These actions are expected to be substantially completed by June 30, 2018.

As a result of these actions, the Company recorded pretax restructuring charges of $449 million in the second quarter of 2016 consisting of severance charges of $268 million, asset write-downs and write-offs of $153 million and costs associated with exit and disposal activities of $28 million.
