Merrill Lynch Aggregate Bond Index Fund, June 30, 1997

DEAR SHAREHOLDER


We are pleased to provide you with this first semi-annual report for
Merrill Lynch Aggregate Bond Index Fund. The Fund commenced
operations on April 3, 1997. Our primary objective is to seek to
match the total return, before expenses, of the unmanaged Lehman
Brothers Aggregate Bond Index, a highly recognized benchmark in the
high-quality fixed-income management industry. The Fund seeks to
achieve its objective by investing all of its assets in Merrill
Lynch Aggregate Bond Index Series. To be eligible for inclusion in
the Index, a security must meet certain size, maturity and credit
rating requirements. By June 30, 1997, 6,055 securities were
included in the Index.

The Lehman Brothers Aggregate Bond Index is actually a composite
index comprised of sub-indexes covering the Government, mortgage-
backed and corporate sectors. Accordingly, management of the Series
involves tracking the respective sectors on a neutral basis. Since
the Index is comprised of so many securities, it is not practical to
replicate the Index by including every issue in the Series'
portfolio. Instead, we implement a stratified sampling technique
which collectively has nearly identical investment characteristics
as its referenced benchmark. For example, the 1,475 securities in
the Government index are mimicked by nine securities and are neutral
to the index as far as total duration, partial duration and
convexity are concerned.

The mortgage-backed portion of the Series is managed with a slightly
different approach. The dynamic nature of mortgage analysis leads to
investment uncertainty when attempting to measure characteristics
such as effective duration and effective convexity. Accordingly, we
are less concerned with zero tolerance variance when comparing the
mortgage-backed index with the mortgage-backed portion of the
Series. Rather, we strive to attain sub-sector neutrality by
matching program (Government National Mortgage Association, Federal
National Mortgage Association, or Federal Home Loan Mortgage
Corporation), original term (30-year, 15-year, balloon), seasoning
and coupon. We have achieved this through the purchase of 22
mortgage-backed positions in the Series. The mortgage-backed index
has 628 issues in it.

The corporate index has by far the most issues in the underlying
benchmark. At 3,941 issues, 65% of the issues in the Lehman Brothers
Aggregate Bond Index is represented by the corporate sector.
However, the market value of the corporate sector, at 19.7%, is the
smallest component in the Index. Management of this sector is
similar to the Government sector in that duration and convexity are
matched on a neutral basis. There are additional constraints
however. The subsectors of credit rating and industry are also
matched on a neutral basis. Currently, there are 46 corporate issues
in the Series.

Since the Fund's inception (April 3, 1997) through June 30, 1997,
the total return has lagged that of the Index by approximately 20
basis points (0.20%), a phenomenon known as tracking error. A higher
degree of tracking error is normal during a Fund's initial
investment period. Therefore, we expect the magnitude of tracking
error to diminish in future periods. (For complete performance
information, see page 3 of this report to shareholders.)


In Conclusion
We appreciate your investment in Merrill Lynch Aggregate Bond Index
Fund, and we look forward to sharing our investment outlook with you
in the months and years ahead.

Sincerely,




(Terry K. Glenn)

PERFORMANCE DATA


About Fund
Performance


Investors are able to purchase shares of the Fund through the
Merrill Lynch Select Pricing SM System, which offers two pricing
alternatives:

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

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

None of the past results shown should be considered a representation
of future performance. Figures shown in the "Aggregate Total Return"
tables assume reinvestment of all dividends and capital gains
distributions at net asset value on the payable date. Investment
return and principal value of shares will fluctuate so that shares,
when redeemed, may be worth more or less than their original cost.
Dividends paid to each class of shares will vary because of the
different levels of account maintenance, distribution and transfer
agency fees applicable to each class, which are deducted from the
income available to be paid to shareholders.

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 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.

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.

Merrill Lynch International Index Fund, June 30, 1997

DEAR SHAREHOLDER

We are pleased to provide you with this first semi-annual report for
Merrill Lynch International Index Fund. The Fund, which seeks to
match the returns of the Morgan Stanley Capital International
Europe, Australia, Far East Index--GDP Weighted (MSCI EAFE Index),
commenced operations on April 9, 1997 with an initial inflow of
approximately $44.3 million and starting net asset values per share
of $10.00.

At the Fund's inception on April 9, the MSCI EAFE Index was down
2.9% for the year. The performance, segmented by region during this
period, shows the MSCI Europe Index up 1.3% and MSCI Pacific Index
down 12.8%. Subsequently, the MSCI Pacific Index rebounded strongly,
up 6.6% as of June 30, 1997. Europe also continued its strong
performance, following the lead of the United States, and was up
13.2% by the end of June. The largest contributor to portfolio
performance was Japan, where the MSCI Japan Index was up 27.9% since
the Fund's inception to June 30, 1997. Other contributors included
Germany (+10.0%), France (+7.3%), Italy (+9.4%) and Spain (+22.0%).
The only negative performers for the Fund were Malaysia (-8.5%) and
Singapore (-3.5%).


Portfolio Matters
The Fund invests all of its assets in 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. There are two principal
investments made by the Series in its attempt to replicate the
returns of the MSCI EAFE Index--GDP Weighted. Because execution
costs in many of the foreign markets in the MSCI EAFE Index are
relatively high, the Series uses a statistical technique called
"optimization", whereby a group of stocks in the MSCI EAFE Index are
statistically selected to provide returns which closely approximate
those of the Index. At inception, the Series purchased a basket of
350 stocks. In addition, the Series holds futures contracts used
primarily as a means of equitizing daily cash inflows. These futures
contracts are also an extremely efficient method of keeping a pool
of liquidity available to meet potential redemption activity. As of
the end of June, the equity portfolio of the Series was valued at
$107.1 million, and the Series held futures contracts with an
underlying value of $22.0 million.

There was one major addition to  the MSCI EAFE Index during this
period--Nippon Telegraph & Telephone Corp. was added to the MSCI
Japan Index on May 30, 1997. Its initial weight in the MSCI EAFE
Index was approximately 1.9%. Such changes generally reflect merger
or acquisition activity involving one or more constituents of the
MSCI EAFE Index.

The Fund's net assets grew steadily since inception through the end
of the second quarter, and by June 30, 1997 stood at $127.6 million.
Since inception (April 9, 1997) through June 30, 1997, Merrill Lynch
International Index Fund's Class A Shares and Class D Shares both
had total returns of +15.20%, based on a change in per share net
asset value from $10.00 to $11.52. (Complete performance
information, including aggregate total returns, can be found on page
3 of this report to shareholders.)


In Conclusion
We appreciate your investment in Merrill Lynch International Index
Fund, and we look forward to sharing our investment outlook with you
in the months and years ahead.


Sincerely,




(Terry K. Glenn)

President

PERFORMANCE DATA


About Fund
Performance

Investors are able to purchase shares of the Fund through the
Merrill Lynch Select Pricing SM System, which offers two pricing
alternatives:

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

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

None of the past results shown should be considered a representation
of future performance. Figures shown in the "Aggregate Total Return"
tables assume reinvestment of all dividends and capital gains
distributions at net asset value on the ex-dividend date. Investment
return and principal value of shares will fluctuate so that shares,
when redeemed, may be worth more or less than their original cost.
Dividends paid to each class of shares will vary because of the
different levels of account maintenance, distribution and transfer
agency fees applicable to each class, which are deducted from the
income available to be paid to shareholders.

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 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.

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.

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

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.

Merrill Lynch SmallCap Index Fund, June 30, 1997

DEAR SHAREHOLDER


We are pleased to provide you with this first semi-annual report for
Merrill Lynch Small Cap Index Fund. The Fund, which seeks to
replicate the return of the Russell 2000 Index, commenced operations
on April 9, 1997 with an initial inflow of approximately $28.9
million and starting net asset values per share of $10.00. The Fund
seeks to achieve its objective by investing all of its assets in
Merrill Lynch Small Cap Index Series (the Series) of the Merrill
Lynch Index Trust, which has the same investment objective of the
Fund. The value of the Fund's investment in the Series reflects the
Fund's proportionate interest in the net asset of the Series.

At the Fund's inception, the US equity market, as measured by the
Standard & Poor's 500 Index (S&P 500), was in the midst of a nearly
10% correction, following the preemptive increase in short-term
interest rates by the Federal Open Market Committee on March 25,
1997. Small-capitalization stocks, which had badly lagged their
large-cap counterparts during the early part of the year, staged a
powerful rebound beginning in May, and produced a total return for
that month of +11.12%, the best monthly result since February 1991.
May was also the first month since December 1996 in which the
Russell 2000 Index outperformed the S&P 500. In June, the unmanaged
Russell 2000 Index continued to show strong momentum, producing a
total return of +4.29%, bringing its total return for the second
quarter to +16.21%.

There are two principal investments made by the Series in its
attempt to replicate the returns of the benchmark Russell 2000
Index. The primary investment of the Series is an underlying equity
portfolio in which most of the Series' assets are placed; the other
is a long position in futures contracts used as a mechanism to
equitize daily cash inflows so that the Series may remain 100%
invested, while providing a means of maintaining a liquid pool of
assets to meet potential redemption activity.

Because there is such a large number of stocks in the benchmark, and
because many of these stocks are illiquid, we invest in an
"optimized" portfolio of equities, whereby a group of stocks in the
Russell 2000 Index are statistically selected to provide returns
which closely approximate those of the Russell 2000 Index. The
initial investment of the Series was a portfolio consisting of 800
stocks. As of June 30, 1997, the Series' equity portfolio was valued
at $37.3 million. In addition, the Series held a long position of 12
Russell 2000 September futures and 6 S&P MidCap 400 futures.

Since inception through June 30, 1997, Merrill Lynch Small Cap Index
Fund's Class A Shares and Class D Shares both had total returns of
+15.10%, based on a change in per share net asset value from $10.00
to $11.51. (For complete performance information, see page 3 of this
report to shareholders.)

In Conclusion
We appreciate your investment in Merrill Lynch Small Cap Index Fund,
and we look forward to sharing our investment outlook with you in
the months and years ahead.

Sincerely,







(Terry K. Glenn)

PERFORMANCE DATA


About Fund
Performance


Investors are able to purchase shares of the Fund through the
Merrill Lynch Select Pricing SM System, which offers two pricing
alternatives:

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

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

None of the past results shown should be considered a representation
of future performance. Figures shown in the "Aggregate Total Return"
tables assume reinvestment of all dividends and capital gains
distributions at net asset value on the ex-dividend date. Investment
return and principal value of shares will fluctuate so that shares,
when redeemed, may be worth more or less than their original cost.
Dividends paid to each class of shares will vary because of the
different levels of account maintenance, distribution and transfer
agency fees applicable to each class, which are deducted from the
income available to be paid to shareholders.

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. 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

NOTES TO FINANCIAL STATEMENTS

MERRILL LYNCH 
SMALL CAP
INDEX SERIES


1. Significant Accounting Policies:
Merrill Lynch Small Cap 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 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.

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

DEAR SHAREHOLDER


We are pleased to provide you with this first semi-annual report for
Merrill Lynch S&P 500 Index Fund. The Fund commenced operations on
April 3, 1997 with an initial inflow of approximately $53.8 million
and a net asset value per share of $10.00.

At the time of the Fund's inception, the US equity market was in the
midst of a nearly 10% correction, following the preemptive increase
in short-term interest rates by the Federal Open Market Committee on
March 25, 1997. The stock market's decline began soon after the
commencement of the Fund, culminating in a 20.69 point drop in the
Standard & Poor's 500 Index (S&P 500) on April 11. This was the S&P
500's third-largest decline in history, closing at 737.65, 9.63% off
the high established in mid-February. This became the launching
point for a powerful second-quarter rebound for the S&P 500,
propelled by continued prospects for subdued inflation and a
rallying bond market. For the month of May, the unmanaged S&P 500
produced a total return of +6.01%, exactly matching its return for
the month of April. In June, the market continued to show strong
momentum with a total return of +4.49%. This brought the S&P 500's
total return for the second quarter to +17.43%. Having ended 1996 at
740.74, the S&P 500 completed the first half of 1997 with a gain of
144 points, up 19.49%, to close at 885.14 on June 30.

The Fund invests all of its assets in 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. There are two principal investments
made by the Series in its attempt to replicate the returns of the
S&P 500. First, the Series holds a fully replicating portfolio of
all 500 stocks which comprise the S&P 500, with share quantities
designed to closely approximate each company's actual weight in the
S&P 500. In addition, the Series holds a long position of S&P 500
futures contracts, used primarily as a means of equitizing daily
cash inflows. These futures contracts also provide an extremely
efficient mechanism for keeping a pool of liquid assets available to
meet potential redemption activity. As of the end of June, the
Series' equity portfolio was valued at $252.0 million, and the
Series held a long position of 98 S&P 500 September 1997 futures
contracts with an underlying value of $43.6 million.

Several new equity positions were added to the Series by the end of
June, in response to changes to the S&P 500 made by Standard & Poor's
Corp. Such changes generally reflect merger or acquisition activity
involving one or more constituents of the S&P 500. Portfolio
additions were: Adobe Systems, Inc. on May 5; Cardinal Health, Inc.
on May 23; Charles Schwab, Inc. on May 30; Countrywide Credit
Industries Inc. on June 17; and Equifax Inc. on June 18.

The Fund's net assets grew rapidly from its inception through the
end of the second quarter, and by June 30, 1997 stood at $295.3
million. Since inception through June 30, 1997, Merrill Lynch 
S&P 500 Index Fund's Class A Shares and Class D Shares both had total
returns of +18.40% based on a change in per share net asset value
from $10.00 to $11.84. (For complete performance information, see
page 3 of this report to shareholders.)


In Conclusion
We appreciate your investment in Merrill Lynch S&P 500 Index Fund,
and we look forward to sharing our investment outlook with you in
the months and years ahead.

Sincerely,




(Terry K. Glenn)
Terry K. Glenn
President

PERFORMANCE DATA


About Fund
Performance

Investors are able to purchase shares of the Fund through the
Merrill Lynch Select Pricing SM System, which offers two pricing
alternatives:

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

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

None of the past results shown should be considered a representation
of future performance. Figures shown in the "Aggregate Total Return"
tables assume reinvestment of all dividends and capital gains
distributions at net asset value on the ex-dividend date. Investment
return and principal value of shares will fluctuate so that shares,
when redeemed, may be worth more or less than their original cost.
Dividends paid to each class of shares will vary because of the
different levels of account maintenance, distribution and transfer
agency fees applicable to each class, which are deducted from the
income available to be paid to shareholders.

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 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.

for the period April 3, 1997 to June 30, 1997 were $228,929,113 and
$1,847,984, respectively.

Federal income tax purposes was $267,065,276.
