(a) If a reciprocal insurer has a surplus of assets over all liabilities at least equal to the minimum capital stock required of a domestic stock insurer authorized to transact like kinds of insurance, then, upon application of the attorney and as approved by the subscribers' advisory committee, the Insurance Commissioner shall issue his or her certificate authorizing the insurer to extinguish the contingent liability of subscribers under its policies then in force in this state and to omit provisions imposing contingent liability in all policies delivered or issued for delivery in this state for so long as all the surplus remains unimpaired.
(b) Upon impairment of the surplus, the commissioner shall forthwith revoke the certificate. The revocation shall not render subject to contingent liability any policy then in force and for the remainder of the period for which the premium has theretofore been paid. However, after the revocation, no policy shall be issued or renewed without providing for contingent assessment liability of the subscriber.
