The Company performs its annual impairment test for goodwill and other intangible assets as of the first day of the fourth fiscal quarter of each year, or more frequently, if events or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. We have assessed the changes in events and circumstances through the first quarter of fiscal 2024 and concluded that no triggering events occurred that required interim quantitative testing.
