A Letter From the President and Chief Investment Officer

Dear Shareholder

The U.S. equity market ended 2004 in positive territory, although not without
some suspense along the way. Fixed income markets also performed well, with high
yield bond investors enjoying some of the greatest returns.

Over the past year, the equity market generally found support from a healthy
economic environment, above-average corporate earnings, increased capital
spending and still-low interest rates. Stalling the momentum somewhat throughout
the year was a contentious election, negligible inflation amid a rising federal
funds interest rate, record-high oil prices and the seemingly ever-present
worries over terrorism and the war in Iraq.

Still, the Standard & Poor's 500 Index posted a 12-month return of +10.88% and a
six-month return of +7.19% as of December 31, 2004. The fourth quarter of the
year proved to be the most telling, as the S&P 500 Index was up only 1.51%
year-to-date as of September 30, 2004. As the price of oil relaxed and election
uncertainties subsided, the market headed more convincingly upward in the last
quarter of the year.

Given the relatively positive environment for equities, the favorable
performance of the bond market came as somewhat of a surprise. The Lehman
Brothers Aggregate Bond Index posted a 12-month return of +4.34% and a six-month
return of +4.18% as of December 31, 2004. The tax-exempt market performed just
as well, with a 12-month return of +4.48% and a six-month return of +5.19%, as
measured by the Lehman Brothers Municipal Bond Index. Those comfortable with a
higher degree of risk benefited this past year, as the Credit Suisse First
Boston High Yield Index posted a 12-month return of +11.95% and a six-month
return of +9.26%. Interestingly, as the Federal Reserve Board began raising its
target short-term interest rate, long-term bond yields were little changed. In
fact, the yield on the 10-year Treasury was 4.24% at year-end compared to 4.27%
at December 31, 2003. The yield on the two-year Treasury climbed to 3.08% at
year-end 2004 from 1.84% a year earlier.

As always, our investment professionals are closely monitoring the markets, the
economy and the overall environment in an effort to make well-informed decisions
for the portfolios they manage. For the individual investor, the key to
investment success -- particularly during uncertain times -- is to maintain a
long-term perspective and adhere to the disciplines of asset allocation,
diversification and rebalancing. We encourage you to work with your financial
advisor to ensure these time-tested techniques are incorporated into your
investment plan.

We thank you for trusting Merrill Lynch Investment Managers with your investment
assets, and we look forward to serving you in the new year and beyond.

                                          Sincerely,


                                          /s/ Robert C. Doll, Jr.

                                          Robert C. Doll, Jr.
                                          President and Chief Investment Officer

A Discussion With Your Fund's Portfolio Managers

      The Fund was able to meet its objective of closely tracking the
performance of the Russell 2000 Index for the year.

How did the Fund perform during the fiscal year?

For the 12-month period ended December 31, 2004, Merrill Lynch Small Cap Index
Fund's Class A and Class I Shares had total returns of +17.29% and +17.55%,
respectively. For the same period, the Fund's benchmark, the Russell 2000 Index,
returned +18.33%. (Complete performance information can be found on pages 6 and
7 of this report to shareholders.)

The Fund met its objective of closely tracking the return of the Russell 2000, a
market-weighted index composed of approximately 2,000 common stocks issued by
small-capitalization U.S. companies in a range of businesses. As the value of
the Russell 2000 Index fluctuated during the year, the Fund's performance
generally tracked that of the Index. Throughout the year, as changes were made
to the composition of the Russell 2000 Index, we purchased and sold securities
to maintain our objective of replicating the risks and return of the benchmark.

As an index fund, the portfolio mirrors the composition of the Russell 2000
Index, a common measure of U.S. market performance for small cap stocks. What
developments affected the market for small cap stocks during the period?

The year 2004 proved to be a positive one for U.S. equity markets, and
particularly for small cap stocks, as indicated by the +18.33% return of the
Russell 2000 Index. By comparison, the Russell 1000 Index, which measures the
performance of large-capitalization stocks, returned +11.40% for the 12 months
ended December 31, 2004.

The beginning of 2004 brought a significant rise in equities, driven by
better-than-expected corporate earnings. The second quarter showed flat to
positive returns for the domestic equity markets, influenced mainly by
indecisive investors. This behavior stemmed from continued political tension in
the United States, violence in Iraq and record-high oil prices. A shift in
investor favor from lower-quality, lower-price and higher-beta (riskier)
securities to higher-quality, higher-cap and lower-beta stocks took place at the
end of the first quarter and grew stronger in the second quarter. For the first
half of 2004, the Russell 1000 Index returned +3.33% and the Russell 2000 Index
returned +6.76%. Large cap stocks showed some strength mid-year, but small caps
rebounded in the fourth quarter. Overall, small caps outperformed large caps for
the sixth consecutive year in 2004.

As the third quarter progressed, the course of economic news slowly began to
point toward a strengthening economy. However, the stock market still faced a
number of challenges, including the geopolitical situation, higher oil prices,
U.S. election uncertainty and a shifting Federal Reserve Board (the Fed) policy.
The fourth quarter, however, proved to be the breakout that investors were
looking for in the U.S. equity markets, as negative October headlines segued
into positive November and December news. As a result of lower 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, more than doubling it from 1% to 2.25% by
year-end.

On December 31, 2004, the Standard & Poor's 500 Index closed 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 delivered comparable gains,
with the Financial Times Stock Exchange 100 Index closing at 4,814.30,
representing a return of +7.54% in sterling. Meanwhile, 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.

As the returns indicate, small cap stocks (as measured by the Russell 2000
Index) outperformed the broader market during the year. Within the small cap
universe, the value style of investing outperformed the growth style for the
year, with the Russell 2000 Value Index returning +22.25% versus the +14.31%
return of the Russell 2000 Growth Index. Turning


4       MERRILL LYNCH SMALL CAP INDEX FUND              DECEMBER 31, 2004


to sector performance, 11 of the 12 Russell 2000 Index sectors posted positive
returns for the year. The top-performing sector was "other energy," which
consists of energy-related businesses, excluding integrated oils. The sector
gained an impressive +50.51% for the year and was followed by "other" (a
category that includes many conglomerates) and integrated oils, which returned
+44.78% and +38.05%, respectively. Technology was by far the worst-performing
sector in the Index, returning -1.85%. It was followed by consumer staples, up
13.50%, and health care, up 15.90%.

How would you characterize market conditions at the close of the period?

As 2004 came to an end, the economy and earnings growth were beginning to slow,
the Fed appeared poised to continuing 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 recent rate hike, but clearly have been benefiting from 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 well. Having said that, we expect the
portfolio to continue to meet its objective of tracking the performance of the
Russell 2000 Index in 2005.

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 an initial sales charge (front-end load) or
      deferred sales charge and bear no ongoing distribution fee. In addition,
      Class A Shares are subject to an ongoing account maintenance fee of .25%
      per year.

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

None of the past results shown should be considered a representation of future
performance. Current performance may be lower or higher than the performance
data quoted. Refer to www.mlim.ml.com to obtain performance data current to the
most recent month-end. Performance results do not reflect the deduction of taxes
that a shareholder would pay on fund distributions or the redemption of fund
shares. The Fund is subject to a 2% redemption fee for sales or exchanges of
shares within 30 days of purchase. Performance data does not reflect this
potential fee. Figures shown in each of the following tables assume reinvestment
of all dividends and capital gain distributions, if any, at net asset value on
the ex-dividend date. Investment return and principal value of shares will
fluctuate so that shares, when redeemed, may be worth more or less than their
original cost. Dividends paid to each class of shares will vary because of the
different levels of 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.

Disclosure of Expenses

Shareholders of this Fund may incur the following charges: (a) expenses related
to transactions, including sales charges, redemption fees and exchange fees; and
(b) operating expenses including advisory fees, distribution fees including
12(b)-1 fees, and other Fund expenses. The following example (which is based on
a hypothetical investment of $1,000 invested on July 1, 2004 and held through
December 31, 2004) is intended to assist shareholders both in calculating
expenses based on an investment in the Fund and in comparing these expenses with
similar costs of investing in other mutual funds.

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

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

The expenses shown in the table are intended to highlight shareholders ongoing
costs only and do not reflect any transactional expenses, such as sales charges,
redemption fees or exchange fees. Therefore, the second table is useful in
comparing ongoing expenses only, and will not help shareholders determine the
relative total expenses of owning different funds. If these transactional
expenses were included, shareholder expenses would have been higher.



                                                                                                     Expenses Paid

*     For each class of the Fund, expenses are equal to the annualized expense
      ratio for the class (.82% for Class A and .57% for Class I), multiplied by
      the average account value over the period, multiplied by 184/366 (to
      reflect the one-half year period shown). Because the Fund is a feeder
      fund, the expense table example reflects the expenses of both the feeder
      fund and the master series in which it invests.
**    Hypothetical 5% annual return before expenses is calculated by pro-rating
      the number of days in the most recent fiscal half year divided by 366.

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 amended, as a non-diversified mutual fund. 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 and strategy 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 Fund's financial statements 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 percentage of the Series owned by the Fund at December 31, 2004
was 34.1%. The Fund offers two classes of shares. Shares of Class A and Class I
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 A 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 and foreign
currency transactions 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 -- U.S. generally accepted accounting principles require
that certain components of net assets be adjusted to reflect permanent
differences between financial and tax reporting. Accordingly, during the current
year, $279 has been reclassified between paid-in capital in excess of par and
undistributed net investment income as a result of a permanent difference
attributable to nondeductible expenses. This reclassification has no effect on
net assets or net asset values per share.

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. MLIM has entered into a
voluntary arrangement with the Fund under which all expenses incurred by the
Fund (excluding account maintenance fees) will not exceed .60%. This arrangement
has a one year term and is renewable. For the year ended December 31, 2004, MLIM
earned fees of $319,410, of which $1,954 were waived.

The Corporation has also entered into a Distribution Agreement and Distribution
Plan with FAM Distributors, Inc. ("FAMD" or the "Distributor"), 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 A Shares.

maintenance services to the Fund. The ongoing account maintenance fee
compensates the Distributor and MLPF&S for providing account maintenance
services to Class A shareholders.

*     On December 31, 2004, the Fund had a net capital loss carryforward of
      $1,951,093, all of which 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 gains is
      attributable primarily to the tax deferral of losses on wash sales and the
      realization for tax purposes of unrealized gains on certain futures
      contracts.

Report of Independent Registered Public Accounting Firm
                                              Merrill Lynch Small Cap Index Fund

To the Shareholders and Board of Directors of
Merrill Lynch Index Funds, Inc.:

We have audited the accompanying statement of assets and liabilities of Merrill
Lynch Small Cap Index Fund, one of the series constituting Merrill Lynch Index
Funds, Inc. (the "Fund"), 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 five years in the period then ended. These financial statements and
financial highlights are the responsibility of the Fund's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. 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 Fund's
internal control over financial reporting. Accordingly, we express no such
opinion. An audit also includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Merrill Lynch Small Cap Index Fund of Merrill Lynch Index Funds, Inc. 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 five years in the period then
ended, in conformity with U.S. generally accepted accounting principles.

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, as amended, and is organized as a Delaware statutory 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 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 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 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 Trustees of the Trust, including valuations furnished by the
pricing services retained by the Series, which may use a matrix system for
valuations. The procedures of a pricing service and its valuations are reviewed
by the officers of the Series 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 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 strategies both to increase the return of the Series and to
hedge, or protect, its exposure to interest rate movements and movements in the
securities markets. 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. Futures contracts
      are contracts for delayed delivery of securities at a specific future date
      and at a specified 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 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. 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) 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 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 .08%. This arrangement
has a one-year term and is renewable. FAM reimbursed the Series for the amount
of $2,910.

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

Merrill Lynch Trust Company ("MLTC"), 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") or its affiliates. As of December 31,
2004, the Series lent securities with a value of $246,974 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
Series advised by FAM or its affiliates. For the year ended December 31, 2004,
MLIM, LLC received $50,177 in securities lending agent fees from the Series.

For the year ended December 31, 2004, the Series reimbursed FAM $7,957 for
certain accounting services.

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

3. Investments:

Purchases and sales of investments, excluding short-term securities, for the
year ended December 31, 2004 were $138,270,159 and $125,776,247, respectively.

4. Short-Term Borrowings:

The Trust, on behalf of 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
                                                   Master Small Cap Index Series

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

We have audited the accompanying statement of assets and liabilities, including
the summary schedule of investments, of Master Small Cap Index Series, one of
the portfolios constituting Quantitative Master Series 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 five years in
the period 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
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation. Our procedures
included confirmation of securities owned as of December 31, 2004, by
correspondence with the custodian and brokers; where replies were not received
from brokers, we performed other auditing procedures. We believe that our audits
provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of Master
Small Cap Index Series of 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 five years in the period then ended, in
conformity with U.S. generally accepted accounting principles.

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.

         (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.

         (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.

                        OF THE SARBANES-OXLEY ACT OF 2002

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

I, Robert C. Doll, Jr., Chief Executive Officer of Small Cap Index Fund of
Merrill Lynch Index Funds, Inc. and Master Small Cap Index Series of
Quantitative Master Series Trust, certify that:

      1.    I have reviewed this report on Form N-CSR of Small Cap Index Fund of
            Merrill Lynch Index Funds, Inc. and Master Small Cap Index Series of
            Quantitative Master Series Trust (together, the "Fund");

      2.    Based on my knowledge, this report does not contain any untrue
            statement of a material fact or omit to state a material fact
            necessary to make the statements made, in light of the circumstances
            under which such statements were made, not misleading with respect
            to the period covered by this report;

      3.    Based on my knowledge, the financial statements, and other financial
            information included in this report, fairly present in all material
            respects the financial condition, results of operations, changes in
            net assets, and cash flows (if the financial statements are required
            to include a statement of cash flows) of the Fund as of, and for,
            the periods presented in this report;

      4.    The Fund's other certifying officer(s) and I are responsible for
            establishing and maintaining disclosure controls and procedures (as
            defined in Rule 30a-3(c) under the Investment Company Act of 1940)
            and internal control over financial reporting (as defined in Rule
            30a-3(d) under the Investment Company Act of 1940) for the Fund and
            have:

            a)    designed such disclosure controls and procedures, or caused
                  such disclosure controls and procedures to be designed under
                  our supervision, to ensure that material information relating
                  to the Fund, including its consolidated subsidiaries, is made
                  known to us by others within those entities, particularly
                  during the period in which this report is being prepared;

            b)    evaluated the effectiveness of the Fund's disclosure controls
                  and procedures and presented in this report our conclusions
                  about the effectiveness of the disclosure controls and
                  procedures, as of a date within 90 days prior to the filing
                  date of this report based on such evaluation; and



            c)    disclosed in this report any change in the Fund's internal
                  control over financial reporting that occurred during the
                  Fund's most recent fiscal half-year (the Fund's second fiscal
                  half-year in the case of an annual report) that has materially
                  affected, or is reasonably likely to materially affect, the
                  Fund's internal control over financial reporting; and

      5.    The Fund's other certifying officer(s) and I have disclosed to the
            Fund's auditors and the audit committee of the Fund's board of
            directors (or persons performing the equivalent functions):

            a)    all significant deficiencies and material weaknesses in the
                  design or operation of internal control over financial
                  reporting which are reasonably likely to adversely affect the
                  Fund's ability to record, process, summarize, and report
                  financial information; and

            b)    any fraud, whether or not material, that involves management
                  or other employees who have a significant role in the Fund's
                  internal control over financial reporting.
