Duperreault to retire from ACE

HAMILTON, Bermuda—ACE Ltd. Chairman Brian Duperreault will retire from the company on June 1, ACE announced Thursday.

Mr. Duperreault—who joined Hamilton, Bermuda-based ACE in 1994 as chairman, president and chief executive officer—will continue to serve as nonexecutive chairman of the board, ACE said.

During Mr. Duperreault's time as head of the insurer and reinsurer, ACE significantly expanded its lines of business and geographic reach, in large part through its 1999 acquisition of the property/casualty business of CIGNA Corp.

"Brian transformed ACE from a Bermuda-based specialty writer into a global multiline corporation. He leaves a legacy of extraordinary leadership and vision," ACE President and CEO Evan Greenberg said in a statement.
