Facultative Reinsurance
Also known as: fac reinsurance, facultative cover
Facultative reinsurance is reinsurance arranged one risk at a time. The word 'facultative' means the reinsurer has the faculty — the option — to accept or reject each individual policy offered to it. This contrasts with treaty coverage, where the reinsurer must automatically take every risk that falls within the agreement. Because each submission is underwritten on its own merits, facultative deals are used for large, unusual, or high-hazard exposures that fall outside the primary carrier's normal treaty terms.
For a small-business buyer, facultative reinsurance is usually invisible, but it explains why an insurer can sometimes say 'yes' to a risk that looks too big or too odd for its standard appetite — a landmark building, an unusual manufacturing operation, or a very high per-occurrence limit. The primary carrier shops that single account to a reinsurer, secures backing, and issues the policy. The tradeoff is time and cost: facultative placement is labor-intensive, so it can slow down binding and add expense that may show up in the quoted premium.
A practical nuance is how facultative fits alongside a carrier's treaty reinsurance. Insurers often use treaties for the bulk of routine business and reserve facultative for the exceptions that spill over treaty limits or violate treaty exclusions. Facultative can be written proportionally (sharing premium and loss by percentage, sometimes with a ceding commission) or on an excess-of-loss basis above an attachment point. Because it is negotiated deal by deal, terms and pricing vary widely, making it the most flexible — but also the least efficient — form of reinsurance.
Real-world scenario
Cascade Mutual, a regional insurer, is asked to write a $25,000,000 commercial property policy for Bishop Cold Storage, a refrigerated-warehouse operator. The exposure is far larger than Cascade's normal appetite: its property treaty reinsurance only automatically covers risks up to $10,000,000, and Cascade is comfortable keeping just $5,000,000 net on any single building. Rather than decline the account, Cascade's underwriting team shops this one specific risk to a reinsurer on a facultative basis.
The reinsurer agrees to accept the $20,000,000 layer of exposure sitting above Cascade's $5,000,000 retention, so together the two parties cover the full $25,000,000 limit. The facultative reinsurance premium is $340,000 for the year, and the reinsurer pays Cascade a 25% ceding commission of $85,000 to offset Cascade's acquisition costs. Bishop's own policy carries a $100,000 deductible and an annual direct premium of $410,000.
Eight months later an ammonia-line failure sparks a fire, producing an $18,500,000 building loss plus $420,000 in adjustment and legal expense. After Bishop's $100,000 deductible, the covered loss is $18,400,000. Because the facultative contract sits above Cascade's $5,000,000 retention, Cascade funds the first $5,000,000 and the reinsurer reimburses the remaining $13,400,000, plus its pro-rata share of the $420,000 expense (about $306,000, in proportion to its 72.8% share of the loss). Without the $20,000,000 facultative placement, a single $18,400,000 claim would have consumed nearly Cascade's entire $22,000,000 surplus; instead its net loss is capped near $5,000,000, and it still booked the $410,000 direct premium to write an account it otherwise could never have touched.
How it affects your premium
Facultative reinsurance is priced one risk at a time, so the ceding insurer and reinsurer negotiate each placement individually. The cost of ceding a single large or unusual exposure turns on these drivers:
- Size of the ceded limit above retention — the more capacity the reinsurer accepts above the insurer's net attachment point, the higher the facultative premium.
- Underlying hazard class — cold storage, chemical, woodworking and other high-fire or high-severity occupancies command steeper rates than a low-hazard office building.
- Original policy terms — because most facultative certificates follow form to the original policy, broad manuscript wording, low deductibles, and rich business income limits raise the reinsurer's exposure and price.
- Ceding commission negotiated — a higher ceding commission paid back to the insurer effectively increases the net cost of the cession to the reinsurer, which is reflected in the gross rate.
- Loss history of the specific account — a bad loss run on the individual risk being ceded pushes pricing up, since facultative underwriting examines that one account in detail.
- Catastrophe and accumulation exposure — coastal wind, wildfire, or earthquake aggregation in the reinsurer's own book can add a load to any single ceded property.
- Reinsurer financial strength and market conditions — a highly rated reinsurer in a hard market charges more for scarce capacity than in a soft market.
Common misconceptions
Myth: Facultative reinsurance protects the policyholder if the insurer goes broke.
Reality:
The facultative contract is strictly between the ceding insurer and the reinsurer; the policyholder has no direct claim against the reinsurer and instead relies on the state guaranty fund if its carrier becomes insolvent.
Myth: Facultative and treaty reinsurance are basically the same thing.
Reality:
They are not — treaty reinsurance automatically covers a whole class of business under one negotiated contract, while facultative reinsurance is optional and negotiated risk by risk for individual accounts that fall outside the treaty.
Myth: Buying facultative reinsurance means the insurer thinks the account is a bad risk.
Reality:
More often it simply means the requested limit exceeds the insurer's normal attachment point or treaty capacity, so the carrier cedes the excess to write a perfectly good account it would otherwise have to decline.
Frequently asked questions
Who actually buys facultative reinsurance — the business or the insurance company?
The insurance company buys it. Facultative reinsurance is a transaction between your insurer and a reinsurer; as the policyholder you typically never see it and it does not change the coverage on your declarations page.
Does facultative reinsurance change what my policy covers?
No. Because most facultative certificates follow form to your underlying policy, your coverage, limits, and exclusions stay exactly the same — the reinsurance only shifts who ultimately pays part of a large loss.
How is facultative reinsurance different from treaty reinsurance?
Facultative is negotiated one risk at a time and can be accepted or declined individually, whereas treaty reinsurance automatically covers an entire book of similar policies under a single standing agreement.
Why would my carrier need facultative reinsurance for my policy?
Usually because your requested limit is larger than the carrier's normal net retention or its treaty capacity, so it cedes the excess to a reinsurer instead of turning your account away.
Does using facultative reinsurance make my premium go up?
Not directly. The reinsurance cost is part of the insurer's underwriting economics; your premium is driven by your own exposures and limits, though very large or catastrophe-prone risks can cost more overall.
