Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For the three months ended March 31, 2017, we earned $21.8 million before taxes and provided for income taxes of $6.8 million resulting in an effective tax rate of 31.0%. The effective tax rate varied from the U.S. federal statutory rate for the three months ended March 31, 2017 primarily due to the net impact of foreign operations. For the three months ended March 31, 2016, we earned $56.0 million before taxes and provided for income taxes of $17.7 million resulting in an effective tax rate of 31.6%. The effective tax rate varied from the U.S. federal statutory rate for the three months ended March 31, 2016 primarily due to the net impact of foreign operations. As of March 31, 2017, the amount of unrecognized tax benefits increased by $3.4 million from December 31, 2016. With limited exception, we are no longer subject to U.S. federal income tax audits for years through 2014, state and local income tax audits for years through 2010 or non-U.S. income tax audits for years through 2009. We are currently under examination for various years in Austria, Germany, India, Italy, Singapore, the U.S. and Venezuela. It is reasonably possible that within the next 12 months the effective tax rate will be impacted by the resolution of some or all of the matters audited by various taxing authorities. It is also reasonably possible that we will have the statute of limitations close in various taxing jurisdictions within the next 12 months. As such, we estimate we could record a reduction in our tax expense of approximately $8 million within the next 12 months.
