Accounting Standards Update and Change in Accounting Principle [Abstract] |
New Accounting Pronouncements and Changes in Accounting Principles [Text Block] | New Accounting PronouncementsRecently Issued Accounting Standards 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. The amendments in this update provide optional guidance for a limited period of time to ease the potential burden for reference rate reform on financial reporting. Due to concerns about structural risks of interbank offered rates and, particularly, the risk of cessation of the London Interbank Offered Rate ("LIBOR"), regulators around the world have undertaken reference rate reform initiatives to identify alternative reference rates that are more observable or transaction based and less susceptible to manipulation. The amendments in this update apply only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued as a result of reference rate reform. Optional expedients may be applied to contracts that are modified as a result of the reference rate reform. Modifications of contracts within the scope of Topic 470, Debt, should be accounted for by prospectively adjusting the effective interest rate. Modifications of contracts within the scope of ASC 842, Leases, should be accounted for as a continuation of the existing contracts with no reassessments of the lease classification and the discount rate (incremental borrowing rate). Exceptions to Topic 815, Derivatives and Hedging, results in not having a dedesignation of a hedging relationship if certain criteria are met. The amendments in this ASU are effective for all entities as of March 12, 2020 through December 31, 2022. The impact of this ASU on our contracts has not been material.
