Perpetual are to restructure its operation following the departure to Fidelity Investments of group executive wealth management Gerard Doherty.
The restructure follows board approval of a strategic plan carried out earlier this year.
Perpetual's new business units comprise Australian equities, global equities, income and multi sector, private wealth and operations.
Each unit will be headed by a group executive reporting into Perpetual's managing director and chief executive David Deverall.
They will also be a part of the group's executive committee.
"An important aspect of the new structure is the prominence it gives to the business units within Perpetual Investments and their ability to deliver on our strategy," Deverall said.
Existing business units comprising of finance, corporate trust, risk and people and culture remain the same.
Doherty will take over the reigns at the American fund manger in January 2008 after approaching 15 years at Perpetual.
He replaces outgoing Fidelity managing director Michael Ohlsson, who resigned in August.
