(1)    Time and place. Meetings of the board may be held from time to time as provided in the articles or bylaws at any location that the board selects or by any means described in sub. (2).

   (2)   Virtual meetings and attendance. Meetings of the board may be held by any means of communication through which the directors may simultaneously hear each other during the meeting. A director may participate in a meeting of the board at which other directors are physically present by any means of communication through which the director, all other directors so participating, and all directors physically present may simultaneously hear each other during the meeting. The number of directors physically present at a meeting, if any, shall be added to the number of directors otherwise participating in the meeting under this subsection to determine whether a quorum is present under s. 193.431, except that any director who objects at the beginning of the meeting to the transaction of business because the meeting is not lawfully called or convened and who fails to participate in the meeting after the objection may not be considered as present at the meeting for purposes of determining whether a quorum is present.

   (3)   Calling meetings and notice. Unless the articles or bylaws provide for a different time period and except as provided in s. 193.205 (3) and subs. (4) and (5), a director may call a board meeting by giving at least 10 days’ notice. The notice shall state the date, time, and place of the meeting, except that, if the meeting is held under sub. (2) and if no physical presence of directors at the meeting is intended, the notice shall so state. If required under this chapter, the articles, or the bylaws, the notice shall state the purpose of the meeting.

   (4)   Previously scheduled or adjourned meetings. If the day, time, and place of a board meeting are provided in the articles or bylaws, or announced at a previous board meeting, no notice of the meeting is required. Notice that an adjourned meeting will be reconvened need not be given other than by announcement at the meeting at which adjournment is taken.

   (5)   Waiver of notice and objection. A director may waive notice of a board meeting. A waiver is effective whether given before, at, or after the meeting, and whether given in writing, orally, or by attendance. Attendance by a director at a board meeting is a waiver of notice of that meeting, unless the director objects at the beginning of the meeting to the transaction of business because the meeting is not lawfully called or convened and does not participate in the meeting after the objection.

   (6)   Voting by absent directors. If the articles or bylaws so provide, a director may give advance written consent or opposition to a proposal to be acted on at a board meeting. If the director is not present at the meeting, consent or opposition to a proposal does not constitute presence for purposes of determining the existence of a quorum. If the proposal to be acted on at the meeting is substantially the same or has substantially the same effect as the proposal to which the director has consented or opposed, the consent or opposition shall be counted as the vote of a director present at the meeting in favor of or against the proposal and shall be entered in the minutes or other record of action at the meeting.
