GOODWILL AND OTHER INTANGIBLE ASSETS
Goodwill

The Company tests goodwill and indefinite-lived intangible assets for impairment during the fourth quarter of each year, or more frequently should circumstances change or events occur that would more likely than not reduce the fair value of a reporting unit below its carrying value.

No testing was deemed necessary in the first three months of 2022. The changes in the net carrying value of goodwill by segment are as follows (in millions):
