Viacom, CBS not in active discussions - sources

(Reuters) - Viacom Inc and CBS Corp are not in active merger discussions, although controlling shareholder Shari Redstone has had exploratory conversations with CBS directors about recombining the companies, two sources familiar with the situation told Reuters on Friday.

CBS and Viacom are both controlled by ailing Sumner Redstone, 94, and his daughter Shari, through their privately owned movie theatre company, National Amusements Inc.

Sumner Redstone split Viacom and CBS into separate companies a decade ago. He and his daughter attempted to merge the two in 2016, but the effort failed.

National Amusements, CBS and Viacom declined to comment.
