Goodwill and Goodwill Impairment Total goodwill was $375.7 million as of September 30, 2022 compared with $372.2 million as of December 31, 2021. The increase of $3.5 million is a result of the acquisition of HSBC’s West Coast mass retail market consumer banking business and retail business banking business on February 7, 2022. The Company’s policy is to assess goodwill for impairment at the reporting unit level on an annual basis or between annual assessments if a triggering event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. Impairment is the condition that exists when the carrying amount of goodwill exceeds its implied fair value.
