with this settlement , we reduced the liability for the equator earn out to $ 0 and recognized a $ 7.6 million increase in earnings ( no comparative amounts in 2017 and 2016 ) . during 2015 , we recognized a loss on the sale of equity securities of hlss , net of dividends received , of $ 1.9 million . effective march 31 , 2015 , we terminated the data access and services agreement with ocwen ( “ data access agreement ” ) ( no comparative amounts in 2017 and 2016 ) . 36 consolidated results of operations summary consolidated results following is a discussion of our consolidated results of operations for the years ended december 31 , 2017 , 2016 and 2015 . for a more detailed discussion of the factors that affected the results of our business segments in these periods , see “ segment results of operations ” below . the following table sets forth information on our results of operations for the years ended december 31 : replace_table_token_12_th _ n/m — not meaningful . 37 replace_table_token_13_th _ ( 1 ) these are non-gaap measures that are defined and reconciled to the corresponding gaap measures on pages 29 to 31 . revenue we recognized service revenue of $ 899.6 million , $ 942.6 million and $ 940.9 million for the years ended december 31 , 2017 , 2016 and 2015 , respectively . the decrease in service revenue for the year ended december 31 , 2017 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 buy-renovate-lease-sell business , which began operations in the second half of 2016 , and an increase in the renovation management business . the increase in service revenue in 2016 compared to 2015 was primarily driven by revenue growth in the real estate market , primarily due to growth in the volume of homes sold and the percentage of homes sold through auction on hubzu and increased volumes of higher value property preservation referrals . the increase in service revenue in the mortgage market was driven by the change in the billing model for new ocwen reo referrals in the servicer solutions business and revenue growth in the origination solutions business from new customers and volume growth with existing customers . however , these increases were more than offset by lower rates charged to ocwen for certain software services . also , service revenue was lower in the other businesses , corporate and eliminations segment , primarily due to lower customer relationship management revenue as we severed relationships with and reduced the volume of services provided to certain clients that were not profitable to us , and we experienced a reduction in volume from the transition of services from one customer to another . it infrastructure services also declined due to the transition of resources supporting ocwen 's technology infrastructure to ocwen . during the fourth quarter of 2015 , we began transitioning resources supporting ocwen 's technology infrastructure to ocwen as a part of the previously announced separation of technology infrastructure . we recognized reimbursable expense revenue of $ 39.9 million , $ 52.0 million and $ 107.3 million for the years ended december 31 , 2017 , 2016 and 2015 , respectively . the decreases in reimbursable expenses revenue were primarily due to 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 and a 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 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
