Recent Accounting Pronouncements [Abstract]
NewAccountingPronouncementsAndChangesInAccountingPrinciples [TextBlock]	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. In January 2021, the FASB clarified the scope of that guidance with the issuance of ASU 2021-01, Reference Rate Reform: Scope. The new accounting rules provide optional expedients and exceptions for applying GAAP to contracts and other transactions affected by reference rate reform. The amendments in this standard can be adopted any time before the fourth quarter of 2022. The Company is currently in the process of evaluating the impact of adoption of the new rules on the Company’s financial condition, results of operations, cash flows and disclosures.
