Brian L. Roberts, chairman and chief executive officer of Comcast Corporation, said, "I look back on 2016 with pride and enthusiasm. This is a special company, with a team I am delighted to work with, executing at a high level. Were pleased to report another year of strong financial and operational results, which reflect our focus on innovation, investing in the business and putting the customer first. Our performance at Comcast Cable was exceptionally strong. We grew operating cash flow 5.6%, added 161,000 video subscribers, the best video customer results in a decade, and delivered our best high-speed Internet customer results in nine years. NBCUniversal also had a terrific year, fueled by the tremendous success of the Olympics, the opening of new attractions at our theme parks, and strong theatrical performances, particularly in animation. The consistency and strength of our results enables us to announce that we are increasing our dividend by 15% per share, we will split our stock two-for-one, the twelfth split in our companys history, and we expect to repurchase $5 billion of our stock this year. As we begin 2017, we are well positioned to continue driving growth and shareholder value as we embark on the opportunities ahead."
