Viacom's fourth quarter recently topped Wall Street expectations with a total revenue increase of 5 percent to $3.3 billion, compared to the same period last year.
In addition, the CEO says the company is continuing to fulfill its $4 billion share buyback.
"We started to buy shares on October 1—as our new fiscal year began. We are on track to buy $400 million dollars worth of stock in this quarter. And then we will continue to buy our stock regularly as our cash flow permits while maintaining a very strong leverage ratio of 2.0 or better," Philippe Dauman, CEO of Viacom, told CNBC's "The Strategy Session" on Tuesday.
