Basic and diluted net income per common share:

Earnings Per Share of Common Stock

4. EARNINGS PER SHARE OF COMMON STOCK

Basic and diluted earnings per share are calculated in accordance with ASC 260, “Earnings Per Share”. Under ASC 260, basic earnings per share is computed by dividing income available to common shareholders by the weighted-average number of common shares outstanding for the period. The computation of diluted earnings per share is similar to basic earnings per share, except that the denominator is increased to include the potential dilution from the exercise of stock options and warrants for common shares using the treasury stock method. The numerator in calculating both basic and diluted earnings per common share for each period is the reported net income.

The denominator is based on the following weighted average number of common shares:

	Three Months Ended March 31,
	2018		2017
Basic weighted average common shares outstanding		8,108,934		8,135,036
Incremental shares for assumed exercise of options		12,794		23,280
Diluted weighted average common shares outstanding		8,121,728		8,158,316

57,849 and 27,751 vested options and warrants were not included in the diluted earnings per share calculation for the three month periods ended March 31, 2018 and 2017, respectively, because their effect would have been anti-dilutive.
