In 2018 and 2016, all potential common shares issuable for stock options and RSUs were excluded from the calculation of diluted loss per share, as the effect of including them would have been anti-dilutive. The dilutive effect of potential common shares issuable for stock options and RSUs on the weighted-average number of common shares outstanding would have been approximately 3,763,000 and 2,795,000 common shares for 2018 and 2016, respectively.

Additionally, in 2018, 2017 and 2016, stock options, time-based RSUs and performance-based RSUs to purchase approximately 4,185,000, 7,050,000 and 7,825,000 common shares of the Company, respectively, were not included in the computation of diluted earnings per share because the effect would have been anti-dilutive under the treasury stock method.
