DEAR SHAREHOLDER

Fiscal Year in Review

For the year ended December 31, 2002, Merrill Lynch Small Cap Index Fund's Class
A and Class D Shares had total returns of -20.61% and -20.75%, respectively,
while the Russell 2000 Index posted a total return of -20.48%. (Complete
performance information can be found on pages 3 and 4 of this report to
shareholders.) In 2002, value outperformed growth with the Russell 2000 Value
Index posting a total return of -11.43% compared to a total return of -30.26%
for the unmanaged Russell 2000 Growth Index.

Ten of the 12 Russell sectors posted negative returns in 2002, further evidence
that the decline over the year was across the whole market, although some
sectors negatively affected performance more than others. The technology sector,
which entered the bear market in early 2000, continued to contribute to the
decline in 2002, with technology posting the worst return for the year at
- -46.54%. Sectors most resilient to the market decline were financial services at
+2.11% and integrated oils at +1.04%.

The first quarter of 2002 was quiet and uneventful relative to the rest of the
year. Extreme market volatility took a turn for the worse in the second quarter.
The excessive volatility was mainly a result of the successive failure of
high-profile companies and increased concerns about accounting standards.
Although U.S. markets experienced three weeks of consecutive gains in August,
the markets lost ground for the next five following weeks and closed with
negative returns for the third quarter. A significant rebound was seen among
large cap stocks in the fourth quarter with the Standard & Poor's 500 (S&P 500)
Index closing up 64.54 points at 879.82, with a total return of +8.44% for the
fourth quarter of 2002. The Russell 2000 Index also reached positive territory,
returning +6.16% in the fourth quarter. Better-than-estimated corporate earnings
reports and the belief that corporate earnings had bottomed spurned an
improvement in market conditions. The impressive fourth-quarter rally can also
be partially attributed to the promise of fiscal stimulus from the Federal
Reserve Board's lowering of interest rates late in 2002.

After cutting interest rates 11 consecutive times in 2001, the Federal Reserve
Board left interest rates unchanged at 1.75% until the fourth quarter of 2002.
At the November 6, 2002 Federal Open Market Committee meeting, the Federal
Reserve Board decided to lower its target rate by an unexpected 50 basis points
(.50%) to 1.25%. Economic data indicated that greater uncertainty, in part
attributable to heightened geopolitical risks, was inhibiting spending,
production and employment. In November 2002, the Governing Council of the
European Central Bank declined to match the half-point interest rate reduction
by the Federal Reserve Board and left its rate unchanged at 3.25%. However, at
its December 5 meeting, the European Central Bank cut interest rates by 50 basis
points to 2.75%, reflecting the persistently high degree of uncertainty. Over
time, the current accommodative stance of monetary policy, coupled with still
robust underlying growth in productivity, should be sufficient to foster an
improving business climate. However, considerable uncertainty persists about the
extent and timing of the expected pickup in production and employment, owing in
part to the emergence of heightened geopolitical risks.

With the worst returns of the year in September 2002, and the S&P 500 Index at
- -10.87% for the month, the fourth quarter of 2002 brought the positive returns
that investors were hoping for, but they did not come without volatility.
October and November were significantly positive months, but December again gave
way to negative returns. Looking forward to 2003, investor confidence remains
shaken with the possibility of a military confrontation with Iraq, unanticipated
high unemployment and disappointing holiday sales. Consumer confidence
unexpectedly fell in December for the sixth time in seven months as unemployment
threatened to undermine spending and U.S. economic growth early next year.

At December 31, 2002, Merrill Lynch Small Cap Index Fund had net assets of $65.3
million, compared to $80.8 million as of December 31, 2001.

The investment objective of the Fund is to seek to replicate the return of the
Russell 2000 Index before expenses. The Fund seeks to achieve its investment by
investing all of its assets in Master Small Cap Index Series. The Series is an
underlying equity portfolio in which most of the Series' assets are placed. In
addition, the Series maintains a long position in Russell 2000 futures contracts
that are used as a mechanism to invest daily cash inflows. The Series uses
futures as a way to maintain liquidity should the need arise in the event of
Fund redemptions. At December 31, 2002, the Series had an equity portfolio
valued at $173 million, which represented approximately 95% of the Series' net
assets. In addition, the Series held a long position in the Russell 2000 March
2003 futures contracts. Through its holdings of equities and futures contracts,
our goal is to be 100% invested in the Russell 2000 Index at all times.

In Conclusion

We thank you for your investment in Merrill Lynch Small Cap Index Fund, and we
look forward to assisting you with your investment needs in the months and years
ahead.

Sincerely,


/s/ Terry K. Glenn

PERFORMANCE DATA

About Fund
Performance

Investors are able to purchase shares of the Fund, which offers two pricing
alternatives:

o     Class A Shares do not incur a maximum initial sales charge (front-end
      load) or deferred sales charge and bear no ongoing distribution or account
      maintenance fees. Class A Shares are available only to eligible investors.

o     Class D Shares do not incur a maximum initial sales charge or deferred
      sales charge and bear no ongoing distribution fee. In addition, Class D
      Shares are subject to an ongoing account maintenance fee of 0.25%.

      None of the past results shown should be considered a representation of
      future performance. 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 each of the following tables assume
      reinvestment of all dividends and capital gains distributions 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 account maintenance, distribution
      and transfer agency fees applicable to each class, which are deducted from
      the income available to be paid to shareholders. The Fund's Administrator
      and the Series' Investment Adviser voluntarily waived a portion of their
      administrative and management fees, respectively. Without such waivers,
      the Fund's performance would have been lower.

                           Merrill Lynch Small Cap Index Fund, December 31, 2002

NOTES TO FINANCIAL STATEMENTS

MERRILL LYNCH
SMALL CAP
INDEX FUND

1. Significant Accounting Policies:

Merrill Lynch Small Cap Index Fund (the "Fund") is part of Merrill Lynch Index
Funds, Inc. (the "Corporation"). The Fund is registered under the Investment
Company Act of 1940 as a non-diversified mutual fund. 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. 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 Trust, which has the same investment
objective 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 financial statements of the Series, including the Schedule of Investments,
are included elsewhere in this report and should be read in conjunction with the
Fund's financial statements. The percentage of the Series owned by the Fund at
December 31, 2002 was 35.9%. The Fund offers two classes of shares, Class A and
Class D. Shares of Class A and Class D are 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 Class D Shares bear certain expenses related to the
account maintenance of such shares and have exclusive voting rights with respect
to matters relating to its account maintenance expenditures. Income, expenses
(other than expenses attributable to a specific class) and realized and
unrealized gains and losses on investments are allocated daily to each class
based on its relative net assets. The following is a summary of significant
accounting policies followed by the Fund.

(a) Valuation of investments -- The Fund records its investment in the Series at
fair value. Valuation of securities held by the Series is discussed in Note 1a
of the Series' Notes to Financial Statements, which are included elsewhere in
this report.

(b) Investment income and expenses -- 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.

(c) 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 shareholders. 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.

(d) Prepaid registration fees -- Prepaid registration fees are charged to
expense as the related shares are issued.

(e) Dividends and distributions -- Dividends and distributions paid by the Fund
are recorded on the ex-dividend dates.

(f) Investment transactions -- Investment transactions in the Series are
accounted for on a trade date basis.

(g) Reclassification -- 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.
There were no significant reclassifications in the current year.

2. Transactions with Affiliates:

The Corporation has entered into an Administration Agreement with Merrill Lynch
Investment Managers, L.P. ("MLIM"). The general partner of MLIM is Princeton
Services, Inc. ("PSI"), a wholly-owned subsidiary of Merrill Lynch & Co., Inc.
("ML & Co."), which is the limited partner. The Fund pays a monthly fee at an
annual rate of .29% of the Fund's average daily net assets for the performance
of administrative services (other than investment advice and related portfolio
activities) necessary for the operation of the Fund. For the year ended December
31, 2002, MLIM earned fees of $219,948, of which $59,602 were waived.

The Corporation has also entered into a Distribution Agreement and Distribution
Plan with FAM Distributors, Inc. ("FAMD" or the "Distributor"), a division of
Princeton Funds Distributor, Inc. ("PFD"), which is a wholly-owned subsidiary of
Merrill Lynch Group, Inc. Pursuant to the Distribution Plan adopted by the
Corporation in accordance with Rule 12b-1 under the Investment Company Act of
1940, the Fund pays the Distributor an ongoing account maintenance fee. The fee
is accrued daily and paid monthly at the annual rate of .25% based upon the
average daily net assets of Class D Shares.

Pursuant to a sub-agreement with the Distributor, Merrill Lynch, Pierce, Fenner
& Smith Incorporated ("MLPF&S"), a subsidiary of ML & Co., also provides account
maintenance services to the Fund. The ongoing account maintenance fee
compensates the Distributor and MLPF&S for providing account maintenance
services to Class D shareholders.

Financial Data Services, Inc. ("FDS"), an indirect, wholly-owned subsidiary of
ML & Co., is the Fund's transfer agent.

Certain officers and/or directors of the Fund are officers and/or directors of
MLIM, PSI, FAMD, FDS, and/or ML & Co.

3. Investments:

Increases and decreases in the Fund's investment in the Series for the year
ended December 31, 2002 were $22,473,486 and $20,522,966, respectively.

4. Capital Share Transactions:

Net increase (decrease) in net assets derived from capital share transactions
were $2,902,479 and $(19,766,482) for the years ended December 31, 2002 and
December 31, 2001, respectively.

5. Distributions to Shareholders:

The tax character of distributions paid during the fiscal years ended December
31, 2002 and December 31, 2001 was as follows:

- -------------------------------------------------------------------------------
                                                     12/31/2002      12/31/2001

As of December 31, 2002, the components of accumulated losses on a tax basis
were as follows:

- -----------------------------------------------------------------------------
Undistributed ordinary income--net ......................        $     14,788
Undistributed long-term capital gains--net ..............                  --

Total undistributed earnings--net .......................              14,788
Capital loss carryforward ...............................          (6,541,438)*
Unrealized losses--net ..................................         (17,507,783)**
                                                                 ------------
Total accumulated losses--net ...........................        $(24,034,433)
                                                                 ============
- -----------------------------------------------------------------------------

*     On December 31, 2002, the Fund had a net capital loss carryforward of
      $6,541,438, of which $2,556,308 expires in 2009 and $3,985,130 expires in
      2010. This amount will be available to offset like amounts of any future
      taxable gains.
**    The difference between book-basis and tax-basis net unrealized losses is
      attributable primarily to the tax deferral of losses on wash sales, the
      realization for tax purposes of unrealized gains (losses) on certain
      futures contracts and the deferral of post-October capital losses for tax
      purposes.

NOTES TO FINANCIAL STATEMENTS

MASTER
SMALL CAP
INDEX SERIES

1. Significant Accounting Policies:

Master Small Cap Index Series (the "Series") is part of Quantitative Master
Series Trust (the "Trust"). The Trust is registered under the Investment Company
Act of 1940 and is organized as a Delaware business trust. The Declaration of
Trust permits the Trustees to issue nontransferable interests in the Trust,
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. 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 are valued at the last sale price as of the close of business on the
day the securities are being valued or, lacking any sales, at the closing bid
price. Securities traded in the over-the-counter market are valued at the last
quoted bid price at the close of trading on the New York Stock Exchange on each
day by brokers that make markets in the securities. Securities traded in the
NASDAQ National Market System are valued at the last sale price prior to the
time of valuation. 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. 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). Short-term
securities are valued at amortized cost, which approximates market value. Other
investments, including futures contracts and related options, are stated at
market value. Securities and assets for which market quotations are not readily
available are valued at fair market value, as determined in good faith by or
under the direction of the Trust's Board of Trustees.

(b) Derivative financial instruments -- The Series may engage in various
portfolio investment strategies 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 as a proxy for a direct
investment in securities underlying the Series' index. 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 a gain or loss to the extent
that 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. Accordingly, as a "pass through"
entity, the Series pays no income dividends or capital gains distributions.
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
accounted for on the date the securities are purchased or sold (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) Custodian bank -- The Series recorded an amount payable to the custodian
bank reflecting an overnight overdraft, which resulted from management estimates
of available cash.

(f) 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.
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 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 the expenses incurred by the Series will not exceed .08%. Effective
January 1, 2003, the limit was increased from .08% to .09%. This arrangement
expires December 31, 2003 and is renewable. FAM reimbursed the Series for
expenses of $120,169.

Merrill Lynch Trust Company, an indirect, wholly-owned Subsidiary of ML & Co.,
is the Series' Custodian.

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 Advisors, LLC ("MLIA"), an affiliate of FAM, as the securities
lending agent for a fee based on a share of the returns on investment of cash
collateral. MLIA may, on behalf of the Trust and Series, invest cash collateral
received by the Series for such loans, among other things, in a private
investment company managed by MLIA or in registered money market funds advised
by FAM or its affiliates. As of December 31, 2002, cash collateral of $2,784,435
was invested in the Money Market Series of the Merrill Lynch Liquidity Series,
LLC and $2,469,215 was invested in the Merrill Lynch Premier Institutional Fund.
As of December 31, 2002, the Series lent securities with a value of $475,396 to
MLPF&S or its affiliates. For the year ended December 31, 2002, MLIA received
$15,370 in securities lending agent fees from the Series.

In addition, MLPF&S received $24 in commissions on the execution of Portfolio
security transactions for the Series for the year ended December 31, 2002.

withdrawals 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. The Fund did not borrow under the
credit agreement during the year ended December 31, 2002.

INDEPENDENT AUDITORS' REPORT

The Board of Trustees and Investors,
Master Small Cap Index Series
(One of the series constituting
Quantitative Master Series Trust):

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Master Small Cap Index Series (one of the series
constituting Quantitative Master Series Trust) as of December 31, 2002, the
related statements of operations for the year then ended, and changes in net
assets for each of the two years in the two-year period then ended, and the
financial highlights for each of the years presented. These financial statements
and the financial highlights are the responsibility of the Trust's management.
Our responsibility is to express an opinion on these financial statements and
the financial highlights based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements and the financial highlights are free of material misstatement. An
audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned at December 31, 2002 by correspondence with the custodian and
brokers; where replies were not received from brokers, we performed other
auditing procedures. An audit also includes 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, such financial statements and financial highlights present
fairly, in all material respects, the financial position of Master Small Cap
Index Series of the Quantitative Master Series Trust as of December 31, 2002,
the results of its operations, the changes in its net assets, and the financial
highlights for the respective stated periods in conformity with accounting
principles generally accepted in the United States of America.
