trendless, and the
            Fed's focus shifted from inflation fighting to providing liquidity
            and reducing short-term interest rates in an effort to shore up the
            functioning of credit markets and fight economic weakness. Beginning
            in September, the Fed lowered the target federal funds rate by 100
            basis points (1.00%), from 5.25% to 4.25%.

Describe recent portfolio activity.

      o     Throughout the period, as changes were made to the composition of
            the Wilshire 4500 Index, the portfolio 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 portfolio remains
            positioned to match the risk characteristics of its benchmark,
            irrespective of the market's future direction.

Master Extended Market Index Series
Notes to Financial Statements

1. Significant Accounting Policies:

Master Extended Market Index Series (the "Series"), a diversified, open-end
management 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, and is organized as a Delaware limited liability company.
Prior to June 15, 2007, the Master LLC was organized as a Delaware statutory
trust (the "Trust"). The Limited Liability Company Agreement permits the
Directors (and prior to June 15, 2007, the Declaration of Trust permits the
Trustees) to issue non-transferable interests, subject to certain limitations.
Throughout this report, the Trust and the Master LLC are referred to as the
Master LLC and the Board of Trustees of the Trust and the Board of Directors of
the Master LLC are referred to as the Board of Directors. The financial
statements of the Series are prepared in conformity with U.S. generally accepted
accounting principles, which may require the use of management accruals and
estimates. Actual results may differ from these estimates. The following is a
summary of significant accounting policies followed by the Series.

(a) Valuation of investments - Equity securities that are held by the Series
that are traded on stock exchanges or the NASDAQ Global Market are valued at the
last sale price or official close price on the exchange, as of the close of
business on the day the securities are being valued or, lacking any sales, at
the last available bid price for long positions, and at the last available asked
price for short positions. In cases where equity securities are traded on more
than one exchange, the securities are valued on the exchange designated as the
primary market by or under the authority of the Board of Directors. Long
positions traded in the over-the-counter ("OTC") market, NASDAQ Capital Market
or Bulletin Board are valued at the last available bid price or yield equivalent
obtained from one or more dealers or pricing services approved by the Board of
Directors. Short positions traded in the OTC market are valued at the last
available asked price. Portfolio securities that are traded both in the OTC
market and on a stock exchange are valued according to the broadest and most
representative market.

Effective September 4, 2007, exchange-traded options are valued at the mean
between the last bid and ask prices at the close of the options market in which
the options trade and previously were valued at the last sales price as of the
close of options trading on applicable exchanges. Options traded in the OTC
market are valued at the last asked price (options written) or the last bid
price (options purchased). Swap agreements are valued based upon quoted fair
valuations received daily by the Series from a pricing service or counterparty.
Financial futures contracts and options thereon, which are traded on exchanges,
are valued at their last sale price as of the close of such exchanges. Valuation
of short-term investment vehicles is generally based on the net asset value of
the underlying investment vehicle or amortized cost.

Repurchase agreements are valued at cost plus accrued interest. The Series
employs pricing services to provide certain securities prices for the Series.
Securities and assets for which market quotations are not readily available are
valued at fair value as determined in good faith by or under the direction of
the Board of Directors, including valuations furnished by the pricing services
retained by the Master LLC, which may use a matrix system for valuations. The
procedures of a pricing service and its valuations are reviewed by the officers
of the Master LLC under the general supervision of the Board of Directors. Such
valuations and procedures will be reviewed periodically by the Board of
Directors.

Generally, trading in foreign securities, as well as U.S. government securities,
money market instruments and certain fixed income securities is substantially
completed each day at various times prior to the close of business on the New
York Stock Exchange ("NYSE"). The values of such securities used in computing
the net assets of the Series are determined as of such times. Foreign currency
exchange rates will generally be determined as of the close of business on the
NYSE. Occasionally, events affecting the values of such securities and such
exchange rates may occur between the times at which they are determined and the
close of business on the NYSE that may not be reflected in the computation of
the Series' net assets. If events (for example, a company announcement, market

                                       82



volatility or a natural disaster) occur during such periods that are expected to
materially affect the value of such securities, those securities will be valued
at their fair value as determined in good faith by the Board of Directors or by
BlackRock Advisors, LLC (the "Manager"), an indirect, wholly owned subsidiary of
BlackRock, Inc., using a pricing service and/or procedures approved by the Board
of Directors.

(b) Derivative financial instruments - The Series may engage in various
portfolio investment techniques to provide liquidity or as a proxy for a direct
investment in securities underlying the Series' index. Losses may arise due to
changes in the value of the contract due to an unfavorable change in the price
of the underlying security, or index, or if the counterparty does not perform
under the contract. The counterparty, for certain instruments, may pledge cash
or securities as collateral.

      o     Financial futures contracts - The Series may purchase or sell
            financial futures contracts and options on such financial futures
            contracts. Financial futures contracts are contracts for delayed
            delivery of securities at a specific 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 variation margin
            and are recorded 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.

      o     Options - The Series may purchase and write call and put options.
            When the Series writes an option, an amount equal to the premium
            received by the Series is reflected as an asset and an equivalent
            liability. The amount of the liability is subsequently
            marked-to-market to reflect the current market value of the option
            written. When a security is purchased or sold through an exercise of
            an option, the related premium paid (or received) is added to (or
            deducted from) the basis of the security acquired or deducted from
            (or added to) the proceeds of the security sold. When an option
            expires (or the Series enters into a closing transaction), the
            Series realizes a gain or loss on the option to the extent of the
            premiums received or paid (or loss or gain to the extent the cost of
            the closing transaction exceeds the premium paid or received).

            Written and purchased options are non-income producing investments.

(c) 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
provision is required. Under applicable foreign tax laws, a withholding tax may
be imposed on interest, dividends and capital gains at various rates. 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.

(d) Security transactions and investment income - Security 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.

(e) 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. Where the Series receives securities as collateral for
the loaned securities, it collects a fee from the borrower. 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

                                       83



amount earned on such investment, net of any amount rebated to the borrower.
Loans of securities are terminable at any time and the borrower, after notice,
is required to return borrowed securities within five business days. The 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.

(f) Bank overdraft- The Fund recorded a bank overdraft, which resulted from
management estimates of available cash.

(g) Recent accounting pronouncements - Effective June 29, 2007, the Series
implemented Financial Accounting Standards Board ("FASB") Interpretation No. 48,
"Accounting for Uncertainty in Income Taxes -- an interpretation of FASB
Statement No. 109" ("FIN 48"). FIN 48 prescribes the minimum recognition
threshold a tax position must meet in connection with accounting for
uncertainties in income tax positions taken or expected to be taken by an
entity, including investment companies, before being measured and recognized in
the financial statements. Management has evaluated the application of FIN 48 to
the Series, and has determined that the adoption of FIN 48 does not have a
material impact on the Series' financial statements. 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 statute of limitations on the Series' state and local tax
returns may remain open for an additional year depending upon the jurisdiction.

In September 2006, Statement of Financial Accounting Standards No. 157, "Fair
Value Measurements" ("FAS 157"), was issued and is effective for fiscal years
beginning after November 15, 2007. FAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. The impact on the Series' financial statement disclosures, if any,
is currently being assessed.

In addition, in February 2007, Statement of Financial Accounting Standards No.
159, "The Fair Value Option for Financial Assets and Financial Liabilities"
("FAS 159"), was issued and is effective for fiscal years beginning after
November 15, 2007. Early adoption is permitted as of the beginning of a fiscal
year that begins on or before November 15, 2007, provided the entity also elects
to apply the provisions of FAS 157. FAS 159 permits entities to choose to
measure many financial instruments and certain other items at fair value that
are not currently required to be measured at fair value. FAS 159 also
establishes presentation and disclosure requirements designed to facilitate
comparisons between entities that choose different measurement attributes for
similar types of assets and liabilities. The impact on the Series' financial
statement disclosures, if any, is currently being assessed.

2. Investment Advisory Agreement and Transactions with Affiliates:

The Master LLC, on behalf of the Series, has entered into an Investment Advisory
Agreement with the Manager. Merrill Lynch & Co., Inc. ("Merrill Lynch") and The
PNC Financial Services Group, Inc. are the principal owners of BlackRock, Inc.

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 operations of the Series. For such services, the
Series pays a monthly fee at an annual rate of .01% of the average daily value
of the Series' net assets. In addition, the Manager has entered into a
Sub-Advisory Agreement with BlackRock Investment Management, LLC ("BIM"), an
affiliate of the Manager, under which the Manager pays BIM for services it
provides a monthly fee at an annual rate that is a percentage of the management
fee paid by the Series to the Manager.

                                       84



The Master LLC, on behalf of the Series, has received an exemptive order from
the Securities and Exchange Commission permitting the Series to lend its
portfolio securities to Merrill Lynch, Pierce, Fenner & Smith Incorporated
("MLPF&S"), a wholly owned subsidiary of Merrill Lynch, or its affiliates. As of
December 31, 2007, the Series lent securities with a value of $221,120 to MLPF&S
or its affiliates. Pursuant to that order, the Master LLC also 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 Manager or in registered money market
funds advised by the Manager or its affiliates. For the year ended December 31,
2007, BIM received $142,695 in securities lending agent fees.

In addition, MLPF&S received $4,822 in commissions on the execution of portfolio
security transactions for the Series for the year ended December 31, 2007.

For the year ended December 31, 2007, the Series reimbursed the Manager $6,941
for certain accounting services.

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
year ended December 31, 2007 were $119,898,863 and $115,624,397, respectively.

4. Short-Term 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 $500,000,000 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. The Series pays a
commitment fee of .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 .35% or a base rate as defined in the credit agreement. The
Series did not borrow under the credit agreement during the year ended December
31, 2007. On November 21, 2007, the credit agreement renewed for one year under
substantially the same terms.

                                       85

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 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, 2007, by correspondence with the custodian
and brokers; where replies were not received from brokers, we performed other
auditing procedures. We believe that our audits provide a reasonable basis for
our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of Master
Extended Market Index Series of Quantitative Master Series LLC as of December
31, 2007, 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.

1 The nature of the services include assurance and related services reasonably
related to the performance of the audit of financial statements not included in
Audit Fees.

2 The nature of the services include tax compliance, tax advice and tax
planning.

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").



           However, such services will only be deemed pre-approved provided that
           any individual project does not exceed $5,000 attributable to the
           registrant or $50,000 for all of the registrants the Committee
           oversees. Any proposed services exceeding the pre-approved cost
           levels will require specific pre-approval by the Committee, as will
           any other services not subject to general pre-approval (e.g.,
           unanticipated but permissible services). The Committee is informed of
           each service approved subject to general pre-approval at the next
           regularly scheduled in-person board meeting.

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

           (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.
