"This is a big issue that needs to be thought through carefully and we want the board to come to all shareholders and give a chance to have their voice heard."
ISS, which issues recommendations on how shareholders should vote on proxy proposals, generally believes the "bundling" of proposals was not in the best interest of shareholders, but supported the elimination of "blank check" preferred shares due to their potential to be misused as a takeover defense.

Few lawsuits have ever been filed challenging proposals under the rules, a situation some legal experts attributed to the normally passive nature of shareholders.
