Income Tax Disclosure [Abstract] |
Income Tax Disclosure [Text Block] | Note 12. Income Taxes The Company’s income tax provision was approximately $4.5 million and $3.8 million for the three months ended July 31, 2024 and 2023, respectively. The Company’s income tax provision was approximately $8.2 million and $5.8 million for the six months ended July 31, 2024 and 2023, respectively. 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. 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, 2022 related to refined coal production tax credits pursuant to IRC Section 45 and research and experimentation credits claimed during those years. 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, |
|  | 2024 |  |  | 2023 |
Unrecognized tax benefits, beginning of period |  | $ | 18,965 |  |  | $ | 19,088 |
Changes for prior years’ tax positions |  |  | 14 |  |  |  | 3 |
Changes for current year tax positions |  |  | - |  |  |  | - |
Unrecognized tax benefits, end of period |  | $ | 18,979 |  |  | $ | 19,091 |
At July 31, 2024 and January 31, 2024, approximately $16.4 million of the unrecognized tax benefits balance was recorded on the accompanying Consolidated Balance Sheets within “Other assets”, $0.6 million was recorded within “Other long-term liabilities”, and $2.0 million was recorded within “Refundable income taxes”.
