Payments for (Proceeds from) Mortgage Servicing Rights [Abstract] |
Loan Servicing | Loan Servicing Loans serviced for others are not included in the accompanying condensed consolidated balance sheets. The unpaid principal balances of loans serviced for others totaled approximately $1.6 billion and $1.5 billion at June 30, 2022 and December 31, 2021. The aggregate fair value of capitalized mortgage servicing rights was approximately $18.8 million and $15.2 million at June 30, 2022 and December 31, 2021, compared to the carrying values of $18.8 million and $15.2 million at June 30, 2022 and December 31, 2021, respectively. Comparable market values and a valuation model that calculates the present value of future cash flows were used to estimate fair value. For purposes of measuring impairment, risk characteristics including product type, investor type and interest rates, were used to stratify the originated mortgage servicing rights.
