Markel has agreed to transfer a substantial portion of the risk from a $4.8 billion portfolio of run-off reinsurance business and certain insurance lines it has exited to Enstar subsidiary Cavello Bay Reinsurance. The deal sets a $2.6 billion retention for Markel’s insurance subsidiaries, with coverage above that level and additional protection if losses develop beyond current reserve estimates.
The arrangement is intended to cover losses paid from April 1, 2026, but it remains subject to regulatory approval and other closing conditions. Markel expects it to close by the end of 2026.
Key details
-
Business covered: The agreement applies to run-off business in Markel’s Global Reinsurance operation and certain exited insurance lines. The portfolio has net reserves of $4.8 billion.
-
Coverage: Cavello Bay will reimburse 100% of covered losses above a $2.6 billion aggregate retention. The agreement provides $2.3 billion of coverage against the existing reserves, plus up to $1.2 billion for adverse development beyond those reserves.
-
Premium and assets: Markel’s ceding subsidiaries will pay a $2.4 billion reinsurance premium. The premium, less applicable federal excise tax, will be paid with assets transferred at closing. The value of those assets will reflect any earnings, gains or losses between signing and closing.
-
Trust and collateral: Of the transferred assets, $500 million will go directly to Cavello Bay. The rest will be placed in a trust for the benefit of Markel’s ceding subsidiaries to secure Cavello Bay’s obligations. Cavello Bay must maintain collateral in the trust, and required collateral may increase in certain circumstances.
-
Claims and recapture rights: Markel’s ceding subsidiaries will retain control of claims, subject to agreed claims procedures. They also have the right to commute, or end, the agreement if specified recapture events occur.
-
Closing conditions and risks: The deal requires regulatory approval and other customary conditions. Markel identifies possible delays or failure to close, changes in reserve estimates, losses exceeding the agreement’s limit, and Cavello Bay’s ability to meet its payment and collateral obligations as factors that could affect the transaction.
Plain-English implications
The arrangement shifts much of the covered loss risk above Markel’s $2.6 billion retention to Cavello Bay, while leaving Markel with claims control. It does not cover losses within the retention, and the additional protection is capped; adverse development beyond the agreement’s limits would remain outside this coverage.
