13.	Net Income (Loss) per Share

Basic net income (loss) per share is computed by dividing the net income (loss) by the weighted-average number of shares of common stock outstanding during the period. Diluted net income (loss) per share is computed by giving effect to all potential shares of common stock, including stock options, RSUs, and PSAs, to the extent dilutive. Performance-based PSAs are considered dilutive when the related performance conditions have been met assuming the end of the reporting period represents the end of the performance period. In periods with a net loss, all potential shares of common stock are excluded from the computation of diluted net loss per share as the impact would be antidilutive.

Net income (loss) per basic and diluted weighted-average common share outstanding was calculated as follows (in thousands, except per share amounts):

	Three Months Ended June 30,					Six Months Ended June 30,
	2019		2018			2019		2018

Net income (loss)	$	2,974	$	(5,686	)	$	5,139	$	(7,637	)

Basic weighted-average common shares outstanding		9,736		9,727			9,736		9,717
Effect of potentially dilutive common shares (1)		17		-			9		-
Diluted weighted-average common shares outstanding		9,753		9,727			9,745		9,717

Net income (loss) per common share:
Basic	$	0.31	$	(0.59	)	$	0.53	$	(0.79	)
Diluted	$	0.31	$	(0.59	)	$	0.53	$	(0.79	)

The weighted-average number of antidilutive shares

not

included in the computation of diluted net loss per share was approximately

64,000

and

75,000

for the

three

and

six

months ended

June

30,

2018,

respectively, including approximately

40,000

and

37,000,

respectively, of performance-based share awards, at the target level of

100%,

that were

not

included because the performance conditions had

not

been met as of

June

30,

2018.
