Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation - The Company prepares its Condensed Consolidated Financial Statements in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The Condensed Consolidated Balance Sheet as of March 31, 2026 was derived from audited financial statements included in the Annual Report on Form 10-K for the year ended March 31, 2026 (“Fiscal 2026 Form 10-K”). The accompanying unaudited Condensed Consolidated Financial Statements contain all adjustments, of a normal recurring nature, necessary to present fairly its financial position as of June 30, 2026, the results of operations for the three months ended June 30, 2026 and cash flows for the three months ended June 30, 2026. The interim Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements, including the notes thereto, filed in the Company’s Fiscal 2026 Form 10-K. Presentation - Prior period segment results and related disclosures have been recast to conform to the current period segment presentation. See “Note 14. Business Segment Information” for additional information.
Principles of Consolidation	Principles of Consolidation - The Condensed Consolidated Financial Statements include the Company, its wholly-owned subsidiaries, its majority-owned subsidiaries and variable interest entities of which the Company is the primary beneficiary. The Company uses the equity method of accounting for equity investments where it exercises significant influence but does not hold a controlling financial interest. Such investments are recorded in Other assets in the Condensed Consolidated Balance Sheets and the related equity earnings from these investments are included in Equity in net income of unconsolidated affiliates in the Condensed Consolidated Statements of Operations. All intercompany balances and transactions have been eliminated in consolidation.
Recent Accounting Guidance	Recent Accounting Guidance Recently Adopted Accounting Pronouncement Measurement of Credit Losses for Accounts Receivable and Contract Assets - In July 2025, the FASB issued an accounting standards update (“ASU”) which amends Accounting Standards Codification (“ASC”) 326-20 to provide a practical expedient and an accounting policy election related to the estimation of expected credit losses for current accounts receivable and current contract assets that arise from transactions accounted for under ASC 606. An entity is required to disclose whether it has elected to use the practical expedient and, if so, whether it has also applied the accounting policy election. The Company adopted this pronouncement effective April 1, 2026 and elected to use the practical expedient. The Company’s adoption did not have a material impact on the Company’s Condensed Consolidated Financial Statements. Except for the pronouncements described above, there have been no new accounting pronouncements issued or adopted since the filing of the Fiscal 2026 Form 10-K that have significance, or potential significance, to the Consolidated Financial Statements.
Leases	Nature of the Company’s Leases - The Company has operating and finance leases for plants, yards, corporate offices, tractors, trailers and other equipment. The Company’s leases have remaining terms of less than one year to 11 years. A portion of the Company’s yard leases include an option to extend the leases for up to five years. The Company has included renewal options which are reasonably certain to be exercised in its right-of-use assets and lease liabilities.
