TO OUR SHAREHOLDERS:

For the six-month period ended September 30, 2000, CMA Arizona Municipal Money
Fund paid shareholders a net annualized yield of 3.51%.* As of September 30,
2000, the Fund's 7-day yield was 3.87%.

Economic Environment

Arizona's economy continued to grow rapidly during the six months ended
September 30, 2000. According to the latest Department of Economic Statistics'
employment numbers, growth in the state has actually reaccelerated. After
growing by 4.1% for all of 1999, Arizona's employment was up 4.7% for the first
half of 2000. Moreover, nearly every industry experienced healthy growth, led by
the service industry, which now accounts for more than half of the jobs created
in the state. This continued strength in Arizona's job market has produced
strong income growth and improved credit conditions, causing the number of
bankruptcies per capita to fall below the national average. Consequently, retail
sales were up 10.5% over last year for the first half of 2000 and up 9.9%,
excluding autos. After almost two years of decline, the state's manufacturing
sector is finally on its way to recovery. For example, from January 2000 through
June 2000 manufacturing employment in the state rose 1.7%, its highest level
since October 1998 when problems with Asian economies first occurred. Likewise,
in the greater Phoenix area manufacturing employment also increased in June, the
first month-over-month increase since November 1998.

Arizona continues to experience strong population growth, contributing to strong
demand for housing as well as growth in the service and trade industries. Net
migration into Arizona did slow somewhat in 1999, but still contributed to more
than 60% of the state's population growth. Specifically, Maricopa County, which
is the largest county in the state, has been the nation's fastest growing in
terms of population over the past decade. Its population of 2.8 million is up
35% from the last census and is equal to 60% of the statewide total. This
migration has also kept construction employment strong, which, while slowing
from the rapid rates of growth in the past few years, was up 4.9% over the first
half of the year.

Additionally, Arizona exports grew 23% in the first quarter of 2000 as compared
to a year ago, nearly twice the increase of 12.5% seen nationwide. While Mexico
continues to be the number one destination for Arizona products, strong growth
in sales to Singapore (up 112%) and the United Kingdom (up 56%) were also noted.
In respect to product category, aircraft and spacecraft exports led the way as
sales increased 67% during the first half of the year. Finally, during July
Governor Jane Dee Hull signed an education bill that will be placed on the
November ballot for public approval. The bill requires a new education sales tax
that would divide funding among issues such as higher teacher salaries, smaller
classroom sizes and technology development.

Investment Strategy

CMA Arizona Municipal Money Fund began the six-month period ended September 30,
2000 with a relatively bearish position. This was because variable rate demand
products traditionally outperform fixed rate products in April and May as a
result of outflows during tax time. Nonetheless, we anticipated moving the Fund
to a more neutral stance by June, given our opinion that tighter monetary
policy,

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


                                                                               1

which was causing US equity markets to weaken, would soon have a negative impact
on the domestic economy. It was also the case that the lack of short-term
tax-exempt issuance and traditional cash inflows in early June and July caused
variable rate products to underperform fixed rate products. Conversely, as the
period began a number of economic indicators, including strong retail sales and
housing activity, reflected a still-healthy US economy, while the nation's
unemployment rate dropped to 3.9% in April. Thus, we delayed the Fund's
extension in response to these factors.

On May 16, 2000, the Federal Reserve Board tightened monetary policy by
increasing the Federal Funds rate 50 basis points (0.50%) from 6.00% to 6.50%.
Given this significant tightening of monetary policy, we then looked to move to
the more neutral stance anticipated at the beginning of the period. For the
six-month period ended September 30, 2000, the state of Arizona's issuance
totaled $81.1 million. As we entered the second half of the period, an
increasing portion of the economic data began to reflect a domestic economy that
was softening. For example, in both July and August the change in non-farm
payrolls was significantly weaker than expected, decreasing 108,000 and
increasing only 53,000, respectively. The battered equity indexes also had
trouble rebounding from their lows as the Dow Jones Industrial Average fell over
5%, while the NASDAQ Composite Index lost almost 15% of its value. Inflation
also stayed in check as both the consumer and producer price indexes recorded
negative values during the month of August. Given this backdrop for the domestic
economy, we believed that a moderate slowdown could be at hand. Thus, during the
remainder of the period we continued to move to a slightly more aggressive
position when prudent. We accomplished this primarily in July and August when
the traditional increase in fixed rate issuance provided an opportunity to lock
in attractive yields. This strategy allowed the Fund to perform on average
relative to its peer group during the period, 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.

Sincerely,

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 conformity
with accounting principles generally accepted in the United States of America,
which may require the use of management accruals and estimates. 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 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
backup 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


                                                                               9

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

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 periods
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.
