Mortgage Servicing Rights

Mortgage Servicing Rights

(In Thousands)

The Company retains the right to service certain mortgage loans that it sells to secondary market investors. These mortgage servicing rights (“MSRs”) are recognized as a separate asset on the date the corresponding mortgage loan is sold. MSRs are amortized in proportion to and over the period of estimated net servicing income. These servicing rights are carried at the lower of amortized cost or fair value. Fair value is determined using an income approach with various assumptions, including expected cash flows, prepayment speeds, market discount rates, servicing costs, and other factors, and is subject to significant fluctuation as a result of actual prepayment speeds, default rates and losses differing from estimates thereof. Servicing rights are evaluated for impairment based upon the fair value of the rights as compared to the carrying amount. Impairment is recognized through a valuation allowance in the amount that unamortized cost exceeds fair value. If the Company later determines that all or a portion of the impairment no longer exists, a reduction of the valuation allowance may be recorded as an increase to income. Changes in valuation allowances related to servicing rights are reported in "Mortgage banking income" on the Consolidated Statements of Income.

There were $14,522 of valuation adjustments on MSRs during the six months ended June 30, 2020, primarily arising on account of the difference between actual prepayment speeds and the Company's assumptions with respect to prepayment speeds; no valuation adjustments were recognized during the six months ended June 30, 2019. A continued decline in mortgage interest rates and an increase in actual prepayment speeds may cause additional negative adjustments to the valuation of the Company's MSRs.

Changes in the Company’s MSRs were as follows: 

Balance at January 1, 2020	$	53,208
Capitalization	19,425
Amortization	(6,637)
Valuation adjustment	(14,522)
Balance at June 30, 2020	$	51,474
