INVESCO RUSSELL 1000R SIZE FACTOR ETF (OSIZ) Exchange: BATS

DELISTED - 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, Frank Russell Company (“Frank Russell” or the “Index Provider”) compiles, maintains, and calculates the Underlying Index, which includes a subset of the equity securities from the Russell 1000 Index (the “Parent Index”), an index comprised of the 1,000 largest-capitalization companies in the United States. To construct the Underlying Index, each constituent in the Parent Index is assigned a factor score based on the extent to which the constituent exhibits characteristics of smaller-capitalization companies relative to the other constituents in the Parent Index. A company’s size factor score is based on the company’s total market capitalization. An initial weight for each security is determined from the product of the security’s factor score and its weight in the Parent Index. These weights are adjusted to ensure that each constituent and the Underlying Index as a whole satisfy certain constraints with respect to factor exposure, diversification, liquidity, industry exposure, maximum security and minimum security weights, as compared to the Parent Index. Securities in the Parent Index are excluded from the Underlying Index if their relevant factor characteristics fall below an algorithmically-determined threshold, or if their adjusted weights fall below a certain de minimis amount. As of August 31, 2019, the Underlying Index was comprised of 658 securities with market capitalizations ranging from $451.99 million to $18.12 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.
