Performance quoted is past performance and cannot guarantee comparable future results; current performance may be lower or higher. Investment return and principal value will vary so that you may have a gain or a loss when you sell shares.

Performance figures reflect reinvested distributions and changes in net asset value (NAV) and the effect of the maximum sales charge unless otherwise stated.

The contingent deferred sales charge (CDSC) on Class B shares declines from 5% beginning at the time of purchase to zero at the beginning of the seventh year. Performance shown at NAV does not include sales charges, which would have reduced the performance. Existing B share accounts will convert to Cash Reserves shares following the individual fund share aging schedule. Account holders should contact their financial adviser for more details on the aging schedule for their fund shares. Effective November 30, 2010, Class B shares will be closed to all additional investments, including additional investments by existing shareholders and new accounts.

The 360-day and 365-day yields represent the standard one-day yields for the fund. 30-day simple yields represent annualized results for the period, net of fees and expenses and exclude any realized capital gains or losses. Average annual total returns reflect reinvested distributions, net of expenses for the periods. The 7-day SEC yield more closely reflects the current earning of the fund than the total returns.

Class B shares of Invesco Money Market Fund are available but have no Nasdaq symbol.

^a The factor is the amount of income per share earned on securities held by the portfolio on a daily basis.

^b Weighted Average Maturity (WAM) - The length of time until the average security in a fund matures or will be redeemed by its issuer. It indicates a fixed income fund's sensitivity to interest rate changes. Longer average weighted maturity implies greater volatility in response to interest rate changes, while shorter average weighted maturity implies less volatility. WAM is calculated in days.

^c Weighted average life (WAL) - A measure of a money market fund's sensitivity to changes in credit spreads and other spread risks. Weighted average life, which is expressed in days, is calculated by summing the remaining maturity of each portfolio security or, when relevant, the number of days until the date of the next demand feature when the fund may receive payment of principal and interest, scaled by that security's share of the portfolio's total value, as measured by amortized cost. Weighted average life differs from weighted average maturity (WAM) in that the weighted average life calculation uses a variable-rate security's final maturity (or the date of the next demand feature); the weighted average maturity calculation uses the security's next interest rate reset date. Thus, weighted average life should always be equal to or greater than the weighted average maturity.

^d Market Value NAV: Net asset value (NAV) per share based on available market quotations of the portfolio's securities as provided by a third party pricing vendor as of the date stated. The mark to market valuation methodology includes marking all securities of the Portfolio. The Market Value NAV should not be viewed as indicative of future Market Value NAVs or the future performance of any of the Portfolios set forth above and should not be relied upon for purposes of making an investment decision. The Market Value NAV may change from day to day. Market Value NAVs are released at approximately 10:30 a.m. CT as of the date stated. The Market Value NAV does not reflect the price at which an investor may transact in shares of the Portfolios, and the forgoing should not be considered an offer to purchase or sell of any Portfolio at such price.
