Loss Per Share

12. LOSS PER SHARE

Basic loss per ordinary share is calculated based upon net loss available to holders of ordinary shares divided by the weighted average number of shares outstanding. For the years ended December 31, 2020, 2019 and 2018, as the Company was in a net loss position, the diluted loss per share did not assume conversion or exercise of stock options and awards as they would have had an anti-dilutive effect on loss per share.

The following potential ordinary share equivalents were not included in the net loss per ordinary share calculation because the effect would have been anti-dilutive:
