Loans serviced for others are not included in the accompanying consolidated balance sheets. The unpaid principal balances of loans serviced for others totaled approximately $1.532 billion and $1.540 billion at December 31, 2022 and 2021.
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. Mortgage servicing rights are included in other assets on the balance sheets as of December 31, 2022 and 2021.
