Accounting Changes and Error Corrections [Abstract]

NOTE 2. NEW ACCOUNTING PRONOUNCEMENTS

In December 2025, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2025‑12, Codification Improvements, as part of its ongoing initiative to make incremental improvements to the Accounting Standards Codification. The amendments address a broad range of Topics and include technical corrections, clarifications, and other minor improvements intended to enhance the usability and consistency of U.S. GAAP. The amendments are not expected to significantly affect current accounting practice or result in significant implementation costs for most entities. The amendments are effective for annual periods beginning after December 15, 2026, and for interim periods within those annual periods. Early adoption is permitted. The Company is currently evaluating the impact of this ASU on its consolidated financial statements and does not expect the adoption of this ASU to have a material impact on its financial position, results of operations, or cash flows

In December 2025, the FASB issued ASU No. 2025‑11, Interim Reporting (Topic 270): Narrow‑Scope Improvements, which clarifies and reorganizes the guidance in Topic 270 to improve navigability and consistency in interim reporting. The amendments clarify which entities are subject to Topic 270, specify the form and content of interim financial statements and accompanying notes, and provide a comprehensive list of required interim disclosures. The ASU also introduces a disclosure principle requiring entities to disclose events and changes since the end of the most recent annual reporting period that have a material impact on the entity. The amendments are not intended to change the fundamental nature of interim reporting or significantly expand or reduce existing interim disclosure requirements, but rather to clarify existing guidance. For public business entities, the amendments are effective for interim reporting periods within fiscal years beginning after December 15, 2027. The Company is currently evaluating the impact of this ASU

on its interim financial statement disclosures. The Company does not expect the adoption of this ASU to have a material impact 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.

This ASU also supersedes Subtopic 350-50 and consolidates all website development guidance into Subtopic 350-40. This ASU is effective for fiscal years beginning after December 15, 2027, including subsequent interim periods. The Company is currently in the process of evaluating the financial statement impact of this ASU.
