Amortization expense of all other intangible assets, excluding the SBA servicing assets, totaled $0.9 million and $0.7 million for the three months ended September 30, 2022 and 2021, respectively, and $2.9 million and $2.4 million for the nine months ended September 30, 2022 and 2021, 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 and nine months ended September 30, 2022 and 2021.

At September 30, 2022 and December 31, 2021, the Company serviced SBA loans totaling $396.1 million and $414.2 million, respectively, for others. There were no other loans serviced in any period presented.

There were no changes to the carrying amounts of goodwill for the three or nine months ended September 30, 2022.

Goodwill is evaluated for impairment on at least an annual basis, with the annual evaluation occurring as of October 31 of each year. The Company performed the required annual impairment testing in the fourth quarter of 2021. Management evaluated the events and circumstances in the third quarter of 2022 that could indicate that goodwill might be impaired and concluded that a subsequent interim test was not necessary.

The following table presents the estimated amortization expense schedule related to acquisition-related 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 amortized intangible assets.
