S.C. Code Ann. § 59-69-120

Whenever any such reserve fund reaches an amount sufficient to put the county or school district, as the case may be, on a cash basis, the fund may be used for said purpose. And in each year during the time necessary to create such reserve fund, the county superintendent of education shall use the fund accumulated as a loan, without interest, to pay claims held by teachers to whom pay certificates were originally issued, the funds so used to be replaced annually from taxes collected for school purposes.
