Related Party Transactions	Related Party Transactions On June 30, 2011, Cablevision spun off the Company (the "Distribution") and the Company became an independent public company. At the time of the Distribution, both Cablevision and AMC Networks were controlled by Charles F.

Members of the Dolan Family, for purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended, including trusts for the benefit of the Dolan Family, collectively beneficially own all of the Company's outstanding Class B Common Stock and own approximately 3% of the Company's outstanding Class A Common Stock.
