Master Extended Market Index Series

Annual Report, December 31, 2004

For the year ended December 31, 2004, Master Extended Market Index Series had a
total return of +18.43% (net return, master level). This compared to a return of
+18.56% for the benchmark Dow Jones Wilshire 4500 (Full Cap) Index for the same
period.

As the returns indicate, the portfolio met its objective of closely tracking the
performance of the Dow Jones Wilshire 4500 (Full Cap) Index, which measures the
performance of stocks in the Dow Jones Wilshire 5000 (Full Cap) Index, minus the
stocks found in the Standard & Poor's (S & P) 500 Index. As the value of the Dow
Jones Wilshire 4500 (Full Cap) Index fluctuated during the past 12 months, the
portfolio's performance generally mimicked that of the Index. Throughout the
period, as changes were made to the composition of the Index, the portfolio
purchased and sold securities to maintain its objective of replicating the risks
and return of the benchmark.

Market and Economic Environment

Despite some suspense along the way, 2004 proved to be a positive year for U.S.
equity markets. Economic news was mixed for much of the first three quarters of
the year before turning generally positive in the fourth quarter.

The first quarter was impacted positively by good productivity and gross
domestic product (GDP) numbers, but set back by the railroad bombing in Madrid,
Spain, which caused market volatility to increase substantially. Renewed fears
of terrorist attacks cast the long shadow of geopolitical unrest on equity
markets around the world heading into the second quarter. The aura of


                                       1


uncertainty was exacerbated by such factors as persistent violence in Iraq,
record-high oil prices and mixed, though slowly improving, U.S. economic data.
As the second quarter drew to a close, the drumbeat of presidential election
drama gradually swelled in the United States.

In the third quarter, the course of economic news began to slowly point toward a
strengthening economy. But despite better-than-expected corporate earnings and
Federal Reserve Board (Fed) Chairman Alan Greenspan's congressional testimony
that his outlook on economic growth remained constructive, a number of
challenges hampered the U.S. equity market in the third quarter. Election
buildup, a shifting Fed policy and higher oil prices fanned the flames of fear
that the U.S. economy would slow.

The fourth quarter, however, proved to be the breakout that investors were
looking for in the U.S. equity markets. Negative October news segued into
positive November and December news. As a result of moderating oil prices,
unwinding of the election uncertainty, reasonably good economic and earnings
news, and the beginning of the seasonally strong year-end period, the market
experienced a positive post-election bounce. As expected, the Fed continued to
raise the federal funds rate throughout the year, more than doubling it from 1%
to 2.25% by December 31, 2004.

For the year ended December 31, 2004, the extended market, as measured by the
+18.56% return of the benchmark Dow Jones Wilshire 4500 (Full Cap) Index,
outperformed the broad market, as measured by the +12.62% return of the Dow
Jones Wilshire 5000 (Full Cap) Index.

Small-capitalization and mid-capitalization stocks outpaced large-capitalization
stocks for 2004. For the 12 months ended December 31, 2004, the S&P MidCap 400
Index returned +16.48% and the S&P SmallCap 600 Index returned +22.65%. This
compared to the +10.88% total return of the S&P 500 Index, a generally accepted
measure of large cap stock performance.

Overall, the S&P 500 Index closed the year at 1,211.92 with a price return of
+8.99%. The Dow Jones Industrial Average closed at 10,783.01 with a price return
of +3.15%, while the Nasdaq Composite Index returned +8.59% with a closing level
of 2,175.44. European markets also posted positive returns, with the Financial
Times Stock Exchange 100 Index closing at 4,814.30, representing a return of
+7.54% in sterling. The Morgan Stanley Capital International World Index was up
12.84% in U.S. dollar terms, with a closing level of 1,169.34 at December 31,
2004.

Market Outlook

As 2004 came to an end, the economy and earnings growth were beginning to slow,
the Fed appeared poised to continue moving interest rates higher, legislative
progress was anticipated on many fronts in Washington, and concerns remained
about the structural problems of debt and deficits as reflected by a significant
decline in the U.S. dollar.

The recent increase in equity prices to new cyclical highs has led to questions
about how much upside potential exists. Valuation levels, at least on an
absolute basis, are somewhat stretched, although the profit environment is still
strong enough to support the market. Equity prices could have fallen as a result
of the Fed's December interest rate hike, but clearly have been benefiting from


                                       3


recent declines in bond yields as well as from the declining dollar. Our opinion
is that until monetary tightening and/or rising bond yields begin to take their
toll, equities should continue to perform relatively well. Having said that, we
expect the portfolio to continue to meet its objective of tracking the
performance of the Dow Jones Wilshire 4500 (Full Cap) Index in 2005.

Master Extended Market Index Series

NOTES TO FINANCIAL STATEMENTS

1. Significant Accounting Policies:

Master Extended Market Index Series (the "Series") is part of Quantitative
Master Series Trust (the "Trust"). The Trust is registered under the Investment
Company Act of 1940, as amended, and is organized as a Delaware statutory trust.
The Declaration of Trust permits the Trustees to issue nontransferable interests
in the Series, subject to certain limitations. 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 estimates. All such adjustments are of a normal,
recurring nature. The following is a summary of significant accounting policies
followed by the Series.

(a) Valuation of investments - Equity securities held by the Series that are
traded on stock exchanges or the Nasdaq National Market are valued at the last
sale price or official close price on the exchange, as of the close of business
on the day the securities are being valued or, lacking any sales, at the last
available bid price for long positions, and at the last available ask price for
short positions. In cases where equity securities are traded on more than one
exchange, the securities are valued on the exchange designated as the primary
market by or under the authority of the Board of Trustees of the Trust. Long
positions traded in the over-the-counter ("OTC") market, Nasdaq Small Cap or
Bulletin Board are valued at the last available bid price or yield equivalent
obtained from one or more dealers or pricing services approved by the Board of
Trustees of the Trust. Short positions traded in the OTC market are valued at
the last available ask 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.

Options written are valued at the last sale price in the case of exchange-traded
options or, in the case of options traded in the OTC market, the last ask price.
Options purchased are valued at their last sale price in the case of
exchange-traded options or, in the case of options traded in the OTC market, the
last bid price. Swap agreements are valued daily based upon quotations from
market makers. Financial futures contracts and options thereon, which are traded
on exchanges, are valued at their last sale price as of the close of such
exchanges. Obligations with remaining maturities of 60 days or less are valued
at amortized cost unless the Investment Adviser believes that this method no
longer produces fair valuations.

Repurchase agreements are valued at cost plus accrued interest. The Trust
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 Trustees of the Trust, including valuations furnished by the
pricing services retained by the Trust, which may use a matrix system for
valuations. The procedures of a pricing service and its valuations are reviewed
by the officers of the Trust under the general supervision of the Board of
Trustees of the Trust. Such valuations and procedures will be reviewed
periodically by the Board of Trustees of the Trust.

Generally, trading in foreign securities, as well as U.S. government securities
and money market instruments, 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'
shares are determined as of such times. Foreign currency exchange rates also are
generally determined prior to 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 volatility or a natural
disaster) occur during such periods that are expected to materially affect the
value of such securities, those securities may be valued at their fair value as
determined in good faith by the Board of Trustees of the Trust or by the
Investment Adviser using a pricing service and/or procedures approved by the
Board of Trustees of the Trust.

(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 or if the counterparty does not perform
under the contract.


                                       51


o     Financial futures contracts - The Series may purchase or sell financial
      futures contracts and options on such 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 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.

o     Forward foreign exchange contracts - The Series may enter into forward
      foreign exchange contracts as a hedge against either specific transactions
      or portfolio positions. The contract is marked-to-market daily and the
      change in market value is recorded by the Series as an unrealized gain or
      loss. When the contract is closed, the Series records a realized gain or
      loss equal to the difference between the value at the time it was opened
      and the value at the time it was closed.

o     Foreign currency options and futures - The Series may purchase or sell
      listed or over-the-counter foreign currency options, foreign currency
      futures and related options on foreign currency futures as a short or long
      hedge against possible variations in foreign exchange rates. Such
      transactions may be effected with respect to hedges on non-U.S.
      dollar-denominated securities owned by the Series, sold by the Series but
      not yet delivered, or committed or anticipated to be purchased by the
      Series.

(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 the applicable foreign tax law, 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 receives 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


                                       52


collateral and retain the amount earned on such investment, net of any amount
rebated to the borrower. Loans of securities are terminable at any time and the
borrower, after notice, is required to return borrowed securities within five
business days. The Series may pay reasonable finder's, 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.

2. Investment Advisory Agreement and Transactions with Affiliates:

The Trust has entered into an Investment Advisory Agreement with Fund Asset
Management, L.P. ("FAM"). The general partner of FAM is Princeton Services, Inc.
("PSI"), an indirect, wholly-owned subsidiary of Merrill Lynch & Co., Inc. ("ML
& Co."), which is the limited partner.

FAM 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. FAM has entered into a contractual arrangement with the Series under
which all expenses incurred by the Series will not exceed .12%. This arrangement
has a one-year term and is renewable.

The Trust has received an exemptive order from the Securities and Exchange
Commission permitting it to lend portfolio securities to Merrill Lynch, Pierce,
Fenner & Smith Incorporated ("MLPF&S"), a subsidiary of ML & Co., or its
affiliates. Pursuant to that order, the Trust also has retained Merrill Lynch
Investment Managers, LLC ("MLIM, LLC"), an affiliate of FAM, as the securities
lending agent for a fee based on a share of the returns on investment of cash
collateral. MLIM, LLC may, on behalf of the Trust and the Series, invest cash
collateral received by the Series for such loans, among other things, in a
private investment company managed by MLIM, LLC or in registered money market
funds advised by FAM or its affiliates. As of December 31, 2004, the Series lent
securities with a value of $9,452 to MLPF&S or its affiliates. For the year
ended December 31, 2004, MLIM, LLC received $17,321 in securities lending agent
fees from the Series.

For the year ended December 31, 2004, the Series reimbursed FAM $3,998 for
certain accounting services.

Certain officers and/or trustees of the Series are officers and/or trustees of
FAM, PSI, and/or ML & Co.

3. Investments:

Purchases and sales of investments, excluding short-term securities, for the
year ended December 31, 2004 were $59,809,261 and $40,873,857, respectively.

4. Short-Term Borrowings:

The Series, along with certain other funds managed by FAM 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 .07% 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
Series election, the federal funds rate plus .50% 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, 2004. On November 26, 2004, the credit
agreement was renewed for one year under substantially the same terms.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Investors and Board of Trustees of
Quantitative Master Series Trust:

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Master Extended Market Index Series, one of the
portfolios constituting the Quantitative Master Series Trust (the "Trust") as of
December 31, 2004, 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 respective
periods then ended. These financial statements and financial highlights are the
responsibility of the Trust's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes consideration of internal control over financial reporting as a basis
for designing audit procedures that are appropriate in the circumstances, but
not for the purpose of expressing an opinion on the effectiveness of the Trust's
internal control over financial reporting. Accordingly, we express no such
opinion. An audit also includes examining, on a test basis, evidence supporting
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, 2004, by correspondence with
the custodian. 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 the Quantitative Master Series Trust as of
December 31, 2004, 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 its financial highlights for each of the respective periods then ended, in
conformity with U.S. generally accepted accounting principles.

         and principal accounting officer, or persons performing similar
         functions. A copy of the code of ethics is available without charge

Item 3 - Audit Committee Financial Expert - The registrant's board of directors
         has determined that (i) the registrant has the following audit
         committee financial experts serving on its audit committee and (ii)
         each audit committee financial expert is independent: (1) Donald W.
         Burton, (2) M. Colyer Crum, (3) Laurie Simon Hodrick, (4) John F.
         O'Brien (as of November 22, 2004), (5) David H. Walsh and (6) Fred G.
         Weiss.

         The registrant's board of directors has determined that Laurie Simon
         Hodrick and M. Colyer Crum qualify as financial experts pursuant to
         Item 3(c)(4) of Form N-CSR.

         Ms. Hodrick has a thorough understanding of generally accepted
         accounting principals, financial statements, and internal controls and
         procedures for financial reporting. Ms. Hodrick earned a Ph.D. in
         economics and has taught courses in finance for over 15 years. Her
         M.B.A.-level course centers around the evaluation and analysis of
         firms' corporate financial statements. She has also taught in financial
         analysts' training programs. Ms. Hodrick has also worked with several
         prominent corporations in connection with the analysis of financial
         forecasts and projections and analysis of the financial statements of
         those companies, serving on the Financial Advisory Council of one of
         these major corporations. She has also served as the Treasurer and
         Finance Chair of a 501(c)(3) organization. Ms. Hodrick has published a
         number of articles in leading economic and financial journals and is
         the associate editor of two leading finance journals.

         M. Colyer Crum also possesses a thorough understanding of generally
         accepted accounting principals, financial statements, and internal
         controls and procedures for financial reporting through a combination
         of education and experience. Professor Crum was a professor of
         investment management at the Harvard Business School for 25 years. The
         courses taught by Professor Crum place a heavy emphasis on the analysis
         of underlying company financial statements with respect to stock
         selection and the analysis of credit risk in making loans. Professor
         Crum has also served on a number of boards of directors and has served
         on the audit committees, and in some cases chaired the audit committee,
         for several major corporations and financial institutions. For two such
         organizations, Professor Crum has performed extensive investment
         analysis of financial statements in connection with investment
         management decisions. From these experiences, he has gained significant
         experience with the establishment of reserves and accounting policies,
         differences between U.S. GAAP and Canadian GAAP and executive
         compensation issues.

         (b) Audit-Related Fees - Fiscal Year Ending December 31, 2004 - $0
                                  Fiscal Year Ending December 31, 2003 - $0

         (c) Tax Fees -           Fiscal Year Ending December 31, 2004 - $8,000

         (d) All Other Fees -     Fiscal Year Ending December 31, 2004 - $0
                                  Fiscal Year Ending December 31, 2003 - $0

         (e)(1) 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.

             Fiscal Year Ending December 31, 2003 - $18,621,495

         (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 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.
