Recently Issued Accounting Pronouncements
Accounting for Government Grants Received by Business Entities (ASU 2025-10)
In December 2025, the FASB issued an accounting standards update to establish authoritative guidance on recognition, measurement, presentation, and disclosure of government grants received by business entities. The amendments define government grants as transfers of monetary or tangible non-monetary assets from a government to a business entity (excluding exchange transactions) and leverages principles from IAS 20 while tailoring certain U.S. GAAP requirements. The amendments are effective for annual periods beginning after December 15, 2028, for public business entities, with early adoption is permitted. The transition options include modified prospective, modified retrospective, or full retrospective. The Company is in the process of evaluating the impact of this standard on the Company's consolidated financial statements.
Hedge Accounting Improvements (ASU 2025-09)
In November 2025, the FASB issued an accounting standards update to clarify and improve certain aspects of hedge accounting guidance in ASC 815. The amendments address five specific areas: (1) similar risk assessment for cash flow hedges, (2) hedging interest payments on choose-your-rate debt, (3) cash flow hedges of nonfinancial forecasted transactions, (4) net written options as hedging instruments, and (5) foreign currency-denominated debt designated as both a hedging instrument and hedged item. The amendments more closely align hedge accounting with the economics of an entity's risk management activities. The amendments are effective for annual periods beginning after December 15, 2026, for public business entities with early adoption permitted. Entities should apply the new guidance prospectively. The Company is in the process of evaluating the impact of this standard on the Company's consolidated financial statements.
Targeted Improvements to the Accounting for Internal-Use Software (ASU 2025-06)
In September 2025, the Financial Accounting Standards Board ("FASB") issued an accounting standards update to modernize the accounting for software costs to increase the operability of the recognition guidance considering different methods of software development and clarify the criteria for capitalizing software costs. The amendments are effective for annual reporting periods beginning after December 15, 2027 and interim reporting periods within those annual reporting periods, with an early adoption permitted as of the beginning of an annual reporting period. Entities should apply the new guidance either retrospectively, prospectively, or via a modified prospective transition method. The Company is in the process of evaluating the impact of this standard on the Company's consolidated financial statements.
Measurement of Credit Losses for Accounts Receivable and Contract Assets (ASU 2025-05)
In July 2025, the FASB issued an accounting standards update to add a practical expedient in developing reasonable and supportable forecasts as part of estimating expected credit losses. All entities may elect a practical expedient that assumes the current conditions as of the balance sheet date do not change for the remaining life of the asset. The amendments in this update are effective for annual reporting periods beginning after December 15, 2025 and interim reporting periods within those annual reporting periods, with early adoption permitted. Entities should apply the new guidance prospectively. The Company does not expect that this accounting standard, upon adoption, will have a material impact on the Company's consolidated financial statements.
Disaggregation of Income Statement Expenses (ASU 2024-03)
In November 2024, the FASB issued an accounting standards update requiring public entities to disclose, on an annual and interim basis, detailed information about the types of expenses in relevant expense captions presented on the face of the income statement, including amounts for inventory purchases, employee compensation, depreciation and amortization of intangible assets and a qualitative description for remaining amounts not separately disaggregated. Additionally, the update requires disclosure of total selling expenses, and in annual periods, an entity's definition of selling expenses. The amendments in this update are effective for annual reporting periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027 and are to be applied either prospectively or retrospectively. The Company is currently evaluating the impact of the update on the disclosures in the Company's consolidated financial statements.
Recently Adopted Accounting Standards
Income Taxes (Topic 740): Improvements to Income Tax Disclosures (ASU No.2023-09)
In December 2023, the FASB issued an accounting standards update to enhance the transparency and decision-usefulness of income tax disclosures and to provide information to better assess how an entity's operations and related tax risks and tax planning and operational opportunities affect its tax rate and prospects for future cash flows. For public business entities, the amendments in this update are effective for annual periods beginning after December 15, 2024, with an early adoption permitted. The amendments should be applied prospectively; however, retrospective application is permitted. The Company adopted this accounting standard in the 2025 annual period and applied the standard prospectively. The adoption of this ASU resulted in additional income tax disclosures (see Note 16).
Business Combinations—Joint Venture Formations (Subtopic 805-60): Recognition and Initial Measurement (ASU 2023-05)
In August 2023, the FASB issued an accounting standards update to address the accounting for contributions made to a joint venture, upon formation, in a joint venture's financial statements, and to provide decision-useful information to investors in a joint venture's financial statements and reduce diversity in practice. Under the update, upon formation, a joint venture should recognize and initially measure its assets and liabilities at fair value (with exceptions to fair value measurement that are consistent with guidance for business combinations). The amendments in this update become effective for all joint venture formations with a formation date on or after January 1, 2025. Additionally, a joint venture that was formed before January 1, 2025 may elect to apply the amendments retrospectively if it has sufficient information. Early adoption is permitted in any interim or annual period in which financial statements have not yet been issued, either prospectively or retrospectively. The Company adopted this accounting standard effective January 1, 2025 and the adoption did not have an impact on the Company's consolidated financial statements.

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.
