ITEM 2.05  Costs Associated with Exit or Disposal Activities.
On November 21, 2019, the Board of Directors of Trinseo S.A. (the "Company") adopted a corporate restructuring plan associated with the Company's shift to a global functional structure and business excellence initiatives to drive greater focus on business process optimization and efficiency, which plan was first disclosed to employees on November 29, 2019.  The corporate restructuring plan is expected to be substantially completed by the end of the first half of 2020.  The Company expects to incur restructuring charges in connection with this corporate restructuring plan ranging in total from approximately $25 million to $30 million.  The total charges will primarily consist of expenditures in the form of severance benefits to the affected employees ranging from approximately $20 million to $25 million; and lease cancellation, asset impairments and other costs ranging from approximately $5 million to $7 million.  The foregoing charges exclude pension related costs which cannot be reasonably estimated at this time.  The majority of these charges will be incurred in the fourth quarter of 2019, with the remaining amount to be incurred in 2020.  The Company expects the vast majority of the cash expenditures, related primarily to severance benefits to the affected employees and the lease cancellation, to be paid by the end of 2020.  However, the actual timing and costs of the corporate restructuring plan may differ from the Company's current expectations and estimates and such differences may be material.

Forward-looking statements reflect management's evaluation of information currently available and are based on the Company's current expectations and assumptions regarding the Company's business, the economy and other future conditions. Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict. Specific factors that may impact performance or other predictions of future actions have, in many but not all cases, been identified in connection with specific forward-looking statements. Factors that might cause such a difference include, but are not limited to, those discussed in the Company's Annual Report filed with the Securities and Exchange Commission on February 28, 2019 under Part I, Item IA—"Risk Factors."
As a result of these or other factors, the Company's actual results may differ materially from those contemplated by the forward-looking statements.
