Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For the three months ended September 30, 2013, we earned $182.4 million before taxes and provided for income taxes of $55.9 million, resulting in an effective tax rate of 30.6%. For the nine months ended September 30, 2013, we earned $501.3 million before taxes and provided for income taxes of $155.0 million resulting in an effective tax rate of 30.9%. The effective tax rate varied from the U.S. federal statutory rate for the three months ended September 30, 2013 primarily due to the net impact of foreign operations. The effective tax rate varied from the U.S. federal statutory rate for the nine months ended September 30, 2013, primarily due to the net impact of foreign operations, partially offset by taxes incurred on the exit of our equity investment in the AIL joint venture discussed in Note 2. For the three months ended September 30, 2012, we earned $144.6 million before taxes and provided for income taxes of $37.8 million, resulting in an effective tax rate of 26.1%. For the nine months ended September 30, 2012, we earned $421.7 million before taxes and provided for income taxes of $112.9 million, resulting in an effective tax rate of 26.8%. The effective tax rate varied from the U.S. federal statutory rate for the three and nine months ended September 30, 2012 primarily due to the net impact of foreign operations and a net reduction of our reserve for uncertain tax positions due to the lapse of the statute of limitations in certain jurisdictions. As of September 30, 2013, the amount of unrecognized tax benefits increased by $0.5 million from December 31, 2012. With limited exception, we are no longer subject to U.S. federal income tax audits for years through 2011, state and local income tax audits for years through 2009 or non-U.S. income tax audits for years through 2007. We are currently under examination for various years in Austria, Canada, Finland, 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 $14 million within the next 12 months.
