Earnings Per Share [Abstract]

Earnings per share ("EPS")

15. Earnings per share (“EPS”)

The Company uses the two-class method of computing basic EPS due to the existence of non-vested restricted stock awards with nonforfeitable rights to dividends or dividend equivalents (referred to as participating securities). For the three and nine months ended September 30, 2019 and 2018, no significant adjustments were made to net income for purposes of calculating basic and diluted EPS. The following is a reconciliation of the weighted average shares used in diluted EPS computations.

	Three Months Ended September 30,				Nine Months Ended September 30,
	2019		2018		2019		2018

There were 1,814,544 and 2,088,843 weighted average outstanding stock options and restricted stock awards and units not included in the diluted EPS computation for the three months ended September 30, 2019 and 2018, respectively, and 1,880,423 and 359,172 weighted average outstanding stock options and restricted stock awards and units not included in the diluted EPS computation for the nine months ended September 30, 2019 and 2018, respectively, because inclusion of these awards was anti-dilutive or, for performance-based and market-based restricted stock awards and units, all necessary conditions had not been satisfied by the end of the respective period.
