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 2011.

For the three and nine months ended September 30, 2019 and 2018, 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 nine months ended September 30, 2019 was 25.1% compared to a rate of 24.9% for the same period in 2018. The higher effective tax rate for the nine months ended September 30, 2019 was primarily the result of a larger portion of executive compensation exceeding the IRS code section 162M limit, which makes it not deductible for income tax purposes in 2019 and a $300 Tennessee state job tax credit in
the prior year. This increase was partly offset by increased stock based compensation vesting when compared to the same period in 2018, which was impacted by forfeited performance shares.
