TO OUR SHAREHOLDERS
The Municipal Market Environment
During the six months ended January 31, 2000, continued strong domestic growth,
gradual improvement in foreign economies and investor concerns regarding future
inflationary pressures pushed long-term fixed-income bond yields higher. The
Federal Reserve Board continued to raise short-term interest rates in August and
November 1999 as well as just after the period's close, seeking to moderate US
economic growth and maintain the existing benign inflationary environment. US
economic growth, in part intensified by Year 2000 preparations, grew 5.8% during
the last fiscal quarter of 1999 and had an annual rate of 4.1% for 1999. A
number of inflationary indicators have also begun to signal some increase in
price pressures.
However, most investors believe that the Federal Reserve Board will be extremely
vigilant in preventing such pressures from any material escalation. US Treasury
bond yields responded by rising approximately 60 basis points (0.60%) by
mid-January 2000. A strong rally, largely based upon an expected significant
reduction in the future supply of US Treasury 30-year maturity bonds, pushed
yields lower to 6.50% at January 31, 2000. Over the last six months, yields on
30-year US Treasury bonds rose approximately 40 basis points.
The tax-exempt bond market was also under pressure throughout the entire period.
Despite receiving more than $30 billion in coupon payments, bond matu-rities and
proceeds from early redemptions in December and January, overall investor demand
has diminished. It is likely that the returns generated by the US equity market
have continued to attract investor attention and have left little demand for
competing investment alternatives. At January 31, 2000, the long-term tax-exempt
revenue bond yield, as measured by the Bond Buyer Revenue Index, was 6.34%, an
increase of nearly 70 basis points over the last six months.
Issuance by municipalities has significantly declined in recent months. Over the
last six months, less than $100 billion in long-term tax-exempt bonds were
issued, representing a decline of over 20% compared to the same period a year
ago. During the last three months, less than $45 billion in long-term bonds were
issued by various municipalities. This most recent quarterly issuance is 30%
below the level of the January 31, 1999 quarter. Additionally, during January
2000, less than $8 billion in municipal debt was underwritten, down more than
50% from January 1999 levels. This represents the lowest monthly issuance in
over five years. Toward the end of 1999, consensus estimates for 2000 annual
issuance were in the $210 billion-$215 billion range. January's underwritings,
as well as those expected to be issued in the near future, have led some
analysts to revise their forecasts to the $190 billion range.
We believe an overall reduction in bond supply in the coming year should help
support the municipal bond market's overall technical position. While tax-exempt
bond yields, which are at their highest level in over three years, have
attracted significant retail investor interest, institutional demand declined
sharply. Long-term municipal mutual funds have seen consistent outflows in
recent months as the yields of individual securities rose faster than those of
larger, more diverse mutual funds. During the six months ended January 31, 2000,
tax-exempt mutual funds have had net redemptions of approximately $9 billion.
Also, the demand from property and casualty insurance companies has weakened as
a result of the losses and anticipated losses incurred from a series of damaging
storms across much of the eastern United States. Additionally, many
institutional investors who have in recent years been attracted to the municipal
bond market by historically attractive tax-exempt bond yield ratios of over 90%,
found other asset classes even more attractive. Even with a reduced supply
position, tax-exempt issuers have been forced to repeatedly raise municipal bond
yields in an attempt to attract adequate demand. We believe a reduced bond
supply going forward is likely to promote a more closely balanced supply/demand
structure and foster a more stable tax-exempt interest rate environment.
Looking ahead, it appears to us that long-term tax-exempt bond yields will
remain under pressure, trading in a broad range centered around current levels.
Investors are also likely to remain concerned regarding future action by the
Federal Reserve Board in early 2000. Any improvement in bond prices may be
contingent upon weakening in both US employment

growth and consumer spending. The 100 basis point rise in US Treasury bond
yields seen thus far could negatively affect US economic growth. The US housing
market is likely to be among the first sectors to be affected, as some declines
have already been evidenced because of higher mortgage rates. We believe it is
also unrealistic to expect double-digit returns in US equity markets to continue
indefinitely. Much of the US consumer's wealth is tied to recent stock market
appreciation. Any slowing in these incredible growth rates may reduce consumer
spending. We believe that these factors suggest that the worst of the recent
increase in bond yields has passed and stable, if not slightly improving, bond
prices may be expected.
Portfolio Strategy
During the six months ended January 31, 2000, our strategy for the Fund focused
on seeking to enhance state and Federal tax-exempt income through a fully
invested position in quality Arizona municipal credits. The Fund experienced low
turnover because of sparse primary issuance in Arizona and a relatively inactive
illiquid secondary market. Because of the Fund's low duration, we were able to
insulate the Fund from the price deterioration that occurred as interest rates
rose.
Eventually, as the economic backdrop for fixed-income securities becomes more
conducive to lower interest rates, we will look to position the Fund in a more
aggressive position. At the present time, signs of an economic slowdown are not
imminent, so the Fund will remain with an above-average coupon structure,
enabling it to generate an attractive level of current income.
In Conclusion
We appreciate your ongoing interest in Merrill Lynch Arizona Municipal Bond
Fund, and we look forward to assisting you with your financial needs in the
months and years ahead.

PERFORMANCE DATA
About Fund Performance
Investors are able to purchase shares of the Fund through the Merrill
Lynch Select Pricing(SM) System, which offers four pricing alternatives:
o Class A Shares incur a maximum initial sales charge (front-end load) of 4%
and bear no ongoing distribution or account maintenance fees. Class A
Shares are available only to eligible investors.
o Class B Shares are subject to a maximum contingent deferred sales charge
of 4% if redeemed during the first year, decreasing 1% each year
thereafter to 0% after the fourth year. In addition, Class B Shares are
subject to a distribution fee of 0.25% and an account maintenance fee of
0.25%. These shares automatically convert to Class D Shares after
approximately 10 years. (There is no initial sales charge for automatic
share conversions.)
o Class C Shares are subject to a distribution fee of 0.35% and an account
maintenance fee of 0.25%. In addition, Class C Shares are subject to a 1%
contingent deferred sales charge if redeemed within one year of purchase.
o Class D Shares incur a maximum initial sales charge of 4% and an account
maintenance fee of 0.10% (but no distribution fee).
None of the past results shown should be considered a representation of
future performance. Figures shown in the "Recent Performance Results" and
"Average Annual 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.

Merrill Lynch Arizona Municipal Bond Fund January 31, 2000
NOTES TO FINANCIAL STATEMENTS
1. Significant Accounting Policies:
Merrill Lynch Arizona Municipal Bond Fund (the "Fund") is part of Merrill Lynch
Multi-State Municipal Series Trust (the "Trust"). The Fund is registered under
the Investment Company Act of 1940 as a diversified, open-end management
investment company. The Fund's financial statements are prepared in accordance
with generally accepted accounting principles, 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 Fund offers four classes of shares under
the Merrill Lynch Select Pricing(SM) System. Shares of Class A and Class D are
sold with a front-end sales charge. Shares of Class B and Class C may be subject
to a contingent deferred sales charge. All classes of shares have identical
voting, dividend, liquidation and other rights and the same terms and
conditions, except that Class B, Class C and Class D Shares bear certain
expenses related to the account maintenance of such shares, and Class B and
Class C Shares also bear certain expenses related to the distribution of such
shares. Each class has exclusive voting rights with respect to matters relating
to its account maintenance and distribution expenditures. The following is a
summary of significant accounting policies followed by the Fund.
(a) Valuation of investments--Municipal bonds and other portfolio securities in
which the Fund invests are traded primarily in the over-the-counter municipal
bond and money markets and are valued at the last available bid price in the
over-the-counter market or on the basis of yield equivalents as obtained from
one or more dealers that make markets in the securities. Financial futures
contracts and options thereon, which are traded on exchanges, are valued at
their settlement prices as of the close of such exchanges. Short-term
investments with remain- ing maturities of sixty days or less are valued at
amortized cost, which approximates market value. Securities and assets for which
market quotations are not readily available are valued at fair value as
determined in good faith by or under the direction of the Board of Trustees of
the Trust, including valuations furnished by a pricing service retained by the
Trust, which may utilize a matrix system for valuations. The procedures of the
pricing service and its valuations are reviewed by the officers of the Trust
under the general supervision of the Trustees.
(b) Derivative financial instruments--The Fund may engage in various portfolio
strategies to seek to increase its return by hedging its portfolio against
adverse movements in the debt markets. 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 Fund may purchase or sell financial futures
contracts and options on such futures contracts for the purpose of hedging the
market risk on existing securities or the intended purchase of securities.
Futures contracts are contracts for delayed delivery of securities at a specific
future date and at a specific price or yield. Upon entering into a contract, the
Fund deposits and maintains as collateral such initial margin as required by the
exchange on which the transaction is effected. Pursuant to the contract, the
Fund 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 Fund as unrealized gains or losses.
When the contract is closed, the Fund 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.
(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 substantially all of its taxable income to its shareholders.
Therefore, no Federal income tax provision is required.

Merrill Lynch Arizona Municipal Bond Fund January 31, 2000
NOTES TO FINANCIAL STATEMENTS (continued)
(d) Security transactions and investment income--Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Interest income is recognized on the accrual basis. Discounts and market
premiums are amortized into interest income. Realized gains and losses on
security transactions are determined on the identified cost basis.
(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 future transactions and post-October
losses.
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. The Fund has also entered into a
Distribution Agreement and Distribution Plans with Merrill Lynch Funds
Distributor ("MLFD" or the "Distributor"), a divi- sion of Princeton Funds
Distributor, Inc. ("PFD"), which is a wholly-owned subsidiary of Merrill Lynch
Group, Inc.
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: .55% of the Fund's average daily net assets not exceeding $500
million; .525% of average daily net assets in excess of $500 million but not
exceeding $1 billion; and .50% of average daily net assets in excess of $1
billion.
Pursuant to the Distribution Plans 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 and distribution fees. The fees are accrued daily
and paid monthly at annual rates based upon the average daily net assets of the
shares as follows:
- --------------------------------------------------------------------------------
Account Distribution
Maintenance Fee Fee
- --------------------------------------------------------------------------------
Class B .............................. .25% .25%
Class C .............................. .25% .35%
Class D .............................. .10% --
- --------------------------------------------------------------------------------
Pursuant to a sub-agreement with the Distributor, Merrill Lynch, Pierce, Fenner
& Smith Incorporated ("MLPF&S"), a subsidiary of ML & Co., also provides account
maintenance and distribution services to the Fund. The ongoing account
maintenance fee compensates the Distributor and MLPF&S for providing account
maintenance services to Class B, Class C and Class D shareholders. The ongoing
distribution fee compensates the Distributor and MLPF&S for providing
shareholder and distribution-related services to Class B and Class C
shareholders.
For the six months ended January 31, 2000, MLFD earned underwriting discounts
and direct commissions and MLPF&S earned dealer concessions on sales of the
Fund's Class A and Class D Shares as follows:
- --------------------------------------------------------------------------------
MLFD MLPF&S
- --------------------------------------------------------------------------------
Class A ............................ $ 170 $1,188
Class D ............................ $ 97 $1,105
- --------------------------------------------------------------------------------
For the six months ended January 31, 2000, MLPF&S received contingent deferred
sales charges of $23,305 relating to transactions in Class B Shares.
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.
