After raising the target short-term interest rate 17 times between June 2004 and
June 2006, the Federal Reserve Board (the Fed) finally opted to pause on August
8, 2006. This left the federal funds rate at 5.25%, where it remained through
year-end. In interrupting its two-year interest rate-hiking campaign, the Fed
acknowledged that economic growth is slowing, led by a downturn in the housing
market, but has maintained a cautionary view on inflation.

Overall, it was a good 12 months for U.S. equities, despite a significant
correction in the middle of the year that was largely triggered by rising
interest rates, inflation fears, elevated oil prices and geopolitical
uncertainties. Nevertheless, strong corporate earnings, abundant liquidity and
record merger-and-acquisition activity provided a solid backdrop for stocks.
Many international equity markets (with the notable exception of Japan)
performed even better, outpacing U.S. stocks for the fifth consecutive year.
Strength was especially notable in European equities and select emerging
markets.

Bonds experienced a more modest annual return than stocks. Interest rates and
bond yields moved higher for much of the year as bond prices, which move
opposite of yields, declined. Prices began to improve in the summer as the
economy showed signs of weakening and the Fed paused. Notably, the Treasury
curve remained inverted for much of 2006. The 10-year Treasury yield ended
December at 4.71%, well below the federal funds rate.

As we begin a new year, investors are left with a few key questions: Will the
U.S. economy achieve a soft landing, will the Fed reverse its prior policy and
cut interest rates, and how might these outcomes impact the investment climate.
As you navigate the uncertainties inherent in the financial markets, we
encourage you to start the year by reviewing your investment goals with your
financial professional and making portfolio changes, as needed. For more
reflection on 2006 and our thoughts on the year ahead, please ask your financial
professional for a copy of "What's Ahead in 2007: An Investment Perspective," or
view it online at www.blackrock.com/funds. We thank you for trusting BlackRock
with your investment assets, and we look forward to continuing to serve you in
the new year and beyond.

                                                  Sincerely,


                                                  /s/ Robert C. Doll, Jr.

A Discussion With Your Fund's Portfolio Managers

      Fund performance essentially paced that of the MSCI EAFE Index for the
fiscal year, as international markets enjoyed another year of solid double-digit
returns.

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

For the 12-month period ended December 31, 2006, BlackRock International Index
Fund's (formerly Merrill Lynch International Index Fund) Institutional and
Investor A Shares had total returns of +26.09% and +25.85%, respectively. For
the same period, the benchmark Morgan Stanley Capital International Europe,
Australasia, Far East (MSCI EAFE) Index returned +26.34%.

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

Non-U.S. markets outperformed their U.S. counterparts for the fifth consecutive
year, as the Index return illustrates. U.S. stocks, as measured by the Standard
& Poor's 500 Index, returned +15.79% in 2006, while the MSCI Europe Index and
the MSCI Pacific Index gained 33.72% and 12.20%, respectively, in U.S.-dollar
terms. Strength was especially noticeable in Europe (in both developed and
emerging markets), which benefited from robust economic growth, high levels of
merger-and-acquisition (M&A) activity and the significant appreciation of the
euro versus the dollar. Leadership also came from many Asian markets, with the
notable exception of Japan, which was hurt by struggling economic growth. Among
the standouts were India's Bombay Sensex Index, which rose 47%, Hong Kong's Hang
Seng Index, which advanced 34%, and most remarkably, the MSCI China A Index,
which posted a +128% return.

There were two major themes in global equity markets at the end of 2006. First,
the bull market persisted, although volatility permeated the annual period.
Second, the more cyclical markets, on average, continued to outperform, with
particularly strong results from emerging markets. Japan remained an
underperformer versus other global markets, notwithstanding a significant bounce
toward the end of the year.

The year began with solid performance across most non-U.S. market indexes,
thanks to solid operational results and a generally robust corporate sector that
benefited from a record pace of global M&A activity. Evidence of an economic
slowdown began to mount, however, with investor sentiment taking a negative turn
in the second quarter. Profit-taking, global concerns over moderating economic
growth, rising energy prices, overall higher interest rates and a resurgence of
inflation fears weighed on equity markets worldwide. By May, these concerns
culminated in a significant broad-based market correction, where the average
U.S. stock fell by about 12% and non-U.S. equities suffered even greater losses.

Positive momentum did return to the market in the second half of 2006, though
global economic growth moderated. Still, the prevailing growth rate in the
global economy remains fairly robust, hovering right around the long-term trend
rate. This reflects both the boom conditions that characterized the start of the
year and the fact that the slowdown has been moderate rather than abrupt. The
United States was the weakest of the major regions in terms of economic growth
in the second half, with third quarter 2006 gross domestic product (GDP) rising
at an annual rate of 2.2%, down from the 2.6% growth rate seen in the second
quarter. Economic conditions in Asia were mixed, while continental Europe and
the United Kingdom exhibited only limited signs of a slowdown -- even after a
period long enough for the impact of a weaker U.S. economy to filter through.

Strong growth in corporate earnings and significant upward revisions to earnings
expectations have buttressed equity markets since 2003. Although the rate of
upgrading has slowed from the exceptionally strong levels seen in previous
years, recent news from the major corporate sectors generally has been upbeat.
Earnings came in ahead of expectations in the last earnings rounds in Europe,
Japan and the United States, supporting the second-half rally in equities.
Historic global profit growth is still around 20%.

Notably, in the latter half of the year, crude oil prices collapsed after
reaching an all-time high near $78 per barrel in July. As a result, headline
inflation rates in many countries dropped sharply. Central banks also were less
active. In the United States, the Federal Reserve Board has been on hold since
mid year. Additionally, there have been fewer tightening measures in Asia, with
the recent exception of India, which saw a rise in reserve requirements. The
European Central Bank, on the other hand, continued its rate-normalization
process and rates in the United Kingdom are likely to rise modestly.


4       BLACKROCK INTERNATIONAL INDEX FUND      DECEMBER 31, 2006


Turning to regional performance, all 16 European MSCI country indexes delivered
exceptional double-digit gains for the 12-month period, in U.S.-dollar terms.
Key drivers of performance included record levels of M&A activity, improving
European consumer sentiment, which amplified healthy measures of business
confidence, as well as a significant improvement in corporate profitability that
resulted from the ongoing consolidation and streamlining efforts of European
businesses. The strongest-performing markets were Spain (+49.36%), Portugal
(+47.37%) and Ireland (+46.81%).

Markets in the Australasia/Far East region continued to perform well, although
at a slower growth rate than at the beginning of 2006. For the year, Singapore
gained +46.71%, Australia rose +30.86% and Hong Kong advanced +30.35%, in
U.S.-dollar terms. New Zealand grew more slowly in comparison, but still posted
a solid return of +16.56%.

The Japanese equity market failed to keep pace with the world's biggest
developed markets in 2006, despite improving economic fundamentals and robust
corporate earnings. After a strong 2005, Japan's Nikkei 225 returned only 6% in
2006, primarily due to concerns that weak consumption spending could halt the
nation's economic recovery. GDP in Japan has grown at an annualized rate of 1%
since the spring, with the only areas of strength being exports and business
investment (which is itself highly correlated with exports). Also, noticeably
absent from the Japanese market is M&A activity, which has driven substantial
outperformance in many other developed markets, most particularly in Europe.

All global sectors in the MSCI EAFE Index posted positive double-digit returns
during the annual period, in U.S.-dollar terms. The best-performing sector by
far was utilities (+49.04%), driven by the preponderance of takeover activity in
this area. Other leaders included materials (+32.00%), telecommunication
services (+29.54%) and consumer staples (+29.42%).

In terms of currency performance, despite weakening dramatically toward
year-end, the U.S. dollar outperformed most major currencies in 2006,
registering gains of 10.6% and 12.3% against the euro and the pound,
respectively, but declining 1.0% versus the yen.

What changes were made to the portfolio during the period?

Throughout the period, 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

Effective October 2, 2006, the Fund's Class A and Class I Shares were
redesignated Investor A and Institutional Shares, respectively.

The Fund has multiple classes of shares:

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

o     Investor A Shares do not incur an initial sales charge (front-end load) or
      deferred sales charge and bear no ongoing distribution fee. In addition,
      Investor A Shares are subject to an ongoing service fee of 0.25% per year.

Performance information reflects past performance and does not guarantee future
results. Current performance may be lower or higher than the performance data
quoted. Refer to www.blackrock.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 service 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, 2006 and held through
December 31, 2006) 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 (.44% for Institutional and .69% for Investor A),
      multiplied by the average account value over the period, multiplied by
      182/365 (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      BLACKROCK INTERNATIONAL INDEX FUND      DECEMBER 31, 2006


Notes to Financial Statements                 BlackRock International Index Fund

1. Significant Accounting Policies:

On September 29, 2006, Merrill Lynch International Index Fund, a series of
Merrill Lynch Index Funds, Inc., was renamed BlackRock International Index Fund
(the "Fund"), a series of BlackRock Index Funds, Inc. (the "Corporation"),
respectively. The Fund is registered under the Investment Company Act of 1940,
as amended, as a non-diversified open-end investment company. The Fund seeks to
achieve its investment objective by investing all of its assets in Master
International Index Series (the "Series") of Quantitative Master Series Trust
(the "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, 2006
was 39.9%. The Fund offers two classes of shares. Effective October 2, 2006,
Class I and Class A Shares were redesignated Institutional and Investor A
Shares, respectively. Institutional and Investor A Shares 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 Investor 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) Recent accounting pronouncements -- In July 2006, the Financial Accounting
Standards Board ("FASB") issued Interpretation No. 48 ("FIN 48"), "Accounting
for Uncertainty in Income Taxes -- an interpretation of FASB Statement No. 109."
FIN 48 prescribes the minimum recognition threshold a tax position must meet in
connection with accounting for uncertainties in income tax positions taken or
expected to be taken by an entity including mutual funds before being measured
and recognized in the financial statements. Adoption of FIN 48 is required for
the last net asset value calculation in the first required financial statement
reporting period for fiscal years beginning after December 15, 2006. The impact
on the Fund's financial statements, if any, is currently being assessed.

In addition, in September 2006, Statement of Financial Accounting Standards No.
157, "Fair Value Measurements" ("FAS 157"), was issued and is effective for
fiscal years beginning after November 15, 2007. FAS 157 defines fair value,
establishes a framework for measuring fair value and expands disclosures about
fair value measurements. Management is currently evaluating the implications of
FAS 157. At this time its impact on the Fund's financial statements has not been
determined.

(h) Reclassifications -- 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, $932,887 has been reclassified between accumulated net realized capital
losses allocated from the Series and accumulated

distributions in excess of net investment income, $263,111 has been reclassified
between accumulated net realized capital losses allocated from the Series and
paid-in capital in excess of par and $29,148 has been reclassified between
paid-in capital in excess of par and accumulated distributions in excess of net
investment income as a result of permanent differences attributable to foreign
currency transactions, net gains realized on the distribution of securities not
recognized for tax purposes, gains from the sale of stock of passive foreign
investment companies and basis adjustments on securities distributed in-kind.
These reclassifications have no effect on net assets or net asset values per
share.

2. Transactions with Affiliates:

On September 29, 2006, BlackRock, Inc. and Merrill Lynch & Co., Inc. ("Merrill
Lynch") combined Merrill Lynch's investment management business, Merrill Lynch
Investment Managers, L.P. ("MLIM"), and its affiliates with BlackRock, Inc. to
create a new independent company. Merrill Lynch has a 49.8% economic interest
and a 45% voting interest in the combined company and The PNC Financial Services
Group, Inc. ("PNC"), has approximately a 34% economic and voting interest. The
new company operates under the BlackRock name and is governed by a board of
directors with a majority of independent members.

On August 15, 2006, shareholders of the Fund approved a new Investment Advisory
Agreement for the Trust on behalf of the Series with BlackRock Advisors, Inc.,
an indirect, wholly owned subsidiary of BlackRock, Inc. BlackRock Advisors, Inc.
was recently reorganized into a limited liability company and renamed BlackRock
Advisors, LLC. The new Investment Advisory Agreement became effective on
September 29, 2006. Prior to September 29, 2006, Fund Asset Management, L.P.
("FAM") was the Trust's manager. The general partner of FAM is Princeton
Services, Inc. ("PSI"), an indirect, wholly owned subsidiary of Merrill Lynch,
which is the limited partner.

The Corporation has entered into an Administration Agreement with BlackRock
Advisors, LLC (the "Administrator"). 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. Prior to September 29,
2006, MLIM acted as the Fund's Administrator and was compensated at the same fee
rate. The Administrator (and previously 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) ("service fees") will
not exceed .65%. This arrangement has a one-year term and is renewable. For the
period January 1, 2006 to September 29, 2006, MLIM earned fees of $706,465, of
which $161,609 were waived. For the period September 30, 2006 to December 31,
2006, BlackRock Advisors, LLC earned fees of $259,569, none of which was waived.

The Corporation has also entered into separate Distribution Agreements and
Distribution Plans with FAM Distributors, Inc. ("FAMD") and BlackRock
Distributors, Inc. ("BDI") (collectively, the "Distributor"). FAMD is a wholly
owned subsidiary of Merrill Lynch Group, Inc. and BDI is an affiliate of
BlackRock, Inc.

Pursuant to the Distribution Plans adopted by the Corporation in accordance with
Rule 12b-1 under the Investment Company Act of 1940, the Fund pays the
Distributor an ongoing service fee with respect to Investor A Shares. The fees
are accrued daily and paid monthly at the annual rate of .25% based upon the
average daily net assets of Investor A Shares.

Pursuant to sub-agreements with each Distributor, broker-dealers, including
Merrill Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S"), a wholly owned
subsidiary of Merrill Lynch, and an affiliate of the Distributor, also provides
account maintenance services to the Fund. The ongoing service fee compensates
the Distributors and each broker-dealer (including MLPF&S) for providing account
maintenance services to Investor A shareholders.

Effective September 29, 2006, PFPC Inc., an indirect, wholly owned subsidiary of
PNC and an affiliate of the Administrator, became the Fund's transfer agent.
Prior to September 29, 2006, the Fund's transfer agent was Financial Data
Services, Inc. ("FDS"), a wholly owned subsidiary of Merrill Lynch.

Prior to September 29, 2006, certain officers and/or directors of the
Corporation were officers and/or directors of MLIM, PSI, FAMD, FDS, and/or
Merrill Lynch.

Commencing September 29, 2006, certain officers and/or directors of the
Corporation are officers and/or directors of BlackRock, Inc. or its affiliates.

3. Capital Share Transactions:

Net increase in net assets derived from capital share transactions was

4. Distributions to Shareholders:

31, 2006 and December 31, 2005 was as follows:

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

As of December 31, 2006, the components of accumulated earnings on a tax basis
were as follows:

- -------------------------------------------------------------------------------
Undistributed ordinary income--net ......................          $  2,221,768
Undistributed capital gains--net ........................               130,591
                                                                   ------------

*     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              BlackRock International Index Fund
Public Accounting Firm

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

We have audited the accompanying statement of assets and liabilities of
BlackRock International Index Fund (formerly Merrill Lynch International Index
Fund), one of the series constituting BlackRock Index Funds, Inc. (formerly
Merrill Lynch Index Funds) (the "Fund"), as of December 31, 2006, 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
BlackRock International Index Fund of BlackRock Index Funds, Inc. as of December
31, 2006, 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 accounting principles generally accepted in the United States of
America.

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 Global 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") markets, NASDAQ Capital
Market 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 markets are
valued at the last available asked price. Portfolio securities that are traded
both in the OTC markets 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. Options traded in the OTC market are valued at the last
asked price (options written) or the last bid price (options purchased). Swap
agreements are valued based upon quoted fair valuations received daily by the
Series 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 BlackRock Advisors, LLC
(the "Manager"), an indirect, wholly owned subsidiary of BlackRock, Inc.,
believes that this method no longer produces fair valuations. Valuation of other
short-term investment vehicles is generally based on the net asset value of the
underlying investment vehicle or amortized cost.

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 and certain fixed income securities, 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 are generally determined as of 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 will be valued
at their fair value as determined in good faith by the Trust's Board of Trustees
or by the Manager 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 financial futures contracts.
      Financial 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


        BLACKROCK INTERNATIONAL INDEX FUND      DECEMBER 31, 2006             27


Notes to Financial Statements (continued)      Master International Index Series

      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.

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 OTC 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


28      BLACKROCK INTERNATIONAL INDEX FUND      DECEMBER 31, 2006


Notes to Financial Statements (continued)      Master International Index Series

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 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.

(g) Recent accounting pronouncements -- In July 2006, the Financial Accounting
Standards Board ("FASB") issued Interpretation No. 48 ("FIN 48"), "Accounting
for Uncertainty in Income Taxes -- an interpretation of FASB Statement No. 109."
FIN 48 prescribes the minimum recognition threshold a tax position must meet in
connection with accounting for uncertainties in income tax positions taken or
expected to be taken by an entity including mutual funds before being measured
and recognized in the financial statements. Adoption of FIN 48 is required for
the last net asset value calculation in the first required financial statement
reporting period for fiscal years beginning after December 15, 2006. The impact
on the Series' financial statements, if any, is currently being assessed.

In addition, in September 2006, Statement of Financial Accounting Standards No.
157, "Fair Value Measurements" ("FAS 157"), was issued and is effective for
fiscal years beginning after November 15, 2007. FAS 157 defines fair value,
establishes a framework for measuring fair value and expands disclosures about
fair value measurements. Management is currently evaluating the implications of
FAS 157. At this time, its impact on the Series' financial statements has not
been determined.

2. Investment Advisory Agreement and Transactions with Affiliates:

On September 29, 2006, BlackRock, Inc. and Merrill Lynch & Co., Inc. ("Merrill
Lynch") combined Merrill Lynch's investment management business, Merrill Lynch
Investment Managers, L.P. ("MLIM"), and its affiliates including Fund Asset
Management, L.P. ("FAM"), with BlackRock, Inc. to create a new independent
company. Merrill Lynch has a 49.8% economic interest and a 45% voting interest
in the combined company and The PNC Financial Services Group, Inc. ("PNC"), has
approximately a 34% economic and voting interest. The new company operates under
the BlackRock name and is governed by a board of directors with a majority of
independent members.

On September 29, 2006, shareholders of the investors of the Series approved a
new Investment Advisory Agreement for the Trust with the Manager. BlackRock
Advisors, Inc. was recently reorganized into a limited liability company and
renamed BlackRock Advisors, LLC. The new Investment Advisory Agreement between
the Trust and the Manager became effective on September 29, 2006. Prior to
September 29, 2006, FAM was the Manager. The general partner of FAM is Princeton
Services, Inc. ("PSI"), an indirect, wholly owned subsidiary of Merrill Lynch,
which is the limited partner.

The Manager is responsible for the management of the Series' investments 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. The Manager (and previously 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. The reimbursements were as follows:

- --------------------------------------------------------------------------------
             For the Period                          For the Period
           January 1, 2006 to                    September 30, 2006 to
           September 29, 2006                      December 31, 2006
             Reimbursement                           Reimbursement
                by FAM                               by the Manager
- --------------------------------------------------------------------------------
               $52,657                                  $15,595
- --------------------------------------------------------------------------------

In addition, the Manager has entered into a sub-advisory agreement with
BlackRock Investment Management, LLC, an affiliate of the Manager, under which
the Manager pays the Sub-Advisor for services it provides a monthly fee that is
a percentage of the management fee paid by the Series to the Manager.

For the year ended December 31, 2006, the Series reimbursed FAM and the Manager
$10,377 and $3,750, respectively, for certain accounting services.


        BLACKROCK INTERNATIONAL INDEX FUND      DECEMBER 31, 2006             29


Notes to Financial Statements (concluded)      Master International Index Series

In addition, Merrill Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S"), an
affiliate of the Manager, received $37,152 in commissions on the execution of
portfolio security transactions for the Series for the year ended December 31,
2006.

Prior to September 29, 2006, certain officers and/or trustees of the Trust were
officers and/or directors of FAM, MLIM, PSI, and/or Merrill Lynch.

Commencing September 29, 2006, certain officers and/or trustees of the Trust are
officers and/or directors of BlackRock, Inc. or its affiliates.

3. Investments:

Purchases and sales (including in-kind redemptions) of investments, excluding
short-term securities, for the year ended December 31, 2006 were $320,252,993
and $143,844,935, respectively.

4. Commitments:

At December 31, 2006, the Series had entered into foreign exchange contracts, in
addition to the contracts listed on the Schedule of Investments, under which it
had agreed to buy various foreign currencies with an approximate value of
$2,177,000.

5. Short-Term Borrowings:

The Trust, on behalf of the Series, along with certain other funds managed by
the Manager and its affiliates (or 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.
On November 22, 2006, the credit agreement was renewed for one year under
substantially the same terms. The Series pays a commitment fee of .06% 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 .35% 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, 2006.

Report of Independent Registered               Master International Index Series
Public Accounting Firm

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

We have audited the accompanying statement of assets and liabilities, including
the 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, 2006, 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, 2006, by correspondence with the
custodian. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of Master
International Index Series of the Quantitative Master Series Trust as of
December 31, 2006, 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 accounting principles generally accepted in the United
States of America.

Disclosure of Investment Advisory Agreement

New BlackRock Investment Advisory Agreement -- Matters Considered by the Boards

The following disclosure appeared in the June 30, 2006 Semi-Annual Report of the
Fund and the Series and is the discussion referred to in "New BlackRock
Sub-Advisory Agreement -- Matters Considered by the Boards" below. The term
"Investment Adviser" as used herein refers to Fund Asset Management, L.P.

Merrill Lynch International Index Fund (the "Fund"), a series of Merrill Lynch
Index Funds, Inc. (the "Corporation"), is a "feeder" fund that invests all of
its assets in the Master International Index Series (the "Series") of
Quantitative Master Series Trust (the "Trust"), which has the same investment
objectives and strategies as the Fund. All investments are made at the Series
level.

In connection with the Transaction between Merrill Lynch and BlackRock, the
Board of Trustees of the Trust (the "trustees") considered a new investment
advisory agreement between the Trust, on behalf of Series, and BlackRock
Advisors, Inc. or its successor ("BlackRock Advisors"). If the Trust's New
Investment Advisory Agreement is approved by shareholders, then that agreement
will become effective upon the closing of the Transaction, which is expected in
the third quarter of 2006.

In addition, in connection with the Transaction, the Board of Directors of the
Corporation (the "directors") considered a new investment advisory agreement
(together with the new advisory agreement for the Trust, the "New Investment
Advisory Agreements") between the Corporation on behalf of the Fund and
BlackRock Advisors. If the Fund's New Investment Advisory Agreement is approved
by shareholders, then that agreement will become effective upon the closing of
the Transaction. Under a contractual arrangement between the Corporation on
behalf of the Fund and BlackRock Advisors, however, no management/advisory fee
will be charged to the Fund under the Fund's New Investment Advisory Agreement
so long as the Fund remains invested in the Series.

Each Board discussed the New Investment Advisory Agreements at telephonic and
in-person meetings held during April and May 2006. Each Board, including the
independent directors/trustees, approved the New Investment Advisory Agreements
on May 8, 2006.

To assist each Board in its consideration of the New Investment Advisory
Agreements, BlackRock provided materials and information about BlackRock,
including its financial condition and asset management capabilities and
organization, and Merrill Lynch provided materials and information about the
Transaction. The independent directors/trustees, through their independent legal
counsel, also requested and received additional information from Merrill Lynch
and BlackRock in connection with their consideration of the New Investment
Advisory Agreements. The additional information was provided in advance of the
May 2006 meeting. In addition, the independent directors/trustees consulted with
their counsel and counsel for the Corporation and the Trust on numerous
occasions, discussing, among other things, the legal standards and certain other
considerations relevant to each Board's deliberations.

At the Board meetings, each Board discussed with Merrill Lynch management and
certain BlackRock representatives the Transaction, its strategic rationale and
BlackRock's general plans and intentions regarding the Fund and the Series. At
these Board meetings, representatives of Merrill Lynch and BlackRock made
presentations to and responded to questions from each Board. Each Board also
inquired about the plans for and anticipated roles and responsibilities of
certain employees and officers of the Investment Adviser and certain affiliates
being transferred to BlackRock in connection with the Transaction. The
independent directors/trustees also conferred separately and with their counsel
about the Transaction and other matters related to the Transaction on a number
of occasions, including in connection with the April and May 2006 meetings.
After the presentations and after reviewing the written materials provided, the
independent directors/trustees met in executive sessions with their counsel to
consider the New Investment Advisory Agreements.

In connection with each Board's review of the New Investment Advisory
Agreements, Merrill Lynch and/or BlackRock advised the Board about a variety of
matters. The advice included the following, among other matters:

o     that there is not expected to be any diminution in the nature, quality and
      extent of services provided to the Fund and Series and their shareholders
      by BlackRock Advisors, including compliance services;

o     that operation of New BlackRock as an independent investment management
      firm will enhance its ability to attract and retain talented
      professionals;

o     that the Fund and the Series should benefit from having access to
      BlackRock's state of the art technology and risk management analytic
      tools, including investment tools, provided under the BlackRock
      Solutions(R) brand name;


32      BLACKROCK INTERNATIONAL INDEX FUND      DECEMBER 31, 2006


o     that BlackRock has no present intention to alter any applicable expense
      waivers or reimbursements currently in effect and, while it reserves the
      right to do so in the future, it would seek the approval of the Boards
      before making any changes;

o     that BlackRock and Merrill Lynch will enter into an agreement, for an
      initial three-year period and automatically renewable from year to year
      thereafter, in connection with the Transaction under which Merrill
      Lynch-affiliated broker-dealers will continue to offer the Fund as an
      investment product;

o     that BlackRock Advisors will have substantially the same access to the
      Merrill Lynch sales force when distributing shares of the Fund as is
      currently provided to the Investment Adviser and that other arrangements
      between the Investment Adviser and Merrill Lynch sales channels will be
      preserved;

o     that the Fund will have access to BlackRock's network of third party
      brokers, retirement plan platforms and registered investment advisers;

o     that in connection with the Transaction, Merrill Lynch and BlackRock have
      agreed to conduct, and use reasonable best efforts to cause their
      respective affiliates to conduct, their respective businesses in
      compliance with the conditions of Section 15(f) of the Investment Company
      Act of 1940 (the "1940 Act") in relation to any public funds advised by
      BlackRock or the Investment Adviser (or its affiliates), respectively; and

o     that Merrill Lynch and BlackRock would derive benefits from the
      Transaction and that, as a result, they have a different financial
      interest in the matters that were being considered than do Fund or Series
      shareholders.

Each Board considered the information provided by Merrill Lynch and BlackRock
above, and, among other factors, the following:

o     the potential benefits to the Fund and the Series shareholders from being
      part of a combined fund family with BlackRock-sponsored funds, including
      possible economies of scale and access to investment opportunities;

o     the potential for expanding  distribution of Fund shares through  improved
      access to third party distribution;

o     the  reputation,  financial  strength and  resources of BlackRock  and its
      investment  advisory  subsidiaries and the anticipated  financial strength
      and resources of New BlackRock;

o     the compliance policies and procedures of BlackRock Advisors;

o     the terms and conditions of the New Investment Advisory Agreements,
      including the fact that neither the schedule of the total advisory and
      administrative fees for the Fund nor the schedule of the total advisory
      fees of the Series will increase by virtue of either New Investment
      Advisory Agreement, but will remain the same;

o     that  each  Board  had  earlier  performed  a full  annual  review  of the
      investment advisory agreements currently in effect for the Series and Fund
      (the "Current Investment Advisory Agreements") as required by the 1940 Act
      and has  determined  that the  Investment  Adviser  has the  capabilities,
      resources   and   personnel   necessary   to  provide  the   advisory  and
      administrative services currently provided to the Fund and the Series; and
      that the advisory and/or  management fees paid by the Series,  taking into
      account any applicable agreed-upon fee waivers and breakpoints,  represent
      reasonable compensation to the Investment Adviser in light of the services
      provided, the costs to the Investment Adviser of providing those services,
      economies  of scale,  the fees and other  expenses  paid by similar  funds
      (including information provided by Lipper Inc. ["Lipper"]), and such other
      matters  as the Board  has  considered  relevant  in the  exercise  of its
      reasonable judgment; and

o     that Merrill Lynch agreed to pay all expenses of the Fund and the Series
      in connection with each Board's consideration of the New Investment
      Advisory Agreements and related agreements and all costs of shareholder
      approval of the New Investment Advisory Agreements and as a result neither
      the Fund nor the Series would bear any costs in obtaining shareholder
      approval of the New Investment Advisory Agreements.

Certain of these considerations are discussed in more detail below.

In its review of the New Investment Advisory Agreements, each Board assessed the
nature, scope and quality of the services to be provided to the Fund and the
Series by the personnel of BlackRock Advisors and its affiliates, including
administrative services, shareholder services, oversight of fund accounting,
marketing services and assistance in meeting legal and regulatory requirements.
In its review of the


        BLACKROCK INTERNATIONAL INDEX FUND      DECEMBER 31, 2006             33


Disclosure of Investment Advisory Agreement (continued)

New Investment Advisory Agreements, each Board also considered a range of
information in connection with its oversight of the services to be provided by
BlackRock Advisors and its affiliates. Among the matters considered were: (a)
fees (in addition to management fees) to be paid to BlackRock Advisors and its
affiliates by the Fund and the Series; (b) operating expenses of the Fund and
the Series paid to third parties; (c) the resources devoted to and compliance
reports relating to the investment objectives, policies and restrictions of the
Fund and the Series, and their compliance with their Codes of Ethics and
BlackRock Advisors' compliance policies and procedures; and (d) the nature, cost
and character of non-investment management services to be provided by BlackRock
Advisors and its affiliates.

In the period prior to the Board meetings to consider approval or renewal of the
Current Investment Advisory Agreements, each Board had requested and received
materials specifically relating to the Current Investment Advisory Agreements.
These materials included (a) information compiled by Lipper on the fees and
expenses and the investment performance of the Fund and the Series as compared
to a comparable group of funds as classified by Lipper; (b) a discussion by the
portfolio management team for the Series on investment strategies used by the
Series during its most recent fiscal year; (c) information on the profitability
to the Investment Adviser of the Current Investment Advisory Agreements and
other payments received by the Investment Adviser and its affiliates from the
Fund and the Series; and (d) information provided by the Investment Adviser
concerning services related to the valuation and pricing of portfolio holdings
of the Series, allocation of brokerage fees, portfolio turnover statistics, and
direct and indirect benefits to the Investment Adviser and its affiliates from
their relationship with the Fund and the Series.

In its deliberations, each Board considered information received in connection
with its most recent approval of the Current Investment Advisory Agreements, in
addition to information provided by BlackRock and BlackRock Advisors in
connection with its evaluation of the terms and conditions of the New Investment
Advisory Agreements. The directors/ trustees did not identify any particular
information that was all-important or controlling, and each director/trustee
attributed different weights to the various factors. Each Board, including a
majority of the independent directors/trustees, concluded that the terms of the
New Investment Advisory Agreements are appropriate, that the fees to be paid are
reasonable in light of the services to be provided to the Fund and the Series,
and that the New Investment Advisory Agreements should be approved and
recommended to shareholders.

Nature, Quality and Extent of Services Provided -- Each Board reviewed the
nature, extent and quality of services provided by the Investment Adviser,
including the investment advisory services and the resulting performance of the
Fund and the Series, as well as the nature, quality and extent of services
expected to be provided by BlackRock Advisors. Each Board focused primarily on
the Investment Adviser's investment advisory services and the investment
performance of the Fund and the Series, but also considered certain areas in
which both the Investment Adviser and the Fund/Series receive services as part
of the Merrill Lynch complex. Each Board compared the performance of the Fund
and the Series -- both including and excluding the effects of fees and expenses
- -- to the performance of a comparable group of funds, and the performance of a
relevant index or combination of indexes. While each Board reviews performance
data at least quarterly, consistent with the Investment Adviser's investment
goals, the Board attaches more importance to performance over relatively long
periods of time, typically three to five years.

In evaluating the nature, quality and extent of the services to be provided by
BlackRock Advisors under the New Investment Advisory Agreements, each Board
considered, among other things, the expected impact of the Transaction on the
operations, facilities, organization and personnel of BlackRock Advisors and how
it would affect the Fund and the Series; the ability of BlackRock Advisors to
perform its duties after the Transaction; and any anticipated changes to the
current investment and other practices of the Fund and the Series.

Each Board was given information with respect to the potential benefits to the
Fund and the Series and their shareholders from having access to BlackRock's
state of the art technology and risk management analytic tools, including the
investment tools provided under the BlackRock Solutions brand name.

Each Board was advised that, as a result of Merrill Lynch's equity interest in
BlackRock after the Transaction, the Fund and the Series will continue to be
subject to restrictions concerning certain transactions involving Merrill Lynch
affiliates (for example, transactions with a Merrill Lynch broker-dealer acting
as principal) absent revised or new regulatory relief. Each Board was advised
that a revision of existing regulatory relief with respect to these restrictions
was being sought from the Securities and Exchange Commission and was advised of


34      BLACKROCK INTERNATIONAL INDEX FUND      DECEMBER 31, 2006


the possibility of receipt of such revised  regulatory  relief.  There can be no
assurance that such relief will be obtained.

Based on its review of the materials provided and the assurances they had
received from the management of Merrill Lynch and of BlackRock, each Board
determined that the nature and quality of services to be provided to the Fund
and the Series under each New Investment Advisory Agreement were expected to be
as good or better than that provided under the Current Investment Advisory
Agreement of the Series. It was noted, however, that it is expected that there
will be changes in personnel following the Transaction and the combination of
the operations of the Investment Adviser and its affiliates with those of
BlackRock. Each Board noted that if current portfolio managers or other
personnel cease to be available, the Board would consider all available options,
which could include seeking the investment advisory or other services of
BlackRock affiliates. Accordingly, each Board concluded that, overall, it was
satisfied at the present time with assurances from BlackRock and BlackRock
Advisors as to the expected nature, extent and quality of the services to be
provided to the Fund/Series under the New Investment Advisory Agreement of the
Series.

Costs of Services Provided and Profitability -- It was noted that, in
conjunction with the recent review of the Current Investment Advisory Agreement
of the Series, each Board had received, among other things, a report from Lipper
comparing the fees, expenses and performance of the Fund and the Series to those
of a peer group selected by Lipper, and information as to the fees charged by
the Investment Adviser or its affiliates to other registered investment company
clients for investment management services. Each Board reviewed the contractual
management fee rate and actual management fee rate of the Fund/Series as a
percentage of total assets at common asset levels -- the actual rate includes
advisory and the effects of any fee waivers and, for the Fund, administrative
service fees -- compared to the other funds in its Lipper category. They also
compared the total expenses of the Fund and the Series to those of other
comparable funds. The information showed that the Fund and the Series had fees
and expenses within the range of fees and expenses of comparable funds. Each
Board considered the services to be provided by and the fees to be charged by
BlackRock Advisors to other funds with similar investment mandates and noted
that the fees charged by BlackRock Advisors in those cases, including fee
waivers and expense reimbursements, were generally comparable to those for the
Fund and the Series. Each Board concluded that the management fee and fee rate
and overall expense ratio of the Fund and the Series are reasonable compared to
those of other comparable funds.

In evaluating the costs of the services to be provided by BlackRock Advisors
under the New Investment Advisory Agreements, each Board considered, among other
things, whether advisory and administrative fees or other expenses would change
as a result of the Transaction. Based on its review of the materials provided
and the fact that each New Investment Advisory Agreement, as well as a new
administrative agreement between the Corporation on behalf of the Fund and
BlackRock Advisors as administrator, is substantially similar to its
corresponding current agreement in all material respects, including the rate of
compensation, each Board determined that the Transaction should not increase the
total fees payable, including any fee waivers and expense reimbursements, for
advisory and administrative services. Each Board noted that it was not possible
to predict with certainty New BlackRock's future profitability from its
relationship with the Fund and the Series.

Each Board discussed with BlackRock Advisors its general methodology to be used
in determining New BlackRock's profitability with respect to its relationship
with the Fund and the Series. Each Board noted that it expects to receive
profitability information from New BlackRock on at least an annual basis and
thus be in a position to evaluate whether any adjustments in fees and/or fee
breakpoints of the Fund or Series would be appropriate.

Fees and Economies of Scale -- Each Board considered the extent to which
economies of scale might be realized as the assets of the Fund and the Series
increase and whether there should be changes in the management fee rate or
structure in order to enable the Fund and the Series to participate in these
economies of scale. Each Board determined that changes were not currently
necessary and that the Fund and the Series appropriately participated in these
economies of scale.

In reviewing the Transaction, each Board considered, among other things, whether
advisory and administrative fees or other expenses would change as a result of
the Transaction. Based on the fact that the New Investment Advisory Agreements
and the new administrative agreement are substantially similar to the Current
Investment Advisory Agreements and the current administrative agreement in all
material respects, including the rates of compensation, each Board determined
that as a result of the Transaction, neither the total advisory and
administrative fees of the Fund nor the total advisory fees of the Series would
be higher than the


        BLACKROCK INTERNATIONAL INDEX FUND      DECEMBER 31, 2006             35


Disclosure of Investment Advisory Agreement (concluded)

fees under the Current Investment Advisory Agreements and administrative
agreement. Each Board noted that in conjunction with its most recent
deliberations concerning the Current Investment Advisory Agreements, the Board
had determined that the total fees for advisory and administrative services for
the Fund and the total fees for advisory services for the Series were reasonable
in light of the services provided. It was noted that in conjunction with the
recent review of the Current Investment Advisory Agreement of the Series, each
Board had received, among other things, a report from Lipper comparing the fees,
expenses and performance to those of a peer group selected by Lipper, and
information as to the fees charged by the Investment Adviser to other registered
investment company clients for investment management services. Each Board
concluded that, because the rate for advisory services for the Series and the
rates for advisory and administrative services for the Fund would be no higher
than current fee rates, the proposed management fee structures, including any
fee waivers, were reasonable and that no additional changes were currently
necessary.

Fall-Out Benefits -- In evaluating the fall-out benefits to be received by
BlackRock Advisors under each New Investment Advisory Agreement, each Board
considered whether the Transaction would have an impact on the fall-out benefits
received by the Investment Adviser by virtue of the Current Investment Advisory
Agreements. Based on its review of the materials provided, including materials
received in connection with their most recent approval of each Current
Investment Advisory Agreement, and its discussions with management of the
Investment Adviser and BlackRock, each Board determined that those benefits
could include increased ability for BlackRock to distribute shares of its funds
and other investment products and to obtain research services using portfolio
transaction brokerage commissions. The Fund's Board also considered possible
benefits stemming from the proposal that PFPC Financial Services, an affiliate
of BlackRock, serve as transfer agent for the Fund following the Transaction.
Each Board noted that any benefits were difficult to quantify with certainty at
this time, and indicated that they would continue to evaluate them going
forward.

Investment Performance -- Each Board considered investment performance for the
Fund and the Series. Each Board compared the performance of the Fund and the
Series -- both including and excluding the effects of fees and expenses -- to
the performance of a comparable group of funds, and the performance of a
relevant index or combination of indexes. The comparative information received
from Lipper showed Series performance at various levels within the range of
performance of comparable funds over different time periods. While each Board
reviews performance data at least quarterly, consistent with the Investment
Adviser's investment goals, the Board attaches more importance over relatively
long periods of time, typically three to five years. Each Board believed the
performance of the Fund and the Series was satisfactory. Also, each Board took
into account the investment performance of funds currently advised by BlackRock
Advisors. Each Board considered comparative information from Lipper which showed
that the performance of the funds advised by BlackRock Advisors was within the
range of performance of comparable funds over different time periods. Each Board
noted BlackRock's considerable investment management experience and
capabilities, but was unable to predict what effect, if any, consummation of the
Transaction would have on the future performance of the Fund and the Series.

Conclusion -- After the independent directors of the Corporation, on behalf of
the Fund, and trustees of the Trust, on behalf of the Series, deliberated in
executive session, each entire Board, including the independent
directors/trustees, approved the New Investment Advisory Agreements, concluding
that the advisory fee rates were reasonable in relation to the services provided
and that the New Investment Advisory Agreements were in the best interests of
the shareholders. In approving the New Investment Advisory Agreements, each
Board noted that it anticipated reviewing the continuance of the agreements in
advance of the expiration of the initial two-year period.

Contingent BlackRock Sub-Advisory Agreements -- Matters Considered by the Boards

At the telephonic and in-person meetings held during April and May 2006 at which
each Board discussed and approved the New Investment Advisory Agreements, the
Board of Directors of Merrill Lynch Index Funds, Inc. on behalf of the Fund,
including the independent directors, and the Board of Trustees of the Trust on
behalf of the Series, including the independent trustees, also discussed and
approved contingent sub-advisory agreements (the "Contingent Sub-Advisory
Agreements") between the Investment Adviser and BlackRock Advisors (the
"BlackRock Sub-Adviser"). The Contingent SubAdvisory Agreements are intended to
ensure that the Fund and the Series operate with efficient portfolio management
services until the closing of the Transaction, in the event that the Boards deem
it necessary and in the best interests of the Fund and its shareholders, or the
Series and its shareholders, that the BlackRock Sub-Adviser assist in managing
the


36      BLACKROCK INTERNATIONAL INDEX FUND      DECEMBER 31, 2006


operations of the Fund or the Series during the interim period until the closing
of the Transaction. If shareholders approve the Contingent Sub-Advisory
Agreements, they will take effect only upon recommendation from the Investment
Adviser and upon subsequent approval of the Boards in the period up to the
closing of the Transaction. The effectiveness of each Contingent Sub-Advisory
Agreement, therefore, would be contingent on further Board approval after
shareholders approve it. Pursuant to each Contingent Sub-Advisory Agreement, the
BlackRock Sub-Adviser would receive a monthly fee from the Investment Adviser
equal to 50% of the advisory fee received by the Adviser. The Investment Adviser
would pay the BlackRock Sub-Adviser out of its own resources. There would be no
increase in Fund or Series expenses as a result of either Contingent
Sub-Advisory Agreement.

In making its approval at the May in-person meeting, each Board considered the
Contingent Sub-Advisory Agreements in conjunction with the New Investment
Advisory Agreements and reviewed the same information and factors discussed
above. Each Board also considered, in conjunction with the Contingent
Sub-Advisory Agreements, the necessity of ensuring that the Fund and the Series
operate with effective management services until the closing of the Transaction.
In reviewing the sub-advisory fee rate provided in each Contingent Sub-Advisory
Agreement, each Board took note of the fact that both the Investment Adviser and
the BlackRock Sub-Adviser would have significant responsibilities under their
respective advisory agreements. The Investment Adviser would remain responsible
for oversight of the operations and administration of the Fund/Series and the
BlackRock Sub-Adviser would provide advisory services to the Fund/Series under
each Contingent Sub-Advisory Agreement. Each Board also took into account the
expected short duration of the term of any Contingent Sub-Advisory Agreement and
the fact that total advisory fees paid by the Fund and the Series would not
increase as a result of either Contingent Sub-Advisory Agreement. Under all of
the circumstances, each Board concluded that it was a reasonable allocation of
fees for the BlackRock Sub-Adviser to receive 50% of the advisory fee paid by
the Fund or Series to the Investment Adviser.

After the independent directors/trustees deliberated in executive session, each
entire Board, including the independent directors/trustees, approved each
Contingent Sub-Advisory Agreement, concluding that the advisory fee was
reasonable in relation to the services provided and that the Contingent
Sub-Advisory Agreement was in the best interests of shareholders.

Disclosure of Sub-Advisory Agreement

New BlackRock Sub-Advisory Agreement -- Matters Considered by the Boards

At an in-person meeting held on August 16-17, 2006, the Board of Directors of
BlackRock Index Funds, Inc. (the "Corporation") and the Board of Trustees of
Quantitative Master Series Trust (the "Trust"), including the independent
directors/trustees, discussed and approved the sub-advisory agreement between
BlackRock Advisors, LLC (previously organized as BlackRock Advisors, Inc.)
("BlackRock Advisors") and BlackRock Investment Management, LLC, an affiliate
(the "Sub-Adviser") (the "BlackRock Sub-Advisory Agreement"). The BlackRock
Sub-Advisory Agreement became effective on September 29, 2006, at the same time
the New Investment Advisory Agreement with BlackRock Advisors (which had been
approved by the Fund's shareholders) became effective.

Pursuant to the BlackRock Sub-Advisory Agreement, the Sub-Adviser receives a
monthly fee from BlackRock Advisors at an annual rate equal to 74% of the
advisory fee received by BlackRock Advisors from the Series. BlackRock Advisors
pays the Sub-Adviser out of its own resources, and there is no increase in Fund
or Series expenses as a result of the BlackRock Sub-Advisory Agreement.

In approving the BlackRock Sub-Advisory Agreement at the August 2006 in-person
meeting, the Boards reviewed their considerations in connection with their
approval of the New Investment Advisory Agreement in May 2006. The Boards relied
on the same information and considered the same factors as those discussed above
in connection with the approval of the New Investment Advisory Agreement. In
reviewing the sub-advisory fee rate provided for in the BlackRock Sub-Advisory
Agreement, the Boards noted the fact that both BlackRock Advisors and the
Sub-Adviser have significant responsibilities under their respective advisory
agreements. Under the New Investment Advisory Agreement, BlackRock Advisors
remains responsible for the overall management of the Fund and the Series and
for oversight of the Fund's and the Series' operations and administration. Under
the BlackRock Sub-Advisory Agreement, the Sub-Adviser provides advisory services
to the Series and is responsible for the day-to-day management of the Series'
portfolio. The Boards also took into account the fact that there is no increase
in total advisory fees paid by the Fund or the Series as a result of the
BlackRock Sub-Advisory Agreement. Based on its considerations, each Board
concluded that it was a reasonable allocation of fees for the Sub-Adviser to
receive a fee at an annual rate equal to 74% of the advisory fee paid by the
Series to BlackRock Advisors.

After the independent directors/trustees deliberated in executive session, the
entire Board of the Corporation and the entire Board of the Trust, including the
independent directors/ trustees, approved the BlackRock Sub-Advisory Agreement,
concluding that the sub-advisory fee was reasonable in relation to the services
provided and that the BlackRock Sub-Advisory Agreement was in the best interests
of Fund shareholders.

BlackRock Privacy Principles

BlackRock is committed to maintaining the privacy of its current and former fund
investors and individual clients (collectively, "Clients") and to safeguarding
their nonpublic personal information. The following information is provided to
help you understand what personal information BlackRock collects, how we protect
that information and why in certain cases we share such information with select
parties.

If you are located in a jurisdiction where specific laws, rules or regulations
require BlackRock to provide you with additional or different privacy-related
rights beyond what is set forth below, then BlackRock will comply with those
specific laws, rules or regulations.

BlackRock obtains or verifies personal nonpublic information from and about you
from different sources, including the following: (i) information we receive from
you or, if applicable, your financial intermediary, on applications, forms or
other documents; (ii) information about your transactions with us, our
affiliates, or others; (iii) information we receive from a consumer reporting
agency; and (iv) from visits to our Web sites.

BlackRock does not sell or disclose to nonaffiliated third parties any nonpublic
personal information about its Clients, except as permitted by law or as is
necessary to service Client accounts. These nonaffiliated third parties are
required to protect the confidentiality and security of this information and to
use it only for its intended purpose.

We may share information with our affiliates to service your account or to
provide you with information about other BlackRock products or services that may
be of interest to you. In addition, BlackRock restricts access to nonpublic
personal information about its Clients to those BlackRock employees with a
legitimate business need for the information. BlackRock maintains physical,
electronic and procedural safeguards that are designed to protect the nonpublic
personal information of its Clients, including procedures relating to the proper
storage and disposal of such information.

         (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.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM ON DETAILED SCHEDULE OF
INVESTMENTS

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

We have audited, in accordance with the standards of the Public Company
Accounting Oversight Board (United States), the financial statements of Master
International Index Series (the "Series"), one of the portfolios constituting
the Quantitative Master Series Trust (the "Trust"), as of December 31, 2006, and
for the year then ended and have issued our report thereon dated February 26,
2007 which report and financial statements are included in Item 1 of this
Certified Shareholder Report on Form N-CSR. Our audit also included the Series'
schedule of investments in securities (the "Schedule") as of December 31, 2006
appearing in Item 6 of this Form N-CSR. This Schedule is the responsibility of
the Trust's management. Our responsibility is to express an opinion based on our

relation to the basic financial statements taken as a whole of the Series

set forth therein.

Item 11 - Controls and Procedures

11(a) - The registrant's certifying officers have reasonably designed such

        disclosure controls and procedures to ensure material information
        relating to the registrant is made known to us by others particularly
        during the period in which this report is being prepared. The
        registrant's certifying officers have determined that the registrant's
        disclosure controls and procedures are effective based on our evaluation
        of these controls and procedures as of a date within 90 days prior to
        the filing date of this report.

11(b) - As of September 29, 2006, with the conclusion of the combination of

        Merrill Lynch's asset management business with BlackRock, the registrant
        was migrated to BlackRock's trading and compliance monitoring systems,
        and various personnel changes occurred. In conjunction with these
        business improvements, there were no changes in the registrants internal
        control over financial reporting (as defined in Rule 30a-3(d) under Act
        (17 CFR 270.30a-3(d)) that occurred during the last fiscal half-year of
        the period covered by this report that has materially affected, or is
        reasonably likely to affect, the registrant's internal control over
        financial reporting.
