The Company’s ability to continue as a going concern at June 30, 2019 was contingent upon its ability to comply with the financial and other covenants contained in the DIP Term Loan Facility, the DIP ABL Facility and its ability to successfully implement the Plan (defined in Note 2), among other factors. 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 2 for more information. Financial Reporting in Reorganization Effective on April 1, 2019, the Company applied Accounting Standard Codification, No. 852, “Reorganizations,” (“ASC No. 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 Condensed 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 Condensed 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. See Note 3 for more information. The accompanying Condensed Consolidated Balance Sheet as of December 31, 2018 included in this Quarterly Report on Form 10-Q has been prepared under the basis of accounting assuming that the Company will continue as a going concern, which contemplates continuity of operations, realization of assets and satisfaction of liabilities and commitments in the normal course of business. The Company has made certain adjustments to the Condensed Consolidated Balance Sheet as of December 31, 2018 including the reclassification of certain outstanding debt to current liabilities and the write-off of unamortized deferred financing costs related to such debt.

Background and Basis of Presentation

Based in Columbus, Ohio, Hexion Inc. (“Hexion” or the “Company”) serves global adhesive, coatings, composites and industrial markets through a broad range of thermoset technologies, specialty products and technical support for customers in a diverse range of applications and industries. The Company’s business is organized based on the products offered and the markets served. At June 30, 2019, the Company had three reportable segments: Epoxy, Phenolic and Coating Resins; Forest Products Resins; and Corporate and Other.

As a result of the Company’s reorganization and emergence from Chapter 11 (as defined below) on July 1, 2019, the Company’s direct parent is Hexion Intermediate Holding 2, Inc., 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”).

Going Concern

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 2), 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. The Company’s ability to continue as a going concern at June 30, 2019 was contingent upon its ability to comply with the financial and other covenants contained in the DIP Term Loan Facility, the DIP ABL Facility and its ability to successfully implement the Plan (defined in Note 2), among other factors. 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 2 for more information.

Financial Reporting in Reorganization

Effective on April 1, 2019, the Company applied Accounting Standard Codification, No. 852, “Reorganizations,” (“ASC No. 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 Condensed 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 Condensed 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. See Note 3 for more information.

The accompanying Condensed Consolidated Balance Sheet as of December 31, 2018 included in this Quarterly Report on Form 10-Q has been prepared under the basis of accounting assuming that the Company will continue as a going concern, which contemplates continuity of operations, realization of assets and satisfaction of liabilities and commitments in the normal course of business.
