Accounting Policies [Abstract]
New Accounting Pronouncements, Policy [Policy Text Block]	Recent accounting standards not yet adopted The following discusses the accounting standard(s) not yet adopted that will, or are expected to, result in a significant change in practice and/or have a significant financial impact on our financial position, results of operations or cash flows. In June 2016, the Financial Accounting Standards Board (FASB) issued guidance ASU No.* 2016-13 Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments* which changes the accounting for credit losses for certain instruments, including trade receivables, from an incurred loss method to a current expected loss method. The measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts. The guidance, and subsequent guidance related to the topic, is effective for our annual and interim periods beginning in 2023 and must be adopted on a modified retrospective approach through cumulative-effect adjustment to retained earnings as of January 1, 2023. Based on the nature of our current receivables and our credit loss history, we do not expect the adoption of the guidance to have a significant impact on our results of operations, financial position, or cash flows.
