What you are saying is incorrect. The SEC filings prove my point.
Not every Chapter 11 results in equity being cancelled. But when a Company says it WILL be cancelled, you can bet IT WILL BE CANCELLED. And Quiksilver says the equity will be cancelled, and the stock will be worthless.
"All of the Company’s existing equity securities, including its shares of common stock and warrants, will be cancelled and extinguished, without holders receiving any distribution."
