Important Tax
Information
None of the net investment income distributions paid monthly by Merrill Lynch
Aggregate Bond Index Fund during the fiscal year ended December 31, 1997 qualify
for the dividends received deduction for corporations. The Fund paid a
short-term capital gain distribution of $0.032317 per share to shareholders of
record on December 22, 1997. Additionally, there were no long-term capital gains
distributed during the year.
The law varies in each state as to whether and what percentage of dividend
income attributable to Federal obligations is exempt from state income tax. We
recommend that you consult your tax adviser to determine if any portion of the
dividends you received is exempt from state income tax.
Listed at right are the percentages of total assets of the Fund invested in
Federal obligations as of the end of each quarter of the fiscal year:
- -------------------------------------------------------------------------
For the Percentage of
Quarter Ended Federal Obligations*

March 31, 1997..................................... N/A
June 30, 1997...................................... 42.94%
September 30, 1997................................. 45.57
December 31, 1997.................................. 45.27
- -------------------------------------------------------------------------
* For purposes of this calculation, Federal obligations include US Treasury
Notes, US Treasury Bills, and US Treasury Bonds. Also included are
obligations issued by the following agencies: Banks for Cooperatives,
Federal Intermediate Credit Banks, Federal Land Banks, Federal Home Loan
Banks, and the Student Loan Marketing Association. Repurchase agreements
are not included in this calculation.
Of the Fund's net investment income distributions paid monthly during the fiscal
year ended December 31, 1997, 49.38% was attributable to Federal obligations. In
calculating the foregoing percentage, Fund expenses have been allocated on a pro
rata basis.

Merrill Lynch Aggregate Bond Index Fund, December 31, 1997
DEAR SHAREHOLDER
Fiscal Year in Review
Merrill Lynch Aggregate Bond Index Fund commenced operations on April 3, 1997 in
an investment environment which proved to be very favorable to investors in
high-quality fixed-income securities. Interest rates declined fairly steadily
throughout the last six months of 1997, allowing securities to appreciate and
generate returns in excess of coupon flow to shareholders. Since inception
(April 3, 1997) through December 31, 1997, the Fund's Class A and Class D Shares
had total returns of +9.49% and +9.29%, respectively. This compares to the total
return of +9.89% for the unmanaged Lehman Brothers Aggregate Bond Index for the
same period. (For complete performance information, including average annual
total returns, see pages 3 and 4 of this report to shareholders.)
The investment objective of the Fund is to seek to provide investment returns
that, before expenses, replicate the total return of the unmanaged Lehman
Brothers Aggregate Bond Index. The Index is comprised of securities from the US
Treasury, agency, mortgage-backed and corporate investment-grade sectors. The
allocation of sectors in the Index is identical to their weighting in the actual
market. As of year-end, the Treasury and agency sectors represented 49.6% of the
Index, with mortgage-backed and corporate securities representing 29.4% and
21.0% of the Index, respectively.
The Fund seeks to achieve its objective by investing all of its assets in
Merrill Lynch Aggregate Bond Index Series. While the sector allocation in the
Series is identical to that of the Index, there is no guarantee that Series
performance will be identical to the Index. This is because the Fund is not an
exact replication of the Index. It does not utilize every security in the Index.
There are currently 6,188 positions in the Index, which makes it too large for
the Series to replicate exactly.
In constructing the Series, securities are selected which, in aggregate, possess
the same investment characteristics as the Index. In constructing the Treasury
and agency sectors, the measures of duration (which measure the amount of price
change when interest rates change) and convexity (which measure the stability of
duration) are identical in the Series and the Index. In addition, an analysis of
the duration exposure is conducted for each part of the yield curve (partial
duration) to ensure identical exposure to the yield curve. This provides comfort
that in the event the shape of the yield curve changes, a deviation in
performance will not result.
A similar approach is applicable in constructing the corporate sector of the
Series. However, in addition to duration, partial duration, and convexity
exercises, credit and industry exposure of the Series is matched to the Index.
The mortgage-backed sector is managed in a slightly different manner. In the
analysis of mortgage-backed securities, the calculation of duration and
convexity is highly dependent on prepayment assumptions of the underlying
mortgages. While there are many models projecting prepayments, there has yet to
emerge a model which can be fully relied upon. As a result, the duration and
convexity measurements may not be accurate. In lieu of these measurements, the
Series' construction is matched by other elements. The Series is neutral to the
mortgage sector in regard to coupon, original term (30-year, 15-year, balloon)
and issuer.
Since the Series is only a proxy of the Index, performance differences between
the Series and the Index (also known as tracking error) are expected to occur to
some extent. Tracking error has been low since inception, since the performance
of the 136 positions held in the Series have followed the performance of the
6,188 positions in the Index fairly closely.
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,

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:
o 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.
o 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 fees applicable to each class, which are
deducted from the income available to be paid to shareholders.

Merrill Lynch Aggregate Bond Index Fund, December 31, 1997
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, are included elsewhere in this report and should be read in
conjunction with the Fund's financial statements. 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 from net investment income are
declared daily and paid monthly. Distributions of capital gains are recorded on
the ex-dividend dates. Distributions in excess of realized capital gains are due
primarily to differing tax treatments for post-October losses.
(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 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 December 31, 1997,
MLAM earned fees of $204,163, of which $139,532 was voluntarily waived. MLAM
also reimbursed the Fund for additional expenses of $77,704.
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:
Increases and decreases in the Fund's investment in the Series for the period
April 3, 1997 to December 31, 1997 were $297,366,838 and $7,375,841,
respectively.
4. Capital Share Transactions:
Net increase in net assets derived from capital share transactions was
$299,978,335 for the period April 3, 1997 to December 31, 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. 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.
o Financial futures contracts--The Series may purchase or sell financial 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.
o 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.
(f) Dollar rolls--The Series may sell securities for delivery in the current
month and simultaneously contract to repurchase substantially similar (same
type, coupon and maturity) securities on a specific future date.

The Board of Trustees and Investors of
Merrill Lynch Index Trust:
We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Merrill Lynch Aggregate Bond Index Series (one
of the series constituting Merrill Lynch Index Trust) as of December 31, 1997,
the related statements of operations and changes in net assets, and the
financial highlights for the period April 3, 1997 (commencement of operations)
to December 31, 1997. These financial statements and the financial highlights
are the responsibility of the Trust's management. Our responsibility is to
express an opinion on these financial statements and the financial highlights
based on our audit.
We conducted our audit 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 and the financial highlights
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. Our
procedures included confirmation of securities owned at December 31, 1997 by
correspondence with the custodian and brokers. 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 audit provides a reasonable basis for our opinion.
In our opinion, such financial statements and financial highlights present
fairly, in all material respects, the financial position of Merrill Lynch
Aggregate Bond Index Series of the Merrill Lynch Index Trust as of December 31,
1997, the results of its operations, the changes in its net assets, and the
financial highlights for the period April 3, 1997 to December 31, 1997 in
conformity with generally accepted accounting principles.
