Income Taxes [Abstract]
Income Taxes	(12) Income Taxes For the quarters ended March 31, 2016 and 2015, the Company recorded a provision of $1,179 and a benefit of $6,943, respectively, resulting in effective tax rates of 7.1% of expense and 34.6% of benefit, respectively. The difference in the effective tax rates is primarily attributable to valuation allowances that were recorded in the fourth quarter of 2015 in the United States and certain foreign jurisdictions. The Company has not provided for any taxes on the unremitted earnings of its foreign subsidiaries, as the Company intends to permanently reinvest all such earnings outside of the U.S. We believe a calculation of the deferred tax liability associated with these undistributed earnings is impracticable. Tax years 1997 through 2015 remain subject to examination by the U.S. Internal Revenue Service, with most of the years open to examination due to the generation and utilization of net operating losses. The Company files income tax returns (which are open to examination beginning in the year shown in parentheses) in Australia (2011), Belgium (2013), Brazil (2011), China (2012), France (2013), Germany (2011), India (2012), Israel (2013), Italy (2012), Japan (2011), Korea (2011), Mexico (2011), Netherlands (2011), Switzerland (2011), the United Kingdom (2014) and Uruguay (2010).

(12) Income Taxes

For the quarters ended March 31, 2016 and 2015, the Company recorded a provision of $1,179 and a benefit of $6,943, respectively, resulting in effective tax rates of 7.1% of expense and 34.6% of benefit, respectively. The difference in the effective tax rates is primarily attributable to valuation allowances that were recorded in the fourth quarter of 2015 in the United States and certain foreign jurisdictions.

The Company has not provided for any taxes on the unremitted earnings of its foreign subsidiaries, as the Company intends to permanently reinvest all such earnings outside of the U.S. We believe a calculation of the deferred tax liability associated with these undistributed earnings is impracticable.

Tax years 1997 through 2015 remain subject to examination by the U.S. Internal Revenue Service, with most of the years open to examination due to the generation and utilization of net operating losses. The Company files income tax returns (which are open to examination beginning in the year shown in parentheses) in Australia (2011), Belgium (2013), Brazil (2011), China (2012), France (2013), Germany (2011), India (2012), Israel (2013), Italy (2012), Japan (2011), Korea (2011), Mexico (2011), Netherlands (2011), Switzerland (2011), the United Kingdom (2014) and Uruguay (2010).
