NET INCOME PER SHARE

Basic net income per share is computed by dividing net income during the period by the weighted-average number of shares of common stock outstanding during that period, less unvested restricted stock awards. Diluted net income per share is impacted by equity instruments considered to be potential common shares, if dilutive, computed using the treasury stock method of accounting.

The calculations for basic and diluted net income per share for fiscal 2018, 2017 and 2016 are as follows:



	2018		2017		2016
	(In thousands, except per share amounts)
Net income	$	345,777	$	204,101	$	203,086
Weighted-average common shares used to calculate basic net income per share	273,729		272,097		284,502
Stock-based awards	7,415		8,124		6,754
Weighted-average common shares used to calculate diluted net income per share	281,144		280,221		291,256
Net income per share - basic	$	1.26	$	0.75	$	0.71
Net income per share - diluted	$	1.23	$	0.73	$	0.70

The following table presents shares of Cadence’s common stock outstanding for fiscal 2018, 2017 and 2016 that were excluded from the computation of diluted net income per share because the effect of including these shares in the computation of diluted net income per share would have been anti-dilutive:



	2018	2017	2016
	(In thousands)
Long-term performance-based awards	50	152	1,069
Options to purchase shares of common stock	637	303	581
Non-vested shares of restricted stock	290	77	27
Total potential common shares excluded	977	532	1,677
