A captive insurance company is an insurance or reinsurance company established and owned by a non-insurance parent group, primarily to insure or reinsure the risks of that parent group or of related parties. The captive structure allows the corporate group to retain underwriting profit, tailor cover to its specific risks, gain direct access to the reinsurance market, and (in some jurisdictions) achieve significant tax efficiency.
Category: Captives and alternative risk transfer Also known as: Captive, Captive insurer, Captive insurance Established / Codified: Concept in modern form from 1950s (Fred Reiss); first captive jurisdiction Bermuda 1962 Related concepts: Single parent captive, Group captive, Protected cell company, Bermuda insurance market
A captive insurance company functions as an insurer in the legal sense — issuing policies, collecting premiums, paying claims — but with a tightly defined customer base limited to its parent and related entities (single-parent captive), to defined group members (group captive), or to cell participants in a PCC (cell captive). The captive is normally domiciled in a specialist captive jurisdiction (Bermuda, Guernsey, Cayman, Isle of Man, Vermont, Singapore, Luxembourg, Malta) with proportionate regulation calibrated to the limited customer base.
The first identifiable modern captive was established in 1962 by F. M. Reiss in Bermuda, though similar arrangements existed under the name “self-insurer” earlier. The modern captive industry developed from the 1970s with the deepening of the Bermuda and Cayman markets.
Captives are insurance undertakings subject to local regulation in their domicile jurisdiction. Principal regulatory frameworks include: Bermuda Insurance Act 1978 (class-based); Cayman Insurance Act 2010 (Class B); Guernsey Insurance Business Law 2002; Isle of Man Insurance Act 2008; Vermont Captive Insurance Act 1981 (8 V.S.A. Ch 141). Solvency II Recital 21 confirms the principle of proportionality for captive supervision in the EU. UK captives, when domiciled in the UK, are PRA-regulated under Solvency UK (with limited proportionality concessions).
US federal tax treatment of captives is governed by Internal Revenue Code §§831 and 953, with significant case-law on what constitutes “insurance” for tax purposes (notably Helvering v Le Gierse 312 US 531 (1941) requiring risk-shifting and risk-distribution).
A typical captive operates as follows: the parent group establishes the captive in a chosen domicile; the captive writes direct insurance covering specified parent group risks (often employer’s liability, public liability, property, motor, professional indemnity); premiums are calculated to reflect actuarial expected loss plus expenses, capital charges, and a margin; claims are settled by the captive; excess cover is purchased through the conventional reinsurance market. Underwriting profit accrues to the captive (and hence to the parent group). Captives are managed by specialist captive management firms (Marsh Captive Solutions, Aon Captive & Insurance Management, WTW Captive Insurance, Artex), typically with a non-executive board including independent directors.
Single parent captive, group captive, sponsored captive, agency captive, cell captive within a PCC, micro-captive (US 831(b) election), branch captive, special purpose financial captive. The classification varies by jurisdiction.
A FTSE 100 UK retail group establishes “Group Insurance (Guernsey) Limited” as a single-parent captive. The captive writes UK employer’s liability and public liability cover for the group with a £5m retention per claim and reinsurance to £100m placed in Lloyd’s and Bermuda. Annual gross premium £25m, claims £18m, expenses £2m, retained underwriting profit £5m accruing to the group through the captive. Capital £45m held in the captive to satisfy regulatory requirements.
