Income Tax Disclosure [Abstract]
Income Taxes	fective tax rate was 33% for each of the three months ended March 31, 2016 and March 31, 2015. The difference in the effective rates for each period, compared to the statutory rate of 35%, is primarily attributable to the mix of pretax income in each year among domestic and foreign jurisdictions which are taxed at different rates. As of March 31, 2016, our gross liability for unrecognized tax benefits was $4.3 million. If fully recognized, these tax benefits would decrease our income tax expense by $4.3 million ($2.8 million, net of federal tax). During the three months ended March 31, 2016, we reduced our unrecognized tax benefit by $1.4 million based on a final determination ruling for a disputed state tax filing position. None of this amount was recognized in net income. We do not anticipate the recognition of tax benefits that were previously unrecognized within the next 12 months.
