This year Institutional Investor changed the methodology behind the II300 to better reflect how asset allocators analyze, hire, and fire money managers. Investment management shops that are owned by or rolled up into a larger organization, such as an insurer, holding company, or bank, are broken out and reported separately. In past years II included the money managed by affiliated firms in the parent company’s total assets. The II300 was created using data from research firm eVestment and supplemented by information provided by asset managers directly to II.
