[AIM LOGO APPEARS HERE] Dear Shareholder:
[PHOTO of For the most part, the six-month period covered
Charles T. Bauer, by this report on the Treasury Portfolio of
Chairman of the Short-Term Investments Trust was marked by
LETTER Board of the Fund relative stability in short-term financial
TO OUR APPEARS HERE] markets. The markets expected that Federal
SHAREHOLDERS Reserve Board policy would be unchanged because
of prevailing evidence of an economy growing at a sustainable,
noninflationary rate.
Only during the last week of February 1997 did short-term
rates move significantly, rising as markets began to anticipate
higher short-term interest rates. That change in market
sentiment occurred primarily in response to statements by Fed
Chairman Alan Greenspan. In his semiannual testimony before
Congress, Greenspan spoke of the Open Market Committee's being
on "heightened" alert to the possibility of future inflation.
Greenspan's concern focused on the continued dramatic rise in
equity markets and on evidence that a strong job market could
ignite inflationary wage pressures.
YOUR INVESTMENT PORTFOLIO
The relatively stable market environment was not conducive to
strategic securities purchases. Portfolio management focused
largely on maintaining weighted average maturity at a desirable,
relatively short length while taking advantage of the high
yields and liquidity provided by a portfolio composed
exclusively of U.S. Treasury securities and repurchase
agreements secured by such obligations. Historically, the latter
have been among the highest-yielding instruments available to
the Portfolio. At the close of the reporting period, the
weighted average maturity of the portfolio was 26 days.
As shown in the table, use of a barbell portfolio structure
and emphasis on repurchase agreements produced very attractive
results. As of February 28, 1997, the Institutional Class of the
Portfolio outperformed its comparative indexes.
The Portfolio continues to hold the highest credit quality
ratings given by two widely known credit-rating agencies: AAAm
from Standard & Poor's Corporation and Aaa from Moody's
Investors Service, Inc. The ratings are historical and are based
on an analysis of the Portfolio's credit quality, composition,
management, and weekly portfolio reviews. The Institutional
Class of Treasury Portfolio ranked at the top in its Lipper
Category of institutional U.S. Treasury money market funds for
the one-, three-, five-, and ten-year periods ended February 28,
1997.

Net assets of the Institutional Class stood at $2.83 billion
as of February 28, 1997, up from $2.34 billion as of August 31,
1996.
The Treasury Portfolio seeks to maximize current income to the
extent consistent with preservation of capital and maintenance
of liquidity. It invests exclusively in U.S. Treasury securities
and repurchase agreements secured by such obligations.
Government securities, such as U.S. Treasury bills and bonds,
offer a high degree of safety and are guaranteed as to the
timely payment of principal if held to maturity. As with any
money market fund, an investment in Treasury Portfolio is
neither insured nor guaranteed by the U.S. government, the FDIC
or a bank, and there can be no assurance that the Portfolio will
be able to maintain a stable net asset value of $1.00 per share.
OUTLOOK FOR THE FUTURE
As the reporting period drew to a close, there was uncertainty
concerning the movement of interest rates. As mentioned above,
Fed Chairman Greenspan had told Congress the central bank was
vigilant about "potentially inflationary expansion." On the
other hand, information and data prepared in advance of the Open
Market Committee's March meeting reported temperate price
pressures in both the retail and manufacturing sectors, and
described the economy as expanding at "a relatively moderate
pace."
While this made an imminent interest rate hike seem unlikely,
it left markets alert to the possibility of a Fed tightening in
the near term. Treasury Portfolio management will remain
cautionary and will continue to manage the portfolio to provide
the maximum flexibility possible to respond to changes in the
short-term interest rate environment.
The prudence of that cautionary stance became evident on March
25, 1997, after the close of the reporting period. The Federal
Reserve Board's Open Market Committee raised the target federal
funds rate 25 basis points, a step that, by then, had become
widely anticipated.
AIM/INVESCO MERGER FINALIZED
We are pleased to announce that the merger of A I M Management
Group Inc. and INVESCO plc was concluded on February 28, 1997.
AIM is now part of one of the world's largest independent
investment management groups with approximately $160 billion in
assets under management.
The merger creates a company with the financial strength
necessary to meet your needs in an increasingly competitive
financial services environment, both in the United States and
worldwide. Though now under one holding company, AIM and INVESCO
will continue to operate as separate entities. Therefore, this
merger will not change the portfolio management, investment
style, or name of any of the AIM funds you own. The merger's
completion begins a new and promising era for AIM, one we
believe will yield exciting opportunities.
We are pleased to send you this report concerning your
investment. AIM is committed to customer service and to the
primary goals of safety, liquidity and yield in institutional
fund management. We are ready to respond to your comments about
this report and to any questions you may have. Please contact
one of our representatives at 800-659-1005 if we may be of
service.
Respectfully submitted,

NOTES TO FINANCIAL STATEMENTS
February 28, 1997
(Unaudited)
NOTE 1-SIGNIFICANT ACCOUNTING POLICIES
Short-Term Investments Trust (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 Delaware business trust
consisting of two different portfolios, each of which offers separate series of
shares: the Treasury Portfolio and the Treasury TaxAdvantage Portfolio.
Information presented in these financial statements pertains only to the
Treasury Portfolio (the "Portfolio"), with assets, liabilities and operations
of each portfolio being accounted for separately. The Portfolio consists of
five different classes of shares: the Institutional Class, the Private
Investment Class, the Personal Investment Class, the Cash Management Class and
the Resource Class. Matters affecting each class are voted on exclusively by
the shareholders of each class. The Portfolio's investment objective is the
maximization of current income to the extent consistent with the preservation
of capital and the maintenance of liquidity.
The following is a summary of significant accounting policies followed by the
Portfolio in the preparation of its financial statements. 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.
A. Security Valuations - The Portfolio invests only in securities which have
maturities of 397 days or less. The 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 and transfer agency expenses directly attributable
to a class of shares are charged to that class' operations. All other
expenses 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

assets of the Portfolio:

- ----------------------------------------
</TABLE>

<PAGE>
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,
1997, the Portfolio reimbursed AIM $44,822 for such services.
The Portfolio, pursuant to a transfer agency and service agreement, has agreed
to pay A I M Institutional Fund Services, Inc. ("AIFS") a fee for providing
transfer agent and shareholder services to the Portfolio. During the six months
ended February 28, 1997, the Portfolio paid AIFS $222,603 for such services.
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 and
the Resource Class of the Portfolio. The Plan provides that the Private
Investment Class, the Personal Investment Class, the Cash Management Class and
the Resource Class pay up to a 0.50%, 0.75%, 0.10%, 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 and the Personal Investment 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 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, 1997, the Private Investment Class, the Personal Investment
Class, the Cash Management Class and the Resource Class accrued for
compensation to FMC amounts of $555,275, $531,770, $323,917, and $117,747,
respectively, under the Plan. FMC waived fees of $746,484 for the same period.
Certain officers and trustees of the Trust are officers of AIM, FMC and AIFS.
During the six months ended February 28, 1997, the Portfolio paid legal fees
of $8,936 for services provided by Kramer, Levin, Naftalis & Frankel. A member
of that firm is a trustee of the Fund.
