Net loss per share is computed under the provisions of ASC topic 260, Earnings Per Share. Basic loss per share is computed using net loss and the weighted average number of shares of common stock outstanding. Diluted loss per share reflects the weighted average number of shares of common stock outstanding plus any dilutive shares outstanding during the period. Potentially dilutive shares consist of shares issuable upon the exercise of stock options, restricted stock awards, and restricted stock units.

The following table sets forth the computation of basic and diluted net loss per common share (amounts in thousands, except per share amounts):

	Three months ended March 31,
	2020			2019
Numerator:
Net loss	$	(6,181	)	$	(544	)
Denominator:
Basic weighted average shares		23,803			23,036
Diluted weighted average shares		23,803			23,036
Loss per share:
Basic	$	(0.26	)	$	(0.02	)
Diluted	$	(0.26	)	$	(0.02	)

The Company calculates dilutive common stock equivalent shares using the treasury stock method. In periods where the Company has a net loss, no dilutive common stock equivalent shares are included in the calculation for diluted shares as they are considered anti-dilutive. The following table sets forth dilutive common stock equivalent shares calculated using the treasury stock method (in thousands):

	Three months ended March 31,
	2020		2019
Stock options		589		721
Restricted stock units		261		232
Restricted stocks		451		551
Total common stock equivalent shares		1,301		1,504

Share-based awards to purchase approximately 0.2 and zero million shares of common stock that had an exercise price in excess of the average market price of the common stock during the three months ended March 31, 2020 and March 31, 2019, respectively, were not included in the calculation of diluted loss per share because they were anti-dilutive..
