(Loss) Earnings Per Share

Basic (loss) earnings per share is computed by dividing net (loss) income attributable to the Company’s stockholders by the weighted-average number of shares outstanding during the period. Diluted (loss) earnings per share reflects all potential dilutive ordinary shares outstanding during the period and is computed by dividing net (loss) income 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. For the periods prior to the IPO, the average number of ordinary shares outstanding used to calculate basic and diluted (loss) earnings per share was based on the ordinary shares that were outstanding at the time of the IPO.

As a result of the net loss per share for the three and six months ended June 30, 2019, the inclusion of all potentially dilutive shares would be anti-dilutive. Therefore, dilutive shares (in thousands) of 1,388 and 1,191 were excluded from the computation of the weighted-average shares for diluted net loss per share for the three and six months ended June 30, 2019, respectively.

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