Specialty insurer and reinsurer SiriusPoint Ltd. has promoted Ari Chester to Head of US and Canada Reinsurance, succeeding Warren Trace following his retirement after 38 years of service at Sirius Group and predecessor firms.
Chester transitions into his new role from Chief Operating Officer (COO), Americas Reinsurance at SiriusPoint, having joined in early 2021.
He will now take on responsibility for managing the firm’s US and Canadian business across property treaty, casualty treaty, and other specialty lines.
Prior to SiriusPoint, Chester served as a Partner at McKinsey & Company, where held leadership roles across underwriting, risk, and strategy serving re/insurers in the US, Bermuda, London Market, and Europe.
David Govrin, Global Chief Underwriting Officer (CUO) and President, Americas Reinsurance, commented: “I am delighted to welcome Ari to this role.
“With his broad industry experience and outstanding contribution since joining SiriusPoint, Ari will be instrumental in advancing our efforts to continue building our business, modernizing our platform, and supporting strategic growth for SiriusPoint.”
Chester added: “It is exciting to step into this role. Having gotten to know our underwriting teams over the last several months, SiriusPoint has world class talent and punches well above its weight.”
His predecessor, industry veteran Trace, served as President of North America Reinsurance and Deputy CUO for the Americas at Sirius Group, prior to the firm’s merger with Third Point Re last year. Before this, he served as the Chief Executive Officer (CEO) of Sirius Bermuda.
Commenting on his retirement, Monica Cramer Manhem, President International Reinsurance, said: “Warren has been a true industry leader. I value him as both a colleague and a friend, and we will miss his presence. I am grateful for Warren’s passion, his dedication to our company and the numerous people he has mentored and generously shared his time and expertise with.
“We all wish him well in his retirement. Ari has played an instrumental role in the launch of SiriusPoint, and I look forward to our continued collaboration and future successes.”
