normal market conditions, at least 80% of
the Fund’s net assets, plus any borrowings for investment purposes, will be invested in those securities, and in derivatives and other instruments that have economic characteristics similar to such securities. The Fund
will concentrate its investments without limit in the metals, mining and minerals industries.
The Fund may invest
up to 20% of its total assets in gold or silver bullion, in other precious metals, in metals naturally occurring with precious metals, in certificates representing an ownership interest in those metals, and in gold or silver coins. The
Fund’s investment in shares of ETFs and other exchange-traded products that invest in gold bullion (Gold ETFs) are subject to this investment restriction.
The Fund may invest in U.S. or foreign companies, including companies in
developing or emerging markets, i.e., those that are generally in the early stages of their industrial cycles, and depositary receipts. The Fund has no limit on its foreign investments. The Fund may buy securities issued by companies of any size or market
capitalization range and at times might increase its emphasis on securities of issuers in a particular capitalization range.
As part of
its process for identifying investment opportunities, the portfolio managers primarily rely on evaluations of a company's fundamentals, scoring companies in the gold, metals and minerals, and mining universe using a systematic and
proprietary process. Using financial statements and other relevant sources of data, the portfolio managers evaluate the relative attractiveness of stocks based on multiple metrics, including valuation, business and
stock price trends, and quality of management. To arrive at buy and sell decisions, portfolio managers consider the growth trends and the valuation of the stocks of particular companies.
The Fund can also invest up to 25% of its total assets in the Subsidiary. The Subsidiary will invest in gold bullion and other precious metals, Gold ETFs, commodity-linked derivatives
related to gold or other special minerals (including commodity futures, financial futures, options and swap contracts), and certain fixed-income securities and other investments that may serve as margin or collateral for its
derivatives positions. Investments in the Subsidiary are intended to provide the Fund with exposure to minerals commodities market returns within the limitations of the federal tax requirements that apply to the Fund. In
managing the Subsidiary's portfolio, Invesco Advisers, Inc. (the “Adviser”) will be subject to the same operational guidelines that apply to the management of the Fund. The Fund applies its investment restrictions and
compliance policies and procedures, on a look-through basis, to the Subsidiary.
The Fund’s investment in the Subsidiary may vary based on the portfolio
managers’ use of gold bullion and other precious metals, Gold ETFs, different types of
commodity-linked derivatives, fixed-income securities and other investments. Since the Fund may invest a substantial portion of its assets in the Subsidiary, which may hold certain of the investments described in this prospectus, the Fund may
be considered to be investing indirectly in those investments through its Subsidiary and subject to the risks associated with any investments of the Subsidiary. Therefore, references in this prospectus to
investments by the Fund include the Fund’s indirect investments through the Subsidiary.
In addition to investing in derivative instruments through the Subsidiary,
the Fund may also invest directly in derivative instruments, including options. The Fund may use
options for liquidity, hedging and investment purposes. Up to 25% of the Fund’s total assets can be subject to call options the Fund sells. However, the Fund will not write or purchase any call option that will cause the value
of the Fund’s calls on a particular security to exceed 3% of the Fund’s total assets. The Fund may also use equity-linked notes (ELNs) to obtain exposure to gold or other precious metals/minerals mining companies and options
thereon. ELNs are hybrid derivative-type instruments that are specially designed to combine the characteristics of investing in one or more reference securities (such as a single stock, ETF, or an index or basket of
securities (underlying securities)) and a related derivative, such as a put or call option (or a combination thereof), in a single
note form (typically senior, unsecured
debt) issued by financial institutions. The options within the ELNs in which the Fund invests will generally have covered call and/or cash secured put strategies embedded within them. When the Fund purchases an ELN from the
issuing counterparty, the Fund is generally entitled to receive a premium generated by options positions within the ELN. Therefore, the ELNs are intended to provide recurring cash flow to and reduce the overall
volatility of the Fund based on the premiums received from selling the options. When the Fund sells call options within an ELN, it receives a premium but limits its opportunity to profit from an increase in the market value of the
underlying securities to the exercise price of the call option (plus the premium received).
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 the Fund’s investments may
go up or down due to general market conditions that are not specifically related to the particular issuer. These market conditions may include real or perceived adverse economic conditions, changes in trade regulation or
economic sanctions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability and uncertainty, natural or environmental disasters,
widespread disease or other public health issues, war, military conflict, acts of terrorism, economic crisis or adverse investor sentiment generally, among others. Certain changes in the U.S. economy in particular, such as when the U.S.
economy weakens or when its financial markets decline, may have a material adverse effect on global financial markets as a whole, and on the securities to which the Fund has exposure. Increasingly strained relations
between the U.S. and foreign countries, including as a result of economic sanctions and tariffs, may also adversely affect U.S. issuers, as well as non-U.S. issuers.
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.
Investments in Mining, Minerals and Metal
Industry Securities Risk. Investments in mining, minerals and metal industry companies may be speculative and may be subject to greater
price volatility than
