"Except a shell company does generally have assets, IP and so on, when there is a bankruptcy, there is a chance the shareholders get something out of it." As far as I know (and I'm aware I don't that much), a bankruptcy means zero value left for the (ante-bankruptcy) owners. Whoever steps in has to (only) put in some value, like the government paying/writing off unsolvable debts, or the next owner that has to effectively buy the bankrupt entity from the government. Am I wrong?
