Captive insurance sits between traditional commercial insurance and informal self-insurance. A business still funds its own risk, but it does so through a licensed insurance entity with formal underwriting, reserving, governance and reporting responsibilities.
The NAIC describes a captive in its simplest form as a wholly owned subsidiary created to provide insurance to its non-insurance parent company or companies. Captives can insure many types of risk, but they are not a shortcut around insurance regulation. Once established, a captive operates as an insurance company and is subject to the rules of its domicile.
How a captive works
Imagine a company that pays several million dollars each year for commercial insurance. Management may decide that predictable layers of certain losses can be retained, while catastrophic volatility should still be transferred. The company can form a captive, capitalise it, charge actuarially supportable premiums and use the captive to pay covered claims.
The captive may then purchase reinsurance to protect against severe or accumulated losses. That creates a layered risk-financing structure: the operating company transfers selected risk to its captive, and the captive may transfer part of that risk to reinsurers.
Common captive structures
| Structure | Basic idea |
|---|---|
| Pure or single-parent captive | Owned by one parent and primarily insures risks of that parent and affiliates. |
| Group or association captive | Multiple organisations with similar risk needs participate together. |
| Sponsored or protected-cell structure | Participants access segregated cells within a larger captive platform, subject to local law. |
| Risk retention group | A specialised U.S. liability risk vehicle owned by members with similar exposures and governed by a distinct federal/state framework. |
Why companies consider captives
- Control over retained risk. A captive can create a formal structure for risks a company already expects to fund.
- Coverage design. The owner may be able to tailor wording and limits to its own risk profile, subject to regulatory and actuarial requirements.
- Access to reinsurance. A captive can be a vehicle for purchasing reinsurance or other risk-transfer protection.
- Data and loss prevention. Retaining risk can create stronger incentives to improve claims data, safety and prevention.
- Long-term risk financing. Strong years may help build reserves for future insured losses, depending on the captive’s structure and rules.
What a captive does not eliminate
A captive does not make risk disappear. The owner is moving risk into an insurance company that it ultimately owns. Poorly priced coverage, weak reserves or concentrated losses can damage the captive and potentially require additional capital. Governance, actuarial work, claims management, investments, compliance and reinsurance all matter.
When does a captive make sense?
There is no universal premium threshold. The decision depends on loss history, volatility, commercial-market pricing, the organisation’s balance sheet, available capital, administrative costs and whether the company has enough risk-management maturity to run an insurance vehicle.
For smaller businesses, a stand-alone captive can be disproportionate. Group, sponsored or cell-based solutions may reduce some barriers, but they also introduce counterparty, governance and participation questions that require due diligence.
Tax should not be the only reason
Captives can have tax consequences, but a credible captive should begin with a real insurance and risk-financing purpose. Tax treatment depends on jurisdiction, ownership, risk distribution and other facts. Businesses should obtain specialist legal, tax, actuarial and regulatory advice rather than treating a captive as a generic tax product.
Frequently asked questions
Is a captive the same as self-insurance?
A captive is a form of structured self-insurance, but it is also a regulated insurance entity with capital, reserving and reporting obligations.
Can a captive insure third-party risks?
Some structures can, depending on licensing, domicile and business plan. A pure captive is usually focused on parent and affiliate risks.
Does a captive replace commercial insurance?
Not necessarily. Many captive programmes combine retained risk with commercial insurance and reinsurance.
