Note 8. Income Taxes

Our effective tax rates for the three months ended March 31, 2017 and 2016 were less than 2%. The effective tax rates differ from the statutory rate primarily as a result of not recognizing a deferred tax asset for U.S. losses due to having a full valuation allowance against U.S. deferred tax assets.
