A Letter From the President

Dear Shareholder

On balance, 2005 was a year of "muddling through" for the U.S. financial
markets, as oil prices reached new record highs, the Federal Reserve Board (the
Fed) increased the target federal funds rate from 2.25% to 4.25%, the housing
market and the consumer finally showed some signs of slowing, and Hurricanes
Katrina and Rita ravaged the Gulf Coast, causing yet untold economic damage.

Although they struggled, stocks managed to post their third straight year of
positive performance. The year was equally uncertain for fixed income markets,
which were bemused by a flattening yield curve and a number of significant
credit events that brought a slowdown in high yield market returns. Notably, the
one-year results for the major asset classes -- stocks, bonds and cash -- were
the closest they have been in more than 100 years. For the 12- and six-month
periods ended December 31, 2005, most of the major market indexes managed to
land in positive territory:

=================================================================================================

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


In hindsight, these numbers are reasonably good given the headwinds facing the
markets in 2005. U.S. equities found support in strong corporate earnings, low
core inflation and healthy company balance sheets. Strength in the global
economy and non-U.S. equity markets helped, as did robust dividend-distribution,
share-buyback and merger-and-acquisition activity. International stocks had an
excellent year, with many markets benefiting from strong economic statistics,
trade surpluses and solid finances. In the U.S. bond market, long-term yields
remained low and, at year-end, the Treasury curve appeared ready to invert.

As 2006 begins, the largest question marks center on the Fed's future moves, the
U.S. consumer's ability (or inability) to continue spending, the direction of
the U.S. dollar following a year of appreciation and the potential for continued
strong economic and corporate earnings growth. As you turn the calendar and
consider how these factors might impact your investments, remember that the new
year is a good time to meet with your financial advisor to review your financial
goals, and to make portfolio changes where necessary. For investing insights and
timely "food for thought" for investors, we also invite you to visit Shareholder
magazine at www.mlim.ml.com/shareholdermagazine.

As always, 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 Director/Trustee

A Discussion With Your Fund's Portfolio Managers

      For the fiscal year, the Fund provided positive double-digit returns
similar to that of the MSCI EAFE Index.

How did the Fund perform during the fiscal year in light of the existing market
conditions?

For the 12-month period ended December 31, 2005, Merrill Lynch International
Index Fund's Class A and Class I Shares had total returns of +12.81% and
+13.19%, respectively. For the same period, the benchmark Morgan Stanley Capital
International Europe, Australasia, Far East (MSCI EAFE) Index returned +13.54%.

The MSCI EAFE Index is a free-float adjusted market-weighted index designed to
measure equity performance of developed markets, excluding the United States and
Canada. As the value of the MSCI EAFE Index fluctuated during the past 12
months, the Fund's performance generally tracked that of the Index.

International equity markets generated positive performance in 2005 as developed
markets around the world strengthened on optimistic economic reports. In fact,
throughout the year, international equity markets outperformed U.S. equity
markets.

European equity markets performed well in 2005 as 14 of 16 European MSCI country
indexes posted positive gains. A key reason behind the upbeat outlook for world
economic growth was that inflation retreated in most regions, especially in
Europe and Japan. Despite the July terrorist attacks in London, worries about
the economic impact of hurricanes in the United States, and higher energy costs,
European equity markets performed strongly in the second half of 2005. In
December, European manufacturing growth advanced at its fastest pace in 16
months, while German unemployment declined by its greatest amount in more than
15 years. Economic growth accelerated as companies stepped up their hiring and
investment activity, which in turn increased optimism that consumers would spend
more and bolster Europe's export-driven economy. The strongest-performing
European markets of 2005 were Austria, Norway and Finland, which gained 24.64%,
24.26% and 16.69%, respectively. Ireland and Portugal returned -2.29% and
- -1.87%, respectively, and were the only two markets in Europe to post negative
returns last year. The European Central Bank raised interest rates 25 basis
points (.25%) for the first time since 2000, leaving the region's benchmark rate
at 2.25%.

In Asia, all five MSCI country indexes gained ground in 2005. Japan turned in
the strongest growth in the region, returning +25.52%. Business confidence in
that country climbed to its highest level in a year, and Japanese companies plan
to invest in their businesses at the fastest pace since 1990, according to the
Bank of Japan's Tankan business confidence survey. Other strong performers in
the region included Australia (+16.02%), Singapore (+14.37%) and Hong Kong
(+8.40%).

In 2005, the U.S. dollar gained 12.7% against the euro, 10.6% against the
British pound and 15% against the Japanese yen. Exchange rates were largely
driven by interest rate decisions and expectations in the United States.
Interest rates are expected to continue driving exchange rates as the Federal
Reserve Board winds down its interest rate-hiking campaign.

What changes were made to the portfolio during the period?

Throughout the year, as changes were made to the composition of the MSCI EAFE
Index, the portfolio purchased and sold securities to maintain its objective of
replicating the risks and return of the benchmark.

How would you characterize the Fund's position at the close of the period?

We believe the portfolio remains positioned to match the risk characteristics of
its benchmark, regardless of the direction of international markets.

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 0.25%
      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 may charge a 2% redemption fee for sales or exchanges of shares
within 30 days of purchase or exchange. 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 and transfer agency fees applicable to
each class, which are deducted from the income available to be paid to
shareholders. The Fund's Investment Adviser reimbursed a portion of the Fund's
fee. Without such reimbursement, 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
12b-1 fees, and other Fund expenses. The following example (which is based on a
hypothetical investment of $1,000 invested on July 1, 2005 and held through
December 31, 2005) 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.

*    For each class of the Fund, expenses are equal to the annualized expense
     ratio for the class (.80% for Class A and .55% for Class I), multiplied by
     the average account value over the period, multiplied by 183/365 (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 365.

12      MERRILL LYNCH INTERNATIONAL INDEX FUND          DECEMBER 31, 2005


Notes to Financial Statements             Merrill Lynch International Index Fund

1. Significant Accounting Policies:

Merrill Lynch International 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 International Index Series (the "Series") of the Quantitative
Master Series Trust, which has the same investment objective and strategies 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, 2005
was 47.9%. 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 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 1(a)
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 its shareholders.
Therefore, no federal income tax provision is required.

(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, $1,045,570 has been reclassified between undistributed net investment
income and accumulated realized net capital losses on investments as a result of
permanent differences attributable to gains from the sale of stock of passive
foreign investment companies and foreign currency transactions. 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 Services 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 .34% 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 the expenses incurred by
each class of shares of the Fund (excluding account maintenance fees) will not
exceed .65%. This arrangement has a one-year term and is renewable. MLIM earned
fees of $705,801, of which $12,656 were waived.

The Fund may pay a monthly investment advisory fee at an annual rate of .01%
based upon the average daily value of the Fund's net assets. However, the
Investment Adviser has entered into a contractual agreement with the Fund
pursuant to which the investment advisory fee will not be charged to the Fund so
long as the Fund remains invested in the Series. As a result, the investment
advisory fee has not been accrued and will not be payable by the Fund for the
period covered by this report.

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 INTERNATIONAL INDEX FUND          DECEMBER 31, 2005     13


Notes to Financial Statements (concluded)
                                          Merrill Lynch International Index Fund

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 ongoing account maintenance fees. The fees
are accrued daily and paid monthly at the annual rate of .25% based upon the
average daily net assets of Class A Shares.

Pursuant to a sub-agreement with the Distributor, Merrill Lynch, Pierce, Fenner
& Smith Incorporated ("MLPF&S"), an affiliate of MLIM, 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 A 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.

were as follows:

- -----------------------------------------------------------------------------
Undistributed ordinary income--net ......................        $    384,905
Undistributed long-term capital gains--net ..............                  --

Total undistributed earnings--net .......................             384,905
Capital loss carryforward ...............................            (575,690)*
Unrealized gains--net ...................................          46,691,614**
                                                                 ------------

*     On December 31, 2005, the Fund had a net capital loss carryforward of
      $575,690, 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, the
      realization for tax purposes of unrealized gains/losses on certain foreign
      currency contracts, the realization for tax purposes of unrealized gains
      on investments in passive foreign investment companies and other book/tax
      temporary differences.

Report of Independent Registered Public Accounting Firm
                                          Merrill Lynch International 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 International Index Fund, one of the series constituting Merrill Lynch
Index Funds, Inc. (the "Fund"), as of December 31, 2005, 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 the financial highlights are free of material misstatement. The
Fund is not required to have, nor were we engaged to perform, an audit of its
internal control over financial reporting. Our audits included consideration of
internal control over financial reporting as a basis for designing audit
procedures that are appropriate in the circumstances, but not for the purpose of
expressing an opinion on the effectiveness of the 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 International Index Fund of Merrill Lynch Index Funds, Inc. as of
December 31, 2005, 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 International Index Series

1. Significant Accounting Policies:

Master International Index Series (the "Series"), a non-diversified investment
company, 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 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 asked
price for short positions. In cases where equity securities are traded on more
than one exchange, the securities are valued on the exchange designated as the
primary market by or under the authority of the Board of 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 asked price. Portfolio securities that are traded both in the
OTC market and on a stock exchange are valued according to the broadest and most
representative market.

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 asked
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 and forward foreign exchange contracts are
valued daily based upon quoted fair valuations received daily by the Fund from a
pricing service or counterparty. Financial futures contracts and options
thereon, which are traded on exchanges, are valued at their last sale price as
of the close of such exchanges. 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 Trust's Board
of Trustees. 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 Portfolio
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 Trust's Board of Trustees or by the Investment
Adviser using a pricing service and/or procedures approved by 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. 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,


26      MERRILL LYNCH INTERNATIONAL INDEX FUND          DECEMBER 31, 2005


Notes to Financial Statements (continued)      Master International Index Series

      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.

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 also 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) Foreign currency transactions -- Transactions denominated in foreign
currencies are recorded at the exchange rate prevailing when recognized. Assets
and liabilities denominated in foreign currencies are valued at the exchange
rate at the end of the period. Foreign currency transactions are the result of
settling (realized) or valuing (unrealized) assets or liabilities expressed in
foreign currencies into U.S. dollars. Realized and unrealized gains or losses
from investments include the effects of foreign exchange rates on investments.
The Series invests in foreign securities, which may involve a number of risk
factors and special considerations, not present with investments in securities
of U.S. corporations.

(d) 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.

(e) 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.
Dividends from foreign securities where the ex-dividend date may have passed are
subsequently recorded when the Series has determined the ex-dividend date.
Interest income is recognized on the accrual basis.

(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. 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


        MERRILL LYNCH INTERNATIONAL INDEX FUND          DECEMBER 31, 2005     27


Notes to Financial Statements (concluded)      Master International Index Series

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
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 .12%. This arrangement
has a one-year term and is renewable. For the year ended December 31, 2005, FAM
reimbursed the Series in the amount of $13,001.

For the year ended December 31, 2005, the Series reimbursed FAM $9,236 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
year ended December 31, 2005 were $170,663,540 and $45,344,153, respectively.

4. Commitments:

At December 31, 2005, the Series had entered into foreign exchange contracts, in
addition to the contracts listed in the Schedule of Investments, under which it
had agreed to sell a foreign currency with an approximate value of $64,000.

5. 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, 2005. On November 23,
2005, the credit agreement was renewed for one year under substantially the same
terms.

Report of Independent Registered Public Accounting Firm
                                               Master International 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 International Index Series, one
of the portfolios constituting the Quantitative Master Series Trust (the
"Trust") as of December 31, 2005, 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. The Trust
is not required to have, nor were we engaged to perform, an audit of its
internal control over financial reporting. Our audits included consideration of
internal control over financial reporting as a basis for designing audit
procedures that are appropriate in the circumstances, but not for the purpose of
expressing an opinion on the effectiveness of the 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, 2005, 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
International Index Series of the Quantitative Master Series Trust as of
December 31, 2005, 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.

         (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
