Sumner Redstone to step down from Viacom board

The 93-year old Redstone, who has not been at an annual investor meeting since 2014, will still continue to participate in meetings in a "non-voting" role, according to the filing. It was Redstone's decision to step down, according to a source familiar with the situation, because discussions were private. Redstone stepped down as executive chair of the board last February to become Chairman Emeritus, replaced by then-CEO Philippe Dauman.
