The Bank has sold loans in the secondary market and has retained the servicing responsibility and receives fees for the services provided. Mortgage loans sold and serviced for others amounted to $625.4 million, $641.2 million, and $603.7 million at year-end 2014, 2013, and 2012, respectively. Mortgage loans serviced for others are not included in the accompanying consolidated balance sheets. The risks inherent in mortgage servicing assets relate primarily to changes in prepayments that result from shifts in mortgage interest rates. Contractually specified servicing fees were $1.5 million, $1.5 million, and $2.8 million for the years 2014, 2013, and 2012, respectively, and included as a component of loan related fees within non-interest income. The significant assumptions used in the valuation at year-end 2014 included a weighted average discount rate of 10.4% and pre-payment speed assumptions ranging from 7.83% to 19.00%.
