This stuff doesn’t require the CEO or CFO either. Receivership doesn’t even require the active participation of the board, so yes there’s some benefit of keeping existing executives around but that’s often offset by the costs of doing so.
How would it possible help in this situation? The game is over and everyone knows exactly where all the money is. It will just be distributed back to the creditors and then remaining to the shareholders. Who needs the CFO for that? Basically anyone could run that process.
