Income Taxes [Abstract] |
Income Taxes | 12. Income Taxes The Tax Cuts and Jobs Act (the “2017 Act”) was signed into law on December 22, 2017. The 2017 Act includes a broad range of tax reform legislation affecting businesses, including lowering corporate tax rates, among other provisions. Under accounting principles generally accepted in the United States of America, changes in tax rates and tax law are accounted for in the period of enactment. The Company recognized the income tax effects of the 2017 Act in accordance with Staff Accounting Bulletin No. 118, which provides SEC staff guidance for the application of ASC Topic 740, Income Taxes. The 2017 Act reduced the federal corporate tax rate from 35% to 21% for tax years beginning after December 31, 2017. ASC 740 requires deferred tax assets and liabilities to be valued using enacted tax rates in effect in the year in which the differences are expected to reverse. Thus, the Company revalued its federal deferred taxes based upon the new 21% tax rate as of December 31, 2017. The 2017 Act also allows for immediate full expensing for property placed in service after September 27, 2017 and before January 1, 2023. The Company has made the election to accelerate these deductions for the year ended December 31, 2017 tax returns. At this time, it is uncertain which states will follow federal rules regarding accelerated depreciation, and therefore, the Company has not been able to make a reasonable estimate on the impact of deferred taxes related to state depreciation and continues to account for accelerated depreciation based on the provisions of the tax laws that were in effect prior to enactment. In addition, the 2017 Act places limitations on the deductibility of certain executive compensation awards in the future, although the Company’s existing awards remain eligible for deductibility pursuant to the 2017 Act. The Company is still analyzing the 2017 Act and refining its calculations, which could potentially impact the measurement of the Company’s tax balances. The Company had $0.3 million and $0.7 million of unrecognized tax benefits as of September 30, 2017 and 2018, respectively. Interest and penalties, including those related to uncertain tax positions, are included in the provision for income taxes in the unaudited condensed consolidated statements of income. The Company incurred no expense related to interest and penalties during the nine months ended September 30, 2017 and 2018, respectively. The Company paid $21.8 million and $10.9 million in income taxes during the nine months ended September 30, 2017 and 2018, respectively.
