Happened to me twice. Both time I was thinking: "It's a
business, I don't think it will go to zero. And it's only $5000. I will bet it." The first time I got $84 back. The second time I got $137 back. There is no the third time.
One is Enron, the another is a big health insurance company (3 billion revenue a year, but borrowed billions to buy tens of companies to make that 3 billion revenue, dead).
