Kevin Uebelein, CEO of the Alberta Investment Management Corp., will leave the manager for pension, endowment and government funds in Alberta by June 30.
His departure date, part of an agreement with AIMCo's board, represents a "modest acceleration by a matter of months of the plan Kevin and the board already had in place," a spokesman said in an email.
The board has created a CEO recruitment committee to lead the effort to find a replacement by June 30, the spokesman said.
"AIMCo remains in very capable hands with Kevin continuing at the helm until that date, and he has the full support of the board and management as he continues to advance the many priorities before us," he added.
Mr. Uebelein has been CEO since January 2015, when he replaced Leo de Bever, who had been CEO at Edmonton-based AIMCo since it was created in 2008.
As of Dec. 31, AIMCo managed about C$119 billion ($91.1 billion) in assets.
