Clarendon National Insurance Company

Investment and operational decisions flow through Enstar Group's centralized management team, led by CEO Dominic Silvester. Enstar is the ultimate controlling entity and runs a unified strategy across its run-off platforms. Clarendon operates as a key legal entity within that structure, but does not publish a separate management roster.

No. Clarendon National's primary business is managing discontinued or legacy insurance portfolios. It does not actively underwrite new business; instead, it acquires blocks of reserves from insurers and reinsurers looking to exit lines or reduce capital drag from old liabilities.

These are the two primary reinsurance deal structures Clarendon uses. A Loss Portfolio Transfer (LPT) is an agreement where Clarendon assumes existing loss reserves in exchange for the remaining premium and associated investment float. An Adverse Development Cover (ADC) is a reinsurance contract that protects a seller against future claims on known reserves exceeding an agreed-upon threshold, transferring that tail risk to Clarendon.

Public records and Altss research identify SiriusPoint Ltd. and American International Group (AIG) as major counterparties. SiriusPoint has been a party to Loss Portfolio Transfer deals, and AIG entered into a prominent $850 million Adverse Development Cover with Enstar entities, including Clarendon, in September 2023.

Clarendon was formerly a subsidiary of Hannover Re, the German reinsurer, before being acquired by Enstar Group in 2011. The acquisition allowed Enstar to obtain a US-domiciled platform with a legacy licensing footprint for its run-off consolidation strategy.

Capital is provided through its parent company, Enstar Group Limited, a publicly traded company listed on the Nasdaq that specializes in acquiring and managing run-off insurance portfolios globally. Enstar's own capital structure includes permanent equity, debt facilities, and the internally generated cash flows from its acquired reserve portfolios.

Clarendon invests in the secondary risk market for insurance liabilities, effectively operating at the intersection of buyouts and special situations. It targets discontinued, non-core legacy books from global property and casualty insurers and reinsurers, managing the associated claims run-off over multi-year horizons.
