Condensed Financial Information Disclosure [Abstract] |
Condensed Financial Information of Parent Company Only Disclosure [Text Block] | Note 1. Consolidated Condensed Financial Statements References to the Company – References to “REX” or the “Company” in the consolidated condensed financial statements and in these notes to the consolidated condensed financial statements refer to REX American Resources Corporation, a Delaware corporation, and its majority and wholly owned subsidiaries. The consolidated condensed financial statements included in this report have been prepared by the Company, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission and include, in the opinion of management, all adjustments necessary to state fairly the information set forth therein. Any such adjustments were of a normal recurring nature. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been omitted pursuant to such rules and regulations, although the Company believes that the disclosures are adequate to make the information presented not misleading. Financial information as of January 31, 2021 included in these financial statements has been derived from the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended January 31, 2021 (fiscal year 2020). It is suggested that these unaudited consolidated condensed financial statements be read in conjunction with the consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the year ended January 31, 2021. The results of operations for the interim periods are not necessarily indicative of the results to be expected for the year. Basis of Consolidation – The consolidated condensed financial statements in this report include the operating results and financial position of the Company. All intercompany balances and transactions have been eliminated. The Company consolidates the results of its four majority owned subsidiaries. The Company includes the results of operations of One Earth Energy, LLC (“One Earth”) in its Consolidated Condensed Statements of Operations on a delayed basis of one month as One Earth has a fiscal year end of December 31. On November 18, 2021, the Company ceased operation of its refined coal business as tax credits could no longer be earned on its operations. Beginning in the third quarter of fiscal year 2021, the results of the operation of the refined coal business were recognized in discontinued operations. Prior period amounts have been reclassified to conform with discontinued operations reporting. Nature of Operations – Beginning in the third quarter of fiscal year 2021, the Company now has one reportable segment, ethanol and by-products. Within the ethanol and by-products segment, the Company has equity investments in three ethanol limited liability companies, two of which are majority ownership interests. Prior period amounts have been reclassified to conform to the current segment reporting.
