The company, founded two decades ago, has struggled to replicate the success of its earlier "Shrek," "Kung Fu Panda" and "Madagascar" movies.

CEO Jeffrey Katzenberg has been in discussions to sell the studio, but his efforts have recently been rebuffed by several companies including Japanese telecommunications giant SoftBank Corp.,
