In the three and nine months ended September 30, 2023, there were no common shares available for issuance under share-based compensation plans that were excluded from the calculation of diluted income (loss) per share because the assumed exercise or issuance of such shares would be anti-dilutive. In each of the three and nine months ended September 30, 2022, 3.0 million common shares available for issuance under share-based compensation plans were excluded from the calculation of diluted income (loss) per share because the assumed exercise or issuance of such shares would be anti-dilutive.
