[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 TaxAdvantage
Chairman of the Portfolio of Short-Term Investments Trust was
LETTER Board of the Fund marked by relative stability in short-term
TO OUR APPEARS HERE] financial markets. The markets expected that
SHAREHOLDERS Federal 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
Because of its relatively short average maturity, Treasury
TaxAdvantage Portfolio was able to take advantage of these higher
rates to improve the Fund's performance. The weighted average
maturity of the Portfolio was extended slightly, to 52 days at
the close of the reporting period.
The Treasury TaxAdvantage Portfolio continued to practice its
strict investment discipline, purchasing only direct obligations
of the U.S. Treasury. The portfolio seeks to maximize current
income to the extent consistent with preservation of capital and
maintenance of liquidity. This investment strategy is intended to
provide shareholders with dividends exempt from state and local
income tax.
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 TaxAdvantage 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.
As of February 28, 1997, the Institutional Class of the
Portfolio offered competitive yields: Its average monthly yield
was 4.93%, compared to 4.94% for IBC Money Fund
Averages(TM)-Government Only/Institutions Only. Its seven-day
yield was 4.95%, compared to 4.98% for IBC Money Fund
Averages(TM)-Government Only/Institutions Only.
The Portfolio continues to hold the highest credit quality
ratings given by two widely known credit-rating agencies: AAAm-G
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.
Net assets of the Institutional Class stood at $340.7 million
as of February 28, 1997.

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 TaxAdvantage 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,
/s/ CHARLES T. BAUER

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, with
the assets, liabilities and operations of each portfolio accounted for
separately. Information presented in these financial statements pertains only
to the Treasury TaxAdvantage Portfolio (the "Portfolio"). The Portfolio
consists of two different classes of shares: the Institutional Class and the
Private Investment Class. Matters affecting each class are voted on exclusively
by such shareholders. The Portfolio is a money market fund whose 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 the 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 these financial
statements and the reported amount 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 between 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 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 $250 million 0.20%
- ----------------------------------------
Over $250 million to $500 million 0.15%
- ----------------------------------------
Over $500 million 0.10%
- ----------------------------------------
</TABLE>
During the six months ended February 28, 1997, AIM voluntarily waived advisory
fees of $59,772 on the Portfolio and assumed expenses of $4,800.
The Fund has entered into a master distribution agreement with Fund Management
Company ("FMC") for the distribution of shares of the Institutional Class and
the Private Investment Class. The Company has also adopted a distribution plan
(the "Plan") pursuant to Rule 12b-1 under the 1940 Act with respect to the
Private Investment Class. The Plan provides that the Private Investment Class
may pay up to a 0.50% maximum annual rate of the Private Investment Class'
average daily net assets. Of this amount, the Fund may pay an asset-based sales
charge to FMC and the Portfolio may pay a service fee of 0.25%
8
<PAGE>
of the average daily net assets of the Private Investment 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. 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 the Private Investment Class.
During the six months ended February 28, 1997, the Private Investment Class
paid $68,802 as compensation under the Plan. FMC also waived fees of $68,802
for the same period.
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 $29,067 for such services.
The Portfolio, pursuant to a transfer agency and service agreement, has agreed
to pay AIM 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 $19,335 for such services.
Certain officers and trustees of the Fund are officers and directors of AIM,
FMC and AIFS.
The Portfolio paid legal fees of $3,192 for services rendered by Kramer,
Levin, Naftalis & Frankel as counsel to the Board of Trustees. A member of that
firm is a trustee of the Fund.
Shareholders' Meeting
An annual meeting of shareholders of the Fund was held on February 7, 1997 (the
"Meeting"). The following four items were approved by the 3,503,994,903 shares
of the Fund represented at the Meeting, with the following vote totals cast
with respect to each item:
(1) ELECTION OF TRUSTEES. At the Meeting, Messrs. Charles T. Bauer, Bruce L.
Crockett, Owen Daly II, Carl Frischling, Robert H. Graham, John F. Kroeger,
Lewis F. Pennock, Ian W. Robinson, and Louis S. Sklar were reelected to the
Board of Trustees of the Fund. 3,503,994,903 shares of the Fund voted for
each of the trustees, respectively, and no shares of the Fund withheld
authority, respectively.
(2) RATIFICATION OF INDEPENDENT ACCOUNTANTS. 3,503,994,903 shares of the
Fund voted for the ratification of the appointment of KPMG Peat Marwick LLP
as independent accountants for the Fund for the Fund's fiscal year ending
August 31, 1997. No shares of the Fund voted against the ratification of the
accountants and no shares of the Fund abstained.
(3) APPROVAL OF THE NEW INVESTMENT ADVISORY AGREEMENT. At the Meeting,
shareholders of the Portfolio were asked to approve a new Investment
Advisory Agreement (the "Agreement") between the Fund and A I M Advisors,
Inc. 260,840,561 shares of the Portfolio voted to approve the Agreement. No
shares of the Portfolio voted against the Agreement and no shares of the
Portfolio abstained.
(4) ELIMINATION OF THE FUNDAMENTAL INVESTMENT POLICY PROHIBITING OR
RESTRICTING INVESTMENTS IN OTHER INVESTMENT COMPANIES. 260,840,561 shares of
the Portfolio voted for the elimination of the fundamental investment
policy. No shares of the Portfolio voted against the elimination of the
fundamental investment policy and no shares of the Portfolio abstained.
NOTE 3-TRUSTEES' FEES
Trustees' fees represent remuneration paid or accrued to each trustee who is
not an "interested person" of AIM. The Fund may invest trustees' fees, if so
elected by a trustee, in mutual fund shares in accordance with a deferred
compensation plan.
