S.C. Code Ann. § 38-19-630: Repayment of loans.

The insurer may repay the loan only out of its realized net earned surplus in excess of the minimum surplus required for the kinds of insurance transacted. This loan may not be repaid out of borrowed money. The insurer shall repay the loan or a part of it when its realized net earned surplus has become adequate to repay without impairing the insurer's operations.
