Certain amendments represent clarifications to or technical corrections of the current requirements. The following is a summary of the topics included in the update and which pertain to the Company: 1.Statement of cash flows (Topic 230): Requires an accounting policy disclosure in annual periods of where cash flows associated with derivative instruments and their related gains and loses are presented in the statement of cash flows; 2.Accounting changes and error corrections (Topic 250): Requires that when there has been a change in the reporting entity, the entity disclose any material prior-period adjustment and the effect of the adjustment on retained earnings in interim financial statements; 3.Earnings per share (Topic 260): Requires disclosure of the methods used in the diluted earnings-per-share computation for each dilutive security and clarifies that certain disclosures should be made during interim periods, and amends illustrative guidance to illustrate disclosure of the methods used in the diluted earnings per share computation; 4.Commitments (Topic 440): Requires disclosure of assets mortgaged, pledged, or otherwise subject to lien and the obligations collateralized; and 5.Debt (Topic 470): Requires disclosure of amounts and terms of unused lines of credit and unfunded commitments and the weighted-average interest rate on outstanding short-term borrowings. For public business entities, the amendments in ASU 2023-06 are effective on the date which the SEC’s removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective. If by June 30, 2027, the SEC has not removed the applicable requirement from Regulation S-X or Regulation S-K, the pending content of the related amendment will be removed from the codification and will not become effective for any entity. Early adoption is not permitted and the amendments are required to be applied on a prospective basis. The Company expects the adoption of this standard will not have a material impact on its Consolidated Financial Statements. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The amendments in this update are intended to improve income tax disclosure requirements, primarily through enhanced disclosures related to the existing requirements to disclose a rate reconciliation, income taxes paid and certain other required disclosures. Specifically, the amendments in this update: 1.Require that a public entity disclose, on an annual basis: (1) specific categories in the rate reconciliation and (2) additional information for reconciling items that meet a quantitative threshold. The update requires disclosure of such reconciling items according to requirements indicated in the update. 2.Require that all entities disclose certain disaggregated information regarding income taxes paid. 3.Require that all entities disclose certain disaggregated information regarding income tax expense. 4.Eliminate the requirement to: (1) disclose the nature and estimate of the range of reasonably possible changes in the unrecognized tax benefits balance in the next 12 months or (2) make a statement that an estimate of the range cannot be made. 5.Remove the requirement to disclose the cumulative amount of each type of temporary difference when a deferred tax liability is not recognized because of exceptions to comprehensive recognition of deferred taxes related to subsidiaries and corporate joint ventures. For public business entities, the amendments in ASU 2023-09 are effective for annual periods beginning after December 15, 2024. Adoption should be done on a prospective basis and retrospective application is permitted. In November 2024, the FASB issued ASU 2024-03, Income Statement–Reporting Comprehensive Income–Expense Disaggregation Disclosures (Subtopic 220-40). The amendments in this update require disclosure, in the notes to the financial statements, of specified information about certain costs and expenses. The amendments require that at each interim and annual reporting period an entity: 1.Disclose the amounts of (a) purchases of inventory, (b) employee compensation, (c) depreciation, (d) intangible asset amortization, and (e) depreciation, depletion, and amortization recognized as part of oil and gas-producing activities (or other amounts of depletion expense) included in each relevant expense caption. A relevant expense caption is an expense caption presented on the face of the income statement within continuing operations that contains any of the expense categories listed in (a)–(e). 2.Include certain amounts that are already required to be disclosed under current GAAP in the same disclosure as the other disaggregation requirements. 3.Disclose a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively. 4.Disclose the total amount of selling expenses and, in annual reporting periods, an entity’s definition of selling expenses. For public business entities, the amendments in ASU 2024-03 are effective for annual periods beginning after December 15, 2026 and interim periods beginning after December 15, 2027. Early adoption is permitted. The amendments in this update are to be applied either (1) prospectively to financial statements issued for reporting periods after the effective date of this update or (2) retrospectively to any or all prior periods presented in the financial statements. No standards were adopted during the three months ended March 31, 2025.
