Income Per Share

Basic income per share for 2017, 2016 and 2015 was computed by dividing income amounts by the weighted average number of common shares outstanding. Income amounts used to calculate basic and diluted income per share were as follows:



	Year Ended
	2017		2016		2015
Income from continuing operations	$	194,029	$	129,624	$	139,979
Net income from discontinued operations	—		—		21,163
Net income	$	194,029	$	129,624	$	161,142

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



	Year Ended
	2017	2016	2015
Common stock:
Weighted average basic shares outstanding	244,179	262,209	323,018
Dilutive effect of stock options and restricted shares	8,110	4,503	5,707
Weighted average diluted shares outstanding	252,289	266,712	328,725

Diluted income per share was computed by dividing income by the weighted average number of basic shares outstanding plus the potential common share effect of dilutive stock options and restricted shares. We excluded potential common shares of 1,168, 1,558 and 2,323 for 2017, 2016 and 2015, respectively, from our diluted income per share calculation as they would have had anti-dilutive effects.
