Goodwill resulting from the business combinations has been allocated to the single reporting unit of the Company. For the years ended December 31, 2020, 2021 and 2022, the Company performed a qualitative assessment by evaluating relevant events and circumstances that would affect the Company’s single reporting unit and did not note any indicator that it is more likely than not that the fair value of the Company’s reporting unit is less than its carrying amount, and therefore the Company’s goodwill was not impaired. As of December 31, 2022, there had not been any accumulated goodwill impairment provided.
