Wisconsin Statutes Corporations (Ch. 180 to 188) § 181.0831. Director conflict of interest

(1) When contract or transaction is not void or voidable. No contract or other transaction between a corporation and a director, or any entity in which a director is a director or officer or has a material financial interest, is void or voidable because of the relationship or interest or because the director is present at the meeting of the board or a committee that authorizes, approves or ratifies the contract or transaction or because the director's vote is counted for that purpose, if any of the following applies:

(2) Quorum requirements. Common and interested directors may be counted in determining the presence of a quorum at a meeting of the board or a committee that authorizes, approves or ratifies a contract or transaction under sub. (1).

(3) Additional requirements. The articles of incorporation, the bylaws or a resolution of the board may impose additional requirements on conflict of interest transactions.
