Recently Adopted and Recently Issued Accounting Guidance | Recently Adopted and Recently Issued Accounting Guidance Recently Adopted Accounting Guidance. On January 1, 2021, the Company adopted changes issued by the Financial Accounting Standards Board (“FASB”) that were intended to simplify various aspects of accounting for income taxes by eliminating certain exceptions contained in existing guidance and amending other guidance to simplify several other income tax accounting matters. The adoption of this new guidance did not have a material impact on the Consolidated Financial Statements. On January 1, 2020, the Company adopted changes issued by the FASB related to the impairment model for expected credit losses. The new impairment model (known as the current expected credit loss (“CECL”) model) is based on expected losses rather than incurred losses. The Company recognizes as an allowance its estimate of expected credit losses. The CECL model applies to most debt instruments, trade receivables, lease receivables, financial guarantee contracts, and other loan commitments and requires the measurement of expected credit losses on assets including those that have a low risk of loss. The adoption of this new guidance did not have a material impact on the Consolidated Financial Statements. In August 2018, the FASB issued guidance that impacts disclosures for defined benefit pension plans and other postretirement benefit plans. These changes became effective for Howmet's annual report for the year ended December 31, 2020 which did not have a material impact on its Consolidated Financial Statements. Recently Issued Accounting Guidance. In September 2022, the FASB issued guidance to enhance the transparency of disclosures regarding supplier finance programs. These changes become effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, except for the amendment on rollforward information, which is effective for fiscal years beginning after December 15, 2023. Management is currently evaluating the impact of these changes on the Consolidated Financial Statements. In March 2020, the FASB issued amendments that provide optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform, if certain criteria are met. The amendments apply only to contracts and hedging relationships that reference London Inter-bank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued due to reference rate reform. These amendments are effective immediately and may be applied prospectively to contract modifications made and hedging relationships entered into or evaluated on or before December 31, 2022. In December 2022, the FASB deferred the sunset date to December 31, 2024. I n February 2023, the Company amended its Five-Year Revolving Credit Agreement to replace LIBOR with the term secured overnight financing rate (“Term SOFR”) as the reference rate for U.S. dollar-denominated loans (See Note R). Management has concluded that the impact of these changes is not expected to have a material impact on the Consolidated Financial Statements.
