Income Taxes	6 Months Ended
Jun. 30, 2016
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For the three- and six- months ended June 30, 2016, the Company recorded an income tax provision of $33.0 million and $17.3 million, respectively, yielding an effective tax rate of 39.6% and 35.7%, respectively. The effective tax rates differ from the U.S. statutory rate of 35% in the three and six-month period ended June 30, 2016 primarily due to higher income before income taxes, an increase in valuation allowances on state and foreign net operating losses for which tax benefits are not utilized, and changes in geographic earnings mix. For the three- and six-months ended June 30, 2015, the Company recorded an income tax benefit of $9.5 million and $23.2 million, respectively, yielding an effective tax rate of 10.8% and 19.9%. The effective tax rate differs from the U.S. statutory rate of 35% in the three- and six-month periods ended June 30, 2015 primarily due to an increase in the valuation allowance on state and foreign net operating losses for which tax benefits are not realized, the non-taxable holdback liability in the Last Mile logistics platform, a change in estimate of realization on prior tax positions, and changes in geographic earnings mix. In determining valuation allowances, an assessment of positive and negative evidence was performed regarding realization of the net deferred tax assets in accordance with ASC 740-10, “Accounting for Income Taxes.” This assessment included the evaluation of scheduled reversals of deferred tax liabilities, the availability of carry forwards and estimates of projected future taxable income. Based on the assessment, as of June 30, 2016, total valuation allowances of $71.6 million were recorded against deferred tax assets. Although realization is not assured, the Company has concluded that it is more likely than not that the remaining deferred tax assets will be realized and as such no valuation allowance has been provided on these assets. As of June 30, 2016, our foreign subsidiaries have undistributed earnings which could be subject to taxation if repatriated. Deferred tax liabilities have not been recorded for such earnings because it is management’s current intention to permanently reinvest such undistributed earnings in its non-U.S. subsidiaries. Due to the uncertainty caused by various methods in which such earnings could be repatriated, it is not practicable to estimate the actual amount of such deferred tax liabilities. The Company would consider and pursue appropriate alternatives to reduce any tax liability that would occur. If, in the future, undistributed earnings are repatriated to the U.S., or it is determined such earnings will be repatriated in the foreseeable future, deferred tax liabilities will be recorded accordingly.
