Income Taxes	Income Taxes The effective tax rate for the quarter to date period ended December 31, 2016 was 33.4% compared to 25.9% for the comparable period in the prior year. The higher effective tax rate in the current period is due primarily to the difference in discrete tax items recognized in each period. The current period included $1.7 million of period tax expenses related principally to the revaluation of France deferred tax assets due to a France tax law change that reduced the future corporate income tax rate in France, partially offset by the impact of excess tax benefits due to the adoption of ASU 2016-09 discussed in Note 1. The comparable period in the prior year included period tax benefits of $1.7 million primarily due to the retroactive reinstatement of the research tax credit. Absent the period tax items, the current year rate would have been lower compared to prior year due primarily to the geographic mix of income, along with prior year losses incurred in select foreign jurisdictions for which no tax benefit could be recognized. In December 2016, the French parliament approved the Finance Act for 2017 and the Amended Finance Act for 2016 (the Finance Acts). The tax portion of the bill progressively reduces the corporate income tax rate from 33.3% to 28.0%. The Finance Acts were effective December 30, 2016. On December 18, 2015, President Obama signed into law a combined tax and government funding bill (H.R. 2029). The tax portion of the bill, the Protecting Americans from Tax Hikes Act (the PATH Act), extended and made permanent several lapsed business incentives that impact our business, including the extension of bonus depreciation as well as the retroactive and permanent extension of the research tax credit.
