when loans are sold , servicing assets are recorded at fair value in accordance with asc topic 860 , transfers and servicing ( “ asc 860 ” ) . fair value is based on market prices for comparable servicing contracts , when available , or alternatively , is based on a valuation model that calculates the present value of estimated future net servicing income . the fair value of servicing rights is highly sensitive to changes in underlying assumptions . changes in the prepayment speed and discount rate assumptions have the most significant impact on the fair value of servicing assets . servicing fee income , which is reported on the income statement as mortgage servicing income and sba servicing income , is recorded for fees earned for servicing loans . the fees are based on a contractual percentage of the outstanding principal and are recorded as income when earned . the amortization of servicing assets is netted against loan servicing fee income . late fees and ancillary fees related to loan servicing are not material . stock-based compensation we periodically grant stock options to purchase our common stock and issue restricted stock to our employees and directors . the benefits provided under all of these plans are subject to asc topic 718 , compensation – stock compensation ( “ asc 718 ) . our results of operations for the years ended december 31 , 2019 , 2018 and 2017 were impacted by the recognition of non-cash expense related to the fair value of our share based compensation awards . the determination of fair value of stock-based payment awards on the date of grant using the black scholes model is affected by our stock price , as well as the input of other subjective assumptions . these assumptions include , but are not limited to , the expected term of stock options and our stock price volatility . our stock options have characteristics significantly different from those of traded options , and changes in the assumptions can materially affect the fair value estimates . current accounting guidance requires forfeitures to be estimated at the time of grant and revised , if necessary , in subsequent periods if actual forfeitures differ from those estimates . if actual forfeitures vary from our estimates , we will recognize the difference in compensation expense in the period the actual forfeitures occur . fair value of financial instruments asc topic 820 , fair value measurement ( “ asc 820 ” ) , defines fair value as the price that would be received to sell a financial asset , or paid to transfer a financial liability in an orderly transaction between market participants at the measurement date . the degree of management judgment involved in determining the fair value of assets and liabilities is dependent upon the availability of quoted market prices or observable market parameters . for financial instruments that trade actively and have quoted market prices or observable market parameters , there is minimal subjectivity involved in measuring fair value . when observable market prices and parameters are not available , management judgment is necessary to estimate fair value . in addition , changes in market conditions may reduce the availability of quoted prices or observable date . see note 15 of our consolidated financial statements as of december 31 , 2019 , included elsewhere in this annual report on form 10-k , for a complete discussion of fair value of financial assets and liabilities and their related measurement practices . income taxes we use the asset and liability method of accounting for income taxes . under this method , deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases . deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled . if current available information raises doubt as to the realization of the deferred 51 tax assets , a valuation allowance may be established . we consider the determination of this valuation allowance to be a critical accounting policy because of the need to exercise significant judgment in evaluating the amount and timing of recognition of deferred tax liabilities and assets , including projections of future taxable income . these judgments and estimates are reviewed on a continual basis as regulatory and business factors change . see note 10 of our consolidated financial statements as of december 31 , 2019 , included elsewhere in this annual report on form 10-k , for additional information . the jobs act contains provisions that , among other things , reduce certain reporting and other regulatory requirements for qualifying public companies . as an “ emerging growth company ” we have elected under the jobs act to retain the ability to delay the adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements are made applicable to private companies . however , at december 31 , 2019 , 2018 and 2017 , we have adopted all new accounting standards that could affect the comparability of our financial statements to those of other public entities . in the event we choose in the future to delay adoption of future accounting pronouncements applicable to public companies , our consolidated financial statements as of a particular date and for a particular period in the future may not be comparable to the financial statements as of such date and for such period of a public company situated similarly to us that is neither an emerging growth company nor an emerging growth company that has opted out of the extended transition period . story_separator_special_tag other service charges , commissions and fees were relatively steady at $ 10.4 million for the years ended december 31 , 2019 and december 31 , 2018 , with a slight decrease of $ 11,000 in 2019. this small decrease was attributable to a $ 717,000 decrease in residential mortgage loan originations fees offset by a $ 614,000 increase in application income from residential mortgage loans , as well as increases in various other service charge , commissions and fee accounts . total gain on sale of loans was $ 14.6 million for the year ended december 31 , 2019 compared to $ 10.3 million for the year ended december 31 , 2018 , an increase of $ 4.3 million , or

average premiums of 7.08 % compared to the sale of $ 93.3 million in sba loans with an average premium of 7.31 % in the same period in 2018. mortgage loan servicing income was $ 9.3 million for the year ended december 31 , 2019 compared to $ 12.0 million for the year ended december 31 , 2018 , a decrease of $ 2.7 million , or 22.5 % . the decrease in mortgage loan servicing income was due to the declining value of capitalized mortgage servicing assets and increased servicing asset amortization . included in mortgage loan servicing income for the year ended december 31 , 2019 was $ 6.2 million in mortgage servicing fees compared to $ 3.9 million for 2018 , and capitalized mortgage servicing assets of $ 6.9 million for the year ended december 31 , 2019 compared to $ 10.3 million for 2018. these amounts were offset by mortgage loan servicing asset amortization of $ 3.8 million for the year ended december 31 , 2019 compared to $ 2.2 million for the year ended december 31 , 2018. our total residential mortgage loan servicing portfolio was $ 1.17 billion at december 31 , 2019 compared to $ 804.2 million at december 31 , 2018. sba servicing income was $ 3.7 million for the year

december 31 , 2019 compared to $ 431.2 million as of december 31 , 2018. our sba servicing rights are carried at fair value . while our servicing portfolio grew , the inputs used to calculate fair value also changed , which resulted in a $ 238,000 charge to our sba servicing rights during the year ended december 31 , 2019. during the year ended december 31 , 2018 , we recorded a charge of $ 888,000 to our sba servicing rights . other noninterest income was $ 778,000 for the year ended december 31 , 2019 compared to $ 770,000 for the year ended december 31 , 2018 , a slight increase of $ 8,000 , or 1.0 % . the largest component of other noninterest income is the income on bank owned life insurance which totaled $ 470,000 and $ 478,000 , respectively , for the years ended december 31 , 2019 and 2018. year ended december 31 , 2018 compared to year ended december 31 , 2017 service charges on deposit accounts decreased $ 238,000 to $ 1.0 million for the year ended december 31 , 2018 compared to $ 1.3 million for the year ended december 31 , 2017. this decrease is mainly attributable to the decline in overdraft and analysis fees from 2017 to 2018. other service charges , commissions and fees increased $ 2.2 million to $ 10.4 million for the year ended december 31 , 2018 compared to $ 8.2 million for the year ended december 31 , 2017. this increase is attributable to a significant increase in underwriting and processing fees earned from our origination of residential mortgage loans coupled with smaller increases on various service charge , commission and fee accounts . total gain on sale of loans was $ 10.3 million in the year ended december 31 , 2018 compared to $ 9.4 million for the same period of 2017 , an increase of $ 913,000 or 9.7 % . gain on sale
