I think it is a given. Tate has to finish off any scheduled meetings she already had.
It would look very bad if she told NAB and GTP "Oh, I am cancelling your meeting where you wanted me to hear your concerns (even though you have told me the same speil 957 times in the last 18 months) because I have already voted in favor of the merger."
She has to finish off her meetings that were scheduled already, so she can say that she listened to everyone and formed her own opinion.
I would expect to hear something from her or one of her aids early next week.
