S.C. Code Ann. § 38-9-140

When the principal of any securities deposited under Sections 38-9-80 to 38-9-140 is paid to the director or his designee, he shall pay the money so received to the company. However, if the securities were required to be deposited under Section 38-9-80 the payment may not be made until the company deposits an equal amount of other securities of the character required for similar deposits. If the company fails to deliver to the director or his designee within thirty days after receiving notice of this requirement the securities necessary to maintain its required deposit, he may invest the money in other securities of the required character and hold the same as he held those which were paid.
