S.C. Code Ann. § 33-31-805: Terms of directors generally.

(a) The articles or bylaws may specify the terms of directors. Except for designated or appointed directors, the terms of directors may not exceed five years. In the absence of a term specified in the articles or bylaws, the term of each director is one year. Directors may be elected for successive terms.

(b) A decrease in the number of directors or term of office does not shorten an incumbent director's term.

(c) Except as provided in the articles or bylaws:

(1) the term of a director filling a vacancy in the office of a director elected by members expires at the next election of directors by members; and

(2) the term of a director filling another vacancy expires at the end of the unexpired term that such director is filling.

(d) Despite the expiration of a director's term, the director continues to serve until the director's successor is elected, designated or appointed, and qualifies, or until there is a decrease in the number of directors.
