Reinsurance is an agreement between two insurers, where one transfers portions of its risks portfolios to reduce the chances of paying a large insurance claim. In this model, the reinsurer is the second business and is responsible for clearing the claims that arise from the first company.
In the dealership world, reinsurance is a separate company owned by you, the dealer, and is in charge of providing vehicle service contracts, certified pre-owned programs, GAP, warranties, and collateral programs for your clients without involving the services of third-party insurance.
