The Company evaluates goodwill for impairment annually on July 1 and upon the occurrence of certain triggering events or substantive changes in circumstances that indicate that the fair value of goodwill may be impaired. There were no triggering events identified during the first half of fiscal 2023 requiring an interim goodwill impairment test, and the Company did not record a goodwill impairment charge in any of the periods presented.

Impairment of goodwill is tested at the reporting unit level. A reporting unit is an operating segment or one level below an operating segment (referred to as a “component”). A component of an operating segment is required to be identified as a reporting unit if the component is a business for which discrete financial information is available and segment management regularly reviews its operating results. The Company most recently performed the quantitative impairment test for goodwill carried by two of its reporting units, consisting of a regional metals recycling operation and its network of auto parts stores, as of July 1, 2022. For the metals recycling and autos reporting units subject to the quantitative impairment test, the estimated fair value of the reporting unit exceeded its carrying amount by approximately 32% and 44%, respectively, as of July 1, 2022.

The determination of fair value of the reporting units used to perform the impairment test requires judgment and involves significant estimates and assumptions about the expected future cash flows and the impact of market conditions on those assumptions. Future events and changing market conditions may impact management's assumptions used to estimate the reporting units’ fair value. Although the Company believes the assumptions used in testing its reporting units’ goodwill for impairment are reasonable, a lack of recovery or further deterioration in market conditions from current levels, a trend of weaker than anticipated financial performance for the reporting units with allocated goodwill, a decline in the Company's share price from current levels for a sustained period of time, or an increase in the weighted average cost of capital, among other factors, could significantly impact the Company's impairment analysis and may result in future goodwill impairment charges that, if incurred, could have a material adverse effect on its financial condition and results of operations.
