we believe future acquisitions could strengthen our competitive position , enhance the products and services that we can offer to customers , expand our customer base , grow our revenues and increase our overall value . fiscal 2014 acquisition in october 2013 , we entered into a tender offer agreement with cameleon software sa ( `` pros france `` ) . as a result of shares purchased in the market following the completion of the tender in january 2014 , the exercise of warrants in july 2014 , and second tender completed in november 2014 , we controlled 100 % of pros france 's common stock as of december 31 , 2014. we acquired pros france for total cash consideration of approximately $ 32 million , net of cash acquired . fiscal 2013 acquisition in december 2013 , we acquired signaldemand , inc. for total cash consideration of $ 13.5 million . financing activities in december 2014 , we issued $ 143.8 million aggregate principal amount of 2.0 % convertible senior notes due december 1 , 2019 , unless earlier purchased or converted . interest is payable semiannually in arrears on june 1 and december 1 of each year , commencing on june 1 , 2015. backlog our backlog is derived from agreements that we believe to be firm commitments to provide software solutions and related services in the future . our backlog is based on significant estimates and judgments that we make regarding total contract values , as well as maintenance renewals and changes to existing maintenance and support agreements . backlog includes committed maintenance , amounts under maintenance and support agreements that we reasonably expect to renew , as well as deferred revenue . we compute our backlog as of a specific date , and we update our backlog to reflect changes in our estimates and judgments or subsequent additions , delays , terminations or reductions in our agreements . backlog can vary significantly from period to period depending on a number of factors including the timing of our sales and the nature of the agreements we enter into with our customers . for example , we have agreements that include non-standard provisions which require us to exercise judgment over the extent to which to include these agreements in our backlog . however , based on our history of successfully implementing our software solutions , we generally include the full estimated value of these agreements in backlog . for these and other reasons , our backlog may not be a meaningful indicator of future revenue to be recognized in any particular quarter , and there can be no assurance that our backlog at any point in time will translate into revenue in any specific quarter . furthermore , as we continue our migration to a saas provider , our historical definition of backlog and the relevance to our future revenues may change . we had backlog of approximately $ 209 million as of december 31 , 2015 as compared to backlog of approximately $ 194 million as of december 31 , 2014 . the portion of our backlog as of december 31 , 2015 not reasonably expected to be recognized as revenue within the next twelve months is estimated to be approximately $ 86 million . opportunities , trends and uncertainties we have noted opportunities , trends and uncertainties that we believe are particularly significant to understand our financial results and condition . 28 cloud-first strategy . we have historically sold the majority of our products via perpetual licenses . we also sold our solutions via term licenses or saas , which defers revenue recognition . in connection with our subscription based cloud-first strategy announced in 2015 , we expect to sell a lower percentage of perpetual licenses and more subscription-based solutions such as saas and subscription cloud-based solutions . following a transition period , we expect this business model will increase our recurring subscription revenue . we anticipate that this strategy will result in lower license revenue , lower total revenues and lower operating cash flows in 2016. however , we do not anticipate a corresponding decrease in expenses in 2016 , which will adversely affect our net income , operating margins and cash flow . variability in bookings . historically , we have experienced the strongest customer demand in fourth and second quarters of each year . however , the size and timing of orders for our products and services varies considerably , which can cause significant fluctuations in our bookings results from quarter to quarter . due to our average deal sizes , our bookings in any particular quarter have in the past , and may continue in the future , to be dependent on a relatively small number of orders . during 2015 , we experienced unanticipated sales execution challenges which we believe stemmed from the pace of change associated with our cloud-first strategy . the timing of our bookings also varies based on a number of factors over which we may have little or no control , including the complexity of the transaction , our customers ' internal budgeting and approval processes , our customers purchasing behaviors and the level of competition . variability in revenue . the timing of our revenue recognition varies based on the nature and requirements of our contracts . in conjunction with our cloud-first announcement in 2015 , we expect to have an increasing number of subscription contracts , which will result in less license revenue recognized in 2016. the timing of our revenue recognition for our saas solutions also varies based on the mix of products sold . for example , our saas solutions purchased by our travel customers often require more complex implementations which can delay the commencement of subscription revenue recognition . story_separator_special_tag deferred revenue does not reflect the total contract value of our customer arrangements at any point in time as we only record deferred revenue if amounts are invoiced in advance of the corresponding recognition of license and implementation revenue . as a result , there is little correlation between the timing of our revenue recognition , the timing of our invoicing and the amount of deferred revenue . 32 results of operations comparison of year ended december 31 , 2015 with year ended december 31 , 2014 revenue : replace_table_token_5_th license revenue . for the year ended december 31 , 2015 , license revenue decreased $ 25.8 million to $ 32.7 million from $ 58.5 million for the year ended december 31 , 2014 , representing a 44 % decrease . our license revenue is dependent on the amount of perpetual licenses sold in the period , as well as the timing of revenue recognition . as a result of our shift to a cloud-first strategy , we experienced a decrease in the sale of perpetual licenses and a corresponding decrease in license revenue , which included a decrease of $ 18.2 million in license revenue recognized upon software delivery . we recognized $ 9.0 million and $ 27.2 million of license revenue upon software delivery for the years ended december 31 , 2015 and 2014 , respectively . as a result of our shift to a cloud-first strategy , we expect customers will be purchasing more subscription-based solutions such as saas and cloud-based solutions , resulting in lower future license revenue . services revenue . for the year ended december 31 , 2015 , services revenue decreased $ 6.4 million to $ 42.9 million from $ 49.2 million for the year ended december 31 , 2014 , representing a 13 % decrease . the decrease in services revenue was primarily attributable to several customer implementations that were completed in 2014 with significant professional services and to a lesser extent certain pre-packaged offerings requiring less professional services . in addition , even though the total number of customers generating services revenue increased to 212 for the year ended december 31 , 2015 , as compared to 193 in the corresponding period in 2014 , an increase of 10 % , the decrease in services revenue was also attributed to an overall lower effective services man-day rate . subscription revenue . for the year ended december 31 , 2015 , subscription revenue increased $ 5.5 million to $ 29.0 million from $ 23.5 million for the year ended december 31 , 2014 , representing a 24 % increase . the increase in subscription revenue was primarily attributable to an increase in the number of customers subscribing to our saas and cloud-based solutions . the total number of customers generating subscription revenue was 102 for the year ended december 31 , 2015 , as compared to 90 in the corresponding period in 2014 , an increase of 13 % . we expect our subscription revenue will continue to increase as a result of our shift to a cloud-first strategy . maintenance and support . maintenance and support revenue increased $ 9.0 million to $ 63.7 million for the year ended december 31 , 2015 from $ 54.6 million for the year ended december 31 , 2014 , representing a 17 % increase . the increase in maintenance and support revenue was principally a result of an increase in the number of customers purchasing maintenance and support services related to their licensing of our software . we expect our maintenance revenue growth will decrease as a result of customers licensing less of our software as we shift to a cloud-first strategy . 33 cost of revenue and gross profit . replace_table_token_6_th cost of license . cost of license primarily consists of third-party fees for licenses . cost of license increased $ 0.1 million for the year ended december 31 , 2015 to $ 0.3 million from $ 0.2 million for the year ended december 31 , 2014 , representing a 25 % increase . license gross profit percentages for the year ended december 31 , 2015 and 2014 , remained relatively unchanged as a result of limited third-party fees for licensed software incurred over both periods . cost of services . cost of services decreased $ 3.8 million to $ 36.1 million for the year ended december 31 , 2015 from $ 40.0 million for the year ended december 31 , 2014 , representing a 10 % decrease . the decrease was primarily attributable to a decrease in personnel costs used in our software implementations of $ 2.6 million and a decrease in other overhead expenses of $ 1.2 million . services gross profit percentages for the years ended december 31 , 2015 and 2014 , were 16 % and 19 % , respectively . the percent decrease in services gross profit was primarily driven by the completion of several implementations in 2014 with higher professional services man-day rates and lower professional services utilization during the year ended december 31 , 2015 . service gross profit percentages can vary from period to period depending on different factors , including the level of professional services required to implement our software and the utilization of our professional services personnel . cost of subscription . cost of subscription increased $ 5.5 million to $ 12.8 million for the year ended december 31 , 2015 from $ 7.3 million for the year ended december 31 , 2014 , representing a 74 % increase . the increase was primarily attributable to a $ 2.6 million increase in personnel costs and a $ 2.9 million increase in infrastructure costs to support our current and anticipated future subscription customer base . our subscription gross profit percentage for the years ended december 31 , 2015 and 2014 , was 56 % and 69 % , respectively . cost of maintenance and support . cost of maintenance and support revenue increased $
