Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company evaluates its deferred tax assets quarterly to determine if valuation allowances are required. In assessing the realizability of deferred tax assets, the Company considers both positive and negative evidence in determining whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The Company had a valuation allowance of $0.1 million against its deferred tax assets related to certain state tax jurisdictions as of June 30, 2017 and December 31, 2016. To the extent the Company generates future tax net operating losses, the Company may be required to increase the valuation allowance on deferred tax assets, which may unfavorably impact the effective tax rate. The Company has no material uncertain tax positions as of June 30, 2017 and December 31, 2016. For the three and six months ended June 30, 2017, the Company’s effective tax rate was 34.8% and 32.7%, respectively, which varied from the federal statutory rate of 35% primarily due to excess tax windfall benefits from stock compensation and a permanent domestic manufacturing deduction under Internal Revenue Code Section 199 (the “Manufacturing Deduction”). For the three and six months ended June 30, 2016, the effective tax rate was 33.1% and 30.6%, respectively, which varied from the federal statutory rate of 35% primarily due to the excess tax windfall benefit from stock compensation and the Manufacturing Deduction.
