Earnings Per Share, Basic and Diluted [Abstract]

Basic and Diluted Net Income (Loss) Per Share

Basic and Diluted Net Income (Loss) Per Share

We present net loss per share attributable to common stockholders in conformity with the two-class method required for participating securities, as the warrants are considered participating securities. We have not allocated net loss attributable to common stockholders to warrants because the holders of our warrants are not contractually obligated to share in our losses. Basic net loss per share attributable to common stockholders is computed by dividing net loss attributable to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted net loss per share attributable to common stockholders is calculated to give effect to all potential shares of common stock, including common stock issuable upon exercise of warrants, stock options, and RSUs. In periods for which there is a net loss, diluted loss per common share is equal to basic loss per common share, since the effect of including any common stock equivalents would be antidilutive.

The following table sets forth the reconciliation of shares used to compute basic and diluted net loss income per share for the periods indicated (in thousands):

(1) Earnings per share may not add due to rounding.

The computation of diluted earnings per share excludes stock options and stock units that are anti-dilutive. The following common stock equivalents were anti-dilutive (in thousands):

	Three Months Ended September 30,		Nine Months Ended September 30,
	2020	2019	2020	2019
Stock options	36	162	45	120
Stock warrants	2,102	—	999	—
Restricted stock units	23	34	28	32
Total	2,161	196	1,072	152

As of September 30, 2020, 0.4 million warrants were exercised and 2.1 million warrants remained outstanding at an exercise price of $2.25. See Note 1, Basis of Presentation, within the notes to our unaudited condensed consolidated financial statements for further detail.
