Earnings Per Share [Abstract]

Income (Loss) Per Share

INCOME (LOSS) PER SHARE

Basic per share amounts were computed using the weighted average number of common shares outstanding. Diluted per share amounts were calculated using the number of basic weighted average shares outstanding increased by dilutive potential common shares related to stock-based awards, as determined by the treasury stock method. The weighted average numbers of shares outstanding used to compute income (loss) per share were as follows (in thousands):

	Three Months Ended June 30,		Six Months Ended June 30,
	2019	2018	2019	2018
Shares used to calculate basic income (loss) per share	29,678	30,193	29,626	30,253
Dilutive effect of outstanding stock options, performance stock units and restricted stock units	—	283	—	280
Shares used to calculate diluted income (loss) per share	29,678	30,476	29,626	30,533

The weighted average numbers of shares outstanding listed in the table below were anti-dilutive and excluded from the computation of diluted income per share. In the case of stock options, this is because the average market price did not exceed the exercise price.

	Three Months Ended June 30,		Six Months Ended June 30,
	2019	2018	2019	2018
Stock options	7	—	17	—
Restricted stock units	1	—	29	—

In the case of restricted stock units, this is because unrecognized compensation expense exceeds the current value of the awards (i.e., grant date market value was higher than current average market price). These shares may be dilutive potential common shares in the future (in thousands):
