New U.S. GAAP Accounting Pronouncements The new accounting pronouncements applicable to the Company are detailed below: Accounting Standards Update 2025 01 — Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220 40): Clarifying the Effective Date The Board issued Update 2024-03 on November 4, 2024. Update 2024-03 states that the amendments are effective for public business entities for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Following the issuance of Update 2024-03, the Board was asked to clarify the initial effective date for entities that do not have an annual reporting period that ends on December 31 (referred to as non-calendar year-end entities). Because of how the effective date guidance was written, a non-calendar year-end entity may have concluded that it would be required to initially adopt the disclosure requirements in Update 2024-03 in an interim reporting period, rather than in an annual reporting period.

Under a prospective transition approach, an entity should apply the amendments in this Update to new software costs incurred as of the beginning of the period of adoption for all projects, including in-process projects.
