2013–present In January 2013, IGT filed its preliminary proxy materials and indicated that it had received a Notice of Intent to Nominate four director candidates for election to the IGT Board at the Company's 2013 Annual Meeting through The Ader Group, run by Jason Ader. The intent of the notice was to inform IGT and its shareholders of a proxy battle that was going to take place, and that the Ader group's nominees include the slot-machine maker's former chief executive Charles Mathewson, and Jason Ader himself.

Following the initial release by IGT, The Ader Group issued a statement claiming that IGT relayed inaccurate information concerning Jason Ader and the Ader Group's proxy fight. The initial filing with the Securities and Exchange Commission by IGT suggested that Ader's group seeks election to the board, as Ader and Mathewson control 3 percent of IGT, (8.05 million shares), and they are seeking additional proxies for the company's 2013 annual shareholder meeting to put Mathewson back on the board IGT. IGT maintained its original statement.
