Income Taxes
Note 8.  Income Taxes

As of January 28, 2012, we had approximately $360 of unrecognized tax benefits that would affect our effective tax rate if recognized.  We recognize interest and penalties related to income tax matters in income tax expense.  We do not expect our unrecognized tax benefits to change significantly over the next 12 months.
 
We are subject to U.S. Federal income tax as well as income taxes of multiple state jurisdictions.  As a result of the completion of exams by the Internal Revenue Service on prior years and the expiration of statutes of limitations, fiscal years 2009, 2010 and 2011 are the only years remaining open under applicable statutes of limitations.  Certain subsidiaries are also subject to income tax in foreign jurisdictions which have open tax years varying by jurisdiction extending back to 2004.  We operate under a tax holiday in China that will expire in fiscal 2012.  At this time, we are unable to predict how the expiration of the tax holiday will impact us in the future.

During the third quarter of fiscal 2011, the President signed into law a reinstatement of the research and development tax credit, retroactively to January 1, 2010. As a result, we recognized in the third quarter of fiscal 2011 approximately $686 in benefits for the credit for the ten months preceding the third quarter of fiscal 2011.
