Under the terms of the agreement Citi will perform global shareholder and transfer agency services for AHL and Man multi-manager private investor products, which are distributed globally through Man’s network of approved intermediaries and distribution partners.

Citi said it will commence their role at the end of March and a joint project will then follow to enhance services to Man’s funds, simplify administration arrangements and migrate all of Man’s private investor products onto Citi’s platform.

Man head of product and client operations at Simon White said Citi has been chosen based on its proven expertise, unrivalled global presence and demonstrable track record of service delivery for private investor operations.

"Both Citi and Man are committed to maintaining and improving the excellent client service levels that we have worked so hard to achieve," White said.

Following Citi’s appointment, intermediaries will continue to be supported by their usual regional offices and contacts at Man.
