entered into an amendment to its agreements with resi to sell altisource 's rental property management business to resi and permit resi to internalize certain services that had been provided by altisource . these services were historically provided under an agreement between resi and altisource , in which altisource was the sole provider of rental property management services to resi through december 2027 , subject to certain exceptions . in november 2018 , we announced plans to sell our short-term investments in real estate and discontinue the brs business . except for these changes , we continue focus on supporting and growing referrals from existing and new customers . share repurchase program on may 15 , 2018 , our shareholders approved the renewal and replacement of the share repurchase program previously approved by the shareholders on may 17 , 2017. under the program , we are authorized to purchase up to 4.3 million shares of our common stock , based on a limit of 25 %

december 31 : replace_table_token_12_th _ n/m — not meaningful . 38 replace_table_token_13_th _ ( 1 ) these are non-gaap measures that are defined and reconciled to the corresponding gaap measures on pages 28 to 32 . revenue we recognized service revenue of $ 805.5 million for the year ended december 31 , 2018 , a 10 % decrease compared to the year ended december 31 , 2017 . the decrease was driven by the reduction in the size of ocwen 's portfolio and number of delinquent loans in its portfolio resulting from loan repayments , loan modifications , short sales , reo sales and other forms of resolution in the mortgage market segment . service revenue in the real estate market segment increased for the year ended december 31 , 2018 as a result of higher transaction volumes and commission rates per transaction in the consumer real estate solutions business and growth in home sale revenue in the brs and renovation management businesses in real estate investor solutions , largely offset by a decline in revenues in the real estate investor solutions business from resi 's smaller portfolio of non-performing loans and reo , as resi continues to sell off this portfolio and focus on directly acquiring , renovating and managing rental homes . we recognized service revenue of $ 899.6 million for the year ended december 31 , 2017 , a 5 % decrease compared to the year ended december 31 , 2016 . the decrease was primarily due to lower service revenue in our it infrastructure services and customer relationship management businesses in the other businesses , corporate and eliminations segment and , in the mortgage market segment , a reduction in the size of ocwen 's portfolio and number of delinquent loans in its portfolio resulting from loan repayments , loan modifications , short sales , reo sales and other forms of resolution . it infrastructure services revenue declined from the transition of resources supporting ocwen 's technology infrastructure to ocwen . beginning in the fourth quarter of 2015 and continuing through 2017 , we transitioned resources supporting ocwen 's technology infrastructure from altisource to ocwen . the decrease in the customer relationship management service revenue was primarily due to severed client relationships with certain non-profitable clients and a reduction in volume from the transition of services from one customer to another . the declines in the mortgage market segment were partially offset by growth in property preservation and inspection business from ocwen as well as non-ocwen customers and the impact of the 2015 change in the billing model for preservation services on new ocwen reo referrals that resulted in certain services that were historically reimbursable expenses revenue becoming service revenue . furthermore , mortgage market service revenue from loan disbursement processing services increased from the full year impact of the granite acquisition in july 2016. service revenue in the real estate market was lower as a result of resi 's smaller portfolio of non-performing loans and reo , which was largely offset by increased service revenue from home sales in the brs business , which began operations in the second half of 2016 , and an increase in the renovation management business . we recognized reimbursable expense revenue of $ 30.0 million for the year ended december 31 , 2018 , a 25 % decrease compared to the year ended december 31 , 2017 . we recognized reimbursable expense revenue of $ 39.9 million for the year ended december 31 , 2017 , a 23 % decrease compared to the year ended december 31 , 2016 . the decreases in reimbursable expense revenue were primarily a result of , in the mortgage market segment , a reduction in the size of ocwen 's portfolio and number of delinquent loans in its portfolio resulting from loan repayments , loan modifications , short sales , reo sales and other forms of resolution , as discussed in service revenue above . in addition , the decrease for the year ended december 31 , 2017 was driven by the change in 2015 in the billing model for preservation services on new ocwen reo referrals described above , which impacted reimbursable expense revenue in the mortgage market . certain of our revenues are impacted by seasonality . more specifically , revenues from property sales , loan originations and certain property preservation services typically tend to be at their lowest level during the fall and winter months and at their highest level during the spring and summer months . in addition , revenue in the asset recovery management business typically tends to be higher in the first quarter , as borrowers may utilize tax refunds and bonuses to pay debts , and generally declines throughout the rest of the year . cost of revenue and gross profit cost of revenue principally includes payroll and employee benefits associated with personnel employed in customer service and operations roles , fees paid to external providers related to the provision of services , cost of real estate sold , reimbursable expenses , technology and telecommunications costs and depreciation and amortization of operating assets . 39 cost of revenue consists of the following for the years ended december 31 : replace_table_token_14_th n/m — not meaningful . we recognized cost of revenue of $ 622.2 million for the year ended december 31 , 2018 , an 11 % decrease compared to the year ended december 31 , 2017 . the decrease was primarily driven by lower service revenue from ocwen 's portfolio in the mortgage market segment , and related cost reduction initiatives and early benefits of project catalyst , partially offset by an increase in cost of real estate sold in the real estate investor solutions business . the decrease in outside fees and services in the servicer solutions business in the mortgage market segment was driven by lower property preservation and
