Three parties are believed to be carrying out due diligence on AMP Capital Investors Limited, owned by AMP Limited (ASX:AMP). Sources said the parties have quietly been given access to a data room by AMP ahead of plans for a demerger of the unit. It is understood at least one is US-based and that one out of Asia has been building a stake in AMP.

A large number of global funds and private equity firms are said to have made approaches to AMP about AMP Capital, to be renamed Collimate Capital Funds Management. Ares Management Corporation (NYSE:ARES) is not thought to be among the groups weighing an AMP Capital purchase.
