Basic (loss) earnings per ordinary share is calculated based upon net (loss) income available to holders of ordinary shares, divided by the weighted average number of ordinary shares outstanding. For the calculation of diluted (loss) earnings per ordinary share, the Company utilizes the treasury stock method and adjusts the weighted average number of ordinary shares outstanding for the potential dilutive effect of outstanding ordinary share equivalents such as stock options and restricted stock unit awards.
