Invesco MSCI World SRI Index Portfolio

Risks of the Underlying Holding

Because the fund operates as a passively managed index fund, adverse performance of a particular stock ordinarily will not result in its elimination from the fund's portfolio. Ordinarily, the Adviser will not sell the fund's portfolio securities except to reflect changes in the stocks that comprise the Index, or as may be necessary to raise cash to pay fund shareholders who sell fund shares.

The Fund's value may be affected by changes in the stock markets. Stock markets may experience significant short-term volatility and may fall or rise sharply at times. Adverse events in any part of the equity or fixed-income markets may have unexpected negative effects on other market segments. Different stock markets may behave differently from each other and U.S. stock markets may move in the opposite direction from one or more foreign stock markets.

Stocks of medium-sized companies tend to be more vulnerable to adverse developments, may be more volatile, and may be illiquid or restricted as to resale.

Because MSCI uses ESG factors to exclude, select and assign weights to certain companies included in the Underlying Index for non-financial reasons, the Fund may forego some market opportunities available to funds that do not use these factors. As a result, Fund may underperform other funds that do not use ESG factors. Further, information used by MSCI to evaluate the ESG factors may not be readily available, complete, or accurate, which could negatively impact MSCI's ability to apply its ESG standards when compiling the Underlying Index, which may negatively impact the Fund's performance. Companies deemed eligible by MSCI for inclusion in the Underlying Index may not reflect the beliefs and values of any particular investor and may not be deemed to exhibit positive or favorable ESG characteristics if different metrics were used to evaluate them.

The risks of investing in securities of foreign issuers can include fluctuations in foreign currencies, political and economic instability, and foreign taxation issues.

The performance of an investment concentrated in issuers of a certain region or country is expected to be closely tied to conditions within that region and to be more volatile than more geographically diversified investments.

Investments concentrated in a comparatively narrow segment of the economy may be more volatile than non-concentrated investments.

The Fund's use of a representative sampling approach will result in its holding a smaller number of securities than are in the underlying Index, and may be subject to greater volatility.

Derivatives may be more volatile and less liquid than traditional investments and are subject to market, interest rate, credit, leverage, counterparty and management risks. An investment in a derivative could lose more than the cash amount invested.

A decision as to whether, when and how to use futures involves the exercise of skill and judgment and even a well conceived futures transaction may be unsuccessful because of market behavior or unexpected events.

The Fund may become “non-diversified,” as defined under the Investment Company Act of 1940, as amended, solely as a result of a change in relative market capitalization or index weighting of one or more constituents of the Index.  Shareholder approval will not be sought when the Fund crosses from diversified to non-diversified status under such circumstances.

Active trading results in added expenses and may result in a lower return and increased tax liability.

The Portfolio is subject to certain other risks. Please see the current Program Description for more information regarding the risks associated with an investment in the Portfolio.
