Supplement Risk Narrative [Text Block]	aimgs202032_SupplementRiskNarrativeTextBlock	The following information is added underneath the last risk appearing under the heading “Fund Summary – Principal Risks of Investing in the Fund”: “Concentration Risk. To the extent, an underlying fund invests a greater amount in any one sector or industry, an underlying fund’s performance will depend to a greater extent on the overall condition of the sector or industry, and there is increased risk to an underlying fund if conditions adversely affect that sector or industry. Debt Securities Risk. The underlying funds may invest in debt securities that are affected by changing interest rates and changes in their effective maturities and credit quality. Developing/Emerging Markets Securities Risk. Securities issued by foreign companies and governments located in developing countries may be affected more negatively by inflation, devaluation of their currencies, higher transaction costs, delays in settlement, adverse political developments, the introduction of capital controls, withholding taxes, nationalization of private assets, expropriation, social unrest, war or lack of timely information than those in developed countries. Exchange-Traded Funds Risk. An investment by the Fund or underlying fund in ETFs generally presents the same primary risks as an investment in a mutual fund. In addition, an ETF may be subject to the following: (1) a discount of the ETF’s shares to its net asset value; (2) failure to develop an active trading market for the ETF’s shares; (3) the listing exchange halting trading of the ETF’s shares; (4) failure of the ETF’s shares to track the referenced index; and (5) holding troubled securities in the referenced index. ETFs may involve duplication of management fees and certain other expenses, as the Fund or underlying fund indirectly bears its proportionate share of any expenses paid by the ETFs in which it invests. Further, certain of the ETFs in which the Fund or underlying fund may invest are leveraged. The more the Fund or underlying fund invests in such leveraged ETFs, the more this leverage will magnify any losses on those investments. Financial Institutions Risk. Investments in financial institutions may be subject to certain risks, including, but not limited to, the risk of regulatory actions, changes in interest rates and concentration of loan portfolios in an industry or sector. Financial institutions are highly regulated and may suffer setbacks should regulatory rules and interpretations under which they operate change. Likewise, there is a high level of competition among financial institutions which could adversely affect the viability of an institution. Forward Foreign Currency Exchange Contracts. The use of forward contracts involves the risk of mismatching an underlying fund’s objectives under a forward contract with the value of securities denominated in a particular currency. Furthermore, such transactions reduce or preclude the opportunity for gain if the value of the currency should move in the direction opposite to the position taken. There is an additional risk to the effect that currency contracts create exposure to currencies in which an underlying fund’s securities are not denominated. Unanticipated changes in currency prices may result in poorer overall performance for an underlying fund than if it had not entered into such contracts. Non-Correlation Risk. An underlying fund’s return may not match the return of the underlying index of certain underlying ETFs for a number of reasons. For example, an underlying fund incurs operating expenses not applicable to the underlying index of certain ETFs, and incurs costs in buying and selling securities, especially when rebalancing an underlying fund’s securities holdings to reflect changes in the composition of the underlying index of certain underlying ETFs. In addition, the performance of an underlying Fund and the underlying index of certain underlying ETFs may vary due to asset valuation differences and differences between an underlying fund’s portfolio and the underlying index of certain underlying ETFs resulting from legal restrictions, cost or liquidity constraints. Options Risk. A decision as to whether, when and how to use options involves the exercise of skill and judgment and even a well conceived option transaction may be unsuccessful because of market behavior or unexpected events. The prices of options can be highly volatile and the use of options can lower total returns. Preferred Securities Risk. There are special risks associated with investing in preferred securities. Preferred securities may include provisions that permit the issuer, in its discretion, to defer or omit distributions for a certain period of time. If an underlying fund owns a security that is deferring or omitting its distributions, an underlying fund may be required to report the distribution on its tax returns, even though it may not have received this income. Further, preferred securities may lose substantial value due to the omission or deferment of dividend payments. 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. Tax Risk. If the U.S. Treasury Department were to exercise its authority to issue regulations that exclude from the definition of “qualifying income” foreign currency gains not directly related to the underlying fund’s business of investing in securities, the underlying fund may be unable to qualify as a regulated investment company for one or more years. In this event, the underlying fund’s Board may authorize a significant change in investment strategy or underlying fund liquidation.” The following information is hereby deleted in its entirety under the heading “Fund Summary – Principal Risks of Investing in the Fund”. “Limited Number of Holdings Risk Reverse Repurchase Agreements Risk”
