Strategy. The Fund is an actively managed exchange-traded fund (ETF) that seeks to achieve its investment objective by investing, under normal market conditions, at least 80% of its assets in securities of companies that are principally engaged in the U.S. real estate industry and included within the FTSE NAREIT All Equity REITs Index. The Fund considers a company to be principally engaged in the U.S. real estate industry if it: (i) derives 50% of its revenues or profits from the ownership, leasing, management, construction, financing or sale of U.S. real estate; or (ii) has at least 50% of the value of its assets invested in U.S. real estate.

The Fund considers a company to be principally engaged in the U.S. real estate industry if it: (i) derives 50% of its revenues or profits from the ownership, leasing, management, construction, financing or sale of U.S. real estate; or (ii) has at least 50% of the value of its assets invested in U.S. real estate. The Fund plans to invest principally in equity real estate investment trusts (REITs). Equity REITs pool investors funds for investments primarily in real estate properties or real estate-related loans (such as mortgages). The Fund also may invest in real estate operating companies (REOCs), as well as securities of other companies principally engaged in the U.S. real estate industry. REOCs are similar to REITs, except that REOCs reinvest their earnings into the business, rather than distributing them to unitholders like REITs. The Fund structures and selects its investments primarily from a universe of securities that are included within the FTSE NAREIT All Equity REITs Index at the time of purchase. In constructing the portfolio, Invesco Advisers, Inc., the Funds sub-adviser (the Sub-Adviser), analyzes quantitative and statistical metrics to identify attractively priced securities. The Sub-Adviser will consider selling or reducing a security position if: (i) its relative valuation has fallen below desired levels; (ii) its risk/return profile has changed significantly; (iii) its fundamentals have changed; or (iv) a more attractive investment opportunity is identified. The Sub-Adviser generally conducts the security and portfolio evaluation process monthly. The Fund is non-diversified and therefore is not required to meet certain diversification requirements under the Investment Company Act of 1940, as amended (the 1940 Act). Concentration Policy . The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of companies that are principally engaged in the U.S. real estate industry.
