Loss Per Share

9 Months Ended

Sep. 30, 2020

Basic loss per share is computed by dividing net loss attributable to the Company’s stockholders by the weighted-average number of shares outstanding during the period. Diluted loss per share reflects all potential dilutive ordinary shares outstanding during the period and is computed by dividing net loss attributable to the Company’s stockholders by the weighted-average number of shares outstanding during the period increased by the number of additional shares that would have been outstanding as dilutive securities.

Basic and diluted loss per share is determined using the following information:

The holders of the Preferred Stock have nonforfeitable rights to common stock dividends or common stock dividend equivalents. Accordingly, the Preferred Stock qualifies as participating securities.

As a result of the net loss per share for the three and nine months ended September 30, 2020 and 2019, the inclusion of all potentially dilutive shares would be anti-dilutive. Therefore, dilutive shares of 11,430 and 1,510 were excluded from the computation of the weighted-average shares for diluted net loss per share for the three months ended September 30, 2020 and 2019, respectively, and dilutive shares of 8,453 and 1,299 were excluded from the computation of the weighted-average shares for diluted net loss per share for the nine months ended September 30, 2020 and 2019, respectively.

A summary of securities excluded from the computation of diluted earnings per share is presented below:
