This is what confuses me as well.The part I can't wrap my mind around is the $40 billion they have from selling spectrum to Space X ($17 billion) and AT&T ($23 billion). The FCC approved this last month, so I can't connect the dots on the bankruptcy piece of things. $40 billion doesn't sound like a company that needs to file Chapter 11 bankruptcy.
The only thing I can think of is they are trying to file before they get the money so many of their debts go away because of the bankruptcy. But from everything I see reported online they are really cash positive.
