[AIM LOGO APPEARS HERE] Dear Shareholder:
[PHOTO of As the fiscal year covered by this report
Charles T. Bauer, opened, financial markets were still in the
Chairman of the grip of the near-meltdown occasioned by 1998's
LETTER Board of The Fund Asian crises. The situation led the Federal
TO OUR APPEARS HERE] Reserve Board (the Fed) to reduce the short-
SHAREHOLDERS term federal funds target rate three times late
in 1998. These Fed moves were not motivated by
a slowdown in the U.S. economy; rather, they represented a
strenuous effort to reestablish liquidity in markets worldwide.
The U.S. economy continued to move ahead at a brisk pace,
exhibiting the unusual combination of strong growth coupled with
low inflation.
However, this scenario changed slightly as some monthly
economic indicators showed inflationary tendencies in certain
commodity prices. This and the unwinding of the 1998 global
crisis (evident in the stabilization of the foreign markets)
compelled the Fed to increase short-term interest rates twice
late in the fiscal year. The Fed increased the federal funds rate
25 basis points at both the June 30 and August 24 Federal Open
Market Committee meetings. On August 24, the Fed also increased
the discount rate by 25 basis points to 4.75%. Many investors
felt that part of the Fed's motivation in raising rates before
the fourth quarter was to stabilize the markets pre-emptively.
The Fed has committed to provide as much as $50 billion in cash
to banks at year-end, along with special liquidity facilities so
brokers can finance their inventories.
YOUR INVESTMENT PORTFOLIO
As of August 31, 1999, the portfolio's Personal Investment Class
remained competitive relative to its comparative indexes, as
shown in the table.
This record can be attributed to the portfolio's disciplined
approach of maintaining a laddered 60-day maximum maturity
schedule. This structure allows the portfolio to respond to
higher interest-rate levels more quickly than other funds with
longer maturity schedules, and it also allows the investor to
take advantage of higher yields through quarter-ends and other
volatile market periods. The portfolio's weighted average
maturity was maintained in the 15- to 25-day range during the
period. At the end of August 1999, the WAM stood at 23 days. The
portfolio will continue to maintain a relatively short WAM to
remain flexible in volatile interest-rate periods. Net assets of
the Personal Investment Class stood at $87.8 million as of August
31, 1999.

The portfolio continues to hold the highest credit-quality
ratings given by the two most widely known credit-rating
agencies: AAAm from Standard & Poor's and Aaa from Moody's. In
addition, the portfolio received the highest rating (AAA) from
Fitch IBCA. These historical ratings are based on an analysis of
the portfolio's credit quality, composition, management and
weekly portfolio reviews. With the addition of the AAA Fitch
rating, AIM has
(continued)
<PAGE>
become the largest multi-fund complex to have all its
institutional money market portfolios given the highest rating by
three nationally recognized ratings agencies.
The Prime Portfolio seeks to maximize current income to the
extent consistent with preservation of capital and maintenance of
liquidity. It invests in high-grade taxable money market
instruments with maturities of 60 days or fewer, including U.S.
government obligations, bank obligations, commercial paper and
selected repurchase-agreement securities. (An investment in a
money market fund is not insured or guaranteed by the Federal
Deposit Insurance Corporation or any other government agency.
Although a money market fund seeks to preserve the value of your
investment at $1.00 per share, it is possible to lose money by
investing in the fund.)
OUTLOOK FOR THE FUTURE
Although the U.S. gross domestic product growth rate fell from
2.3% to 1.6% at the end of the second quarter, the expected
annualized growth rate for the third quarter is 3.5%. The last
two Fed rate increases have so far had little effect on the U.S.
economy, which continues full steam ahead. With two more Fed
meetings scheduled in 1999 (November 16 and December 21),
investors are speculating about another Fed tightening. Liquidity
is the primary concern around the Y2K issue. Because no one knows
where the cash will be flowing by year-end, money managers are
dutifully estimating the anticipated high withdrawal volume from
financial institutions. Despite these concerns, another
tightening is still quite possible. Another increase would
position the federal funds target rate exactly where it was
before 1998's international crisis.
We are pleased to send you this annual report on your
investment. AIM is committed to the primary goals of safety,
liquidity and yield in institutional fund management. We are also
committed to customer service and are ready to respond to your
comments about this report. If you have any questions, please
contact one of our representatives at 800-659-1005. We are happy
to be of service.
Respectfully submitted,
/s/ CHARLES T. BAUER

NOTES TO FINANCIAL STATEMENTS
August 31, 1999
NOTE 1-SIGNIFICANT ACCOUNTING POLICIES
Short-Term Investments Co. (the "Fund") is registered under the Investment
Company Act of 1940, as amended, as an open-end series diversified management
investment company. The Fund is organized as a Maryland corporation consisting
of two different portfolios, each of which offers separate series of shares:
the Prime Portfolio and the Liquid Assets Portfolio. Information presented in
these financial statements pertains only to the Prime Portfolio (the
"Portfolio"), with the assets, liabilities and operations of each portfolio
accounted for separately. The Portfolio currently offers six different classes
of shares: the Institutional Class, the Private Investment Class, the Personal
Investment Class, the Cash Management Class, the Reserve Class and the Resource
Class. Matters affecting each class are voted on exclusively by the
shareholders of each class. The Portfolio is a money market fund whose
objective is the maximization of current income to the extent consistent with
the preservation of capital and the maintenance of liquidity.
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions
that affect the reported amounts of assets and liabilities at the date of the
financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates. The
following is a summary of the significant accounting policies followed by the
Portfolio in the preparation of its financial statements.
A. Security Valuations - The Portfolio's securities are valued on the basis of
amortized cost which approximates market value. This method values a
security at its cost on the date of purchase and thereafter assumes a
constant amortization to maturity of any discount or premium.
B. Securities Transactions, Investment Income and Distributions - Securities
transactions are accounted for on a trade date basis. Realized gains or
losses are computed on the basis of specific identification of the
securities sold. Interest income, adjusted for amortization of premiums and
discounts on investments, is accrued daily. Dividends to shareholders are
declared daily and are paid on the first business day of the following
month.
C. Federal Income Taxes - The Portfolio intends to comply with the requirements
of the Internal Revenue Code necessary to qualify as a regulated investment
company and, as such, will not be subject to federal income taxes on
otherwise taxable income (including net realized capital gains) which is
distributed to shareholders. Therefore, no provision for federal income
taxes is recorded in the financial statements.
D. Expenses - Distribution expenses directly attributable to a class of shares
are charged to that class' operations. All other expenses which are
attributable to more than one class are allocated among the classes.
NOTE 2-ADVISORY FEES AND OTHER TRANSACTIONS WITH AFFILIATES
The Fund has entered into a master investment advisory agreement with A I M
Advisors, Inc. ("AIM"). Under the terms of the master investment advisory
agreement, AIM receives a monthly fee with respect to the Portfolio calculated
by applying a monthly rate, based upon the following annual rates, to the
average daily net assets of the Portfolio:
<TABLE>
<CAPTION>
Net Assets RATE
- ----------------------------------------
<S> <C>
First $100 million 0.20%
- ----------------------------------------
Over $100 million to $200 million 0.15%
- ----------------------------------------
Over $200 million to $300 million 0.10%
- ----------------------------------------
Over $300 million to $1.5 billion 0.06%
- ----------------------------------------
Over $1.5 billion 0.05%
- ----------------------------------------
</TABLE>
The Fund, pursuant to a master administrative services agreement with AIM, has
agreed to pay AIM for certain administrative costs incurred in providing
accounting services to the Fund. During the year ended August 31, 1999, AIM was
paid $258,934 for such services.
The Fund, pursuant to a transfer agency and service agreement, has agreed to
pay A I M Fund Services, Inc. ("AFS") a fee for providing transfer agent and
shareholder services to the Fund. During the year ended August 31, 1999, AFS
was paid $903,145 for such services.

<PAGE>
Under the terms of a master distribution agreement between Fund Management
Company ("FMC") and the Fund, FMC acts as the exclusive distributor of the
Fund's shares. The Fund has adopted a master distribution plan (the "Plan")
pursuant to Rule 12b-1 under the 1940 Act with respect to the Private
Investment Class, the Personal Investment Class, the Cash Management Class, the
Reserve Class, and the Resource Class of the Portfolio. The Plan provides that
the Private Investment Class, the Personal Investment Class, the Cash
Management Class, the Reserve Class, and the Resource Class pay up to a 0.50%,
0.75%, 0.10%, 1.00%, and 0.20%, respectively, maximum annual rate of the
average daily net assets attributable to such class. Of this amount, the Fund
may pay an asset-based sales charge to FMC and the Fund may pay a service fee
of (a) 0.25% of the average daily net assets of each of the Private Investment
Class, Personal Investment Class, and the Reserve Class, (b) 0.10% of the
average daily net assets of the Cash Management Class and (c) 0.20% of the
average daily net assets of the Resource Class, to selected banks, broker-
dealers and other financial institutions who offer continuing personal
shareholder services to their customers who purchase and own shares of the
Private Investment Class, the Personal Investment Class, the Cash Management
Class, the Reserve Class, or the Resource Class. Any amounts not paid as a
service fee under such Plan would constitute an asset-based sales charge. The
Plan also imposes a cap on the total amount of sales charges, including asset-
based sales charges, that may be paid by the Portfolio with respect to each
class. During the year ended August 31, 1999, the Private Investment Class, the
Personal Investment Class, the Cash Management Class, the Reserve Class, and
the Resource Class paid $1,155,429, $758,574, $935,042, $940,270, and $226,673,
respectively, as compensation under the Plan. FMC waived fees of $1,675,069 for
the same period. Certain officers and directors of the Fund are officers of
AIM, FMC and AFS.
During the year ended August 31, 1999, the Portfolio paid legal fees of
$20,924 for services rendered by Kramer, Levin, Naftalis & Frankel LLP as
counsel to the Board of Directors. A member of that firm is a director of the
Fund.
NOTE 3-DIRECTORS' FEES
Directors' fees represent remuneration paid to directors who are not an
"interested person" of AIM. The Fund may invest directors' fees, if so elected
by a director, in mutual fund shares in accordance with a deferred compensation
plan.
NOTE 4-SHARE INFORMATION
Changes in shares outstanding during the year ended August 31, 1999 and 1998

INDEPENDENT AUDITORS' REPORT
To the Board of Trustees and Shareholders
Short-Term Investments Co.:
We have audited the accompanying statement of assets and liabilities of Prime
Portfolio (a series portfolio of Short-Term Investments Co.), including the
schedule of investments, as of August 31, 1999, and the related statement of
operations for the year then ended, the statements of changes in net assets for
each of the two years in the period then ended, and the financial highlights
for each of the five years in the period then ended. These financial statements
and financial highlights are the responsibility of the Fund's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits.
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and 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 as of
August 31, 1999 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, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of Prime
Portfolio as of August 31, 1999, the results of its operations for the year
then ended, the changes in its net assets for each of the two years in the
period then ended, and the financial highlights for each of the five years in
the period then ended, in conformity with generally accepted accounting
principles.
