(Reuters) - Northrop Grumman Corp (N:NOC), maker of Global Hawk drones, said it could buy back up to an additional $4 billion worth of shares as part of a new buyback authorization.
Based on Wednesday's close of $170.96, Northrop could buy back up to roughly 12.5 percent of its outstanding shares.
The company had said in July it was on track to complete a previously announced 60 million share repurchase program by the end of the year.
