The Company determined that adverse changes in macroeconomic trends as a consequence of the continuing COVID-19 pandemic constituted a triggering event under U.S. GAAP (Accounting Standards Codification (ASC) No. 350, “Intangibles - Goodwill and Other” and ASC No. 360, “Impairment or Disposal of Long-Lived Assets”). The Company completed its impairment analysis procedures as of March 31, 2020. The Company determined that there was no impairment of long-lived assets in any of the reporting units as of March 31, 2020.

On September 30, 2020, The Company performed its annual goodwill assessment for the Agility segment in accordance with the provisions of ASU 2017-04, by using a single-step approach that determines the carrying value of goodwill and compares it against the reporting unit’s fair value. The Company’s conclusion was consistent with the results of the March 31, 2020 impairment test.

The fair value measurement of goodwill for the Agility segment was classified within Level 3 of the fair value hierarchy because the Company used the income approach, which utilizes significant inputs that are unobservable in the market and the market multiple approach using comparable entities to further validate the carrying values. The Company believes it made reasonable estimates and assumptions to calculate the fair value of the reporting unit as of the impairment test measurement date. The carrying value of Goodwill was $2,150,000 and $2,108,000 as of December 31, 2020 and 2019, respectively.
