A. The Commission may issue a certificate authorizing the reciprocal to reduce or extinguish the contingent assessment liability of subscribers under its policies then in force in this Commonwealth, and to omit provisions imposing contingent assessment liability in all policies delivered or issued for delivery in this Commonwealth for as long as all such surplus to policyholders remains unimpaired. The certificate may be issued if, in the case of a domestic or foreign reciprocal, the reciprocal has surplus to policyholders of at least four million dollars, or, if in the case of an alien reciprocal, the reciprocal has a trusteed surplus, as defined in § 38.2-1031, of at least four million dollars. No certificate may be issued until an application of the attorney has been approved by the subscribers' advisory committee. However, any reciprocal that on June 30, 1991, was authorized to issue and was engaged in issuing policies without contingent liability may continue to do so until July 1, 1994, by maintaining at all times the minimum surplus to policyholders if a domestic or foreign reciprocal, and the minimum trusteed surplus if an alien reciprocal, required at the time of authorization.
