Captive Insurance

An insurance company wholly owned by the entity or group it insures, created to fund the owner's own risks rather than transfer them to a commercial carrier.

FAQs

What size organization justifies forming a captive?
As a general benchmark, organizations spending $500,000 or more annually in commercial insurance premiums begin to find captive feasibility studies worthwhile. However, size alone is not determinative—the predictability and homogeneity of the risk, the organization's loss history, and its appetite for retained risk matter at least as much as premium volume.
What are the IRS concerns about captive insurance?
The IRS has identified abusive micro-captive transactions—typically small captives electing Section 831(b) tax treatment—on its 'Dirty Dozen' list of tax schemes. The concerns involve captives that don't operate as genuine insurance companies, charge inflated premiums, cover implausible risks, or exist primarily for tax avoidance rather than legitimate risk management. Legitimate large captives with genuine risk transfer and distribution are generally well-established.
Can a captive write risks for unrelated third parties?
Yes, but doing so changes the captive's regulatory status—it may need broader licensing as a commercial insurer. Some captives write a limited percentage of unrelated business to satisfy the IRS 'insurance risk distribution' requirement. Writing significant third-party business converts the captive into something closer to a commercial carrier and brings additional regulatory obligations.

Captive insurance is a formal self-insurance arrangement in which an organization creates its own licensed insurance subsidiary to underwrite the risks of the parent or affiliated entities. Rather than paying premiums to a third-party commercial insurer, the parent pays premiums to its captive, which accumulates reserves and pays claims—retaining underwriting profit within the corporate group.

How It Works / Why It Matters

Captive insurance sits at the intersection of risk management, corporate finance, and insurance regulation. The captive is a genuine insurance company—it must be licensed in its domicile, maintain minimum capitalization, file annual statements, and satisfy regulatory requirements. What distinguishes it from commercial insurance is ownership: the insured owns the insurer.

The primary motivations for forming a captive include:

Cost reduction: Commercial insurers price to cover all policyholders and earn profit. A large organization with favorable loss experience may pay far more in commercial premiums than it collects in claims. A captive allows the owner to retain underwriting profit.

Access to reinsurance markets: Commercial insurance and reinsurance are separate markets with different pricing dynamics. A captive can access reinsurance markets directly—sometimes obtaining broader coverage at lower cost than available in the primary market.

Coverage customization: Captives can provide coverage for risks that commercial markets exclude or price prohibitively—cyber-specific coverages, supply chain risks, reputational harm, or emerging perils.

Risk management discipline: The captive structure makes the true cost of risk visible and internal, creating financial incentives for loss prevention programs that may be absent when risk is fully transferred to a commercial carrier.

In Practice

Pure captive: A Fortune 500 manufacturer creates a wholly-owned captive in Vermont to insure its workers' compensation, general liability, and property exposures. The captive reinsures the excess above its retention with commercial reinsurers. After five years of favorable loss experience, the captive has accumulated significant surplus that remains within the corporate group.

Group captive: Fifty mid-sized trucking companies form a group captive to share commercial auto liability risk. None is large enough individually to justify a pure captive, but together they have sufficient homogeneous exposure to make the structure viable. Members share losses (and profits) based on their individual loss experience.

Rent-a-captive and protected cell companies (PCCs): Organizations that want captive economics without full ownership costs can rent a cell within a PCC, a structure where each participant's assets and liabilities are legally segregated. Common in offshore domiciles such as Guernsey and the Cayman Islands.

Domicile selection is a critical decision. Vermont is the largest US captive domicile, with over 1,000 licensed captives. Other major US domiciles include Delaware, Hawaii, Utah, and Tennessee. Offshore domiciles—Bermuda, Cayman Islands, Guernsey—offer more regulatory flexibility but require additional compliance considerations for US-based parents.

Captives interact directly with fronting-carrier arrangements when the captive needs admitted paper for state-regulated lines. Actuarial support is essential, and firms like Verisk provide underlying data analytics used in captive loss projections.

Related Concepts

Captive insurance connects to fronting-carrier (providing admitted paper), risk-retention-group (an alternative self-insurance structure), and quota-share (the reinsurance mechanism captives typically use to buy excess protection).
