S.C. Code § 59-71-550
The proceeds of the sale of State school bonds shall be received by the State Treasurer and placed by him to the credit of the State Board of Education, except that the premium, if any, shall be placed in the sinking fund established by Section 59-71-570 and the accrued interest, if any, shall be used to discharge in part the first interest to become due on such bonds. On the occasion that he receives the proceeds of State school bonds from the purchasers, the State Treasurer shall segregate that part of the proceeds which are intended for allocation to school districts for capital improvements and other purposes from that portion intended for the purchase of school bus equipment, but the purchasers of such bonds shall in no wise be liable for the proper application of the proceeds to the purposes for which they are intended.
The State Board of Education shall in turn credit each of the several school districts with its proportionate share of the proceeds of the bonds applicable to capital improvements and other purposes, each district's share being determined in the ratio of its public school enrollment to the enrollment of the State as a whole.
