Section 133.06 - Interlocking directorates(1) No corporation with its principal place of business in this state may elect or appoint any person as a director or permit any person to serve as a director, if: (a) That person was at the same time a director of any other corporation; and(b) Either corporation has capital, surplus and undivided profits aggregating more than $100,000. In this paragraph, the amount shall be determined by the aggregate amount of the capital, surplus and undivided profits, exclusive of dividends declared but not paid to stockholders, at the end of the fiscal year of the corporation next preceding the election of directors; and(c) Such corporations are, or have been, by virtue of their business and location of operation, competitors, so that the elimination of competition by agreement between them would violate this chapter.(2) If a corporation has lawfully elected or appointed a director, the corporation may permit the director to serve in such capacity for one year thereafter, notwithstanding sub. (1). This section shall not apply to any corporation chartered by the federal government if its selection of directors is exempt from state law, but a person may be deemed ineligible for the service on the board of any corporation not so exempt because of concurrent service on the board of an exempt corporation.(3) Any corporation violating this section may be enjoined from permitting such person to serve as a director and from doing business in this state, so long as such violation continues.(4) This section does not apply to the insurance business.1979 c. 209; 1983 a. 215.
