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 the same.

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

Expense Example - Class A, A2 And Y Invesco Limited Maturity Treasury Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Class A	325	484	657	1,157
Class A2	166	306	459	902
Class Y	51	160	280	628

Portfolio Turnover.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 138% of the average value of its portfolio.

Principal Investment Strategies of the Fund

The Fund invests under normal circumstances at least 80% of its net assets (plus any borrowings for investment purposes) in direct obligations of the U.S. Treasury, including bills, notes and bonds. The Fund invests principally in short-term U.S. Treasury notes with remaining maturities of five years or less at the time of purchase.

                   In complying with the 80% investment requirement, the Fund may include synthetic securities that have economic characteristics similar to the Fund’s direct investments that are counted toward the 80% investment requirement.

                   The Fund may invest in interest rate futures to gain or reduce its exposure to interest rates. An interest rate futures contract is an exchange-traded contact in which the specified underlying security is either an interest-bearing fixed income security or an inter-bank deposit. Interest rate futures are based off an underlying security which is a debt obligation and moves in value as interest rates change.

                   The Fund intends to maintain an average weighted maturity of three years or less.

                   The portfolio managers utilize an appropriate benchmark index in structuring the portfolio. The portfolio managers then decide on risk factors to use in managing the Fund relative to that benchmark. In doing so, the portfolio managers consider recommendations from a team of independent specialists in positioning the Fund to generate alpha (specific factors affecting the return on investments in excess of the benchmark). The portfolio managers generally rely upon a different team of specialists for trade execution and for assistance in determining the most efficient way (in terms of cost-efficiency and security selection) to implement those recommendations. Although a variety of specialists provide input in the management of the Fund, the portfolio managers retain responsibility for ensuring the Fund is positioned appropriately in terms of risk exposures and position sizes. The portfolio managers rely on the specialists for adjusting the Fund’s risk exposures and security selection. Decisions to purchase or sell securities are determined by the relative value considerations of the investment professionals that factor in economic and credit-related fundamentals, market supply and demand, market dislocations and situation-specific opportunities. The purchase or sale of securities may be related to a decision to alter the Fund’s macro risk exposure (e.g., duration, yield, curve positioning or sector exposure), a need to limit or reduce the Fund’s exposure to a particular security or issuer, degradation of an issuer’s credit quality, or general liquidity needs of the Fund.

                   In attempting to meet its investment objective, the Fund engages in active and frequent trading of portfolio securities.

Principal Risks of Investing in the Fund

As with any mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are:

                   Active Trading Risk. The Fund engages in frequent trading of portfolio securities. Active trading results in added expenses and may result in a lower return and increased tax liability.

                   Derivatives Risk. The performance of derivative instruments is tied to the performance of an underlying currency, security, index or other instrument. In addition to risks relating to their underlying instruments, the use of derivatives may include other, possibly greater, risks. Derivatives involve costs, may be volatile, and may involve a small initial investment relative to the risk assumed. Risks associated with the use of derivatives may include counterparty, leverage, correlation, liquidity, tax, market, interest rate and management risks. Derivatives may also be more difficult to purchase, sell or value than other investments. The Fund may lose more than the cash amount invested on investments in derivatives. Investors should bear in mind that, while the Fund intends to use derivative strategies, it is not obligated to actively engage in these transactions, generally or in any particular kind of derivative, if the investment manager elects not to do so due to availability, cost, market conditions or other factors.

                    Management Risk. The investment techniques and risk analysis used by the Fund’s portfolio managers may not produce the desired results.

                   Market Risk. The prices of and the income generated by the Fund’s securities may decline in response to, among other things, investor sentiment, general economic and market conditions, regional or global instability, and currency and interest rate fluctuations.

                   Reinvestment Risk. Reinvestment risk is the risk that a bond’s cash flows (coupon income and principal repayment) will be reinvested at an interest rate below that on the original bond.

                   Synthetic Securities Risk. Fluctuations in the values of synthetic securities may not correlate perfectly with the instruments they are designed to replicate. Synthetic securities may be subject to interest rate changes, market price fluctuations, counterparty risk and liquidity risk.
