Item 2.05 Costs Associated with Exit or Disposal Activities

On August 29, 2016, the board of directors (the “Board”) of Trinseo S.A. (the “Company”) approved a plan to cease manufacturing operations at its latex manufacturing facility in Livorno, Italy by the 2016 year end. The closure of manufacturing operations is a result of declining demand for graphical paper and is expected to provide improved asset utilization, as well as cost reductions within the Company’s European latex business.

We expect to incur approximately $24 million of pre-tax, non-recurring charges related to the cessation of manufacturing activities at this facility, including approximately $15 million of impairment charges to write down assets to their net realizable value and cash expenditures of $9 million, which will include one-time termination benefits and other costs associated with the closure of manufacturing operations. Of these charges approximately $18 million are expected to be taken in third quarter, with the majority of the remainder intended to be taken during the fourth quarter of 2016. These charges are subject to ongoing negotiations with the local Italian labor union, industrial association, and government authorities in Italy and are subject to receiving a final valuation of the land on which this facility is located.
