Income Tax (Topic 740) In December 2019, FASB issued ASU No. 2019-12, "Simplifying the Accounting for Income Taxes" ("ASU No. 2019-12") | The amendments in this guidance reflect the FASB’s effort to reduce the complexity of accounting standards while maintaining or enhancing the helpfulness of information provided to financial statement users. Changes include treatment of Hybrid tax regimes, tax basis step-up in goodwill obtained in a transaction that is not a business combination, separate financial statements of legal entities not subject to tax, intraperiod tax allocation, ownership changes in investments, interim-period accounting for enacted changes in tax law, year-to-date loss limitation in interim-period tax accounting, income statement presentation of tax benefits of tax-deductible dividends, and impairment of investment in qualified affordable housing projects accounted for under the equity method. | Fiscal years beginning after December 15, 2020 with early adoption permitted. | We adopted this amendment on January 1, 2021. We evaluated ASU No. 2019-12 and determined that there was no material impact on our Consolidated Financial Statements.
Compensation-Retirement Benefits-Defined Benefit Plans - General (Subtopic 715-20), In August 2018, the FASB issued ASU No. 2018-14, "Changes to the Disclosure requirements for defined benefit plans" ("ASU No. 2018-14") | This amendment removes certain disclosures that are not considered cost beneficial, and helps clarify certain required disclosures along with adding additional disclosures. This impacts employers that sponsor defined benefit pension and/or other postretirement plans. The amendment clarifies guidance in ASC 715-20-50-3 to disclose projected benefit obligation (PBO) and accumulated benefit obligation (ABO). | Fiscal years ending after December 15, 2020 with early adoption permitted. | We adopted ASU No. 2018-14 on December 31, 2020 on a retroactive basis and applied to each comparative period presented in our Consolidated Financial Statements. The adoption of ASU No. 2018-14 did not have a material impact on our Consolidated Financial Statements.
