Goodwill Impairment Assessment

The Company performed its annual goodwill impairment assessment as of October 1, 2022, 2021, and 2020, respectively, and determined no reporting units' carrying values were in excess of their estimated fair value.

The fair value of reporting units, used in both the annual and any interim goodwill impairment assessments in 2022, 2021, and 2020, are classified as Level 3 measurements within the fair value hierarchy due to significant unobservable inputs such as discount rates, projections of revenue, cost of revenue and operating expense growth rates, long-term growth rates and income tax rates. The fair value methodology is described further in Note 1 – Basis of Presentation and Summary of Significant Accounting Policies.
