Recently Adopted Accounting Developments

In  March 2024, the Financial Accounting Standards Board (FASB) issued ASU 2024-02, “Codification Improvements – Amendments to Remove References to the Concepts Statements”. This ASU contains amendments to the Codification that remove references to various Concepts Statements. In most instances, the references are extraneous and not required to understand or apply the guidance. In other instances, the references were used in prior Statements to provide guidance in certain topical areas. ASU 2024-02 was effective for the Company on  January 1, 2025 and there was no material impact to the consolidated financial statements. 

In December 2023, the Financial Accounting Standards Board (FASB) issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” The amendments in this ASU require an entity to disclose specific categories in the rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold, which is greater than five percent of the amount computed by multiplying pretax income by the entity’s applicable statutory rate, on an annual basis. Additionally, the amendments in this ASU require an entity to disclose the amount of income taxes paid (net of refunds received) disaggregated by federal, state, and foreign taxes and the amount of income taxes paid (net of refunds received) disaggregated by individual jurisdictions that are equal to or greater than five percent of total income taxes paid (net of refunds received). Lastly, the amendments in this ASU require an entity to disclose income (or loss) from continuing operations before income tax expense (or benefit) disaggregated between domestic and foreign and income tax expense (or benefit) from continuing operations disaggregated by federal, state, and foreign. This ASU is effective for annual periods beginning after December 15, 2024. The amendments should be applied on a prospective basis; however, retrospective application is permitted. ASU 2023-09 was effective for the Company for the annual period beginning January 1, 2025. Refer to Note 11 for updated disclosures due to the adoption of ASU 2023-09.

Impact of Recently Issued Accounting Pronouncements

In  November 2024, the Financial Accounting Standards Board (FASB) issued ASU 2024-03, “Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses.” ASU 2024-03 requires public companies to disclose, in the notes to the financial statements, specific information about certain costs and expenses at each interim and annual reporting period. This includes disclosing amounts related to employee compensation, depreciation, and intangible asset amortization. In addition, public companies will need to provide qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively. The FASB subsequently issued ASU 2025-01, “Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date”, which amends the effective date of ASU 2024-03 to clarify that all public business entities are required to adopt the guidance in ASU 2024-03 in annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. Early adoption of ASU 2024-03 is permitted. Implementation of ASU 2024-03 may be applied prospectively or retrospectively. The Company does not expect the adoption of ASU 2024-03 to have a material impact on its consolidated financial statements.

In November 2025, the Financial Accounting Standards Board (FASB) issued ASU 2025-08, “Financial Instruments—Credit Losses (Topic 326): Purchased Loans.” The amendments in this ASU expand the population of acquired financial assets accounted for using the gross-up approach. Acquired loans (excluding credit cards) are deemed purchased seasoned loans and accounted for using the gross-up approach upon acquisition if criteria established by the new guidance are met. This change aims to enhance comparability, consistency, and better reflect the economics of acquiring financial assets. This ASU is effective for annual reporting periods beginning after December 15, 2026, and for interim reporting periods within those annual reporting periods. Early adoption is permitted in an interim or annual reporting period in which financial statements have not yet been issued or made available for issuance. If an entity adopts this ASU in an interim reporting period, it should apply it as of the beginning of that interim reporting period or the beginning of the annual reporting period that includes that interim reporting period. The Company does not expect the adoption of ASU 2025-08 to have a material impact on its consolidated financial statements.
