Conduit Re has appointed Greg Roberts as group chief underwriting officer. Roberts takes over this role from Trevor Carvey, the group chief executive officer and the current group chief underwriting officer, with effect from March 1, 2022, when he will also join the executive committee.

The appointment is subject to Bermuda immigration approval.

Roberts joined Conduit prior to the IPO in 2020 to lead Conduit’s property underwriting. Before that, he was head of AmTrust Re.

“It was always our intention to split the roles of CEO and CUO to allow Trevor to concentrate on his role as CEO and the strategic development of the group,” commented Neil Eckert, group executive chairman of Bermuda-based Conduit.

“Under Trevor’s leadership, we are now through the initial foundational phase of building out both our underwriting team and portfolio. During that process, Greg has emerged as the outstanding candidate to assume the mantle of CUO, and we feel that now is the right time to promote Greg into this key role,” Eckert added.

Conduit Re is a pure play global reinsurance business based in Bermuda. Conduit Reinsurance Limited is licensed by the Bermuda Monetary Authority as a Class 4 insurer.
