(a)   Securities issued in reliance on Section (4) 2 or Rule 144A of the
      Securities Act of 1933. Rule 144A securities may be resold in transactions
      exempt from registration, normally to qualified institutional buyers. At
      October 31, 1999, these securities amounted to $764,335,145, representing
      24.1% of net assets on the Prime Portfolio, and $103,000,000, representing
      15.7% of net assets on the Trust Portfolio.

(b)   Funding agreements are illiquid securities subject to restrictions as to
      resale. These securities amounted to $50,000,000, representing 1.6% of net
      assets on the Prime Portfolio, and $10,000,000, representing 1.5% of net
      assets on the Trust Portfolio (see Note A to the financial statements).

(c)   Repurchase agreement which is terminable within 7 days.

(d)   All securities either mature or their interest rate changes in one year or
      less.

(e)   Variable Rate Demand Notes (VRDN) are instruments whose interest rates
      change on a specified date (such as a coupon date or interest payment
      date) or whose interest rates vary with changes in a designated base rate
      (such as the prime interest rate). These instruments are payable on demand
      and are secured by letters of credit or other credit support agreements
      from major banks. Periodic Put Bonds (PPB) are payable on demand
      quarterly, semi-annually or annually and their interest rates change less
      frequently than rates on Variable Rate Demand Notes.

NOTES TO FINANCIAL STATEMENTS
October 31, 1999 (unaudited)                     Alliance Institutional Reserves
================================================================================

NOTE A: Significant Accounting Policies

Alliance Institutional Reserves, Inc. (the "Fund") formerly ACM Institutional
Reserves, Inc., is registered under the Investment Company Act of 1940 as an
open-end investment company. On June 22, 1998 the creation of a second and third
class of shares, Class B and Class C shares, was approved by the Board of
Directors (with respect to the Prime, Government, Tax-Free and Treasury
Portfolios). The Fund operates as a series company currently consisting of five
Portfolios: Prime Portfolio, Government Portfolio, Tax-Free Portfolio, Trust
Portfolio and Treasury Portfolio. Each Portfolio is considered to be a separate
entity for financial reporting and tax purposes. The Prime, Government, Treasury
and Tax-Free Portfolios offer all three classes of shares. Each Portfolio
pursues its objectives by maintaining a portfolio of high-quality money market
securities all of which, at the time of investment, have remaining maturities of
397 days or less. The financial statements have been prepared in conformity with
generally accepted accounting principles which require management to make
certain estimates and assumptions that affect the reported amounts of assets and
liabilities in the financial statements and amounts of income and expenses
during the reporting period. Actual results could differ from those estimates.
The following is a summary of significant accounting policies followed by the
Fund.

1. Valuation of Securities

Securities in which the Fund invests are traded primarily in the
over-the-counter market and are valued at amortized cost, under which method a
portfolio instrument is valued at cost and any premium or discount is amortized
on a constant basis to maturity. Certain illiquid securities containing
unconditional par puts are also valued at amortized cost. Amortization of
premium is charged to income. Accretion of market discount is credited to
unrealized gain.

2. 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 any, to its
shareholders. Therefore, no provisions for federal income or excise taxes are
required.

3. Investment Income and Investment Transactions

Interest income is accrued daily. Investment transactions are recorded on the
date securities are purchased or sold. Investment gains and losses are
determined on the identified cost basis.

4. Dividends

The Fund declares dividends daily from net investment income and automatically
reinvests such dividends in additional shares at net asset value. Net realized
capital gains on investments, if any, are expected to be distributed near year
end. Dividends paid by Tax-Free Portfolio from net investment income for the six
months ended October 31, 1999 are exempt from federal income taxes. However,
certain shareholders may be subject to the alternative minimum tax.

5. Repurchase Agreements

It is the Fund's policy to take possession of securities as collateral under
repurchase agreements and to determine on a daily basis that the value of such
securities are sufficient to cover the value of the repurchase agreements.

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

NOTE B: Advisory Fee and Transactions with an Affiliate of the Adviser

Under the terms of an investment advisory agreement, the Fund pays Alliance
Capital Management L.P., (the "Adviser"), an advisory fee at the annual rate of
 .20% of average daily net assets for the Prime, Government, Tax-Free and
Treasury Portfolios and .45% of average daily net assets for the Trust
Portfolio. For the six months ended October 31, 1999, the Adviser has agreed to
reimburse each of the Portfolios to the extent necessary to limit total
operating expenses on an annual basis to a certain limit (excluding taxes,
brokerage, interest and, where permitted, extraordinary expenses). For the six
months ended October 31, 1999, reimbursement was $428,288, $193,561, $230,727,
$85,682 and $121,722 for the Prime, Government, Tax-Free, Trust and Treasury
Portfolios, respectively.

Each Portfolio compensates Alliance Fund Services, Inc., a wholly-owned
subsidiary of the Adviser, under a Transfer Agency Agreement for providing
personnel and facilities to perform transfer agency services. Such compensation
for the Prime, Government, Tax-Free, Trust and Treasury Portfolios was $9,000
per Portfolio, for the six months ended October 31, 1999.

For the six months ended October 31, 1999, the Fund's expenses were reduced by
$488, $147, $794 and $207 for the Prime, Government, Trust and Treasury
Portfolios, respectively under an expense offset arrangement with Alliance Fund
Services.


                                                                              21

                                                 Alliance Institutional Reserves
================================================================================

NOTE C: Distribution Agreement

The Fund has adopted a Distribution Agreement (the "Agreement") which includes
for each Portfolio except the Trust Portfolio, a distribution plan pursuant to
Rule 12b-1 under the Investment Company Act of 1940. Under the Agreement, the
Fund pays distribution and servicing fees to the Distributor at an annual rate
of .10 of 1% of the aggregate average daily net assets attributable to Class B
shares of the Prime, Government, Treasury and Tax-Free Portfolios and .25 of 1%
of the aggregate average daily net assets attributable to Class C shares of the
Prime, Government, Treasury and Tax-Free Portfolios. There are no distribution
and servicing fees on the Class A shares. Such fees are accrued daily and paid
monthly. The Agreement provides that the Distributor will use such payments in
their entirety for distribution assistance and promotional activities. The
Agreement also provides that the Adviser may use its own resources to finance
the distribution of the Fund's shares.

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

NOTE D: Investment Transactions

At October 31, 1999, the cost of investments for federal income tax purposes was
the same as the cost for financial reporting purposes for all Portfolios. For
federal income tax purposes, the Prime Portfolio had a capital loss carryforward
available to offset future gains at April 30, 1999 of $136,809, of which $71,055
expires in 2003, $40,007 in 2004 and $25,747 in the year 2005; the Government
Portfolio had a capital loss carryforward of $130,160, of which $151 expires in
2000, $9,174 in 2001, $51,091 in 2002, $23,230 in 2003, $30,512 in 2004 and
$16,002 in the year 2005; the Tax-Free Portfolio had a capital loss carryforward
of $83,495, of which $6,110 expires in 2002, $76,925 in 2004, $400 in 2005 and
$60 in the year 2006; the Trust Portfolio had a capital loss carryforward of

      day of the period. Total investment return calculated for a period of less
      than one year is not annualized.

(c)   Annualized.

(d)   Commencement of distribution.

CHANGE IN INDEPENDENT ACCOUNTANT                 Alliance Institutional Reserves
================================================================================

On July 13, 1999, McGladrey & Pullen, LLP ("McGladrey") notified the Fund of its
intention to resign as independent auditors of the Fund pursuant to an agreement
by PricewaterhouseCoopers LLP ("PwC") to acquire McGladrey's investment company
practice. The McGladrey partners and professionals serving the Fund at the time
of the acquisition joined PwC.

The reports of McGladrey on the financial statements of the Fund during the past
two fiscal years contained no adverse opinion or disclaimer of opinion, and were
not qualified or modified as to uncertainty, audit scope or accounting
principles.

In connection with its audits for the two most recent fiscal years and through
July 13, 1999, there were no disagreements with McGladrey on any matter of
accounting principle or practices, financial statement disclosure, or auditing
scope or procedure, which disagreements, if not resolved to the satisfaction of
McGladrey would have caused it to make reference to the subject matter of
disagreement in connection with its report.

On July 13, 1999, the Fund, with the approval of its Board of Trustees and its
Audit Committee, engaged PwC as its independent auditors.
