Federal investigators have reportedly started cracking Cablevision System’s books in the wake of Cablevision’s accounting investigation at AMC. A report in Newsday on Thursday said the Department of Justice and the FBI opened an investigation into Cablevision after the company revealed on June 18 it found about $18 million in improperly accrued expenses and falsified invoices. The company fired 14 executives. A lengthy probe could sideline Cablevision’s efforts to sell AMC or combine it with another entity. A Cablevision spokesperson said that the appropriate government authorities were notified of the matter, and added it would be inappropriate to comment further.
