Earnings Per Share [Abstract]

Net Loss Per Share

(17) Net Loss Per Share

We compute basic loss per share using net loss attributable to 3D Systems Corporation and the weighted average number of common shares outstanding during the applicable period. Diluted loss per share incorporates the additional shares issuable upon assumed exercise of stock options and the release of restricted stock and RSUs, except in such case when their inclusion would

be anti-dilutive.

For the years ended December 31, 2019, 2018 and 2017 the effect of dilutive securities, including non-vested stock options and restricted stock awards/units, was excluded from the denominator for the calculation of diluted net loss per share because we recognized a net loss for the period and their inclusion would be anti-dilutive. Dilutive securities excluded were 5,822, 5,015 and 5,341 shares for the years ended December 31, 2019, 2018 and 2017, respectively.
