Atrium Underwriters Limited has decided to exit marine reinsurance in the New Year.

“Continuing in the class was deemed unviable as Atrium looks to focus their efforts and capacity into their direct specialty classes,” said the managing agent for Lloyd’s Syndicate 609, which did not provide further details.

“The underwriter of the marine reinsurance account, Andrew Hedges, will stay with the business for the foreseeable future to ensure the satisfactory run-off of the portfolio.”

For 2023, Syndicate 609’s capacity stands at £875 million – an increase from 2022’s £652 million.
