Income Taxes	10. Income Taxes Provision (benefit) for income taxes includes both domestic and foreign income taxes at the applicable tax rates adjusted for non-deductible expenses, research and development tax credits and other permanent differences. Income tax expense (benefit) was $0.2 million and $(0.6) million for the three months ended April 3, 2021 and April 4, 2020, resulting in effective tax rates of 1.5% and (35.4)%, respectively. The higher provision for income taxes for the three months ended April 3, 2021 was primarily due to higher profits, partially offset by the amount of income earned in foreign jurisdictions where the tax rate may be lower than the federal statutory rate, as well as permanent items including excess tax benefits from stock-based awards and the federal research and development credit. The benefit from income taxes for the three months ended April 4, 2020 was primarily due to lower profits relative to the amount of income earned in foreign jurisdictions where the tax rate may be lower than the federal statutory rate, as well as the increased impact of permanent items including the federal research and development credit, the tax effects of non-deductible stock-based compensation, global intangible low-tax income (“GILTI”) and excess tax benefits from stock-based awards. Uncertain Tax Positions As of April 3, 2021, the Company had gross unrecognized tax benefits, inclusive of interest, of $3.2 million, of which $2.5 million would affect the effective tax rate if recognized. During the three months ended April 3, 2021, the Company did not release any of its unrecognized tax benefits. The Company recognizes interest and penalties related to unrecognized tax benefits in the provision (benefit) for income taxes. These amounts were not material for any of the periods presented. Following the completion of the Norwegian Tax Administration (“NTA”) examination of the Company’s Norwegian subsidiary for income tax matters relating to fiscal years 2013 - 2016, the Company received an assessment from the NTA in December 2017 concerning an adjustment to its 2013 taxable income related to the pricing of an intercompany transaction. The Company is currently appealing the assessment. The adjustment to the pricing of the intercompany transaction results in approximately 141.3 million Norwegian kroner, or $16.6 million additional Norwegian income tax. The Company disagrees with the NTA’s assessment and believes the Company’s position on this matter is more likely than not to be sustained. The Company plans to exhaust all available administrative remedies, and if unable to resolve this matter through administrative remedies with the NTA, the Company plans to pursue judicial remedies. 10. Income Taxes (Continued) The Company believes that it has accrued adequate reserves related to all matters contained in tax periods open to examination. Should the Company experience an unfavorable outcome in the NTA matter, however, such an outcome could have a material impact on its financial statements. Tax years 2015 through 2021 remain open to examination by the major taxing jurisdictions in which the Company operates. The Company is not currently under audit in any major taxing jurisdiction. The Company does not expect material changes to its gross unrecognized tax benefits in the next 12 months.
