Autonomy CEO Michael Lynch “had more than 500 million reasons to lie to HP” when he sold the U.K. company to the Silicon Valley giant in 2011, federal prosecutors said during closing arguments Monday in Lynch’s fraud case.

Assistant U.S. Attorney Robert Leach spent four hours walking the jury through a complex web of transactions constituting the 14 counts of wire fraud and one count of conspiracy with which Lynch and his former vice president of finance, Stephen Chamberlain, are charged. “There’s an old saying for our line of work: Follow the money. It’s easy in this case,” Leach said.
