Goodwill is not amortized but, instead, is subject to impairment tests on at least an annual basis, and more frequently if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. Based on the continued capital markets downturn due to macroeconomic pressures, including inflation, along with the sharp decline in the overall bank industry as a result of the collapses of Silicon Valley Bank and Signature Bank in March 2023, a goodwill impairment test was performed in the first quarter of 2023. Based on its qualitative assessment, the Company concluded that it was not more likely than not that goodwill was impaired as of March 31, 2023. Therefore, no quantitative assessment was deemed necessary as of March 31, 2023.
