2. Net Income per Common Share

Net income per common share (“EPS”) is calculated in accordance with the Earnings per Share topic of the FASB Accounting Standards Codification (“Codification”), which requires the presentation of basic and diluted EPS. Basic EPS is computed using the weighted average number of common shares outstanding during the period. Diluted EPS is computed using the weighted average number of common shares outstanding during the period, plus the dilutive effect of potential common shares.

For the purpose of computing diluted EPS, weighted average shares outstanding have been adjusted for common shares underlying 3.0 million options and 2.2 million restricted stock units (“RSUs”) for the three and six months ended June 30, 2017. Weighted average shares outstanding have been adjusted for common shares underlying 4.3 million options and 2.2 million RSUs for the three and six months ended June 30, 2016.

The table below presents a reconciliation of weighted average common shares used in the calculation of basic and diluted EPS (in thousands):

	Three Months Ended June 30,				Six Months Ended June 30,
	2017		2016		2017		2016
Weighted average shares for basic EPS		112,443		110,339		112,205		110,133
Dilutive effect of options and RSUs		3,022		3,165		2,820		2,789
Weighted average shares for diluted EPS		115,465		113,504		115,025		112,922
