WHAT AM I BEING ASKED TO VOTE ON?
You are asked to approve an amendment to the Master Investment Advisory
Agreement between A I M Advisors, Inc. ("AIM") and Short-Term Investments Co.,
on behalf of the Prime Portfolio.
Back to Questions
HOW DOES THE PROPOSED AMENDMENT ALTER THE CURRENT MASTER INVESTMENT ADVISORY
AGREEMENT?
It raises the fees payable to AIM for the investment advisory services it
provides. The fees for the Prime Portfolio have not changed since the fund's
inception in 1980. The Board has concluded that a change in the advisory fee is
appropriate in light of the increased complexity of managing the fund, the level
of services AIM provides, the performance of the fund and the fees charged for
similar funds by competing investment advisors.
In conjunction with the proposed increase in advisory fees, AIM will enter into
a contractual fee waiver with STIC, on behalf of Prime Portfolio, under which
AIM will agree to waive one-half of its advisory fee. The waiver will remain in
effect for one year from its effective date, which is expected to be January 1,
2002.
