On December 12, 2018, the Company completed the Merger, whereby it acquired certain definite-lived intangible assets, including the developed product rights for Auryxia and a favorable lease. The Company amortizes its definite-lived intangible assets acquired as part of the Merger using the straight-line method, which is considered the best estimate of economic benefit, over its estimated useful life. As a result of the adoption of ASC 842 on January 1, 2019, the Company reclassed the remaining balance of the favorable lease intangible asset into the operating lease asset. The Company recorded $9.1 million in amortization expense related to the developed product rights for Auryxia during the three months ended March 31, 2019. Estimated future amortization expense for the intangible asset as of March 31, 2019 is as follows:

	Total
2019	$	27,301
2020		36,402
2021		36,401
2022		36,402
2023		36,401
Thereafter		145,606
	$	318,513

Goodwill

Goodwill was $55.1 million as of March 31, 2019 and December 31, 2018, derived as follows:

Total Merger consideration	$	527,754
Less: Fair value of identified acquired assets and liabilities, net		(472,701	)
Goodwill	$	55,053

Goodwill will be evaluated for impairment 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.
