Effect of New Accounting Pronouncements
Income Taxes
In December 31, 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires that an entity, on an annual basis, disclose additional income tax information, primarily related to the rate reconciliation and income taxes paid. The amendment in the ASU is intended to enhance the transparency and decision usefulness of income tax disclosures. We adopted this ASU as of December 31, 2025, which affected our income taxes disclosure. See Note 16 to these consolidated financial statements for further detail regarding the impact of this ASU.
Disaggregation of Income Statement Expenses
In November 2024, the FASB issued ASU 2024-03, Income Statement Reporting–Comprehensive Income–Expense Disaggregation Disclosures (Subtopic 220-40), Disaggregation of Income Statement Expenses. The standard update improves the disclosures about a public business entity’s expenses by requiring more detailed information about the types of expenses (including purchases of inventory, employee compensation, depreciation and amortization) included within income statement expense captions. The guidance will be effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. The standard updates are to be applied prospectively with the option for retrospective application. We are currently evaluating the impact of adoption of the standard update on its financial statement disclosures.
Accounting for Internal-Use Software
In September 2025, the FASB issued ASU 2025-06, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, which amends the guidance in ASC 350-40. The amendments modernize the recognition and disclosure requirements for internal-use software costs, introducing a more judgment-based approach while removing the previous “development stage” model. The amendment in the ASU is effective for all entities for fiscal years beginning after December 15, 2027, and interim periods within those fiscal years, with early adoption permitted. Entities may apply the guidance using a prospective, retrospective or modified transition approach. We are currently evaluating the impact of adoption of the standard update on our financial statement disclosures.

About New Standards Disclosures

New accounting standards disclosures describe recently adopted pronouncements and those not yet effective, along with management's assessment of their expected impact. This section provides an early warning system for upcoming changes to how a company reports its financial results, often years before the new rules take effect.

Key signals: when management describes a not-yet-adopted standard's impact as "material" or "still being evaluated," it signals potential significant changes to reported metrics upon adoption. Watch for standards that affect a company's core operations — for example, revenue recognition changes for software companies or lease accounting changes for retailers with large store footprints. The transition method chosen (full retrospective versus modified retrospective) affects comparability with prior periods. Companies that delay adoption to the latest permitted date may be struggling with implementation complexity. Compare the disclosed impact assessments against peers in the same industry to gauge whether management's expectations are reasonable.
