The following is a summary of the gross carrying amount and accumulated amortization of amortizable intangible assets as of March 31, 2023 and December 31, 2022, and the carrying amount of unamortized intangible assets as of those same dates.


	March 31, 2023			December 31, 2022
($ in thousands)	Gross Carrying Amount		Accumulated Amortization	Gross Carrying Amount	Accumulated Amortization
Amortizable intangible assets:
Customer lists	$	2,700	1,927	2,700	1,847
Core deposit intangibles	57,890		23,334	29,050	21,274

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 other intangible assets, excluding the SBA servicing assets, totaled $2.1 million and $1.0 million for the three months ended March 31, 2023 and 2022, respectively.

SBA servicing assets are recorded for the portions of SBA loans that the Company has sold but continues to service for a fee. Servicing assets are initially recorded at fair value and amortized over the expected lives of the related loans and are tested for impairment on a quarterly basis. SBA servicing asset amortization expense is recorded within noninterest income as an offset to SBA servicing fees within the line item "Other service charges, commissions, and fees." The following table presents the changes in the SBA servicing assets for the three months ended March 31, 2023 and 2022:


	Three months ended March 31,
($ in thousands)	2023		2022
Beginning balance, net	$	4,004	5,472
Add: New servicing assets	77		745
Less: Amortization and impairment expense	184		626
Ending balance, net	$	3,897	5,591

During the three months ended March 31, 2023 and 2022, the Company recorded $1.0 million and $0.8 million, respectively, in SBA guarantee servicing income. At March 31, 2023 and December 31, 2022, the Company serviced SBA loans totaling $380.6 million and $392.4 million, respectively, for others. There were no other loans serviced in any period presented.

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 2022 or 2021, and therefore, the Company did not perform interim impairment evaluations in either of those years. Each of the Company's goodwill impairment evaluations for the periods presented, including the most recent October 2022 evaluation, indicated that there was no goodwill impairment.

The following table presents the changes in carrying amounts of goodwill:


($ in thousands)	Total Goodwill
Balance at December 31, 2021	$	364,263
Net activity during 2022	—
Balance at December 31, 2022	364,263
Additions from acquisition of GrandSouth	114,487
Balance at March 31, 2023	$	478,750

In connection with the GrandSouth acquisition on January 1, 2023, the Company recorded $28.8 million in core deposit intangibles.

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.
