New Accounting Pronouncement or Change in Accounting Principle, Description | Effects of Reference Rate Reform In March 2020, the FASB issued ASU 2020-04, which provides relief from accounting analysis and impacts that may otherwise be required for modifications to agreements necessitated by reference rate reform. It also provides optional expedients to enable the continuance of hedge accounting where certain hedging relationships are impacted by reference rate reform. This optional guidance is effective immediately, and available to be used through December 31, 2022. We are assessing the impact that reference rate reform and the related adoption of this guidance may have on our financial statements. |  |
