PWC has already showed it's hand. They need & want to get paid. So far they have not had any great success. Recent settlement shows that of the $6mm supposedly due them PWC settled for 1/6th.
HLNT appears to have the same settlement offer at hand should they decide to simply move on. However, it does not appear that HLNT will take it as I'm sure they feel they can do better!
Moreover, business also appears to have improved to the point of rendering a settlement subsequent costs rather irrelevant to the bigger-picture.
