Key is to determine what do they want to look like. (presume this is already figured out)
Next comes selling the other bits off to get to a point that when you go into bankruptcy you have a chance of coming out of it with the debt shed and have creditors have faith in your new model to again back you.
That said, given the shape of the company and the lack of cleaning house as they have now been called out on, do not see this coming out of bankruptcy with current management at the helm and you are also likely correct that they will walk away no worse and actually with a good payout.
Men and women in the field are the ones who are going to take the hit. They should hope they are with one of the groups that get sold in advance of this turd flushing and perhaps their new company/management will have a clue.
