(1) | The Tax Cuts and Jobs Act, enacted in December 2017, allowed first year bonus depreciation at 100% for assets placed into service between September 27, 2017 and January 1, 2023. Due to a decrease in the purchase of assets eligible for 100% depreciation, the deferred tax expense related to the tax depreciation expense in excess of book depreciation decreased over the two-year period from 2020 through 2021 but increased in 2022.

​ Income taxes paid, excluding income tax refunds, totaled $148.7 million, $77.5 million, and $28.6 million in 2022, 2021, and 2020, respectively. Income tax refunds totaled $42.3 million, $19.4 million, and $13.3 million in 2022, 2021, and 2020, respectively. ​ Under Accounting Standards Codification Topic 718, Compensation – Stock Compensation, the Company may experience volatility in its income tax provision as a result of recording all excess tax benefits and tax deficiencies in the income statement upon settlement of awards, which occurs primarily during the second quarter of each year. The 2022 and 2021 tax rates reflect a tax benefit of 2.1% and 2.8%, respectively, and the 2020 tax rate reflects tax expense of 0.5%, for settlement of stock awards. The tax benefit of dividends on share-based payment awards was less than $0.1 million for each of the years 2022, 2021, and 2020. ​ At December 31, 2022, the Company had gross federal net operating loss carryforwards of $0.8 million. Due to taxable income, there is no need for a valuation allowance on these amounts at December 31, 2022 or 2021, and the related valuation allowance of $0.1 million was removed at December 31, 2021. At December 31, 2022, the Company had total gross state net operating losses of $9.9 million. Gross state net operating losses of $1.0 million are from the acquisition of Panther and relate to periods ending on or prior to June 15, 2012. State carryforward periods for the remaining Panther net operating losses vary from 10 to 15 years. Gross state net operating losses of $7.3 million are for subsidiaries that have had taxable losses for three or more prior tax years or have other nexus issues that reduce the likelihood of the utilization of the losses. These net operating loss carryforwards have been fully reserved with valuation allowances of $0.4 million and $1.1 million at December 31, 2022 and 2021, respectively. Additional valuation allowances of $0.2 million related to state research and development tax credits were reserved at December 31, 2022 and 2021, and less than $0.1 million related to state interest expense carryforwards was reserved at December 31, 2022 and 2021. ​ As the Canadian tax rate is now higher than the U.S. tax rate, it is unlikely that foreign tax credit carryforwards will be useable, as U.S. taxes will be paid at a lower rate than the tax rates in Canada. Thus, the foreign tax credit carryover is fully reserved, resulting in valuation allowances of $1.0 million and $0.8 million at December 31, 2022 and 2021, respectively. ​ Consolidated federal income tax returns filed for tax years through 2018 are closed by the applicable statute of limitations. The Company is not under examination by any federal or foreign taxing authorities at December 31, 2022. The Company is under examination by one state taxing authority at December 31, 2022. ​ At December 31, 2022 and 2021, there was a reserve for uncertain tax positions of $0.9 million related to credits taken on federal returns. ​ For 2022, 2021, and 2020, interest paid or accrued related to foreign and state income taxes was immaterial.
