12. Income Taxes

          The following table presents the Company’s income tax expense (benefit):

          The Company’s provision (benefit) for income tax was a benefit of $1.6 million and an expense of $3.4 million for the three months ended June 30, 2013 and July 1, 2012, respectively. The Company’s income tax expense was $0.8 million and $6.8 million for the six months ended June 30, 2013 and July 1, 2012, respectively.

          The tax (benefit)/expense for the three months and tax expense for the six months ended June 30, 2013 was primarily attributable to pre-tax income in foreign jurisdictions and withholding taxes related to Samsung licensing revenue offset by the release of reserves for uncertain tax positions in foreign locations.

          The tax expense for the three and six months ended July 1, 2012 was primarily attributable to pre-tax income in foreign jurisdictions, withholding taxes related to Samsung licensing revenue and the impact from the sale of land and building in Kuala Lumpur offset by the release of reserves for uncertain tax positions in foreign locations.

           As of December 30, 2012, the Company had U.S. federal and state net operating loss carry forwards of approximately $992.2 million and $218.8 million, respectively. Approximately $490.6 million of the federal net operating loss carry forwards are subject to an annual limitation of $27.2 million. The federal and state net operating losses, if not utilized, expire from 2016 to 2031. The Company also has U.S. federal credit carryovers of $1.0 million which expire from 2020 to 2021. The Company also has state tax credits of $17.6 million, which includes California state tax credits of $16.8 million that can be carried forward indefinitely.

           If the Company were to undergo an “ownership change” for purposes of Section 382 of the Internal Revenue Code of 1986, as amended, its ability to utilize its federal net operating loss carry forwards could be limited under certain provisions of the Internal Revenue Code. As a result, the Company could incur greater tax liabilities than it would in the absence of such a limitation and any incurred liabilities could materially adversely affect the Company’s results of operations and financial condition.
