____________________

(1)The performance share unit awards are contingently issuable and are considered in the calculation of diluted earnings per share. The Company assesses the number of awards that would be issuable, if any, under the terms of the agreement if the end of the reporting period were the end of the contingency period.
(2)The incremental shares of potentially dilutive restricted stock units and restricted stock awards were included for the three and nine-month periods ended September 30, 2021 as their effect was dilutive under the treasury stock method.
(3)No incremental shares of potentially dilutive restricted stock awards, performance share units, warrants or stock options were included for the three and nine-month periods ended September 30, 2020, as their effect was antidilutive under the treasury stock method.
