19. EARNINGS PER SHARE

Basic EPS is computed based upon the weighted average number of common shares outstanding during each period. Diluted EPS is computed on the basis of the weighted average number of common shares outstanding during each period plus the potential dilutive effect of certain share-based compensation awards as if they were converted into common shares. For the years ended December 31, 2015, 2014 and 2013, there were 1,474, 3,643 and 1,575 antidilutive share awards excluded from the computation of diluted EPS, respectively.

The following table sets forth the components of basic and diluted EPS:

Eversource		For the Years Ended December 31,
(Millions of Dollars, except share information)		2015		2014		2013
Net Income Attributable to Common Shareholders		$	878.5	$	819.5	$	786.0

Weighted Average Common Shares Outstanding:
	Basic		317,336,881		316,136,748		315,311,387
	Dilutive Effect		1,095,806		1,280,666		899,773
	Diluted		318,432,687		317,417,414		316,211,160
Basic EPS		$	2.77	$	2.59	$	2.49
Diluted EPS		$	2.76	$	2.58	$	2.49

RSU and performance share awards are included in basic weighted average common shares outstanding as of the date that all necessary vesting conditions have been satisfied. The dilutive effect of unvested RSU and performance share awards is calculated using the treasury stock method. Assumed proceeds of these awards under the treasury stock method consist of the remaining compensation cost to be recognized and a theoretical tax benefit. The theoretical tax benefit is calculated as the tax impact of the intrinsic value of the awards (the difference between the market value of the average awards outstanding for the period, using the average market price during the period, and the grant date market value).

The dilutive effect of stock options to purchase common shares is also calculated using the treasury stock method. Assumed proceeds for stock options consist of cash proceeds that would be received upon exercise, and a theoretical tax benefit. The theoretical tax benefit is calculated as the tax impact of the intrinsic value of the stock options (the difference between the market value of the average stock options outstanding for the period, using the average market price during the period, and the exercise price).
