(12) EQUITY AND STOCK-BASED COMPENSATION

Earnings Per Share

The following table sets forth the number of weighted-average shares outstanding used in the computation of basic and diluted income per share:

	Three months ended		Nine months ended
	September 28,	September 29,	September 28,	September 29,
	2013	2012	2013	2012
Weighted-average number of common shares used in basic income per share	44.709	49.958	45.592	50.174
Dilutive securities — employee stock options, restricted stock shares and restricted stock units	0.328	0.080	0.548	0.625
Weighted-average number of common shares and dilutive securities used in diluted income per share	45.037	50.038	46.140	50.799

All stock options were included in the computation of diluted income per share for the three and nine months ended September 28, 2013. The total number of stock options not included in the computation of diluted income per share because their exercise price was greater than the average market price of common shares was 0.003 for both the three and nine months ended September 29, 2012. For the three and nine months ended September 28, 2013, 0.857 and 0.758 of unvested restricted stock shares and restricted stock units, respectively, were excluded from the computation of diluted income per share because required market thresholds for vesting were not met, compared to 1.784 and 0.931 that were excluded for the three and nine months ended September 29, 2012, respectively.

A detailed description of the awards granted under these plans is included in our 2012 Annual Report on Form 10-K and our Quarterly Report on Form 10-Q for the period ended March 30, 2013.
