The day the DOJ investigation was announced, the stock dropped from a previous close of $23.11 to close at $15.38. This was in March 2008. It did not hit the $.35 level until December 2008. The stock price did hit around $31 but that was in the summer of 2007 around the time that the buyout deal was announced.
The buyout transaction was ended in January 2008, two months before the DOJ investigation became public knowledge. The $17 million fee was a standard break-up fee paid by the prospective buyer due to their inability to close the transaction.
