S.C. Code Ann. § 38-9-130

The director or his designee at the time of receiving any bonds or other securities deposited under Sections 38-9-80 to 38-9-140 shall give to the company authority to collect the interest thereon for its own use. This authority continues in force until the company fails to pay any of its liabilities for which the deposit is security. In case of that failure the party charged with payment of the interest must be notified that thereafter the interest is payable to the director or his designee to be applied, if necessary, to the payment of those liabilities.
