Accounting Standards Update and Change in Accounting Principle [Text Block] | 3. Accounting Pronouncements In December 2019, the FASB issued Accounting Standards Update No. 2019-12 (ASU 2019-12), Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which simplifies the accounting and disclosure requirements for income taxes by clarifying existing guidance to improve consistency in application of Accounting Standards Codification (ASC) 740. The Company adopted the ASU on January 1, 2021 (the effective date), and it did not have a material impact on the Company’s Consolidated Financial Statements and related disclosures. In March 2020, the FASB issued Accounting Standards Update No. 2020-04 (ASU 2020-04), Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional expedients and exceptions for applying GAAP principles to contracts, hedging relationships, and other transactions that reference London Interbank Offered Rate (LIBOR) or another reference rate expected to be discontinued due to reference rate reform. This guidance was effective beginning on March 12, 2020, and can be adopted on a prospective basis no later than December 31, 2022, with early adoption permitted. The Company is currently evaluating the effect that the new guidance will have on our Consolidated Financial Statements and related disclosures. In November 2021, the FASB issued Accounting Standards Update No. 2021-10 (ASU 2021-10), Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance, which requires business entities to provide certain disclosures when they have received government assistance and use a grant or contribution accounting model by analogy to other accounting guidance. The guidance is effective for fiscal years beginning after December 15, 2021. The Company is currently evaluating the effect that the new guidance will have on our related disclosures.
