Net Loss Per Share

(2) Net Loss Per Share

The Company calculates basic earnings per share by dividing net loss by the weighted average common shares outstanding during the period. Diluted earnings per share is computed by dividing net loss by the weighted average number of common shares outstanding during the period increased to include, if dilutive, the number of additional common shares that would have been outstanding if the potential common shares had been issued. The Company’s potentially dilutive shares include stock options, restricted stock units and warrants for common stock.

Because the Company reported a net loss for the three and nine months ended September 30, 2018 and 2017, all potentially dilutive shares of common stock have been excluded from the computation of the dilutive net loss per share for all periods presented. Such potentially dilutive shares of common stock consist of the following:

	September 30,
	2018		2017
Potentially dilutive securities, excluded:
Outstanding stock options		604,265		820,587
Unvested restricted stock units		233		15,401
Warrants to purchase common stock		2,669,855		3,656,978
