Net Loss Per Share

(14) Net Loss Per Share

The computation of basic and diluted net loss per share consists of the following:

	Year ended December 31,
	2018			2017			2016
	(In thousands, except share and per share data)
Numerator:
Net loss	$	(34,440	)	$	(19,321	)	$	(12,023	)
Denominator:
Weighted average shares outstanding, basic and diluted		23,738,852			23,390,235			23,139,807
Net loss per share, basic and diluted	$	(1.45	)	$	(0.83	)	$	(0.52	)

Potentially dilutive common shares that were excluded from the computation of diluted net loss per share because they were anti-dilutive consist of the following:

	Year ended December 31,
	2018		2017		2016
Common stock options		2,994,452		2,432,906		2,063,574
Restricted common stock units		875,227		827,391		682,085
Common stock warrants		—		—		115
Restricted common stock awards		136,187		151,859		153,277
Total		4,005,866		3,412,156		2,899,051

In the table above, anti-dilutive shares consist of those common stock equivalents that have (i) an exercise price above the average stock price for the period or (ii) related average unrecognized stock compensation expense sufficient to buy back the entire amount of shares. The Company excludes the shares issued in connection with restricted stock awards from the calculation of basic weighted average common shares outstanding until the restrictions lapse.

As of December 31, 2018 and 2017, there was no dilutive impact of the common stock options, RSUs, common stock warrants and restricted stock awards.
