The sale comes on the heels of Aon and Willis Towers calling off its proposed merger and ending litigation with the U.S. Department of Justice in July. The merger, which was first announced in March 2020 and received shareholder approval in August 2020, was challenged in June, with the DOJ asserting the deal could eliminate competition, raise prices and hamper innovation for U.S. businesses, employers and unions that use the two consultancies’ services.

“Following the termination of the proposed combination with Aon, we’ve been taking time to reflect on what we have learned about WTW over the last 16 months and determine how we’ll move forward as an independent company,” said John Haley, chief executive officer of Willis Towers Watson, in a press release on Friday. “While we highly value Willis Re and our colleagues who contribute to its success, we concluded that divestment was the appropriate path for this business and for WTW.”
