Annual impairment testing description								While the Company’s annual impairment testing date is on April 1, 2025 (the first day of the fourth quarter of fiscal 2025), the previously aforementioned quantitative tests for the U.S. and Canada reporting units were utilized for the annual impairment test given there were no significant changes to the risks of these reporting units between March 31, 2025 and April 1, 2025. However, the Company performed quantitative tests for its other three reporting units (Western Europe, Ella’s Kitchen and U.K.) on April 1, 2025, which corroborated the results of the qualitative analysis that was performed during the third quarter of fiscal 2025. The fair values of Western Europe and Ella’s Kitchen significantly exceeded their carrying values.
