What Is a Captive Insurance Company?
A captive insurance company is a licensed insurance company formed by a business or group of businesses to insure the risks of its owners. Rather than paying premiums to a commercial insurer and hoping for favorable claims experience, the captive owner retains the underwriting profit when losses are below expectations and builds equity in the captive over time.
Captives are not a fringe strategy — they are used by the majority of Fortune 500 companies and an increasing number of mid-market businesses. According to the Captive Insurance Companies Association (CICA), there are more than 7,000 captive insurance companies worldwide, holding over $100 billion in assets.
Types of Captive Structures
The most common captive structures include:
- Single-parent (pure) captive: Owned by one company, insures only that company's risks — maximum control and customization
- Group captive: Owned by multiple unrelated companies in the same industry — lower entry cost, shared risk pool
- Association captive: Sponsored by a trade association for its members — similar to group captive with association governance
- Cell captive (protected cell company): A single captive with segregated cells for different owners — lower cost than a standalone captive
- Risk retention group (RRG): A special type of group captive for liability risks, governed by federal law
Is Your Business a Good Captive Candidate?
Not every business is a good captive candidate. The economics of a captive work best for organizations with predictable, manageable losses; sufficient premium volume to justify the administrative costs; and the financial capacity to fund the captive's initial capitalization.
- Annual insurance premiums of $500K or more (single-parent captive) or $250K+ (group captive)
- Consistent, predictable loss history over 3–5 years
- Strong risk management program with documented safety practices
- Financial capacity to capitalize the captive (typically 25%–50% of annual premium)
- Management commitment to a multi-year program
- Industries with favorable loss experience: construction, real estate, healthcare, technology
Financial Benefits of Captive Insurance
The primary financial benefit of a captive is the retention of underwriting profit. When a business pays premiums to a commercial insurer, the insurer retains the profit if losses are below the premium. In a captive, that profit stays within the business.
Additional financial benefits include: investment income on captive reserves, potential tax advantages (premiums paid to a captive may be deductible as ordinary business expenses), improved cash flow from lower net insurance costs, and access to reinsurance markets at rates typically available only to insurance companies.
Coverage Advantages of Captive Programs
Captives can provide coverage that the commercial market either will not write or prices prohibitively. This includes coverage for high-frequency, low-severity losses that commercial insurers exclude; coverage for emerging risks that the commercial market has not yet priced; and customized policy terms that match the specific risk profile of the business.
For businesses in industries with limited commercial market appetite — cannabis, social services, certain construction specialties — a captive may be the only viable path to comprehensive coverage at sustainable cost.
Domicile Selection and Regulatory Considerations
Captives are licensed by state insurance regulators. Popular U.S. domiciles include Vermont (the largest U.S. captive domicile), Delaware, Hawaii, and Utah. Offshore domiciles — Cayman Islands, Bermuda, Barbados — offer regulatory flexibility but require careful tax planning.
New York businesses can form captives in any domicile, but must comply with New York insurance regulations for risks located in New York. Working with a captive manager and insurance counsel experienced in New York captive regulations is essential.
