S.C. Code Ann. § 38-21-250
(1) Transactions within a holding company system to which an insurer subject to registration is a party are subject to the following standards:
(2) The following transactions involving a domestic insurer and any person in its holding company system may not be entered into unless the insurer has notified the department in writing of its intention to enter into the transaction at least thirty days prior thereto, or such shorter period as the director or his designee may permit, and the director or his designee has not disapproved it within such period:
(i) sales, purchases, exchanges, loans, or extensions of credit, guarantees, or investments if the transactions are equal to or exceed:
(ii) loans or extensions of credit to any person who is not an affiliate, where the insurer makes the loans or extensions of credit with the agreement or understanding that the proceeds of the transactions, in whole or in substantial part, are to be used to make loans or extensions of credit to, to purchase assets of, or to make investments in, any affiliate of the insurer making the loans or extensions of credit as long as such transactions are equal to or exceed:
(v) any material transactions, specified by regulation of the department, which the director or his designee determines may adversely affect the interests of the insurer's policyholders.
Nothing herein authorizes or permits any transactions which, in the case of an insurer, not a member of the same holding company system, would be otherwise contrary to law.
