It depends on what the overall market place is though... not just that single company. Maybe someone did an analysis of the market and determined that if Hostess folded, X number of assets will be bought, Y number of products will be sold, and the Z number of bakers will be re-employed by the new company(s).
I have no idea - but it's not unreasonable for a group of people to determine that their overall economic well being is better if the company folds.
