12.	Net Loss Per Share

Basic EPS are computed using the weighted average number of shares outstanding. Diluted EPS are computed using the weighted average number of shares outstanding adjusted for the incremental shares attributed to outstanding securities with a right to purchase or convert into common stock.

The following table sets forth the computation of basic and diluted net (loss) income per share (in thousands, except per share data).

For the year ended December 31, 2017, the computation of diluted net loss per share did not include restricted stock units convertible into 755 thousand shares, a dilutive effect of 103 thousand shares, since their inclusion would have been anti-dilutive. Options to purchase 120 thousand shares for the year ended December 31, 2017 were not included in the computation of diluted net loss per share as their exercise prices were in excess of the average stock prices for the year.

For the year ended December 31, 2016, the computation of diluted net loss per share did not include options to purchase approximately 750 thousand shares, a dilutive effect of 127 thousand shares, and restricted stock units convertible into 169 thousand shares, a dilutive effect of 17 thousand shares, since their inclusion would have been anti-dilutive. Options to purchase 220 thousand shares for the year ended December 31, 2016 were not included in the computation of diluted net loss per share as their exercise prices were in excess of the average stock prices for the year.

For the year ended December 31, 2015, the computation of diluted net loss per share did not include options to purchase approximately 825 thousand shares, a dilutive effect of 319 thousand shares, and restricted stock units convertible into 141 thousand shares, a dilutive effect of 26 thousand shares, since their inclusion would have been anti-dilutive.
