@Flatt: The $310 million kill fee is a fact, according to what I read in the SEC documents. But just to be clear, that fee would be inherited, and therefore paid, by the acquiring company. So it is simply a question of whether another suitor wants to tack the $310 million kill fee onto whatever additional money it is willing to pay over the $56.25 share price. I am not saying or predicting that will happen but I am not as confident as others that another company won't make a play here. The jury is out on that possibility and there is no reason I am aware of why it has to come this week. Or next week, for that matter.
@uptab: Your "wait mode" notion seems likely to be true and I would add that it is possible there were possible buyers from institutions or funds whose hands were tied by the sub $1 share price who are now able to jump in. Possibly your comment included that thought as well.
