Recent Accounting Pronouncements
See the recent accounting pronouncements discussion below for information pertaining to the effects of recently adopted and other recent accounting pronouncements.
Accounting Pronouncements Adopted in 2025
In August 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-05, Business Combinations—Joint Venture Formations (Subtopic 805-60): Recognition and Initial Measurement (“ASU 2023-05”) to clarify existing guidance and reduce diversity in practice in the accounting for joint ventures. ASU 2023-05 addressed the accounting for contributions made to a joint venture upon formation in a joint venture’s separate financial statements. The provisions of this ASU required that a joint venture initially measure all contributions received upon its formation at fair value, largely consistent with Accounting Standards Codification (“ASC”) Topic 805, Business Combinations (“ASC 805”). The amendments in this ASU were not applicable to the formation of proportionately consolidated joint ventures. ASU 2023-05 was effective prospectively for all joint ventures with a formation date on or after January 1, 2025, with early adoption permitted on a retrospective basis for joint ventures formed before January 1, 2025. The Company adopted this ASU prospectively in the first quarter of 2025, and its adoption did not have a material effect on the Company’s consolidated financial statements.
In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”) to enhance transparency and decision usefulness of income tax disclosures. ASU 2023-09 requires greater standardization and disaggregation of categories within an entity’s tax rate reconciliation disclosure, as well as disclosure of income taxes paid by jurisdiction, among other requirements. ASU 2023-09 is effective for annual periods beginning after December 15, 2024, with early adoption permitted. ASU 2023-09 was effective on a prospective basis, with retrospective application permitted. The Company adopted this ASU prospectively as of and for the year-ended December 31, 2025, and its adoption only impacted the Company’s disclosures, and did not have a material effect on its consolidated financial statements or results of operations. See Note 13 - Income Taxes for additional information.
Recently Issued Accounting Pronouncements Not Yet Adopted
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 (“ASU 2024-03”) to enhance the transparency and clarity of the components of specific expense categories in the income statement. ASU 2024-03 requires disclosure of additional information about specific expense categories underlying certain income statement expense line items. In January 2025, the FASB issued ASU 2025-01, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses: Clarifying the Effective Date to clarify that all public business entities are required to adopt the guidance in annual periods beginning after December 15, 2026, and interim periods within annual periods beginning after December 15, 2027. Early adoption is permitted. The amendments in ASU 2024-03, and its related clarifying ASU, should be applied prospectively, with retrospective application permitted. The Company is currently evaluating the impact this ASU will have on its disclosures.
In May 2025, the FASB issued ASU 2025-03, Business Combinations (Topic 805) and Consolidation (Topic 810): Determining the Accounting Acquirer in the Acquisition of a Variable Interest Entity (“ASU 2025-03”). ASU 2025-03 clarifies the guidance in determining the accounting acquirer in a business combination effected primarily by exchanging equity interests when the acquiree is a variable interest entity that meets the definition of a business. ASU 2025-03 is effective for fiscal years beginning after December 15, 2026, including interim periods within those fiscal years, with early adoption permitted. ASU 2025-03 is required to be applied prospectively to any acquisition transaction that occurs after the initial application date. The Company does not expect that this ASU will have a material effect on its consolidated financial statements.
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 (“ASU 2025-05”). ASU 2025-05 provides a practical expedient that permits an entity to assume that conditions at the balance sheet date remain unchanged over the life of the asset when estimating expected credit losses for current accounts receivable and current contract assets. ASU 2025-05 is effective for fiscal years beginning after December 15, 2025, including interim periods within those fiscal years, with early adoption permitted. The amendments in ASU 2025-05 should be applied prospectively. The Company does not expect that this ASU will have a material effect on its consolidated financial statements.
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 (“ASU 2025-06”). ASU 2025-06 modernizes the accounting for internal-use software by eliminating the previous stage-based capitalization model so that the guidance is neutral to different software development methods. ASU 2025-06 is effective for fiscal years beginning after December 15, 2027, including interim periods within those fiscal years, with early adoption permitted. The amendments in ASU 2025-06 should be applied prospectively, with retrospective application or a modified transition approach permitted. The Company is currently evaluating the impact this ASU will have on its consolidated financial statements.
In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements (“ASU 2025-11”). ASU 2025-11 improves existing guidance within ASC Topic 270 by clarifying the scope and applicability of the standard and by providing a comprehensive list of interim disclosure requirements. ASU 2025-11 also establishes a principle to disclose events since the end of the last annual reporting period that have a material impact on the entity. ASU 2025-11 is effective for interim reporting periods within annual reporting periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact this ASU will have on its 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.
