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 ArcBest Corporation^™ (the “Company”) is the parent holding company of freight transportation and integrated logistics businesses providing innovative solutions. The Company’s operations are conducted through its three reportable operating segments: Asset-Based, which consists of ABF Freight System, Inc. and certain other subsidiaries (“ABF Freight”); ArcBest, the Company’s asset-light logistics operation; and FleetNet. References to the Company in this Quarterly Report on Form 10-Q are primarily to the Company and its subsidiaries on a consolidated basis. The Asset-Based segment represented approximately 64% of the Company’s total revenues before other revenues and intercompany eliminations for the three months ended March 31, 2021. As of March 2021, approximately 82% of the Asset-Based segment’s employees were covered under a collective bargaining agreement, the ABF National Master Freight Agreement (the “2018 ABF NMFA”), with the International Brotherhood of Teamsters (the “IBT”), which will remain in effect through June 30, 2023. Financial Statement Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States and applicable rules and regulations of the Securities and Exchange Commission (the “SEC”) pertaining to interim financial information. Accordingly, these interim financial statements do not include all information or footnote disclosures required by accounting principles generally accepted in the United States for complete financial statements and, therefore, should be read in conjunction with the audited financial statements and accompanying notes included in the Company’s 2020 Annual Report on Form 10-K and other current filings with the SEC. In the opinion of management, all adjustments (which are of a normal and recurring nature) considered necessary for a fair presentation have been included. 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. The Company considered the impact of the novel coronavirus (“COVID-19”) pandemic on the estimates and assumptions used in preparation of the Company’s consolidated financial statements as of and for the three months ended March 31, 2021. Given the uncertainties regarding the economic environment and the impact of the COVID-19 pandemic on our business, it is possible that these estimates and assumptions may materially change in future periods. Reclassifications: Certain reclassifications have been made to the prior period presentation in the consolidated statements of cash flows to conform to the current year presentation. The multiemployer pension fund withdrawal liability, which was associated with the 2018 transition agreement and withdrawal from the New England Teamsters and Trucking Industry Pension Fund, was previously presented in a separate line of changes in operating assets and liabilities in the consolidated statements of cash flows and has been reclassed to the accounts payable, accrued expenses, and other liabilities line. There was no impact on net cash used in operating activities or total cash and cash equivalents as a result of the reclassification. Adopted Accounting Pronouncements ASC Topic 740, Income Taxes, was amended to simplify the accounting for income taxes to improve consistency of accounting methods and remove certain exceptions. The amendment was effective for the Company on January 1, 2021, and did not impact the consolidated financial statements and disclosures. Accounting Pronouncements Not Yet Adopted Management believes there is no other new accounting guidance issued but not yet effective that is relevant to the Company’s current financial statements.
