The Company recorded $2,304,000 and $3,278,000 in servicing assets associated with the guaranteed portion of SBA loans originated and sold during 2019 and 2018, respectively. During 2019 , 2018, and 2017, the Company recorded $1,340,000, $846,000, and $207,000 respectively, in related amortization expense. Servicing assets are recorded for loans, or portions thereof, that the Company has sold but continue 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." At December 31, 2019 and 2018, the Company serviced for others SBA loans totaling $309.1 million and $248.6 million, respectively.

Goodwill is evaluated for impairment on at least an annual basis, with the annual evaluation occurring on October 31 of each year – see Note 1 for additional discussion. For each of the years presented, the Company’s evaluation indicated that there was no goodwill impairment.
