Specialty insurance and reinsurance underwriter Argo Group International Holdings has announced the appointment of Tom McCartney as group head of ceded reinsurance.

McCartney will be based in Chicago. He succeeds Katie Partington Howarth, who is leaving the company to take a position at AXIS Re.

“Tom has been closely involved in shaping Argo’s reinsurance strategy,” said Tim Carter, executive vice president and chief underwriting officer at Argo. “His strong technical skills and relationships in the market make him ideally suited for this important role. We look forward to working with Tom as we look to build on our past success. We would also like to thank Katie for her contributions and wish her the best in the future.”

McCartney joined Argo in February 2020 as vice president of ceded reinsurance for the Americas. Prior to joining Argo, McCartney served as vice president of ceded reinsurance for Allied World in Bermuda.
