9. Earnings (Loss) per Share

Basic and diluted loss per share

For the three months ended March 31, 2018 and 2019, 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 and thus not included in the calculation.
