Income Tax Disclosure [Abstract] |
Income Taxes | Income Taxes The Company or one of its subsidiaries files income tax returns in the U.S. federal jurisdiction, various states and Canada. With a few exceptions, the Company is no longer subject to U.S. federal, state and local, or Canadian examinations by tax authorities for years before 2012. For the three months ended March 31, 2020 and 2019, the effective income tax rates varied from the statutory federal income tax rate of 21.0%, primarily as a result of the effect of state income taxes, net of the federal benefit, and permanent differences between book and tax net income. The combined federal and state effective tax rate for the three months ended March 31, 2020 was 22.8% compared to a rate of 23.8% for the same period in 2019. The lower effective tax rate for the three months ended March 31, 2020 was primarily the result of a refund for Tennessee tax credits and increased stock based compensation vesting as a percentage of income before income taxes. This was partially offset by increased executive compensation as a percentage of income before income taxes, which was not deductible for income tax purposes.
