Mortgage servicing intangibles are amortized based on current prepayment assumptions and are adjusted to fair value periodically, if impaired. Fair value is estimated based on the present value of future cash flows over several interest rate scenarios, which are then discounted at risk-adjusted rates. The Company considers portfolio characteristics, contractually specified servicing fees, prepayment assumptions, delinquency rates, late charges, other ancillary revenue, costs to service and other economic factors. When available, fair value estimates and assumptions are compared to observable market data and the recent market activity and actual portfolio experience.

Estimated amortization of intangible assets for the next five years, as of December 31, 2018, is as follows (dollars in thousands):

Estimated Amortization
2019	$	3,056
2020		2,975
2021		2,246
2022		1,935
2023		1,811
