__________
(1)For the three months ended June 30, 2021, no shares were excluded from the computation of diluted earnings per share. For the six months ended June 30, 2021, awards of 51 thousand shares were excluded from the computation of diluted earnings per share because their inclusion would be anti-dilutive. In periods of net loss available to common stockholders, dilutive securities are excluded as their inclusion would have an anti-dilutive effect. Accordingly, for the three and six months ended June 30, 2020, awards of 362 thousand shares and options of 2.6 million shares with an exercise price ranging from $45.75 to $86.34 and awards of 956 thousand shares and options of 2.7 million shares with an exercise price ranging from $36.55 to $86.34 were excluded from the computation of diluted earnings per share, respectively.
