Residential mortgage loans serviced for others were $26.3 billion at December 31, 2020, $32.3 billion at December 31, 2019 and $22.2 billion at December 31, 2018. Excluded from residential mortgage loans serviced for others were loans sub-serviced for others of $68.1 billion, $62.8 billion and $56.8 billion at December 31, 2020, 2019, and 2018, respectively. On January 31, 2019, the Company purchased servicing rights for residential real estate loans that had outstanding principal balances at that date of approximately $13.3 billion. The purchase price of such servicing rights was approximately $144 million. Commercial mortgage loans serviced for others were $18.9 billion at December 31, 2020, $17.6 billion at December 31, 2019 and $15.5 billion at December 31, 2018.  Excluded from commercial mortgage loans serviced for others were loans sub-serviced for others of $3.3 billion at December 31, 2020, $3.4 billion at December 31, 2019 and $2.7 billion at December 31, 2018.

The estimated fair value of capitalized residential mortgage loan servicing assets was approximately $240 million at December 31, 2020 and $297 million at December 31, 2019. The fair value of capitalized residential mortgage loan servicing assets was estimated using weighted-average discount rates of 9.4% and 10.6% at December 31, 2020 and 2019, respectively, and contemporaneous prepayment assumptions that vary by loan type. At December 31, 2020 and 2019, the discount rate represented a weighted-average option-adjusted spread (“OAS”) of 918 basis points (hundredths of one percent) and 928 basis points, respectively, over market implied forward London Interbank Offered Rates (“LIBOR”). The estimated fair value of capitalized residential mortgage loan servicing rights may vary significantly in subsequent periods due to changing interest rates and the effect thereof on prepayment speeds. The estimated fair value of capitalized commercial mortgage loan servicing assets was approximately $160 million and $153 million at December 31, 2020 and 2019, respectively. An 18% discount rate was used to estimate the fair value of capitalized commercial mortgage loan servicing rights at December 31, 2020 and 2019 with no prepayment assumptions because, in general, the servicing agreements allow the Company to share in customer loan prepayment fees and thereby recover the remaining carrying value of the capitalized servicing rights associated with such loan. The Company’s ability to realize the carrying value of capitalized commercial mortgage servicing rights is more dependent on the borrowers’ abilities to repay the underlying loans than on prepayments or changes in interest rates.

The key economic assumptions used to determine the fair value of significant portfolios of capitalized servicing rights at December 31, 2020 and the sensitivity of such value to changes in those assumptions are summarized in the table that follows. Those calculated sensitivities are hypothetical and actual changes in the fair value of capitalized servicing rights may differ significantly from the amounts presented herein. The effect of a variation in a particular assumption on the fair value of the servicing rights is calculated without changing any other assumption. In

reality, changes in one factor may result in changes in another which may magnify or counteract the sensitivities. The changes in assumptions are presumed to be instantaneous.
