Insurance placed with carriers not licensed (admitted) in the state where the insured risk is located. Non-admitted insurers, also called surplus lines insurers, are not subject to state rate and form approval requirements, giving them flexibility to underwrite unique or high-risk exposures. However, they must meet financial requirements and be listed on the state's approved eligible surplus lines insurer list. Non-admitted policies are not protected by state guaranty funds in the event of insurer insolvency, though historical insolvency rates for surplus lines carriers are low. Non-admitted insurance can only be placed after a surplus lines broker conducts a diligent search in the admitted market and documents that coverage is not available from admitted carriers.
