S.C. Code Ann. § 33-47-940: Officers.

The directors shall elect from their number a president and one or more vice-presidents. They shall also elect a secretary and treasurer who need not be directors and they may combine the two latter officers and designate the combined office as secretary-treasurer. The treasurer, who shall be a bonded official, may be a bank or any depository and as such shall not be considered as an officer but as a function of the board of directors. In such case the secretary shall perform the usual accounting duties of the treasurer except that the funds shall be deposited only as authorized by the board of directors.
