Invesco PureBeta SM MSCI USA ETF (PBUS) Exchange: BATS

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, MSCI Inc. (the “Index Provider”) compiles, maintains and calculates the Underlying Index, which is designed to measure the performance of the large- and mid-capitalization segments of the U.S. equity market. The Index Provider weights securities in the Underlying Index by their free float-adjusted market capitalization. As of August 31, 2019, the Underlying Index was comprised of 637 securities with market capitalizations ranging from $2.26 million to $1 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”). For the avoidance of doubt, “PureBeta” refers to the market-capitalization weighted methodology of the Fund’s Underlying Index. It does not refer in any way to the purity or absence of errors or flaws of the market-capitalization weighted methodology of the Underlying Index or of the Fund in seeking to track the investment results of the Underlying Index. 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.
