Income (loss) per share is calculated by dividing the income (loss) attributable to Company shareholders by the weighted number of outstanding ordinary shares during the period. Ordinary shares underlying shares options or restricted Shares are only included in the calculation of diluted income (loss) per share when their impact dilutes the income (loss) per share. Furthermore, potential ordinary shares converted during the period are included under diluted income (loss) per share only until the conversion date, and from that date on are included under basic income (loss) per share.
