Restructuring and Related Activities [Abstract] |
RESTRUCTURING CHARGES | NOTE 5. RESTRUCTURING CHARGES As a result of weak global resin demand and higher cost structures within the European region, we began a review of our global Epoxy asset footprint to optimize the most productive and cost-effective assets to support our strategic operating model. As part of this review, we announced operational cessations in the fourth quarter of 2022 and the first half of 2023 (collectively, Epoxy Optimization Plan). On June 20, 2023, we announced we had made the decision to cease all remaining operations at our Gumi, South Korea facility, reduce epoxy resin capacity at our Freeport, TX facility, and reduce our sales and support staffing across Asia. These actions were substantially completed by December 31, 2023. On March 21, 2023, we announced we had made the decision to cease operations at our cumene facility in Terneuzen, Netherlands and solid epoxy resin production at our facilities in Gumi, South Korea and Guaruja, Brazil. The closures were completed in the first quarter 2023. During the fourth quarter of 2022, we committed to and completed a plan to close down one of our bisphenol production lines at our Stade, Germany site. For the year ended December 31, 2023 and 2022, we recorded pretax restructuring charges of $73.4 million and $8.0 million, respectively, for the write-off of equipment and facility costs, employee severance and related benefit costs, contract termination costs and facility exit costs related to these actions. We expect to incur additional restructuring charges through 2025 of approximately $25 million related to these actions. During 2021, we announced that we had made the decision to permanently close our diaphragm-grade chlor alkali capacity, representing 400,000 tons, at our McIntosh, AL facility (McIntosh Plan). The closure was completed during the third quarter of 2022. For the years ended December 31, 2023, 2022 and 2021, we recorded pretax restructuring charges of $4.7 million, $8.3 million and $5.6 million, respectively, for write-off of equipment and facility costs, lease and other contract termination costs and for facility exit costs related to this action. We expect to incur additional restructuring charges through 2027 of approximately $20 million related to these actions. Olin committed to a productivity initiative to align the organization with our strategic operating model and improve efficiencies (collectively, Productivity Plan). These actions and related activities were completed during the second quarter of 2021. For the year ended December 31, 2021, we recorded pretax restructuring charges of $10.3 million for employee severance and related benefit costs related to these actions. We do not expect to incur additional restructuring charges related to these actions. On January 18, 2021, we announced we had made the decision to permanently close our trichloroethylene and anhydrous hydrogen chloride liquefaction facilities in Freeport, TX (collectively, Freeport 2021 Plan), which were completed in the fourth quarter of 2021. For the years ended December 31, 2023, 2022 and 2021, we recorded pretax restructuring charges of $4.0 million, $2.6 million and $6.5 million, respectively, for facility exit costs related to these actions. We expect to incur additional restructuring charges through 2025 of approximately $10 million related to these actions. On December 11, 2019, we announced that we had made the decision to permanently close a chlor alkali plant with a capacity of 230,000 tons and our vinylidene chloride (VDC) production facility, both in Freeport, TX (collectively, Freeport 2019 Plan). The VDC facility and related chlor alkali plant were closed during the fourth quarter of 2020 and second quarter of 2021, respectively. For the years ended December 31, 2023, 2022 and 2021, we recorded pretax restructuring charges of $7.5 million, $6.0 million and $3.9 million, respectively, for facility exit costs related to these actions. We expect to incur additional restructuring charges through 2026 of approximately $15 million related to these actions. On March 21, 2016, we announced that we had made the decision to close a combined total of 433,000 tons of chlor alkali capacity across three separate locations (collectively, Chlor Alkali 2016 Plan). For the years ended December 31, 2022 and 2021, we recorded pretax restructuring charges of $0.4 million and $1.6 million, respectively, for the lease and other contract termination costs and facility exit costs related to these actions. We do not expect to incur additional restructuring charges related to these capacity reductions. The following table summarizes the 2023, 2022 and 2021 activities by major component of these restructuring actions and the remaining balances of accrued restructuring costs as of December 31, 2023, 2022 and 2021:
