Liberty Broadband On May 1, 2013, Liberty Media completed its purchase from investment funds managed by, or affiliated with, Apollo Global Management, LLC ("Apollo"), Oaktree Capital Management, L.P. ("Oaktree") and Crestview Partners ("Crestview") of approximately 26.9 million shares and warrants to purchase approximately 1.1 million shares in Charter for approximately $2.6 billion (the "Liberty Transaction"), which represented, at the time, a price per share of $95.50 and an approximate 27% beneficial ownership in Charter. In connection with the Liberty Transaction, Charter entered into a stockholders agreement with Liberty Media (as amended, the “Stockholders Agreement”). Pursuant to the Stockholders Agreement, at the closing of the Liberty Transaction on May 1, 2013, Charter’s board of directors appointed four designees of Liberty Media to the Charter board of directors: John C. Malone, Chairman of the Board of Liberty Media, Gregory B. Maffei, President and Chief Executive Officer of Liberty Media, Balan Nair, Executive Vice President and Chief Technology Officer of Liberty Global, Plc. and Michael P. Huseby, then the Chief Financial Officer, and currently the Chief Executive Officer, of Barnes & Noble, Inc. In connection with the distribution of all of the capital stock of Liberty Broadband Corporation (“Liberty Broadband”) to stockholders of Liberty Media in a spin off transaction that was completed in November 2014 and also in connection with the consummation of the previously announced reorganization of Charter in connection with the Transactions (the “Reorganization”), on September 29, 2014 Liberty Media, Liberty Broadband and Charter entered into an amendment to the Stockholders Agreement. Pursuant to that amendment, Liberty Media assigned all of its rights and obligations under the Stockholders Agreement to Liberty Broadband, Liberty Broadband assumed such rights and agreed to perform all such obligations and Charter consented to such assignment and assumption. As a result, Liberty Broadband was substituted for Liberty Media for all purposes under the Stockholders Agreement. Liberty Broadband also acknowledged and agreed that the four designees of Liberty Media serving on Charter’s board of directors would continue in such capacity as designees of Liberty Broadband. The amendment also provides that, effective upon the consummation of the Reorganization, Charter will assign all of its rights, liabilities and obligations under the stockholders agreement to the reorganized Charter and the reorganized Charter will assume all of Charter’s liabilities and obligations under the Stockholders agreement. Subject to Liberty Broadband’s continued ownership of 20% or more of the outstanding shares of Class A common stock of Charter, the Stockholders Agreement provides that Liberty Broadband will be entitled to designate up to four persons as nominees for election to Charter’s board of directors at least until January 2016 and that one such designee director (as specified by Liberty Broadband) will serve on each of the Audit Committee, the Nominating and Corporate Governance Committee, and the Compensation and Benefits Committee of Charter’s board of directors. Consistent with these provisions, Mr. Malone serves on the Nominating and Corporate Governance Committee, Mr. Maffei serves on the Finance Committee and the Compensation and Benefits Committee and Mr. Huseby serves on the Audit Committee. Liberty Broadband has agreed that, so long as its designees are included in the group recommended by the Nominating and Corporate Governance Committee, it will vote its shares of Class A common stock in accordance with the recommendation of the Nominating and Corporate Governance Committee of the board of directors with respect to the election or removal of directors. Charter can elect, by notice to Liberty Broadband in early January 2016, to terminate the obligation to nominate Liberty Broadband’s designees to the board and, in such event, the standstill provisions noted below will also terminate. Beginning in 2017, Liberty Broadband and Charter will each have an annual right to terminate the board nomination and standstill obligations by delivering notice to the other party of such termination in early January of such year. Subject to certain limited exceptions, Liberty Broadband agreed that it will not, directly or indirectly; acquire voting securities of Charter in excess of 35% prior to the fifth business day of January 2016 and thereafter in excess of 39.99% of the outstanding voting securities of Charter. Liberty Broadband is also subject to certain customary standstill provisions that prohibit it from, among other things, engaging in any solicitation of proxies or consents relating to the election of directors, proposing a matter for submission to a vote of shareholders of Charter or calling a meeting of shareholders of Charter or taking any action or making any public statement not approved by the board of directors to seek to control or influence the management, the board of directors or the policies of Charter. The standstill limitations described above will cease to apply to Liberty Broadband beginning in January 2016 if Charter elects to terminate its obligation to nominate Liberty Broadband’s designees for election at the 2016 annual meeting of stockholders, as described above. In addition, the standstill limitations will cease to apply once Liberty Broadband owns less than 5% of the outstanding Class A common stock and upon termination by either party in 2017 and thereafter as described above. The Company is aware that Dr. Malone may be deemed to have a 36.0% 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 37.6% 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 which pre-date the Liberty Media Transaction. For the year ended December 31, 2014 and nine months ended December 31, 2013, the Company recorded payments in aggregate of approximately $14 million and $10 million, respectively, from HSN and QVC as part of channel carriage fees and revenue sharing arrangements for home shopping sales made to customers in Charter's footprint.

The Company purchases programming from both Discovery and Starz pursuant to agreements entered into prior to the Liberty Media Transaction and Dr. Malone and Mr. Maffei joining Charter's board of directors.
