An insurance company that is licensed by a state's insurance department to do business in that state. Admitted carriers must comply with state regulations including rate and form approval requirements, financial solvency standards, and market conduct rules. Their policies are backed by the state guaranty fund, which provides protection to policyholders in the event of insurer insolvency. Admitted carriers file rates and policy forms with state regulators for approval before use. They are subject to regular financial examinations and must meet ongoing reporting requirements. The admitted market represents the standard insurance marketplace, as distinguished from the surplus lines (non-admitted) market.
