Net Income (Loss) Per Share

Basic net income (loss) per share was computed by dividing net income (loss) amounts by the weighted average number of common shares outstanding.

The weighted average number of shares used to calculate basic and diluted net income (loss) per share were as follows:



	Three Months Ended		Six Months Ended
	July 1, 2018	July 2, 2017	July 1, 2018	July 2, 2017
Common stock:
Weighted average basic shares outstanding	238,991	245,261	239,459	245,933
Dilutive effect of stock options and restricted shares	7,161	—	7,826	7,963
Weighted average diluted shares outstanding	246,152	245,261	247,285	253,896

Diluted net income (loss) per share for the three and six months ended July 1, 2018 and July 2, 2017 was computed by dividing net income (loss) by the weighted average number of basic shares outstanding plus the potential common share effect of dilutive stock options and restricted shares. For the three and six months ended July 1, 2018, we excluded potential common shares of 27 and 1,369, respectively, from our diluted net income per share calculation as they would have had anti-dilutive effects. Diluted net loss per share for the three months ended July 2, 2017 was the same as basic net loss per share since the Company reported a net loss and, therefore, the effect of all potentially dilutive securities would have been anti-dilutive. For the six months ended July 2, 2017, we excluded potential common shares of 119 from our diluted net income per share calculation as they would have had anti-dilutive effects.
