Income Tax Disclosure [Abstract] |
Income Tax Disclosure [Text Block] | Note 11. Income Taxes The Company determined that small changes in estimated “ordinary” income would result in significant changes in the estimated annual effective tax rate. Thus, the Company used a discrete effective tax rate method to calculate the provision or benefit for income taxes for the three and six months ended July 31, 2021 and 2020. The Company’s income tax benefit was approximately $3.7 million and approximately $4.0 million for the three months ended July 31, 2021 and 2020, respectively. The Company’s income tax benefit was approximately $3.6 million and approximately $9.4 million for the six months ended July 31, 2021 and 2020, respectively. We had a higher benefit in the prior year periods based upon pre-tax losses for those periods versus pre-tax income in the current periods. The benefit is also largely impacted by the level of tax credits generated from the refined coal operation. Through its refined coal operation, the Company earns production tax credits pursuant to IRC Section 45. The credits can be used to reduce future income tax liabilities for up to 20 years. In addition, the Company’s income tax benefit for the first six months of fiscal year 2020 includes approximately $1.8 million related to the lengthening of a net operating loss carryback allowed by the CARES Act. The Company assessed all available positive and negative evidence to determine whether it expects sufficient future taxable income will be generated to allow for the realization of existing federal deferred tax assets. For the three year period ended July 31, 2021, the Company has a cumulative pre-tax book loss on a comprehensive basis, including the impact of an operation that has historically produced pre-tax book losses, but after tax net income. The Company expects that this entity will cease operations by November 18, 2021. There is sufficient objectively verifiable income for management to conclude that it is more likely than not that the Company will utilize available federal deferred tax assets prior to their expiration. The Company files a U.S. federal income tax return and various state income tax returns. In general, the Company is no longer subject to U.S. federal, state or local income tax examinations by tax authorities for years ended January 31, 2014 and prior. The Company is currently undergoing a federal income tax examination for the years ended January 31, 2015 through January 31, 2020. On a quarterly and annual basis, the Company accrues for the effects of open uncertain tax positions and the related potential penalties and interest. It is reasonably possible that the amount of the unrecognized tax benefit with respect to certain unrecognized tax positions will increase or decrease during the next 12 months; however, the Company does not expect the change to have a material effect on results of operations or financial position. A reconciliation of the beginning and ending amount of unrecognized tax benefits, including interest and penalties, is as follows (amounts in thousands):
|  | Six Months Ended July 31, |
|  | 2021 |  |  | 2020 |
Unrecognized tax benefits, beginning of period |  | $ | 8,400 |  |  | $ | 7,370 |
Changes for prior years’ tax positions |  |  | 10 |  |  |  | (53) |
Changes for current year tax positions |  |  | 275 |  |  |  | - |
Unrecognized tax benefits, end of period |  | $ | 8,685 |  |  | $ | 7,317 |
