Goodwill

The Company's goodwill results from the acquisition of Keryx in December 2018. Goodwill was $55.1 million as of March 31, 2022 and December 31, 2021. The Company operates in one operating segment which the Company considers to be the only reporting unit. Goodwill is evaluated for impairment at the reporting unit level on an annual basis as of October 1, and more frequently if indicators are present or changes in circumstances suggest that an impairment may exist. During the first quarter of 2022, the Company evaluated business factors, including the receipt of a CRL from the FDA for vadadustat, to determine if there were events or changes in circumstance to indicate that the fair value of the reporting unit was less than its carrying value. The Company determined that it was not more likely than not that the fair value of the reporting unit was less than its carrying value and, accordingly, determined that there was no impairment of goodwill during the three months ended March 31, 2022.

However, the future occurrence of events including, but not limited to, an adverse change in current economic and market conditions, including a significant prolonged decline in market capitalization, a significant adverse change in legal factors, unexpected adverse business conditions and an adverse action or assessment by a regulator could indicate potential impairment and trigger an interim impairment assessment of goodwill. As a result of the significance of goodwill, the Company's results of operations and financial position in a future period could be negatively impacted should an impairment test be triggered that results in an impairment of goodwill.
