S.C. Code Ann. § 38-19-410: Contingent liability of members.

Each member of a domestic mutual insurer, except as otherwise provided in this chapter, has a contingent liability, prorata and not one for another, for the discharge of its obligations. The contingent liability is, at a maximum, the amount stated in the insurer's articles of incorporation but may not be less than one nor more than five additional premiums for the member's policy at the annual premium rate. Every policy issued by the insurer shall contain a statement of the contingent liability. Cancellation of the policy of a member does not relieve the member of contingent liability for his proportion of the obligations of the insurer which accrued while the policy was in force.
