However, estimating total OCIO assets under management is difficult due to the lack of standards, Chestnut Advisory writes.
One of those standards defines an OCIO mandate. Some OCIO providers report different mandates and client types; some exclusively report institutional mandates; and others include private wealth mandates in their AUM. Some providers include legacy assets the firm did not allocate, while others do not, according to the report.
“Our definition of an OCIO mandate is similar to the new definition proposed by the CFA Institute 1—an engagement [in which] the OCIO provides both strategic investment advice and investment management services in one engagement for a pool of assets,” the report stated. “This definition includes mandates for asset class sleeves, partial portfolios and full portfolios.”
Chestnut defines an OCIO mandate as an engagement in which a third party provides both strategic investment advice and investment management services for a pool of assets.
“There are many different types of mandates and clients included in the ‘OCIO AUM’ reported by providers today,” said Amanda Tepper, Chestnut Advisory’s co-managing partner, in a statement. “Our new definition of an OCIO mandate is a first step toward establishing an industry standard for OCIO AUM.”
Chestnut researched the 2024 AUM of 134 different OCIO firms, acknowledging “the AUM values on our list are imperfect” due to the varying standards. The report also stated it expects to include more European and Asian OCIO providers in future rankings.
