Goodwill and Other Intangible Assets

Goodwill

There were no changes in the carrying amount of goodwill during 2020 and 2019. No accumulated goodwill impairment losses existed at December 31, 2020 and 2019. Goodwill is reviewed annually for impairment and more frequently if potential impairment indicators exist. No impairment indicators were identified during 2020 and 2019. The Company considered the potential impact of the COVID-19 pandemic on the market factors affecting the fair values of the reporting units in its annual impairment review in 2020 and determined such factors did not indicate a goodwill impairment for any of the reporting units with goodwill. All of the Company's goodwill is associated with the Property and Casualty business segment (See Note 20. Segment Information for additional information on the reportable business segment).
