Notes
Income Taxes	5. The Company’s effective tax rates were 21.0% and 32.9% for the third quarter of 2018 and 2017, respectively, and 22.4% and 32.6% for the nine months ended September 30, 2018 and 2017, respectively. The lower rate in 2018 is due to the enactment of the Tax Cuts and Jobs Act in December 2017 that reduced the maximum federal corporate tax rate from 35% to 21% beginning in 2018. The effective rate was lower than the U.S. federal statutory rate in 2017 primarily due to the Domestic Production Activities Deduction allowed under Internal Revenue Code Section 199. The Company’s federal income tax returns for the 2015, 2016 and 2017 tax years are subject to examination by the Internal Revenue Service (“IRS”). While it may be possible that a reduction could occur with respect to the Company’s unrecognized tax benefits as an outcome of an IRS examination, management does not anticipate any adjustments that would result in a material change to the results of operations or financial condition of the Company. No statutes have been extended on any of the Company’s federal income tax filings. The statute of limitations on the Company’s 2015, 2016 and 2017 federal income tax returns will expire on September 15, 2019, 2020 and 2021, respectively. The Company’s state income tax returns for the 2015 through 2017 tax years remain subject to examination by various state authorities with the latest closing period on October 31, 2021. The Company is currently not under examination by any state authority for income tax purposes and no statutes for state income tax filings have been extended.
