Comcast and Time Warner Cable could offload between 3 million and 5 million customers to Charter Communications, according to a Financial Times report. Selling off a sizable chunk of customers could help better the odds of Comcasts TWC acquisition getting a thumbs up from federal regulators. Comcast claims those assets and subscribers would be worth a total of $17 billion, a figure that would climb if the company winds up letting go of 5 million customers. If a deal can be worked out, it would be a decent consolation prize for Charter, the fourth-largest US cable company.
