Wisconsin Statutes Corporations (Ch. 180 to 188) § 180.0806. Staggered terms of directors

The articles of incorporation or the bylaws, if the articles of incorporation so provide, may provide for staggering the terms of the directors by dividing the total number of directors into 2 or 3 groups. In that event, the terms of directors in the first group expire at the first annual shareholders' meeting after their election, the terms of the 2nd group expire at the 2nd annual shareholders' meeting after their election, and the terms of the 3rd group, if any, expire at the 3rd annual shareholders' meeting after their election. At each annual shareholders' meeting held thereafter, the number of directors equal to the number of the group whose term expires at the time of the meeting shall be chosen for a term of 2 years, if there are 2 groups, or a term of 3 years, if there are 3 groups.
