SEPTEMBER 3, 1997     
 
                        MERRILL LYNCH INDEX FUNDS, INC.
  P.O. BOX 9011, PRINCETON, NEW JERSEY 08543-9011 . PHONE NO. (609) 282-2800
 
                               ----------------
   
  Merrill Lynch Index Funds, Inc. (the "Corporation") currently consists of
four portfolios or series: Merrill Lynch S&P 500 Index Fund ("S&P 500 Index
Fund"), Merrill Lynch Small Cap Index Fund ("Small Cap Index Fund"), Merrill
Lynch Aggregate Bond Index Fund ("Aggregate Bond Index Fund") and Merrill
Lynch International Index Fund ("International Index Fund") (collectively, the
"Funds," and each, a "Fund"). Each Fund is a non-diversified mutual fund whose
investment objective is to provide investment results that, before expenses,
seek to replicate the total return (i.e., the combination of capital changes
and income) of a securities index that has been selected as a proxy for the
performance of a selected market segment. The index is subject to change if,
in the Directors' judgment, a different index would serve as a better proxy
for such market segment. Each Fund will seek to achieve its objective by
investing all of its assets in the series (collectively, the "Series," and
each, a "Series") of Merrill Lynch Index Trust (the "Trust") that has the same
investment objective as the Fund. Each Fund's investment experience will
correspond directly to the investment experience of the respective Series in
which it invests. There can be no assurance that the investment objectives of
the Funds will be achieved. For more information on the Funds' and the Series'
investment objectives and policies, see "Investment Objectives and Policies"
on page 6.     
 
                               ----------------
 
  Each Fund offers two classes of shares, Class A shares and Class D shares.
Class A shares of each Fund are offered at a price equal to the next
determined net asset value per share without the imposition of any front-end
or deferred sales charge, and are not subject to any ongoing account
maintenance or distribution fee. Distribution of Class A shares of each Fund
is limited to certain eligible investors. Class D shares of each Fund are
offered at a price equal to the next determined net asset value per share
without the imposition of any front-end or deferred sales charge and are not
subject to any ongoing distribution fee, but are subject to an ongoing account
maintenance fee at an annual rate of 0.25% of average daily net assets.
 
                               ----------------
   
  Shares may be purchased directly from Merrill Lynch Funds Distributor, Inc.
(the "Distributor"), P.O. Box 9081, Princeton, New Jersey 08543-9081 (609)
282-2800, which has entered into a dealer agreement with Merrill Lynch,
Pierce, Fenner & Smith Incorporated ("Merrill Lynch"). Shareholders may redeem
their shares at any time at the next determined net asset value. The minimum
initial purchase is $1,000 and the minimum subsequent purchase is $50, except
that for retirement plans the minimum initial investment is $100 and the
minimum subsequent purchase is $1. Merrill Lynch may charge its customers a
processing fee (presently $5.35) for confirming purchases and repurchases.
Purchases and redemptions directly through the Funds' transfer agent are not
subject to processing fees. See "Purchase of Shares" and "Redemption of
Shares."

  THESE SECURITIES HAVE  NOT BEEN APPROVED OR DISAPPROVED  BY THE SECURITIES

       COMMISSION  PASSED  UPON  THE   ACCURACY  OR  ADEQUACY  OF  THIS
         PROSPECTUS.   ANY  REPRESENTATION  TO  THE  CONTRARY   IS  A

  This Prospectus is a concise statement of information about the Funds that
is relevant to making an investment in the Funds. This Prospectus should be
retained for future reference. A statement containing additional information
about the Funds, dated September 3, 1997 (the "Statement of Additional
Information"), has been filed with the Securities and Exchange Commission and
is available, without charge, by calling or by writing the Funds at the above
telephone number or address. The Statement of Additional Information is hereby
incorporated by reference into this Prospectus.

                                   FEE TABLE
   
  The following table provides a general comparison of expenses, both recurring
and non-recurring, relating to shares of the Funds and the Series. For purposes
of this table, expenses allocated from the Series in which each Fund invests
are treated as if they were expenses of that Fund, since that is their
practical effect. It is expected that there will be little duplication of
expenses by the Funds and the Series, and that, accordingly, the combined per
share expenses of each Fund and corresponding Series should not be
significantly greater than the expenses of each Fund alone would be if, instead
of investing in shares of the Series, the Fund retained an investment adviser
and invested directly in the types of securities held by the Series.

  The foregoing Fee Table is intended to assist investors in understanding the
costs and expenses that a shareholder in each class of each Fund will bear
directly or indirectly. The expenses set forth under "Other Expenses" are based
on estimated amounts through the end of a Series' and a Fund's first full
fiscal year on an annualized basis.
   
  The example set forth above assumes reinvestment of all dividends and
distributions and utilizes a 5% annual rate of return as mandated by Securities
and Exchange Commission regulations. THE EXAMPLE SHOULD NOT BE CONSIDERED A
REPRESENTATION OF PAST OR FUTURE EXPENSES OR ANNUAL RATE OF RETURN, AND ACTUAL
EXPENSES OR ANNUAL RATE OF RETURN MAY BE MORE OR LESS THAN THOSE ASSUMED FOR
PURPOSES OF THE EXAMPLE. Merrill Lynch may charge its customers a processing
fee (presently $5.35) for confirming purchases and repurchases. Purchases and
redemptions directly through the Funds' transfer agent are not subject to the
processing fee. See "Purchase of Shares" and "Redemption of Shares."

                       INVESTMENT OBJECTIVES AND POLICIES
   
  The Corporation currently consists of four series: S&P 500 Index Fund, Small
Cap Index Fund, Aggregate Bond Index Fund and International Index Fund. Each
Fund is a non-diversified mutual fund whose investment objective is to provide
investment results that, before expenses, seek to replicate the total return
(i.e., the combination of capital changes and income) of a specified securities
index. Each Fund will seek to achieve its objective by investing all of its
assets in the series of Merrill Lynch Index Trust that has the same investment
objective as the Fund. Each Fund's investment experience will correspond
directly to the investment experience of the respective Series in which it
invests. There can be no assurance that the investment objectives of the Funds
will be achieved.     
 
  The Funds' and Series' investment objectives are not fundamental policies,
and may be changed by the Directors of the Corporation and the Trustees of the
Trust, respectively, without shareholder approval. THE TRUSTEES AND THE
DIRECTORS MAY ALSO CHANGE THE TARGET INDEX OF ANY RESPECTIVE SERIES AND FUND IF
THEY CONSIDER THAT A DIFFERENT INDEX WOULD FACILITATE THE MANAGEMENT OF THE
SERIES AND FUND IN A MANNER WHICH BETTER ENABLES THE FUND AND SERIES TO SEEK TO
REPLICATE THE TOTAL RETURN OF THE MARKET SEGMENT REPRESENTED BY THE CURRENT
INDEX.
 
STRUCTURE OF THE FUNDS AND THE SERIES
 
  Unlike many other mutual funds, which directly acquire and manage their own
portfolio securities, each Fund seeks to achieve its investment objective by
investing all of its assets in the corresponding Series of the Trust. Each
Series is a separate series of a registered investment company with the same
investment objective as its corresponding investing Fund. Because the Funds
will not invest in any securities other than shares of the respective Series,
investors in the Funds will acquire an indirect interest in the Series.
   
  In addition to selling their shares to the Funds, the Series may sell their
shares to other mutual funds and institutional investors. All investors in the
Series invest on the same terms and conditions and pay a proportionate share of
the Series' expenses. However, other investors in the Series may sell their
shares at prices different from those of the Funds as a result of the
imposition of sales charges or different operating expenses. Therefore,
investors in the Funds should be aware that these differences may result in
different returns experienced by the various entities investing in the Series.
Information concerning other holders of shares of the Series is available from
Merrill Lynch Financial Data Services, Inc. ("MLFDS" or the "Transfer Agent")
by calling 1-800-MER-FUND.     
 
  The Board of Directors of the Corporation believes that this structure may
enable the Funds to benefit from certain economies of scale. This view is based
on the premise that (i) certain of the expenses of managing an investment
portfolio that seeks to replicate the total return of a securities index are
relatively fixed so that a larger investment portfolio may achieve a lower
ratio of operating expenses to net assets and (ii) a larger investment
portfolio may be able to reduce certain securities transaction costs to the
extent that contributions to and redemptions from the investment portfolio from
different investing entities may offset each other and thus produce a lower net
cash flow.
 
  A Fund's investment in a Series may be withdrawn by the Board of Directors at
any time if the Board determines that it is in the best interests of the Fund
to do so. If any such withdrawal were made, the Board would consider what
action might be taken, including the investment of all of the assets of the
Fund in
 
                                       6
<PAGE>
 
another pooled investment entity having the same investment objective as the
Fund or the retaining of an investment adviser to manage the Fund's assets
directly in accordance with the investment objective of the Fund. The inability
to find another such pooled entity or equivalent investment management could
have a significant impact on the investments of the Fund's shareholders.
 
  Investors in the Funds should be aware that smaller entities investing in the
Series may be materially affected by the actions of larger entities investing
in the Series. For example, investors in the Series holding larger positions
than the Funds could have greater voting power and effective voting control
over the operations of the Series. Changes in the investment objective,
policies or restrictions of a Series might cause a Fund to have difficulty in
finding a substitute Series or equivalent investment management and might cause
it to redeem its shares of the Series, and such a redemption could result in a
distribution in kind of portfolio securities held by the Series, instead of
cash. If securities were distributed to a Fund, and the Fund desired to convert
the securities to cash, it would incur brokerage, tax or other charges in
converting securities to cash. In addition, such a distribution in kind might
result in a less diversified portfolio of investments of a Fund. These
possibilities also exist for traditionally structured funds which have large or
institutional investors who may withdraw from the fund.
 
  Whenever a Fund is requested to vote on matters pertaining to a Series, the
Fund will hold a meeting of shareholders, and the Fund's votes with respect to
the Series will all be cast in the same proportion as the shares of the Fund
for which voting instructions are received.
   
S&P 500 INDEX FUND     
   
  The investment objective of the S&P 500 Index Fund is to provide investment
results that, before expenses, seek to replicate the total return (i.e., the
combination of capital changes and income) of the Standard & Poor's (R) 500
Composite Stock Price Index (the "S&P 500"). There can be no assurance that the
investment objective of the Fund will be achieved.     
   
  The Fund seeks to achieve its investment objective by investing all of its
assets in the Merrill Lynch S&P 500 Index Series of the Trust ("S&P 500 Index
Series"), which has the same investment objective as the Fund. The following is
a description of the investment policies of the S&P 500 Index Series.     
   
  In seeking to replicate the total return of the S&P 500, Merrill Lynch Asset
Management, L.P. ("MLAM" or the "Manager") generally will allocate the S&P 500
Index Series' investments among common stocks in approximately the same
weightings as the S&P 500. In addition, the Manager may use options and futures
contracts and other types of financial instruments relating to all or a portion
of the S&P 500. The S&P 500 Index Series may also engage in securities lending
and index arbitrage. See "Other Types of Investments and Investment
Techniques."     
 
  The S&P 500 is composed of the common stocks of 500 large capitalization
companies from various industrial sectors, most of which are listed on the New
York Stock Exchange Inc. A company's stock market capitalization is the total
market value of its outstanding shares. The S&P 500 represents a significant
portion of the market value of all common stocks publicly traded in the United
States.

SMALL CAP INDEX FUND     
   
  The investment objective of the Small Cap Index Fund is to provide investment
results that, before expenses, seek to replicate the total return (i.e., the
combination of capital changes and income) of the Russell 2000 (R) Index (the
"Russell 2000"). There can be no assurance that the investment objective of the
Fund will be achieved.     
   
  The Fund seeks to achieve its investment objective by investing all of its
assets in the Merrill Lynch Small Cap Index Series of the Trust ("Small Cap
Index Series"), which has the same investment objective as the Fund. The
following is a description of the investment policies of the Small Cap Index
Series.     
   
  In seeking to replicate the total return of the Russell 2000, the Manager may
not allocate the Small Cap Index Series' investments among all of the common
stocks in the Russell 2000, or in the same weightings as the Russell 2000.
Instead, the Small Cap Index Series may invest in a statistically selected
sample of the stocks included in the Russell 2000 and other types of financial
instruments. The Manager may use options and futures contracts and other types
of financial instruments relating to all or a portion of the Russell 2000. The
investments to be included in the Small Cap Index Series will be selected so
that the market capitalizations, industry weightings and other fundamental
characteristics of the stocks, and of the stocks underlying or otherwise
related to the foregoing financial instruments, closely approximate those same
factors in the Russell 2000, with the objective of reducing the selected
investment portfolio's deviation from the performance of the Russell 2000 (this
deviation is referred to as "tracking error"). The Small Cap Index Series may
also engage in securities lending and index arbitrage. See "Other Types of
Investments and Investment Techniques."     
 
  The Russell 2000 is composed of approximately 2,000 smaller-capitalization
common stocks from various industrial sectors. A company's stock market
capitalization is the total market value of its outstanding shares.
   
AGGREGATE BOND INDEX FUND     
   
  The investment objective of the Aggregate Bond Index Fund is to provide
investment results that, before expenses, seek to replicate the total return
(i.e., the combination of capital changes and income) of the Lehman Brothers
Aggregate Bond Index (the "Aggregate Bond Index"). There can be no assurance
that the investment objective of the Fund will be achieved.     
   
  The Fund seeks to achieve its investment objective by investing all of its
assets in the Merrill Lynch Aggregate Bond Index Series of the Trust
("Aggregate Bond Index Series"), which has the same investment objective as the
Fund. The following is a description of the investment policies of the
Aggregate Bond Index Series.     
   
  In seeking to replicate the total return of the Aggregate Bond Index, the
Manager may not allocate the Aggregate Bond Index Series' investments among all
of the fixed-income securities in the Aggregate Bond Index, or in the same
weightings as the Aggregate Bond Index. Instead, the Aggregate Bond Index
Series may invest in a statistically selected sample of fixed-income securities
and other types of financial instruments. The Manager may use options and
futures contracts and other types of financial instruments relating to all or a
portion of the Aggregate Bond Index. The investments to be included in the
Aggregate Bond Index Series will be selected with the objective of reducing the
selected investment portfolio's deviation from the performance of the Aggregate
Bond Index (tracking error). The Aggregate Bond Index Series may, from time to
time, substitute a different type of bond for one included in the Aggregate
Bond Index. Substitution may result in levels of interest rate, credit or
prepayment risks that differ from the levels of risks on the securities     
 
                                       8
<PAGE>
 
   
composing the Aggregate Bond Index. See "Risk Factors--Investments in Fixed-
Income Securities." The Aggregate Bond Index Series may also engage in
securities lending and index arbitrage. See "Other Types of Investments and
Investment Techniques."     
   
  The Aggregate Bond Index is composed primarily of dollar-denominated
investment grade fixed-income securities in the following classes: U.S.
Treasury and agency securities, U.S. corporate bonds, foreign corporate bonds,
foreign sovereign debt (debt securities issued or guaranteed by foreign
governments and governmental agencies), supranational debt (debt securities
issued by entities, such as the World Bank, constituted by the governments of
several countries to promote economic development) and mortgage-backed
securities with maturities greater than one year. Corporate bonds contained in
the Aggregate Bond Index represent issuers from various industrial sectors.
       
  The Aggregate Bond Index Series may invest in U.S. Treasury bills, notes and
bonds and other "full faith and credit" obligations of the U.S. Government. The
Aggregate Bond Index Series may also invest in U.S. Government agency
securities, which are debt obligations issued or guaranteed by agencies or
instrumentalities of the U.S. Government. "Agency" securities may not be backed
by the "full faith and credit" of the U.S. Government. U.S. Government agencies
may include the Federal Farm Credit Bank, the Resolution Trust Corporation and
the Government National Mortgage Association. "Agency" obligations are not
explicitly guaranteed by the U.S. Government and so are perceived as somewhat
riskier than comparable Treasury bonds.     
   
  The Aggregate Bond Index Series' corporate fixed-income securities will be
primarily of investment grade quality--i.e., those rated at least Baa3 by
Moody's Investors Service, Inc. ("Moody's") or BBB- by Standard & Poor's
Ratings Group ("S&P"), the equivalent by another nationally recognized
statistical rating organization ("NRSRO") or, if unrated, of equal quality in
the opinion of the Manager. Corporate fixed-income securities ranked in the
fourth highest rating category, while considered "investment grade", have more
speculative characteristics and are more likely to be downgraded than
securities rated in the three highest ratings categories. In the event that the
rating of a security in the Aggregate Bond Index Series is lowered below Baa or
BBB, the Aggregate Bond Index Series may continue to hold the security. Such
securities rated below investment grade are considered to be speculative with
respect to the issuer's capacity to pay interest and repay principal in
accordance with the terms of the obligation. Descriptions of the ratings of
fixed-income securities are contained in Appendix B to this Prospectus.     
   
  The Aggregate Bond Index Series may also invest in other instruments that
"pass through" payments on such obligations, such as collateralized mortgage
obligations ("CMOs").     
   
INTERNATIONAL INDEX FUND     
   
  The investment objective of the International Index Fund is to provide
investment results that, before expenses, seek to replicate the total return
(i.e., the combination of capital changes and income) of the Morgan Stanley
Capital International EAFE (R) GDP Weighted Index (the "EAFE Index"). There can
be no assurance that the investment objective of the Fund will be achieved.
       
  The Fund seeks to achieve its investment objective by investing all of its
assets in the Merrill Lynch International Index Series of the Trust
("International Index Series"), which has the same investment objective as the
Fund. The following is a description of the investment policies of the
International Index Series.     
   
  In seeking to replicate the total return of the EAFE Index, the Manager may
not allocate the International Index Series' investments among all of the
countries, or all of the companies within a country,     
 
                                       9
<PAGE>
 
   
represented in the EAFE Index, or in the same weightings as the EAFE Index.
Instead, the International Index Series may invest in a statistically selected
sample of the equity securities included in the EAFE Index and other types of
financial instruments. In addition, the Manager may use options and futures
contracts and other types of financial instruments relating to all or a portion
of the EAFE Index. The investments to be included in the International Index
Series will be selected so that the market capitalizations, industry weightings
and other fundamental characteristics of the stocks, and of the stocks
underlying or otherwise related to the foregoing financial instruments, closely
approximate those same factors in the EAFE Index, with the objective of
reducing the selected investment portfolio's deviation from the performance of
the EAFE Index (tracking error). The International Index Series may also engage
in securities lending and index arbitrage. See "Other Types of Investments and
Investment Techniques."     
   
  The EAFE Index is composed of equity securities of companies from various
industrial sectors whose primary trading markets are located outside the United
States and which are selected from among the larger capitalization companies in
such markets. A company's stock market capitalization is the total market value
of its outstanding shares. The countries currently included in the EAFE Index
are Australia, Austria, Belgium, Denmark, Finland, France, Germany, Hong Kong,
Ireland, Italy, Japan, Malaysia, The Netherlands, New Zealand, Norway,
Singapore, Spain, Sweden, Switzerland and United Kingdom. The weighting of the
EAFE Index among these countries is based upon gross domestic product (GDP).
(Market capitalization is the basis for country weightings in another version
of the EAFE Index. Using the GDP weighting tends to decrease the relative
weighting of Japan and the United Kingdom while increasing the weighting of
certain European countries, generally resulting in a more diversified EAFE
Index).     
 
ABOUT INDEXING AND MANAGEMENT OF THE SERIES
 
  About Indexing. The Series are not managed according to traditional methods
of "active" investment management, which involve the buying and selling of
securities based upon economic, financial, and market analyses and investment
judgment. Instead, each Series, utilizing essentially a "passive" or "indexing"
investment approach, seeks to replicate, before each Series' expenses (which
can be expected to reduce the total return of the Series), the total return of
its respective index.
   
  Indexing and Managing the Series. Under normal conditions each Series will
invest at least 80% of its assets (exclusive of assets held as collateral for
securities loans or as margin for futures transactions) in securities or other
financial instruments which are contained in, or related to the securities
contained in, the applicable index (equity securities, in the case of the S&P
500 Index Series, Small Cap Index Series and International Index Series (the
"Equity Series"), and fixed-income securities in the case of the Aggregate Bond
Index Series (the "Fixed-Income Series")).     
 
  Because each Series seeks to replicate the total return of its respective
index, generally the Manager will not attempt to judge the merits of any
particular security as an investment but will seek only to replicate the total
return of the securities in the relevant index. However, the Manager may omit
or remove a security which is included in an index from the portfolio of a
Series if, following objective criteria, the Manager judges the security to be
insufficiently liquid or believes the merit of the investment has been
substantially impaired by extraordinary events or financial conditions.
   
  In managing the Equity Series, the Manager may employ index arbitrage. Index
arbitrage involves the sale of a replicating selection, or "basket," of stocks
with the simultaneous purchase of an equivalent dollar     
 
                                       10
<PAGE>
 
value of related futures contracts, or alternatively the purchase of such an
equity basket with a simultaneous sale of related futures contracts. This
technique is designed to take advantage of a possible mispricing which could
arise between the securities market and the futures market. Extensive use of
this technique could, however, be limited by applicable tax laws.
 
  In addition, the Manager may acquire certain financial instruments based upon
individual securities or based upon or consisting of one or more baskets of
securities (which basket may be based upon a target index). Certain of these
instruments may represent an indirect ownership interest in such securities or
baskets. Others may provide for the payment to a Series or by a Series of
amounts based upon the performance (positive, negative or both) of a particular
security or basket. The Manager will select such instruments when it believes
that the use of the instrument will correlate substantially with the expected
total return of a target security or index. In connection with the use of such
instruments, the Manager may enter into short sales in an effort to adjust the
weightings of particular securities represented in the basket to more
accurately reflect such securities' weightings in the target index.
 
  Each Series' ability to replicate the total return of its respective index
may be affected by, among other things, transaction costs, administration and
other expenses incurred by the Series, taxes (including foreign withholding
taxes, which will affect the International Index Series and the Aggregate Bond
Index Series due to foreign tax withholding practices), changes in either the
composition of the index or the assets of a Series, and the timing and amount
of Series investor contributions and withdrawals, if any. In addition, each
Fund's total return will be affected by incremental operating costs (e.g.,
transfer agency, accounting) that will be borne by the Fund. Under normal
circumstances, it is anticipated that each Series' total return over periods of
one year and longer will, on a gross basis and before taking into account
expenses, be within 5 basis points (a basis point is one one-hundredth of one
percent (0.01%)) for the S&P 500 Index Fund, 100 basis points for the Small Cap
Index Fund, 150 basis points for the International Index Fund, and 25 basis
points for the Aggregate Bond Index Fund, of the total return of the applicable
indices. There can be no assurance, however, that these levels of correlation
will be achieved. In the event that this correlation is not achieved over time,
the Trustees of the Trust and the Directors of the Corporation will consider
alternative strategies for the Series and the Funds.
 
OTHER TYPES OF INVESTMENTS AND INVESTMENT TECHNIQUES OF THE SERIES
 
  Cash Management. Generally, the Manager will employ futures and options on
futures to provide liquidity necessary to meet anticipated redemptions or for
day-to-day operating purposes. However, if considered appropriate in the
opinion of the Manager, a portion of a Series' assets may be invested in
certain types of instruments with remaining maturities of 397 days or less for
liquidity purposes. Such instruments would consist of: (i) obligations of the
U.S. Government, its agencies, instrumentalities, authorities or political
subdivisions ("U.S. Government Securities"); (ii) other fixed-income securities
rated Aa or higher by Moody's or AA or higher by S&P or, if unrated, of
comparable quality in the opinion of the Manager; (iii) commercial paper; (iv)
bank obligations, including negotiable certificates of deposit, time deposits
and bankers' acceptances; and (v) repurchase agreements. At the time the Series
invests in commercial paper, bank obligations or repurchase agreements, the
issuer or the issuer's parent must have outstanding debt rated Aa or higher by
Moody's or AA or higher by S&P or outstanding commercial paper, bank
obligations or other short-term obligations rated Prime-1 by Moody's or A-1 by
S&P; or, if no such ratings are available, the instrument must be of comparable
quality in the opinion of the Manager.
 
                                       11
<PAGE>
 
   
  Portfolio Strategies Involving Futures, Options, Swaps and Indexed
Instruments. Each Series will also utilize options, futures, options on
futures, swaps and other indexed instruments. Futures and options on futures
may be employed to provide liquidity as described in the preceding paragraph,
and may also be employed in connection with a Series' index arbitrage
strategies. Futures, options on futures, swaps and other indexed instruments
may be employed as a proxy for a direct investment in securities underlying the
Series' index. In addition, the International Index Series may engage in
futures contracts on foreign currencies in connection with certain foreign
securities transactions.     
 
  The Manager will choose among the foregoing instruments based on its judgment
of how best to meet each Series' goals. In connection therewith, the Manager
will assess such factors as current and anticipated securities prices, relative
liquidity and price levels in the options, futures and swap markets compared to
the securities markets, and the Series' cash flow and cash management needs.
 
  The Series' use of the foregoing instruments and the associated risks are
described in detail in Appendix A to this Prospectus.
   
  Foreign Exchange Transactions. The International Index Series may engage in
futures contracts on foreign currencies and foreign currency forward and spot
transactions in connection with transactions or anticipated transactions in
securities denominated in foreign currencies. Specifically, the Series may
purchase or sell a currency to settle a security transaction or sell a currency
in which the Series has received or anticipates receiving a dividend or
distribution.     
 
OTHER INVESTMENT POLICIES AND PRACTICES OF THE SERIES
   
  Illiquid Investments. Each of the Series may invest up to 15% of its net
assets in illiquid investments. Pursuant to that restriction each Series may
not invest in instruments which cannot be readily resold because of legal or
contractual restrictions, which cannot otherwise be marketed, redeemed, put to
the issuer or a third party, which do not mature within seven days, or which
the Trustees have not determined to be liquid, if, regarding all such
instruments, more than 15% of its net assets, taken at market value, would be
invested in such instruments.     
   
  Each Series may purchase, without regard to the above limitation, securities
that are not registered under the Securities Act of 1933 (the "Securities Act")
but that can be offered and sold to "qualified institutional buyers" under Rule
144A under the Securities Act, provided that the Trustees, or the Manager
pursuant to guidelines adopted by the Trustees, continuously determines, based
on the trading markets for the specific Rule 144A security, that it is liquid.
The Trustees, however, will retain oversight and are ultimately responsible for
these determinations. The Trustees monitor each Series' investments in these
securities, focusing on such factors, among others, as valuation, liquidity and
availability of information. This investment practice could have the effect of
increasing the level of illiquidity in each Series to the extent that qualified
institutional buyers become for a time uninterested in purchasing these
securities.     
 
  Repurchase Agreements. Each Series may invest in securities pursuant to
repurchase agreements. Repurchase agreements may be entered into only with a
member bank of the Federal Reserve System, primary dealers in U.S. Government
securities, or an affiliate thereof, or with other entities which the Manager
otherwise deems to be creditworthy. Under repurchase agreements, the
counterparty agrees, upon
 
                                       12
<PAGE>
 
entering into the contract, to repurchase the security from the Series at a
mutually agreed upon time and price in a specified currency, thereby
determining the yield during the term of the agreement. This results in a fixed
rate of return insulated from market fluctuations during such period although
it may be affected by currency fluctuations. In the event of default by the
seller under a repurchase agreement the Series may suffer time delays and incur
costs or possible losses in connection with disposition of the collateral.
Repurchase agreements maturing in more than seven days are deemed illiquid by
the Securities and Exchange Commission and are therefore subject to the Series'
investment restrictions limiting investments in securities that are not readily
marketable to 15% of the Series' net assets.
 
  Lending of Portfolio Securities. To the extent permitted by law, each Series
may from time to time lend securities from its portfolio to banks, brokers and
other financial institutions and receive collateral in cash or securities
issued or guaranteed by the United States government. Such collateral will be
maintained at all times in an amount equal to at least 100% of the current
market value of the loaned securities. Each Series' policy concerning lending
is fundamental and it may not be changed without the approval of the holders of
a majority of the Series' outstanding voting securities, as defined in the
Investment Company Act. During the period of such a loan, the Series receives
the income on the loaned securities and either receives the income on the
collateral or other compensation, i.e., negotiated loan premium or fee, for
entering into the loan and thereby increases its yield. In the event that the
borrower defaults on its obligation to return borrowed securities, because of
insolvency or otherwise, the Series could experience delays and costs in
gaining access to the collateral and could suffer a loss to the extent that the
value of the collateral falls below the market value of the borrowed
securities. Presently, no Series intends to lend portfolio securities
representing in excess of 33 1/3% of its total assets.
   
  When-Issued Securities and Delayed Delivery Transactions. The Aggregate Bond
Index Series may purchase securities on a when-issued basis, and it may
purchase or sell securities for delayed delivery. These transactions occur when
securities are purchased or sold by the Series with payment and delivery taking
place in the future to secure what is considered an advantageous yield and
price to the Series at the time of entering into the transaction. Although the
Aggregate Bond Index Series has not established any limit on the percentage of
its assets that may be committed in connection with such transactions, the
Aggregate Bond Index Series will maintain a segregated account with its
custodian of liquid securities in an aggregate amount equal to the amount of
its commitment in connection with such purchase transactions.     
   
  Dollar Rolls. The Aggregate Bond Index Series may enter into dollar rolls, in
which the Aggregate Bond Index Series will sell securities for delivery in the
current month and simultaneously contract to repurchase substantially similar
(the same type and coupon) securities on a specified future date from the same
party. During the roll period, the Series forgoes principal and interest paid
on the securities sold. The Aggregate Bond Index Series is compensated by the
difference between the current sales price and the forward price for the future
purchase (often referred to as the "drop") as well as by the interest earned on
the cash proceeds of the initial sale.     
   
  Dollar rolls involve the risk that the market value of the securities subject
to the Aggregate Bond Index Series' forward purchase commitment may decline
below the price of the securities the Aggregate Bond Index Series has sold. In
the event the buyer of the securities files for bankruptcy or becomes
insolvent, the Aggregate Bond Index Series' use of the proceeds of the current
sale portion of the transaction may be     
 
                                       13
<PAGE>
 
   
restricted pending a determination by the other party, or its trustee or
receiver, whether to enforce the Aggregate Bond Index Series' obligation to
purchase the similar securities in the forward transaction. Dollar rolls are
speculative techniques which can be deemed to involve leverage. The Aggregate
Bond Index Series will establish a segregated account with its custodian in
which it will maintain liquid securities in an aggregate amount equal to the
amount of the forward commitment. The Aggregate Bond Index Series will engage
in dollar roll transactions to enhance return and not for the purpose of
borrowing. Each dollar roll transaction is accounted for as a sale of a
portfolio security and a subsequent purchase of a substantially similar
security in the forward market.     
   
  Standby Commitment Agreements. The Aggregate Bond Index Series may from time
to time enter into standby commitment agreements. Such agreements commit the
Aggregate Bond Index Series, for a stated period of time, to purchase a stated
amount of a fixed income security which may be issued and sold to the Series at
the option of the issuer. The price and coupon of the security is fixed at the
time of the commitment. At the time of entering into the agreement, the
Aggregate Bond Index Series is paid a commitment fee, regardless of whether or
not the security is ultimately issued. The Aggregate Bond Index Series will
enter into such agreements only for the purpose of investing in the security
underlying the commitment at a yield and price which is considered advantageous
to the Series. The Aggregate Bond Index Series will not enter into a standby
commitment with a remaining term in excess of 90 days and will limit its
investment in such commitments so that the aggregate purchase price of the
securities subject to such commitments, together with the value of all other
illiquid securities, will not exceed 15% of its total assets taken at the time
of acquisition of such commitment or security. The Aggregate Bond Index Series
will at all times maintain a segregated account with its custodian of liquid
securities in an aggregate amount equal to the purchase price of the securities
underlying the commitment.     
   
  There can be no assurance that the securities subject to a standby commitment
will be issued and the value of the security, if issued, on the delivery date
may be more or less than its purchase price. Because the issuance of the
security underlying the commitment is at the option of the issuer, the
Aggregate Bond Index Series may bear the risk of a decline in the value of such
security and may not benefit from an appreciation in the value of the security
during the commitment period.     
   
  The purchase of a security subject to a standby commitment agreement and the
related commitment fee will be recorded on the date on which the security can
reasonably be expected to be issued, and the value of the security will
thereafter be reflected in the calculation of the Aggregate Bond Index Series'
net asset value. The cost basis of the security will be adjusted by the amount
of the commitment fee. In the event the security is not issued, the commitment
fee will be recorded as income on the expiration date of the standby
commitment.     
 
  Short Sales. In connection with the use of certain instruments based upon or
consisting of one or more baskets of securities, the Manager may sell a
security a Series does not own, or in an amount greater than the Series owns
(i.e., make short sales). Such transactions will be used only in an effort to
adjust the weightings of particular securities represented in the basket to
reflect such securities' weightings in the target index. The Manager will not
employ short sales in reflection of the Manager's outlook for the securities
markets or for the performance of the securities sold short. Generally, to
complete a short sale transaction, the Series will borrow the security to make
delivery to the buyer. The Series is then obligated to replace the security
borrowed. The price at the time of replacement may be more or less than the
price at which the security was
 
                                       14
<PAGE>
 
sold by the Series. Until the security is replaced, the Series is required to
pay to the lender any interest which accrues during the period of the loan. To
borrow the security, the Series may be required to pay a premium which would
increase the cost of the security sold. The proceeds of the short sale will be
retained by the broker to the extent necessary to meet margin requirements
until the short position is closed out. Until the Series replaces the borrowed
security, it will (a) maintain in a segregated account with its custodian cash
or liquid securities at such a level that the amount deposited in the account
plus the amount deposited with the broker as collateral will equal the current
market value of the security sold short or (b) otherwise cover its short
position.
 
INVESTMENT RESTRICTIONS
 
  The Funds' and the Series' investment activities are subject to further
restrictions that are described in the Statement of Additional Information.
Investment restrictions and policies which are fundamental policies may not be
changed without the approval of the holders of a majority of the Funds' or
Series' outstanding voting securities as defined in the Investment Company Act.
   
  Among the more significant fundamental restrictions, a Series or Fund may not
invest more than 25% of its total assets (taken at market value at the time of
each investment) in the securities of issuers in any particular industry
(excluding the U.S. Government and its agencies and instrumentalities);
provided, that in replicating the weighting of a particular industry in its
target index, a Series or Fund may invest more than 25% of its total assets in
securities of issuers in that industry. In addition, although each Fund is
classified as a non-diversified fund under the Investment Company Act and is
not subject to the diversification requirements of the Investment Company Act,
each Fund is required to comply with certain requirements under the Internal
Revenue Code of 1986, as amended (the "Code"). To ensure that the Funds satisfy
these requirements, the Declaration of Trust requires that each Series be
managed in compliance with the Code requirements as though such requirements
were applicable to the Series. These requirements include limiting its
investments so that at the close of each quarter of the taxable year (i) not
more than 25% of the market value of a Fund's total assets are invested in the
securities of a single issuer, or any two or more issuers which are controlled
by the Fund and engaged in the same, similar or related businesses, and (ii)
with respect to 50% of the market value of its total assets, not more than 5%
of the market value of its total assets are invested in the securities of a
single issuer, and the Fund does not own more than 10% of the outstanding
voting securities of a single issuer. The U.S. Government, its agencies and
instrumentalities are not included within the definition of "issuer" for
purposes of the diversification requirements of the Code. These requirements
will be satisfied at the Series level and not at the level of the Funds based
upon a ruling received from the Internal Revenue Service ("IRS") which entitles
the Funds to "look through" the shares of the Series to the underlying
investments of the Series for purposes of these diversification requirements.
    
  The Funds' and Series' investment objectives are not fundamental policies,
and may be changed by the Directors and the Trustees, respectively, without
shareholder approval. THE TRUSTEES AND THE DIRECTORS MAY ALSO CHANGE THE TARGET
INDEX OF ANY RESPECTIVE SERIES AND FUND IF THEY CONSIDER THAT A DIFFERENT INDEX
WOULD FACILITATE THE MANAGEMENT OF THE SERIES AND FUND IN A MANNER WHICH BETTER
ENABLES THE FUND AND SERIES TO SEEK TO REPLICATE THE TOTAL RETURN OF THE MARKET
SEGMENT REPRESENTED BY THE CURRENT INDEX.
 
RISK FACTORS
 
  Each Fund will be subject to the risks associated with an investment in its
corresponding Series. These risks are set forth below.
 
                                       15
<PAGE>
 
  Cash Flows; Expenses. The ability of each Series to satisfy its investment
objective depends to some extent on the Manager's ability to manage cash flow
(primarily from purchases and redemptions and distributions from the Series'
investments). The Manager will make investment changes to a Series' portfolio
to accommodate cash flow while continuing to seek to replicate the total return
of the Series' target index. Investors should also be aware that the investment
performance of each index is a hypothetical number which does not take into
account brokerage commissions and other transaction costs, custody and other
costs of investing, which will be borne by the Series, and any incremental
operating costs (e.g., transfer agency, accounting) that will be borne by the
Funds. Finally, since each Series seeks to replicate the total return of its
target index, the Manager generally will not attempt to judge the merits of any
particular security as an investment.
   
  Options, Futures, Swaps and Indexed Instruments. The Manager expects to use
options, futures, options on futures, swaps and indexed instruments as
described above under "About Indexing and Management of the Series--Other Types
of Investments and Techniques--Portfolio Strategies Involving Futures, Options,
Swaps and Indexed Instruments." Use of such instruments may involve investment
risks and transaction costs to which the Series would not be subject absent the
use of these instruments. A discussion of these instruments is contained in
Appendix A to this Prospectus.     
 
  Investment in Foreign Securities. Investments on an international basis
involve certain risks not typically involved in domestic investments, including
fluctuations in foreign exchange rates, future political and economic
developments, and the possible imposition of exchange controls or other foreign
or U.S. governmental laws or restrictions applicable to such investments.
Securities prices in different countries are subject to different economic,
financial, political and social factors. Moreover, individual foreign economies
may differ favorably or unfavorably from the United States economy in such
respects as growth of gross domestic product, rate of inflation, capital
reinvestment, resources, self-sufficiency and balance of payments position.
Also, it is anticipated that most of the foreign securities held by a Series
will not be registered with the Securities and Exchange Commission nor will the
issuers thereof be subject to the reporting requirements of such agency. In
addition, foreign investors such as the Series may be subject to withholding
taxes in certain countries, which may reduce the returns of the Series.
   
  Since the International Index Series will invest heavily in securities
denominated or quoted in currencies other than the United States dollar,
changes in foreign currency exchange rates will affect the value of securities
in the Series' portfolio and the unrealized appreciation or depreciation of
investments so far as United States investors are concerned. Currencies of
certain foreign countries may be volatile and therefore may affect the value of
securities denominated in such currencies. Changes in foreign currency exchange
rates relative to the United States dollar will affect the United States dollar
value of the Series' assets denominated in that currency and the return on such
assets. The rate of exchange between the dollar and other currencies is
determined by forces of supply and demand in the foreign exchange markets.
These forces are, in turn, affected by the international balance of payments,
the level of interest and inflation rates and other economic and financial
conditions, government intervention, speculation and other factors.     
   
  Investment in Fixed-Income Securities. Because the Aggregate Bond Index
Series will invest in fixed-income securities, it will be subject to the
general risks inherent is such securities, primarily interest rate risk, credit
risk and prepayment risk.

  Interest rate risk is the potential for fluctuations in bond prices due to
changing interest rates. As a rule bond prices vary inversely with interest
rates. If interest rates rise, bond prices generally decline; if interest rates
fall, bond prices generally rise. In addition, for a given change in interest
rates, longer-maturity bonds generally fluctuate more in price than shorter-
maturity bonds. To compensate investors for these larger fluctuations, longer-
maturity bonds usually offer higher yields than shorter-maturity bonds, other
factors, including credit quality, being equal. These basic principles of bond
prices also apply to U.S. Government Securities. A security backed by the "full
faith and credit" of the U.S. Government is guaranteed only as to its stated
interest rate and face value at maturity, not its current market price. Just
like other fixed-income securities, government-guaranteed securities will
fluctuate in value when interest rates change.
   
  Credit risk is the possibility that an issuer of securities held by the
Aggregate Bond Index Series will be unable to make payments of either interest
or principal or will be perceived to have a diminished capacity to make such
payments in the future. The credit risk of the Aggregate Bond Index Series is a
function of the diversification and credit quality of its underlying
securities.     
   
  The Aggregate Bond Index Series may also be exposed to event risk, which
includes the possibility that fixed-income securities held by the Aggregate
Bond Index Series may suffer a substantial decline in credit quality and market
value due to issuer restructurings. Certain restructurings such as mergers,
leveraged buyouts, takeovers or similar events, are often financed by a
significant expansion of corporate debt. As a result of the added debt burden,
the credit quality and market value of a firm's existing debt securities may
decline significantly. Other types of restructurings (such as corporate
spinoffs or privatizations of governmental or agency borrowers or the
termination of express or implied governmental credit support) may also result
in decreased credit quality of a particular issuer.     
   
  Prepayment risk is the possibility that the principal of the mortgage loans
underlying mortgage-backed securities may be prepaid at any time. As a general
rule, prepayments increase during a period of falling interest rates and
decrease during a period of rising interest rates. As a result of prepayments,
in periods of declining interest rates the Aggregate Bond Index Series may be
required to reinvest its assets in securities with lower interest rates. In
periods of increasing interest rates, prepayments generally may decline, with
the effect that the mortgage-backed securities held by the Aggregate Bond Index
Series may exhibit price characteristics of longer-term debt securities.     
   
  The corporate substitution strategy used by the Aggregate Bond Index Series
(discussed above) may increase or decrease the Aggregate Bond Index Series'
exposure to the foregoing risks relative to those of the Aggregate Bond Index.
       
  Investments in Small Companies. The Small Cap Index Series will invest
primarily in securities of smaller capitalization issuers. Investments in
securities of smaller capitalization issuers involve special considerations and
risks not typically associated with investments in securities of larger
capitalization issuers, including an issuer's limited product lines, markets or
financial resources, or dependence on a limited management group. In addition,
many smaller capitalization stocks trade less frequently and in smaller volume,
and may be subject to more abrupt or erratic price movements, than stocks of
larger companies. The securities of smaller companies may also be more
sensitive to market changes than the securities of larger companies.     
   
  Portfolio Turnover. Although each Series will use a passive, indexing
approach to investing, each Series may engage in a substantial number of
portfolio transactions. The rate of portfolio turnover will be a limiting     
 
                                       17
<PAGE>
 
factor when the Manager considers whether to purchase or sell securities for a
Series only to the extent that the Manager will consider the impact of
transaction costs on a Series' tracking error. Changes in the securities
comprising a Series' index will tend to increase that Series' portfolio
turnover rate, as the Manager restructures the Series' holdings to reflect the
changes in the index. The portfolio turnover rate is, in summary, the
percentage computed by dividing the lesser of a Series' purchases or sales of
securities by the average net asset value of the Series. High portfolio
turnover involves correspondingly greater brokerage commissions for a Series
investing in equity securities and other transaction costs which are borne
directly by a Series. A high portfolio turnover rate may also result in the
realization of taxable capital gains, including short-term capital gains
taxable at ordinary income rates.
   
  While it is impossible to predict the portfolio turnover rates for each of
the Series, it is anticipated that the portfolio turnover rates for each of the
Series will not exceed 100%. For the period April 3, 1997 (commencement of
operations) to June 30, 1997, the portfolio turnover of the S&P 500 Index
Series and the Aggregate Bond Index Series was 1.39% and 62.75%, respectively.
For the period April 9, 1997 (commencement of operations) to June 30, 1997, the
portfolio turnover of the Small Cap Index Series and the International Index
Series was 26.02% and 5.45%, respectively.

Directors have adopted procedures that they believe are reasonably designed to
resolve any conflicts that arise in connection with this overlap.
 
ADMINISTRATION OF THE CORPORATION AND THE FUNDS
 
  The Corporation does not have an investment adviser, since all of each Fund's
assets will be invested in its corresponding Series. The Corporation has
retained the services of MLAM as administrator of the Funds (the
"Administrator"). Under the Administration Agreement, the Administrator
provides the Funds with administrative services.
 
                                       20

ADVISORY ARRANGEMENTS OF THE TRUST AND THE SERIES
 
  MLAM, with offices at 800 Scudders Mill Road, Plainsboro, New Jersey (mailing
address: Box 9011, Princeton, New Jersey 08543-9011) also acts as manager for
the Trust and each Series and provides them with management and investment
advisory services.
   
  MLAM is owned and controlled by Merrill Lynch & Co., Inc. ("ML & Co."), a
financial services holding company and the parent of Merrill Lynch. MLAM or its
affiliate, FAM, acts as the manager and investment adviser for more than 140
other registered investment companies. MLAM also offers portfolio management
and portfolio analysis services to individuals and institutions. As of July 31,
1997, MLAM and FAM had a total of approximately $267.2 billion in investment
company and other portfolio assets under management, including accounts of
certain affiliates of MLAM.     
   
  Eric Mitofsky is primarily responsible for the day-to-day management of the
investments of the S&P 500 Index Series, Small Cap Index Series and
International Index Series. Mr. Mitofsky has been associated with MLAM since
1992, and has been a Vice President of MLAM since 1992. Jay C. Harbeck and
Gregory M. Maunz are primarily responsible for the day-to-day management of the
investments of the Aggregate Bond Index Series. Mr. Harbeck has been a Vice
President of MLAM since 1986, and Mr. Maunz has been a Vice President of MLAM
since 1985.

  The Funds pay the Administrator monthly compensation at the annual rates of
the average daily net assets of each Fund as follows:
 
<TABLE>

   International Index Fund.................................       0.24%
</TABLE>    
   
  In addition, the administration agreement with the Administrator (the
"Administration Agreement") obligates the Corporation to pay certain expenses
incurred in its operations including, among other things, legal and audit fees,
registration fees, unaffiliated Directors' fees and expenses, custodian and
transfer agency fees, accounting costs, the costs of issuing and redeeming
shares and certain of the costs of printing proxies, shareholder reports,
prospectuses and statements of additional information. For the period April 3,
1997 (commencement of operations) to June 30, 1997, the total fee paid by the
S&P 500 Index Fund and the Aggregate Bond Index Fund to the Administrator was
$94,046 and $28,078, respectively. For the period April 9, 1997 (commencement
of operations) to June 30, 1997, the total fee paid by the Small Cap Index Fund
and the International Index Fund to the Administrator was $16,520, and $50,554,
respectively. Accounting services are provided to each Fund by the
Administrator, and each Fund reimburses the Administrator for its costs in
connection with such services on a semi-annual basis. For the period April 3,
1997 (commencement of operations) to June 30, 1997, the amount of such
reimbursement for the S&P 500 Index Fund and the Aggregate Bond Index Fund was
$47,980 and $58,786, respectively. For the period April 9, 1997 (commencement
of operations) to June 30, 1997, the amount of such reimbursement for the Small
Cap Index Fund and the International Index Fund was $41,132 and $23,561,

  In addition, the management agreement with the Manager (the "Management
Agreement") obligates the Trust to pay certain expenses incurred in its
operations including, among other things, legal and audit fees, registration
fees, unaffiliated trustees' fees and expenses, custodian and transfer agency
fees, accounting costs, the costs of issuing and redeeming shares and certain
of the costs of printing proxies, shareholder reports, prospectuses and
statements of additional information. For the period April 3, 1997
(commencement of operations) to June 30, 1997, the fee earned by the Manager,
from the S&P 500 Index Series and the Aggregate Bond Index Series was $23,504
and $12,712, respectively (based on average daily net assets of approximately
$195.0 million and $83.2 million, respectively), all of which was voluntarily
waived. For the period April 9, 1997 (commencement of operations) to June 30,
1997, the fee earned by the Manager, from the Small Cap Index Series, and the
International Index Series was $6,005, and $23,163, respectively (based on
average daily net assets of approximately $33.4 million, and $93.8 million,
respectively), all of which was voluntarily waived. Shareholders bear the
expenses of a Fund directly and the expenses of the Series in which the Fund
has invested, indirectly. For the period April 3, 1997 (commencement of
operations) to June 30, 1997, the ratio of total expenses to average net assets
was .54% and .84% for Class A shares and Class D shares of S&P 500 Index Fund,
 .70% and 1.05% for Class A shares and Class D shares of Aggregate Bond Index
Fund, .14% for the S&P 500 Index Series and .27% for the Aggregate Bond Index
Series. For the period April 9, 1997 (commencement of operations) to June 30,
1997, the ratio of total expenses to average net assets was 1.20% and 1.46% for
Class A shares and Class D shares of Small Cap Index Fund, .87% and 1.14% for
Class A shares and Class D shares of International Index Fund, .37% for the
Small Cap Index Series and .32% for the International Index Series. Accounting
services are provided to the Trust by the Manager, and each Fund and Series
reimburses the Manager for its costs in connection with such services on a
semi-annual basis. For the period April 3, 1997 (commencement of operations) to
June 30, 1997, the amount of such reimbursement for the S&P 500 Index Fund,
Aggregate Bond Index Fund, S&P 500 Index Series and Aggregate Bond Index Series
was $1,302, $1,591, $10,574 and $8,519, respectively. For the period April 9,
1997 (commencement of operations) to June 30, 1997, the amount of such
reimbursement for the Small Cap Index Fund, the International Index Fund, Small
Cap Index Series and the International Index Series was $1,496, $1,597, $3,259
and $10,781, respectively.     
 
  The Directors of the Corporation believe that the aggregate per share
expenses of each Fund and corresponding Series should not be significantly
greater than the expenses which each Fund would incur if it retained the
services of an investment adviser and the assets of each Fund were invested
directly in the type of securities held by the corresponding Series.
 
TRANSFER AGENCY SERVICES
   
  MLFDS, which is a subsidiary of ML & Co., acts as the Corporation's Transfer
Agent pursuant to a Transfer Agency, Dividend Disbursing Agency and Shareholder
Servicing Agency Agreement (the "Transfer Agency Agreement"). Pursuant to the
Transfer Agency Agreement, the Transfer Agent is responsible for the issuance,
transfer and redemption of shares and the opening and maintenance of
shareholder accounts.     
 
                                       22
<PAGE>
 
   
Pursuant to the Transfer Agency Agreement, the Transfer Agent receives an
annual fee at the annual rate of .05% of the average daily value of the net
assets of a Fund for its services and is entitled to reimbursement for certain
transaction charges and out-of-pocket expenses incurred by the Transfer Agent
under the Transfer Agency Agreement. For purposes of the Transfer Agency
Agreement, the term "account" includes a shareholder account maintained
directly by the Transfer Agent and any other account representing the
beneficial interest of a person in the relevant share class on a recordkeeping
system, provided the recordkeeping system is maintained by a subsidiary of ML &
Co. For the period April 3, 1997 (commencement of operations) to June 30, 1997,
the total fee paid by the S&P 500 Index Fund and the Aggregate Bond Index Fund
was $24,456 and $8,469, respectively. For the period April 9, 1997
(commencement of operations) to June 30, 1997, the total fee paid by the Small
Cap Index Fund, and the International Index Fund to the Transfer Agent was
$3,750, and $10,532, respectively. MLFDS also acts as the transfer agent to the
Trust.     
 
CODES OF ETHICS
 
  The Board of Directors of the Corporation has adopted a Code of Ethics
pursuant to Rule 17j-1 under the Investment Company Act which incorporates the
Codes of Ethics of the Trust and of MLAM (together, the "Ethics Codes"). The
Ethics Codes significantly restrict the personal investing activities of all
employees of the Manager and, as described below, impose additional, more
onerous, restrictions on fund investment personnel.
 
  The Ethics Codes require that all employees of the Manager preclear any
personal securities investment (with limited exceptions, such as government
securities). The preclearance requirement and associated procedures are
designed to identify any substantive prohibition or limitation applicable to
the proposed investment. The substantive restrictions applicable to all
employees of the Manager include a ban on acquiring any securities in a "hot"
initial public offering and a prohibition from profiting on short-term trading
in securities. In addition, no employee may purchase or sell any security which
at the time is being purchased or sold (as the case may be), or to the
knowledge of the employee is being considered for purchase or sale, by any fund
advised by the Manager. Furthermore, the Ethics Codes provide for trading
"blackout periods" which prohibit trading by investment personnel of the Trust
within periods of trading by the Series in the same (or equivalent) security
(15 or 30 days depending upon the transaction).
 
                               PURCHASE OF SHARES
 
  Merrill Lynch Funds Distributor, Inc. (the "Distributor"), an affiliate of
both MLAM and Merrill Lynch, acts as the distributor of the shares of the Fund.
 
  The Fund offers two classes of shares, Class A shares and Class D shares.
Class A shares of the Fund are offered at a price equal to the next determined
net asset value per share without the imposition of any front-end or deferred
sales charge, and are not subject to any ongoing account maintenance or
distribution fee. Distribution of Class A shares of the Fund is limited to
certain eligible investors. Class D shares of each Fund are offered at a price
equal to the next determined net asset value per share without the imposition
of any front-end or deferred sales charge and are not subject to any ongoing
distribution fee, but are subject to an ongoing account maintenance fee at an
annual rate of 0.25% of average daily net assets.
 
  Class A shares are offered to a limited group of investors who participate in
certain investment programs which charge a fee for participation, including the
Merrill Lynch Mutual Fund Adviser program. In addition,
 
                                       23
<PAGE>
 
   
Class A shares are offered to ML & Co. and its subsidiaries and their directors
and employees and to members of the Boards of MLAM-advised investment
companies, including the Corporation. For more information about these
programs, contact the Transfer Agent at 1-800-MER-FUND.     
   
  Shares of the Corporation may be purchased from securities dealers or by
mailing a purchase order directly to the Transfer Agent. Shareholders may
redeem their shares at any time at the next determined net asset value. The
minimum initial purchase is $1,000 and the minimum subsequent purchase is $50,
except that for retirement plans the minimum initial investment is $100 and the
minimum subsequent purchase is $1. Merrill Lynch may charge its customers a
processing fee (currently $5.35) for confirming purchases and repurchases.
Purchase and redemptions directly through the Corporation's transfer agent are
not subject to processing fees.     
 
  The Distributor also acts as the placement agent for the Trust.
 
ACCOUNT MAINTENANCE PLAN
   
  Pursuant to a plan adopted by the Corporation with respect to the Class D
shares of each Fund pursuant to Rule 12b-1 under the Investment Company Act
(the "Plan"), the Class D shares of each Series pay the Distributor an ongoing
account maintenance fee, accrued daily and paid monthly, at the annual rate of
0.25% of the average daily net assets attributable to such shares. Pursuant to
a sub-agreement with the Distributor, Merrill Lynch also provides account
maintenance services in respect of the Class D shares of each Fund. The ongoing
account maintenance fee compensates the Distributor and Merrill Lynch for
providing account maintenance services to Class D shareholders. For the period
April 3, 1997 (commencement of operations) to June 30, 1997, the S&P 500 Index
Fund and the Aggregate Bond Index Fund paid the Distributor $30,273 and
$15,931, respectively, pursuant to the Plan (based on average daily net assets,
subject to such Class D Plan of approximately $50.2 million and $26.4 million,
respectively), all of which was paid to Merrill Lynch for providing account
maintenance activities in connection with Class D shares. For the period April
9, 1997 (commencement of operations) to June 30, 1997, the Small Cap Index Fund
and the International Index Fund paid the Distributor $10,709, and $14,371,
respectively, pursuant to the Plan (based on average daily net assets, subject
to such Class D Plan of approximately $19.1 million, and $25.6 million,
respectively), all of which was paid to Merrill Lynch for providing account
maintenance activities in connection with Class D Shares.     
 
                              REDEMPTION OF SHARES
 
  Each Fund is required to redeem all full and fractional shares of the Fund
upon receipt of a written request in proper form. The redemption price is the
net asset value per share next determined after the initial receipt of proper
notice of redemption. There will be no additional charge for redemption if the
redemption request is sent directly to the Transfer Agent. Shareholders
liquidating their holdings will receive upon redemption all dividends
reinvested through the date of redemption. The value of shares at the time of
redemption may be more or less than the shareholder's cost, depending on the
market value of the securities held by the Fund at such time. The Corporation
will generally pay redemptions in cash; however, if requested by a shareholder,
at the discretion of the Administrator the Corporation may pay a redemption or
repurchase of shares in an amount of $10,000,000 or more (which amount may be
decreased or increased by the Administrator from time to time) with portfolio
securities.

REDEMPTION
 
  A shareholder wishing to redeem shares may do so without charge by tendering
the shares directly to the Transfer Agent, Merrill Lynch Financial Data
Services, Inc., P.O. Box 45289, Jacksonville, Florida 32232-5289. Redemption
requests delivered other than by mail should be delivered to Merrill Lynch
Financial Data Services, Inc., Transfer Agency Operations Department, 4800 Deer
Lake Drive East, Jacksonville, Florida 32246-6484. Redemption requests should
not be sent to the Corporation. Proper notice of redemption in the case of
shares deposited with the Transfer Agent may be accomplished by a written
letter requesting redemption. Proper notice of redemption in the case of shares
for which certificates have been issued may be accomplished by a written letter
as noted above accompanied by certificates for the shares to be redeemed. The
notice in either event requires the signatures of all persons in whose names
the shares are registered, signed exactly as their names appear on the Transfer
Agent's register or on the certificate, as the case may be. The signature(s) on
the notice must be guaranteed by an "eligible guarantor institution" as such
term is defined in Rule 17Ad-15 under the Securities Exchange Act of 1934, the
existence and validity of which may be verified by the Transfer Agent through
the use of industry publications. "Eligible guarantor institution(s)" include
certain banks, brokers, dealers, credit unions, securities exchanges and
associations, clearing agencies and savings association. Notarized signatures
are not sufficient. In certain instances, the Transfer Agent may require
additional documents, such as, but not limited to, trust instruments, death
certificates, appointments as executor or administrator, or certificates of
corporate authority. For shareholders redeeming directly with the Transfer
Agent, payment will be mailed within seven days of receipt of a proper notice
of redemption.
 
  At various times a Fund may be requested to redeem shares for which it has
not yet received good payment. The Fund may delay or cause to be delayed the
mailing of a redemption check until such time as it has assured itself that
good payment (e.g., cash or certified check drawn on a United States bank) has
been collected for the purchase of such shares. Normally, this delay will not
exceed 10 days.
 
REPURCHASE
   
  Each Fund also will repurchase shares through a shareholder's listed
securities dealer. The Funds normally will accept orders to repurchase shares
by wire or telephone from dealers for their customers at the net asset value
next computed after receipt of the order by the dealer, provided that the
request for repurchase is received by the dealer prior to the close of business
on the New York Stock Exchange ("NYSE") on the day received, and such request
is received by a Fund from such dealer not later than 30 minutes after the
close of business on the NYSE (generally 4:00 P.M., New York time), on the same
day. Dealers have the responsibility to submit such repurchase requests to the
Fund not later than 30 minutes after the close of business on the NYSE in order
to obtain that day's closing price.     
   
  The foregoing repurchase arrangements are for the convenience of shareholders
and do not involve a charge by a Fund. Securities firms which do not have
selected dealer agreements with the Distributor, however, may impose a
transaction charge on the shareholder for transmitting the notice of repurchase
to the Fund. Merrill Lynch may charge its customers a processing fee (presently
$5.35) to confirm a repurchase of shares to such customers. Repurchases
directly through the Fund's Transfer Agent are not subject to the processing
fee. The Corporation reserves the right to reject any order for repurchase,
which right of rejection might adversely affect shareholders seeking redemption
through the repurchase procedure. A shareholder whose order for repurchase is
rejected by a Fund, however, may redeem shares as set forth above.

                              SHAREHOLDER SERVICES
 
  The Corporation offers a number of shareholder services and investment plans
designed to facilitate investment in its shares. Full details as to each of
such services, copies of the various plans described below and instructions as
to how to participate in the various plans and services, or to change options
with respect thereto, can be obtained from the Corporation, the Distributor or
Merrill Lynch. Included in such services are the following:
 
INVESTMENT ACCOUNT
 
  Each shareholder whose account is maintained at the Transfer Agent has an
Investment Account and will receive statements, at least quarterly, from the
Transfer Agent. These statements will serve as transaction confirmations for
automatic investment purchases and the reinvestment of ordinary income
dividends and long-term capital gains distributions. The statement will also
show any other activity in the account since the preceding statements.
Shareholders will receive separate transaction confirmations for each purchase
or sale transaction other than automatic investment purchase and the
reinvestment of ordinary income dividends and long-term capital gains
distribution. Shareholders may make additions to their Investment Account at
any time by mailing a check directly to the Transfer Agent. Shareholders may
also maintain their accounts through Merrill Lynch. Upon the transfer of shares
out of a Merrill Lynch brokerage account, an Investment Account in the
transferring shareholder's name will be opened automatically, without charge,
at the Transfer Agent. Shareholders interested in transferring their shares
from Merrill Lynch and who do not wish to have an Investment Account maintained
for such shares at the Transfer Agent may request their new brokerage firm to
maintain such shares in an account registered in the name of the brokerage firm
for the benefit of the shareholder. If the new brokerage firm is willing to
accommodate the shareholder in this manner, the shareholder must request that
he be issued certificates for his shares, and then must turn the certificates
over to the new firm for re-registration as described in the preceding
sentence. Shareholders considering transferring from Merrill Lynch to another
brokerage firm or financial institution should be aware that, if the firm to
which the account is to be transferred will not take delivery of shares of a
Fund, a shareholder must either redeem the shares so that the cash proceeds can
be transferred to the account at the new firm, or such shareholder must
continue to maintain an account at Merrill Lynch for those shares.
 
  Share certificates are issued only for full shares and only upon the specific
request of the shareholder. Issuance of certificates representing all or only
part of the full shares in an Investment Account may be requested by a
shareholder directly from the Transfer Agent.
 
AUTOMATIC REINVESTMENT OF DIVIDENDS AND CAPITAL GAINS DISTRIBUTIONS
 
  All dividends and capital gains distributions are reinvested automatically in
full and fractional shares of the Funds at the net asset value per share next
determined on the ex-dividend date of such dividends and distributions. A
shareholder may at any time, by written notification or by telephone (1-800-
MER-FUND) or by written notification to Merrill Lynch if the shareholder's
account is maintained with Merrill Lynch, or the Transfer Agent, if the
shareholder's account is maintained with the Transfer Agent, elect to have
subsequent dividends, or both dividends and capital gains distributions, paid
in cash rather than reinvested, in which event payment will be mailed on or
about the payment date.
 
SYSTEMATIC WITHDRAWAL PLANS
 
  A shareholder may elect to receive systematic withdrawal payments from such
shareholder's Investment Account in the form of payments by check or through
automatic payment by direct deposit to such
 
                                       26
<PAGE>
 
shareholder's bank account on either a monthly or quarterly basis. Shareholders
whose shares are held within a CMA(R), CBA(R) or Retirement Account may elect
to have shares redeemed on a monthly, bi-monthly, quarterly, semiannual or
annual basis through the Systematic Redemption Program, subject to certain
conditions.
   
EXCHANGE PRIVILEGE     
   
  Shareholders of certain fee based programs and/or employer-sponsored
retirement plans are allowed to exchange the various share classes for other
classes of a second MLAM-advised mutual fund.     
 
AUTOMATIC INVESTMENT PLANS
   
  Regular additions of shares may be made in an investor's Investment Account
by prearranged charges of $50 or more to such investor's regular bank account.
Investors who maintain CMA(R) or CBA(R) accounts may arrange to have periodic
investments made in the Funds in their CMA(R) or CBA(R) account or in certain
related accounts in amounts of $100 or more through the CMA(R) or CBA(R)
Automated Investment Program.     
       
RETIREMENT PLANS
 
  Self-directed individual retirement accounts and other retirement plans are
available from Merrill Lynch. Under these plans, investments may be made in the
Funds and in certain of the other mutual funds sponsored by Merrill Lynch as
well as in other securities. Merrill Lynch charges an initial establishment fee
and an annual custodial fee for each account. In addition, eligible
shareholders of a Fund may participate in a variety of qualified employee
benefit plans which are available from the Distributor. The minimum initial
purchase to establish any such plan is $100 and the minimum subsequent purchase
is $1.
 
                                PERFORMANCE DATA
 
  From time to time a Fund may include its average annual total return and/or
yield for various specified time periods in advertisements or information
furnished to present or prospective shareholders. Average annual total return
and yield are computed in accordance with formulas specified by the Securities
and Exchange Commission.
 
  Average annual total return quotations for the specified periods will be
computed by finding the average annual compounded rates of return (based on net
investment income and any capital gains or losses on portfolio investments over
such periods) that would equate the initial amount invested to the redeemable
value of such investment at the end of each period. Average annual total return
will be computed assuming all dividends and distributions are reinvested and
taking into account all applicable recurring and nonrecurring expenses.
 
  Each Fund also may quote total return and aggregate total return performance
data for various specified time periods. Such data will be calculated
substantially as described above, except that the rates of return calculated
will not be average annual rates, but rather, actual annual, annualized or
aggregate rates of return. Aside from the impact on the performance data
calculations of including or excluding the maximum applicable sales charges,
actual annual or annualized total return generally will be lower than average
annual total return data since the average annual rates of return reflect
compounding; aggregate total return data
 
                                       27
<PAGE>
 
generally will be higher than average annual total return data since the
aggregate rates of return reflect compounding over a longer period of time. A
Fund's total return may be expressed either as a percentage or as a dollar
amount in order to illustrate the effect of such total return on a hypothetical
$1,000 investment in the Fund at the beginning of each specified period.
 
  Total return figures are based on a Fund's historical performance and are not
intended to indicate future performance. A Fund's total return will vary
depending on market conditions, the securities comprising the Fund's portfolio,
the Fund's operating expenses and the amount of realized and unrealized net
capital gains or losses during the period. The value of an investment in a Fund
will fluctuate and an investor's shares, when redeemed, may be worth more or
less than their original cost.
 
  Yield quotations will be computed based on a 30-day period by dividing (a)
the net income based on the yield of each security earned during the period by
(b) the average number of shares outstanding during the period that were
entitled to receive dividends multiplied by the maximum offering price per
share on the last day of the period.
 
  Each Fund will generally compare its performance to the index it attempts to
replicate. A Fund may also compare its performance to data contained in
publications such as Lipper Analytical Services, Inc., or performance data
published by Morningstar Publications, Inc., Money Magazine, U.S. News and
World Report, Business Week, CDA Investment Technology, Inc., Forbes Magazine
and Fortune Magazine. From time to time, a Fund may include the Fund's
Morningstar risk-adjusted performance ratings in advertisements or supplemental
sales literature. As with other performance data, performance comparisons
should not be considered representative of a Fund's relative performance for
any future period.
 
  The Funds' annual report will contain additional performance information and
will be available upon request and without charge.
 
                                     TAXES
   
  The Funds and Their Shareholders. Each Fund intends to continue to qualify
for the special tax treatment afforded regulated investment companies ("RICs")
under the Code. If it so qualifies, in any taxable year in which it distributes
(in cash or additional shares of the Fund) at least 90% of its taxable net
income, the Fund will not be subject to Federal income tax to the extent that
it distributes its net investment income and realized capital gains to its
shareholders. Each Fund intends to distribute substantially all of such income.
       
  Dividends paid by a Fund from its ordinary income and distributions of the
Fund's net realized short-term capital gains (together referred to hereafter as
"ordinary income dividends") are taxable to shareholders as ordinary income.
Distributions made from a Fund's net realized mid- or long-term capital gains
(including long-term gains from certain transactions in futures and options)
("capital gains dividends") are taxable to shareholders as mid- or long-term
capital gains, regardless of the length of time the shareholder has owned Fund
shares. Any loss upon the sale or exchange of Fund shares held for six months
or less, however, will be treated as long-term capital loss to the extent of
any capital gains distributions received by the shareholder with respect to
such shares. Distributions in excess of a Fund's earnings and profits will
first reduce the adjusted tax basis of a holder's shares and, after such
adjusted tax basis is reduced to zero, will constitute capital gains to such
holder (assuming the shares are held as a capital asset).     
 
  Dividends are taxable to shareholders even though they are reinvested in
additional shares of a Fund. Not later than 60 days after the close of its
taxable year, the Funds will provide shareholders with a written
 
                                       28
<PAGE>
 
notice designating the amounts of any ordinary income dividends or capital
gains dividends. A portion of the ordinary income dividends paid by the S&P 500
Index Fund and the Small Cap Index Fund may be eligible for the 70% dividends
received deduction allowed to corporations under the Code, if certain
requirements are met. Distributions paid by the Aggregate Bond Index Fund and
the International Index Fund will not be eligible for the dividends received
deduction. If a Fund pays a dividend in January which was declared in the
previous October, November or December to shareholders of record on a specified
date in one of such months, then such dividend will be treated for tax purposes
as being paid by the Fund and received by its shareholders on December 31 of
the year in which such dividend was declared.
 
  Ordinary income dividends paid by a Fund to shareholders who are nonresident
aliens or foreign entities generally will be subject to a 30% United States
withholding tax under existing provisions of the Code applicable to foreign
individuals and entities unless a reduced rate of withholding or a withholding
exemption is provided under the applicable treaty law. Nonresident shareholders
are urged to consult their own tax advisers concerning the applicability of the
United States withholding tax.
 
  Foreign source income received by the International Index Fund and the
Aggregate Bond Index Fund may give rise to withholding and other taxes imposed
by foreign countries. Tax conventions between certain countries and the United
States may reduce or eliminate such taxes. Shareholders of the International
Index Fund may be able to claim U.S. foreign tax credits with respect to such
taxes, subject to certain provisions and limitations contained in the Code. For
example, certain retirement accounts cannot claim foreign tax credits on
investments in foreign securities held by the Fund. The International Index
Fund expects to be eligible, and intends, to file an election with the IRS
pursuant to which shareholders of the Fund will be required to include their
proportionate share of such withholding taxes in their U.S. income tax returns
as gross income, treat such proportionate shares as taxes paid by them, and
deduct such proportionate shares in computing their taxable incomes or,
alternatively, subject to certain restrictions, use them as foreign tax credits
against their U.S. income taxes. No deductions for foreign taxes, however, may
be claimed by noncorporate shareholders who do not itemize deductions. A
shareholder that is a nonresident alien individual or a foreign corporation may
be subject to U.S. withholding tax on the income resulting from the Fund's
election described in this paragraph but may not be able to claim a credit or
deduction against such U.S. tax for the foreign taxes treated as having been
paid by such shareholder. The International Index Fund will report annually to
its shareholders the amount per share of such withholding taxes.
 
  Redemptions and exchanges of a Fund's shares are taxable events, and,
accordingly, shareholders may realize gains or losses on such events. A loss
realized on a sale or exchange of shares of a Fund will be disallowed if other
Fund shares are acquired (whether through the automatic reinvestment of
dividends or otherwise) within a 61-day period beginning 30 days before and
ending 30 days after the date that the shares are disposed of. In such a case,
the basis of the shares acquired will be adjusted to reflect the disallowed
loss.
 
  Under certain provisions of the Code, some shareholders may be subject to a
31% withholding tax on reportable dividends, capital gains distributions and
redemption payments ("backup withholding"). Generally, shareholders subject to
backup withholding will be those for whom a certified taxpayer identification
number is not on file with the Funds or who, to the Funds' knowledge, have
furnished an incorrect number. When establishing an account, an investor must
certify under penalty of perjury that such number is correct and that such
investor is not otherwise subject to backup withholding.

  The foregoing is a general and abbreviated summary of the applicable
provisions of the Code and Treasury regulations presently in effect. For the
complete provisions, reference should be made to the pertinent Code sections
and the Treasury regulations promulgated thereunder. The Code and these
Treasury regulations are subject to change by legislative or administrative
action either prospectively or retroactively.
 
  Ordinary income and capital gains dividends, as well as gains on the sale or
exchange of shares, may also be subject to state and local taxes.
 
  This summary does not discuss the state or local income tax, or the estate or
inheritance tax, consequences of an investment in a Fund.
 
  Shareholders are urged to consult their advisers as to specific questions
regarding Federal, foreign, state or local taxes.
 
  The Series. The Trust and each Fund have received a private letter ruling
from the IRS, in which the IRS has ruled that each Series is classified as a
partnership for tax purposes and, based upon that ruling, that each Fund will
be entitled to look to the underlying assets of the Series in which it has
invested for purposes of satisfying the diversification and other requirements
of the Code applicable to RICs. If any of the facts upon which such ruling is
premised change in any material respect (e.g., if the Trust were required to
register its interests under the Securities Act) and the Trust is unable to
obtain a revised private letter ruling from the IRS indicating that each Series
will continue to be classified as a partnership, then the Board of Directors of
the Corporation will determine, in its discretion, the appropriate course of
action for the Funds. One possible course of action would be to withdraw the
Funds' investments from the Series and to retain an investment adviser to
manage the Funds' assets in accordance with the investment policies applicable
to the respective Fund. See "Investment Objectives and Policies."
 
                             ADDITIONAL INFORMATION
 
DIVIDENDS AND DISTRIBUTIONS
   
  It is each Fund's intention to distribute all of its net investment income,
if any. Dividends from such net investment income are paid at least annually
with respect to each of the S&P 500 Index Fund, Small Cap Index Fund and
International Index Fund. Dividends with respect to the Aggregate Bond Fund are
declared daily and paid monthly. All net realized long- or short-term capital
gains, if any, are distributed to Fund shareholders at least annually.
Dividends will be reduced by account maintenance and transfer agency fees
payable by the shareholders of a Fund. Dividends and distributions will be
reinvested automatically in shares of the Funds, at net asset value.
Shareholders may elect in writing to receive any such dividends or
distributions, or both, in cash. Dividends and distributions are taxable to
shareholder whether they are reinvested in shares of a Fund or received in
cash. From time to time, a Fund may declare a special distribution at or about
the end of the calendar year in order to comply with a Federal income tax
requirement that certain percentages of its ordinary income and capital gains
be distributed during the calendar year.     
 
  See "Shareholder Services--Automatic Reinvestment of Dividends and Capital
Gains Distributions" for information as to how to elect either dividend
reinvestment or cash payments.

DETERMINATION OF NET ASSET VALUE
   
  Net asset value per share is determined once daily as of 15 minutes after the
close of business on the NYSE (generally 4:00 p.m., New York time) on days
during which the NYSE is open for trading (a "Pricing Day"). The net asset
value is computed by dividing the market value of the securities held by a Fund
plus any cash or other assets (including interest and dividends accrued but not
yet received) minus all liabilities (including accrued expenses) by the total
number of shares outstanding at such time. Expenses, including the fees payable
to the Administrator and the Distributor, and the advisory fees payable
indirectly by the Series of the Trust to the Manager, are accrued daily.     
   
  The principal assets of each Fund will normally be its interest of the
underlying Series, which will be valued at its net asset value. A Series'
securities that are traded on stock exchanges are valued at the last sale price
as of the close of business on the day the securities are being valued, or,
lacking any sales, at the closing bid price. In cases where securities are
traded on more than one exchange, the securities are valued on the exchange
designated by or under authority of the Board of Directors as the primary
market. Securities traded in the OTC market are valued at the last quoted bid
prices as at the close of trading on the NYSE on each day by brokers that make
markets in the securities. Securities traded on the NASDAQ national market
system are valued at the last sale price prior to the time of valuation.
Portfolio securities which are traded both in the OTC market and on a stock
exchange are valued according to the broadest and most representative market.
Other investments, including futures contracts and related options, are stated
at market value. Securities and assets for which market quotations are not
readily available are valued at fair market value, as determined in good faith
by or under the direction of the Trustees of the Trust.     
   
  Each investor in the Trust may add to or reduce its investment in any Series
on each Pricing Day. The value of each investor's (including the respective
Funds') interest in a Series will be determined as of 15 minutes after the
close of business on the NYSE (generally 4:00 P.M., New York Time) by
multiplying the net asset value of the Series by the percentage, effective for
that day, that represents that investor's share of the aggregate interests in
such Series. Any additions or withdrawals, which are to be effected on that
day, will then be effected. The investor's percentage of a Series will then be
re-computed as the percentage equal to the fraction (i) the numerator of which
is the value of such investor's investment in the Series as of the time or
determination on such day plus or minus, as the case may be, the amount of any
additions to or withdrawals from the aggregate investments in the Series by all
investors in the Series effected on such day, and (ii) the denominator of which
is the aggregate net asset value of the Series as of such time on such day plus
or minus, as the case may be, the amount of the net additions to or withdrawals
from the aggregate investments in the Series by all investors in the Series.
The percentage so determined will then be applied to determine the value of the
investor's interest in such Series as of 15 minutes after the close of business
of the NYSE on the next Pricing Day of the Series.     
 
ORGANIZATION OF THE CORPORATION
 
  The Corporation is a Maryland corporation incorporated on October 25, 1996.
It has an authorized capital of 1,000,000,000 shares of Common Stock, par value
$0.0001 per share, divided into 125,000,000 shares each of Class A and Class D
shares for each of the four Funds: Merrill Lynch S&P 500 Index Fund, Merrill
Lynch Small Cap Index Fund, Merrill Lynch Aggregate Bond Index Fund and Merrill
Lynch International Index Fund. Class A and Class D shares of a Fund represent
interests in the same assets of the
 
                                       31
<PAGE>
 
Series and are identical in all respects except that the Class D shares bear
certain expenses related to the account maintenance associated with such
shares. Class D shares have exclusive voting rights with respect to matters
relating to the class' account maintenance expenditures.
 
  Shareholders are entitled to one vote for each full share held and to
fractional votes for fractional shares held in the election of Directors (to
the extent hereafter provided) and on other matters submitted to the vote of
shareholders. All shares of each Fund have equal voting rights, except that
each Fund has exclusive voting rights to matters affecting only such Fund, and
except that as noted above, Class D shares have exclusive voting rights with
respect to matters relating to the class' account maintenance expenditures.
There normally will be no meeting of shareholders for the purpose of electing
Directors unless and until such time as less than a majority of the Directors
holding office have been elected by the shareholders, at which time the
Directors then in office will call a shareholders' meeting for the election of
Directors. Shareholders may, in accordance with the terms of the Articles of
Incorporation, cause a meeting of shareholders to be held for the purpose of
voting on the removal of Directors. Also, the Corporation will be required to
call a special meeting of shareholders in accordance with the requirements of
the Investment Company Act to seek approval of new management and advisory
arrangements, of a material increase in account maintenance fees or of a change
in fundamental policies, objectives or restrictions. Except as set forth above,
the Directors shall continue to hold office and appoint successor Directors.
Each issued and outstanding share is entitled to participate equally in
dividends and distributions declared and in net assets upon liquidation or
dissolution remaining after satisfaction of outstanding liabilities, except
that, as noted above, Class D shares bear certain additional expenses. Shares
issued are fully-paid and non-assessable by the Fund. Voting rights for
Directors are not cumulative.
 
  The Trust consists of four Series, and is organized as a Delaware business
trust. Whenever investors in a Series are requested to vote on a fundamental
policy of a Series, the Corporation will hold a meeting of its shareholders and
will cast its vote as instructed by such shareholders.
 
SHAREHOLDER INQUIRIES
 
  Shareholder inquiries may be addressed to the Funds at the address or
telephone number set forth on the cover page of this Prospectus.
 
SHAREHOLDER REPORTS
 
  Only one copy of each shareholder report and certain shareholder
communications will be mailed to each identified shareholder regardless of the
number of accounts such shareholder has. If a shareholder wishes to receive
separate copies of each report and communication for each of the shareholder's
related accounts the shareholder should notify in writing:
 
    Merrill Lynch Financial Data Services, Inc.
    P.O. Box 45289
    Jacksonville, Florida 32232-5289
 
  The written notification should include the shareholder's name, address, tax
identification number and Merrill Lynch and/or mutual fund account numbers. If
you have any questions regarding this please call your Merrill Lynch financial
consultant or Merrill Lynch Financial Data Services, Inc. at 800-637-3863.

                                   APPENDIX A
 
  The Series are authorized to use certain instruments, including indexed
securities, options, futures and swaps, as described below. Such instruments,
which may be regarded as derivatives, are referred to collectively herein as
"Strategic Instruments."
 
INDEXED SECURITIES
 
  The Series may invest in securities the potential return of which is based on
the change in particular measurements of value or rate (an "index"). As an
illustration, a Series may invest in a debt security that pays interest and
returns principal based on the change in the value of a securities index or a
basket of securities, or based on the relative changes of two indices. If a
Series invests in such securities, it may be subject to reduced or eliminated
interest payments or loss of principal in the event of an adverse movement in
the relevant index or indices.
 
OPTIONS ON SECURITIES AND SECURITIES INDICES
 
  Purchasing Options. Each Series is authorized to purchase put options on
securities held in its portfolio or securities indices the performance of which
is substantially replicated by securities held in its portfolio. When a Series
purchases a put option, in consideration for an upfront payment (the "option
premium") the Series acquires a right to sell to another party specified
securities owned by the Series at a specified price (the "exercise price") on
or before a specified date (the "expiration date"), in the case of an option on
securities, or to receive from another party a payment based on the amount a
specified securities index declines below a specified level on or before the
expiration date, in the case of an option on a securities index. The purchase
of a put option limits the Series' risk of loss in the event of a decline in
the market value of the portfolio holdings underlying the put option prior to
the option's expiration date. If the market value of the portfolio holdings
associated with the put option increases rather than decreases, however, the
Series will lose the option premium and will consequently realize a lower
return on the portfolio holdings than would have been realized without the
purchase of the put.
 
  Each Series is also authorized to purchase call options on securities it
intends to purchase or securities indices. When a Series purchases a call
option, in consideration for the option premium the Series acquires the right
to purchase from another party specified securities at the exercise price on or
before the expiration date, in the case of an option on securities, or to
receive from another party a payment based on the amount a specified securities
index increases beyond a specified level on or before the expiration date, in
the case of an option on a securities index. The purchase of a call option may
protect the Series from having to pay more for a security as a consequence of
increases in the market value for the security during a period when the Series
is contemplating its purchase, in the case of an option on a security, or
attempting to identify specific securities in which to invest in a market the
Series believes to be attractive, in the case of an option on an index (an
"anticipatory hedge"). In the event the Series determines not to purchase a
security underlying a call option, however, the Series may lose the entire
option premium.
 
  Each Series is also authorized to purchase put or call options in connection
with closing out put or call options it has previously sold.
 
 
                                      A-1

  Writing Options. Each Series is authorized to write (i.e., sell) call options
on securities held in its portfolio or securities indices, the performance of
which is substantially correlated to securities held in its portfolio. When a
Series writes a call option, in return for an option premium the Series gives
another party the right to buy specified securities owned by the Series at the
exercise price on or before the expiration date, in the case of an option on
securities, or agrees to pay to another party an amount based on any gain in a
specified securities index beyond a specified level on or before the expiration
date, in the case of an option on a securities index. In the event the party to
which a Series has written an option fails to exercise its rights under the
option because the value of the underlying securities is less than the exercise
price, the Series will partially offset any decline in the value of the
underlying securities through the receipt of the option premium. By writing a
call option, however, a Series limits its ability to sell the underlying
securities, and gives up the opportunity to profit from any increase in the
value of the underlying securities beyond the exercise price, while the option
remains outstanding.     
 
  Each Series may also write put options on securities or securities indices.
When a Series writes a put option, in return for an option premium the Series
gives another party the right to sell to the Series a specified security at the
exercise price on or before the expiration date, in the case of an option on a
security, or agrees to pay to another party an amount based on any decline in a
specified securities index below a specified level on or before the expiration
date, in the case of an option on a securities index. In the event the party to
which the Series has written an option fails to exercise its rights under the
option because the value of the underlying securities is greater than the
exercise price, the Series will profit by the amount of the option premium. By
writing a put option, however, a Series will be obligated to purchase the
underlying security at a price that may be higher than the market value of the
security at the time of exercise as long as the put option is outstanding, in
the case of an option on a security, or make a cash payment reflecting any
decline in the index, in the case of an option on an index. Accordingly, when
the Series writes a put option it is exposed to a risk of loss in the event the
value of the underlying securities falls below the exercise price, which loss
potentially may substantially exceed the amount of option premium received by
the Series for writing the put option. A Series will write a put option on a
security or a securities index only if the Series would be willing to purchase
the security at the exercise price for investment purposes (in the case of an
option on a security) or is writing the put in connection with trading
strategies involving combinations of options--for example, the sale and
purchase of options with identical expiration dates on the same security or
index but different exercise prices (a technique called a "spread").
 
  Each Series is also authorized to sell call or put options in connection with
closing out call or put options it has previously purchased.
   
  Other than with respect to closing transactions, the Series will only write
call or put options that are "covered." A put option will be considered covered
if a Series has segregated assets with respect to such option in the manner
described in "Risk Factors in Strategic Instruments" below. A call option will
be considered covered if a Series owns the securities it would be required to
deliver upon exercise of the option (or, in the case of option on a securities
index, securities which substantially replicate the performance of such index)
or owns a call option, warrant or convertible instrument which is immediately
exercisable for, or convertible into, such security.     
 
  Types of Options. Each Series may engage in transactions in options on
securities or securities indices on exchanges and in the over-the-counter
("OTC") markets. In general, exchange-traded options have
 
                                      A-2
<PAGE>
 
standardized exercise prices and expiration dates and require the parties to
post margin against their obligations, and the performance of the parties'
obligations in connection with such options is guaranteed by the exchange or a
related clearing corporation. OTC options have more flexible terms negotiated
between the buyer and seller, but generally do not require the parties to post
margin and are subject to greater risk of counterparty default. See "Additional
Risk Factors of OTC Transactions" below.
 
FUTURES
 
  Each Series may engage in transactions in futures and options thereon.
Futures are standardized, exchange-traded contracts which obligate a purchaser
to take delivery, and a seller to make delivery, of a specific amount of a
commodity at a specified future date at a specified price. No price is paid
upon entering into a futures contract. Rather, upon purchasing or selling a
futures contract the Series is required to deposit collateral ("margin") equal
to a percentage (generally less than 10%) of the contract value. Each day
thereafter until the futures position is closed, the Series will pay additional
margin representing any loss experienced as a result of the futures position
the prior day or be entitled to a payment representing any profit experienced
as a result of the futures position the prior day. The Series will further
limit transactions in futures and options on futures to the extent necessary to
prevent the Series from being deemed a "commodity pool" under regulations of
the Commodity Futures Trading Commission.
 
SWAPS
 
  The Series are authorized to enter into equity swap agreements, which are OTC
contracts in which one party agrees to make periodic payments based on the
change in market value of a specified equity security, basket of equity
securities or equity index in return for periodic payments based on a fixed or
variable interest rate or the change in market value of a different equity
security, basket of securities or equity index. Swap agreements may also be
used to obtain exposure to an equity or market without owning or taking
physical custody of securities in circumstances in which direct investment is
restricted by local law or is otherwise impractical.
 
RISK FACTORS IN STRATEGIC INSTRUMENTS
 
  The Series intend to enter into transactions involving Strategic Instruments
only if there appears to be a liquid secondary market for such instruments or,
in the case of illiquid instruments traded in OTC transactions, such
instruments satisfy the criteria set forth below under "Additional Risk Factors
of OTC Transactions." However, there can be no assurance that, at any specific
time, either a liquid secondary market will exist for a Strategic Instrument or
a Series will otherwise be able to sell such instrument at an acceptable price.
It may therefore not be possible to close a position in a Strategic Instrument
without incurring substantial losses, if at all.
   
  Certain transactions in Strategic Instruments (e.g., futures transactions,
sales of put options) may expose a Series to potential losses which exceed the
amount originally invested by the Series in such instruments. When a Series
engages in such a transaction, the Series will deposit in a segregated account
at its custodian liquid securities with a value at least equal to the Series'
exposure, on a marked-to-market basis, to the transaction (as calculated
pursuant to requirements of the Securities and Exchange Commission). Such     
 
                                      A-3
<PAGE>
 
segregation will ensure that the Series has assets available to satisfy its
obligations with respect to the transaction, but will not limit the Series'
exposure to loss.
 
ADDITIONAL RISK FACTORS OF OTC TRANSACTIONS; LIMITATIONS ON THE USE OF OTC
STRATEGIC INSTRUMENTS
 
  Certain Strategic Instruments traded in OTC markets, including indexed
securities, swaps and OTC options, may be substantially less liquid than other
instruments in which a Series may invest. The absence of liquidity may make it
difficult or impossible for a Series to sell such instruments promptly at an
acceptable price. The absence of liquidity may also make it more difficult for
the Series to ascertain a market value for such instruments. A Series will
therefore acquire illiquid OTC instruments (i) if the agreement pursuant to
which the instrument is purchased contains a formula price at which the
instrument may be terminated or sold, or (ii) for which the Manager anticipates
the Series can receive on each business day at least two independent bids or
offers, unless a quotation from only one dealer is available, in which case
that dealer's quotation may be used.
 
  The staff of the Securities and Exchange Commission has taken the position
that purchased OTC options and the assets underlying written OTC options are
illiquid securities. The Series have therefore adopted an investment policy
pursuant to which they will not purchase or sell OTC options (including OTC
options on futures contracts) if, as a result of such transactions, the sum of
the market value of OTC options currently outstanding which are held by the
Series, the market value of the securities underlying OTC call options
currently outstanding which have been sold by the Series and margin deposits on
the Series' outstanding OTC options exceeds 15% of the total assets of the
Series, taken at market value, together with all other assets of the Series
which are deemed to be illiquid or are otherwise not readily marketable.
However, if an OTC option is sold by the Series to a dealer in U.S. government
securities recognized as a "primary dealer" by the Federal Reserve Bank of New
York and the Series has the unconditional contractual right to repurchase such
OTC option at a predetermined price, then the Series will treat as illiquid
such amount of the underlying securities as is equal to the repurchase price
less the amount by which the option is "in-the-money" (i.e., current market
value of the underlying security minus the option's exercise price).
 
  Because Strategic Instruments traded in OTC markets are not guaranteed by an
exchange or clearing corporation and generally do not require payment of
margin, to the extent that a Series has unrealized gains in such instruments or
has deposited collateral with its counterparty the Series is at risk that its
counterparty will become bankrupt or otherwise fail to honor its obligations.
The Series will attempt to minimize the risk that a counterparty will become
bankrupt or otherwise fail to honor its obligations by engaging in transactions
in Strategic Instruments traded in OTC markets only with financial institutions
which have substantial capital or which have provided the Series with a third-
party guaranty or other credit enhancement.
 
ADDITIONAL LIMITATIONS ON THE USE OF STRATEGIC INSTRUMENTS
 
  The Series may not use any Strategic Instrument to gain exposure to an asset
or class of assets that it would be prohibited by its investment restrictions
from purchasing directly.

          APPENDIX B--DESCRIPTION OF COMMERCIAL PAPER AND BOND RATINGS
 
COMMERCIAL PAPER
 
  Description of relevant commercial paper ratings of Standard & Poor's Ratings
Group ("S&P") are as follows:
 
    A-1: This highest category indicates that the degree of safety regarding
  timely payment is strong. Those issues determined to possess extremely
  strong safety characteristics are denoted with a plus (+) sign designation.
 
    A-2: Capacity for timely payment on issues with this designation is
  satisfactory. However, the relative degree of safety is not as high as for
  issues designated A-1.
 
    A-3: Issues carrying this designation have an adequate capacity for
  timely payment. They are, however, somewhat more vulnerable to the adverse
  effects of changes in circumstances than obligations carrying the higher
  designations.
 
  Description of the relevant commercial paper ratings of Moody's Investors
Service, Inc. ("Moody's") are as follows:
 
    PRIME-1: Issuers rated Prime-1 (or supporting institutions) have a
  superior ability for repayment of senior short-term debt obligations.
  Prime-1 repayment ability will often be evidenced by many of the following
  characteristics:
 
    --Leading market positions in well-established industries.
 
    --High rates of return on funds employed.
 
    --Conservative capitalization structure with moderate reliance on debt
  and ample asset protection.
 
    --Broad margins in earnings coverage of fixed financial charges and high
  internal cash generation.
 
    --Well-established access to a range of financial markets and assured
  sources of alternate liquidity.
 
    PRIME-2: Issuers rated Prime-2 (or supporting institutions) have a strong
  ability for repayment of senior short-term debt obligations. This will
  normally be evidenced by many of the characteristics cited above but to a
  lesser degree. Capitalization characteristics, while still appropriate, may
  be more affected by external conditions. Ample alternate liquidity is
  maintained.
 
    PRIME-3: Issuers rated Prime-3 (or supporting institutions) have an
  acceptable ability for repayment of senior short-term obligations. The
  effect of industry characteristics and market compositions may be more
  pronounced. Variability in earnings and profitability may result in changes
  in the level of debt protection measurement and may require relatively high
  financial leverage. Adequate alternate liquidity is maintained.
 
CORPORATE BONDS
 
  Descriptions of the bond ratings of S&P are:
 
  AAA--Debt rated AAA has the highest rating assigned by Standard & Poor's.
Capacity to pay interest and repay principal is extremely strong.
 
 
                                      A-5
<PAGE>
 
  AA--Debt rated AA has a very strong capacity to pay interest and repay
principal and differs from the higher rated issues only in small degree.
 
  A--Debt rated A has a strong capacity to pay interest and repay principal
although it is somewhat more susceptible to the adverse effects of changes in
circumstances and economic conditions than debt in higher rated categories.
 
  BBB--Debt rated BBB is regarded as having an adequate capacity to pay
interest and repay principal. Whereas it normally exhibits adequate protection
parameters, adverse economic conditions or changing circumstances are more
likely to lead to a weakened capacity to pay interest and repay principal for
debt in this category than for debt in higher rated categories.
 
  BB, B, CCC, CC or C--Debt rated BB, B, CCC, CC or C is regarded, on balance,
as predominantly speculative with respect to the issuer's capacity to pay
interest and repay principal in accordance with the terms of the obligation.
While such debt will likely have some quality and protective characteristics,
these are outweighed by large uncertainties or major risk exposures to adverse
debt conditions.
 
  C1--The rating C1 is reserved for income bonds on which no interest is being
paid.
 
  D--Debt rated D is in default and payment of interest and/or repayment of
principal is in arrears.
 
  The ratings from AA to CC may be modified by the addition of a plus (+) or
minus (-) sign to show relative standing within the major rating categories.
 
  Descriptions of the bond ratings of Moody's are as follows:
 
  Aaa--Bonds which are rated Aaa are judged to be of the best quality. They
carry the smallest degree of investment risk and are generally referred to as
"gilt edge." Interest payments are protected by a large or by an exceptionally
stable margin, and principal is secure. While the various protective elements
are likely to change, such changes as can be visualized are more unlikely to
impair the fundamentally strong position of such issues.
 
  Aa--Bonds which are rated Aa are judged to be of high quality by all
standards. Together with the Aaa group they comprise what are generally known
as high grade bonds. They are rated lower than the best bonds because margins
of protection may not be as large as in Aaa securities or fluctuation of
protective elements may be of greater amplitude or there may be other elements
present which make the long-term risks appear somewhat greater than the Aaa
securities.
 
  A--Bonds which are rated A possess many favorable investment attributes and
are to be considered as upper-medium-grade obligations. Factors giving security
to principal and interest are considered adequate, but elements may be present
which suggest a susceptibility to impairment some time in the future.
 
  Baa--Bonds which are rated Baa are considered as medium grade obligations,
i.e., they are neither highly protected nor poorly secured. Interest payments
and principal security appear adequate for the present, but certain protective
elements may be lacking or may be characteristically unreliable over any great
length
 
                                      A-6
<PAGE>
 
of time. Such bonds lack outstanding investment characteristics and in fact
have speculative characteristics as well.
 
  Ba--Bonds which are rated Ba are judged to have speculative elements; their
future cannot be considered as well assured. Often the protection of interest
and principal payments may be very moderate and thereby not well safeguarded
during both good and bad times over the future. Uncertainty of position
characterizes bonds in this class.
 
  B--Bonds which are rated B generally lack characteristics of the desirable
investment. Assurance of interest and principal payments or of maintenance of
other terms of the contract over any long period of time may be small.
 
  Caa--Bonds which are rated Caa are of poor standing. Such issues may be in
default or there may be present elements of danger with respect to principal or
interest.
 
  Ca--Bonds which are rated Ca represent obligations which are speculative to a
high degree. Such issues are often in default or have other marked
shortcomings.
 
  C--Bonds which are rated C are the lowest class of bonds and issues so rated
can be regarded as having extremely poor prospects of ever attaining any real
investment standing.
 
  Moody's applies modifiers to each rating classification from Aa through B to
indicate relative ranking within its rating categories. The modifier "1"
indicates that a security ranks in the higher end of its rating category; the
modifier "2" indicates a mid-range ranking; and the modifier "3" indicates that
the issue ranks in the lower end of its rating category.

  Merrill Lynch Index Funds, Inc. (the "Corporation") currently consists of
four portfolios or series: Merrill Lynch S&P 500 Index Fund ("S&P 500 Index
Fund"), Merrill Lynch Small Cap Index Fund ("Small Cap Index Fund"), Merrill
Lynch Aggregate Bond Index Fund ("Aggregate Bond Index Fund") and Merrill Lynch
International Index Fund ("International Index Fund") (collectively, the
"Funds," and each, a "Fund"). Each Fund is a non-diversified mutual fund whose
investment objective is to provide investment results that, before expenses,
seek to replicate the total return (i.e., the combination of capital changes
and income) of a specified securities index. Each Fund will seek to achieve its
objective by investing all of its assets in the series (collectively, the
"Series," and each, a "Series") of Merrill Lynch Index Trust (the "Trust") that
has the same investment objective as the Fund. Each Fund's investment
experience will correspond directly to the investment experience of the
respective Series in which it invests. There can be no assurance that the
investment objectives of the Funds will be achieved.
 
  Each Fund offers two classes of shares, Class A shares and Class D shares.
Class A shares of each Fund are offered at a price equal to the next determined
net asset value per share without the imposition of any front-end or deferred
sales charge, and are not subject to any ongoing account maintenance or
distribution fee. Distribution of Class A shares of each Fund is limited to
certain eligible investors. Class D shares of each Fund are offered at a price
equal to the next determined net asset value per share without the imposition
of any front-end or deferred sales charge and are not subject to any ongoing
distribution fee, but are subject to an ongoing account maintenance fee at an
annual rate of 0.25% of average daily net assets.
   
  This Statement of Additional Information for the Funds is not a prospectus
and should be read in conjunction with the prospectus of the Funds, dated
September 3, 1997 (the "Prospectus"), which has been filed with the Securities
and Exchange Commission and can be obtained, without charge, by calling or by
writing the Funds at the above telephone number or address. This Statement of
Additional Information has been incorporated by reference into the Prospectus.

                       INVESTMENT OBJECTIVES AND POLICIES
   
  Merrill Lynch Index Funds, Inc. currently consists of four series: S&P 500
Index Fund, Small Cap Index Fund, Aggregate Bond Index Fund and International
Index Fund. Each Fund is a non-diversified mutual fund whose investment
objective is to provide investment results that, before expenses, seek to
replicate the total return (i.e., the combination of capital changes and
income) of a specified securities index. Each Fund will seek to achieve its
objective by investing all of its assets in the Series of Merrill Lynch Index
Trust that has the same investment objective as the Fund. Each Fund's
investment experience will correspond directly to the investment experience of
the respective Series in which it invests. Reference is made to the discussion
under "Investment Objectives and Policies" in the Prospectus for information
with respect to each Fund's and each Series' investment objective and policies.
There can be no assurance that the investment objectives of the Funds will be
achieved.     
 
  The Funds' and Series' investment objectives are not fundamental policies,
and may be changed by the Directors of the Corporation and the Trustees of the
Trust, respectively, without shareholder approval. THE TRUSTEES AND THE
DIRECTORS MAY ALSO CHANGE THE TARGET INDEX OF ANY RESPECTIVE SERIES AND FUND IF
THEY CONSIDER THAT A DIFFERENT INDEX WOULD FACILITATE THE MANAGEMENT OF THE
SERIES AND FUND IN A MANNER WHICH BETTER ENABLES THE FUND AND SERIES TO SEEK TO
REPLICATE THE TOTAL RETURN OF THE MARKET SEGMENT REPRESENTED BY THE CURRENT
INDEX.
 
INVESTMENT RESTRICTIONS
 
  The Corporation has adopted the following restrictions and policies relating
to the investment of each Fund's assets and activities, which are fundamental
policies and may not be changed with respect to a Fund without the approval of
the holders of a majority of the Fund's outstanding voting securities (which
for this purpose and under the Investment Company Act of 1940, as amended (the
"Investment Company Act") means the lesser of (i) 67% of the shares represented
at a meeting at which more than 50% of the outstanding shares are represented
or (ii) more than 50% of the outstanding shares). Provided that none of the
following restrictions shall prevent a Fund from investing all of its assets in
shares of another registered investment company with the same investment
objective (in a master/feeder structure), each Fund may not:
 
    1. Make any investment inconsistent with the Fund's classification as a
  non-diversified company under the Investment Company Act.
 
    2. Invest more than 25% of its assets, taken at market value, in the
  securities of issuers in any particular industry (excluding the U.S.
  Government and its agencies and instrumentalities); provided, that in
  replicating the weighting of a particular industry in its target index, a
  Series or Fund may invest more that 25% of its total assets in securities
  of issuers in that industry.
 
    3. Make investments for the purpose of exercising control or management.
 
    4. Purchase or sell real estate, except that, to the extent permitted by
  applicable law, a Fund may invest in securities directly or indirectly
  secured by real estate or interests therein or issued by companies which
  invest in real estate or interests therein.
 
    5. Make loans to other persons, except that the acquisition of bonds,
  debentures or other corporate debt securities and investment in government
  obligations, commercial paper, pass-through instruments,
 
                                       2
<PAGE>
 
  certificates of deposit, bankers' acceptances, repurchase agreements or any
  similar instruments shall not be deemed to be the making of a loan, and
  except further that a Fund may lend its portfolio securities, provided that
  the lending of portfolio securities may be made only in accordance with
  applicable law and the guidelines set forth in the Fund's Prospectus and
  Statement of Additional Information, as they may be amended from time to
  time.
 
    6. Issue senior securities to the extent such issuance would violate
  applicable law.
 
    7. Borrow money, except that (i) a Fund may borrow from banks (as defined
  in the Investment Company Act) in amounts up to 33 1/3% of its total assets
  (including the amount borrowed), (ii) a Fund may borrow up to an additional
  5% of its total assets for temporary purposes, (iii) a Fund may obtain such
  short-term credit as may be necessary for the clearance of purchases and
  sales of portfolio securities and (iv) the Fund may purchase securities on
  margin to the extent permitted by applicable law. A Fund may not pledge its
  assets other than to secure such borrowings or, to the extent permitted by
  the Fund's investment policies as set forth in the Fund's Prospectus and
  Statement of Additional Information, as they may be amended from time to
  time, in connection with hedging transactions, short sales, when-issued and
  forward commitment transactions and similar investment strategies.
 
    8. Underwrite securities of other issuers except insofar as a Fund
  technically may be deemed an underwriter under the Securities Act in
  selling portfolio securities.
 
    9. Purchase or sell commodities or contracts on commodities, except to
  the extent that a Fund may do so in accordance with applicable law and the
  Fund's Prospectus and Statement of Additional Information, as they may be
  amended from time to time, and without registering as a commodity pool
  operator under the Commodity Exchange Act.
 
  The Trust has adopted investment restrictions substantially identical to the
foregoing, which are fundamental policies of the Trust and may not be changed
with respect to any Series without the approval of the holders of a majority of
the interests of the Series.
 
  In addition, the Trust and the Corporation have adopted as an operating
policy, which may be changed by the Trustees and the Directors without
shareholder approval, that no Series or Fund, respectively, will make any
additional investments if the amount of its borrowings exceeds 5% of its total
assets. Borrowings do not include the use of investment techniques that may be
deemed to create leverage, including, but not limited to, such techniques as
dollar rolls, when-issued securities, options and futures.
 
  Portfolio securities of each Fund's underlying Series generally may not be
purchased from, sold or loaned to Merrill Lynch Asset Management, L.P. ("MLAM")
or its affiliates or any of their directors, officers or employees, acting as
principal, unless pursuant to a rule or exemptive order under the Investment
Company Act.
 
  Because of the affiliation of MLAM with the Corporation, the Series are
prohibited from engaging in certain transactions involving MLAM's affiliate,
Merrill Lynch, Pierce, Fenner & Smith Incorporated ("Merrill Lynch"), or its
affiliates except for brokerage transactions permitted under the Investment
Company Act involving only usual and customary commissions or transactions
pursuant to an exemptive order under the Investment Company Act. See "Portfolio
Transactions and Brokerage." Without such an exemptive order, the Series are
prohibited from engaging in portfolio transactions with Merrill Lynch or its
affiliates acting as principal and from purchasing securities in public
offerings which are not registered under the Securities Act in which such firms
or any of their affiliates participate as an underwriter or dealer.

$250 per Board meeting attended, together with such individual's actual out-
of-pocket expenses relating to attendance at meetings. The Corporation and the

ADMINISTRATION ARRANGEMENTS
 
  MLAM is owned and controlled by Merrill Lynch & Co., Inc., a financial
services holding company and the parent of Merrill Lynch. Reference is made to
"Management of the Funds" in the Prospectus for certain information concerning
the administration arrangements of the Corporation and the management and
advisory arrangements of the Trust.
 
  The Corporation has entered into an administration agreement with MLAM as
Administrator (the "Administration Agreement"). As discussed in the
Prospectus, the Administrator receives for its services to the Funds monthly
compensation at the annual rates of the average daily net assets of each Fund
as follows:
 
<TABLE>

                                       5
<PAGE>
 
   
  For the period April 3, 1997 (commencement of operations) to June 30, 1997,
the total fee paid by the S&P 500 Index Fund and the Aggregate Bond Index Fund
to the Administrator was $94,046 and $28,078, respectively. For the period
April 9, 1997 (commencement of operations) to June 30, 1997, the total fee paid
by Small Cap Index Fund and the International Index Fund to the Administrator
was $16,520 and $50,554, respectively.     
 
  The Administration Agreement obligates the Administrator to provide certain
administrative services to the Corporation and the Funds and to pay all
compensation of and furnish office space for officers and employees of the
Corporation as well as the fees of all Directors who are affiliated persons of
the Administrator or any of their affiliates. Each Fund pays all other expenses
incurred in the operation of the Fund, including, among other things, taxes,
expenses for legal and auditing services, costs of printing proxies, stock
certificates, shareholder reports and prospectuses and statements of additional
information (except to the extent paid by the Distributor), charges of the
Custodian, any Sub-custodian and Transfer Agent, expenses of redemption of
shares, Securities and Exchange Commission fees, expenses of registering the
shares under federal, state or foreign laws, fees and expenses of unaffiliated
Directors, accounting and pricing costs (including the daily calculation of net
asset value), insurance, interest, brokerage costs, litigation and other
extraordinary or non-recurring expenses, and other expenses properly payable by
the Corporation or the Fund. Merrill Lynch Funds Distributor, Inc. (the
"Distributor") will pay the promotional expenses of the Funds incurred in
connection with the offering of its shares.
   
  Duration and Termination. Unless earlier terminated as described below, the
Administration Agreement will remain in effect for two years from the date of
its adoption. Thereafter, it will remain in effect from year to year with
respect to each Fund if approved annually (a) by the Board of Directors and (b)
by a majority of the Directors who are not parties to such contract or
interested persons (as defined in the Investment Company Act) of any such
party. Such contract is not assignable and may be terminated with respect to a
Fund without penalty on 60 days' written notice at the option of either party
thereto or by the vote of the shareholders of the Fund.     
 
MANAGEMENT AND ADVISORY ARRANGEMENTS
 
  Each Fund invests all of its assets in shares of the corresponding Series of
the Trust. Accordingly, the Funds do not invest directly in portfolio
securities and do not require investment advisory services. All portfolio
management occurs at the level of the Trust. The Trust has entered into a
management agreement with MLAM as Manager (the "Management Agreement"). As
discussed in the Prospectus, the Manager receives for its services to the
Series monthly compensation at the annual rates of the average daily net assets
of each Series as follows:
 
<TABLE>

         NAME OF SERIES                                           MANAGEMENT FEE

  For the period April 3, 1997 (commencement of operations) to June 30, 1997,
the fee earned by the Manager, from the S&P 500 Index Series, and the Aggregate
Bond Index Series was $23,504 and $12,712, respectively (based on average net
assets of approximately $195.0 million and $83.2 million, respectively), all of
which was voluntarily waived. For the period April 9, 1997 (commencement of
operations) to June 30,     
 
                                       6
<PAGE>
 
   
1997, the fee earned by the Manager, from the Small Cap Index Series and the
International Index Series was $6,005 and $23,163, respectively (based on
average net assets of approximately $33.4 million and $93.8 million,
respectively), all of which was voluntarily waived.     
       
  The Management Agreement obligates the Manager to provide investment advisory
services and to pay all compensation of and furnish office space for officers
and employees of the Trust connected with investment and economic research,
trading and investment management of the Trust, as well as the fees of all
Trustees who are affiliated persons of the Manager or any of their affiliates.
Each Series pays all other expenses incurred in the operation of the Series,
including, among other things, taxes, expenses for legal and auditing services,
costs of printing proxies, stock certificates, shareholder reports and
prospectuses and statements of additional information (except to the extent
paid by the Distributor), charges of the Custodian, any Sub-custodian and
Transfer Agent, expenses of redemption of shares, Securities and Exchange
Commission fees, expenses of registering the shares under federal, state or
foreign laws, fees and expenses of unaffiliated Trustees, accounting and
pricing costs (including the daily calculation of net asset value), insurance,
interest, brokerage costs, litigation and other extraordinary or non-recurring
expenses, and other expenses properly payable by the Trust or the Series. The
Distributor will pay the promotional expenses of the Trust incurred in
connection with the offering of its shares.
 
  Securities held by the Series of the Trust may also be held by, or be
appropriate investments for, other funds or investment advisory clients for
which the Manager or its affiliates act as an adviser. Because of different
objectives or other factors, a particular security may be bought for one or
more clients when one or more clients are selling the same security. If
purchases or sales of securities by the Manager for the Series or other funds
for which it acts as investment adviser or for its advisory clients arise for
consideration at or about the same time, transactions in such securities will
be made, insofar as feasible, for the respective funds and clients in a manner
deemed equitable to all. To the extent that transactions on behalf of more than
one client of the Manager or its affiliates during the same period may increase
the demand for securities being purchased or the supply of securities being
sold, there may be an adverse effect on price.
 
  Duration and Termination. Unless earlier terminated as described below, the
Management Agreement will remain in effect for two years from the date of its
adoption. Thereafter, it will remain in effect from year to year with respect
to each Series if approved annually (a) by the Board of Trustees or by a
majority of the outstanding shares of the Series and (b) by a majority of the
Trustees who are not parties to such contract or interested persons (as defined
in the Investment Company Act) of any such party. Such contract is not
assignable and may be terminated with respect to a Series without penalty on 60
days' written notice at the option of either party thereto or by the vote of
the shareholders of the Series.
 
                               PURCHASE OF SHARES
 
  Reference is made to "Purchase of Shares" in the Prospectus for certain
information as to the purchase of Fund shares.
 
  The Corporation has entered into a distribution agreement with the
Distributor in connection with the offering of shares of the Funds (the
"Distribution Agreement"). The Distribution Agreement obligates the Distributor
to pay certain expenses in connection with the offering of the shares of the
Funds. After the
 
                                       7
<PAGE>
 
prospectuses, statements of additional information and periodic reports have
been prepared, set in type and mailed to shareholders, the Distributor pays for
the printing and distribution of copies thereof used in connection with the
offering to dealers and investors. The Distributor also pays for other
supplementary sales literature and advertising costs. The Distribution
Agreement is subject to the same renewal requirements and termination
provisions as the Management Agreement described above.
 
  The Corporation reserves the right to suspend the offering of its shares at
any time.
 
  Account Maintenance Plan. Reference is made to "Purchase of Shares--Account
Maintenance Plan" in the Prospectus for certain information with respect to the
Account Maintenance Plan (the "Plan") of the Class D shares of the Funds.
   
  The payment of the account maintenance fee is subject to the provisions of
Rule 12b-1 under the Investment Company Act. Among other things, the Plan
provides that the Distributor shall provide and the Directors shall review
quarterly reports of the disbursement of the account maintenance fees paid to
the Distributor. In their consideration of the Plan, the Directors must
consider all factors they deem relevant, including information as to the
benefits of the Plan to the Funds and their shareholders. The Plan further
provides that, so long as the Plan remains in effect, the selection and
nomination of Directors who are not "interested persons" of the Funds, as
defined in the Investment Company Act (the "Independent Directors"), shall be
committed to the discretion of the Independent Directors then in office. In
approving the Plan in accordance with Rule 12b-1, the Independent Directors
concluded that there is reasonable likelihood that the Plan will benefit the
Fund and its shareholders. The Plan can be terminated at any time, without
penalty, by the vote of a majority of the Independent Directors or with respect
to any Fund by the vote of the holders of a majority of the outstanding Class D
shares of the Fund. The Plan cannot be amended to increase materially the
amount to be spent by the Class D shares of a Fund without shareholder
approval, and all material amendments are required to be approved by the vote
of Directors, including a majority of the Independent Directors who have no
direct or indirect financial interest in the Plan, cast in person at a meeting
called for that purpose. Rule 12b-1 further requires that the Fund preserve
copies of the Plan and any report made pursuant to such plan for a period of
not less than six years from the date of the Plan or such report, the first two
years in an easily accessible place. During the period April 3, 1997
(commencement of operations) to June 30, 1997, the S&P 500 Index Fund and the
Aggregate Bond Index Fund paid the Distributor $30,273 and $15,931,
respectively, pursuant to the Plan (based on average daily net assets subject
to such Class D Plan of approximately $50.2 million and $26.4 million,
respectively), all of which was paid to Merrill Lynch for providing account
maintenance activities in connection with Class D shares. During the period
April 9, 1997 (commencement of operations) to June 30, 1997, the Small Cap
Index Fund and the International Index Fund paid the Distributor $10,709, and
$14,371, respectively, pursuant to the Plan (based on average daily net assets
subject to such Class D Plan of approximately $19.1 million, and $25.6 million,
respectively), all or which was paid to Merrill Lynch for providing account
maintenance activities in connection with Class D shares).     
 
                              REDEMPTION OF SHARES
 
  Reference is made to "Redemption of Shares" in the Prospectus for certain
information as to the redemption and repurchase of Fund shares.
   
  The right to redeem shares or to receive payment with respect to any such
redemption may be suspended only for any period during which trading on the New
York Stock Exchange ("NYSE") is restricted as determined by the Securities and
Exchange Commission or such Exchange is closed (other than customary     
 
                                       8
<PAGE>
 
weekend and holiday closings), for any period during which an emergency exists
as defined by the Securities and Exchange Commission as a result of which
disposal of portfolio securities or determination of the net asset value of a
Fund is not reasonably practicable, and for such other periods as the
Securities and Exchange Commission may by order permit for the protection of
shareholders of the Fund.
 
  The value of shares at the time of redemption may be more or less than the
shareholder's cost, depending on the market value of the securities held by the
Fund and the Series at that time.
 
  Shares are redeemable at the option of the Corporation if, in the opinion of
the Corporation, ownership of the shares has or may become concentrated to the
extent which would cause the Corporation or a Fund to be deemed a personal
holding company within the meaning of the Code.
 
                      PORTFOLIO TRANSACTIONS AND BROKERAGE
   
  Because the Funds will invest exclusively in shares of their corresponding
Series it is expected that all transactions in portfolio securities will be
entered into by the Series. The Manager is responsible for making the Series'
portfolio decisions, placing the Series' brokerage business, evaluating the
reasonableness of brokerage commissions and negotiating the amount of any
commissions paid subject to a policy established by the Trust's Trustees and
officers. The Trust has no obligation to deal with any broker or group of
brokers in the execution of transactions in portfolio securities. Orders for
transactions in portfolio securities are placed for the Trust with a number of
brokers and dealers, including Merrill Lynch. In placing orders, it is the
policy of the Trust to obtain the most favorable net results, taking into
account various factors, including price, commissions, if any, size of the
transaction and difficulty of execution. Where practicable, the Manager surveys
a number of brokers and dealers in connection with proposed portfolio
transactions and selects the broker or dealer which offers the Trust the best
price and execution or other services which are of benefit to the Trust.
Securities firms also may receive brokerage commissions on transactions
including covered call options written by the Trust and the sale of underlying
securities upon the exercise of such options. In addition, consistent with the
Conduct Rules of the National Association of Securities Dealers, Inc. and
policies established by the Trustees, the Manager may consider sales of shares
of the Funds as a factor in the selection of brokers or dealers to execute
portfolio transactions for the Trust.     
   
  The Trust does not use any particular broker or dealer, and brokers who
provide supplemental investment research to the Manager may receive orders for
transactions by the Trust. Such supplemental research services ordinarily
consist of: quantitative and modeling information, assessments and analyses of
the business or prospects of a company, industry or economic sector.
Information so received will be in addition to and not in lieu of the services
required to be performed by the Manager under the Management Agreement. If in
the judgment of the Manager the Trust will be benefited by supplemental
research services, the Manager is authorized to pay brokerage commissions to a
broker furnishing such services which are in excess of commissions which
another broker may have charged for effecting the same transaction. The
expenses of the Manager will not necessarily be reduced as a result of the
receipt of such supplemental information, and the Manager may use such
information in servicing its other accounts. For the period April 3, 1997 to
June 30, 1997, the Series did not acquire any securities of brokers or dealers
which executed its portfolio transactions during that period.     
 
  The Trust anticipates that brokerage transactions involving securities of
companies domiciled in countries other than the United States will be conducted
primarily on the principal stock exchanges of such countries. Brokerage
commissions and other transaction costs on foreign stock exchange transactions
are
 
                                       9
<PAGE>
 
generally higher than in the United States, although the Trust will endeavor to
achieve the best net results in effecting its portfolio transactions. There is
generally less government supervision and regulation of foreign stock exchanges
and brokers than in the United States.
   
  The Trust invests in certain securities traded in the over-the-counter market
and, where possible, deals directly with the dealers who make a market in the
securities involved, except in those circumstances in which better prices and
execution are available elsewhere. Under the Investment Company Act, persons
affiliated with the Trust are prohibited from dealing with the Trust as
principal in purchase and sale of securities. Since transactions in the over-
the-counter ("OTC") market usually involve transactions with dealers acting as
principal for their own accounts, affiliated persons of the Trust, including
Merrill Lynch, will not serve as the Trust's dealer in such transactions.
However, affiliated persons of the Trust may serve as its broker in the OTC
transactions conducted on an agency basis.     
 
  Pursuant to Section 11(a) of the Securities Exchange Act of 1934, as amended,
Merrill Lynch may execute transactions for the Trust on the floor of any
national securities exchange provided that prior authorization of such
transactions is obtained and Merrill Lynch furnishes a statement to the Trust
at least annually setting forth the compensation it has received in connection
with such transactions.
   
  For the period April 3, 1997 (commencement of operations) to June 30, 1997,
the Funds paid brokerage commissions of $61,753 and $0 for the S&P 500 Index
Fund and the Aggregate Bond Index Fund, respectively. For the period April 9,
1997 (commencement of operations) to June 30, 1997, the Funds paid brokerage
commissions of $12,260 and $113,185 for the Small Cap Index Fund and the
International Index Fund, respectively. The Funds paid no commissions to
Merrill Lynch. The Trustees have considered the possibility of seeking to
recapture for the benefit of the Trust brokerage commissions, dealer spreads
and other expenses of possible portfolio transactions, such as underwriting
commissions, by conducting such portfolio transactions through affiliated
entities, including Merrill Lynch. For example, brokerage commissions received
by Merrill Lynch could be offset against the management fee paid by the Trust
to the Manager. After considering all factors deemed relevant, the Trustees
made a determination not to seek such recapture. The Trustees will reconsider
this matter from time to time.     
   
  Portfolio Turnover. Although the Series will use a passive, indexing approach
to investing, each Series may engage in a substantial number of portfolio
transactions. The rate of portfolio turnover will be a limiting factor when the
Manager considers whether to purchase or sell securities for a Series only to
the extent that the Manager will consider the impact of transaction costs on a
Series' tracking error. Changes in the securities comprising a Series' index
will tend to increase that Series' portfolio turnover rate, as the Manager
restructures the Series' holdings to reflect the changes in the index. A high
rate of portfolio turnover would result in correspondingly greater brokerage
commission expenses. Portfolio turnover rate is calculated by dividing the
lesser of the Series' annual sales or purchases of portfolio securities
(exclusive of purchases and sales of Government securities and of all other
securities, including options, whose maturity or expiration dates at the time
of acquisition were one year or less) by the monthly average value of the
securities in the Series during the fiscal year. For the period April 3, 1997
(commencement of operations) to June 30, 1997, the portfolio turnover of the
S&P 500 Index Series and the Aggregate Bond Index Series was 1.39% and 62.75%,
respectively. For the period April 9, 1997 (commencement of operations) to June
30, 1997, the portfolio turnover of the Small Cap Index Series and the
International Index Series was 26.02% and 5.45%, respectively.     
 
                                       10
<PAGE>
 
                        DETERMINATION OF NET ASSET VALUE
 
  Reference is made to "Additional Information--Determination of Net Asset
Value" in the Prospectus concerning the determination of net asset value.
   
  The net asset value of the shares of the Funds is determined once daily
Monday through Friday as of 15 minutes after the close of business on the NYSE
(generally 4:00 p.m., New York time) on each day the NYSE is open for trading
(a "Pricing Day"). The NYSE is not open for trading on New Year's Day,
Presidents' Day, Martin Luther King, Jr. Day, Good Friday, Memorial Day,
Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The net asset
value is computed by dividing the value of the securities held by a Fund plus
any cash or other assets (including interest and dividends accrued but not yet
received) minus all liabilities (including accrued expenses) by the total
number of shares outstanding at such time. Expenses, including the fees payable
to the Administrator and the Distributor, and the advisory fees payable
indirectly by the Series of the Trust to the Manager, are accrued daily.     
   
  The principal assets of each Fund will normally be its interest of the
underlying Series, which will be valued at its net asset value. A Series'
securities that are traded on stock exchanges are valued at the last sale price
as of the close of business on the day the securities are being valued, or,
lacking any sales, at the closing bid price. In cases where securities are
traded on more than one exchange, the securities are valued on the exchange
designated by or under the authority of the Board of Directors as the primary
market. Securities traded in the OTC market are valued at the last quoted bid
prices as at the close of trading on the NYSE on each day by brokers that make
markets in the securities. Securities traded on the NASDAQ national market
system are valued at the last sale price prior to the time of valuation. Other
investments, including futures contracts and related options, are stated at
market value. Securities and assets for which market quotations are not readily
available are valued at fair market value, as determined in good faith by or
under the direction of the Trustees of the Trust.     
   
  Each investor in the Trust may add to or reduce its investment in any Series
on each Pricing Day. The value of each investor's (including the respective
Funds') interest in a Series will be determined as of 15 minutes after the
close of business on the NYSE (generally 4:00 p.m., New York Time) by
multiplying the net asset value of the Series by the percentage, effective for
that day, that represents that investor's share of the aggregate interests in
such Series. Any additions or withdrawals, which are to be effected on that
day, will then be effected. The investor's percentage of the aggregate
beneficial interests in a Series will then be re-computed as the percentage
equal to the fraction (i) the numerator of which is the value of such
investor's investment in the Series as of the time or determination on such day
plus or minus, as the case may be, the amount of any additions to or
withdrawals from the investor's investment in the Series effected on such day,
and (ii) the denominator of which is the aggregate net asset value of the
Series as of such time on such day plus or minus, as the case may be, the
amount of the net additions to or withdrawals from the aggregate investments in
the Series by all investors in the Series. The percentage so determined will
then be applied to determine the value of the investor's interest in such
Series as of 15 minutes after the close of business of the NYSE on the next
Pricing Day of the Series.

                              SHAREHOLDER SERVICES
 
  The Funds offer a number of shareholder services described below which are
designed to facilitate investment in their shares. Full details as to each of
such services and copies of the various plans described below can be obtained
from the Funds, the Distributor or Merrill Lynch. Certain of these services are
available only to United States investors.
 
INVESTMENT ACCOUNT
 
  Each shareholder whose account is maintained at the Transfer Agent has an
Investment Account and will receive statements, at least quarterly, from the
Transfer Agent. These statements will serve as transaction confirmations for
automatic investment purchases and the reinvestment of ordinary income
dividends and long-term capital gains distributions. The statement will also
show any other activity in the account since the preceding statements.
Shareholders will receive separate transaction confirmations for each purchase
or sale transaction other than automatic investment purchase and the
reinvestment of ordinary income dividends and long-term capital gains
distribution. Shareholders may make additions to their Investment Account at
any time by mailing a check directly to the Transfer Agents. Shareholders may
also maintain their accounts through Merrill Lynch. Upon the transfer of shares
out of a Merrill Lynch brokerage account, an Investment Account in the
transferring shareholder's name will be opened automatically, without charge,
at the Transfer Agent. Shareholders interested in transferring their shares
from Merrill Lynch and who do not wish to have an Investment Account maintained
for such shares at the Transfer Agent may request their new brokerage firm to
maintain such shares in an account registered in the name of the brokerage firm
for the benefit of the shareholder. If the new brokerage firm is willing to
accommodate the shareholder in this manner, the shareholder must request that
he be issued certificates for his shares, and then must turn the certificates
over to the new firm for re-registration as described in the preceding
sentence. Shareholders considering transferring from Merrill Lynch to another
brokerage firm or financial institution should be aware that, if the firm to
which the account is to be transferred will not take delivery of shares of a
Fund, a shareholder must either redeem the shares so that the cash proceeds can
be transferred to the account at the new firm, or such shareholder must
continue to maintain an account at Merrill Lynch for those shares.
 
  Share certificates are issued only for full shares and only upon the specific
request of the shareholder. Issuance of certificates representing all or only
part of the full shares of an Investment Account may be requested by a
shareholder directly from Merrill Lynch Financial Data Services, Inc. (the
"Transfer Agent").
 
AUTOMATIC REINVESTMENT OF DIVIDENDS AND CAPITAL GAINS DISTRIBUTIONS
 
  Unless specific instructions are given as to the method of payment of
dividends and capital gains distributions, dividends and distributions will be
reinvested automatically in additional shares of the Funds. Such reinvestment
will be at the net asset value of shares of a Fund, without sales charge, as of
the close of business on the ex-dividend date of the dividend or distribution.
Shareholders may elect in writing or by telephoning (1-800-MER-FUND) to receive
either their income dividends or capital gains distributions, or both, in cash,
in which event payment will be mailed on or about the payment date.
Shareholders may, at any time, notify the Transfer Agent in writing that they
no longer wish to have their dividends and/or distributions reinvested in
shares of the Fund or vice versa and, commencing ten days after the receipt by
the Transfer Agent of such notice, those instructions will be effected.
 
                                       12
<PAGE>
 
SYSTEMATIC WITHDRAWAL PLANS
   
  A shareholder may elect to receive systematic withdrawal payments from such
shareholder's Investment Account in the form of payments by check or through
automatic payment by direct deposit to such shareholder's bank account on
either a monthly or quarterly basis. Shareholders whose shares are held within
a CMA(R), CBA(R) or Retirement Account may elect to have shares redeemed on a
monthly, bi-monthly, quarterly, semiannual or annual basis through the
CMA(R)/CBA(R) Systematic Redemption Program, subject to certain conditions.
    
AUTOMATIC INVESTMENT PLANS
 
  Regular additions of shares may be made in an investor's Investment Account
by prearranged charges of $50 or more to such investor's regular bank account.
Investors who maintain CMA(R) accounts may arrange to have periodic investments
made in the Funds in their CMA(R) account or in certain related accounts in
amounts of $100 or more through the CMA(R) Automated Investment Program.
 
RETIREMENT PLANS
 
  Self-directed individual retirement accounts and other retirement plans are
available from Merrill Lynch. Under these plans, investments may be made in a
Fund and certain of the other mutual funds sponsored by Merrill Lynch as well
as in other securities. Merrill Lynch charges an initial establishment fee and
an annual custodial fee for each account. Information with respect to these
plans is available on request from Merrill Lynch. The minimum initial purchase
to establish any such plan is $100 and the minimum subsequent purchase is $1.
 
  Capital gains and income received in each of the plans referred to above are
exempt from Federal taxation until distributed from the plans. Investors
considering participation in any such plan should review specific tax laws
relating thereto and should consult their attorneys or tax advisers with
respect to the establishment and maintenance of any such plan.
 
                       DIVIDENDS, DISTRIBUTIONS AND TAXES
 
DIVIDENDS AND DISTRIBUTIONS
   
  It is the Corporation's intention to distribute all of its net investment
income, if any. Dividends from such net investment income are paid at least
annually with respect to each of the S&P 500 Index Fund, Small Cap Index Fund
and International Index Fund. Dividends with respect to the Aggregate Bond
Index Fund are declared daily and paid monthly. All net realized long-, mid- or
short-term capital gains, if any, are distributed to Fund shareholders at least
annually. From time to time, a Fund may declare a special distribution at or
about the end of the calendar year in order to comply with a Federal income tax
requirement that certain percentages of its ordinary income and capital gains
be distributed during the taxable year. See "Shareholder Services--Reinvestment
of Dividends and Capital Gains Distributions" for information concerning the
manner in which dividends and distributions may be reinvested automatically in
shares of the Funds. Shareholders may elect in writing to receive any such
dividends or distributions, or both, in cash.     
 
TAXES
   
  The Funds intend to continue to qualify for the special tax treatment
afforded regulated investment companies ("RICs") under the Internal Revenue
Code of 1986, as amended (the "Code"). As a RIC, a Fund     
 
                                       13
<PAGE>
 
   
will not be subject to Federal income tax on the part of its net ordinary
income and net realized capital gains which it distributes to shareholders. In
order to qualify, the Fund generally must among other things, (i) derive at
least 90% of its gross income from dividends, interest, payments with respect
to certain securities loans, gains from the sale of securities, or other income
(including but not limited to gains from options or futures) derived with
respect to its business of investing in such stock or securities; (ii) with
respect to tax years beginning before August 5, 1997 derive less than 30% of
its gross income from gains from the sale or other disposition of stock,
securities, options or futures held for less than 3 months; (iii) distribute at
least 90% of its dividend, interest and certain other taxable income each year;
(iv) at the end of each fiscal quarter maintain at least 50% of the value of
its total assets in cash, government securities, securities of other RICs, and
other securities of issuers which represent, with respect to each issuer, no
more than 5% of the value of the Fund's total assets and 10% of the outstanding
voting securities of such issuer; and (v) at the end of each fiscal quarter
have no more than 25% of its assets invested in the securities (other than
those of the government or other RICs) of any one issuer or of two or more
issuers which the Fund controls and which are engaged in the same, similar or
related trades and businesses.     
   
  Dividends paid by a Fund from its ordinary income and distributions of the
Fund's net realized short-term capital gains (together referred to hereafter as
"ordinary income dividends") are taxable to shareholders as ordinary income.
Distributions made from a Fund's net realized mid- or long-term capital gains
(including long-term gains from certain transactions in futures and options)
are taxable to shareholders as mid- or long-term capital gains, regardless of
the length of time the shareholder has owned Fund shares. Any loss upon the
sale or exchange of Fund shares held for six months or less, however, will be
treated as long-term capital loss to the extent of any capital gains
distributions received by the shareholder with respect to such shares.
Distributions in excess of a Fund's earnings and profits will first reduce the
adjusted tax basis of a holder's shares and, after such adjusted tax basis is
reduced to zero, will constitute capital gains to such holder (assuming the
shares are held as a capital asset).     
 
  Dividends and distributions are taxable to shareholders even though they are
reinvested in additional shares of a Fund. Not later than 60 days after the
close of its taxable year, the Funds will provide shareholders with a written
notice designating the amounts of any ordinary income dividends or capital
gains dividends. A portion of the ordinary income dividends paid by the S&P 500
Index Fund and Small Cap Index Fund may be eligible for the 70% dividends
received deduction allowed to corporations under the Code, if certain
requirements are met. For this purpose, the Funds will allocate dividends
eligible for the dividends received deduction between the Class A and Class D
shareholders according to a method that is based upon the gross income that is
allocable to the Class A and Class D shareholders during the taxable year, or
such other method as the Internal Revenue Service may prescribe. Distributions
paid by the Aggregate Bond Index Fund and the International Index Fund will not
be eligible for the dividends received deduction. If a Fund pays a dividend in
January which was declared in the previous October, November or December to
shareholders of record on a specified date in one of such months, then such
dividend will be treated for tax purposes as being paid by the Fund and
received by its shareholders on December 31 of the year in which such dividend
was declared.
 
  Redemptions and exchanges of a Fund's shares are taxable events, and,
accordingly, shareholders may realize gains or losses on such events. A loss
realized on a sale or exchange of shares of a Fund will be disallowed if other
Fund shares are acquired (whether through the automatic reinvestment of
dividends or otherwise) within a 61-day period beginning 30 days before and
ending 30 days after the date that the shares are disposed of. In such a case,
the basis of the shares acquired will be adjusted to reflect the disallowed
loss.
 
                                       14
<PAGE>
 
  Ordinary income dividends paid by a Fund to shareholders who are nonresident
aliens or foreign entities generally will be subject to a 30% United States
withholding tax under existing provisions of the Code applicable to foreign
individuals and entities unless a reduced rate of withholding or a withholding
exemption is provided under the applicable treaty law. Nonresident shareholders
are urged to consult their own tax advisers concerning the applicability of the
United States withholding tax.
   
  Dividends and interest received by the International Index Fund and the
Aggregate Bond Index Fund may give rise to withholding and other taxes imposed
by foreign countries. Tax conventions between certain countries and the United
States may reduce or eliminate such taxes. Shareholders of the International
Index Fund may be able to claim U.S. foreign tax credits with respect to such
taxes, subject to certain provisions and limitations contained in the Code. For
example, certain retirement accounts cannot claim foreign tax credits on
investments in foreign securities held by the Fund. The International Index
Fund expects to be eligible, and intends, to file an election with the Internal
Revenue Service pursuant to which shareholders of the Fund will be required to
include their proportionate share of such withholding taxes in their U.S.
income tax returns as gross income, treat such proportionate share as taxes
paid by them, and deduct such proportionate share in computing their taxable
incomes or, alternatively, subject to certain restrictions, use them as foreign
tax credits against their U.S. income taxes. No deductions for foreign taxes,
however, may be claimed by noncorporation shareholders who do not itemize
deductions. A shareholder that is a nonresident alien individual or a foreign
corporation may be subject to U.S. withholding tax on the income resulting from
the Fund's election described in this paragraph but may not be able to claim a
credit or deduction against such U.S. tax for the foreign taxes treated as
having been paid by such shareholder. The International Equity Fund will report
annually to its shareholders the amount per share of such withholding taxes.
For this purpose, the Fund will allocate foreign taxes and foreign source
income among the Class A and Class D shareholders according to a method similar
to that described above for the allocation of dividends eligible for the
dividends received deduction.     
 
  The Code requires a RIC to pay a nondeductible 4% excise tax to the extent
the RIC does not distribute, during each calendar year, 98% of its ordinary
income, determined on a calendar basis, and 98% of its capital gains,
determined, in general, on an October 31 year end, plus certain undistributed
amounts from previous years. For purposes of determining its distribution
requirements, each Fund will account for its share of items of income, gain,
loss and deductions of the Series as they are taken into account by the Series.
While each Fund intends to distribute its income and capital gains in the
manner necessary to avoid imposition of the 4% excise tax, there can be no
assurance that sufficient amounts of the Fund's taxable income and capital
gains will be distributed to avoid entirely the imposition of the tax. In such
event, the Fund will be liable for the tax only on the amount by which it does
not meet the foregoing distribution requirements.
 
  Under certain provisions of the Code, some shareholders may be subject to a
31% withholding tax on reportable dividends, capital gains distributions and
redemption payments ("backup withholding"). Generally, shareholders subject to
backup withholding will be those for whom a certified taxpayer identification
number is not on file with the Corporation or who, to the Corporation's
knowledge, have furnished an incorrect number. When establishing an account, an
investor must certify under penalty of perjury that such number is correct and
that such investor is not otherwise subject to backup withholding.
 
TAX TREATMENT OF OPTIONS AND FUTURES TRANSACTIONS
 
  Each Fund may purchase or sell options and futures. Options and futures
contracts that are "Section 1256 contracts" will be "marked to market" for
Federal income tax purposes at the end of each taxable year,
 
                                       15
<PAGE>
 
i.e., each such option or futures contract will be treated as sold for its fair
market value on the last day of the taxable year. In general, unless the
special election referred to in the previous sentence is made, gain or loss
from Section 1256 contracts will be 60% long-term and 40% short-term capital
gain or loss. The mark-to-market rules outlined above, however, will not apply
to certain transactions entered into by a Fund solely to reduce the risk of
changes in price or interest rates with respect to its investments.
   
  Newly-enacted Code Section 1259 will require the recognition of gain (but not
loss) if a Fund makes a "constructive sale" of an appreciated financial
position (e.g. debt instruments and stocks). A Fund generally will be
considered to make a constructive sale of an appreciated financial position if
it sells the same or substantially identical property short, enters into a
futures or forward contract to deliver the same or substantially identical
property, or enters into certain other similar transactions.     
   
  Code Section 1092, which applies to certain "straddles," may affect the
taxation of each Fund's transactions in options and futures contracts. Under
Section 1092, a Fund may be required to postpone recognition for tax purposes
of losses incurred in certain closing transactions in options and futures.
Similarly, Code Section 1091, which deals with "wash sales," may cause a Fund
to postpone recognition of certain losses for tax purposes; and Code Section
1258, which deals with "conversion transactions," may apply to recharacterize
certain capital gains as ordinary income for tax purposes.     
   
  One of the requirements for qualification as a RIC (which applies only to tax
years beginning before August 5, 1997) is that less than 30% of a Fund's gross
income may be derived from gains from the sale or other disposition of
securities held for less than three months. Accordingly, the Funds may be
restricted in effecting closing transactions within three months after entering
into an options or futures contract.     
 
SPECIAL RULES FOR CERTAIN FOREIGN CURRENCY TRANSACTIONS
 
  In general, gains from "foreign currencies" and from foreign currency
options, foreign currency futures and forward foreign exchange contracts
relating to investments in stock, securities or foreign currencies will be
qualifying income for purposes of determining whether a Series qualifies as a
RIC. It is currently unclear, however, who will be treated as the issuer of a
foreign currency instrument or how foreign currency options, foreign currency
futures and forward foreign exchange contracts will be valued for purposes of
the RIC diversification requirements applicable to a Series.
 
  Under Code Section 988, special rules are provided for certain transactions
in a foreign currency other than the taxpayer's functional currency (i.e.,
unless certain special rules apply, currencies other than the United States
dollar). In general, foreign currency gains or losses from certain forward
contracts, from futures contracts that are not "regulated futures contracts"
and from unlisted options will be treated as ordinary income or loss under Code
Section 988. In certain circumstances, a Series may elect capital gain or loss
treatment for such transactions. In general, however, Code Section 988 gains or
losses will increase or decrease the amount of a Fund's investment company
taxable income available to be distributed to shareholders as ordinary income,
rather than increasing or decreasing the amount of the Fund's net capital
gains. Additionally, if Code Section 988 losses exceed other investment company
taxable income during a taxable year, the Fund would not be able to make any
ordinary dividend distributions, and any distributions made before the losses
were realized but in the same taxable year would be recharacterized as a return
of capital to shareholders, thereby reducing the basis of each shareholder's
Fund shares.
 
                                       16
<PAGE>
 
THE SERIES
 
  The Trust and each Fund have received a private letter ruling from the
Internal Revenue Service ("IRS"), in which the IRS has ruled that each Series
is classified as a partnership for tax purposes and, based upon that ruling,
that each Fund will be entitled to look to the underlying assets of the Series
in which it has invested for purposes of satisfying the diversification
requirements and other requirements of the Code applicable to RICs. If any of
the facts upon which such ruling is premised change in any material respect
(e.g., if the Trust were required to register its interests under the
Securities Act) and the Trust is unable to obtain a revised private letter
ruling from the IRS indicating that each Series will continue to be classified
as a partnership, then the Board of Directors of the Corporation will
determine, in its discretion, the appropriate course of action for the Funds.
One possible course of action would be to withdraw the Funds' investments from
the Series and to retain an investment adviser to manage the Funds' assets in
accordance with the investment policies applicable to the respective Fund. See
"Investment Objectives and Policies."
   
  The foregoing is a general and abbreviated summary of the applicable
provisions of the Code and Treasury regulations presently in effect, and does
not address the state and local tax, or estate or inheritance tax, consequences
of an investment in a Fund. For the complete provisions, reference should be
made to the pertinent Code sections and the Treasury regulations promulgated
thereunder. The Code and the Treasury regulations are subject to change by
legislative or administrative action either prospectively or retroactively.
    
  Dividends and capital gains distributions and gain on the sale or exchange of
shares in a Fund may also be subject to state and local taxes.
 
  Shareholders are urged to consult their own tax advisers regarding specific
questions as to Federal, state, local or foreign taxes or estate or inheritance
tax. Foreign investors should consider applicable foreign taxes in their
evaluation of an investment in a Fund.
 
                                PERFORMANCE DATA
 
  From time to time a Fund may include its Fund's average annual total return,
other total return data and/or yield in advertisements or information furnished
to present or prospective shareholders. Total return figures are based on a
Fund's historical performance and are not intended to indicate future
performance. Average annual total return and yield are determined in accordance
with a formula specified by the Securities and Exchange Commission.
 
  Average annual total return quotations for the specified periods are computed
by finding the average annual compounded rates of return (based on net
investment income and any realized and unrealized capital gains or losses on
portfolio investments over such periods) that would equate the initial amount
invested to the redeemable value of such investment at the end of each period.
Average annual total return is computed assuming all dividends and
distributions are reinvested and taking into account all applicable recurring
and nonrecurring expenses.
 
  Each Fund also may quote annual, average annual and annualized total return
and aggregate total return performance data, both as a percentage and as a
dollar amount based on a hypothetical $1,000 investment. Such data will be
computed as described above, except that as required by the periods of the
quotations, actual annual, annualized or aggregate data, rather than average
annual data, may be quoted. Actual annual or annualized total return data
generally will be lower than average annual total return data since the average
rates of return reflect compounding of return; aggregate total return data
generally will be higher than average annual total return data since the
aggregate rates of return reflect compounding over a longer period of time.
 
 
                                       17
<PAGE>
 
   
  Yield quotations will be computed based on a 30-day period by dividing (a),
the net income based on the yield of each security earned during the period by
(b), the average number of shares outstanding during the period that were
entitled to receive dividends, multiplied by the maximum offering price per
share on the last day of the period.     
 
  From time to time, a Fund may include its Fund's Morningstar risk-adjusted
performance ratings in advertisements or supplemental sales literature.
   
  Set forth below is total return and yield information for the Class A and
Class D shares of the Funds for the periods indicated.

                              GENERAL INFORMATION
 
DESCRIPTION OF SHARES
   
  The Corporation is a Maryland corporation incorporated on October 25, 1996.
It has an authorized capital of 1,000,000,000 shares of Common Stock, par value
$0.0001 per share, divided into 125,000,000 shares each of Class A and Class D
shares for each of the four Funds: S&P 500 Index Fund, Small Cap Index Fund,
Aggregate Bond Index Fund and International Index Fund. Class A and Class D
shares of a Fund represent interests in the same assets of the Series and are
identical in all respects except that the Class D shares bear certain expenses
related to the account maintenance associated with such shares. Class D shares
have exclusive voting rights with respect to matters relating to the class'
account maintenance expenditures.     
 
  Shareholders are entitled to one vote for each full share held and to
fractional votes for fractional shares held in the election of Directors (to
the extent hereafter provided) and on other matters submitted to the vote of
shareholders. All shares of each Fund have equal voting rights, except that
each Fund has exclusive voting rights to matters affecting only such Fund, and
except that as noted above, Class D shares have exclusive voting rights with
respect to matters relating to the class' account maintenance expenditures.
There normally will be no meeting of shareholders for the purpose of electing
Directors unless and until such time as less than a majority of the Directors
holding office have been elected by the shareholders, at which time the
Directors then in office will call a shareholders' meeting for the election of
Directors. Shareholders may, in accordance with the terms of the Articles of
Incorporation, cause a meeting of shareholders to be held for the purpose of
voting on the removal of Directors. Also, the Corporation will be required to
call a special meeting of shareholders in accordance with the requirements of
the Investment Company Act to seek approval of new management and advisory
arrangements, of a material increase in account maintenance fees or of a change
in fundamental policies, objectives or restrictions. Except as set forth above,
the Directors shall continue to hold office and appoint successor Directors.
Each issued and outstanding share is entitled to participate equally in
dividends and distributions declared and in net assets upon liquidation or
dissolution remaining after satisfaction of outstanding liabilities, except
that, as noted above, Class D shares bear certain additional expenses. Shares
issued are fully-paid and non-assessable by the Fund. Voting rights for
Directors are not cumulative.
 
  Stock certificates are issued by the Transfer Agent only on specific request.
Certificates for fractional shares are not issued in any case.
 
  The Trust consists of four Series, and is organized as a Delaware business
trust. Whenever a Fund is requested to vote on a fundamental policy of a
Series, the Corporation will hold a meeting of the investing Fund's
shareholders and will cast its vote as instructed by such Fund's shareholders.
   
  MLAM provided the initial capital for each Fund by purchasing 2,500 Class A
shares of each Fund (10,000 total) and 2,500 Class D shares of each Fund
(10,000 total), for an aggregate of $50,000 per Fund. Such shares were acquired
for investment and can only be disposed of by redemption. The organizational
expenses of the Corporation were paid by the Corporation and are amortized over
a period not exceeding five years. The proceeds realized by MLAM upon
redemption of any of such shares will be reduced by the proportionate amount of
the unamortized organizational expenses which the number of shares redeemed
bears to the number of shares initially purchased.

NOTES TO FINANCIAL STATEMENTS


MERRILL LYNCH
S&P 500
INDEX FUND

1. Significant Accounting Policies: Merrill Lynch S&P 500 Index Fund (the
"Fund") is part of Merrill Lynch Index Funds, Inc. The Fund is registered under
the Investment Company Act of 1940 as a non-diversified mutual fund. The Fund
seeks to achieve its investment objective by investing all of its assets in the
Merrill Lynch S&P 500 Index Series (the "Series") of the Merrill Lynch Index
Trust, which has the same investment objective as the Fund. The value of the
Fund's investment in the Series reflects the Fund's proportionate interest in
the net assets of the Series. The performance of the Fund is directly affected
by


                                      28
<PAGE>
 
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. These unaudited
financial statements reflect all adjustments which are, in the opinion of
management, necessary to a fair statement of the results for the interim period
presented. All such adjustments are of a normal recurring nature. The Fund
offers two classes of shares, Class A Shares and Class D Shares. Shares of Class
A and Class D are sold without the imposition of a front-end or deferred sales
charge. Both classes of shares have identical voting, dividend, liquidation and
other rights and the same terms and conditions, except that Class D Shares bear
certain expenses related to the account maintenance of such shares. The
following is a summary of significant accounting policies followed by the Fund.

(a) Valuation of investments--Valuation of securities is discussed
in Note 1a of the Series' Notes to Financial Statements which is
included elsewhere in this report.

(b) Income--The Fund's net investment income consists of the Fund's
pro rata share of the net investment income of the Series, less all
actual and accrued expenses of the Fund determined in accordance
with generally accepted accounting principles.

(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 all of its taxable income to
shareholders. Therefore, no Federal income tax provision is
required.

(d) Prepaid registration fees and deferred organization expenses--
Prepaid registration fees are charged to expense as the related
shares are issued. Deferred organization expenses are charged to
expense on a straight-line basis over a five-year period.

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

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


2. Transactions with Affiliates:
The Fund has entered into a Distribution Agreement and Distribution
Plans with Merrill Lynch Funds Distributor, Inc. ("MLFD" or
"Distributor"), a wholly-owned subsidiary of Merrill Lynch Group,
Inc. Pursuant to a distribution plan (the "Distribution Plan")
adopted by the Fund 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 0.25% based upon the average
daily net assets of Class D Shares.

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

The Fund has also entered into an Administrative Services Agreement
with Merrill Lynch Asset Management, L.P. ("MLAM"). The general
partner of MLAM is Princeton Services, Inc. ("PSI"), a wholly-owned
subsidiary of ML & Co., which is the limited partner. The Fund pays
a monthly fee at an annual rate of 0.20% of the Fund's average daily
net assets for the performance of administrative services (other
than investment advice and related portfolio activities) necessary
for the operation of the Fund. For the period April 3, 1997 to June
30, 1997, MLAM earned fees of $94,046, of which $47,980 was
voluntarily waived.

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

Accounting services are provided to the Fund by MLAM at cost.

Certain officers and/or directors of the Fund are officers and/or
directors of MLAM, PSI, MLFD, MLFDS, and/or ML & Co.

Merrill Lynch S&P 500 Index Fund, June 30, 1997

NOTES TO FINANCIAL STATEMENTS

MERRILL LYNCH
S&P 500
INDEX SERIES

1. Significant Accounting Policies:
Merrill Lynch S&P 500 Index Series (the "Series") is part of Merrill
Lynch Index Trust (the "Trust"). The Trust is registered under the
Investment Company Act of 1940 and is organized as a Delaware
business trust. These unaudited financial statements reflect all
adjustments which are, in the opinion of management, necessary to a
fair statement of the results for the interim period presented. All
such adjustments are of a normal recurring nature. The following is
a summary of significant accounting policies followed by the Series.

(a) Valuation of investments--Portfolio securities which are traded
on stock exchanges are valued at the last sale price as of the close
of business on the day the securities are being valued or, lacking
any sales, at the closing bid price. Securities traded in the over-
the-counter market are valued at the last quoted bid price at the
close of trading on the New York Stock Exchange on each day by
brokers that make markets in the securities. Securities traded in
the NASDAQ National Market System are valued at the last sale price
prior to the time of valuation. Portfolio securities which are
traded both on the over-the-counter 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
over-the-counter market, the last asked price. Options purchased are
valued at the last sale price in the case of exchange-traded options
or, in the case of options traded in the over-the-counter market,
the last bid price. Other investments, including futures contracts
and related options, are stated at market value. Short-term
securities are valued at amortized cost, which approximates market
value. Securities and assets for which market quotations are not
readily available are valued at fair market value, as determined in
good faith by or under the direction of the Trust's Board of
Trustees.

(b) Derivative financial instruments--The Series may engage in
various portfolio investment techniques to provide liquidity, or in
connection with the Series' arbitrage strategies. Losses may arise
due to changes in the value of the contract or if the counterparty
does not perform under the contract.

* Financial futures contracts--The Series may purchase or sell stock
index futures contracts and options on such futures contracts as a
proxy for a direct investment in securities underlying the Series'
index. Upon entering into a contract, the Series deposits and
maintains as collateral such initial margin as required by the
exchange on which the transaction is effected. Pursuant to the
contract, the Series agrees to receive from or pay to the broker an
amount of cash equal to the daily fluctuation in value of the
contract. Such receipts or payments are known as variation margin
and are recorded by the Series as unrealized gains or losses. When
the contract is closed, the Series records a realized gain or loss
equal to the difference between the value of the contract at the
time it was opened and the value at the time it was closed.

* Options--The Series is authorized to purchase and write call and
put options. When the Series writes an option, an amount equal to
the premium received by the Series is reflected as an asset and an
equivalent liability. The amount of the liability is subsequently
marked to market to reflect the current market value of the option
written. When a security is purchased or sold through an exercise of
an option, the related premium paid (or received) is added to (or
deducted from) the basis of the security acquired or deducted from
(or added to) the proceeds of the security sold. When an option
expires (or the Series enters into a closing transaction), the
Series realizes a gain or loss on the option to the extent of the
premiums received or paid (or a gain or loss to the extent that the
cost of the closing transaction exceeds the premium paid or
received).

Written and purchased options are non-income producing investments.

(c) Income taxes--The Series is classified as a partnership for
Federal income tax purposes. As a partnership for Federal income tax
purposes, the Series will not incur Federal income tax liability.
Items of partnership income, gain, loss and deduction will pass
through to investors as partners in the Series. Therefore, no
Federal income tax provision is required.

(d) Security transactions and investment income--Security
transactions are accounted for on the date the securities are
purchased or sold (the trade dates). Dividend income is recorded on
the ex-dividend dates. Interest income (including amortization of
discount) is recognized on the accrual basis. Realized gains and
losses on security transactions are determined on the identified
cost basis.

(e) Deferred organization expenses--Deferred organization expenses
are charged to expense on a straight-line basis over a five-year
period.

2. Investment Advisory Agreement and Transactions
with Affiliates:
The Series has entered into an Investment Advisory Agreement with
Merrill Lynch Asset Management, L.P. ("MLAM"). The general partner
of MLAM is Princeton Services, Inc. ("PSI"), an indirect wholly-
owned subsidiary of Merrill Lynch & Co., Inc. ("ML & Co."), which is
the limited partner.

MLAM is responsible for the management of the Fund's portfolio and
provides the necessary personnel, facilities, equipment and certain
other services necessary to the operations of the Fund. For such
services, the Series pays a monthly fee at an annual rate of 0.05%
of the average daily value of the Series' net assets. For the period
ended June 30, 1997, MLAM earned fees of $23,504, all of which was
voluntarily waived.

Accounting services are provided to the Series by MLAM at cost.

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


3. Investments:

for the period April 3, 1997 to June 30, 1997 were $228,929,113 and

As of June 30, 1997, net unrealized appreciation for Federal income
tax purposes aggregated $24,774,611, of which $25,929,392 related to
appreciated securities and $1,154,781 related to depreciated
securities. At June 30, 1997, the aggregate cost of investments for
Federal income tax purposes was $267,065,276.

NOTES TO FINANCIAL STATEMENTS


MERRILL LYNCH
SMALL CAP
INDEX FUND

1. Significant Accounting Policies:
Merrill Lynch Small Cap Index Fund (the "Fund") is part of Merrill
Lynch Index Funds, Inc. The Fund is registered under the Investment
Company Act of 1940 as a non-diversified mutual fund. The Fund seeks
to achieve its investment objective by investing all of its assets
in the Merrill Lynch Small Cap Index Series (the "Series") of the
Merrill Lynch Index Trust, which has the same investment objective
as the Fund. The value of the Fund's investment in the Series
reflects the Fund's proportionate interest in the net assets of the
Series. The performance of the Fund is directly affected by the
performance of the Series. The financial statements of the Series,
including the Schedule of Investments, are included elsewhere in
this report and should be read in conjunction with the Fund's
financial statements. These unaudited financial statements reflect
all adjustments which are, in the opinion of management, necessary
to a fair statement of the results for the interim period presented.
All such adjustments are of a normal recurring nature. The Fund
offers two classes of shares, Class A Shares and Class D Shares.
Shares of Class A and Class D are sold without the imposition of a
front-end or deferred sales charge. Both classes of shares have
identical voting, dividend, liquidation and other rights and the
same terms and conditions, except that Class D Shares bear certain
expenses related to the account maintenance of such shares. 


                                      46
<PAGE>
 
The following is a summary of significant accounting policies 
followed by the Fund.

(a) Valuation of investments--Valuation of securities is discussed
in Note 1a of the Series' Notes to Financial Statements which is
included elsewhere in this report.

(b) Income--The Fund's net investment income consists of the Fund's
pro rata share of the net investment income of the Series, less all
actual and accrued expenses of the Fund determined in accordance
with generally accepted accounting principles.

(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 all of its taxable income to
shareholders. Therefore, no Federal income tax provision is
required.

(d) Prepaid registration fees and deferred organization expenses--
Prepaid registration fees are charged to expense as the related
shares are issued. Deferred organization expenses are charged to
expense on a straight-line basis over a five-year period.

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

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

2. Transactions with Affiliates:
The Fund has entered into a Distribution Agreement and Distribution
Plans with Merrill Lynch Funds Distributor, Inc. ("MLFD" or
"Distributor"), a wholly-owned subsidiary of Merrill Lynch Group,
Inc. Pursuant to a distribution plan (the "Distribution Plan")
adopted by the Fund 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 0.25% based upon the average
daily net assets of Class D Shares.

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

The Fund has also entered into an Administrative Services Agreement
with Merrill Lynch Asset Management, L.P. ("MLAM"). The general
partner of MLAM is Princeton Services, Inc. ("PSI"), a wholly-owned
subsidiary of ML & Co., which is the limited partner. The Fund pays
a monthly fee at an annual rate of 0.22% of the Fund's average daily
net assets for the performance of administrative services (other
than investment advice and related portfolio activities) necessary
for the operation of the Fund. For the period April 9, 1997 to June
30, 1997, MLAM earned fees of $16,520, all of which were voluntarily
waived. MLAM also reimbursed the Fund for additional expenses of
$24,612.

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

Accounting services are provided to the Fund by MLAM at cost.

Certain officers and/or directors of the Fund are officers and/or
directors of MLAM, PSI, MLFD, MLFDS, and/or ML & Co.

under the Investment Company Act of 1940 and is organized as a
Delaware business trust. These unaudited financial statements
reflect all adjustments which are, in the opinion of management,
necessary to a fair statement of the results for the interim period
presented. All such adjustments are of a normal recurring nature.
The following is a summary of significant accounting policies
followed by the Series.

(a) Valuation of investments--Portfolio securities which are traded
on stock exchanges are valued at the last sale price as of the close
of business on the day the securities are being valued or, lacking
any sales, at the closing bid price. Securities traded in the over-
the-counter market are valued at the last quoted bid price at the
close of trading on the New York Stock Exchange on each day by
brokers that make markets in the securities. Securities traded in
the NASDAQ National Market System are valued at the last sale price
prior to the time of valuation. Portfolio securities which are
traded both on the over-the-counter 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
over-the-counter market, the last asked price. Options purchased are
valued at the last sale price in the case of exchange-traded options
or, in the case of options traded in the over-the-counter market,
the last bid price. Other investments, including futures contracts
and related options, are stated at market value. Short-term
securities are valued at amortized cost, which approximates market
value. Securities and assets for which market quotations are not
readily available are valued at fair market value, as determined in
good faith by or under the direction of the Trust's Board of
Trustees.

(b) Derivative financial instruments--The Series may engage in
various portfolio investment techniques to provide liquidity, or in
connection with the Series' arbitrage strategies. Losses may arise
due to changes in the value of the contract or if the counterparty
does not perform under the contract.

* Financial futures contracts--The Series may purchase or sell stock
index futures contracts and options on such futures contracts as a
proxy for a direct investment in securities underlying the Series'
index. Upon entering into a contract, the Series deposits and
maintains as collateral such initial margin as required by the
exchange on which the transaction is effected. Pursuant to the
contract, the Series agrees to receive from or pay to the broker an
amount of cash equal to the daily fluctuation in value of the
contract. Such receipts or payments are known as variation margin
and are recorded by the Series as unrealized gains or losses. When
the contract is closed, the Series records a realized gain or loss
equal to the difference between the value of the contract at the
time it was opened and the value at the time it was closed.

* Options--The Series is authorized to purchase and write call and
put options. When the Series writes an option, an amount equal to
the premium received by the Series is reflected as an asset and an
equivalent liability. The amount of the liability is subsequently
marked to market to reflect the current market value of the option
written. When a security is purchased or sold through an exercise of
an option, the related premium paid (or received) is added to (or
deducted from) the basis of the security acquired or deducted from
(or added to) the proceeds of the security sold. When an option
expires (or the Series enters into a closing transaction), the
Series realizes a gain or loss on the option to the extent of the
premiums received or paid (or a gain or loss to the extent that the
cost of the closing transaction exceeds the premium paid or
received).

Written and purchased options are non-income producing investments.

(c) Income taxes--The Series is classified as a partnership for
Federal income tax purposes. As a partnership for Federal income tax
purposes, the Series will not incur Federal income tax liability.
Items of partnership income, gain, loss and deduction will pass
through to investors as partners in the Series. Therefore, no
Federal income tax provision is required.

(d) Security transactions and investment income--Security trans-
actions are accounted for on the date the securities are purchased
or sold (the trade dates). Dividend income is recorded on the ex-
dividend dates. Interest income (including amortization of discount)
is recognized on the accrual basis. Realized gains and losses on
security transactions are determined on the identified cost basis.

(e) Deferred organization expenses--Deferred organization expenses
are charged to expense on a straight-line basis over a five-year
period.

2. Investment Advisory Agreement and Transactions
with Affiliates:
The Series has entered into an Investment Advisory Agreement with
Merrill Lynch Asset Management, L.P. ("MLAM"). The general partner
of MLAM is Princeton Services, Inc. ("PSI"), an indirect wholly-
owned subsidiary of Merrill Lynch & Co., Inc. ("ML & Co."), which is
the limited partner.

MLAM 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 0.08%
of the average daily value of the Series' net assets. For the period
April 9, 1997 to June 30, 1997, MLAM earned fees of $6,005, all of
which were voluntarily waived. MLAM also reimbursed the Series for
additional expenses of $5,867.

Accounting services are provided to the Series by MLAM at cost.

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

3. Investments:

for the period April 9, 1997 to June 30, 1997 were $39,425,645 and
$6,553,341, respectively.

tax purposes aggregated $3,671,445, of which $4,113,563 related to
appreciated securities and $442,118 related to depreciated
securities. At June 30, 1997, the aggregate cost of investments for
Federal income tax purposes was $36,827,639.

NOTES TO FINANCIAL STATEMENTS


MERRILL LYNCH
AGGREGATE BOND
INDEX FUND

1. Significant Accounting Policies:
Merrill Lynch Aggregate Bond Index Fund (the "Fund") is part of
Merrill Lynch Index Funds, Inc. The Fund is registered under the
Investment Company Act of 1940 as a non-diversified mutual fund. The
Fund seeks to achieve its investment objective by investing all of
its assets in the Merrill Lynch Aggregate Bond Index Series (the
"Series") of the Merrill Lynch Index Trust, which has the same
investment objective as the Fund. The value of the Fund's investment
in the Series reflects the Fund's proportionate interest in the net
assets of the Series. The performance of the Fund is directly
affected by the performance of the Series. The financial statements
of the Series, including the Schedule of Investments, is included
elsewhere in this report and should be read in conjunction with the
Fund's financial statements. These unaudited financial statements
reflect all adjustments which are, in the opinion of management,
necessary to a fair statement of the results for the interim period
presented. All such adjustments are of a normal recurring nature.
The Fund offers two classes of shares, Class A Shares and Class D
Shares. Shares of Class A and Class D are sold without the
imposition of a front-end or deferred sales charge. Both classes of
shares 


                                      68
<PAGE>
 
have identical voting, dividend, liquidation and other rights and the same terms
and conditions, except that Class D Shares bear certain expenses related to the
account maintenance of such shares. The following is a summary of significant
accounting policies followed by the Fund.

(a) Valuation of investments--Valuation of securities is discussed
in Note 1a of the Series' Notes to Financial Statements which is
included elsewhere in this report.

(b) Income--The Fund's net investment income consists of the Fund's
pro rata share of the net invesment income of the Series, less all
actual and accrued expenses of the Fund determined in accordance
with generally accepted accounting principles.

(c) Income taxes--It is the Fund's policy to comply with the require-
ments of the Internal Revenue Code applicable to regulated
investment companies and to distribute all of its taxable income to
shareholders. Therefore, no Federal income tax provision is
required.

(d) Prepaid registration fees and deferred organization expenses--
Prepaid registration fees are charged to expense as the related
shares are issued. Deferred organization expenses are charged to an
expense on a straight-line basis over a five-year period.

(e) Dividends and distributions--Dividends from net investment
income are declared daily and paid monthly. Distributions of capital
gains are recorded on the ex-dividend dates.

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


2. Transactions with Affiliates:
The Fund has entered into a Distribution Agreement and Distribution
Plans with Merrill Lynch Funds Distributor, Inc. ("MLFD" or
"Distributor"), a wholly-owned subsidiary of Merrill Lynch Group,
Inc. Pursuant to a distribution plan (the "Distribution Plan")
adopted by the Fund 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 0.25% based upon the average
daily net assets of Class D Shares.

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

The Fund has also entered into an Administrative Services Agreement
with Merrill Lynch Asset Management, L.P. ("MLAM"). The general
partner of MLAM is Princeton Services, Inc. ("PSI"), a wholly-owned
subsidiary of ML & Co., which is the limited partner. The Fund pays
a monthly fee at an annual rate of 0.14% of the Fund's average daily
net assets for the performance of administrative services (other
than investment advice and related portfolio activities) necessary
for the operation of the Fund. For the period April 3, 1997 to June
30, 1997, MLAM earned fees of $28,078, all of which were waived.
MLAM also reimbursed the Fund for additional expenses of $30,708.

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

Accounting services are provided to the Fund by MLAM at cost.

Certain officers and/or directors of the Fund are officers and/or
directors of MLAM, PSI, MLFD, MLFDS, and/or ML & Co.

3. Investments:

the period April 3, 1997 to June 30, 1997 were $178,182,525 and
$4,146,367, respectively.

Merrill Lynch Aggregate Bond Index Fund, June 30, 1997

NOTES TO FINANCIAL STATEMENTS


MERRILL LYNCH 
AGGREGATE BOND 
INDEX SERIES

1. Significant Accounting Policies:
Merrill Lynch Aggregate Bond Index Series (the "Series") is part of
Merrill Lynch Index Trust (the "Trust"). The Trust is registered
under the Investment Company Act of 1940 and is organized as a
Delaware business trust. These unaudited financial statements
reflect all adjustments which are, in the opinion of management,
necessary to a fair statement of the results for the interim period
presented. All such adjustments are of a normal recurring nature.
The following is a summary of significant accounting policies
followed by the Series.

(a) Valuation of investments--Portfolio securities which are traded
on stock exchanges are valued at the last sale price as of the close
of business on the day the securities are being valued or, lacking
any sales, at the closing bid price. Securities traded in the over-
the-counter market are valued at the last quoted bid price at the
close of trading on the New York Stock Exchange on each day by
brokers that make markets in the securities. Securities traded in
the NASDAQ National Market System are valued at the last sale price
prior to the time of valuation. Portfolio securities which are
traded both on the over-the-counter market and on a stock ex-change
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
over-the-counter market, the last asked price. Options purchas-ed
are valued at the last sale price in the case of exchange-traded
options or, in the case of options traded in the over-the-counter
market, the last bid price. Other investments, including futures
contracts and related options, are stated at market value. Short-
term securities are valued at amortized cost, which approximates
market value. Securities and assets for which market quotations are
not readily available are valued at fair market value, as determined
in good faith by or under the direction of the Trust's Board of
Trustees.

(b) Derivative financial instruments--The Series may engage in
various portfolio investment techniques to provide liquidity, or in
connection with the Series' arbitrage strategies. Losses may arise
due to changes in the value of the contract or if the counterparty
does not perform under the contract.

* Financial futures contracts--The Series may purchase or sell stock
index futures contracts and options on such futures contracts as a
proxy for a direct investment in securities underlying the Series'
index. Upon entering into a contract, the Series deposits and
maintains as collateral such initial margin as required by the
exchange on which the transaction is effected. Pursuant to the
contract, the Series agrees to receive from or pay to the broker an
amount of cash equal to the daily fluctuation in value of the
contract. Such receipts or payments are known as variation margin
and are recorded by the Series as unrealized gains or losses. When
the contract is closed, the Series records a realized gain or loss
equal to the difference between the value of the contract at the
time it was opened and the value at the time it was closed.

* Options--The Series is authorized to purchase and write call and
put options. When the Series writes an option, an amount equal to
the premium received by the Series is reflected as an asset and an
equivalent liability. The amount of the liability is subsequently
marked to market to reflect the current market value of the option
written. When a security is purchased or sold through an exercise of
an option, the related premium paid (or received) is added to (or
deducted from) the basis of the security acquired or deducted from
(or added to) the proceeds of the security sold. When an option
expires (or the Series enters into a closing transaction), the
Series realizes a gain or loss on the option to the extent of the
premiums received or paid (or a gain or loss to the extent that the
cost of the closing transaction exceeds the premium paid or
received).

Written and purchased options are non-income producing investments.

(c) Income taxes--The Series is classified as a partnership for
Federal income tax purposes. As a partnership for Federal income tax
purposes, the Series will not incur Federal income tax liability.
Items of partnership income, gain, loss and deduction will pass
through to investors as partners in the Series. Therefore, no
Federal income tax provision is required.

(d) Security transactions and investment income--Security
transactions are accounted for on the date the securities are
purchased or sold (the trade dates). Dividend income is recorded on
the ex-dividend dates. Interest income (including amortization of
discount) is recognized on the accrual basis. Realized gains and
losses on security transactions are determined on the identified
cost basis.

(e) Deferred organization expenses--Deferred organization expenses
are charged to expense on a straight-line basis over a five-year
period.

2. Investment Advisory Agreement and Transactions
with Affiliates:
The Series has entered into an Investment Advisory Agreement with
Merrill Lynch Asset Management, L.P. ("MLAM"). The general partner
of MLAM is Princeton Services, Inc. ("PSI"), an indirect wholly-
owned subsidiary of Merrill Lynch & Co., Inc. ("ML & Co."), which is
the limited partner.

MLAM 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 0.06%
of the average daily value of the Series' net assets. For the period
April 3, 1997 to June 30, 1997, MLAM earned fees of $12,712, all of
which was voluntarily waived. MLAM also reimbursed the Series for
additional expenses of $5,421.

Accounting services are provided to the Series by MLAM at cost.

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


3. Investments:
Purchases and sales of investments, excluding short-term securities,
for the period April 3, 1997 to June 30, 1997 were $229,141,005 and
$55,314,987, respectively.

Net realized and unrealized gains as of June 30, 1997 were as
follows:

                                     Realized     Unrealized
                                      Gains         Gains

Long-term investments            $    214,770   $    725,479

Total                            $    214,770   $    725,479
                                 ============   ============

As of June 30, 1997, net unrealized appreciation for Federal income
tax purposes aggregated $725,479, of which $835,666 related to
appreciated securities and $110,187 related to depreciated
securities. At June 30, 1997, the aggregate cost of investments for
Federal income tax purposes was $192,525,592.


4. Loaned Securities:
At June 30, 1997, the Series held US Treasury Notes having an
aggregate value of approximately $45,073,000 as collateral for
portfolio securities loaned having a market value of approximately
$44,096,000.

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 Fund is registered under the
Investment Company Act of 1940 as a non-diversified mutual fund. The
Fund seeks to achieve its investment objective by investing all of
its assets in the Merrill Lynch International Index Series (the
"Series") of the Merrill Lynch Index Trust, which has the same
investment objective as the Fund. The value of the Fund's investment
in the Series reflects the Fund's proportionate interest in the net
assets of the Series. The performance of the Fund is directly
affected by the performance of the Series. The financial statements
of the Series, including the Schedule of Investments, are included
elsewhere in this report and should be read in conjunction with the
Fund's financial statements. These unaudited financial statements
reflect all adjustments which are, in the opinion of management,
necessary to a fair statement of the results for the interim period
presented. All such adjustments are of a normal recurring nature.
The Fund offers two classes of shares, Class A Shares and Class D
Shares. Shares of Class A and Class D are sold without the
imposition of a front-end or deferred sales charge. Both classes of
shares 


                                      82
<PAGE>
 
have identical voting, dividend, liquidation and other rights
and the same terms and conditions, except that Class D Shares bear
certain expenses related to the account maintenance of such shares.
The following is a summary of significant accounting policies
followed by the Fund.

(a) Valuation of investments--Valuation of securities is discussed
in Note 1a of the Series' Notes to Financial Statements which are
included elsewhere in this report.

(b) Income--The Fund's net investment income consists of the Fund's
pro rata share of the net investment income of the Series, less all
actual and accrued expenses of the Fund determined in accordance
with generally accepted accounting principles.

(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 all of its taxable income to
shareholders. Therefore, no Federal income tax provision is
required.

(d) Prepaid registration fees and deferred organization expenses--
Prepaid registration fees are charged to expense as the related
shares are issued. Deferred organization expenses are charged to
expense on a straight-line basis over a five-year period.

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

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


2. Transactions with Affiliates:
The Fund has entered into a Distribution Agreement and Distribution
Plans with Merrill Lynch Funds Distributor, Inc. ("MLFD" or
"Distributor"), a wholly-owned subsidiary of Merrill Lynch Group,
Inc. Pursuant to a distribution plan (the "Distribution Plan")
adopted by the Fund 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 0.25% based upon the average
daily net assets of Class D Shares.

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

The Fund has also entered into an Administrative Services Agreement
with Merrill Lynch Asset Management, L.P. ("MLAM"). The general
partner of MLAM is Princeton Services, Inc. ("PSI"), a wholly-owned
subsidiary of ML & Co., which is the limited partner. The Fund pays
a monthly fee at an annual rate of 0.24% of the Fund's average daily
net assets for the performance of administrative services (other
than investment advice and related portfolio activities) necessary
for the operation of the Fund. For the period April 9, 1997 to June
30, 1997, MLAM earned fees of $50,554, of which $23,561 was
voluntarily waived.

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

NOTES TO FINANCIAL STATEMENTS

MERRILL LYNCH
INTERNATIONAL
INDEX SERIES

1. Significant Accounting Policies:
Merrill Lynch International Index Series (the "Series") is part of
Merrill Lynch Index Trust (the "Trust"). The Trust is registered
under the Investment Company Act of 1940 and is organized as a
Delaware business trust. These unaudited financial statements
reflect all adjustments which are, in the opinion of management,
necessary to a fair statement of the results for the interim period
presented. All such adjustments are of a normal recurring nature.
The following is a summary of significant accounting policies
followed by the Series.

(a) Valuation of investments--Portfolio securities which are traded
on stock exchanges are valued at the last sale price as of the close
of business on the day the securities are being valued or, lacking
any sales, at the closing bid price. Securities traded in the over-
the-counter market are valued at the last quoted bid price at the
close of trading on the New York Stock Exchange on each day by
brokers that make markets in the securities. Securities traded in
the NASDAQ National Market System are valued at the last sale price
prior to the time of valuation. Portfolio securities which are
traded both on the over-the-counter 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
over-the-counter market, the last asked price. Options purchased are
valued at the last sale price in the case of exchange-traded options
or, in the case of options traded in the over-the-counter market,
the last bid price. Other investments, including futures contracts
and related options, are stated at market value. Short-term
securities are valued at amortized cost, which approximates market
value. Securities and assets for which market quotations are not
readily available are valued at fair market value, as determined in
good faith by or under the direction of the Trust's Board of
Trustees.

(b) Derivative financial instruments--The Series may engage in
various portfolio investment techniques to provide liquidity, or in
connection with the Series' arbitrage strategies. Losses may arise
due to changes in the value of the contract or if the counterparty
does not perform under the contract.

* Financial futures contracts--The Series may purchase or sell stock
index futures contracts and options on such futures contracts as a
proxy for a direct investment in securities underlying the Series'
index. Upon entering into a contract, the Series deposits and
maintains as collateral such initial margin as required by the
exchange on which the transaction is effected. Pursuant to the
contract, the Series agrees to receive from or pay to the broker an
amount of cash equal to the daily fluctuation in value of the
contract. Such receipts or payments are known as variation margin
and are recorded by the Series as unrealized gains or losses. When
the contract is closed, the Series records a realized gain or loss
equal to the difference between the value of the contract at the
time it was opened and the value at the time it was closed.

* Options--The Series is authorized to purchase and write call and put
options. When the Series writes an option, an amount equal to the
premium received by the Series is reflected as an asset and an
equivalent liability. The amount of the liability is subsequently
marked to market to reflect the current market value of the option
written. When a security is purchased or sold through an exercise of
an option, the related premium paid (or received) is added to (or
deducted from) the basis of the security acquired or deducted from
(or added to) the proceeds of the security sold. When an option
expires (or the Series enters into a closing transaction), the
Series realizes a gain or loss on the option to the extent of the
premiums received or paid (or a gain or loss to the extent that the
cost of the closing transaction exceeds the premium paid or
received).

Written and purchased options are non-income producing investments.

* Forward foreign exchange contracts--The Series is authorized to
enter into forward foreign exchange contracts as a hedge against
either specific transactions or portfolio positions. Such contracts
are not entered on the Series' records. However, the effect on
operations is recorded from the date the Series enters into such
contracts. Premium or discount is amortized over the life of the
contracts.

* 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-US dollar denominated securities owned by the Series,
sold by the Series but not yet delivered, or committed or
anticipated to be purchased by the Series.

(c) 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 US dollars. Realized and unrealized gains or losses
from investments include the effects of foreign exchange rates on
investments.

(d) Income taxes--The Series is classified as a partnership for
Federal income tax purposes. As a partnership for Federal income tax
purposes, the Series will not incur Federal income tax liability.
Items of partnership income, gain, loss and deduction will pass
through to investors as partners in 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.

(e) Security transactions and investment income--Security
transactions are accounted for on the date the securities are
purchased or sold (the trade dates). 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
(including amortization of discount) is recognized on the accrual
basis. Realized gains and losses on security transactions are
determined on the identified cost basis.

(f) Deferred organization expenses--Deferred organization expenses
are charged to expense on a straight-line basis over a five-year
period.


2. Investment Advisory Agreement and Transactions with Affiliates:
The Series has entered into an Investment Advisory Agreement with
Merrill Lynch Asset Management, L.P. ("MLAM"). The general partner
of MLAM is Princeton Services, Inc. ("PSI"), an indirect wholly-
owned subsidiary of Merrill Lynch & Co., Inc. ("ML & Co.") which is
the limited partner.

MLAM 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 0.11%
of the average daily value of the Series' net assets. For the period
April 9, 1997 to June 30, 1997, MLAM earned fees of $23,163, all of
which was voluntarily waived.

Accounting services are provided to the Series by MLAM at cost.

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

INDEPENDENT AUDITORS' REPORT
 
The Board of Directors and Shareholder,
   
Merrill Lynch Index Funds, Inc.     
   
We have audited the accompanying statements of assets and liabilities of the
Merrill Lynch S&P 500 Index Fund, Merrill Lynch SmallCap Index Fund, Merrill
Lynch Aggregate Bond Index Fund and Merrill Lynch International Index Fund of
Merrill Lynch Index Funds, Inc. as of January 17, 1997. These financial
statements are the responsibility of the Fund's management. Our responsibility
is to express an opinion on these financial statements based on our audits.
    
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
   
In our opinion, such statements of assets and liabilities present fairly, in
all material respects, the financial position of the Merrill Lynch S&P 500
Index Fund, Merrill Lynch SmallCap Index Fund, Merrill Lynch Aggregate Bond
Index Fund and Merrill Lynch International Index Fund of Merrill Lynch Index
Funds, Inc. as of January 17, 1997, in conformity with generally accepted

ITEM 27. INDEMNIFICATION.
 
  Reference is made to Article VI of Registrant's Articles of Incorporation,
Article VI of Registrant's By-Laws and Section 2-418 of the Maryland General
Corporation Law.
 
  Article VI of the By-Laws provides that each current and former officer and
Director of the Registrant shall be indemnified by the Registrant to the full
extent permitted under the General Laws of the State of Maryland, except that
such indemnity shall not protect any such person against any liability to the
Registrant or any stockholder thereof to which such person would otherwise be
subject by reason of willful misfeasance, bad faith, gross negligence or
reckless disregard of the duties involved in the conduct of his office. Absent
a court determination that an officer or director seeking indemnification was
not liable on the merits or guilty of willful misfeasance, bad faith, gross
negligence or reckless disregard of the duties involved in the conduct of his
office, the decision by the Registrant to indemnify such person must be based
upon the reasonable determination of independent counsel or non-party
independent directors, after review of the facts, that such officer or director
is not guilty of willful misfeasance, bad faith, gross negligence or reckless
disregard of the duties involved in the conduct of his office.
 
  Each officer and Director of the Registrant claiming indemnification with the
scope of Article VI of the By-Laws shall be entitled to advances from the
Registrant for payment of the reasonable expenses incurred by him in connection
with proceedings to which he is a party in the manner and to the full extent
permitted under the General Laws of the State of Maryland; provided, however,
that the person seeking indemnification shall provide to the Registrant a
written affirmation of his good faith belief that the standard of conduct
necessary for indemnification by the Registrant has been met and a written
undertaking to repay any such advance, if it should ultimately be determined
that the standard of conduct has not been met, and provided further that at
least one of the following additional conditions is met: (a) the person seeking
indemnification shall provide a security in form and amount acceptable to the
Registrant for his undertaking; (b) the Registrant is insured against losses
arising by reason of the advance; (c) a majority of a quorum of non-party
independent directors, or independent legal counsel in a written opinion, shall
determine, based on a review of facts readily available to the Registrant at
the time the advance is proposed to be made, that there is reason to believe
that the person seeking indemnification will ultimately be found to be entitled
to indemnification.
 
  The Registrant may indemnify, make advances or purchase insurance to the
extent provided in Article VI of the By-Laws on behalf of an employee or agent
who is not an officer or Director of the Registrant.
 
  The Registrant has purchased an insurance policy insuring its officers and
Directors against liabilities, and certain costs of defending claims against
such officers and Directors, to the extent such officers and
 
                                      C-3
<PAGE>
 
Directors are not found to have committed conduct constituting willful
misfeasance, bad faith, gross negligence or reckless disregard in the
performance of their duties.
 
  Article IV of the Administration Agreement between Registrant and MLAM
(Exhibit 9(a) hereof) limits the liability of MLAM to liabilities arising from
willful misfeasance, bad faith or gross negligence in the performance of their
respective duties or from reckless disregard of their respective duties and
obligations.
 
  In Section 9 of the Distribution Agreement relating to the securities being
offered hereby, the Registrant agrees to indemnify the Distributor and each
person, if any, who controls the Distributor within the meaning of the
Securities Act of 1933 (the "Act"), against certain types of civil liabilities
arising in connection with the Registration Statement or Prospectus and
Statement of Additional Information.
 
  Insofar as indemnification for liabilities arising under the Act may be
permitted to Directors, officers and controlling persons of the Registrant and
the principal underwriter pursuant to the foregoing provisions or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a Director, officer, or controlling
person of the Registrant and the principal underwriter in connection with the
successful defense of any action, suit or proceeding) is asserted by such
Director, officer or controlling person or the principal underwriter in
connection with the shares being registered, the Registrant will, unless in the
opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.
