Income Tax Disclosure [Abstract]
Income Taxes	3. INCOME TAXES Our effective tax rate decreased from 34.0%, excluding the tax impact of the bargain purchase gain, in the nine months ended September 30, 2016, to 23.1% in the nine months ended September 30, 2017. The decrease in the effective tax rate between the periods is primarily attributable to additional research and development tax credits being recognized in the current quarter, an increase in stock option exercises and a greater mix of international income.
