As applicable, an insurer that issued a reimbursement insurance policy shall not terminate the policy until a notice of termination in accordance with RCW 48.18.290 has been given to the service contract provider or protection product guarantee provider and has been delivered to the commissioner. The termination of a reimbursement insurance policy does not reduce the issuer’s responsibility for service contracts issued by service contract providers or protection product guarantees issued by protection product guarantee providers prior to the effective date of the termination.
