Net Income Per Share

A reconciliation of basic and diluted Net income per share is presented below:

(In thousands, except per share amounts)	2014		2013		2012
Basic:
Net income	$	472,658	$	440,065	$	556,807
Basic weighted shares outstanding	309,748		320,195		320,830
Net income per share	$	1.53	$	1.37	$	1.74
Diluted:
Net income	$	472,658	$	440,065	$	556,807
Weighted shares outstanding	309,748		320,195		320,830
Effect of dilutive securities:
Stock options, employee stock purchase plan shares, and restricted stock unit shares	2,149		2,823		3,667
Diluted weighted shares outstanding	311,897		323,018		324,497
Net income per share	$	1.52	$	1.36	$	1.72

In applying the treasury stock method, we excluded 1.6 million stock option shares and restricted stock unit (including performance-base restricted stock unit) shares for 2014 because their effect was anti-dilutive. While these shares have been anti-dilutive, they could be dilutive in the future. Anti-dilutive stock option shares totaled 2.0 million for 2013 and 1.8 million for 2012.
