Accounting Standards Issued and 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). Additionally, in January 2025, the FASB issued ASU 2025-01 to clarify the effective date of ASU 2024-03. ASU 2024-03 provides guidance to expand disclosures related to the disaggregation of income statement expenses. The standard requires, in the notes to the financial statements, disclosure of specified information about certain costs and expenses which include purchases of inventory, employee compensation, depreciation, and intangible asset amortization that are included on the face of the statements of income. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, and for interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. ASU 2024-03 is effective for the Company beginning with its fiscal year ending March 31, 2028. The Company is in the process of evaluating the impact that the adoption of ASU 2024-03 will have on its disclosures. In September 2025, the FASB issued ASU 2025-06, Intangibles (Subtopic 350-40): Update to modernize the accounting for internal-use software costs. ASU 2025-06 removes all references to software project development stages and clarifies the recognition threshold that entities must meet to begin capitalizing costs. ASU 2025-06 is effective for the Company beginning with its fiscal year ending March 31, 2029. The Company is currently evaluating the impact of this standard and does not expect the adoption of ASU 2025-06 to have a material impact on its consolidated financial statements and disclosures.
