Goodwill and Intangible Assets Disclosure [Abstract]

The Company had goodwill of $901.3 million at March 31, 2024 and December 31, 2023. The Company did not record any adjustments to goodwill during the three months ended March 31, 2024 and March 31, 2023.

The Company’s policy is to assess goodwill for impairment on an annual basis during the fourth quarter of each year, and more frequently if events or circumstances lead management to believe the value of goodwill may be impaired.

Other intangible assets with definite lives were $40.4 million at March 31, 2024, consisting of $38.5 million in core deposit intangibles and $2.0 million in customer relationship intangibles. At December 31, 2023, other intangibles assets were $43.3 million, consisting of $41.2 million in core deposit intangibles and $2.1 million in customer relationship intangibles. The following table summarizes the change in the balances of core deposit and customer relationship intangible assets, and the related accumulated amortization for the periods indicated below:

The Company amortizes core deposit intangibles and customer relationship intangibles based on the projected useful lives of the related deposits in the case of core deposit intangibles, and over the projected useful lives of the related client relationships in the case of customer relationship intangibles. The amortization periods typically range from six to eleven years. The estimated aggregate amortization expense related to our core deposit and customer relationship intangible assets for each of the next five years succeeding December 31, 2023, in order from the present, is $11.1 million, $10.0 million, $8.9 million, $7.2 million, and $4.0 million. The Company’s core deposit and customer relationship intangibles are evaluated annually for impairment or more frequently if events and circumstances lead management to believe their value may not be recoverable. The Company is unaware of any events and/or circumstances that would indicate the value of customer relationship intangible assets are impaired as of March 31, 2024.
