(a) Except as provided otherwise in § 4916 of this title with respect to nonassessable policies, each member of a domestic mutual insurer shall have a contingent liability, pro rata and not one for another, for the discharge of its obligations, which contingent liability shall be in such maximum amount — not less than 1 nor more than 6 times the premium for the member's policy at the annual premium rate — as shall be specified in the insurer's certificate of incorporation or bylaws.
(b) Every policy issued by the insurer shall contain a statement of the contingent liability.
(c) Termination of the policy of any such member shall not relieve the member of contingent liability for such member's proportion of the obligations of the insurer which accrued while the policy was in force.
(d) Unrealized contingent liability of members does not constitute an asset of the insurer in any determination of its financial condition.
