Income Taxes	13. Income Taxes Provision for income taxes includes both domestic and foreign income taxes at the applicable statutory rates adjusted for non-deductible expenses, research and development tax credits and other permanent differences. Income tax expense was $0.7 million and $1.5 million for the three months ended April 4, 2015 and March 29, 2014, resulting in effective tax rates of 9.7% and 15.3%, respectively. The effective tax rate for the three months ended April 4, 2015 decreased from the prior period, primarily due to an increase in the foreign tax rate benefit in the current period resulting from the completion of payments related to an intercompany licensing transaction. This decrease in the effective tax rate was partially offset by the release during the prior period of unrecognized tax benefits related to an uncertain tax position that was closed by statute. At April 4, 2015, the Company had gross unrecognized tax benefits of $3.8 million, all of which would affect the effective tax rate if recognized. The Company recognizes interest and penalties related to unrecognized tax benefits in the provision for income taxes. The Company believes it is reasonably possible that the gross unrecognized tax benefits will decrease by approximately $0.6 million in the next 12 months due to the lapse of the statute of limitations applicable to a tax deduction claimed on a prior year foreign tax return. The tax years 2010 through 2015 remain open to examination by the major taxing jurisdictions to which the Company is subject. The Company is not currently under audit in any major taxing jurisdiction.
