Nature of Operations and Significant Accounting Policies | Nature of Operations and Significant Accounting Policies Background CSX Corporation together with its subsidiaries ("CSX" or the “Company”), based in Jacksonville, Florida, is one of the nation's leading transportation companies. The Company provides rail-based transportation services including traditional rail service, the transport of intermodal containers and trailers, as well as other transportation services such as rail-to-truck transfers and bulk commodity operations. CSX's principal operating subsidiary, CSX Transportation, Inc. (“CSXT”), provides an important link to the transportation supply chain through its approximately 20,000 route-mile rail network and serves major population centers in 26 states east of the Mississippi River, the District of Columbia and the Canadian provinces of Ontario and Quebec. The Company's intermodal business links customers to railroads via trucks and terminals. CSXT is also responsible for the Company's real estate sales, leasing, acquisition and management and development activities, substantially all of which are focused on supporting railroad operations. Other entities In addition to CSXT, the Company’s subsidiaries include Quality Carriers, Inc. ("Quality Carriers"), CSX Intermodal Terminals, Inc. (“CSX Intermodal Terminals”), Total Distribution Services, Inc. (“TDSI”), Transflo Terminal Services, Inc. (“Transflo”), CSX Technology, Inc. (“CSX Technology”) and other subsidiaries. Quality Carriers is the largest provider of bulk liquid chemicals truck transportation in North America. CSX Intermodal Terminals owns and operates a system of intermodal terminals, predominantly in the eastern United States and also performs drayage services (the pickup and delivery of intermodal shipments) for certain customers. TDSI serves the automotive industry with distribution centers and storage locations. Transflo connects non-rail served customers to the many benefits of rail by transferring products from rail to trucks. The biggest Transflo markets are chemicals and agriculture, which includes shipments of plastics and ethanol. CSX Technology and other subsidiaries provide support services for the Company. NOTE 1. Nature of Operations and Significant Accounting Policies, continued Basis of Presentation In the opinion of management, the accompanying consolidated financial statements contain all normal, recurring adjustments necessary to fairly present the consolidated financial statements and accompanying notes. Where applicable, prior year information has been reclassified to conform to the current presentation. Pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”), certain information and disclosures normally included in the notes to the annual financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been omitted from these interim financial statements. CSX suggests that these financial statements be read in conjunction with the audited financial statements and the notes included in CSX's most recent annual report on Form 10-K and any subsequently filed current reports on Form 8-K. Fiscal Year The Company's fiscal periods are based upon the calendar year. Except as otherwise specified, references to “first quarter(s)” or “three months” indicate CSX's fiscal periods ending March 31, 2025 and March 31, 2024, and references to "year-end" indicate the fiscal year ended December 31, 2024. New Accounting Pronouncements In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures. This standard update requires additional interim and annual disclosures about a company’s income taxes, including more detailed information around the annual rate reconciliation and income taxes paid. The Company is required to adopt the guidance for its 2025 annual report filed on Form 10-K, though early adoption is permitted. The Company is currently evaluating the impact of these amendments on its disclosures, but this standard update will not impact the Company's results of operations or financial position. In November 2024, the FASB issued ASU 2024-03, Disaggregation of Income Statement Expenses. This standard update requires additional disclosures about certain expenses in commonly presented expense captions. The Company is required to adopt the guidance for its 2027 annual report filed on Form 10-K, though early adoption is permitted. The Company is currently evaluating the impact of these amendments on its disclosures, but this standard update will not impact the Company's results of operations or financial position. Revision of Prior Period Financial Statements During second quarter 2024, CSX completed a review of the accounting treatment for engineering scrap and certain engineering support labor and identified misstatements between the balance sheet and operating expense in previously issued financial statements. In accordance with the Accounting Standards Codification (“ASC”) Topic 250, Accounting Changes and Error Corrections, the Company evaluated the materiality of the errors on the previously presented financial statements and determined that they did not result in a material misstatement to the financial condition, results of operations, or liquidity for any of the impacted periods. However, the Company determined that the effect of recording the misstatements during the second quarter of 2024 would be material to the annual 2024 consolidated financial statements. As a result, the Company revised its previously issued consolidated financial statements. For comparative purposes, the Company has also made corrections to the consolidated financial statements and applicable notes for the first quarter 2024 results presented in this Form 10-Q. See the 2024 annual report filed on Form 10-K for additional information and quantification of prior period restatement impacts.
