Goodwill and Intangible Assets Disclosure [Abstract]

Goodwill and Other Intangible AssetsWe are required to review goodwill and indefinite-lived intangible assets annually for impairment. Goodwill impairment is tested at the reporting unit level on an annual basis and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. The Goodwill balance was $171.1 million as of March 31, 2021 and December 31, 2020.

The following table summarizes intangible assets with determinable useful lives by major category which are included in "Other Assets" on our Condensed Consolidated Balance Sheets:
