10. Net Loss Per Common Share

Basic earnings or loss per share of common stock is computed by dividing net loss by the weighted average number of shares of common stock outstanding during the period. Diluted earnings or loss per share of common stock is computed similarly to basic earnings or loss per share except the weighted average shares outstanding are increased to include additional shares from the assumed exercise of any common stock equivalents, if dilutive. The Company’s stock options, restricted stock awards and warrants are considered common stock equivalents while outstanding for this purpose. Diluted earnings are computed utilizing the treasury method for stock options, restricted stock awards and warrants. No incremental common stock equivalents were included in calculating diluted loss per share because such inclusion would be anti‑dilutive given the net loss reported for the three and nine months ended September 30, 2019 and 2018. The following table sets forth the computation of basic and diluted loss per share for the three and nine months ended September 30, 2019 and 2018 (in thousands, except share and per share amounts):


	Three Months Ended				Nine Months Ended
	2019		2018		2019		2018
Numerator:
Net loss attributed to common stockholders	$	(3,430)	$	(6,079)	$	(10,151)	$	(19,981)

Denominator:
Basic and diluted weighted average common shares outstanding		14,265,411		14,259,691		14,265,411		13,650,556
Basic and diluted net loss per share	$	(0.24)	$	(0.43)	$	(0.71)	$	(1.46)

The following potential common shares were not considered in the computation of diluted net loss per share as their effect would have been anti‑dilutive during the three and nine months ended September 30, 2019 and 2018:


	Three Months Ended		Nine Months Ended
	2019	2018	2019	2018
Stock options	2,546,268	2,823,732	2,546,268	2,823,732
Warrants	1,014,204	1,014,204	1,014,204	1,014,204
Restricted stock awards	607,000	—	607,000	—
