Accounting Standards Update and Change in Accounting Principle [Abstract]
ASC Update No. 2016-13 Financial Instruments - Credit Losses (FASB ASC Topic 326, Financial Instruments - Credit Losses)	ASC Update No. 2016-13 In June 2016, the FASB issued ASC Update No. 2016-13, Financial Instruments - Credit Losses (FASB ASC Topic 326, Financial Instruments - Credit Losses). We adopted the standard as of January 1, 2020 using the modified retrospective method. Under this method, we applied the new credit loss measurement guidance to financial assets measured at amortized cost on the date of adoption and recognized the cumulative effect of initially applying the standard as an adjustment to the opening balance of retained earnings. Results for reporting periods beginning after January 1, 2020 are presented in accordance with FASB ASC Topic 326. Prior period amounts have not been restated and are reported in accordance with legacy GAAP requirements in FASB ASC Topic 310, Receivables. Upon the adoption of FASB ASC Topic 326, credit loss reserves are recorded when financial assets are established if credit losses are expected over the asset’s contractual life. These losses were previously expensed when it became probable that a loss would be incurred. As a result of the adoption of FASB ASC Topic 326, we recorded a net reduction to opening retained earnings on January 1, 2020 related to the establishment of credit loss reserves on Trade accounts receivable and recorded a corresponding increase in the Allowance for credit losses, a contra Trade accounts receivable account. The adoption had an immaterial impact on our financial position and results of operations.
ASC Update No. 2018-15 Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40)	ASC Update No. 2018-15 In August 2018, the FASB issued ASC Update No. 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. The purpose of Update No. 2018-15 is to 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 (and hosting arrangements that include an internal-use software license). Update No. 2018-15 is effective for annual periods beginning after December 15, 2019, including interim periods within those annual periods. Early adoption is permitted, including adoption in any interim period. We adopted Update No. 2018-15 in the first quarter of 2020. The adoption had an immaterial impact on our financial position and results of operations.
ASC Update No. 2018-18 Collaborative Arrangements (Topic 808): Clarifying the Interaction Between Topic 808 and Topic 606	ASC Update No. 2018-18 In November 2018, the FASB issued ASC Update No. 2018-18, Collaborative Arrangements (Topic 808): Clarifying the Interaction Between Topic 808 and Topic 606. The purpose of Update No. 2018-18 is to clarify the interaction between FASB ASC Topic 808 and FASB ASC Topic 606, Revenue from Contracts with Customers (FASB ASC Topic 606) as FASB ASC Topic 808 did not provide comprehensive recognition or measurement guidance for collaborative arrangements, and the accounting for those arrangements was often based on an analogy to other accounting literature or an accounting policy election. Update No. 2018-18 is effective for annual periods beginning after December 15, 2019. We adopted Update No. 2018-18 in the first quarter of 2020. The adoption had an immaterial impact on our financial position and results of operations.
ASC Update No. 2020-10 Codification Improvements	ASC Update No. 2020-10 In October 2020, the FASB issued ASC Update No. 2020-10, Codification Improvements.

Update No. 2020-10 is effective for annual periods beginning after December 15, 2020, for public business entities. We plan to adopt Update No. 2020-10 in the first quarter of 2021 and expect it will have an immaterial impact on our financial position and results of operations.
ASC Update No. 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40)	ASC Update No. 2020-06 In August 2020, the FASB issued ASC Update No. 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. The amendments in Update No. 2020-06 simplify the complexity associated with applying U.S. GAAP for certain financial instruments with characteristics of liabilities and equity. More specifically, the amendments focus on the guidance for convertible instruments and derivative scope exception for contracts in an entity’s own equity. Update No. 2020-06 is effective for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020, including interim periods within those fiscal years.

The purpose of Update No. 2019-12 is to continue the FASB’s Simplification Initiative to reduce complexity in accounting standards. The amendments in Update No. 2019-12 simplify the accounting for income taxes by removing certain exceptions related to the incremental approach for intraperiod tax allocation, the requirement to recognize or derecognize deferred tax liabilities related to equity method investments that are also foreign subsidiaries, and the methodology for calculating income taxes in an interim period. In addition to removing these exceptions, Update No. 2019-12 also clarifies and simplifies other aspects of the accounting for income taxes. Update No. 2019-12 is effective for annual periods beginning after December 15, 2020, including interim periods within those annual periods. We plan to adopt Update No. 2019-12 in the first quarter of 2021 and expect it will have an immaterial impact on our financial position and results of operations.
