Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The provision for income taxes was $28.4 million for the three months ended June 30, 2015 compared to $26.2 million in the three months ended June 30, 2014. The effective income tax rate was 35.7% for the three months ended June 30, 2015 and 33.1% for the same period in 2014. The quarter-over-quarter increase in the effective income tax rate was primarily due to a change in the estimated mix of pretax income by jurisdiction as well as increases in unrecognized tax benefits. The provision for income taxes was $44.2 million for the six months ended June 30, 2015 compared to $45.2 million in the six months ended June 30, 2014. The effective income tax rate was 35.8% for the six months ended June 30, 2015 and 33.2% for the same period in 2014. The increase in the effective income tax rate was primarily due to a change in the estimated mix of pre-tax income by jurisdiction as well as increases in unrecognized tax benefits compared to the same period in 2014. As of June 30, 2015 and December 31, 2014, the Company had gross unrecognized tax benefits of $21.7 million and $20.6 million, respectively. It is reasonably possible that gross unrecognized tax benefits will decrease by approximately $3.8 million within the next 12 months due to the anticipated closure of audits and the expiration of certain statutes of limitation. These unrecognized tax benefits relate primarily to the utilization of tax attributes, as well as certain other unrecognized tax positions, each of which are individually insignificant.
