we expect our product development , sales and marketing , and general and administrative expenses as a percentage of revenues to decrease over time as we grow our revenues , and we anticipate that we will gain economies of scale by increasing our customer base without direct incremental development costs and by utilizing more of the capacity of our data centers . since inception , we have invested heavily in our professional services organization to help ensure that customers successfully deploy and adopt our applications . additionally , we continue to expand our professional services partner ecosystem to further support our customers . we believe our investment in professional services , as well as partners building consulting practices around workday , will drive additional customer subscriptions and continued growth in revenues . in addition , over time we expect professional services revenues and the cost of professional services as a percentage of total revenues to decline as we increasingly rely on our partners to deploy workday applications and as the number of our existing customers continues to grow . 27 fiscal year end our fiscal year ends on january 31. references to fiscal 2015 , for example , refer to the year ended january 31 , 2015. components of results of operations revenues we primarily derive our revenues from subscription services fees and professional services fees . subscription services revenues primarily consist of fees that give our customers access to our cloud applications , which include routine customer support at no additional cost . professional services fees include deployment services , optimization services , and training . subscription services revenues accounted for over 78 % of our total revenues during fiscal 2015 and represented over 96 % of our total unearned revenue as of january 31 , 2015. subscription services revenues are driven primarily by the number of customers , the number of workers at each customer , the number of applications subscribed to by each customer , and the price of our applications . the mix of the applications to which a customer subscribes can affect our financial performance due to price differentials in our applications . compared to our other offerings , our hcm application has been available for a longer period of time , is more established in the marketplace and has benefited from continued enhancements of the functionality over a longer period of time , all of which help us to improve our pricing for that application . however , new products or services offerings by competitors in the future could impact the mix and pricing of our offerings . subscription services fees are recognized ratably as revenues over the contract term beginning on the date the application is made available to the customer , which is generally within one week of contract signing . our subscription contracts typically have a term of three years and are non-cancelable . we generally invoice our customers in advance , in annual installments . amounts that have been invoiced are initially recorded as unearned revenue . amounts that have not been invoiced represent backlog and are not reflected in our consolidated financial statements . the majority of our consulting engagements are billed on a time and materials basis , and revenues are typically recognized as the services are performed . we offer a number of training options intended to support our customers in configuring , using and administering our services . in some cases , we supplement our consulting teams by subcontracting resources from our service partners and deploying them on customer engagements . as workday 's professional services organization and the workday-related consulting practices of our partner firms continue to develop , we expect the partners to increasingly contract directly with our subscription customers . as a result of this trend , and the increase of our subscription services revenues , we expect professional services revenues as a percentage of total revenues to decline over time . costs and expenses costs of subscription services revenues . costs of subscription services revenues consist primarily of employee-related expenses related to hosting our applications and providing customer support , the costs of data center capacity , and depreciation of owned and leased computer equipment and software . costs of professional services revenues . costs of professional services revenues consist primarily of employee-related expenses associated with these services , the cost of subcontractors and travel . the percentage of total revenues derived from professional services was 22 % in fiscal 2015. the cost of providing professional services is significantly higher as a percentage of the related revenues than for our subscription services . product development . product development expenses consist primarily of employee-related costs . we continue to focus our product development efforts on adding new features and applications , increasing the functionality and enhancing the ease of use of our cloud applications . sales and marketing . sales and marketing expenses consist primarily of employee-related costs , sales commissions , marketing programs and travel . marketing programs consist of advertising , events , corporate communications , brand building and product marketing activities . commissions earned by our sales force that can be associated specifically with a non-cancelable subscription contract are deferred and amortized over the same period that revenues are recognized for the related non-cancelable contract . 28 general and administrative . general and administrative expenses consist of employee-related costs for finance and accounting , legal , human resources and management information systems personnel , legal costs , professional fees and other corporate expenses . results of operations revenues our total revenues for fiscal 2015 , 2014 and 2013 were as follows : replace_table_token_7_th fiscal 2015 compared to fiscal 2014. total revenues were $ 788 million for fiscal 2015 , compared to $ 469 million for fiscal 2014 , an increase of $ 319 million , or 68 % . story_separator_special_tag this grant resulted in a one-time charge of $ 11 million , which was recorded to the general and administrative expenses line of the consolidated statements of operations . we do not expect to make future grants of shares to the workday foundation and therefore consider this charge as non-recurring . as such , we believe it is useful to exclude this one-time charge in order to better understand the ongoing expenses of our core business and to facilitate comparison of our results across periods . free cash flows we define free cash flows as net cash provided by operating activities minus purchases of property and equipment , property and equipment acquired under capital leases and purchases of other ( non-acquisition-related ) intangible assets . we use free cash flows as a measure of financial progress in our business , as it balances operating results , cash management and capital efficiency . when calculating free cash flows , we subtract the gross value of all equipment acquired in the period , even when acquired under capital leases , so that we can evaluate our progress on free cash flows independent of our capital financing decisions . we believe information regarding free cash flows provides investors and others with an important perspective on the cash available to make strategic acquisitions and investments , to fund ongoing operations and to fund other capital expenditures . limitations on the use of non-gaap financial measures a limitation of our non-gaap financial measures of core operating expenses , core operating margin and free cash flows is that they do not have uniform definitions . our definitions will likely differ from the definitions used by other companies , including peer companies , and therefore comparability may be limited . in addition , other peer companies may not publish these or similar metrics . thus , our non-gaap measures of core operating expenses , core operating margin and free cash flows should be considered in addition to , not as a substitute for , or in isolation from , measures prepared in accordance with gaap . additionally , in the case of share-based compensation , if we did not pay out a portion of compensation in the form of share-based compensation and related employer payroll tax-related items , the cash salary expense included in costs of revenues and operating expenses would be higher , which would affect our cash position . further , the non-gaap measure of core operating expenses has certain limitations because it does not reflect all items of income and expense that affect our operations and are reflected in the gaap measure of total operating expenses . we compensate for these limitations by reconciling core operating expenses to the most comparable gaap financial measure and reviewing these measures in conjunction with gaap financial information . we encourage investors and others to review our financial information in its entirety , not to rely on any single financial measure and to view our non-gaap financial measures in conjunction with the most comparable gaap financial measures . see “ results of operations—core operating expenses ” for a reconciliation of the non-gaap financial measure of core operating expenses to the most comparable gaap measure , “ total operating expenses , ” for fiscal 2015 , 2014 and 2013. see “ liquidity and capital resources ” for a reconciliation of free cash flows to the most comparable gaap measure , “ net cash provided by ( used in ) operating activities , ” for fiscal 2015 , 2014 and 2013 . 35 backlog we generally sign multiple-year subscription contracts for our applications . the timing of our invoices to the customer is a negotiated term and varies among our subscription contracts . for multiple-year agreements , it is common to invoice an initial amount at contract signing followed by subsequent annual invoices . at any point in the contract term , there can be amounts that we have not yet been contractually able to invoice . until such time as these amounts are invoiced , they are not recorded in revenues , unearned revenue or elsewhere in our consolidated financial statements . to the extent future invoicing is determined to be certain , we consider those future subscription invoices to be non-cancelable backlog . future invoicing is determined to be certain when we have a fully executed non-cancelable contract and invoicing is not dependent on a future event such as customer funding or the delivery of a product . the amount of non-cancelable subscription contract backlog was $ 965 million as of january 31 , 2015. we expect that the amount of backlog relative to the total value of our contracts will change from year to year for several reasons , including the amount of cash collected early in the contract term , the specific timing and duration of large customer subscription agreements , varying invoicing cycles of subscription agreements , the specific timing of customer renewals , changes in customer financial circumstances and foreign currency fluctuations . backlog may also vary based on changes in the average non-cancelable term of our subscription agreements . accordingly , we believe that fluctuations in backlog are not a reliable indicator of future revenues and we do not utilize backlog as a key management metric internally . contractual obligations the following table summarizes our consolidated principal contractual cash obligations as of january 31 , 2015 : replace_table_token_13_th ( 1 ) represents aggregate principal amount of the notes , without the effect of associated discounts . ( 2 ) represents estimated aggregate interest obligations for our outstanding notes that are payable in cash . ( 3 ) includes principal and imputed interest . ( 4 ) for the 95-year lease we entered in january 2013 , the cash obligations exclude the potential annual rental increases based on the increases to the consumer price index ( cpi ) . ( see more information under “ commitments ” below ) . we expect to make

liquidity and capital resources as of january 31 , 2015 , our principal sources of liquidity were cash , cash equivalents and marketable securities totaling $ 1.9 billion , which were held for working capital purposes . our cash equivalents and marketable securities are composed primarily of u.s. agency obligations , u.s. treasury securities , u.s. corporate securities , commercial paper , and money market funds . we have financed our operations primarily through sales of equity securities , customer payments , and issuance of debt . our future capital requirements will depend on many factors , including our customer growth rate , subscription renewal activity , the timing and extent of development efforts , the expansion of sales and marketing activities , the introduction of new and enhanced services offerings , and the continuing market acceptance of our services . we may in the future enter into arrangements to acquire or invest in complementary businesses , services and technologies , and intellectual property rights . we may choose to seek additional equity or debt financing . our cash flows for fiscal 2015 , 2014 and 2013 were as follows : replace_table_token_11_th in evaluating our performance internally , we focus on long-term , sustainable growth in free cash flows . we define free cash flows , a non-gaap financial measure , as net cash provided by ( used in ) operating activities minus purchases of property and equipment , property and equipment acquired under capital leases and purchases of other ( non-acquisition-related ) intangible assets . see “ non-gaap financial measures ” below for further information . our free cash flows for fiscal 2015 , 2014 and 2013 were as follows : replace_table_token_12_th operating activities we use cash provided by operating activities as a key financial metric . cash provided by operating activities was $ 102 million , $ 46 million and $ 11 million , respectively , for fiscal 2015 , 2014 and 2013. the increase in cash flows compared to prior fiscal years resulted primarily from increased cash collections driven by growth in customer demand for our services .
