Russell Investments conducts quarterly updates to its indexes to account for qualifying initial public offerings that occur following its annual mid-year index reconstitution, determining membership for its equity indexes primarily by objective, rules-based market-capitalization rankings and style attributes.  Membership in the Russell 2000, which remains in place for one year, is based on membership in the broad-market Russell 3000 Index.  The Russell 3000 also serves as the U.S. component to the Russell Global Index. Membership in the Russell Indexes means automatic inclusion in the appropriate growth and value style indexes.
