10 NET LOSS PER SHARE
Basic loss per share is computed by dividing the net loss for the period available to ordinary shareholders by the weighted average number of Ordinary Shares outstanding during the period. Diluted net loss per share is computed by dividing the net loss for the period by the weighted average number of Ordinary Shares outstanding and, when dilutive, adjusted for the effect of all potentially dilutive shares, including share options, RSUs and warrants on an as-if-converted basis.
The following table sets forth the computation for basic and diluted net loss per share:
For the first half of 2009 and 2008, there were no differences in the weighted-average number of Ordinary Shares used for basic and diluted net loss per Ordinary Share as the effect of all potentially dilutive Ordinary Shares outstanding was anti-dilutive. As at 30 June 2009, there were 23.8 million (2008: 22.8 million) share options and RSUs outstanding that could potentially have a dilutive impact in the future but were anti-dilutive in the first half of 2009 and 2008.
