I'm mentioned the Porsche/VW financial incident briefly in October, but this is an excellent layman's explanation of what happened.
Porsche's move took three years of careful maneuvering. It was darkly brilliant, a wealth transfer ingeniously conceived like few we've ever seen. Betting the right way, Porsche roiled the financial markets and took the hedge funds for a fortune.

Update: Not so fast there, Porsche. Bloomberg says that the company may not have the money necessary to exercise those options and realize $24.3 billion in profits.
