Guaranty fund

A state-created safety net that pays covered claims, up to statutory limits, when an admitted insurer becomes insolvent.

Also called: state guaranty association, insurance guaranty fund, guaranty association, security fund

A guaranty fund is a state association that steps in to pay covered claims when a licensed (admitted) insurer is declared insolvent. Every state has one for property and casualty insurance. Member insurers fund it. In almost every state, the money is raised by assessing the insurers still operating, after a failure occurs, and many states let insurers recoup those assessments through premium tax offsets or policy surcharges.

The protection is limited. According to the National Conference of Insurance Guaranty Funds, most states cap property and casualty claims at $300,000, though caps generally do not apply to workers' compensation claims, and limits depend on each state's statute. A business with a claim above the cap files for the excess against the failed insurer's estate and may recover only part of it.

Eligibility is the bigger trap. Guaranty funds generally do not protect policyholders of surplus lines (non-admitted) insurers, and risk retention groups typically sit outside the system, so buying from one of them means relying on the carrier's own strength. Check the carrier's financial strength rating and admitted status before you bind. The guide on what happens when an insurer fails: guaranty funds and business policies describes the liquidation process, and the non-admitted insurer entry covers the gap.
