Recent Accounting Pronouncements In March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU 2020 - 04” ) establishing Accounting Standards Codification (“ASC”) Topic 848, Reference Rate Reform. ASU 2020 - 04 contains practical expedients for reference rate reform related activities that impact debt, leases, derivatives and other contracts.
