To All Officers:

I could not be more excited about our announced combination of AT&T and Time Warner.  We entered this transaction for many reasons, but those reasons all boil down to one thing – we want to get the most content to the most people at the lowest prices, delivered on any screen, particularly mobile.  We are convinced that this merger will change the game in video by bringing innovation and investment to a media industry that is begging for both and to consumers who want a better video experience.

To make this happen, we will need to be smart, nimble, and creative in how we manage our business and empower our people. To that end, below are the core, bedrock principles for how we plan to go to market as a single company after close. I have begun sharing these principles externally, so I wanted to share them with you as well. From a competitive standpoint, I consider this the "Magna Carta" of our merger.
