NOTE 5: NET EARNINGS (LOSS) PER SHARE

Our basic and diluted earnings (loss) per share for the last three years were:

•	$3.48 and $3.47, respectively, in 2021,
•	$1.07 in 2020 and
•	$(0.10) in 2019.

HOW WE CALCULATE BASIC AND DILUTED NET EARNINGS (LOSS) PER SHARE

Basic earnings (loss) per share is net earnings (loss) available to common shareholders divided by the weighted average number of our outstanding common shares, including stock equivalent units where there is no circumstance under which those shares would not be issued.

Diluted earnings (loss) per share is net earnings (loss) available to common shareholders divided by the sum of the:

•	weighted average number of our outstanding common shares and
•	the effect of our outstanding dilutive potential common shares.

Dilutive potential common shares may include:

•	outstanding stock options,
•	restricted stock units and

•	performance share units.

We use the treasury stock method to calculate the dilutive effect of our outstanding stock options, restricted stock units and performance share units. Share-based payment awards that are contingently issuable upon the achievement of specified performance or market conditions are included in our diluted earnings per share calculation in the period in which the conditions are satisfied.

The following shares were not included in the computation of diluted earnings (loss) per share because they were either antidilutive or the required performance or market conditions were not met. Some or all of these shares may be dilutive potential common shares in future periods.
