Goodwill and Intangible Assets

6. Goodwill and Intangible Assets

Goodwill and intangible assets acquired in our consolidation of Entasis were recognized at fair value as of the consolidation date, February 17, 2022. The carrying amount of goodwill as of March 31, 2022 was $5.5 million. Intangible assets with definite lives are amortized over their estimated useful lives. The carrying basis and accumulated amortization of recognized intangible assets as of March 31, 2022 were as follows:

	March 31, 2022
	Carrying
(In thousands)	Amount
Intangible assets with indefinite life	$	69,500
Intangible asset with determinable life		35,500
Total	$	105,000

All intangible assets are related to in-process research and development. The intangible assets with indefinite life consist of antibacterial therapeutic products. The intangible asset with determinable life consists of a contract, which commences in 2023. The useful life of this intangible asset will be determined upon commercialization of the underlying product candidate. Thus, no amortization expense of determinable assets was recognized during the period ended March 31, 2022.

Goodwill and indefinite-lived intangible assets are not amortized but are tested at least annually for impairment, or more frequently if triggering events occur, based on the estimated fair value of the intangible asset.
