EARNINGS PER SHARE

3 Months Ended

Mar. 31, 2016

Basic earnings per share is computed by dividing income available to common shareholders by the weighted-average number of shares of common stock outstanding during the period. Diluted earnings per share is computed by dividing income available to common shareholders by the weighted-average number of shares of common stock outstanding during the period increased to include the number of additional shares of common stock that would have been outstanding if the potentially dilutive securities had been issued. Potentially dilutive securities include outstanding stock options, unvested restricted stock and unvested equity-settled RSUs. The dilutive effect of potentially dilutive securities is reflected in diluted earnings per share by application of the treasury stock method.

The following table sets forth the computation of basic and diluted earnings per share of common stock as follows:



	Three Months Ended March 31,
	2016		2015
Numerator for common earnings per share:

Numerator for basic and diluted earnings per share	$	23,899	$	14,714

Denominator for basic earnings per share:

During the three months ended March 31, 2016 and 2015, a total of 2,218 and 121 shares underlying equity-based awards, respectively, were outstanding but were not included in the computation of diluted earnings per share because the effect was anti-dilutive.
