Thereafter, Liberty will be entitled to designate three nominees to be elected as directors and A/N will be entitled to designate two nominees to be elected as directors, in each case provided that each maintains certain specified voting or equity ownership thresholds, provided that each nominee must meet any applicable requirements or qualifications. Each of A/N and Liberty will be entitled to nominate at least one director to each of the committees of the Charter board of directors, subject to applicable stock exchange listing rules and certain specified voting or equity ownership thresholds for each of A/N and Liberty, and provided that the nominating and compensation committees will have at least a majority of directors independent from A/N, Liberty and New Charter (referred to as the “unaffiliated directors”). The nominating committee will be comprised of three unaffiliated directors, and one designee of each of A/N and Liberty. A/N and Liberty also will have certain other committee designation and other governance rights. Mr. Thomas Rutledge, the Company's Chief Executive Officer ("CEO"), will be offered the positions of CEO and chairman of New Charter. The Company is aware that Dr. John Malone, one of Charter's directors, may be deemed to have a 36.8% voting interest in Liberty Interactive Corp. (“Liberty Interactive”) and is Chairman of the board of directors, an executive officer position, of Liberty Interactive. Liberty Interactive owns 38.0% of the common stock of HSN, Inc. (“HSN”) and has the right to elect 20% of the board members of HSN. Liberty Interactive wholly owns QVC, Inc (“QVC”). The Company has programming relationships with HSN and QVC. For the three and nine months ended September 30, 2015, the Company recorded payments in aggregate of approximately $4 million and $12 million, respectively, and for the three and nine months ended September 30, 2014, the Company recorded payments in aggregate of approximately $3 million and $9 million, respectively, from HSN and QVC as part of channel carriage fees and revenue sharing arrangements for home shopping sales made to customers in the Company's footprint.
