Provision for Income Taxes

Note 10.     Provision for Income Taxes

For the three month periods ended March 31, 2015 and 2014, our effective tax rates were 22% and 32%, respectively. The difference between the U.S. federal statutory tax rate of 34% and our effective tax rates was due to non-U.S. based earnings being taxed at lower rates reducing the effective rates for the three month periods ended March 31, 2015 and 2014, by 10% and 2%, respectively. As of March 31, 2015, we do not foresee any significant changes to our unrecognized tax benefits within the next twelve months.
