Willis also announced Chairman Victor Ganzi would not stand for re-election at the annual shareholder meeting in 2022 after his current term expires. The announcement comes months after a pushback from U.S. regulators forced Willis and Aon to call off their $30 billion merger that would have created the world's largest insurance broker, topping current leader Marsh & McLennan Companies Inc. In the weeks following the derailed merger plans, Willis named company insider Carl Hess as its next CEO and president.
