Accounting Standards Update and Change in Accounting Principle [Abstract]
New Accounting Pronouncements, Policy	Recently Adopted and New Accounting Standards RECENTLY ADOPTED In August 2018, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40). This ASU requires capitalization of certain implementation costs incurred in a cloud computing arrangement that is a service contract. This ASU was adopted as of January 1, 2020 and did not have a material impact on our consolidated financial statements. In August 2018, the FASB issued ASU 2018-14, Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20), which modifies the disclosure requirements for defined benefit and other postretirement plans. This ASU eliminates certain disclosures associated with accumulated other comprehensive income, plan assets, related parties and the effects of interest rate basis point changes on assumed health care costs, with other disclosures being added to address significant gains and losses related to changes in benefit obligations. This ASU also clarifies disclosure requirements for projected benefit and accumulated benefit obligations. This ASU was adopted as of January 1, 2020 and did not have a material impact on our consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments (Topic 326), which modifies the measurement approach for credit losses on financial assets measured on an amortized cost basis from an 'incurred loss' method to an 'expected loss' method. Such modification of the measurement approach for credit losses eliminates the requirement that a credit loss be considered probable, or incurred, to impact the valuation of a financial asset measured on an amortized cost basis. The amended guidance requires the measurement of expected credit losses to be based on relevant information, including historical experience, current conditions, and a reasonable and supportable forecast that affects the collectability of the related financial asset. This amendment will affect trade receivables, off balance sheet credit exposures and any other financial assets not excluded from the scope of this amendment that have the contractual right to receive cash. The new standard was effective for annual and interim periods beginning after December 15, 2019. We have updated our historical losses and our allowance for credit losses as a result of the adoption of this ASU, which did not have a material impact on our consolidated financial statements. In March 2020, the Securities and Exchange Commission (SEC) issued a final rule that amended the disclosure requirements under SEC Regulation S-X Rule 3-10, Financial Statements of Guarantors and Issuers of Guaranteed Securities Registered or Being Registered. The final rule is based on the premise that the primary source of information that investors in guaranteed debt rely on is the consolidated financial statements of the parent company. The final rule replaces the previous requirement to provide separate condensed consolidating financial information of the guarantors. The final rule is effective for filings on or after January 4, 2021, and early adoption is permitted. We have elected to early adopt this rule which resulted in the removal of the supplemental guarantor financial information. 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. This ASU provides practical expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships and other transactions affected by reference rate reform if certain criteria are met. This ASU is applicable to our contracts that reference LIBOR. The amendments may be applied through December 31, 2022. We will apply this guidance to transactions and modifications of these arrangements going forward. NEW ACCOUNTING STANDARDS In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740) - Simplifying the Accounting for Income Taxes, which removes certain exceptions, such as the general methodology for calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year, and simplifies the accounting for income taxes in areas such as franchise tax (or similar tax) that is partially based on income. The new standard is effective for annual and interim periods beginning after December 15, 2020. We do not believe this ASU will have a material impact on our consolidated financial statements. We reviewed all other new accounting pronouncements issued in the period and concluded that they are not applicable to our business.
