Special Shareowner Meetings
RESOLVED, Shareowners ask our board to take the steps necessary to amend our bylaws and each appropriate governing document to give holders of 10% of our outstanding common stock (or the lowest percentage allowed by law above 10%) the fullest power to call special shareowner meetings consistent with state law.
Special meetings allow shareowners to vote on important matters, such as electing new directors, that can arise between annual meetings. If shareowners cannot call special meetings investor returns may suffer. Shareowners should have the ability to call a special meeting when a matter merits prompt consideration.
