Such shares of the AMC Networks Class A Common Stock and Class B Common Stock, collectively, represent approximately 70% of the aggregate voting power of AMC Networks’ outstanding common stock. Members of the Dolan Family are also the controlling stockholders of The Madison Square Garden Company (“MSG”) and MSG Networks Inc. (“MSG Networks”). Prior to June 21, 2016, members of the Dolan Family were also the controlling stockholders of Cablevision Systems Corporation (“Cablevision”). On June 21, 2016, Cablevision was acquired by a subsidiary of Altice N.V. and a change in control occurred which resulted in members of the Dolan Family no longer being controlling stockholders of the surviving company, Altice USA. Accordingly, Altice USA is not a related party of AMC Networks. The Company and its related parties routinely enter into transactions with each other in the ordinary course of business. Revenues, net from related parties amount to $1.5 million for the three months ended September 30, 2017 and 2016, respectively, and $4.6 million and $14.4 million for the nine months ended September 30, 2017 and 2016, respectively. Amounts charged to the Company, included in selling, general and administrative expenses, pursuant to transactions with its related parties amounted to $0.2 million and $0.6 million for the three months ended September 30, 2017 and 2016, respectively, and $1.2 million and $2.5 million for the nine months ended September 30, 2017 and 2016, respectively. On June 16, 2016, AMC Networks entered into an arrangement with the Dolan Family Office, LLC (“DFO”), MSG and MSG Networks providing for the sharing of certain expenses associated with executive office space which will be available to Charles F. Dolan (the Executive Chairman and a director of the Company and a director of MSG and MSG Networks), James L. Dolan (the Executive Chairman and a director of MSG and MSG Networks and a director of the Company), and the DFO which is controlled by Charles F. Dolan. The Company’s share of office expenses is not material.
