TO OUR SHAREHOLDERS:

For the year ended March 31, 2000, CMA Arizona Municipal Money Fund paid
shareholders a net annualized yield of 2.80%.* As of March 31, 2000, the Fund's
7-day yield was 3.08%.

Economic Environment

According to recent data released by Arizona's economic outlook center, the
state's economy performed well during the year ended March 31, 2000. The state
finished the year among the top in terms of job creation with the number of jobs
added increasing by 4.1%, second only to Nevada, which recorded 4.4% job growth.
The combination of stable employment growth and weakening labor force growth
allowed Arizona's unemployment rate to begin to fall again. This was reflected
by the state's December unemployment rate, which was reported at 3.7%, down from
4.0% in November. The greater Phoenix area economic outlook remains positive for
the upcoming year. As in the past, the main driver of the local economy
continued to be population growth, which is expected to slow only modestly over
the next two years. The greater Phoenix real estate market also continued to be
strong with activity in the single-family sector remaining extremely high and
the industrial sector anticipating more than 5.8 million square feet of
construction this year. Consequently, the construction industry was a major
source of strength despite some moderation over the past few months.
Construction alone accounted for 17% of all new jobs created over the past year.

Arizona's exports have not returned to the pre-Asian economic crisis level of
1998, although they have begun to rebound. The recovery in the state's exports
was primarily the result of increased shipments to Europe and Mexico since Asian
demand has remained weak. In addition, the aerospace industry has become a
greater presence lately. It currently accounts for more than 13% of
manufacturing employment in the state, compared to 3% nationally. Raytheon Co.
added more than 2,000 employees at its operations in Tucson, and its role as an
employer continues to grow. The state's finances for fiscal year 1999 remained
solid as revenues collected totaled $5.6 billion, $99.4 million above the
estimated amount. The strongest increase in revenues came in estate taxes, which
increased over 38% from the previous year. Additionally, revenues from sales tax
increased 8.8% and individual income taxes collected increased 12.6%. According
to Governor Jane Dee Hull, the increase in revenues will allow an additional
$19.7 million in tax cuts and an extra $20 million for educational programs in
fiscal year 2000.

Investment Strategy

During the year ended March 31, 2000, the persistent strength of the US economy
continued to fuel an already volatile interest rate environment. We began the
period building on CMA Arizona Municipal Money Fund's relatively bearish
position by continuing to reinvest the proceeds of maturing tax-exempt
commercial paper into variable rate products. We did this in an effort to take
advantage of the higher yields that were expected in April and May 1999 as a
result of cash outflows during tax time. As May 1999 ended, a string of economic
data pointing to the presence of inflationary pressures caused concern about
higher interest rates. These factors, along with comments made by Federal
Reserve Board Chairman Alan Greenspan, caused yields on US Treasury securities
to rise significantly as expectations of tighter monetary policy increased. For
example, the yield on the one-year Treasury note, which began the

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


                                                                               1

period at 4.70%, rose to 5.20% by late June, an increase of 50 basis points
(0.50%). On June 30, 1999, the Federal Reserve Board tightened monetary policy
by raising the Federal Funds rate from 4.75% to 5.00%. Given our bearish
position, as well as a meager June inflation report and the need to replace
maturing notes, we purchased some one-year issues. However, with the bulk of the
tax-exempt fixed rate supply expected during the late summer and concerns about
inflation by the Federal Reserve Board once again in July, we maintained our
relatively bearish position for the Fund. On August 24, 1999, the Federal
Reserve Board tightened monetary policy again by increasing the Federal Funds
rate 25 basis points to 5.25%. At that time, we chose to attain a slightly
bullish strategy. The basis for this strategy was twofold. First, comments made
by the Federal Reserve Board after the second interest rate increase were not as
negative as those made following the previous tightening. Second, the
expectation of tighter monetary policy, combined with traditional issuance of
cash flows notes in August and September, caused yields on fixed rate issues to
become more attractive, thus providing a valuable opportunity to take a more
aggressive stance.

The second half of the fiscal year ended March 31, 2000 began with economic data
that continued to point to a US economy that was overheating. Consequently, on
November 16, 1999, the Federal Reserve Board tightened monetary policy a third
time, increasing the Federal Funds rate to 5.50%. Although we expected the
Federal Reserve Board would keep monetary policy on hold through year-end
because of Year 2000 concerns, we anticipated additional tightening of monetary
policy early in 2000. Thus, during this time we managed the Fund's interest rate
risk by purchasing fixed rate issues that matured within 90 days - 120 days in
order to lock in higher yields than were expected in January and February 2000.
As anticipated, the Federal Reserve Board tightened monetary policy by
increasing the Federal Funds rate 25 basis points at both the February and March
2000 Federal Open Market Committee meetings.

Looking ahead, we continue to believe that the Federal Reserve Board may have to
tighten monetary policy at least once more to slow the domestic economy. In
addition, variable rate products traditionally outperform fixed rate products in
April and May because of cash outflows during tax time. Given these factors, we
ended the period with a slightly defensive position. This strategy allowed the
Fund to perform on average relative to its peer group for the year ended March
31, 2000, as measured by IBC's Money Fund Report.

In Conclusion

We thank you for your support of CMA Arizona Municipal Money Fund, and we look
forward to serving your investment needs in the months and years ahead.

CMA ARIZONA MUNICIPAL MONEY FUND
NOTES TO FINANCIAL STATEMENTS
================================================================================

1. Significant Accounting Policies:

CMA Arizona Municipal Money Fund (the "Fund") is part of CMA Multi-State
Municipal Series Trust (the "Trust"). The Fund is registered under the
Investment Company Act of 1940 as a non-diversified, open-end management
investment company. The Fund's financial statements are prepared in accordance
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 Fund.

(a) Valuation of investments--Investments are valued at amortized cost, which
approximates market value. For the purpose of valuation, the maturity of a
variable rate demand instrument is deemed to be the next coupon date on which
the interest rate is to be adjusted. In the case of a floating rate instrument,
the remaining maturity is the demand notice payment period.

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

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

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

(e) Dividends and distributions to shareholders--The Fund declares dividends
daily and reinvests daily such dividends (net of non-resident alien tax and
back-up withholding tax withheld) in additional fund shares at net asset value.
Dividends are declared from the total of net investment income, excluding
discounts earned other than original issue discounts. Net realized capital
gains, if any, are normally distributed annually after deducting prior years'
loss carryforward. The Fund may distribute capital gains more frequently than
annually in order to maintain the Fund's net asset value at $1.00 per share.

2. Investment Advisory Agreement and Transactions with Affiliates:

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

FAM 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 Fund pays a monthly fee
based upon the average daily value of the Fund's net assets, at the following
annual rates: .50% of the first $500 million of average daily net assets; .425%
of average daily net assets in excess of $500 million but not exceeding $1
billion; and .375% of average daily net assets in excess of $1 billion.

Pursuant to the Distribution and Shareholder Servicing Plan in compliance with
Rule 12b-1 under the Investment Company Act of 1940, Merrill Lynch, Pierce,
Fenner & Smith Incorporated ("MLPF&S") receives a distribution fee from the Fund
at the end of each month at the annual rate of .125% of average daily net assets
of the Fund. The distribution fee is to compensate MLPF&S financial consultants
and other directly involved branch office

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

personnel for selling shares of the Fund and for providing direct personal
services to shareholders. The distribution fee is not compensation for the
administrative and operational services rendered to the Fund by MLPF&S in
processing share orders and administering shareholder accounts.

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

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

Certain officers and/or trustees of the Fund are officers and/or directors of
FAM, PSI, FDS, 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. Capital Loss Carryforward:

At March 31, 2000, the Fund had a net capital loss carryforward of approximately
$57,000, of which $6,000 expires in 2004, $30,000 expires in 2005, $6,000
expires in 2006, $5,000 expires in 2007 and $10,000 expires in 2008. This amount
will be available to offset like amounts of any future taxable gains.


                                                                               9

We conducted our audits in accordance with auditing standards generally accepted
in the United States of America. 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 March 31, 2000 by correspondence with the custodian. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, such financial statements and financial highlights present
fairly, in all material respects, the financial position of CMA Arizona
Municipal Money Fund of CMA Multi-State Municipal Series Trust as of March 31,
2000, the results of its operations, the changes in its net assets, and the
financial highlights for the respective stated periods in accordance with
accounting principles generally accepted in the United States of America.
