And two more lawsuits concerning the same matter are pending in Alabama with similarly astronomical damages claims. Plus it looks like PwC isn't going to appeal its way out of paying the MF Global damages. All this is to say, has anybody done the math to see at what point PwC has to pull a Gawker and go chapter 11?
