Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES The Company’s estimated annual effective tax rate is 22.3% before discrete items. For the nine months ended September 30, 2018, discrete items resulted in a tax benefit of $0.6 million, consisting of a stock compensation windfall of $0.1 million and a non-recurring benefit of $0.5 million related to re-measurement of deferred taxes resulting from state tax law change. Due to the timing of the enactment and the complexity involved in applying the provisions of the Tax Cuts and Jobs Act of 2017 (the "Act"), the Company calculated its best estimate of the impact of the Act in its 2017 year end income tax provision in accordance with its understanding of the Act and guidance available as of the date of its Annual Report on Form 10-K for fiscal year 2017 and as a result had recorded a provisional $9.2 million reduction in income tax expense in the fourth quarter of 2017. No adjustment was made to the provisional amount as a result of additional information obtained for the nine months ended September 30, 2018. The Company is subject to audit examinations at federal, state and local levels by tax authorities in those jurisdictions. In addition, the Canadian operations are subject to audit examinations at federal and provincial levels by tax authorities in those jurisdictions. The tax matters challenged by the tax authorities are typically complex; therefore, the ultimate outcome of any challenges would be subject to uncertainty. The Company has not identified any issues that did not meet the recognition threshold or would be impacted by the measurement provisions of the uncertain tax position guidance.
