Mortgage servicing rights result from our mortgage loan origination activities. Late and ancillary fees, included as part of mortgage banking income and reported as noninterest income in the Consolidated Statements of Income, aggregated less than $0.1 million during 2023 and 2022. We determined that no valuation allowance was necessary as of December 31, 2023 or December 31, 2022. The estimated fair value of mortgage servicing rights was $19.3 million and $17.7 million as of December 31, 2023 and December 31, 2022, respectively. The fair value of mortgage servicing rights is estimated using a valuation model that calculates the present value of estimated future net servicing cash flows, taking into consideration expected mortgage loan prepayment rates, discount rates, servicing costs and other economic factors, which are determined based on current market conditions. During 2023, fair value was determined using a discount rate of 11.0%, a weighted average constant prepayment rate of 7.44%, depending on the stratification of the specific right, and a weighted average delinquency rate of 0.29%. During 2022, fair value was determined using a discount rate of 11.25%, a weighted average constant prepayment rate of 6.6%, depending on the stratification of the specific right, and a weighted average delinquency rate of 0.28%. The weighted average amortization period was 8.6 years and 8.9 years as of December 31, 2023 and December 31, 2022, respectively.
