Amortization expense of all other intangible assets, excluding the SBA servicing assets, totaled $1.8 million and $2.1 million for the three months ended March 31, 2024 and 2023, respectively.

During the three months ended March 31, 2024 and 2023, the Company recorded $0.7 million and $1.0 million, respectively in SBA guaranteed servicing fee income. There was no impairment of SBA servicing assets at March 31, 2024 and December 31, 2023 and no significant changes in fair value assumptions from year end.

The following table presents the changes in the SBA servicing assets and SBA servicing income for the three months ended March 31, 2024 and 2023.


	Three months ended March 31,
	2024		2023
Beginning balance, net	$	3,350	4,004
Add: New servicing assets	224		77
Less: Amortization expense and impairment charges	437		184
Ending balance, net	$	3,137	3,897

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 2024 to date and, therefore, the Company did not perform interim impairment evaluations. The Company's most recent evaluation of goodwill, which occurred in the fourth quarter of 2023, indicated that there was no goodwill impairment. There was no change to carrying amounts of goodwill during the first quarter of 2024.

The following table presents the estimated amortization expense schedule related to acquisition-related amortizable intangible assets, excluding the SBA servicing 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 amortized intangible assets.
