Indefinite life intangible assets are not amortized, rather they are subject to annual impairment tests. Finite life intangibles are amortized over their useful lives unless circumstances occur that cause the Company to revise such lives or review such assets for impairment. In connection with the Company’s decision to exit the Grow Tech segment, a $3.8 million impairment charge related to other indefinite lived intangibles and a $5.2 million impairment charge related to other finite lived intangibles was recorded in the year ended December 31, 2021, see Note 20 for further discussion restructuring and impairment of the Grow Tech segment. During 2022, the Company recorded a $1.7 million impairment charge for other intangibles associated with our 2022 restructuring, see Note 20 for further discussion.
