Accounting Standards Update 2019-12 [Member]
Accounting Standards Update and Change in Accounting Principle [Text Block]	us-gaap_NewAccountingPronouncementsAndChangesInAccountingPrinciplesTextBlock	In December 2019, the Financial Accounting Standards Board ("FASB") issued Accounting Standard Update No. 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes.” This standard simplifies the accounting for income taxes by eliminating certain exceptions to the guidance in Topic 740 related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. The standard also simplifies aspects of the accounting for franchise taxes and enacted changes in tax laws or rates and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill. This update is effective for fiscal years beginning after December 15, 2020 and for interim periods within that year. Early adoption is permitted. We adopted this standard on October 1, 2021 with immaterial impact on our Consolidated Financial Statements.

Accounting Standards Update and Change in Accounting Principle [Text Block]	us-gaap_NewAccountingPronouncementsAndChangesInAccountingPrinciplesTextBlock	In June 2016, FASB issued Accounting Standard Update No. 2016-13, Financial Instruments – Credit Losses (“ASU 2016-13”), which requires companies to consider historical experiences, current market conditions and reasonable and supportable forecasts in the measurement of expected credit losses, with further clarifications made in April 2019 and May 2019 with the issuances of Accounting Standard Updates No. 2019-04 and 2019-05. This update is effective for fiscal years beginning after December 15, 2019 and for interim periods within those fiscal years. We adopted this standard on October 1, 2020, using a modified retrospective transition method through a cumulative-effect adjustment to beginning retained earnings in the period of adoption. As a result, we recorded an increase in the Allowance for Credit Losses of $284, an increase to Deferred Tax Assets of $70, and a decrease to Retained Earnings of $214.
