For the three months ended September 30, 2021 and 2020, 0.2 million and 3.4 million stock options, respectively, and for the nine months ended September 30, 2021 and 2020, 0.4 million and 4.3 million stock options, respectively, were outstanding but were not included in the computation of diluted earnings per share. These stock options were excluded because their exercise prices were greater than the average market price of the common shares during the applicable period, making them anti-dilutive under the treasury stock method. For the three months ended September 30, 2021 and 2020, less than one thousand and eighteen thousand shares, respectively, and for the nine months ended September 30, 2021 and 2020, four thousand and 0.1 million shares, respectively, of unvested PSUs, RSUs and restricted stock were excluded from the calculation of diluted earnings per share due to their anti-dilutive effect.
