Income Tax Disclosure [Abstract] |
Income Taxes | Income Taxes Income tax provisions for the Company's interim periods are based on the effective income tax rate expected to be applicable for the full year. The Company's effective tax rate for the three months ended December 31, 2016 was 29.3%, compared to 25.3% for the three months ended December 31, 2015. The fiscal 2016 first quarter effective tax rate was lower than the fiscal 2017 first quarter tax rate primarily as a result of the retroactive reinstatement of the U.S. research and experimentation tax credit during fiscal 2016. The difference between the Company's fiscal 2017 first quarter effective tax rate and the Federal statutory rate of 35.0% primarily reflected lower foreign income taxes, offset by the impact of state taxes. The Company had unrecognized tax benefits (excluding penalties and interest) of $13,698 and $13,820 on December 31, 2016 and September 30, 2016, respectively. The amount of unrecognized tax benefits that, if recognized, would impact the effective tax rate were $6,541 and $6,663 at December 31, 2016 and September 30, 2016, respectively. The Company classifies interest and penalties on tax uncertainties as a component of the provision for income taxes. Total penalties and interest accrued were $2,225 and $2,088 at December 31, 2016 and September 30, 2016, respectively. These accruals may potentially be applicable in the event of an unfavorable outcome of uncertain tax positions. The Company is currently under examination in several tax jurisdictions and remains subject to examination until the statute of limitations expires for those tax jurisdictions. As of December 31, 2016, the tax years that remain subject to examination by major jurisdiction generally are:
United States – Federal | 2013 and forward
United States – State | 2012 and forward
Canada | 2012 and forward
Germany | 2009 and forward
United Kingdom | 2014 and forward
Australia | 2012 and forward
Singapore | 2010 and forward
