Customer lists are generally amortized over five years and core deposit intangibles are generally amortized over 10 years, both at an accelerated rate.
Amortization expense of all amortizable intangible assets totaled $5.7 million, $6.6 million, and $8.0 million for the years ended December 31, 2025, 2024 and 2023, respectively.
Goodwill is evaluated for impairment on at least an annual basis, with the annual evaluation occurring as of October 31 of each year. Goodwill is also evaluated for impairment any time there is a triggering event indicating that impairment may have occurred. No triggering events were identified during 2025 or 2024 and, therefore, the Company did not perform interim impairment evaluations in either of those years. The Company's most recent evaluation of goodwill, which occurred in the fourth quarter of 2025, indicated that there was no goodwill impairment. There was no change to carrying amounts of goodwill during 2025 or 2024.
The following table presents the estimated amortization expense schedule related to amortizable intangible assets. These amounts will be recorded as "Intangibles amortization expense" within the noninterest expense section of the consolidated statements of income. These estimates are subject to change in future periods to the extent
management determines it is necessary to make adjustments to the carrying value or estimated useful lives of amortizable intangible assets.
