Skilling was CEO of notorious energy firm Enron Corporation. Authorities charged him with insider trading (among other issues) because he sold his shares in the company despite knowing that it was in far different shape than the public was led to believe. Although Skilling got indicted on 10 insider trading counts, he was found convicted of only one in 2006. He was also found guilty of securities fraud and conspiracy and sentenced to 24 years in prison.
