Business Combination Disclosure [Text Block] | 3. BUSINESS COMBINATIONS On August 10, 2017, the Company, through a 95.35% owned subsidiary, purchased the entire ownership interest of an entity that owns a refined coal facility. The Company began operating its refined coal facility immediately after the acquisition. The Company expects that the revenues from the sale of refined coal produced in the facility will be subsidized by federal production tax credits through November 2021, subject to meeting qualified emissions reductions as governed by Section 45 of the Internal Revenue Code. The results of the Company’s refined coal operations (approximately $0.4 million of net sales and revenue and approximately $5.6 million of net income attributable to REX common shareholders, including the income tax benefit of estimated Section 45 credits to be earned) have been included in the consolidated financial statements subsequent to the acquisition date and are included in the Company’s refined coal segment. Pro forma net sales and revenue and net income attributable to REX common shareholders, had the acquisition occurred on February 1, 2016 would have been $453.8 million and $29.2 million, respectively for the year ended January 31, 2017. Basic and diluted earnings per share would have been $4.43 for the year ended January 31, 2017. Pro forma net sales and revenue and net income attributable to REX common shareholders, had the acquisition occurred on February 1, 2016 would have been $452.6 million and $40.4 million, respectively for the year ended January 31, 2018. Basic and diluted earnings per share would have been $6.12 for the year ended January 31, 2018. The purchase price was $12,049,000, which was paid in cash. The acquisition was recorded by allocating the total purchase price to the assets acquired, based on their estimated fair values at the acquisition date. The purchase price allocation is based on the preliminary results of a valuation analysis. The purchase price allocation is preliminary until the valuation analysis is completed. The income approach was used to determine the fair values of assets acquired. The following table summarizes the estimated fair values of the assets acquired at the acquisition date (amounts in thousands):
Inventory |  | $ | 49 |
Property, plant and equipment |  |  | 12,000 |
Total assets acquired and purchase price |  | $ | 12,049 |
Transaction costs totaled approximately $2.5 million during fiscal year 2017 and are included in selling, general and administrative expenses in the Consolidated Statement of Operations.
