Income taxes
The Company's effective tax rate was 31.2% for the three months ended March 31, 2016 and 27.0% for the three months ended March 31, 2015. The tax rate is higher than the comparable period in 2015 primarily due to the proportion of losses being generated in the United States, which are benefited at a higher statutory tax rate, as compared to earnings being generated outside the United States in jurisdictions subject to lower tax rates. The effective tax rate can vary from period to period depending on the Company's relative mix of U.S. and non-U.S. earnings.
