Income Tax Disclosure [Abstract] |
Income Taxes | Income Taxes The 2017 estimated annual effective tax rate is expected to be approximately 31.9%. Due to the adoption of ASU 2016-09, the tax effects of option exercises or vested awards should be treated as discrete items in the reporting period in which they occur, and therefore cannot be considered in the calculation of the estimated annual effective tax rate. Excluding the impact of ASU 2016-09, the estimated annual effective tax rate would be 35.6%. Differences between the effective tax rate and the applicable U.S. federal statutory rate arise primarily from the effect of state and local income taxes, share-based compensation and tax credits available to the Company. The actual 2017 effective tax rate will likely vary from the estimate depending on the availability of tax credits and the exercises of stock options and vesting of share-based awards. The Company accounts for income taxes using the asset and liability method, which results in recognizing income tax expense based on the amount of income taxes payable or refundable for the current year. Additionally, the Company regularly evaluates the tax positions taken or expected to be taken resulting from financial statement recognition of certain items. Based on the evaluation, there are no significant uncertain tax positions requiring recognition in the Company’s financial statements. The evaluation was performed for the tax years ended December 31, 2013 through 2016 (with regard to U.S. federal income tax returns) and December 31, 2012 through 2016 (with regard to various state and local income tax returns), the tax years which remain subject to examination by major tax jurisdictions as of September 30, 2017. The Company may from time to time be assessed interest or penalties by taxing jurisdictions, although any such assessments historically have been minimal and immaterial to its financial results. When the Company has received an assessment for interest and/or penalties, it will be classified in the financial statements as selling, general and administrative expense. In addition, any interest or penalties relating to recognized uncertain tax positions would also be recorded in selling, general and administrative expense.
