Those margins are misleading because they're _multi_ service operators, and accounting standards require that you can only list direct costs.
Revenue is easy: how much did you take in for video? phone? Internet access?
Costs are harder because you can only include business line direct costs. Since the cable plant is used by voice, video and data services it's not a direct cost of any of them. Same thing with the service vehicle fleet, call centers, etc. Most things get saddled in "administration" categories and obscure the true cost of providing the service. As a company overall, their margins been hovering around 8-12%.
