Effective June 1st 2026, Mereo Insurance Ltd has commenced underwriting the first Excess Casualty Energy policies under a renewal rights transaction undertaken between Everen Specialty Limited [ESL] and Cedar Trace, the insurance, reinsurance, and asset management group that is strategically aligned with Mereo.
A spokesperson said, “Under the transaction, ESL’s underwriting team and underwriting systems supporting the portfolio will also transition to Cedar Trace, providing continuity of coverage and systems as well as a team well known to the existing policyholders. The unit will be headed by Carla Greaves, the former ESL Chief Underwriting Officer.”
The transaction’s origination, structuring, and negotiation was led by Julia Mansfield, Head of Casualty. “We are delighted to welcome Carla and her team and to offer capacity to the existing ESL policyholders with AM Best ‘A- rated’ security. We look forward to working in partnership with ESL to ensure a smooth and seamless transition of this portfolio to the Mereo balance sheet,” noted Mansfield.
“I am really pleased to be able to bring myself and my team across to give continuity of coverage to the existing policyholders and their brokers,” said Carla Greaves. “We are also pleased to also announce a TPA arrangement with ESL to provide continuity of claims handling services.”
“The transaction supports our vision to become a leading global insurance and reinsurance business, and reflects our commitment to develop high-quality primary insurance business,” noted David Croom Johnson, a partner at Cedar Trace and Mereo’s Chief Executive Officer.
