MARKET OVERVIEW

Much like the market trend established in early 1996, the municipal bond market
returned inconsistent performance in the first quarter of 1997. After posting
strong returns through early February, the bond market became weaker as
investors grew more cautious about the strength of the economy and its potential
effect on the stock market. Confirming this strong economic growth outlook, in
early March, the Federal Reserve Board raised its benchmark Federal funds rate
by one quarter of one percent, or 25 basis points, in an effort to contain
present and future inflationary pressures. Volatility continued through the
remainder of the first quarter. At this writing, it is still widely believed by
the investment community that the Federal Reserve will need to increase rates at
least one more time in the near future to complete the current round of money
supply tightening.

THE MUNICIPAL BOND MARKET

One theme that we have discussed over the last several years has been the
importance of various technical factors affecting the relative value of
municipal bonds versus taxable bonds. Since late 1995, municipal bonds have been
trading at inexpensive prices when compared to their fully taxable counterparts.
This was due to the threat of "tax reform" during the last election. However,
now that the election and the tax reform debate seem well behind us, we expect
that municipal bond prices will improve relative to their taxable counterparts.
The volume of new issues of municipal securities accelerated in the first
quarter of 1997 for the first time in years. This trend is attributable to an
increase in voter authorized state and local government debt and a low interest
rate environment. As a result of this influx of new issues, municipal bonds
currently offer excellent value relative to other fixed-income investments,
especially when compared on a tax-adjusted basis.

Credit ratings of municipal issuers improved as state and local governments
benefited from a robust economy which resulted in higher-than-expected tax
receipts. Many large states such as California, New York, Massachusetts and
Michigan are in their best fiscal condition in years. In most cases, many of
these states have built up substantial "rainy day" funds to cushion against
future economic downturns. These

                                                                               1

                                            ACM MUNICIPAL SECURITIES INCOME FUND
- --------------------------------------------------------------------------------

funds will be critical in maintaining strong fiscal performance, especially if
economic growth slows and big budget items such as Medicaid costs begin to rise.
For state and local governments, the continuation of tax reduction programs and
the likely continuation of anti-tax sentiment, will be constraining factors in
maintaining budgetary balances in the next couple of years. The recent proposal
by the State of New Jersey to close a budget gap by selling a $2.75 billion
pension funding bond may be a precursor of future budgetary actions in other
states where large tax cuts have severely cut the revenue base. This phenomenon
could result in weakening credit quality of issuers who pursue these types of
stop-gap measures.

INVESTMENT STRATEGY

The first quarter volatility in the bond market once again provided your
portfolio managers with an opportunity to capture higher incremental after-tax
yield and to further improve overall call protection in the Fund's portfolios.
At Alliance, we continue to believe that long-term interest rates will decline
modestly over the next several years, and that market weakness provides an
opportunity for us to purchase quality securities at advantageous prices. To
make room for these attractive new issues, we continue to sell lower-coupon
bonds with call protection of less than 10 years. We also continue to sell bonds
that have been "pre-refunded" by their issuers and have realized their maximum
price appreciation potential relative to other investment opportunities.

The overall theme of our municipal bond portfolio strategy continues to be one
of active management in terms of the performance factors we can control (namely
the securities owned in your portfolios) without attempting to manage the
portfolios for those factors that are out of our control (such as the future
direction of interest rates). This strategy is centered on selecting securities
with price appreciation potential, either through credit improvements,
structural features or technical factors. By continuing to keep a "buy low, sell
high" philosophy as part of our strategy, we expect to once again post strong
performance relative to our peers in the mutual fund industry.

MARKET OUTLOOK

Barring any unforeseen drama in the global financial markets, we expect 1997 to
be a calm year for municipal bond investors. Municipal bond prices should
continue to trade in a fairly narrow range and yields will most likely peak on
or around current levels in the near future. Any increase in short-term rates on
the part of the Federal Reserve should be viewed as a positive for long-term
fixed income investors because such action will help curb inflationary pressures
in the economy. Finally, we believe that the municipal bond market offers
excellent value at current prices, especially on a tax-adjusted basis.

We appreciate your investment in ACM Municipal Securities Income Fund and look
forward to reporting to you again in the coming period.

Sincerely,

/s/ John D. Carifa

ACM Municipal Securities Income Fund, Inc. (the "Fund"), was incorporated in the
state of Maryland on February 11, 1993 and is registered under the Investment
Company Act of 1940 as a diversified, closed-end management investment company.
The following is a summary of significant accounting policies followed by the
Fund.

1. Security Valuation

The Fund values municipal securities at fair value based on prices provided by a
recognized pricing service which uses information with respect to transactions
in bonds, quotations from bond dealers, market transactions in comparable
securities and various relationships between securities in determining values.

If market quotations are not readily available from such pricing service, a
municipal security is valued by appraisal at its fair value as determined in
good faith by the Fund's Adviser under procedures established by the Fund's
Board of Directors. Short-term securities which mature in 60 days or less are
valued at amortized cost, which approximates market value unless this method
does not represent fair market value.

2. Organization Expenses

Organization expenses of approximately $60,000 have been deferred and are being
amortized on a straight-line basis through May, 1998.

- --------------------------------------------------------------------------------

3. Taxes

It is the Fund's policy to meet the requirements of the Internal Revenue Code
applicable to regulated investment companies and to distribute all of its
investment company taxable income and net realized gains, if applicable, to
shareholders. Therefore, no provisions for federal income or excise taxes are
required.

4. Investment Income and Investment Transactions

Interest income is accrued daily. Investment transactions are accounted for on
the date the securities are purchased or sold. Investment gains and losses are
determined on the identified cost basis. The Fund amortizes premiums and
accretes discounts as adjustments to interest income.

5. Dividends and Distributions

Dividends and distributions to shareholders are recorded on the ex-dividend date
and are determined in accordance with income tax regulations.

For federal income tax purposes, the Fund's distributions of income and capital
gains are subject to recharacterization, which may include a tax return of
capital, at the end of the year to reflect the final investment results for that
year.

- --------------------------------------------------------------------------------

NOTE B: Advisory and Administrative Fees

Under the terms of the investment advisory agreement, the Fund pays Alliance
Capital Management L.P., (the "Adviser") an advisory fee equal to an annualized
rate of .50 of 1% of the average weekly net assets of the Fund during the month.

On November 28, 1995, the Fund entered into a Shareholder Inquiry Agency
Agreement with Alliance Fund Services, Inc. ("AFS"), an affiliate of the
Adviser, whereby the Fund reimburses AFS for costs relating to servicing phone
inquiries for the Fund. During the six months ended April 30, 1997 there was no
reimbursement paid to AFS.

Under the terms of the Administration Agreement, the Fund pays Alliance Capital
Management L.P. (the "Administrator") an administration fee equal to an
annualized rate of .15 of 1% of the average weekly net assets of the Fund during
the month. The Administrator has engaged Prudential Mutual Fund Management, Inc.
(the "Sub-Administrator") to act as Sub-Administrator. The Administrator, out of
its own assets, will pay the Sub-Administrator a monthly fee equal to an
annualized rate of .10 of 1% of the Fund's average weekly net assets. The Sub-
Administrator prepares financial and regulatory reports for the Fund and
provides other clerical services.

                                                                               9

(a) Commencement of operations.
(b) Net of offering costs of $.09.
(c) Total investment return is calculated assuming a purchase of common stock on
the opening of the first day and a sale on the closing of the last day of the
period reported. Dividends and distributions, if any, are assumed for purposes
of this calculation, to be reinvested at prices obtained under the Fund's
dividend reinvestment plan. Generally, total investment return based on net
asset value will be higher than total investment return based on market value in
periods where there is an increase in the discount or a decrease in the premium
of the market value to net asset value from the beginning to the end of such
periods. Conversely, total investment return based on net asset value will be
lower than total investment return based on market value in years where there is
a decrease in the discount or an increase in the premium of the market value to
the net asset value from the beginning to the end of such periods. Total
investment return calculated for a period of less than one year is not
annualized. (d) The expense ratio and net investment income ratio do not reflect
the effect of dividend and distribution payments to Preferred Stock
shareholders. (e) Annualized.
