The cable giants said in February, when Marcus had been in the job of CEO for less than two months, that Comcast would buy its rival for $45.2 billion.
According to a regulatory filing, the "golden parachute" pay package for Marcus includes $20.5 million in cash and $56.5 million in stock and options. He's also up for a $2.5-million bonus depending on the company's performance until the closing of the deal.
Comcast's takeover of Time Warner Cable, which will allow it to provide television, telephone and Internet service to nearly 30 million homes across the country, requires approval from the Federal Communications Commission and U.S. Department of Justice.
Media watchdogs and politicians have expressed concern over letting one company have so much control.
