Adoption of New Accounting Standards
In December 2019, the Financial Accounting Standards Board ("FASB") issued ASU No. 2019-12, Income Taxes (Topic 740), which is intended to enhance various aspects of the accounting for income taxes. The new guidance updates the calculation of income taxes in an interim period when year-to-date losses exceed the anticipated loss for the year. We adopted this guidance in Q1 2021 on a prospective basis. The adoption of this guidance did not have a material effect on our consolidated financial statements.
In August 2018, the FASB issued ASU No. 2018-14, Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans, which amends ASC 715-20, Compensation - Retirement Benefits - Defined Benefit Plans - General. The amended guidance modifies the disclosure requirements for employers that sponsor defined benefit pension or other post-retirement plans by removing and adding certain disclosures for these plans. The eliminated disclosures include (a) the amounts in accumulated other comprehensive income expected to be recognized in net periodic benefit costs over the next fiscal year and (b) the effects of a one percentage point change in assumed health care cost trend rates on the net periodic benefit costs and the benefit obligation for post-retirement health care benefits. Additional disclosures include descriptions of significant gains and losses affecting the benefit obligation for the period. We adopted this guidance in Q4 2021. The adoption of this guidance modified our disclosures included in Note 15 but did not have a material effect on our consolidated financial statements.
In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326), which replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses. We adopted this guidance in Q1 2021 using a modified retrospective transition approach. The adoption of this guidance did not have a material effect on our consolidated financial statements or significantly impact our accounting policies or methods utilized to determine the allowance for credit losses. See Note 2 for additional information regarding our accounting policies related to the allowance for credit losses.
