| Income Taxes                         | INCOME TAXESThe following is a reconciliation of the beginning and ending amount of gross unrecognized tax benefits for uncertain tax positions, including positions which impact only the timing of tax benefits. Three Months Ended March 2, 2013 March 3, 2012Unrecognized tax benefits at beginning of year$2,209 $3,015Additions for current period tax positions133 88Reductions for prior period tax positions(159) —Changes in interest and penalties104 72Unrecognized tax benefits at end of period$2,287 $3,175 At March 2, 2013, the amount of unrecognized tax benefit, that would impact the effective tax rate if recognized, was $1,597.  The Company recognizes interest and penalties related to unrecognized benefits in income tax expense.  At March 2, 2013, the Company had $409 accrued for the payment of interest and penalties.Due to the various jurisdictions in which the Company files tax returns and the uncertainty regarding the timing of settlements, it is possible that there could be other significant changes in the amount of unrecognized tax benefits in the next twelve months; however, the amount cannot be estimated.The Company is regularly audited by federal, state and foreign tax authorities.  The Internal Revenue Service has completed its audits of the Company’s U.S. income tax returns through fiscal year 2009.  With few exceptions, the Company is no longer subject to income tax examinations by state or foreign tax jurisdictions for years prior to 2007.During the three months endedMarch 2, 2013, the Company recognized a $780 benefit related to the extension of the research and development tax credit in December 2012. |
