Invesco S&P MidCap 400 Revenue ETF (RWK) Exchange: NYSE ARCA

The Fund generally will invest at least 90% of its total assets in the securities that comprise the Underlying Index Strictly in accordance with its guidelines and mandated procedures, S&P Dow Jones Indices LLC (“S&P DJI” or the “Index Provider”) compiles, maintains, and calculates the Underlying Index, which includes positive revenue producing constituent securities of the S&P MidCap 400® Index (the “Parent Index”), an index comprised of common stocks of 400 mid-cap companies that generally represents the mid-cap universe of the U.S. equity market. Unlike the Parent Index, which employs a market-capitalization weighted methodology, the Underlying Index weights each constituent security based on the sum of the company’s revenues for the trailing four quarters, subject to a maximum 5% per company weighting. As of August 31, 2019, the Underlying Index was comprised of 395 securities with market capitalizations ranging from $217.07 million to $14.71 billion. The Fund employs a “full replication” methodology in seeking to track the Underlying Index, meaning that the Fund generally invests in all of the securities comprising the Underlying Index in proportion to their weightings in the Underlying Index. 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 more than 25% of the value of its net assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.
