Earnings Per Share

Basic and diluted earnings per share amounts are calculated by dividing net income by the weighted average number of shares of common stock outstanding during the period, as follows:



	Year Ended
	September 29, 2018			September 30, 2017		October 1, 2016
	(In thousands, except per share amounts)
Numerator:
Net income (loss)	$	(95,533	)	$	138,833	$	187,838

Denominator:
Weighted average common shares outstanding	69,833			74,481		75,094
Effect of dilutive stock options and restricted stock units	—			3,647		3,693
Denominator for diluted earnings per share	69,833			78,128		78,787

Net income (loss) per share:
Basic	$	(1.37	)	$	1.86	$	2.50
Diluted	$	(1.37	)	$	1.78	$	2.38

The following table presents weighted-average dilutive securities that were excluded from the above calculation because their inclusion would have had an anti-dilutive effect under ASC Topic 260, Earnings per Share, due to application of the treasury stock method:



	As of
	September 29, 2018	September 30, 2017	October 1, 2016
Potentially dilutive securities:	(In thousands)
Employee stock options	2,061	—	477
Restricted stock units	1,460	6	3
Total	3,521	6	480

Had the Company reported net income in 2018 instead of a net loss, 3 million potentially dilutive securities would have been included in the calculation of diluted earnings per share.
