Income Taxes | Note 3—Income Taxes At the end of each interim reporting period, we estimate the effective income tax rate expected to be applicable for the full year. This estimate is used to determine the income tax provision or benefit on a year-to-date basis and may change in subsequent interim periods. Our effective tax rate for the three months ended March 31, 2014 was a benefit of 2.0% compared to a benefit of 48.2% during the three months ended March 31, 2013. A tax benefit for each period was provided to the extent of future reversals of taxable temporary differences which relate primarily to tax deductible intangibles. Our effective tax rate for 2014 differed from the expected net operating loss carry forward benefit at the U.S. federal statutory rate of 35% primarily because of the inability to recognize such benefit due to uncertainties relating to future taxable income in terms of both its timing and its sufficiency, which would enable us to realize the federal carry forward benefit. The effective tax rate was also impacted because we did not provide a tax provision on the gain from the settlement of the contingent consideration related to the Synos acquisition. Our effective tax rate for 2013 differed from the U.S. federal statutory rate as a result of the jurisdictional mix of earnings in our foreign locations, an income tax benefit related to the generation of current year research and development tax credits, and legislation enacted in the first quarter of 2013 which extended the Federal Research and Development Credit for both the 2012 and 2013 tax years.
