The Company tests goodwill for impairment on an annual basis as of the beginning of the fourth quarter each year, or more frequently if indicators of potential impairment exist. Goodwill impairment testing is conducted at the reporting unit level, which is generally defined as an operating segment or one level below an operating segment (also known as a reporting unit), for which discrete financial information is available and segment management regularly reviews the operating results of that reporting unit.

At the beginning of the fourth quarter of fiscal 2022, the annual goodwill impairment assessment was completed. The Company performed a qualitative assessment for each reporting unit except for two within the Automotive segment where a quantitative assessment was performed. The qualitative assessments indicated that it was more likely than not that the fair value of each reporting unit exceeded its respective carrying value.

For the quantitative assessment, the Company utilized the income approach to estimate the fair value of the reporting units. Cash flow projections were based on management’s estimates of revenue growth rates and earnings before interest, taxes, depreciation and amortization (“EBITDA”) margins, taking into consideration business and market conditions for the countries and markets in which the reporting unit operates. The Company calculates the discount rate based on a market-participant, risk-adjusted weighted average cost of capital, which considers industry specific rates of return on debt and equity capital for a target industry capital structure, adjusted for risks associated with business size, geography and other factors specific to the reporting unit.

The quantitative assessment of the reporting units indicated that the fair value exceeded the carrying value. The Company does not believe that any of its reporting units are at risk for impairment. While the Company considered the impact the COVID-19 pandemic may have on its future cash flows when preparing its annual goodwill impairment test, the full extent of the impact that the COVID-19 pandemic, the semiconductor supply shortage and inflationary impact on materials, labor and freight costs will have on the Company’s business, operations and financial condition is currently unknown. The Company will continue to assess its goodwill for impairment as events and circumstances change. Any deterioration in the Company’s forecasted revenue and EBITDA margins, could result in an impairment of a portion or all of its goodwill. The amount of such impairment would be recognized as an expense in the period the goodwill is impaired.
