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 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. In January 2020, the Company changed its reporting segments to align around its growth platforms. At September 30, 2020, the Company had three reportable segments: Adhesives; Coatings and Composites; and Corporate and Other. The unaudited Condensed Consolidated Financial Statements include the accounts of the Company and its majority-owned subsidiaries in which minority shareholders hold no substantive participating rights. Intercompany accounts and transactions are eliminated in consolidation. In the opinion of management, all adjustments consisting of normal, recurring adjustments considered necessary for a fair statement have been included. Results for the interim periods are not necessarily indicative of results for the entire year. Year-end condensed consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America (“U.S. GAAP”). Pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”), certain information and disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. These unaudited Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and the accompanying notes included in the Company’s most recent Annual Report on Form 10-K. Sale of Phenolic Specialty Resins Business On September 27, 2020, the Company entered into a definitive agreement (the “Purchase Agreement”) for the sale of its Phenolic Specialty Resins ("PSR"), Hexamine and European-based Forest Products Resins businesses (together with PSR, the “Held for Sale Business”) to Black Diamond Capital Management, LLC and Investindustrial (the “Buyers”) for a purchase price of approximately $425. The consideration consists of $335 in cash and certain assumed liabilities with the remainder in future contingent proceeds based on the performance of the Held for Sale Business. For more information, see Note 4 “Discontinued Operations”. As of September 30, 2020, the Company reclassified the assets and liabilities of the Held for Sale Business as held for sale on the unaudited Condensed Consolidated Balance Sheets and reported the results of the operations for the three and nine months ended September 30, 2020 as “(Loss) income from discontinued operations, net of taxes” on the unaudited Condensed Consolidated Statements of Operations. Amounts for prior periods have similarly been retrospectively reclassified for all periods presented. Additionally, the Company has included $4, $11, $4 and $10 in both “Net sales” and “Cost of sales” within the Company’s continuing operations for the Successor three and nine months ended September 30, 2020, the Successor period July 2, 2019 through September 30, 2019 and the Predecessor period January 1, 2019 through July 1, 2019, respectively, which represents sales from the Company’s continuing operations to the Held for Sale Business that were previously eliminated in consolidation. These reclassifications had no impact on “Net (loss) income” in the unaudited Condensed Consolidated Statements of Operations for any of the periods presented. Emergence from Chapter 11 and Fresh Start Accounting On April 1, 2019, the Company, Hexion Holdings LLC, Hexion LLC and certain of the Company’s subsidiaries (collectively, the “Debtors”) filed voluntary petitions (the “Bankruptcy Petitions”) for reorganization under Chapter 11 (“Chapter 11”) of the U.S. Bankruptcy Code (the “Bankruptcy Code”) in the United States Bankruptcy Court for the District of Delaware, (the “Bankruptcy Court”). The Chapter 11 proceedings were jointly administered under the caption In re Hexion TopCo, LLC , No. 19-10684 (the “Chapter 11 Cases”). The Debtors continued to operate their businesses as “debtors-in-possession” under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code and orders of the Bankruptcy Court. On June 25, 2019, the Court entered an order (the “Confirmation Order”) confirming the Second Amended Joint Chapter 11 Plan of Reorganization of Hexion Holdings LLC and its Debtor Affiliates under Chapter 11 (the “Plan”). On the morning of July 1, 2019 (the "Effective Date"), in accordance with the terms of the Plan and the Confirmation Order, the Plan became effective and the Debtors emerged from bankruptcy (the “Emergence”). As a result of the Company’s reorganization and emergence from Chapter 11 bankruptcy on 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” or “Parent”). 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.

Significant Accounting Policies

Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	Summary of Significant Accounting Policies Use of Estimates —The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and also requires the disclosure of contingent assets and liabilities at the date of the financial statements. In addition, it requires management to make estimates and assumptions that affect the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. Revenue Recognition —The Company follows the principles-based five step model to recognize revenue upon the transfer of promised goods or services to customers and in an amount that reflects the consideration for which the entity expects to be entitled in exchange for those goods or services. Revenue, net of estimated allowances and returns, is recognized when the Company has completed its performance obligations under a contract and control of the product is transferred to the customer. Substantially all revenue is recognized at the time shipment is made or upon delivery as risk and title to the product transfer to the customer. Sales, value add, and other taxes that are collected concurrently with revenue-producing activities are excluded from revenue. Contract terms for certain transactions, including sales made on a consignment basis, result in the transfer of control of the finished product to the customer prior to the point at which the Company has the right to invoice for the product. In these cases, timing of revenue recognition will differ from the timing of invoicing to customers and will result in the Company recording a contract asset. A contract asset balance of $6 is recorded within “Other current assets” at both September 30, 2020 and December 31, 2019 in the unaudited Condensed Consolidated Balance Sheet. Refer to Note 12 for additional discussion of the Company’s net sales by reportable segment disaggregated by geographic region. Cash and Cash Equivalents — The Company considers all highly liquid investments that are purchased with an original maturity of three months or less to be cash equivalents. The Company’s restricted cash balance of $3 and $4 at September 30, 2020 and December 31, 2019, respectively, represents deposits to secure certain bank guarantees issued to third parties to guarantee potential obligations of the Company primarily related to the completion of tax audits and environmental liabilities. These balances will remain restricted as long as the underlying exposures exist and are included in the unaudited Condensed Consolidated Balance Sheets as a component of “Cash and cash equivalents.” Allowance for Doubtful Accounts — Under adoption of ASU 2016-13, the Company has updated its credit loss methodology to consider a broader range of reasonable and supportable information to determine its credit loss estimates. The Company utilizes a historical aging method disaggregated by portfolio segment of geographic region, and then the Company makes any necessary adjustments for current conditions and forecasts about future economic conditions for calculating its allowance for doubtful accounts. The Company evaluates each pooled receivables’ geographic region by differing regional industrial and economic conditions, overall end market conditions and groups of customers with similar risk profiles related to timing and uncertainty of future collections. If particular accounts receivable balances no longer display risk characteristics that are similar to other pooled receivables, the Company performs individual assessments of expected credit losses for those specific receivables. Receivables are charged against the allowance for doubtful accounts when it is probable that the receivable will not be collected. During the three and nine months ended September 30, 2020, the Company increased its allowance for doubtful accounts provision for expected credit losses by less than $1, to reflect current business conditions, forecasts of future economic conditions and the impacts related to the global business and market disruptions of the coronavirus disease 2019 (“COVID-19”) pandemic in accordance with ASU 2016-13 (see Note 3 for more information). The Company’s current expectations and assumptions regarding its business, the economy and other future events and conditions are based on currently available financial, economic and competitive data and current business plans as of September 30, 2020. Actual results could vary materially depending on risks and uncertainties that may affect the Company’s operations, markets, services, prices and other factors. The Company recorded an allowance for doubtful accounts of $3 at both September 30, 2020 and December 31, 2019, to reduce accounts receivable to their estimated net realizable value. Accounts receivable balances are written-off against the allowance if a final determination of uncollectibility is made. There were no write-offs or recoveries for the Successor three and nine months ended September 30, 2020. Goodwill — Goodwill is reviewed annually for impairment of value or more frequently when potential impairment triggering events are present. The Company’s annual impairment testing date is October 1. The Company continuously monitors events which could trigger an interim impairment analysis, such as changing business conditions and environmental factors, which included the impact of the COVID-19 pandemic for the three and nine months ended September 30, 2020 and the signing of the Purchase Agreement for the Held for Sale Business in September 2020. The Company determined there was no triggering event requiring an interim impairment analysis at September 30, 2020. However, the continued duration and severity of COVID-19 may result in future impairment charges as a prolonged pandemic could have an additional impact on the results of the Company’s operations. Reclassifications — Certain amounts in the unaudited Condensed Consolidated Financial Statements for prior periods have been reclassified to conform with the current presentation. These reclassifications were to record the assets and liabilities of the Held for Sale Business and the results of operations as discontinued operations. See Note 4 for more information. Subsequent Events— The Company has evaluated events and transactions subsequent to September 30, 2020 through the date of issuance of its unaudited Condensed Consolidated Financial Statements. Recently Issued Accounting Standards Newly Adopted Accounting Standards In June 2016, the FASB issued ASU 2016-13: Financial Instruments - Credit Losses (Topic 820): Measurement of Credit Losses on Financial Instruments , (“ASU 2016-13”). The amendments in this update replace the incurred loss impairment methodology in current U.S. GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. New disclosures are also required with this standard. The standard is effective for annual and interim periods beginning after December 15, 2019. This standard impacts the Company’s accounts receivables and contract assets. The Company adopted ASU 2016-13 at January 1, 2020, using a modified retrospective adoption method. Under this method of adoption, there is no impact to the comparative Consolidated Statement of Operations and the Consolidated Balance Sheets. There was an immaterial impact of adopting ASU 2016-13 on the date of adoption. In August 2018, the FASB issued ASU 2018-15: Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40) : Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract (“ASU 2018-15”). ASU 2018-15 align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The standard was effective for annual and interim periods beginning after December 15, 2019. The Company adopted ASU 2018-15 prospectively on January 1, 2020 and the adoption had an immaterial impact on its condensed consolidated financial statements. In March 2020, the FASB issued ASU 2020-04: Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU 2020-04”). ASU 2020-04 will provide optional expedients and exceptions for a limited period of time to ease the potential burden in accounting for contracts, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The amendments in this ASU are effective for all entities as of March 12, 2020 through December 31, 2022. The Company has adopted ASU 2020-04 and the initial adoption of this ASU did not have an impact on our condensed consolidated financial statements. Recently Issued Accounting Standards In December 2019, the FASB issued ASU 2019-12: Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”) . ASU 2019-12 will simplify the accounting for income taxes by removing certain exceptions to the general principles in income tax accounting and improve consistent application of and simplify GAAP for other areas of income tax accounting by clarifying and amending existing guidance. The new guidance is effective for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. The Company is currently assessing the potential impact ASU 2019-12 will have on its condensed consolidated financial statements .

Covid-19 Impacts [Abstract]
Covid-19 [Abstract]	COVID-19 Impacts In March 2020, the World Health Organization categorized COVID-19 as a global pandemic. Around the world, local governments’ responses to COVID-19 continue to evolve, which has led to stay-at-home orders, social distancing guidelines and other preventative measures that have disrupted various industries in the global economy and the markets in which our products are manufactured, distributed and sold. During this pandemic, the Company has implemented additional guidelines to further protect the health and safety of its employees as the Company continues to operate with its suppliers and customers. The Company has maintained a focus on the safety of its employees while minimizing potential disruptions caused by COVID-19. For example, the Company is following all legislatively-mandated travel directives in the various countries where it operates, and the Company has also put additional travel restrictions in place for its associates designed to reduce the risk from COVID-19. Additionally, the Company is utilizing extended work from home options to protect its office associates, while adjusting its meeting protocols and processes at its manufacturing sites. The Company’s businesses have been designated by many governments as essential businesses and the Company’s operations have continued through September 30, 2020. While the Company has continued to operate during the pandemic, it did incur adverse financial impacts to its sales and profitability results during the three and nine months ended September 30, 2020 from COVID-19, primarily related to reduced volumes associated with the pandemic. The pandemic has impacted global economic conditions and lowered demand in many of the end use markets in which the Company operates such as automotive, aerospace, industrial products, oil and gas, construction and housing. The ultimate impact that COVID-19 will have on the Company’s future financial position, operating results and cash flows involves numerous risks and uncertainties, including new information which may emerge concerning the severity and duration of COVID-19 and actions to contain the virus or treat its impact.

Discontinued Operations and Disposal Groups [Abstract]
Disposal Groups, Including Discontinued Operations, Disclosure	Discontinued Operations On September 27, 2020, the Company entered into a Purchase Agreement for the sale of PSR, Hexamine and European-based Forest Products Resins businesses (together with PSR, the “Held for Sale Business” or the “Business”) to Black Diamond Capital Management, LLC and Investindustrial (the “Buyers”) for a purchase price of approximately $425. The consideration consists of $335 in cash and certain assumed liabilities with the remainder in future contingent proceeds based on the performance of the Held for Sale Business. The final purchase price is subject to customary post-closing adjustments. The Held for Sale Business was formerly included in the Company’s Adhesives reportable segment. Assets included in the transaction are the Company’s manufacturing sites in Barry, United Kingdom; Cowie, United Kingdom; Lantaron, Spain; Botlek, Netherlands; Iserlohn, Germany; Frielendorf, Germany; Solbiate, Italy; Kitee, Finland; Louisville, Kentucky; Acme, North Carolina; and the Company's 50% ownership interest in Hexion Schekinoazot Holding B.V. (the “Russia JV”), a joint venture that manufactures forest products resins in Russia. The Held for Sale Business produces phenolic specialty resins and engineered thermoset molding compounds used in applications that require extreme heat resistance and strength, such as after-market automotive and original equipment manufacturing (“OEM”) truck brake pads, filtration, aircraft components and foundry resins. The Business is also a significant producer of formaldehyde-based resins in Europe and merchant formaldehyde and formaldehyde derivatives in the Louisville and Acme plants, respectively. Formaldehyde-based resins, also known as forest products resins, are a key adhesive and binding ingredient used in the production of a wide variety of engineered lumber products, including medium density fiberboard (“MDF”), particleboard and oriented strand board (“OSB”). These products are used in a wide range of applications in the construction, remodeling and furniture industries. Merchant formaldehyde and formaldehyde derivatives are intermediate ingredients that are used in a variety of durable and industrial products. The Business generated annual sales of approximately $600 in 2019, and was reported within the Adhesives reportable segment. The sale is subject to customary closing conditions, including European Works Council consultation, and is expected to close in the first quarter of 2021. Until the closing date, the Company has agreed to operate the Held for Sale Business in the ordinary course. The Company has agreed to provide certain transitional services to the Buyers for a limited period of time following the closing. As of September 30, 2020, the Company reclassified the assets and liabilities of the Held for Sale Business as held for sale on the unaudited Condensed Consolidated Balance Sheets and reported the results of the operations for the three and nine months ended September 30, 2020 as “Income (loss) from discontinued operations, net of tax” on the unaudited Condensed Consolidated Statements of Operations. Amounts for prior periods have similarly been retrospectively reclassified for all periods presented. The Held for Sale Business had $14 of goodwill at both September 30, 2020 and December 31, 2019 and $61 and $63 of other intangible assets at September 30, 2020 and December 31, 2019, respectively. Goodwill was allocated based on the relative fair value of the European-based Forest Products Resins businesses, included in the Held for Sale Business, which is part of the Company’s Forest Product Resins reporting unit. Other intangible assets were specifically identified based on customer relationships within the Company’s Forest Products Resins reporting unit that are associated with the Held for Sale Business. As a result of entering into the Purchase Agreement, the Company recognized a pre-tax charge of $75 within discontinued operations, representing the difference between the fair value of the Held for Sale Business, less costs to sell, and the carrying value of net assets held for sale as of September 30, 2020. Fair value represents the expected net cash proceeds, excluding any future contingent proceeds, from the sale of the Held for Sale Business. The Company has made an accounting policy election to account for the initial and subsequent measurement of the future contingent proceeds, of up to $90, as a gain contingency. Under this model, any future contingent consideration is not recognized until all future conditions are met and the Company has earned the proceeds. The contingent proceeds are based on performance targets of the Held for Sale Business over each of the next three years, as specified in the Purchase Agreement. Thus, for purposes of this impairment analysis the fair value of the future contingent proceeds was not considered in determination of the disposal group impairment. Further, the Company concluded that the impairment of the Held for Sale Business assets did not represent an impairment triggering event for the Company’s continuing operations. The following table reconciles the carrying amounts of major classes of assets and liabilities of discontinued operations to total assets and liabilities of discontinued operations that are classified as held for sale in the Company’s unaudited Condensed Consolidated Balance Sheets: September 30, 2020 December 31, 2019 Carrying amounts of major classes of assets held for sale: Accounts receivable $ 59 $ 49 Finished and in-process goods 17 21 Raw materials and supplies 17 18 Other current assets 10 11 Total current assets 103 99 Investment in unconsolidated entities 5 3 Other long-term assets 7 11 Property, plant and equipment, net 293 297 Operating lease assets 13 12 Goodwill 14 14 Other intangible assets, net 61 63 Discontinued operations impairment (75) — Total long-term assets 318 400 Total assets held for sale $ 421 $ 499 Carrying amounts of major classes of liabilities held for sale: Accounts payable $ 48 $ 52 Income taxes payable 2 — Accrued payroll 5 5 Current portion of operating lease liabilities 2 2 Other current liabilities 10 10 Total current liabilities 67 69 Long-term pension and post employment benefit obligations 30 29 Deferred income taxes 16 15 Operating lease liabilities 5 4 Other long-term liabilities 8 8 Total long-term liabilities 59 56 Total liabilities held for sale $ 126 $ 125 The following table shows the financial results of discontinued operations for the periods presented: Successor Predecessor Successor Predecessor Three Months Ended September 30, 2020 July 2, 2019 through September 30, 2019 July 1, 2019 Nine Months Ended September 30, 2020 July 2, 2019 through September 30, 2019 January 1, 2019 through July 1, 2019 Major line items constituting pretax income of discontinued operations: Net sales $ 120 $ 149 $ — $ 360 $ 149 $ 309 Cost of sales (exclusive of depreciation and amortization) 100 130 — 301 130 263 Selling, general and administrative expense 11 8 — 33 8 17 Depreciation and amortization 8 7 — 26 7 9 Asset impairments 75 — — 75 — — Business realignment costs — 1 — 1 1 1 Other operating expense (income), net — 1 — — 1 (1) Operating (loss) income (74) 2 — (76) 2 20 Reorganization items, net — — (135) — — (135) Other non-operating expense, net 1 — — 1 — — (Loss) income from discontinued operations before income tax, earnings from unconsolidated entities (75) 2 135 (77) 2 155 Income tax expense 2 1 16 3 1 21 (Loss) income from discontinued operations, net of tax $ (77) $ 1 $ 119 $ (80) $ 1 $ 134 Earnings from unconsolidated entities, net of tax 1 — — 1 — 1 Net (loss) income attributable to discontinued operations $ (76) $ 1 $ 119 $ (79) $ 1 $ 135 Equity Method Investments The Company's 50% ownership interest in the Russia JV, accounted for using the equity method of accounting, is included in the Held for Sale Business.

Related Party Transactions [Abstract]
Related Party Transactions	Related Party Transactions Transactions with Apollo As of the Company’s emergence from bankruptcy on July 1, 2019, Apollo is no longer a related party to the Company. Sales to various Apollo affiliates were $1 for the Predecessor period January 1, 2019 through July 1, 2019. There were no purchases during the Predecessor period January 1, 2019 through July 1, 2019. Management Consulting Agreement The Company was party to a Management Consulting Agreement with Apollo (the “Management Consulting Agreement”) pursuant to which the Company received certain structuring and advisory services from Apollo and its affiliates. Apollo was entitled to an annual fee equal to the greater of $3 or 2% of the Company’s Adjusted EBITDA. In conjunction with the Company’s Chapter 11 proceedings and the Support Agreement filed on April 1, 2019, Apollo agreed to waive its annual management fee for 2019. In connection with the Company’s emergence from Chapter 11, the Management Consulting Agreement was terminated pursuant to the Confirmation Order, as of the Effective Date. Transactions with MPM As of May 15, 2019, Momentive Performance Materials (“MPM”) is no longer under the common control of Apollo and no longer a related party to the Company. There were no products sold to MPM during the Predecessor period January 1, 2019 through July 1, 2019. During the Predecessor period January 1, 2019 through July 1, 2019, the Company earned less than $1 from MPM as compensation for acting as distributor of products and had purchases of $10. Shared Services Agreement The Company previously held a shared services agreement with MPM (the “Shared Services Agreement”). Under this agreement, the Company provided to MPM, and MPM provided to the Company, certain services, including, but not limited to, executive and senior management, administrative support, human resources, information technology support, accounting, finance, legal and procurement services. On March 14, 2019, MPM terminated the Shared Services Agreement, which triggered a transition period for the parties to work together to facilitate an orderly transition of services. The transition of services was completed on September 1, 2020. During the Predecessor period January 1, 2019 through July 1, 2019 the Company incurred approximately $15 of net costs for shared services and MPM incurred approximately $14 of net costs for shared services. Included in the net costs incurred during the Predecessor period January 1, 2019 through July 1, 2019 were net billings from Hexion to MPM of $11. Other Transactions and Arrangements In March 2020, the Company entered into a $10 short term affiliate loan with its Parent at a 0% interest rate to fund Parent share repurchases. In June 2020, the Company made a $10 non-cash distribution to its Parent treated as a return of capital to settle this affiliate loan. This return of capital reduced “Paid-in capital” in the unaudited Condensed Consolidated Balance Sheet at September 30, 2020. The Company sells products and provides services to, and purchases products from, its joint ventures which are recorded under the equity method of accounting. Refer to the below table for a summary of the sales and purchases with the Company and its joint ventures which are recorded under the equity method of accounting: Successor Successor Predecessor Three Months Ended July 2, 2019 through September 30, 2019 Nine Months Ended September 30, 2020 July 2, 2019 through September 30, 2019 January 1, 2019 through July 1, 2019 Sales to joint ventures (1)(2) $ 1 $ — $ 2 $ — $ 2 Purchases from joint ventures (1) <1 1 1 1 2 (1) There were no sales to joint ventures or purchases from joint ventures for the Predecessor period July 1, 2019. (2) Sales to joint ventures is primarily comprised of sales to the Russia JV included in the Held for Sale Business. Sales to the Company’s other joint ventures were less than $1 in all Successor and Predecessor periods presented. September 30, 2020 December 31, 2019 Accounts receivable from joint ventures (1) $ 1 $ 1 Accounts payable to joint ventures — <1 (1) Accounts receivable from joint ventures is mostly comprised of receivables from the Russia JV included in the Held for Sale Business. Accounts receivable from the Company’s other joint ventures was less than $1 for both September 30, 2020 and December 31, 2019. In addition to the accounts receivable from joint ventures disclosed above, the Company had a loan receivable of $5 and $7 as of September 30, 2020 and December 31, 2019, respectively, from the Russia JV. These loan receivables have been included in “Long-term assets held for sale” within the unaudited Condensed Consolidated Balance Sheets.

Fair Value

Fair Value Disclosures [Abstract]
Fair Value Disclosures [Text Block]	Fair Value Fair value is the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Fair value measurement provisions establish a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. This guidance describes three levels of inputs that may be used to measure fair value: • Level 1: Inputs are quoted prices (unadjusted) for identical assets or liabilities in active markets. • Level 2: Pricing inputs are other than quoted prices in active markets included in Level 1, which are either directly or indirectly observable as of the reported date. • Level 3: Unobservable inputs that are supported by little or no market activity and are developed based on the best information available in the circumstances. For example, inputs derived through extrapolation or interpolation that cannot be corroborated by observable market data. Derivative Financial Instruments The Company is exposed to certain risks related to its ongoing business operations. The primary risks managed by using derivative instruments are interest rate risk, foreign currency exchange risk and commodity price risk. The Company does not hold or issue derivative financial instruments for trading purposes. Recurring Fair Value Measurements As of September 30, 2020, the Company had derivative assets related to foreign exchange, electricity and natural gas contracts of $1, which were measured using Level 2 inputs, and consisted of derivative instruments transacted primarily in over-the-counter markets. There were no transfers between Level 1, Level 2 or Level 3 measurements during the Successor nine months ended September 30, 2020, or the Successor period July 2, 2019 through September 30, 2019, and the Predecessor period from January 1, 2019 through July 1, 2019. The Company calculates the fair value of its Level 2 derivative liabilities using standard pricing models with market-based inputs, adjusted for nonperformance risk. When its financial instruments are in a liability position, the Company evaluates its credit risk as a component of fair value. At both September 30, 2020 and December 31, 2019, no adjustment was made by the Company to reduce its derivative position for nonperformance risk. When its financial instruments are in an asset position, the Company is exposed to credit loss in the event of nonperformance by other parties to these contracts and evaluates their credit risk as a component of fair value. Interest Rate Swap Th e Company will from time to time use interest rate swaps to alter interest rate exposures between floating and fixed rates on certain long-term debt. Under interest rate swaps, the Company agrees with other parties to exchange, at specified intervals, the difference between fixed rate and floating rate interest amounts calculated using an agreed-upon notional principal amount. The counter-parties to the interest rate swap agreements are financial institutions with investment grade ratings. In October 2019, the Company executed an interest rate swap syndication agreement where by Hexion receives a variable 3-month LIBOR, and pays fixed interest rate swaps, beginning January 1, 2020 through January 1, 2025 (the “Hedge”) for a total notional amount of $300. The purpose of this arrangement is to hedge the variability caused by quarterly changes in cash flow due to associated changes in LIBOR for $300 of the Company’s variable rate Senior Secured Term Loan denominated in USD ($716 outstanding at September 30, 2020). The Company has evaluated this transaction and designated this derivative instrument as a cash flow hedge under Accounting Standard Codification, No. 815, “Derivatives and hedging,” (“ASC 815”). For the Hedge, the Company records changes in the fair value of the derivative in other comprehensive income (“OCI”) and will subsequently reclassify gains and losses from these changes in fair value from OCI to the unaudited Condensed Consolidated Statement of Operations in the same period that the hedged transaction affects net (loss) income and in the same unaudited Condensed Consolidated Statement of Operations category as the hedged item, “Interest expense, net”. The following tables summarize the Company’s derivative financial instrument designated as a hedging instrument: September 30, 2020 December 31, 2019 Balance Sheet Location Notional Amount Fair Value Liability Notional Amount Fair Value Asset Derivatives designated as hedging instruments Interest Rate Swap Other current (liabilities)/assets $ 300 $ (16) $ 300 $ 3 Total derivatives designated as hedging instruments $ (16) $ 3 Amount of Loss Recognized in OCI on Derivatives Successor Predecessor Successor Predecessor Derivatives designated as hedging instruments Three Months Ended September 30, 2020 July 2, 2019 through September 30, 2019 July 1, 2019 Nine Months Ended September 30, 2020 July 2, 2019 through September 30, 2019 January 1, 2019 through July 1, 2019 Interest Rate Swaps Interest Rate Swap $ (1) $ — $ — $ (19) $ — $ — Total $ (1) $ — $ — $ (19) $ — $ — In both the Successor three and nine months ended September 30, 2020, the Company reclassified a loss of $1, respectively, from OCI to “Interest expense, net” on the Condensed Consolidated Statement of Operations related to the settlement of a portion of the Hedge. Interest Rate Cap In 2019, the Company executed an interest rate cap derivative instrument for a premium amount of less than $1. This instrument is a derivative under ASC 815 that does not qualify for hedge accounting and as a result, changes in fair value are recognized within earnings throughout the term of the instrument. For the Successor three and nine months ended September 30, 2020, the Company recognized an unrealized loss of less than $1 for the change in fair value of the instrument, which is included in “Other operating expense, net” in the unaudited Condensed Consolidated Statement of Operations. Non-derivative Financial Instruments The following table summarizes the carrying amount and fair value of the Company’s non-derivative financial instruments: Carrying Amount Fair Value Level 1 Level 2 Level 3 Total September 30, 2020 Debt $ 1,833 $ — $ 1,791 $ 54 $ 1,845 December 31, 2019 Debt $ 1,785 $ — $ 1,751 $ 64 $ 1,815 Fair values of debt classified as Level 2 are determined based on other similar financial instruments, or based upon interest rates that are currently available to the Company for the issuance of debt with similar terms and maturities. Level 3 amounts represent finance leases and sale leaseback financing arrangements whose fair value is determined through the use of present value and specific contract terms. The carrying amount and fair value of the Company’s debt is exclusive of unamortized deferred financing fees. The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable and other accrued liabilities are classified as Level 1 and are considered reasonable estimates of their fair values due to the short-term maturity of these financial instruments.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Environmental Matters The Company’s operations involve the use, handling, processing, storage, transportation and disposal of hazardous materials. The Company is subject to extensive environmental regulation at the federal, state and local levels as well as foreign laws and regulations, and is therefore exposed to the risk of claims for environmental remediation or restoration. In addition, violations of environmental laws or permits may result in restrictions being imposed on operating activities, substantial fines, penalties, damages or other costs, any of which could have a material adverse effect on the Company’s business, financial condition, results of operations or cash flows. The following table summarizes all probable environmental remediation, indemnification and restoration liabilities, including related legal expenses, at September 30, 2020 and December 31, 2019: Liability Range of Reasonably Possible Costs at September 30, 2020 Site Description September 30, 2020 (1) December 31, 2019 (1) Low High Geismar, LA $ 12 $ 12 $ 9 $ 22 Superfund and offsite landfills – allocated share: Less than 1% 3 3 2 6 Equal to or greater than 1% 6 6 5 14 Currently-owned 9 8 4 14 Formerly-owned: Remediation 19 21 16 37 Monitoring only — 1 — 1 Total $ 49 $ 51 $ 36 $ 94 (1) The table includes approximately $2 of environmental remediation liabilities related to the Held for Sale Business at both September 30, 2020 and December 31, 2019. These associated liabilities have been included in “Long-term liabilities associated with assets held for sale” within the unaudited Condensed Consolidated Balance Sheets. These amounts include estimates for unasserted claims that the Company believes are probable of loss and reasonably estimable. The estimate of the range of reasonably possible costs is less certain than the estimates upon which the liabilities are based. To establish the upper end of a range, assumptions less favorable to the Company among the range of reasonably possible outcomes were used. As with any estimate, if facts or circumstances change, the final outcome could differ materially from these estimates. At September 30, 2020 and December 31, 2019, $15 and $18 of these liabilities have been included in “Other current liabilities” with the remaining amount included in “Other long-term liabilities” within the unaudited Condensed Consolidated Balance Sheets. Following is a discussion of the Company’s environmental liabilities and the related assumptions at September 30, 2020: Geismar, LA Site —The Company formerly owned a basic chemicals and polyvinyl chloride business that was taken public as Borden Chemicals and Plastics Operating Limited Partnership (“BCPOLP”) in 1987. The Company retained a 1% interest, the general partner interest and the liability for certain environmental matters after BCPOLP’s formation. Under a Settlement Agreement approved by the United States Bankruptcy Court for the District of Delaware among the Company, BCPOLP, the United States Environmental Protection Agency and the Louisiana Department of Environmental Quality, the Company agreed to perform certain tasks related to BCPOLP’s obligations for soil and groundwater contamination at BCPOLP’s Geismar, Louisiana site. The Company bears the sole responsibility for these obligations because there are no other potentially responsible parties (“PRP”) or third parties from whom the Company could seek reimbursement. A groundwater pump and treat system to remove contaminants is operational, and natural attenuation studies are proceeding. If closure procedures and remediation systems prove to be inadequate, or if additional contamination is discovered, costs that would approach the higher end of the range of possible outcomes could result. Due to the long-term nature of the project, the reliability of timing and the ability to estimate remediation payments, a portion of this liability was recorded at its net present value, assuming a 3% discount rate and a time period of 20 years. The range of possible outcomes is discounted in a similar manner. The undiscounted liability, which is expected to be paid over the next 20 years, is approximately $16. Over the next five years, the Company expects to make ratable payments totaling $6. Superfund Sites and Offsite Landfills —The Company is currently involved in environmental remediation activities at a number of sites for which it has been notified that it is, or may be, a PRP under the United States Comprehensive Environmental Response, Compensation and Liability Act or similar state “superfund” laws. The Company anticipates approximately 50% of the estimated liability for these sites will be paid within the next five years, with the remainder over the next twenty-five years. The Company generally does not bear a significant level of responsibility for these sites, and as a result, has little control over the costs and timing of cash flows. The Company’s ultimate liability will depend on many factors including its share of waste volume, the financial viability of other PRPs, the remediation methods and technology used, the amount of time necessary to accomplish remediation and the availability of insurance coverage. The range of possible outcomes takes into account the maturity of each project, resulting in a more narrow range as the project progresses. To estimate both its current reserves for environmental remediation at these sites and the possible range of additional costs, the Company has not assumed that it will bear the entire cost of remediation of every site to the exclusion of other known PRPs who may be jointly and severally liable. The Company has limited information to assess the viability of other PRPs and their probable contribution on a per site basis. The Company’s insurance provides very limited, if any, coverage for these environmental matters. Sites Under Current Ownership —The Company is conducting environmental remediation at a number of locations that it currently owns, of which ten sites are no longer in operation. As the Company is performing a portion of the remediation on a voluntary basis, it has some control over the costs to be incurred and the timing of cash flows. The factors influencing the ultimate outcome include the methods of remediation elected, the conclusions and assessment of site studies remaining to be completed, and the time period required to complete the work. No other parties are responsible for remediation at these sites. Formerly-Owned Sites —The Company is conducting, or has been identified as a PRP in connection with, environmental remediation at a number of locations that it formerly owned and/or operated. Remediation costs at these former sites, such as those associated with the Company’s former phosphate mining and processing operations, could be material. The Company has accrued those costs for formerly-owned sites which are currently probable and reasonably estimable. One such site is the Coronet Industries, Inc. Superfund Alternative Site in Plant City, Florida. The current owner of the site alleged that it incurred environmental costs at the site for which it has a contribution claim against the Company, and that additional future costs are likely to be incurred. The Company signed a settlement agreement in 2016 with the current site owner and a past site owner, pursuant to which the Company paid $10 for past remediation costs and accepted a 40% allocable share of specified future remediation costs at this site. The Company estimates its allocable share of future remediation costs to be approximately $9. The final costs to the Company will depend on natural variations in remediation costs, including unforeseen circumstances, agency requests, new contaminants of concern and the ongoing financial viability of the other PRPs. Monitoring Only Sites —The Company is responsible for a number of sites that require monitoring where no additional remediation is expected. The Company has established reserves for costs related to these sites. Payment of these liabilities is anticipated to occur over the next ten or more years. The ultimate cost to the Company will be influenced by fluctuations in projected monitoring periods or by findings that are different than anticipated. Indemnifications —In connection with the acquisition of certain of the Company’s operating businesses, the Company has been indemnified by the sellers against certain liabilities of the acquired businesses, including liabilities relating to both known and unknown environmental contamination arising prior to the date of the purchase. The indemnifications may be subject to certain exceptions and limitations, deductibles and indemnity caps. While it is reasonably possible that some costs could be incurred, except for those sites identified above, the Company has inadequate information to allow it to estimate a potential range of liability, if any. Non-Environmental Legal Matters The Company’s continuing operations is involved in various legal proceedings in the ordinary course of business and had reserves of $1 and $1 at September 30, 2020 and December 31, 2019, respectively, for all non-environmental legal defense costs incurred and settlement costs that it believes are probable and estimable. At September 30, 2020 and December 31, 2019, $1 and $1, respectively, has been included in “Other current liabilities” in the unaudited Condensed Consolidated Balance Sheets, with the remaining amount included in “Other long-term liabilities.” Other Legal Matters —The Company is also involved in various product liability, commercial and employment litigation, personal injury, property damage and other legal proceedings, including actions that allege harm caused by products the Company has allegedly made or used, containing silica, vinyl chloride monomer and asbestos. The Company believes it has adequate reserves and that it is not reasonably possible that a loss exceeding amounts already reserved would be material. Furthermore, the Company has insurance to cover claims of these types. Other Commitments and Contingencies The Company has contractual agreements with third parties to purchase feedstocks, tolling arrangements or other services. The terms of these different agreements can vary and may be extended at the Company’s request and are cancellable by either party as provided for in each agreement. While the agreements vary by scope and terms, early cancellation of contractual agreements could result in one-time contract termination costs.

Share-based Compensation Arrangement by Share-based Payment Award [Line Items]
Shareholders' Equity and Share-based Payments [Text Block]	Stock Based Compensation The Company grants stock-based compensation to employees, directors, and other key service providers under the Hexion Holdings Corporation 2019 Omnibus Incentive Plan (the “2019 Incentive Plan”). Under the 2019 Incentive Plan, the Company may grant stock options, restricted stock units, performance stock units and other equity-based awards to be awarded from time to time as the Board of Directors of Hexion Holdings (the “Board”) determines. The restricted and performance stock units are deemed to be equivalent to one share of common stock of Hexion Holdings. The awards contain restrictions on transferability and other typical terms and conditions. In the first quarter of 2020, Hexion Holdings granted 821,758 Restricted Stock Units (“RSUs”) to certain employees and non-employee directors that time vest over three years with a weighted average grant date fair value of $15.80 per share. Additionally, Hexion Holdings granted 823,619 Performance Stock Units (“PSUs”) to certain employees that vest based on performance conditions with a weighted average grant date fair value of $15.80. Compensation cost will be recognized over the service period of the PSUs once the satisfaction of the applicable performance condition is deemed probable. As of September 30, 2020, the Company’s performance conditions underlying the PSU's were not considered probable of occurring and thus no PSU expense has been recorded. The Company recognized $4 and $13 of stock-based compensation costs for the Successor three and nine months ended September 30, 2020, respectively and $5 for the Successor period July 2, 2019 through September 30, 2019. There were no stock-based compensation cost recognized during the Predecessor period January 1, 2019 through July 1, 2019. The amounts are included in “Selling, general and administrative expense” in the Condensed Consolidated Statements of Operations. The Company’s Parent had 57,756,630 shares of common stock outstanding as of September 30, 2020.

Segment Reporting [Abstract]
Segment Information	Segment Information Realignment of Reportable Segments in 2020 As part of the Company’s continuing efforts to drive growth and greater operating efficiencies, in January 2020, the Company changed its reporting segments to align around its two growth platforms: (i) Adhesives and (ii) Coatings and Composites. At September 30, 2020, the Company’s continuing operations has three reportable segments, which consist of the following businesses: • Adhesives : these businesses focus on the global adhesives market. They include the Company’s global wood adhesives business, which now also includes the oilfield technologies group, including: forest products resin assets in North America, Latin America, Australia and New Zealand; and global formaldehyde. • Coatings and Composites : these businesses focus on the global coatings and composites market. They include the Company’s base and specialty epoxy resins and Versatic™ Acids and Derivatives businesses. • Corporate and Other : primarily corporate general and administrative expenses that are not allocated to the other segments, such as shared service and administrative functions and foreign exchange gains and losses. The Company has recast its Net Sales and Segment EBITDA (as defined below) for the Successor period July 2, 2019 through September 30, 2019 and for the Predecessor periods July 1, 2019 and January 1, 2019 through July 1, 2019 to reflect the new reportable segments. Reportable Segments Following are net sales and Segment EBITDA for continuing operations by reportable segment. Segment EBITDA is defined as EBITDA (earnings before interest, income taxes, depreciation and amortization) adjusted for certain non-cash items and other income and expenses. Segment EBITDA is the primary performance measure used by the Company’s senior management, the chief operating decision-maker and the Board of Directors to evaluate operating results and allocate capital resources among segments. Segment EBITDA is also the profitability measure used to set management and executive incentive compensation goals. Corporate and Other is primarily corporate general and administrative expenses that are not allocated to the other segments, such as shared service and administrative functions and foreign exchange gains and losses not allocated to continuing segments. Net Sales (1) : Following is continuing operations revenue by reportable segment. Product sales within each reportable segment share economically similar risks. These risks include general economic and industrial conditions, competitive pricing pressures and the Company’s ability to pass on fluctuations in raw material prices to its customers. A substantial number of the Company’s raw material inputs are petroleum-based and their prices fluctuate with the price of oil. Due to differing regional industrial and economic conditions, the geographic distribution of revenue may impact the amount, timing and uncertainty of revenue and cash flows from contracts with customers. Following is net sales by reportable segment disaggregated by geographic region: Successor Predecessor Three Months Ended September 30, 2020 July 2, 2019 through September 30, 2019 7/1/2019 Adhesives Coatings and Composites Total Adhesives Coatings and Composites Total Adhesives Coatings and Composites Total North America $ 221 $ 122 $ 343 $ 269 $ 138 $ 407 $ — $ — $ — Europe 5 132 137 6 124 130 — — — Asia Pacific 34 87 121 39 70 109 — — — Latin America 33 — 33 47 — 47 — — — Total $ 293 $ 341 $ 634 $ 361 $ 332 $ 693 $ — $ — $ — Successor Predecessor Nine Months Ended September 30, 2020 July 2, 2019 through September 30, 2019 January 1, 2019 through July 1, 2019 Adhesives Coatings and Composites Total Adhesives Coatings and Composites Total Adhesives Coatings and Composites Total North America $ 670 $ 379 $ 1,049 $ 269 $ 138 $ 407 $ 562 $ 286 $ 848 Europe 14 393 407 6 124 130 15 305 320 Asia Pacific 96 209 305 39 70 109 81 129 210 Latin America 94 — 94 47 — 47 103 — 103 Total $ 874 $ 981 $ 1,855 $ 361 $ 332 $ 693 $ 761 $ 720 $ 1,481 (1) Intersegment sales are not significant and, as such, are eliminated within the selling segment.

Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	Income Taxes The income tax expense (benefit) for the Successor three months ended September 30, 2020, July 2, 2019 through September 30, 2019, and for the Predecessor period July 1, 2019 was $17, $(5) and $191 respectively. The income tax expense (benefit) for the Successor nine months ended September 30, 2020, July 2, 2019 through September 30, 2019, and for the Predecessor period January 1, 2019 through July 1, 2019 was $8, $(5), $201 respectively. The income tax (benefit) expense is comprised of tax expense on income and tax benefit on losses from certain foreign operations. In 2020 and 2019, losses in the United States and certain foreign jurisdictions had no impact on income tax expense as no tax benefit was recognized due to the maintenance of a full valuation allowance. The effective tax rate for the Successor three months ended September 30, 2020, July 2, 2019 through September 30, 2019, and for the Predecessor period July 1, 2019 was (189)%, 10% and 6%, respectively. The effective tax rate for the Successor nine months ended September 30, 2020, July 2, 2019 through September 30, 2019, and for the Predecessor period January 1, 2019 through July 1, 2019 was (7)%, 10% and 7%, respectively. The change in the effective tax rate was primarily attributable to the amount and distribution of income and losses among the various jurisdictions in which the Company operates. The effective tax rates were also impacted by operating gains and losses generated in jurisdictions where no tax expense or benefit was recognized due to the maintenance of a full valuation allowance.

Significant Accounting Polici_2

Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2020
Accounting Policies [Abstract]
Use of Estimates, Policy [Policy Text Block]	Use of Estimates—The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and also requires the disclosure of contingent assets and liabilities at the date of the financial statements. In addition, it requires management to make estimates and assumptions that affect the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates.
Revenue [Policy Text Block]	Revenue Recognition —The Company follows the principles-based five step model to recognize revenue upon the transfer of promised goods or services to customers and in an amount that reflects the consideration for which the entity expects to be entitled in exchange for those goods or services. Revenue, net of estimated allowances and returns, is recognized when the Company has completed its performance obligations under a contract and control of the product is transferred to the customer. Substantially all revenue is recognized at the time shipment is made or upon delivery as risk and title to the product transfer to the customer. Sales, value add, and other taxes that are collected concurrently with revenue-producing activities are excluded from revenue. Contract terms for certain transactions, including sales made on a consignment basis, result in the transfer of control of the finished product to the customer prior to the point at which the Company has the right to invoice for the product. In these cases, timing of revenue recognition will differ from the timing of invoicing to customers and will result in the Company recording a contract asset. A contract asset balance of $6 is recorded within “Other current assets” at both September 30, 2020 and December 31, 2019 in the unaudited Condensed Consolidated Balance Sheet. Refer to Note 12 for additional discussion of the Company’s net sales by reportable segment disaggregated by geographic region.
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash and Cash Equivalents — The Company considers all highly liquid investments that are purchased with an original maturity of three months or less to be cash equivalents. The Company’s restricted cash balance of $3 and $4 at September 30, 2020 and December 31, 2019, respectively, represents deposits to secure certain bank guarantees issued to third parties to guarantee potential obligations of the Company primarily related to the completion of tax audits and environmental liabilities. These balances will remain restricted as long as the underlying exposures exist and are included in the unaudited Condensed Consolidated Balance Sheets as a component of “Cash and cash equivalents.”
Receivables, Trade and Other Accounts Receivable, Allowance for Doubtful Accounts, Policy [Policy Text Block]	Allowance for Doubtful Accounts — Under adoption of ASU 2016-13, the Company has updated its credit loss methodology to consider a broader range of reasonable and supportable information to determine its credit loss estimates. The Company utilizes a historical aging method disaggregated by portfolio segment of geographic region, and then the Company makes any necessary adjustments for current conditions and forecasts about future economic conditions for calculating its allowance for doubtful accounts. The Company evaluates each pooled receivables’ geographic region by differing regional industrial and economic conditions, overall end market conditions and groups of customers with similar risk profiles related to timing and uncertainty of future collections. If particular accounts receivable balances no longer display risk characteristics that are similar to other pooled receivables, the Company performs individual assessments of expected credit losses for those specific receivables. Receivables are charged against the allowance for doubtful accounts when it is probable that the receivable will not be collected. During the three and nine months ended September 30, 2020, the Company increased its allowance for doubtful accounts provision for expected credit losses by less than $1, to reflect current business conditions, forecasts of future economic conditions and the impacts related to the global business and market disruptions of the coronavirus disease 2019 (“COVID-19”) pandemic in accordance with ASU 2016-13 (see Note 3 for more information). The Company’s current expectations and assumptions regarding its business, the economy and other future events and conditions are based on currently available financial, economic and competitive data and current business plans as of September 30, 2020. Actual results could vary materially depending on risks and uncertainties that may affect the Company’s operations, markets, services, prices and other factors. The Company recorded an allowance for doubtful accounts of $3 at both September 30, 2020 and December 31, 2019, to reduce accounts receivable to their estimated net realizable value. Accounts receivable balances are written-off against the allowance if a final determination of uncollectibility is made. There were no write-offs or recoveries for the Successor three and nine months ended September 30, 2020.
Goodwill and Intangible Assets, Goodwill, Policy	Goodwill — Goodwill is reviewed annually for impairment of value or more frequently when potential impairment triggering events are present. The Company’s annual impairment testing date is October 1. The Company continuously monitors events which could trigger an interim impairment analysis, such as changing business conditions and environmental factors, which included the impact of the COVID-19 pandemic for the three and nine months ended September 30, 2020 and the signing of the Purchase Agreement for the Held for Sale Business in September 2020. The Company determined there was no triggering event requiring an interim impairment analysis at September 30, 2020. However, the continued duration and severity of COVID-19 may result in future impairment charges as a prolonged pandemic could have an additional impact on the results of the Company’s operations. Reclassifications — Certain amounts in the unaudited Condensed Consolidated Financial Statements for prior periods have been reclassified to conform with the current presentation. These reclassifications were to record the assets and liabilities of the Held for Sale Business and the results of operations as discontinued operations. See Note 4 for more information.
Subsequent Events, Policy [Policy Text Block]	Subsequent Events— The Company has evaluated events and transactions subsequent to September 30, 2020 through the date of issuance of its unaudited Condensed Consolidated Financial Statements.
New Accounting Pronouncements and Changes in Accounting Principles [Text Block]	Recently Issued Accounting Standards Newly Adopted Accounting Standards In June 2016, the FASB issued ASU 2016-13: Financial Instruments - Credit Losses (Topic 820): Measurement of Credit Losses on Financial Instruments , (“ASU 2016-13”). The amendments in this update replace the incurred loss impairment methodology in current U.S. GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. New disclosures are also required with this standard. The standard is effective for annual and interim periods beginning after December 15, 2019. This standard impacts the Company’s accounts receivables and contract assets. The Company adopted ASU 2016-13 at January 1, 2020, using a modified retrospective adoption method. Under this method of adoption, there is no impact to the comparative Consolidated Statement of Operations and the Consolidated Balance Sheets. There was an immaterial impact of adopting ASU 2016-13 on the date of adoption. In August 2018, the FASB issued ASU 2018-15: Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40) : Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract (“ASU 2018-15”). ASU 2018-15 align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The standard was effective for annual and interim periods beginning after December 15, 2019. The Company adopted ASU 2018-15 prospectively on January 1, 2020 and the adoption had an immaterial impact on its condensed consolidated financial statements. In March 2020, the FASB issued ASU 2020-04: Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU 2020-04”). ASU 2020-04 will provide optional expedients and exceptions for a limited period of time to ease the potential burden in accounting for contracts, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The amendments in this ASU are effective for all entities as of March 12, 2020 through December 31, 2022. The Company has adopted ASU 2020-04 and the initial adoption of this ASU did not have an impact on our condensed consolidated financial statements. Recently Issued Accounting Standards In December 2019, the FASB issued ASU 2019-12: Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”) . ASU 2019-12 will simplify the accounting for income taxes by removing certain exceptions to the general principles in income tax accounting and improve consistent application of and simplify GAAP for other areas of income tax accounting by clarifying and amending existing guidance. The new guidance is effective for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. The Company is currently assessing the potential impact ASU 2019-12 will have on its condensed consolidated financial statements . In August 2018, the FASB issued ASU 2018-14: Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20): Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans (“ASU 2018-14”). ASU 2018-14 modifies the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. The standard is effective for fiscal years ending after December 15, 2020. The Company is currently assessing the potential impact of ASU 2018-14 on its financial statements.
