Impairment of Goodwill
The Company tests goodwill at the reporting unit level for impairment annually, during the fourth quarter of each fiscal year, or more frequently if events or circumstances indicate that the asset may be impaired. The Company determined that, based on its organizational structure and the financial information that is provided to and reviewed by the Company’s CODM during fiscal 2024, 2023 and 2022 that its reporting units were NE, SE and OSP.
No indications of impairment were identified under the qualitative assessment of goodwill impairment for fiscal years ending on June 29, 2024 and July 2, 2022.
In fiscal 2023, the Company performed a quantitative assessment of goodwill impairment for all reporting units. Based on our testing during the fourth quarter of fiscal 2023, 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.
