I don't know why they would keep Perez.
What has he done to make anyone want to keep him? He's ridden along with the company as it spiraled down into bankruptcy, for most of that time assuring everyone that the company was ready to turn around. So why would anyone put faith in anything he says? I mean, looking at it rationally, not emotionally: is he the guy to trust now? If I were a potential investor I would not be inclined to put my faith in him.
I am really baffled as to why he has lasted this long.
Oh, well. What do I know? I'm just a guy who always had to perform well in my job to keep it.
