Master Extended Market Index Series

During the period the fund generated net investment income of 0.98% as a
percentage of average net assets.

Contributors and Detractors from Performance:

The portfolio met its objective of replicating the return of its benchmark.
After a negative 1st quarter, the 2nd quarter of 2003 brought impressive gains
and what some are calling a "bull rally." The US markets rose consistently over
the quarter, spurred by optimism that economic and profit growth will
accelerate. On June 16th the S&P 500 closed above the 1,000 mark (at 1,010.74)
for the first time since June 20, 2002. Most indices finished the quarter in
positive territory, with the DJIA closing at 8,985.44, up 993.31 points or
12.43% for the quarter, and the S&P 500 closing at 974.50, 126.32 points or
14.89% for the quarter. The NASDAQ closed at 1,622.80, up 281.63 points or
21.00%, as technology stocks have outperformed the broader market on
expectations that companies in that sector will be among the first beneficiaries
of an economic recovery.

Performance Analysis:

For the 2nd quarter, small and mid-cap stocks proved a better place to be as
they outperformed large-cap stocks, with a 21.45% return for the Wilshire 4500
versus the 16.50% return for the Wilshire 5000.

Markets rallied following the resolution of military affairs in Iraq, investors
have become increasingly bullish about the outlook for equities, and the rise
has been notable for the participation of all sectors and countries.

After the Federal Open Market Committee (FOMC) left rates unchanged at 1.25% at
its May 6th meeting, it lowered its target for the federal funds rate by 25
basis points to 1% at its June 25th meeting, bringing the rate to a 49-year low.
The FOMC continues to use an accommodative stance of monetary policy coupled
with an underlying growth in productivity to provide ongoing support to economic
activity. The modest 25 basis point cut rather than the expected 50 basis point
cut leaves room for further Federal Reserve rate reductions in the future. In
response to the FOMC decision financial markets were initially disappointed,
with long term interest rates backing up sharply and stock prices falling. This
movement will likely be moderated by the realization that the growth outlook
will be strengthened.

Fund Position Going Forward:

Economic indicators for the current economy are ambiguous, but the economy may
strengthen and produce strong results for the second half of 2003. Many of the
geo-political factors that may have exacerbated the slowdown in activity (war
fears, higher oil prices, poor weather and SARS) have been largely resolved.
While the economy is clearly improving, the rate of change is only gradual. Data
indicates that further policy stimulus will hit the economy in the second half
of the year, but it is worth noting the lack of growth given the large cuts in
interest rates already seen. Additionally, a key factor is the concern about
whether consumers will continue to spend long enough to prop up the economy
until a corporate spending cycle emerges.


For the next quarter the reaction of the economy to all the stimuli in the
pipeline and the extent of the recovery is still ambiguous. Lower withholding
taxes from paychecks and child tax credit checks position households on the
receiving end of at least $30 billion from tax relief. This, coupled with a
mortgage-refinancing wave continuing a high incentive to refinance, is
indicative of an increase in consumer spending in the last 6 months of 2003,
putting the economy on a recovery track. With that in mind, the portfolio is
expected to continue to meets its objectives.

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 as a diversified
Series 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 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. These unaudited financial
statements reflect all adjustments, which are, in the opinion of management,
necessary to a fair statement of the results for the interim period presented.
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-- Portfolio securities that are traded on stock
exchanges or the NASDAQ National Market are valued at the last sale price or
official closing price on the exchange on which such securities are traded, 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. Securities traded in the
over-the-counter market are valued at the last available bid price prior to the
time of valuation. In cases where securities are traded on more than one
exchange, the securities are valued on the exchange designated by or under the
authority of the Board of Trustees as the primary market. Portfolio securities
that are traded both in the over-the-counter market and on a stock exchange are
valued according to the broadest and most representative market, and it is
expected that for debt securities this ordinarily will be the over-the-counter
market. Options written or purchased are valued at the last sale price in the
case of exchange-traded options. In the case of options traded in the
over-the-counter market, valuation is the last asked price (options written) or
the last bid price (options purchased). Futures contracts are valued at the
settlement price at the close of the applicable exchange. Short-term securities
are valued at amortized cost, which approximates market value. 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. Occasionally, events affecting the values of securities
and other assets may occur between the times at which valuations of such
securities are determined (that is, close of the market on which such securities
trade) and the close of business on the NYSE. If events (for example, company
announcement, natural disasters, market volatility) occur during such periods
that are expected to materially affect the value for such securities, those
securities may be valued at their fair market value as determined in good faith
by the Trust's Board of Trustees 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.

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

(f) Custodian bank - The Series recorded an amount payable to the custodian bank
reflecting an overnight overdraft, which resulted from an unprojected payment of
net investment income dividends.


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 the expenses incurred by the Series will not exceed .08%. Effective
January 1, 2003, the limit was increased from .08% to .13%. This arrangement
expires December 31, 2003 and is renewable. For the six months ended June 30,
2003, FAM earned fees of $5,009, of which $606 was waived.

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. As of June 30, 2003, the Series lent securities with a value of
$191,211 to MLPF&S 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. For the six
months ended June 30, 2003, MLIM, LLC received $3,061 in securities lending
agent fees from the Series.

In addition, MLPF&S received $1,121 in commissions on the execution of portfolio
security transactions for the Series for the six months ended June 30, 2003.

For the six months ended June 30, 2003, the Series reimbursed FAM $1,064 for
certain accounting services.

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

3. Investments:

Purchases and sales of investments, excluding short-term securities, for the six
months ended June 30, 2003 were $28,105,278 and $12,824,356, respectively.

- -------------------------------------------------------------------------------

As of June 30, 2003, net unrealized depreciation for Federal income tax purposes
aggregated $1,574,400, of which $15,719,890 related to appreciated securities
and $17,294,290 related to depreciated securities. At June 30, 2003, the
aggregate cost of investments for Federal income tax purposes was $126,387,380.


5. 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 Bank One, N.A. and certain other
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
..09% 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 .50% or a
base rate as determined by Bank One, N.A. On November 29, 2002, the credit
agreement was renewed for one year under the same terms, except that the
commitment was reduced from $1,000,000,000 to $500,000,000. The Series did not
borrow under the credit agreement during the six months ended June 30, 2003.
