(1) The calculation of earnings per share is performed separately for continuing and discontinued operations. As a result, the sum of the two in any particular year may not equal the earnings-per-share amount in total.
(2) The loss per share for continuing operations in 2023 has not been diluted, since the incremental shares
included in the weighted-average number of shares outstanding would have been anti-dilutive.
