Restructuring, Goodwill Impairment and Asset Related Charges - Net

DowDuPont Cost Synergy Program

The activities related to the DowDuPont Cost Synergy Program ("Synergy Program") are expected to result in additional cash expenditures of approximately $1,175 million to $1,315 million , primarily by the end of 2019, consisting of severance and related benefit costs and costs associated with exit and disposal activities, including environmental remediation (see Note 5 to the Consolidated Financial Statements). The Synergy Program includes certain asset actions, including strategic decisions regarding the cellulosic biofuel business reflected in the preliminary fair value measurement of DuPont’s assets as of the Merger date. Current estimated total pretax restructuring charges could be impacted by future adjustments to the preliminary fair value of DuPont’s assets. The Company expects to incur additional costs in the future related to its restructuring activities. Future costs are expected to include demolition costs related to closed facilities and restructuring plan implementation costs; these costs will be recognized as incurred. The Company also expects to incur additional employee-related costs, including involuntary termination benefits, related to its other optimization activities. These costs cannot be reasonably estimated at this time.

Restructuring Plans Initiated Prior to Merger

The activities related to Dow's 2016 restructuring plan are expected to result in additional cash expenditures of approximately $70 million, primarily through June 30, 2018, consisting of severance and related benefit costs and costs associated with exit and disposal activities, including environmental remediation (see Note 5 to the Consolidated Financial Statements).
