Adopted accounting standard

Accounting for joint ventures Effective January 1, 2025, the Company adopted the new Financial Accounting Standards Board (“FASB”) guidance requiring a joint venture to initially measure assets contributed and liabilities assumed at fair value as of the formation date. The adoption had no impact on the

Company’s Condensed Consolidated Statements of Operations and Condensed Consolidated Statements of Financial Position.

Pending accounting standards

Income tax disclosures In December 2023, the FASB issued guidance enhancing various aspects of income tax disclosures. The guidance requires a tabular reconciliation between statutory and effective income tax expense (benefit) with both amounts and percentages for a list of required categories. For certain required categories where an individual category is at least five percent of the statutory tax amount, the required category must be further broken out by nature and, for foreign tax effects, jurisdiction. Additionally, entities must disclose income taxes paid, net of refunds received, broken out between federal, state and foreign, and amounts paid, net of refunds received, to an individual jurisdiction when it is five percent or more of the total income taxes paid, net of refunds received.

Basic earnings per common share is computed using the weighted average number of common shares outstanding, including vested unissued participating restricted stock units. Diluted earnings per common share is computed using the weighted average number of common and dilutive potential common shares outstanding.
