Income Taxes	16.Income Taxes The Company’s effective tax rate, as calculated by dividing income tax expense by income before income taxes, was 34.8% for the first three quarters of 2017 and 35.6% for the first three quarters of 2016. The decrease in the effective tax rate was primarily driven by a reduction in the valuation allowance resulting from the Company’s assessment of its ability to use certain loss carryforwards and a reduction to the Company’s uncertain tax positions resulting from the expiration of the statute of limitations. The Company’s effective tax rate, as calculated by dividing income tax expense by income before income taxes minus net income attributable to noncontrolling interest, was 38.8% for the first three quarters of 2017 and 39.4% for the first three quarters of 2016. The Company had uncertain tax positions, including accrued interest, of $1.8 million on October 1, 2017 and $2.9 million on January 1, 2017, all of which would affect the Company’s effective tax rate if recognized. While it is expected the amount of uncertain tax positions may change in the next 12 months, the Company does not expect such change would have a significant impact on the consolidated condensed financial statements. Prior tax years beginning in year 2002 remain open to examination by the Internal Revenue Service, and various tax years beginning in year 1998 remain open to examination by certain state tax jurisdictions due to loss carryforwards.
