be deferred for the first three years to the fourth and fifth year . the deferred amounts accrue an additional return . story_separator_special_tag replace_table_token_24_th other revenue – other revenue was $ 423 million for the year ended december 31 , 2019 compared to $ 473 million in the same period of 2018 , representing a decrease of $ 50 million as reflected in the following table . this decrease was largely the result of lower trading activity in 2019 ; however , the operating margin before transportation charges in 2019 was $ 85 million compared to $ 80 million in 2018. replace_table_token_25_th production costs – production costs for the year ended december 31 , 2019 decreased $ 17 million to $ 895 million , compared to $ 912 million for the same period of 2018 , resulting in a 2 % decrease . the decrease primarily related to cost savings resulting from our october 2019 organizational redesign and less downhole maintenance activity in 2019 compared to the prior year . general and administrative expenses – our general and administrative expenses decreased $ 9 million to $ 290 million for the year ended december 31 , 2019 compared to the same period of 2018 , predominantly due to cost savings attributable to our october 2019 organizational redesign and lower cash-settled stock-based compensation expense resulting from the approximately $ 8 decline in our stock price at december 31 , 2019 compared to december 31 , 2018. see the stock-based compensation section below . other expenses , net – other expenses , net was $ 363 million for the year ended december 31 , 2019 compared to $ 399 million for the same period of 2018 , representing a decrease of $ 36 million as reflected in the following table . the decrease was largely the result of lower trading activity , partially offset by higher elk hills power costs and transportation costs . replace_table_token_26_th 56 other non-operating expenses – other non-operating expenses for the year ended december 31 , 2019 increased $ 49 million to $ 72 million , compared to $ 23 million for the same period of 2018 , resulting in an approximately 200 % increase . this increase was primarily due to the implementation of fourth quarter 2019 operational efficiencies and an organizational redesign that reduced our workforce to approximately 1,250 employees , which is slightly more than half the employees we had at the time of our inception in 2014. we recorded a charge to other non-operating expenses of $ 41 million , consisting of $ 29 million in salary and severance expense and $ 12 million for other termination benefits . net income attributable to noncontrolling interests – the increase in net income attributable to noncontrolling interests of $ 26 million reflected the additional net income ( loss ) allocated to ecr for the full year of 2019 compared to 2018 starting in april , partially offset by the change in the fair value of derivative instruments held by the bsp jv in 2019. stock-based compensation our consolidated results of operations for the years ended december 31 , 2019 and 2018 include the effects of long-term stock-based compensation plans under which awards are granted annually to executives , non-executive employees and non-employee directors that are either settled with shares of our common stock or cash . our equity-settled awards granted to executives include stock options , restricted stock units and performance stock units that either cliff vest at the end of a three-year period or vest ratably over a three-year period , some of which are partially settled in cash . our equity-settled awards granted to non-employee directors are stock grants that vest immediately or restricted stock units that cliff vest after one year . our cash-settled awards granted to non-executive employees vest ratably over a three-year period . changes in our stock price introduce volatility in our results of operations because we pay cash-settled awards based on our stock price on the vesting date and accounting rules require that we adjust our obligation for unvested awards to the amount that would be paid using our stock price at the end of each reporting period . cash-settled awards , including executive awards partially settled in cash , account for almost 70 % of our total outstanding awards . equity-settled awards are not similarly adjusted for changes in our stock price . our ending stock price for each of the quarters in 2019 and 2018 was as follows : replace_table_token_27_th stock-based compensation is included in both g & a
