Net Loss Per Share

(10) 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 restricted stock units, except in such case when their inclusion would be anti-dilutive.

	Quarter Ended March 31,
(in thousands, except per share amounts)	2020		2019
Numerator for basic and diluted net loss per share:
Net loss attributable to 3D Systems Corporation	$	(18,924)	$	(24,394)
Denominator for basic and diluted net loss per share:
Weighted average shares	114,590		113,267
Net loss per share - basic and diluted	$	(0.17)	$	(0.22)

For the quarters ended March 31, 2020 and March 31, 2019, 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 for the quarters ended March 31, 2020 and March 31, 2019 were 6,135 and 5,534, respectively.
