The basic earnings per share for the year amounted to US$1.84 (2018: US$1.04); the fully diluted earnings per share amounted to US$1.84 (2018: US$1.04).

Basic earnings / (loss) per share amounts are calculated by dividing net profit / (loss) for the year attributable to shareholders of the Company by the weighted average number of shares outstanding during the year.

Diluted earnings / (loss) per share amounts are calculated by dividing the net profit / loss attributable to shareholders of the Company by the weighted average number of shares outstanding during the year plus the weighted average number of shares that would be issued on the conversion of all the dilutive potential shares into ordinary shares.
