Goodwill and Intangible Assets Disclosure [Abstract]

Goodwill and Other Intangible Assets

We 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 following tables represent the carrying value of goodwill and intangibles for the nine months ended September 30, 2020, which are reported in "Other assets" on the balance sheets:
