Note 7 - Income Taxes
Income tax expense was $10.0 thousand and $11.0 thousand for the three months ended March 31, 2016 and 2015, respectively. Our effective tax rate was 1.7% and (1.8%) for the three months ended March 31, 2016 and 2015, respectively. Our effective tax rates differed from the U.S. statutory corporate tax rate of 35.0% primarily because of the mix of pre-tax income or loss earned in certain jurisdictions and the change in our valuation allowance.
We record a valuation allowance when it is more likely than not that some portion, or all, of the deferred tax assets will not be realized. As of March 31, 2016 and December 31, 2015, a valuation allowance of $6.7 million and $7.2 million, respectively, has been provided against net operating loss carryforwards and other deferred tax assets. We decreased our valuation allowance by $0.5 million and $0.4 million for the three months ended March 31, 2016 and 2015, respectively.
As of March 31, 2016 and December 31, 2015, we had total unrecognized tax benefits of $1.7 million, related to foreign and domestic tax positions. Of this amount, the Company estimates that $0.1 million, of the unrecognized tax benefits, if recognized, would impact the effective tax rate. A substantial portion of our liability for uncertain tax benefits is recorded as a reduction of net operating losses and tax credit carryforwards.
During the three months ended March 31, 2016 and 2015, we had no material changes in uncertain tax positions. We record interest and penalties related to unrecognized tax benefits within the provision for income taxes. We believe that no current tax positions that have resulted in unrecognized tax benefits will significantly increase or decrease within one year. We file income tax returns in the U.S. federal jurisdiction and in various state and foreign jurisdictions.
