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 23% 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 equity securities represented in the MSCI World SRI Index (the Underlying Index) and in derivatives and other instruments that have economic characteristics similar to such securities.

The Underlying Index includes common stocks of large- and mid-capitalization companies from 23 developed market countries, including the U.S. The Underlying Index is a free float-adjusted market capitalization weighted index that is designed to represent the performance of companies that have high Environmental, Social and Governance (ESG) ratings relative to their sector peers, as determined by MSCI Inc. (MSCI), the index provider of the Underlying Index. The investment universe for the Underlying Index starts with constituents (i.e., a company or stock that is part of the index) included in the MSCI Global Investable Market Indexes. Companies are then excluded from the Underlying Index if: (1) they have any tie to controversial weapons, as defined by MSCI; (2) they are manufacturers or producers, as determined by MSCI, of civilian firearms, nuclear weapons (or of components or delivery platforms that can be used for nuclear weapons and/or provide auxiliary services related to nuclear weapons), or tobacco, or, with respect to civilian firearms and tobacco, derive 5% or more of their revenues from certain activities, such as distribution, production, retail, supply and licensing of such products; (3) their revenues from adult entertainment, alcohol, conventional weapons, gambling, genetically modified organisms, nuclear power, or thermal coal-based power generation exceed the business involvement thresholds determined by MSCI; (4) they derive any revenue (either reported or estimated) from unconventional fossil fuel extraction or thermal coal mining; or (5) they have evidence of ownership of fossil fuel reserves, as determined by MSCI.

MSCI utilizes proprietary ratings and research provided by MSCI ESG Research LLC (MSCI ESG Research) to assign the remaining companies an “ESG Rating” and an “ESG Controversies Score.” Companies must meet a

minimum ESG Rating and ESG Controversies Score to be eligible for inclusion in the Underlying Index.

According to MSCI ESG Research, an ESG Rating is based on a company’s ability to manage ESG risks and opportunities relative to its industry peers. MSCI ESG Research uses a quantitative model to evaluate the ability of companies to manage key issues, such as carbon emissions, water stress, or health and safety (each, a “Key Issue”) within their respective industries. Points of data include the company’s risk exposure to a particular Key Issue (by evaluating certain business metrics such as core product and business segments) and the company’s demonstrated management capabilities (by evaluating its management strategies and track record of performance in managing risks or opportunities). Other factors, such as a company’s ability to capitalize on certain opportunities presented by a particular risk and the company’s alleged involvement in ESG controversies, are also evaluated. Companies are assigned scores based on these various factors, which are then combined and normalized relative to their industry peers to create the final ESG Ratings. The Underlying Index methodology targets securities of companies making up the top 25% of the free float-adjusted market capitalization in each representative sector of each region represented in the Underlying Index according to their ESG Ratings.

An ESG Controversies Score is based on a company’s involvement in very serious controversies involving the negative ESG impact of its operations and/or products and services that are linked to specific international norms and principles represented by the UN Declaration of Human Rights, global conventions, such as the International Labour Organization (ILO) Fundamental Conventions, and the UN Global Compact.

The Underlying Index is rebalanced quarterly and reconstituted annually. The Fund is generally rebalanced and reconstituted in accordance with the Underlying Index.

In seeking to track the performance (before fees and expenses) of the Underlying Index, the Adviser utilizes a “sampling” methodology pursuant to which the Adviser will invest substantially all of the Fund’s assets in securities comprising the Underlying Index in approximately the same proportion as such securities’ weighting in the Underlying Index, but will generally not purchase all of the securities comprising the Underlying Index.

The Fund can use exchange-traded futures contracts, including index futures, to gain exposure to equity securities represented in the Underlying Index while managing cash balances. These investments are not subject to the ESG considerations discussed above.

The Fund intends to be diversified in approximately the same proportion as the Underlying Index is diversified. The Fund may become “non-diversified,” as defined in the Investment Company Act of 1940, solely as a result of a change in relative market capitalization or index weighting of one or more constituents of the Underlying Index. A “non-diversified” fund can invest a greater percentage of its assets in a small group of issuers or in any one issuer than a diversified fund can. Shareholder approval will not be sought if the Fund becomes non-diversified due solely to a change in the relative market capitalization or index weighting of one or more constituents of the Underlying Index.

In seeking to track the Underlying Index, the Fund may from time to time have significant exposure to a particular sector.

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:

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. The value of

2 Invesco MSCI World SRI Index Fund

invesco.com/usGLRE-SUMPRO-1

the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, natural or environmental disasters, widespread disease or other public health issues, war, military conflict, acts of terrorism, economic crisis or adverse investor sentiment generally. 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.

Investing in Stocks Risk. The value of the Fund’s portfolio 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.

The prices of individual stocks generally do not all move in the same direction at the same time. However, individual stock prices tend to go up and down more dramatically than those of certain other types of investments, such as bonds. A variety of factors can negatively affect the price of a particular company’s stock. These factors may include, but are not limited to: poor earnings reports, a loss of customers, litigation against the company, general unfavorable performance of the company’s sector or industry, or changes in government regulations affecting the company or its industry. To the extent that securities of a particular type are emphasized (for example foreign stocks, stocks of small- or mid-cap companies, growth or value stocks, or stocks of companies in a particular industry), fund share values may fluctuate more in response to events affecting the market for those types of securities.

Mid-Capitalization Companies Risk. Mid-capitalization companies tend to be more vulnerable to changing market conditions, may have little or no operating history or track record of success, and may have more limited product lines and markets, less experienced management and fewer financial resources than larger companies. These companies’ securities may be more volatile and less liquid than those of more established companies, and their returns may vary, sometimes significantly, from the overall securities market.

ESG Risk. Because MSCI uses ESG factors to exclude, select and assign weights to certain stocks of 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. Consequently, the Fund may underperform other funds that do not use ESG factors. Further, there is a risk that 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. MSCI’s assessment of a company, based on the company’s level of involvement in a particular industry or the company’s ESG Rating and ESG Controversies Score, may differ from that of other funds, the Adviser or an investor. As a result, the 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. Not every investment or issuer held by the Fund may be evaluated for ESG considerations.

Foreign Securities Risk. The Fund's foreign investments may be adversely affected by political and social instability, changes in economic or taxation policies, difficulty in enforcing obligations, decreased liquidity or increased volatility. Foreign investments also involve the risk of the possible seizure, nationalization or expropriation of the issuer or foreign deposits (in which the Fund could lose its entire investments in a certain market) and the possible adoption of foreign governmental restrictions such as exchange controls. Foreign companies generally may be subject to less stringent

regulations than U.S. companies, including financial reporting requirements and auditing and accounting controls, and may therefore be more susceptible to fraud or corruption. There may be less public information available about foreign companies than U.S. companies, making it difficult to evaluate those foreign companies. Unless the Fund has hedged its foreign currency exposure, foreign securities risk also involves the risk of negative foreign currency rate fluctuations, which may cause the value of securities denominated in such foreign currency (or other instruments through which the Fund has exposure to foreign currencies) to decline in value. Currency exchange rates may fluctuate significantly over short periods of time. Currency hedging strategies, if used, are not always successful.

Geographic Focus Risk. The Fund may from time to time have a substantial amount of its assets invested in securities of issuers located in a single country or a limited number of countries. Adverse economic, political or social conditions in those countries may therefore have a significant negative impact on the Fund’s investment performance.

Sector Focus Risk. The Fund may from time to time have a significant amount of its assets invested in one market sector or group of related industries. In this event, the Fund’s performance will depend to a greater extent on the overall condition of the sector or group of industries and there is increased risk that the Fund will lose significant value if conditions adversely affect that sector or group of industries.

Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, the Fund would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming. Additionally, the Fund generally rebalances its portfolio in accordance with the Underlying Index, and, therefore, any changes to the Underlying Index’s rebalance schedule will typically result in corresponding changes to the Fund’s rebalance schedule.

Non-Correlation Risk. The Fund’s return may not match the return of the 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 and reconstituting the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. The Fund’s use of a representative sampling approach may cause the Fund not to be as well-correlated with the return of the Underlying Index as would be the case if the Fund purchased all of the securities in the Underlying Index in the proportions represented in the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Sampling Risk. The Fund’s use of a representative sampling approach may result in it holding a smaller number of securities than are in the Underlying Index. As a result, an adverse development respecting an issuer of securities held by the Fund could result in a greater decline in NAV than would be the case if the Fund held all of the securities in the Underlying Index. To the extent the assets in the Fund are smaller, these risks will be greater.

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 holding a position in 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

3 Invesco MSCI World SRI Index Fund

invesco.com/usGLRE-SUMPRO-1

substantially greater than the amount invested in the derivative or the anticipated value of the underlying asset, 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. Derivatives strategies may not always be successful. For example, 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.

Non-Diversification Risk. To the extent the Fund becomes non-diversified the Fund may invest a greater portion of its assets in the obligations or securities of a small number of issuers or any single issuer than a diversified fund can. In such circumstances, a change in the value of one or a few issuers’ securities will therefore affect the value of the Fund more than if it was a diversified fund.

Performance Information

The bar chart and performance table provide an indication of the risks of investing in the Fund. The bar chart shows changes in the performance of the Fund from year to year as of December 31. For periods prior to June 29, 2020, performance shown is that of the Fund using its previous investment strategy. Therefore, the past performance shown for periods prior to June 29, 2020 may have differed had the Fund’s current investment strategy been in effect. The performance table compares the Fund’s performance to that of a broad measure of market performance and additional benchmarks with characteristics relevant to the Fund. The Fund’s past performance (before and after taxes) is not necessarily an indication of its future performance.

Fund performance reflects any applicable fee waivers and expense reimbursements. Performance returns would be lower without applicable fee waivers and expense reimbursements.

All Fund performance shown assumes the reinvestment of dividends and capital gains and the effect of the Fund’s expenses.

Updated performance information is available on the Fund’s website at www.invesco.com/us.

Effective February 28, 2024, the Fund changed its broad-based securities market benchmark from the MSCI World SRI Index (Net) to the MSCI World IndexSM (Net) to reflect that the MSCI World IndexSM (Net) can be considered more broadly representative of the overall applicable securities market.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown, and after-tax returns shown are not relevant to investors who hold their Fund shares through tax-advantaged arrangements, such as 401(k) plans, 529 college savings plans or individual retirement accounts. After-tax returns are shown for Class A shares only and after-tax returns for other classes will vary.
