Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company’s tax provision for interim periods is determined using an estimate of its annual effective income tax rate, adjusted for discrete items, if any, that are taken into account in the relevant period. Each quarter, the Company updates its estimated annual effective income tax rate, and if the estimated income tax rate changes, a cumulative adjustment is made. The effective income tax rates for the first nine months of 2016 and 2015 were 18.3% and 34.8%, respectively. The effective tax rate for 2016 is lower compared to 2015 due to the 2016 reversal of various income tax accruals totaling approximately $4.0 million relating to previous uncertain tax positions for which the statutes of limitations expired. The Company recognizes accrued interest and penalties related to uncertain tax positions in income tax expense. During the three- and nine-months ended September 30, 2016, the Company recorded an increase to unrecognized tax benefits of approximately $0.1 million and $0.2 million, respectively, related to prior year tax positions and accrued interest. It is reasonably possible that, within the next twelve months, the amount of gross unrecognized tax benefits could be reduced by approximately $1.3 million as a result of the closure of tax statutes related to existing uncertain tax positions.

The Company’s tax provision for interim periods is determined using an estimate of its annual effective income tax rate, adjusted for discrete items, if any, that are taken into account in the relevant period. Each quarter, the Company updates its estimated annual effective income tax rate, and if the estimated income tax rate changes, a cumulative adjustment is made.

The effective income tax rates for the first nine months of 2016 and 2015 were 18.3% and 34.8%, respectively. The effective tax rate for 2016 is lower compared to 2015 due to the 2016 reversal of various income tax accruals totaling approximately $4.0 million relating to previous uncertain tax positions for which the statutes of limitations expired. The Company recognizes accrued interest and penalties related to uncertain tax positions in income tax expense. During the three- and nine-months ended September 30, 2016, the Company recorded an increase to unrecognized tax benefits of approximately $0.1 million and $0.2 million, respectively, related to prior year tax positions and accrued interest. It is reasonably possible that, within the next twelve months, the amount of gross unrecognized tax benefits could be reduced by approximately $1.3 million as a result of the closure of tax statutes related to existing uncertain tax positions.
