For the three and nine months ended September 30, 2019 and 2020, basic and diluted net loss per share was determined by dividing net loss attributable to shareholders by the weighted average number of shares outstanding during the period. Diluted net loss per share is the same as basic net loss per share during the periods presented as the effects of the Company’s potential ordinary share equivalents are antidilutive since the Company had net losses for each period presented below.
