Diluted earnings per share is calculated to give effect to the potential dilutive effect that could occur if additional ordinary shares were assumed to be issued under securities or instruments that may entitle their holders to obtain ordinary shares in the future, which include share-based compensation awards (see Note 17—Share-based payments for additional details). The number of additional shares for inclusion in the diluted earnings per share calculation was determined using the treasury stock method.
