Perpetual has appointed its current group executive transformation officer Gillian Larkins as chief financial officer (CFO).
She replaces Roger Burrows, who announced his resignation on 5 November and who will continue in a transitional role until early February.
"Since joining the company, Gillian has been instrumental in helping the transformation office move from the design to the delivery stage and ensuring we are on track to deliver on its objectives," Perpetual chief executive managing director Geoff Lloyd said.
The transformation program was announced in June and Larkins' role as CFO will play an important part in meeting the goals of the program, including simplifying the company's corporate structure and refocusing its operational activities, Lloyd added.
Larkins joined Perpetual in October this year, previously holding the role of CFO and managing director of Westpac Institutional Bank.
Prior to that she worked as Citigroup's country CFO, Australia and New Zealand.
Larkins has selected Angus Benbow to assume responsibility for the transformation to "ensure we continue the good progress we've made", Lloyd said.
The $340 billion fund has welcomed three senior investment executives to its London office as it continues to internalise the management of international equities, its single largest asset allocation.
The fund has hired a former ART executive as its new head of group strategy.
The sovereign wealth fund has revealed six internal hires to support the execution of key strategies.
The fund has announced the departure of a second senior executive in as many months, with its chief member officer to finish up mid-December.
