Invesco Advisers, Inc. (Invesco or the Adviser) has contractually agreed to waive advisory fees and/or reimburse expenses to the extent necessary to limit Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement (excluding certain items discussed in the SAI) of Institutional Class shares to 0.18% of the Fund’s average daily net assets (the “expense limit”). Unless Invesco continues the fee waiver agreement, it will terminate on December 31, 2016. During its term, the fee waiver agreement cannot be terminated or amended to increase the expense limit without approval of the Board of Trustees.

Example. This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain equal to the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement in the first year and the Total Annual Fund Operating Expenses thereafter.

Although your actual costs may be higher or lower, based on these assumptions your costs would be:


	1 Year		3 Years		5 Years		10 Years

Effective June 1, 2016, the following information replaces in its entirety the information appearing under the heading “Hypothetical Investment and Expense Information”:

“In connection with the final settlement reached between Invesco and certain of its affiliates with certain regulators, including the New York Attorney General’s Office, the SEC and the Colorado Attorney General’s Office (the settlement) arising out of certain market timing and unfair pricing allegations made against Invesco and certain of its affiliates, Invesco and certain of its affiliates agreed, among other things, to disclose certain hypothetical information regarding investment and expense information to Fund shareholders. The chart below is intended to reflect the annual and cumulative impact of the Fund’s expenses, including investment advisory fees and other Fund costs, on the Fund’s returns over a 10-year period. The example reflects the following:

•

You invest $10,000 in the fund and hold it for the entire 10-year period;

•

Your investment has a 5% return before expenses each year; and

•

Liquid Assets Portfolio, STIC Prime Portfolio, Treasury Portfolio, Government TaxAdvantage Portfolio and Tax-Free Cash Reserve Portfiolio’s current annual expense ratio includes any applicable contractual fee waiver or expense reimbursement for the period committed.

There is no assurance that the annual expense ratio will be the expense ratio for the Fund classes for any of the years shown. This is only a hypothetical presentation made to illustrate what expenses and returns would be under the above scenarios; your actual returns and expenses are likely to differ (higher or lower) from those shown below.

Invesco Advisers, Inc. (Invesco or the Adviser) has contractually agreed to waive advisory fees and/or reimburse expenses to the extent necessary to limit Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement (excluding certain items discussed in the SAI) of Reserve Class shares to 1.07% of the Fund’s average daily net assets (the “expense limit”). Unless Invesco continues the fee waiver agreement, it will terminate on December 31, 2016. During its term, the fee waiver agreement cannot be terminated or amended to increase the expense limit without approval of the Board of Trustees.

Example. This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

Although your actual costs may be higher or lower, based on these assumptions your costs would be:

•

Each Portfolio’s current annual expense ratio includes any applicable contractual fee waiver or expense reimbursement for the period committed.
