S.C. Code Ann. § 9-1-1830

Starting July 1, 1981, there must be paid to the system, and credited to the post-retirement increase special fund, contributions by the employers in an amount equal to two-tenths of one percent of the earnable compensation of each member employed by each employer. In addition, the board, on the recommendation of the actuary, shall transfer a portion of the monies as are received pursuant to Section 9-1-1050 that are available due to actuarial gains in the system if the transfers do not adversely affect the funding status of the system. Starting July 1, 1986, all contributions previously credited to the post-retirement increase special fund must be diverted and credited to the employer annuity accumulation fund.
