In accordance with US GAAP, the Company performs annual tests to identify potential impairment of goodwill. The tests are required to be performed annually and more frequently if events or circumstances indicate a potential impairment may exist. The Company compares the fair value of each reporting unit with its carrying amount, including goodwill. If the carrying amount of a reporting unit exceeds its fair value, an impairment loss is recognized in an amount equal to that excess.

Considering the recent economic conditions resulting from the COVID-19 pandemic, the Company conducted an interim goodwill impairment test as of March 31, 2020. The 2020 interim test indicated a goodwill impairment of $443.7 million within the Bank reporting unit resulting in the Company recording an impairment charge of the same amount in the first quarter of 2020. The primary causes of the goodwill impairment in the Bank reporting unit were economic and industry conditions resulting from the COVID-19 pandemic that caused volatility and reductions in the market capitalization of the Company and its peer banks, increased loan provision estimates, increased discount rates and other changes in variables driven by the uncertain macro-environment that resulted in the estimated fair value of the reporting unit being less than the reporting unit’s carrying value. The fair value of the reporting unit was determined using an income approach under the framework established for measuring fair value under ASC 820.

The Company has $43.1 million in goodwill remaining in its separate reporting units of Trust, Retail Brokerage and Investment Service businesses for which the Company's qualitative assessments based upon the asset and fee-based nature of the businesses did not indicate potential impairment as of March 31, 2020. The fair values of the reporting units are based upon management’s estimates and assumptions. Although management has used the estimates and assumptions it believes to be most appropriate in the circumstances, it should be noted that even relatively minor changes in certain assumptions used in management’s calculations could result in significant differences in the results of the impairment tests.
