New Accounting Pronouncements
Newly Adopted Accounting Standards
In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740). The new guidance is intended to enhance the transparency and decision usefulness of income tax disclosures. We adopted this standard in the fourth quarter of 2025. Upon adoption, this ASU did not have a material impact on the Company’s consolidated financial statements.
Recently Issued Accounting Standards
In November 2024, the FASB issued ASU No. 2024-03, Disaggregation of Income Statement Expenses (Subtopic 220-40). The new guidance requires the disaggregated disclosure of specific expense categories, including purchases of inventory, employee compensation, depreciation, and amortization, within relevant income statement captions. This ASU also requires disclosure of the total amount of selling expenses along with the definition of selling expenses. This ASU is effective for annual periods beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. Upon adoption, this ASU is not expected to have a material impact on the Company's financial statements and related disclosures.
In July 2025, the FASB issued ASU 2025‑05, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets. The new guidance provides a practical expedient that allows entities, when estimating expected credit losses on current accounts receivable and current contract assets, to assume that economic conditions as of the balance sheet date will not change over the remaining life of those assets. The amendments in this ASU are effective for annual reporting periods beginning after December 15, 2025, including interim periods within those annual periods, with early adoption permitted, and are required to be applied prospectively. Upon adoption, this ASU is not expected to have a material impact on the Company's financial statements and related disclosures.
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. The new guidance modernizes and simplifies the accounting for internal‑use software, including eliminating the existing three‑stage (preliminary project, application development, and post‑implementation/operation) model, and introduces revised criteria for capitalization that better reflect current agile and iterative software development practices, including considerations for software with significant development uncertainty. The amendments in this ASU are effective for annual reporting periods beginning after December 15, 2026, including interim periods within those annual periods, with various transition alternatives and early adoption permitted. We are currently evaluating the impact of this ASU on the Company’s financial statements and related disclosures and do not expect it to have a material impact.
In December 2025, the FASB issued ASU 2025‑10, Government Grants (Topic 832): Accounting for Government Grants Received by Business Entities. The new guidance provides authoritative recognition, measurement, presentation, and disclosure requirements for government grants to business entities in the form of monetary assets or tangible nonmonetary assets, largely leveraging the recognition and measurement framework in IAS 20, and
reduces diversity in practice that had arisen from analogies to other GAAP. For public business entities, the amendments in this ASU are effective for annual reporting periods beginning after December 15, 2028, including interim periods within those annual periods; for all other entities, the guidance is effective for annual periods beginning after December 15, 2029, including interim periods within those annual periods, with early adoption permitted. We are currently evaluating the impact of this ASU on the Company’s financial statements and related disclosures and do not expect it to have a material impact.

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.
