Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Income tax expense for the quarter and year to date period ended September 30, 2016 was $2,316 and $9,758, respectively, for an effective tax rate for the quarter of 19.5 percent and for the year to date period of 29.9 percent. The effective tax rate differs from the 35 percent federal statutory rate on pretax income primarily due to the impact of the adoption of ASU No. 2016-09, a discrete event recognized on a prospective basis, resulting in a reduction to the rate of approximately 13.3 percentage points for the quarter and 4.8 percentage points for the year to date period (see below), the domestic production activities deduction, and state income taxes, including recent nexus and state tax credit planning activities, in particular, tax credits related to an expansion in Indiana related to the Company's Lawrenceburg facility, which are activities treated as ordinary income items and in the annual effective tax rate. The Company continues to evaluate all available positive and negative evidence to determine the likelihood of realization of the deferred tax assets. The Company elected to early-adopt ASU 2016-09, Compensation—Stock Compensation (Topic 718) Improvements to Employee Share-Based Payment Accounting in the quarter ended September 30, 2016. Due to the change in accounting principle required by the ASU adoption and the vesting of 128,500 shares of restricted stock during the quarter, the Company received a $1,571 tax-effected excess tax benefit from windfalls related to employee stock compensation that were recognized within income tax expense. Under prior guidance, windfalls were recorded to APIC and shortfalls were only recognized to the extent they exceeded the pool of windfall tax benefits. The tax-effected excess tax benefit was recorded in the quarter ended September 30, 2016, within Income tax expense on the Condensed Consolidated Statements of Income. The tax-effected excess tax benefit was also reflected in the Condensed Consolidated Statements of Cash Flows, along with other income tax cash flows, as a component of cash flows from operating activities on a prospective basis. ASU 2016-09 requires the tax effects of the transition event to be presented as a discrete item in the quarter the excess tax benefit was generated, which was the quarter ended September 30, 2016, for the Company. The effect of the ASU adoption related to excess tax benefits is on a prospective basis and, therefore, had no impact on prior years. There was no vesting of restricted stock or RSUs during the first and second quarters of 2016, so a recast of the prior 2016 interim financial statements was not required. Income tax expense for the quarter and year to date period ended September 30, 2015 was $1,042, which included the release of $1,908 of a valuation allowance, and $8,700, respectively. This resulted in an effective tax rate for the quarter of 13.3 percent and for the year to date period of 30.6 percent.
