Merrill Lynch Ready Assets Trust, December 31, 2002


DEAR SHAREHOLDER


For the year ended December 31, 2002, Merrill Lynch Ready Assets
Trust paid shareholders a net annualized dividend of 1.40%.* For the
six-month period ended December 31, 2002, the Trust paid
shareholders a net annualized dividend of 1.26%.* The Trust's 7-day
yield as of December 31, 2002 was .95%.

The average portfolio maturity for Merrill Lynch Ready Assets Trust
at December 31, 2002 was 56 days, compared to 58 days at June 30,
2002.


Economic Environment
By December 31, 2002, the U.S. economy appeared to be on track for
annual growth of roughly 2.5%, with growth in the fourth quarter of
2002 declining to an estimated 1% from a relatively strong 4% in the
third quarter. Most analysts do not expect consumers to continue to
support economic growth in 2003 as they had in 2002. Large-scale
layoff announcements in the fourth quarter and uncertainty over Iraq
led to a decline in consumer confidence. Industry surveys indicated
that consumers were still uneasy about the employment situation.
These factors contributed to the anemic holiday season, with modest
gains in overall sales limited by heavy discounting needed to bring
buyers into the stores. The strength in the housing market and
mortgage refinancing activity provided household well-being during
the six-month period ended December 31, 2002, but there are signs
this trend is tapering off as mortgage rates have stopped dropping.
After more than two years of retrenchment, corporate balance sheets
improved during the six-month period. It remains unclear if this
will lead to an increase in capital expenditures unless revenues
show signs of growth. However, the combination of low interest rates
and proposed fiscal stimulus may yet bring improvement to the
economic outlook.


*Based on a constant investment throughout the period, with
dividends compounded daily, and reflecting a net return to the
investor after all expenses.


The impact of economic data continued to be muted in light of other
events that have brought increased volatility to the markets. The
short end of the U.S. Treasury market (two years and under) was
subject to a safe-haven trade during the last few months, with U.S.
Treasury yields approaching historical lows. The equity and
corporate bond markets continued to slide from the disclosure of
questionable accounting and business practices. The threat of a U.S.
military conflict with Iraq cast a pall on financial markets, with
volatility accelerating along with the rhetoric. Increasingly, the
decline in the U.S. dollar compared to other major currencies and
recent highs in oil and gold prices added another element to the
uncertainties facing the markets. We believe that fiscal stimulus
will lead to increased borrowing by the U.S. Treasury, and changes
in the borrowings mix are likely to produce structural changes to
the yield curve. These factors influenced the markets during the
fourth quarter of 2002, and we believe are likely to continue, to
varying degrees, into the first quarter of 2003.


Portfolio Matters
Our desired portfolio mix and average duration remained relatively
unchanged during the six-month period ended December 31, 2002. To
target a 50-day - 60-day average life, we favored an overweight
position in variable rate notes, and for fixed rate exposure, we
preferred callable agency structures. The universe of available
first-tier corporate credits declined throughout the year, thus
collapsing spreads because of scarcity value. Somewhat surprisingly,
spreads on agency issues remained unchanged. We added floating rate
agency securities on a one-month London Interbank Offered Rate
(LIBOR) less an eight basis point (.08%) equivalent, which
represented a similar level to that of first-tier commercial paper.
Sufficient exposure in variable rate product should provide adequate
protection against imminently higher interest rates and allow us
greater flexibility with our fixed rate purchases, as we expect
higher interest rates to eventually produce a steeper curve. Amid
the flat-to-inverted yield curve environment in the middle part of
the year, we became increasingly involved in callable agency paper.
With two-year volatility at all-time highs, we believed the premiums
we received by selling imbedded call options created valuable
investment opportunities, especially given the inversion of the
LIBOR curve in the front end. This scenario enabled us to generate
yields that were otherwise unavailable for the higher-quality
credits, which we were primarily focused on in this extremely credit-
sensitive environment. At these volatility levels, callable bonds
had superior option-adjusted spreads in addition to their higher
coupons.



Merrill Lynch Ready Assets Trust, December 31, 2002


Recently, we have become increasingly cautious of adding any new
longer-exposure issues as volatility has declined, quality spreads
have collapsed and U.S. Treasury yields have re-tested their lows.
Therefore, we no longer see value in callable structures, as their
option-adjusted spreads are far less compelling. We remain content
to allow our duration target to passively drift lower, awaiting
better buying opportunities, which we believe may arise if a
resolution with Iraq is reached and/or the possibility of a
Republican-led tax stimulus package increases.

report to shareholders is detailed below:

Merrill Lynch Ready Assets Trust, December 31, 2002


NOTES TO FINANCIAL STATEMENTS


1. Significant Accounting Policies:
Merrill Lynch Ready Assets Trust (the "Trust") is registered under
the Investment Company Act of 1940 as a diversified, open-end
management investment company. The Trust's financial statements are
prepared in conformity with accounting principles generally accepted
in the United States of America, which may require the use of
management accruals and estimates. The following is a summary of
significant accounting policies followed by the Trust.

(a) Valuation of investments--Portfolio securities with remaining
maturities of greater than sixty days, for which market quotations
are readily available, are valued at market value. As securities
transition from sixty-one to sixty days to maturity, the difference
between the valuation existing on the sixty-first day before
maturity and maturity value is amortized on a straight-line basis to
maturity. Securities maturing sixty days or less from their date of
acquisition are valued at amortized cost, which approximates market
value. For purposes of valuation, the maturity of a variable rate
security is deemed to be the next coupon date on which the interest
rate is to be adjusted. Other investments and assets for which
market quotations are not available are valued at fair value as
determined in good faith by or under the direction of the Board of
Trustees.

(b) Repurchase agreements--The Trust invests in U.S. government
securities pursuant to repurchase agreements. Under such agreements,
the counterparty agrees to repurchase the security at a mutually
agreed upon time and price. The Trust takes possession of the
underlying securities, marks to market such securities and, if
necessary, receives additions to such securities daily to ensure
that the contract is fully collateralized. If the counterparty
defaults and the fair value of the collateral declines, liquidation
of the collateral by the Trust may be delayed or limited.

(c) Income taxes--It is the Trust'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
its shareholders. Therefore, no Federal income tax provision is
required.

(d) Security transactions and investment income--Security
transactions are recorded on the dates the transactions are entered
into (the trade dates). Realized gains and losses on security
transactions are determined on the identified cost basis. Interest
income (including amortization of premium and discount) is
recognized on the accrual basis.

(e) Prepaid registration fees--Prepaid registration fees are charged
to expense as the related shares are issued.

(f) Dividends and distributions to shareholders--The Trust declares
dividends daily and reinvests daily such dividends (net of non-
resident alien tax and backup withholding tax) in additional shares
of beneficial interest at net asset value. Dividends are declared
from net investment income and distributions from net realized gain
or loss on investments.


2. Investment Advisory Agreement and Transactions with Affiliates:
The Trust has entered into an Investment Advisory Agreement with
Merrill Lynch Investment Managers, L.P. ("MLIM"). The general
partner of MLIM is Princeton Services, Inc. ("PSI"), an indirect,
wholly-owned subsidiary of Merrill Lynch & Co., Inc. ("ML & Co."),
which is the limited partner. The Trust has also entered into a
Distribution Agreement and Distribution Plan with FAM Distributors,
Inc. ("FAMD" or the "Distributor"), which is a wholly-owned
subsidiary of Merrill Lynch Group, Inc.

MLIM provides the Trust with investment management, research,
statistical, and advisory services, and pays certain other expenses
of the Trust. For such services, the Trust pays a monthly fee based
upon the average daily value of the Trust's net assets at the
following annual rates:


Portion of average daily value of net assets:               Rate

Not exceeding $500 million                                  .500%
In excess of $500 million but not exceeding $1 billion      .400%
In excess of $1 billion but not exceeding $5 billion        .350%
In excess of $5 billion but not exceeding $10 billion       .325%
In excess of $10 billion but not exceeding $15 billion      .300%
In excess of $15 billion but not exceeding $20 billion      .275%
In excess of $20 billion                                    .250%




Merrill Lynch Ready Assets Trust, December 31, 2002


NOTES TO FINANCIAL STATEMENTS (concluded)


The Trust has adopted a Shareholder Servicing Plan and Agreement in
accordance with Rule 12b-1 under the Investment Company Act of 1940,
pursuant to which Merrill Lynch, Pierce, Fenner and Smith
Incorporated ("MLPF&S"), a wholly-owned subsidiary of ML & Co.,
receives a fee each month from the Trust at the annual rate of .125%
of average daily net assets of the accounts of Trust shareholders
who maintain their Trust accounts through MLPF&S. This fee is to
compensate MLPF&S financial consultants and other directly involved
branch office personnel for providing direct personal services to
shareholders. The fee is not compensation for administrative
services.

Financial Data Services, Inc. ("FDS"), a wholly-owned subsidiary of
ML & Co., is the Trust's transfer agent.

For the year ended December 31, 2002, the Trust reimbursed MLIM
$101,492 for certain accounting services.

Certain officers and/or trustees of the Trust are officers and/or
directors of MLIM, FDS, MLPF&S, PSI, FAMD, and/or ML & Co.


3. Shares of Beneficial Interest:
The number of shares sold, reinvested and redeemed during the years
corresponds to the amounts included in the Statements of Changes in
Net Assets for net proceeds from sale of shares, value of shares
reinvested and cost of shares redeemed, respectively, since shares
are recorded at $1.00 per share.


4. Distributions to Shareholders:
The tax character of distributions paid during the fiscal years
ended December 31, 2002 and December 31, 2001 was as follows:


                                      12/31/2002        12/31/2001

Distributions paid from:
   Ordinary income                  $ 80,954,052       $236,976,581
                                    ------------       ------------
Total taxable distributions         $ 80,954,052       $236,976,581
                                    ============       ============


As of December 31, 2002, there were no significant differences
between the book and tax components of net assets.
