In a statement, CEO Henry Juszkiewicz said that the company "felt compelled to settle as the costs of proving our case at trial would have cost millions of dollars and taken a very long time to resolve."
The government had no evidence the wood purchased had not been harvested prior to 2006 regardless of when they bought it (the last time in 2006) and, accordingly, never had a case.
There was no raid at that time. The massive raid and totally shutting the company down didn't happen until after Gibson's contribution to Romney. The government was holding all of Gibson's wood - although never claimed to be illegal in any way. Basically, Gibson agreed to buy back the wood that was not even in question and give the Fish and Wildlife department $50,000 to get off their back. In return the government dropped the case.
