Recent Accounting Pronouncements
Income Taxes
In December 2019, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2019-12, Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes, eliminates certain exceptions within Accounting Standards Codification (“ASC”) 740, Income Taxes, and clarifies certain aspects of the current
guidance to promote consistency among reporting entities. ASU 2019-12 is effective for our fiscal year beginning after December 15, 2020. We adopted this guidance as of January 1, 2021 and the adoption did not have an impact on our condensed consolidated financial statements.
Reference Rate Reform
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. ASU 2020-04, which provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. Companies can apply the ASU immediately, however, the guidance will only be available until December 31, 2022. We are currently evaluating the impact that adopting this new accounting standard would have on our condensed consolidated financial statements and related disclosures.
In January 2021, the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848): Scope. The amendments in ASU 2021-01 provide optional expedients to the current guidance on contract modification and hedge accounting from the expected market transition from LIBOR and other interbank offered rates to alternative reference rates. The guidance generally can be applied to applicable contract modifications through December 31, 2022. We are currently evaluating the impact that adopting this new accounting standard would have on our condensed consolidated financial statements and related disclosures.
Codification Improvements
In October 2020, the FASB issued ASU 2020-10, Codification Improvements. The amendments in this ASU represent changes to clarify the ASC, correct unintended application of guidance, or make minor improvements to the ASC that are not expected to have a significant effect on current accounting practice or create a significant administrative cost to most entities. ASU 2020-10 is effective for annual periods beginning after December 15, 2020 and interim periods within those annual periods, with early adoption permitted. The amendments in this ASU should be applied retrospectively. We adopted this guidance as of January 1, 2021 and the adoption did not have an impact on our condensed consolidated financial statements.
Business Combinations
In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires entities to apply Topic 606 to recognize and measure contract assets and contract liabilities in a business combination. ASU 2021-08 is effective for our fiscal year beginning after December 15, 2022. We are currently evaluating the impact that adopting this new accounting standard would have on our condensed consolidated financial statements.
