S.C. Code Ann. § 38-77-520
No automobile insurer may be licensed to transact automobile insurance in this State unless it becomes a participating member of the facility with respect to automobile insurance and thereafter continues participation so long as it transacts automobile insurance in this State. Every member is bound by the plan of operation of the facility as approved or promulgated by the director or his designee and by any rules the governing board of the facility lawfully prescribes.
If the authority of an insurer to transact automobile insurance in this State terminates for any reason its obligations as a member of the facility nevertheless continue until all obligations have been fulfilled and the director or his designee has so found and certified to the governing board of the facility.
If an insurer merges into or consolidates with another insurer authorized to transact automobile insurance in this State, or another insurer authorized to transact automobile insurance in this State has reinsured the insurer's entire automobile insurance business in this State, both the insurer and its successor or the assuming reinsurer, as the case may be, are liable for the insurer's obligations in respect to the facility.
Any unsatisfied net liability to the facility of an insolvent insurer which is a member of the facility must be assumed by and apportioned among the remaining members in the same manner in which assessments or gain and loss are apportioned. The facility thereupon acquires and has all rights and remedies allowed by law in behalf of the remaining members against the estate or funds of the insolvent insurer for sums due the facility.
