There is a restructuring slide deck up on the website now next to each of the debt tranches.
The senior tranche is getting swapped for new bonds that pay more interest but at about 1:2 face value of existing debt, and some equity in the new business is coming to us (not sure how WA deals with that!).
The subordinated tranche is essentially getting wiped out. I think it said they get 1% in cash back.
