BASIS OF PRESENTATION |
Basis of Presentation | The unaudited interim condensed consolidated financial statements of Trinseo PLC and its subsidiaries (the “Company”) as of and for the periods ended June 30, 2024 and 2023 were prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and reflect all adjustments, consisting only of normal recurring adjustments, which, in the opinion of management, are considered necessary for the fair statement of the results for the periods presented. Because they cover interim periods, the statements and related notes to the financial statements do not include all disclosures normally provided in annual financial statements, and therefore, these statements should be read in conjunction with the 2023 audited consolidated financial statements included within the Company’s Annual Report on Form 10-K (“Annual Report”) filed with the Securities and Exchange Commission (“SEC”) on February 23, 2024. The Company’s condensed consolidated financial statements presented herein reflect the latest estimates and assumptions made by management that affect the reported amounts and related disclosures as of and for the period ended June 30, 2024. However, actual results could differ from these estimates and assumptions. The December 31, 2023 condensed consolidated balance sheet data presented herein was derived from the Company’s December 31, 2023 audited consolidated financial statements, but does not include all disclosures required by GAAP for annual periods. Effective January 1, 2024, the Company’s Feedstocks segment, which included the Company’s production and procurement of styrene monomer outside of North America, was eliminated as a result of the closures of the styrene plants located in Boehlen, Germany and Terneuzen, the Netherlands under an asset restructuring plan. As a result, the Company realigned its reporting segments to reflect the new model under which the business is managed with five segments, all of which remain unchanged from the Company’s prior six segment segmentation: Engineered Materials, Latex Binders, Plastics Solutions, Polystyrene, and Americas Styrenics. Therefore, certain prior year information has been adjusted to show the historical results of the Feedstocks segment within the segments that consumed styrene monomer in their end products, Latex Binders, Plastics Solutions and Polystyrene. Refer to Notes 3, 4 and 17 for further information. Throughout this Quarterly Report, unless otherwise indicated, amounts and activity are presented on a continuing operations basis.
