A captive insurance company is a private insurer that a parent company creates to cover its own risks. Instead of paying premiums to a traditional, third-party insurance carrier, the parent company pays them to its own captive. The captive then uses these funds to pay for any claims that arise.

The primary purpose is to gain more control over insurance programs. Businesses often face unique risks that commercial insurers either won't cover or will only cover at a very high price. A captive allows a company to tailor coverage specifically to its own needs. It also creates a direct financial incentive to manage risk effectively, since the parent company's money is on the line.

Not all captives are built the same way. The structure depends on the needs and resources of the parent organization. There are several common types, but most fall into a few main categories.

A single-parent captive is the most straightforward type, owned and controlled by one organization. A group captive is formed by multiple companies, often in the same industry, who team up to insure their collective risks. This spreads the risk and cost among the members.

A cell captive, sometimes called a Protected Cell Company (PCC), is a more flexible option. It consists of a central 'core' company that rents out individual cells to other businesses. Each cell is legally ring-fenced, meaning its assets and liabilities are kept separate from the other cells. This allows a company to get the benefits of a captive without the significant startup costs.

The decision to form a captive is a strategic one, aimed at achieving specific business goals. The benefits often go beyond simple insurance coverage.

One of the biggest draws is cost savings. In a good year with few claims, the profits that would have gone to a commercial insurer instead stay within the captive. These retained funds can be invested, generating additional income. Over time, this can lead to more stable and lower insurance costs.

Another key benefit is tailored coverage. Commercial insurance policies are standardized and may contain exclusions for risks specific to a certain industry. A captive can be designed to fill these gaps, providing coverage for things like cyber risk, environmental liability, or product recalls that might otherwise be unavailable or prohibitively expensive.

Finally, operating a captive enhances a company's overall risk management. Because the parent company has a direct financial stake in preventing losses, it becomes more focused on safety protocols, training, and loss control. This proactive approach can reduce the frequency and severity of claims over the long term.

Captive insurance companies are formal, licensed entities. They must be established in a specific location, known as a 'domicile,' which provides the regulatory framework for their operation. Domiciles can be onshore (like Vermont or Utah in the U.S.) or offshore (like Bermuda or the Cayman Islands). These locations have specific laws and regulations designed to support the captive industry.
