Dear Valued Customer:

Recently, Time Warner Cable announced plans to merge with Comcast, forming an industry-leading technology and media company dedicated to delivering great customer experiences.

Above all, this merger will benefit you, our customers. Our two companies have been behind many of the innovative services that you enjoy every day—digital cable TV, high-speed Internet, DVRs, Video On Demand and WiFi in the home and on-the-go—to name just a few. The combined company will innovate faster and deploy even better products and features, including a superior video guide, faster Broadband Internet speeds and even more WiFi access points so you can access the Internet wherever you go.

We expect the merger to close around the end of 2014. In the meantime, all of us at Time Warner Cable remain committed to providing you with great TV, ultra-fast Internet, rock solid phone service and innovative home security and monitoring. And we will continue to make significant investments to improve reliability and to enhance our customer service.

We are very excited about the promise of this combination for you, our customers. We’ll keep you posted as things evolve in the coming months.

As always, thank you for choosing Time Warner Cable.

Sincerely,
