Goodwill and Intangible Assets

6. Goodwill and Intangible Assets

Goodwill represents the excess of net book value over the estimated fair value of net tangible and identifiable intangible assets of a reporting unit. Goodwill is tested for impairment annually or more often if impairment indicators are present at the reporting unit level. If events occur or circumstances change that would more likely than not reduce fair values of the reporting units below their carrying values, goodwill will be evaluated for impairment between annual tests. No triggering events indicating goodwill impairment occurred during the six months ended March 31, 2020. Please refer to Note 7, "Goodwill and Intangible Assets" to the Company's consolidated financial statements included in the

2019 Annual Report on Form 10-K for further information on the goodwill impairment testing performed during fiscal year 2019.
