Invesco U.S. Managed Volatility Fund

Derivatives Risk. The value of a derivative instrument depends largely on (and is derived from) the value of an underlying security, currency, commodity, interest rate, index or other asset (each referred to as an underlying asset). In addition to risks relating to the underlying assets, the use of derivatives may include other, possibly greater, risks, including counterparty, leverage and liquidity risks. Counterparty risk is the risk that the counterparty to the derivative contract will default on its obligation to pay the Fund the amount owed or otherwise perform under the derivative contract. Derivatives create leverage risk because they do not require payment up front equal to the economic exposure created by owning the derivative. As a result, an adverse change in the value of the underlying asset could result in the Fund sustaining a loss that is substantially greater than the amount invested in the derivative, which may make the Fund's returns more volatile and increase the risk of loss. Derivative instruments may also be less liquid than more traditional investments and the Fund may be unable to sell or close out its derivative positions at a desirable time or price. This risk may be more acute under adverse market conditions, during which the Fund may be most in need of liquidating its derivative positions. Derivatives may also be harder to value, less tax efficient and subject to changing government regulation that could impact the Fund's ability to use certain derivatives or their cost. Also, derivatives used for hedging or to gain or limit exposure to a particular market segment may not provide the expected benefits, particularly during adverse market conditions.

Indexing Risk. Certain portions of the Fund's assets are managed pursuant to an indexing approach (Indexed Assets) and, therefore, the adverse performance of a particular security necessarily will not result in the elimination of the security from the Indexed Assets. Ordinarily, the Fund will not sell portfolio securities of the Indexed Assets except to reflect additions or deletions of the securities that comprise the index the Fund seeks to track with respect to the Indexed Assets (Underlying Index), or as may be necessary to raise cash to pay Fund shareholders who sell Fund shares. As such, the Indexed Assets, and therefore the Fund, will be negatively affected by declines in the securities represented by the Underlying Index. Also, there is no guarantee that the Fund will be able to correlate the performance of the Indexed Assets with that of the Underlying Index.

Management Risk. The Fund is actively managed and depends heavily on the Adviser's judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund's portfolio. The Fund could experience losses if these judgments prove to be incorrect. There is no guarantee that the portfolio manager's stock selection process will produce lower volatility than the broader markets in which the Fund invests. In addition, the Fund's investment strategy to seek lower volatility may cause the Fund to underperform the broader markets in which the Fund invests during market rallies. Such underperformance could be significant during sudden or significant market rallies. Additionally, legislative, regulatory, or tax developments may adversely affect management of the Fund and, therefore, the ability of the Fund to achieve its investment objective.

Market Risk. The market values of the Fund's investments, and therefore the value of the Fund's shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. Individual stock prices tend to go up and down more dramatically than those of certain other types of investments, such as bonds. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.

Non-Correlation Risk. The return of the Fund's assets managed pursuant to an indexing approach (Indexed Assets) may not match the return of the index the Fund seeks to track with respect to the Indexed Assets (Underlying Index) for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing securities holdings to reflect changes in the Underlying Index. In addition, the performance of the Indexed Assets and the Underlying Index may vary due to asset valuation differences and differences between the Indexed Assets and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Sampling Risk. The Fund's use of a sampling methodology with respect to assets managed pursuant to an indexing approach (Indexed Assets) may result in the Indexed Assets including a smaller number of securities than are in the index the Fund seeks to track with respect to the Indexed Assets (Underlying Index), and in the Indexed Assets including securities that are not included in the Underlying Index. As a result, an adverse development to an issuer of securities included in the Indexed Assets could result in a greater decline in the Fund's NAV than would be the case if all of the securities in the Underlying Index were included in the Indexed Assets. The Fund's use of a sampling methodology may also include the risk that the Indexed Assets may not track the return of the Underlying Index as well as they would have if the Indexed Assets included all of the securities in the Underlying Index. To the extent the assets in the Indexed Assets are smaller, these risks will be greater.

Short Position Risk. Because the Fund's potential loss on a short position arises from increases in the value of the asset sold short, the Fund will incur a loss on a short position, which is theoretically unlimited, if the price of the asset sold short increases from the short sale price. The counterparty to a short position or other market factors may prevent the Fund from closing out a short position at a desirable time or price and may reduce or eliminate any gain or result in a loss. In a rising market, the Fund's short positions will cause the Fund to underperform the overall market and its peers that do not engage in shorting. If the Fund holds both long and short positions, and both positions decline simultaneously, the short positions will not provide any buffer (hedge) from declines in value of the Fund's long positions. Certain types of short positions involve leverage, which may exaggerate any losses, potentially more than the actual cost of the investment, and will increase the volatility of the Fund's returns.

Volatility Risk. Although the Fund's investment strategy seeks to not exceed a target volatility level (the threshold volatility level), certain of the Fund's investments may appreciate or decrease significantly in value over short periods of time. This may cause the Fund's net asset value per share to experience significant increases or declines in value over short periods of time.

Volatility Management Risk. The Adviser's strategy for managing portfolio volatility may not produce the desired result and there can be no guarantee that the Fund will stay below a target volatility level (the threshold volatility level). Additionally, maintenance of the threshold volatility level will not ensure that the Fund will deliver competitive returns. The use of derivatives in connection with the Fund's managed volatility strategy may expose the Fund to losses (some of which may be sudden) that it would not have otherwise been exposed to if it had only invested directly in equity and/or fixed income securities. Efforts to manage the Fund's volatility could limit the Fund's gains in rising markets and may expose the Fund to costs to which it would otherwise not have been exposed. The Adviser uses a combination of proprietary and third-party systems and risk models to help it estimate the Fund's expected volatility, which may perform differently than expected and may negatively affect performance and the ability of the Fund to maintain its volatility at or below its threshold volatility level.
