​ The Company evaluates goodwill for impairment on an annual basis in accordance with FASB ASC 350, to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, and performs either a qualitative or quantitative assessment, depending on circumstances and management judgment. During 2023, the Company performed quantitative goodwill analyses for all applicable business entities. The inputs for the quantitative analyses include determination of the discount rate, forecasted financial performance of the business entity, macroeconomic and industry conditions, and other relevant events that affect the fair value of the reporting unit. Based on the Company’s annual impairment analysis of goodwill as of October 1, 2023, it was determined that the fair value of each reporting unit was in excess of its respective carrying value, therefore goodwill was not impaired. The Company performed a qualitative assessment for evaluating impairment of goodwill and other intangibles as of December 31, 2022, including assessments of macroeconomic conditions, industry and market considerations, cost factors, overall financial performance, other relevant entity-specific events and changes in share price. The results of the qualitative analysis indicated that there was no goodwill impairment at December 31, 2022 and therefore a quantitative analysis was not necessary. The Company also performs a quarterly analysis to determine if any triggering events have occurred that would require an interim evaluation. During 2023 and 2022, no triggering events or impairment was noted during these interim analyses. Under certain circumstances, the Company sells consumer residential mortgage loans in the secondary market and typically retains the right to service the loans sold. These mortgage servicing rights were immaterial at December 31, 2023 and 2022. The total principal balance of loans serviced for others was $532.9 million and $583.1 million at December 31, 2023 and 2022, respectively. The total custodial escrow balances maintained in connection with loans serviced for others was $10.2 million and $10.5 million at December 31, 2023 and 2022, respectively.
