Claude Lefebvre, a founding member of Hamilton Re, is leaving his job. Lefebvre, chief underwriting officer, partnerships & casualty reinsurance, is departing the Bermuda platform for Hamilton Insurance Group to pursue other interests, Hamilton Re said, though it did not disclose additional details.

Plans call for Lefebvre to stay on until the end of March and then remain available as needed while completing his period of garden leave, according to the departure announcement.

“Claude’s role in founding and building Hamilton Re has been meaningful,” CEO Kathleen Reardon said in prepared remarks. “He was instrumental in assisting us in building a market reputation for superior client service.”

Lefebvre took on his current position only in September, as part of a series of leadership changes Reardon said at the time she made to “focus on strategic and executive imperatives as we define what it means to be a Tier 1 company in today’s market.”

Reardon become CEO of Hamilton in early 2014, at which time Lefebvre was given the expanded title of chief underwriting officer, casualty and specialty. He has more than 23 years of reinsurance industry experience, including stints at Arch Reinsurance in Bermuda and CNA Re.

Brian Duperreault, former head of Hamilton Insurance and the current CEO of American International Group, led a group of investors that helped create Hamilton Re in 2014 by buying S.A.C. Re Ltd. from Steven Cohen, the billionaire founder of SAC Capital Advisors LP, for $1.8 billion.
