Commitments and Contingencies Disclosure [Abstract] |
Commitments and Contingencies Disclosure [Text Block] | Note 13. Commitments and Contingencies The Company may be involved in various legal actions arising in the normal course of business, from time to time. After taking into consideration legal counsels’ evaluations of any such action(s), management is of the opinion that their outcome will not have a material adverse effect on the Company’s Consolidated Condensed Financial Statements. One Earth and NuGen have combined forward purchase contracts for approximately 12.3 million bushels of corn, the principal raw material for their ethanol plants, and they have combined forward purchase contracts for approximately 1.1 million MmBtu (million British thermal unit) of natural gas. One Earth and NuGen have combined sales commitments for approximately 36.8 million gallons of ethanol, approximately 82,000 tons of distillers grains and approximately 8.9 million pounds of non-food grade corn oil. The refined coal entity had various agreements (site license, operating agreements, etc.) containing payment terms based upon production of refined coal under which the Company was required to pay various fees. As production ceased in November 2021, there were no fees paid in fiscal year 2022. These fees totaled approximately $2.2 million and approximately $3.1 million for the three and six months ended July 31, 2021, respectively.
