Income Tax Disclosure [Abstract]
Income Taxes	3. INCOME TAXES Our effective tax rate decreased from 37.9% in the six months ended June 30, 2016 to 27.3% in the six months ended June 30, 2017. The decrease in the effective tax rate between the two periods is primarily attributable to a 6.3% effective rate reduction due to a greater mix of international revenues and a 3.2% effective rate reduction for a provision-to-return adjustment related to the assignment of research and development expenditures to specific company engineering locations.
