The Company’s tax expense decreased from $8.6 million for the three months ended September 25, 2011 to $2.8 million for the three months ended September 30, 2012. The decrease was primarily related to the amount of withholding taxes on licensing revenue from Samsung. The tax expense decreased from $15.4 million for the nine months ended September 25, 2011 to $9.6 million for the nine months ended September 30, 2012. The decrease was primarily attributable to a release of reserves for uncertain tax positions in foreign locations and the amount of withholding taxes on licensing revenue from Samsung, offset by the impact from the sale of land and building in Kuala Lumpur, Malaysia.

As of September 30, 2012, all of the Company's U.S. deferred tax assets, net of deferred tax liabilities, continue to be subject to a full valuation allowance. The valuation allowance is based on the Company's assessment that it is more likely than not that the deferred tax assets will not be realizable in the foreseeable future.

As of December 25, 2011, the Company had U.S. federal and state net operating loss carry forwards of approximately $1.0 billion and $208.0 million, respectively. Approximately $533.6 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 between 2016 and 2031.

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.
