During the fourth quarter of 2021, the Company completed its annual goodwill impairment test. Based on its assessment of the qualitative factors, the Company’s management concluded that the fair value of the Company’s goodwill was more likely than not greater than its carrying amount as of December 31, 2021. As such, it was not necessary to perform the quantitative goodwill impairment test. Subsequent to the 2021 annual impairment test, the Company believes there have been no significant events or circumstances negatively affecting the valuation of goodwill. As of December 31, 2021 and 2020, there was no impairment to the carrying value of the Company’s goodwill.
