(1)For the years ended December 31, 2022, 2021 and 2020, a total of 68 thousand, 23 thousand and 253 thousand stock based awards, respectively, were excluded from the calculation of diluted earnings per share as their exercise prices would render them anti-dilutive.

(2)Contingent shares represent additional shares to be issued for purchase price earned by former owners of businesses acquired by us once future conditions have been met. For further details, refer to Note 18, Business Combinations.

(3)The denominator used in calculating diluted earnings per share did not include 0.2 million and 0.3 million performance share units for the twelve months ended December 31, 2022 and 2021, respectively. The performance conditions associated with these performance share units were not met and consequently none of these performance share units were considered as issuable for the years ended December 31, 2022 and 2021.
