INCOME TAXES
The Company’s worldwide effective tax rate for the three months ended March 31, 2016 and 2015 was 21.0% and 19.3%, respectively. The main factor that caused an increase in our worldwide effective tax rate was the change in the geographic mix of the current year earnings towards countries with higher statutory rates such as the U.S., Germany, Canada and India.  
For the three months ended March 31, 2016 and 2015, the difference between our effective income tax rates and the U.S. federal statutory rate is primarily due to the effect of the Belarus tax holiday and earnings taxed in countries that have lower rates than the United States.
