The following additional standards were applicable to the Company and adopted in 2021 and 2020, but did not have a material impact on the Company’s consolidated financial position or results of operation: • ASU 2021-06, “Presentation of Financial Statements (Topic 205), Financial Services – Depository and Lending (Topic 942) and Financial Services – Investment Companies (Topic 946)” • ASU 2021-01, “Reference Rate Reform (Topic 848)” • ASU 2020-08, “Codification Improvements to Subtopic 310-20, Receivables- Nonrefundable Fees and Other Costs” • ASU 2019-12, “Simplifying the Accounting for Income Taxes (Topic 740)” Accounting Standards Issued But Not Yet Adopted In March 2022, the FASB issued ASU 2022-01, "Derivatives and Hedging (Topic 815): Fair Value Hedging - Portfolio Layer Method," to provide clarification of and expand upon certain provisions of Topic 815 that became effective with the issuance of ASU 2017-12. The amendments in this update include the following provisions: (1) expand the current last-of-layer method to allow multiple hedged layers of a single closed portfolio and, accordingly, renaming the last-of-layer method to the portfolio layer method; (2) expand the scope of the portfolio layer method to include nonprepayable financial assets; (3) specify that eligible hedging instruments in a single-layer hedge may include spot-starting or forward-starting constant-notional swaps, or spot or forward-starting amortizing-notional swaps and that the number of hedged layers corresponds with the number of hedges designated; (4) provide additional guidance on the accounting for and disclosure of hedge basis adjustments that are applicable to the portfolio layer method whether a single hedged layer or multiple hedged layers are designated, and; (5) specify how hedge basis adjustments should be considered when determining credit losses for the assets included in the closed portfolio. The amendments in this update apply to all entities that elect to apply the portfolio layer method of hedge accounting in accordance with Topic 815. The amendments in this Update are effective for fiscal years beginning after December 15, 2022, and interim periods within those fiscal years. Upon adoption, any entity may designate multiple hedged layers of a single closed portfolio solely on a prospective basis. All entities are required to apply the amendments related to hedge basis adjustments under the portfolio layer method, except for those related to disclosures, on a modified retrospective basis by means of a cumulative-effect adjustment to the opening balance of retained earnings on the initial application date. Entities have the option to apply the amendments related to disclosures on a prospective basis from the initial application date or on a retrospective basis to each prior period presented after the date of adoption of the amendments in Update 2017-12. Within 30 days after the adoption, an entity may reclassify debt securities classified in the held-to-maturity category at the date of adoption to the available-for-sale category only if the entity applies portfolio layer method hedging to one or more closed portfolios that include those debt securities. The Company adopted this standard effective January 1, 2023 and elected to apply amendments to disclosures on a prospective basis, with no reclassification of debt securities from held to maturity to available for sale. The impact of adoption will not be material to the Company’s consolidated financial position or results of operations. In March 2022, the FASB issued ASU 2022-02, "Financial Instruments: Credit Losses (Topic 326) - Troubled Debt Restructurings and Vintage Disclosures." The amendments in this update cover two issues: (1) the elimination of TDR recognition and measurement guidance as prescribed by ASC 310-40 and, instead, require that an entity evaluate (consistent with the accounting for other loan modifications) whether the modification represents a new loan or a continuation of an existing loan. The amendments enhance existing disclosure requirements and introduce new requirements related to certain modifications of receivables made to borrowers experiencing financial difficulty; and, (2) for public business entities, the requirement that an entity disclose current-period gross write-offs by year of origination for financing receivables and net investment in leases within the scope of Subtopic 326-20. Gross write-off information must be included in the vintage disclosures required for public business entities in accordance with paragraph 326-20-50-6, which requires that an entity disclose the amortized cost basis of financing receivables by credit quality indicator and class of financing receivable by year of origination. The amendments in this update are effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. For the elimination of recognition and measurement guidance on troubled debt restructurings by creditors in Subtopic 310-40, an entity may elect to apply a modified retrospective transition by means of a cumulative-effect adjustment to the opening retained earnings as of the beginning of the fiscal year of adoption, or a prospective approach applied to modifications occurring after the date of adoption. The remainder of amendments should be applied prospectively. The Company adopted this standard effective January 1, 2023 on a prospective bases for all amendments. The adoption of this standard will not be material to the Company’s consolidated financial position or results of operations.
