1 Weighted-average potential common shares relating to instruments that were not dilutive for the respective periods (and therefore not included in the diluted earnings per share calculation above) but could potentially dilute earnings per share in the future were 8.7 million, 9.8 million and 11.3 million for 2018, 2017 and 2016, respectively.
2 Due to the net losses in 2017 and 2016, 2.9 million and 3.2 million, respectively, of weighted-average share options and warrants outstanding and 57.7 million and 54.6 million, respectively, of weighted-average share awards outstanding were excluded from the diluted earnings per share calculation, as the effect would be antidilutive.
