The Company tests goodwill for impairment at the reporting unit level annually during the fourth quarter of each fiscal year, or more frequently if events or circumstances indicate that the asset may be impaired. In the fourth quarter of fiscal 2023, the Company performed a quantitative assessment of goodwill impairment and concluded the fair value of each of the Company’s reporting units was at least two times the carrying value, and therefore no impairment was identified.
There were no events or changes in circumstances which triggered an impairment review during the three and six months ended December 30, 2023.
