Summary of significant accounting policies

Basis of presentation — Our consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States (GAAP) for interim financial information. These statements are unaudited, but in the opinion of management include all adjustments (consisting only of normal recurring adjustments) necessary for a fair statement of the results for the interim periods. The results reported in these consolidated financial statements should not necessarily be taken as indicative of results that may be expected for the entire year. The financial information included herein should be read in conjunction with the consolidated financial statements in Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2025 (the 2025 Form 10-K). Certain prior year amounts have been reclassified to conform to the current presentation.

On January 1, 2026, we completed the previously announced sale of our Off-Highway business to Allison Transmission Holdings, Inc. The sale was consummated pursuant to the terms and conditions of the definitive agreement to sell that we entered in June 2025. A component of an entity is reported in discontinued operations after meeting the criteria for held for sale classification if the disposition represents a strategic shift that has, or will have, a major effect on the entity’s operations and financial results. We analyzed the quantitative and qualitative factors relevant to the divestiture of our Off-Highway business and determined that the conditions for discontinued operations presentation have been met.
