 Skydance and its investors will spend more than $8 billion in a complex deal to acquire Sherry Redstone's family-run National Amusements, which holds the controlling stake in Paramount, the parent company of CBS News. The merger does allow for a 45-day go-shop period, which keeps the door open for a superior bid. However, Sherry Redstone said in an email to employees late Sunday that she expects the deal to be completed in the first half of next year, pending regulatory approval.
