[AIM LOGO APPEARS HERE] Dear Shareholder:
[PHOTO of As the six-month period covered by this report
Charles T. Bauer, was closing, the U.S. economy continued to move
Chairman of the ahead at a brisk pace. During the final quarter
LETTER Board of the Fund of 1998, the economy grew at its fastest rate in
TO OUR APPEARS HERE] two and a half years. Total gross domestic
SHAREHOLDERS product (GDP) growth for 1998 was 3.9%.
There was a different story overseas. Throughout the second half
of 1998, the global economy continued to experience economic
turmoil, financial instability and increased credit concerns.
Certain regions, particularly Asia, Russia and Latin America,
remained in a severe downturn.
As a result of this global meltdown, the U.S. Federal Open
Market Committee of the Federal Reserve Board (the Fed) reduced
the federal funds rate from 5.5% to 4.75% in three steps between
September and November. The discount rate was also reduced from 5%
to 4.5%. Interest rates were lowered, not to stimulate an already
strong U.S. economy, but to minimize the impact of the
international economic crises upon the U.S. economy and to
decrease volatility and calm the financial markets. In the United
States and Europe, financial markets were very volatile, but the
underlying economies continued surprisingly strong growth.
The yield on the one-year Treasury bill, which was as high as
5.32% in early July, dropped to 4.37% in early December as an
increase in the one-year Treasury bill's price caused its yield to
decline. The price increase was a result of investors' demand for
Treasuries in a "flight to quality" environment resulting from the
international crises and credit concerns.
YOUR INVESTMENT PORTFOLIO
Through a combination of short-term cash management vehicles and
selective use of a longer maturity schedule for higher yields, the
Portfolio continued to provide attractive returns. Weighted
average maturity (WAM) was held at a moderate length for much of
the period due to the concern derived from increased volatility
experienced in the fourth quarter of 1998. The WAM remained in the
20- to 35-day range. At the close of the period, the WAM was 34
days. The Portfolio will continue to maintain a relatively short
maturity structure to take advantage of any sudden rise in market
yields.
Using this strategy, the Private Investment Class of the
Portfolio offered highly competitive yield as of February 28,
1999, as shown in the table.
The Portfolio holds the highest credit quality ratings given by
three widely known credit-rating agencies. It continues to be
rated AAAm by Standard & Poor's Corporation and Aaa by Moody's
Investors Service, Inc. In addition, shortly after the reporting
period closed, the Portfolio received the highest rating, AAA,
granted by Fitch IBCA. These ratings are historical and 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

became the only multi-fund complex to have all of its
institutional money market portfolios given the highest rating by
three different rating agencies.
Net assets of the Private Investment Class stood at $229.78
million at the close of the reporting period, up significantly
from $70.06 million six months earlier.
The Liquid Assets Portfolio invests solely in securities rated
"First Tier" as defined in Rule 2a-7 under the Investment Company
Act of 1940. Its objective is to provide as high a level of
current income as is consistent with the preservation of capital
and liquidity. Using a barbell maturity structure, portfolio
management emphasizes superior credit quality in purchasing money
market securities such as 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 investing in the fund.
OUTLOOK FOR THE FUTURE
Statistics released shortly after the close of the reporting
period showed that employment gains have exceeded expectations and
wage inflation has been virtually non-existent. This caused
interest rates to drop, another indication the U.S. economy
continues to benefit from the unusual combination of strong growth
and low inflation.
As 1998 ended, there was speculation the Fed might decrease
interest rates even more. However, this view changed abruptly with
the release of stronger-than-expected adjusted December and
January economic numbers during the first quarter of 1999. These
numbers and other factors led many to speculate about the Fed
changing course and raising short-term rates again. We believe it
is unlikely such a move would be made soon because inflation
remains negligible despite robust economic growth. For the 12
months ended February 1999, producer prices were up just 0.5%, and
prices for intermediate goods actually fell during February 1999.
Retail sales growth and other economic indicators led to estimated
annualized GDP growth of 4.6% for the first quarter of 1999.

(comprised of eligible debt obligations) entitling the Portfolio to receive
variable rate interest. The Fund has the right, upon seven calendar days'
notice to the trustee, to put its certificates to the trust at par value
plus accrued interest. Because variable rate trust certificates involve a
trust and a third party put feature, they involve complexities and
potential risks that may not be present where the debt obligation is owned
directly. Rate shown is the rate in effect on 02/28/99.
(d) The Portfolio may demand prepayment of notes purchased under the Master
Note Purchase Agreement upon seven business days' notice. Interest rates on
master notes are redetermined periodically. Rate shown is the rate in

interest in joint repurchase agreements, is taken into possession by the
Portfolio upon entering into the repurchase agreement. The collateral is
marked to market daily to ensure its market value is at least 102% of the
sales price of the repurchase agreement. The investments in some repurchase
agreements are through participation in joint accounts with other mutual
funds, private accounts and certain non-registered investment companies
managed by the investment advisor or its affiliates.

NOTES TO FINANCIAL STATEMENTS
February 28, 1999
(Unaudited)
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 Liquid Assets 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 Cash Management Class, the Private
Investment Class, the Personal Investment 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 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. The Portfolio has a capital
loss carryforward of $629,465 (which may be carried forward to offset future
taxable gains, if any) which expires, if not previously utilized, through
the year 2004. The Portfolio cannot distribute capital gains to shareholders
until the tax loss carryforwards have been utilized.
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 at the
annual rate of 0.15% of the average daily net assets of the Portfolio. During
the six months ended February 28, 1999, AIM voluntarily waived fees of
$2,669,700.
The Portfolio, pursuant to a master administrative services agreement with
AIM, has agreed to reimburse AIM for certain costs incurred in providing
accounting services to the Portfolio. During the six months ended February 28,
1999, the Portfolio reimbursed AIM $55,010 for such services.
The Portfolio, 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 Portfolio. During the six months ended February 28,
1999, the Portfolio paid AFS $281,066 for such services.
13
<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 six months ended February 28, 1999, the Private Investment
Class, the Cash Management Class, and the Resource Class paid $204,189,
$269,430, and $62,111, respectively, as compensation under the Plan. FMC waived
fees of $203,484 for the same period. Certain officers and directors of the
Fund are officers of AIM, FMC and AFS.
During the six months ended February 28, 1999, the Portfolio paid legal fees
of $53,645 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 or accrued to each director who is
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 six months ended February 28, 1999 and
