Accounting Policies [Abstract]
Accounting and disclosure charges	Accounting Pronouncements Adopted in 2022 In December 2019, the FASB issued ASU No. 2019-12 Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. The new guidance removes certain exceptions to the general principles for income taxes and also improves consistent application of accounting by clarifying or amending existing guidance. The new standard was adopted effective December 1, 2021. There was no material impact to our consolidated financial statements. In March 2020, the FASB issued ASU No. 2020-04 Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting that provides optional expedients for a limited period of time for accounting for contracts, hedging relationships, and other transactions affected by the London Interbank Offered Rate (LIBOR) or other reference rates expected to be discontinued. These optional expedients can be applied from March 2020 through December 31, 2022. LIBOR is used as a reference rate on our variable rate debt, including our revolving credit facility, synthetic lease, interest rate swaps, and cross currency interest rate swaps. The phase out of LIBOR reference rates will occur at different dates and began on January 1, 2022. Our adoption of this new standard occurred during the three months ended February 28, 2022, in conjunction with the first phase-out of a LIBOR reference rate. There was no material impact to our consolidated financial statements during the three months ended February 28, 2022, nor do we expect the adoption of this standard to have a material impact on our consolidated financial statements during the LIBOR transition period.
