He joined AIM in 2000 as a senior investment officer, contributing to the management teams of the AIM Select Equity Fund and AIM Diversified Dividend Fund before being named chief equity officer in 2004. The decision to replace Mr. Ferguson in the chief equity officer position is "under review," said David Bachert, manager of media relations.
