Background and Basis of Presentation [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	Background and Basis of Presentation Based in Columbus, Ohio, Hexion Inc. (“Hexion” or the “Company”), serves global industrial markets through a broad range of thermoset technologies, specialty products and technical support for customers in a diverse range of applications and industries. At December 31, 2019, the Company had 45 production and manufacturing facilities, with 21 located in the United States. The Company’s business is organized based on the products offered and the markets served. At December 31, 2019, the Company had three reportable segments: Forest Products Resins; Epoxy, Phenolic and Coating Resins; and Corporate and Other. As a result of the Company’s reorganization and emergence from Chapter 11 (as defined in Note 3) on the morning of July 1, 2019 (the “Effective Date”), the Company’s direct parent is Hexion Intermediate Holding 2, Inc. (“Hexion Intermediate”), a holding company and wholly owned subsidiary of Hexion Intermediate Holding 1, Inc., a holding company and wholly owned subsidiary of Hexion Holdings Corporation, the ultimate parent of Hexion (“Hexion Holdings”). Prior to its reorganization, the Company’s parent was Hexion LLC, a holding company and wholly owned subsidiary of Hexion Holdings LLC (now known as Hexion TopCo, LLC or “TopCo”), the previous ultimate parent entity of Hexion, which was controlled by investment funds managed by affiliates of Apollo Management Holdings, L.P. (together with Apollo Global Management, Inc. and its subsidiaries, “Apollo”). On the Effective Date, the Company’s existing common stock were cancelled and 100 new shares of common stock were issued at a par value of $0.01 to the Company’s new direct parent Hexion Intermediate in accordance with the Plan (as defined in Note 3). See Note 3 for more information. The Company filed for Chapter 11 bankruptcy protection on April 1, 2019 (the “Petition Date”) and as the Company previously disclosed, based on its financial condition and its projected operating results, the defaults under its debt agreements, and the risks and uncertainties surrounding its Chapter 11 proceedings (see Note 3), that there was substantial doubt as to the Company’s ability to continue as a going concern as of the issuance of the Company’s 2018 Annual Report on Form 10-K. After the Company’s emergence from Chapter 11 on July 1, 2019, based on its new capital structure, liquidity position and projected operating results, the Company expects to continue as a going concern for the next twelve months. See Note 3 for more information. Financial Reporting in Reorganization Effective on the Petition Date, the Company applied Accounting Standard Codification, No. 852, “Reorganizations,” (“ASC 852”) which is applicable to companies under Chapter 11 bankruptcy protection. It requires the financial statements for periods subsequent to the Chapter 11 filing to distinguish transactions and events that are directly associated with the reorganization from the ongoing operations of the business. Expenses, realized gains and losses, and provisions for losses that are directly associated with reorganization proceedings must be reported separately as “Reorganization items, net” in the Consolidated Statements of Operations. In addition, the balance sheet must distinguish debtor pre-petition liabilities subject to compromise (“LSTC”) from liabilities of non-filing entities, pre-petition liabilities that are not subject to compromise and post-petition liabilities in the accompanying Consolidated Balance Sheet. LSTC are pre-petition obligations that are not fully secured and have at least a possibility of not being repaid at the full claim amount. LSTC related to debt, its related interest payable and certain affiliate payables were settled in accordance with the Plan, as applicable, on or shortly after the Company emerged from Chapter 11 bankruptcy on July 1, 2019. As of July 1, 2019, all remaining liabilities subject to compromise were not impaired and remain on the Company’s Consolidated Balance Sheets. The Company’s Consolidated Balance Sheets as of December 31, 2019 and 2018 included in this Annual Report on Form 10-K were prepared under the basis of accounting assuming that the Company will continue as a going concern, which contemplated continuity of operations, realization of assets and satisfaction of liabilities and commitments in the normal course of business. Fresh Start Accounting On the Effective Date, in accordance with ASC 852, the Company applied fresh start accounting to its financial statements as (i) the holders of existing voting shares of the Company prior to its emergence received less than 50% of the voting shares of the Company outstanding following its emergence from bankruptcy and (ii) the reorganization value of the Company’s assets immediately prior to confirmation of the plan of reorganization was less than the post-petition liabilities and allowed claims. Fresh start accounting was applied to the Company’s consolidated financial statements as of July 1, 2019, the date it emerged from bankruptcy, which resulted in a new basis of accounting and the Company became a new entity for financial reporting purposes. As a result, the Company allocated the reorganization value of the Company to its individual assets based on their estimated fair values. Reorganization value represents the fair value of the Company’s assets before considering liabilities. The excess reorganization value over the fair value of identified tangible and intangible assets was reported as goodwill. As a result of the application of fresh start accounting and the effects of the implementation of the Plan, the Consolidated Financial Statements after the Effective Date are not comparable with the Consolidated Financial Statements prior to that date. References to “Successor” or “Successor Company” relate to the financial position and results of operations of the Company after the Effective Date. References to “Predecessor” or “Predecessor Company” refer to the financial position and results of operations of the Company on or before the Effective Date. Refer to Note 4 for more information.
