ORGANIZATION AND DESCRIPTION OF THE BUSINESS AND FINANCIAL STATEMENT PRESENTATION
ORGANIZATION AND DESCRIPTION OF THE BUSINESS AND FINANCIAL STATEMENT PRESENTATION	NOTE A – ORGANIZATION AND DESCRIPTION OF THE BUSINESS AND FINANCIAL STATEMENT PRESENTATION Organization and Description of Business ArcBest Corporation^™ (the “Company”) is a multibillion-dollar integrated logistics company that leverages technology and a full suite of shipping and logistics solutions to meet customers’ supply chain needs. The Company, which started over a century ago as a local freight hauler, is now a logistics powerhouse with global reach. The Company’s operations are conducted through its two reportable operating segments: Asset-Based, which consists of ABF Freight System, Inc. and certain other subsidiaries (“ABF Freight”), and Asset-Light, which includes MoLo Solutions, LLC (“MoLo”), Panther Premium Logistics^® (“Panther”), and certain other subsidiaries. References to the Company in this Annual Report on Form 10-K are primarily to the Company and its subsidiaries on a consolidated basis. The Asset-Based segment represented approximately 63% of the Company’s 2023 total revenues before other revenues and intercompany eliminations. As of December 2023, approximately 82% of the Asset-Based segment’s employees were covered under a collective bargaining agreement, the ABF National Master Freight Agreement (the “2023 ABF NMFA”), with the International Brotherhood of Teamsters (the “IBT”), which was ratified on June 30, 2023 by a majority of ABF Freight’s IBT member employees. A majority of the 2023 ABF NMFA supplements also passed. The remaining supplements were ratified on July 7, 2023. The 2023 ABF NMFA was implemented on July 16, 2023, effective retroactive to July 1, 2023, and will remain in effect through June 30, 2028. Financial Statement Presentation Consolidation: The consolidated financial statements include the accounts of the Company and its subsidiaries. All significant intercompany accounts and transactions are eliminated in consolidation. Segment Information: The Company uses the “management approach” for determining its reportable segment information. The management approach is based on the way management organizes the reportable segments within the Company for making operating decisions and assessing performance. See Note O for further discussion of segment reporting. Use of Estimates: The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual amounts may differ from those estimates. Reclassifications: On February 28, 2023, the Company sold FleetNet America, Inc. (“FleetNet”), a wholly owned subsidiary and reportable operating segment of the Company, for an aggregate adjusted cash purchase price of $100.9 million, including post-closing adjustments. The sale of FleetNet was a strategic shift for the Company as it exited the fleet roadside assistance and maintenance management business; therefore, the sale was accounted for as discontinued operations. As such, historical results of FleetNet have been excluded from both continuing operations and segment results for all periods presented, and reclassifications have been made to the prior-period financial statements to conform to the current-year presentation. Related assets and liabilities associated with FleetNet are classified as discontinued operations in the consolidated balance sheets for all periods presented. The cash flows related to the discontinued operations have not been segregated and are included in the consolidated statements of cash flows. Unless otherwise indicated, all amounts in this Annual Report on Form 10-K refer to continuing operations, including comparisons to the prior year. For more information on the Company’s discontinued operations, see Note D. Certain reclassifications have been made to the prior period presentation of other long-term liabilities to conform to the current-year presentation of the contingent consideration liability on a separate line in the consolidated balance sheets. For the years ended December 31, 2022 and 2021, certain reclassifications have been made between operating expenses lines of the Asset-Light segment to conform to the current-year presentation of certain facility rent expenses. There was no impact on total liabilities or total operating expenses as a result of these reclassifications.
