What it means
The logic starts with a simple observation about commercial premiums. A large part of what a business pays covers the insurer's costs, commissions and profit margin, so a company with predictable, well managed losses is effectively paying someone else a fee to hold money it could hold itself.
Setting up a captive means creating a regulated insurance subsidiary, funding it with capital, and having group companies pay it premiums. The captive keeps the ordinary, frequent losses it can comfortably absorb and buys reinsurance for the rare, severe events that could otherwise sink it.
The benefits go beyond cost. A captive gives a business cover for risks the market prices badly or refuses outright, produces detailed claims data that sharpens risk management, and stops premiums swinging wildly with the wider insurance cycle.
There are real drawbacks. A captive needs genuine capital, professional management, actuarial support and regulatory compliance, and those fixed costs mean the structure rarely makes sense below roughly $1,000,000 to $2,000,000 of annual premium spend.
Tax authorities scrutinise captives closely, because a structure that shifts profit without transferring genuine risk is not insurance at all. A properly run captive charges arm's length premiums, holds adequate reserves and demonstrably takes on real risk, and treating it as a tax device rather than a risk vehicle is the fastest route to trouble.
In practice
Real-world examples.
Example
A hotel chain with sixty properties forms a captive to cover its own guest liability claims, retaining the first $250,000 of each claim and reinsuring above that. Detailed claims data from the captive shows two properties generating a third of all incidents, prompting targeted safety work.
Example
A haulage group finds commercial motor cover has doubled in three years despite an improving accident record. Its captive charges premiums based on its own experience rather than the sector average, cutting the annual cost by about a fifth.
Example
A pharmaceutical manufacturer cannot buy market cover for a specific product recall exposure at any sensible price. Its captive writes the cover internally, funded by annual premiums that build reserves over time, so a recall would be met from the group's own pool.
Think of it
“Captive is your own insurance company-insuring your own risks through a subsidiary.
Formula
Calculation
Annual saving from a captive = commercial premium - (expected claims + reinsurance cost + captive running costs)
A retail group currently pays $4,000,000 a year in commercial premiums for property and liability cover. Its actuary estimates expected annual claims of $2,400,000 based on ten years of history, reinsurance to cover losses above a retained layer costs $600,000, and running the captive costs $400,000 a year in management, fronting fees, audit and actuarial work.
Total captive cost = $2,400,000 + $600,000 + $400,000 = $3,400,000. The annual saving is $4,000,000 - $3,400,000 = $600,000.
The group must fund the captive with $2,000,000 of capital to satisfy its regulator, so the return on that committed capital is $600,000 / $2,000,000 = 30% a year, before counting any investment income the captive earns on reserves it holds between premium and claim.Case study
Seen in the real world.
This illustrative and fictional example concerns Wrenford Logistics, an invented freight operator paying $4,800,000 a year for motor and cargo cover. Its own claims averaged around $2,600,000 a year with very little variation, and the fictional finance director calculated that roughly $2,200,000 of the premium was funding somebody else's costs and profit.
Wrenford formed a captive in the story with $2,500,000 of capital, retaining the first $500,000 of each claim and reinsuring above that for $700,000 a year. With running costs of $450,000, the invented total came to $3,750,000 against the previous $4,800,000, a saving of $1,050,000 in year one.
The unexpected benefit in this illustrative account was behavioural. Because depot managers now saw claims charged directly to their own results, reported incidents fell by nearly a fifth in two years, and the captive's reserves grew faster than the actuary had projected.
Watch out
Common mistakes.
- Setting up a captive mainly for tax reasons, which invites challenge and misses the risk management benefits that make the structure worthwhile.
- Underestimating the fixed running costs, so a business with modest premium spend spends more on administration than it ever saves.
- Retaining too much risk in the captive without adequate reinsurance, leaving the group exposed to a single catastrophic claim.
Questions
People also ask.
What size of business needs a captive?
As a rough guide, groups spending upwards of $1,000,000 to $2,000,000 a year on premiums, with reasonably predictable losses and the capital to fund the structure.
Is a captive the same as self insurance?
It is a formalised version of it, with a licensed company, real capital, actuarial reserving and the ability to buy reinsurance, rather than simply paying claims from trading cash.
What is a fronting arrangement?
It is where a licensed commercial insurer issues the policy paperwork and passes the risk to the captive, which is often needed where local law requires an admitted insurer.
