Earnings Per Share [Abstract]  
Earnings Per Share
 
(3)   Earnings Per Share
 
Basic earnings per share (“EPS”) was computed by dividing net income by the number of weighted average shares of common stock outstanding during the quarters and six months ended July 2, 2011 and July 3, 2010. Diluted EPS was calculated to give effect to all potentially dilutive shares of common stock using the treasury stock method. The reconciliation of basic to diluted weighted average shares outstanding for the quarters and six months ended July 2, 2011 and July 3, 2010 is as follows:
 
                                 
    Quarter Ended     Six Months Ended  
    July 2,
 		    July 3,
 		    July 2,
 		    July 3,
 		 
    2011     2010     2011     2010  
 
Basic weighted average shares outstanding
    97,537       96,420       97,366       96,376  
Effect of potentially dilutive securities:
                               
Stock options
    1,378       1,062       1,217       842  
Restricted stock units
    307       542       343       561  
Employee stock purchase plan and other
    2       3       1       2  
                                 
Diluted weighted average shares outstanding
    99,224       98,027       98,927       97,781  
                                 
 
For the quarters ended July 2, 2011 and July 3, 2010, options to purchase 6 and 606 shares of common stock, respectively, were excluded from the diluted earnings per share calculation because their effect would be anti-dilutive. For the six months ended July 2, 2011 and July 3, 2010, options to purchase 193 and 606 shares of common stock, respectively, were excluded from the diluted earnings per share calculation because their effect would be anti-dilutive.
