Enstar Group Limited has entered into a significant adverse development cover reinsurance agreement with Markel Insurance. This deal covers a global portfolio of discontinued reinsurance lines and reserves for underwriting years 2025 and prior.
Why it matters
By transferring these legacy liabilities, Markel intends to reduce financial uncertainty and focus resources on its primary specialty insurance business. The arrangement allows for strategic realignment while Enstar takes on defined risk management responsibilities.
Enstar receives $2.4 billion in consideration to cover $2.3 billion of reserves, while Markel retains $2.6 billion in primary reserves. Enstar also provides $1.2 billion in additional adverse development cover above the total $4.8 billion subject reserves.
