32 we also regularly evaluate acquisitions or investment opportunities in complementary businesses , joint ventures , services and technologies and intellectual property rights in an effort to expand our service offerings . we expect to continue to make such investments and acquisitions in the future and we plan to reinvest a significant portion of our incremental revenue in future periods to grow our business and continue our leadership role in the cloud computing industry . as a result of our aggressive growth plans , specifically our hiring plan and acquisition activities , we have incurred significant expenses from equity awards and amortization of purchased intangibles which have resulted in net losses on a u.s. generally accepted accounting principles ( `` gaap `` ) basis . as we continue with our growth plan , we may continue to have net losses on a gaap basis in some future quarters . we remained focused on improving operating margins in fiscal 2016 and expect to remain similarly focused in fiscal 2017. our operating margin for fiscal 2016 was $ 114.9 million compared to a $ 145.6 million loss during the same period a year ago . our typical subscription contract term is 12 to 36 months , although terms range from one to 60 months , so during any fiscal reporting period only a subset of active subscription contracts is eligible for renewal . we calculate our attrition rate as of the end of each month . our current attrition rate calculation does not include the marketing cloud service offerings . our attrition rate was between eight and nine percent during the fiscal year ended january 31 , 2016 , which is favorable compared to the nine to ten percent attrition rate as of january 31 , 2015 . we expect our attrition rate to remain in this range as we continue to expand our enterprise business and invest in customer success and related programs . we expect marketing and sales costs , which were 49 percent of our total revenues for the fiscal year ended january 31 , 2016 and 51 percent for the same period a year ago , to continue to represent a substantial portion of total revenues in the future as we seek to grow our customer base , sell more products to existing customers , and build greater brand awareness . fiscal year our fiscal year ends on january 31. references to fiscal 2016 , for example , refer to the fiscal year ending january 31 , 2016 . operating segments we operate as one operating segment . operating segments are defined as components of an enterprise for which separate financial information is evaluated regularly by the chief operating decision maker , who in our case is the chief executive officer , in deciding how to allocate resources and assess performance . over the past few years , we have completed several acquisitions . these acquisitions have allowed us to expand our offerings , presence and reach in various market segments of the enterprise cloud computing market . while we have offerings in multiple enterprise cloud computing market segments , our business operates in one operating segment because all of our offerings operate on a single platform and are deployed in an identical way , and our chief operating decision maker evaluates our financial information and resources and assesses the performance of these resources on a consolidated basis . since we operate as one operating segment , all required financial segment information can be found in the consolidated financial statements . sources of revenues we derive our revenues from two sources : ( 1 ) subscription revenues , which are comprised of subscription fees from customers accessing our enterprise cloud computing services and from customers paying for additional support beyond the standard support that is included in the basic subscription fees ; and ( 2 ) related professional services such as process mapping , project management , implementation services and other revenue . “ other revenue ” consists primarily of training fees . subscription and support revenues accounted for approximately 93 percent of our total revenues for fiscal 2016 . subscription revenues are driven primarily by the number of paying subscribers , varying service types , the price of our service and renewals . we define a “ customer ” as a separate and distinct buying entity ( e.g . , a company , a distinct business unit of a large corporation , a partnership , etc . ) that has entered into a contract to access our enterprise cloud computing services . we define a “ subscription ” as a unique user account purchased by a customer for use by its employees or other customer-authorized users , and we refer to each such user as a “ subscriber . ” the number of paying subscriptions at each of our customers ranges from one to hundreds of thousands . none of our customers accounted for more than five percent of our revenues during fiscal 2016 , 2015 or 2014 . subscription and support revenues are recognized ratably over the contract terms beginning on the commencement dates of each contract . the typical subscription and support term is 12 to 36 months , although terms range from one to 60 months . our subscription and support contracts are non-cancelable , though customers typically have the right to terminate their contracts for cause if we materially fail to perform . we generally invoice our customers in advance , in annual installments , and typical payment terms provide that our customers pay us within 30 days of invoice . amounts that have been invoiced are recorded in accounts receivable and in deferred revenue , or in revenue depending on whether the revenue recognition criteria have been met . in general , we collect our billings in advance of the subscription service period . 33 professional services and other revenues consist of fees associated with consulting and implementation services and training . story_separator_special_tag multiple deliverables included in an arrangement are separated into different units of accounting and the arrangement consideration is allocated to the identified separate units based on a relative selling price hierarchy . we determine the relative selling price for a deliverable based on its vendor-specific objective evidence of selling price ( “ vsoe ” ) , if available , or our best estimate of selling price ( “ besp ” ) , if vsoe is not available . we have determined that third-party evidence ( “ tpe ” ) is not a practical alternative due to differences in our service offerings compared to other parties and the availability of relevant third-party pricing information . the amount of revenue allocated to delivered items is limited by contingent revenue , if any . for certain professional services , we have established vsoe as a consistent number of standalone sales of this deliverable have been priced within a reasonably narrow range . we have not established vsoe for our subscription services due to lack of pricing consistency , the introduction of new services and other factors . accordingly , we use our besp to determine the relative selling price . we determined besp by considering our overall pricing objectives and market conditions . significant pricing practices taken into consideration include our discounting practices , the size and volume of our transactions , the customer demographic , the geographic area where our services are sold , our price lists , our go-to-market strategy , historical standalone sales and contract prices . the determination of besp is made through consultation with and approval by management , taking into consideration the go-to-market strategy . as our go-to-market strategies evolve , we may modify our pricing practices in the future , which could result in changes in relative selling prices , including both vsoe and besp . deferred revenue . the deferred revenue balance does not represent the total contract value of annual or multi-year , non-cancelable subscription agreements . deferred revenue primarily consists of billings or payments received in advance of revenue recognition from subscription services described above and is recognized as the revenue recognition criteria are met . we generally invoice customers in annual installments . the deferred revenue balance is influenced by several factors , including seasonality , the compounding effects of renewals , invoice duration , invoice timing , size and new business linearity within the quarter . deferred revenue that will be recognized during the succeeding twelve month period is recorded as current deferred revenue and the remaining portion is recorded as noncurrent . deferred commissions . we defer commission payments to our direct sales force . the commissions are deferred and amortized to sales expense over the non-cancelable terms of the related subscription contracts with our customers , which are typically 12 to 36 months . the commission payments , which are paid in full the month after the customer 's service commences , are a direct and incremental cost of the revenue arrangements . the deferred commission amounts are recoverable through the future revenue streams under the non-cancelable customer contracts . we believe this is the preferable method of accounting as the commission charges are so closely related to the revenue from the non-cancelable customer contracts that they should be recorded as an asset and charged to expense over the same period that the subscription revenue is recognized . during fiscal 2016 , we deferred $ 380.0 million of commission expenditures and we amortized $ 319.1 million to sales expense . during the same period a year ago , we deferred $ 320.9 million of commission expenditures and we amortized $ 257.6 38 million to sales expense . deferred commissions on our consolidated balance sheets totaled $ 449.1 million at january 31 , 2016 and $ 388.2 million at january 31 , 2015 . capitalized internal-use software costs . we are required to follow the guidance of accounting standards codification 350 ( “ asc 350 ” ) , intangibles- goodwill and other in accounting for the cost of computer software developed for internal-use and the accounting for web-based product development costs . asc 350 requires companies to capitalize qualifying computer software costs , which are incurred during the application development stage , and amortize these costs on a straight-line basis over the estimated useful life of the respective asset . we deliver our enterprise cloud computing solutions as a service via all the major internet browsers and on leading major mobile device operating systems . as a result of this software as a service delivery model , we believe we have larger capitalized costs as compared to traditional enterprise software companies as they are required to use a different accounting standard . costs related to preliminary project activities and post implementation activities are expensed as incurred . internal-use software is amortized on a straight-line basis over its estimated useful life . we evaluate the useful lives of these assets on an annual basis and test for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets . business combinations . accounting for business combinations requires us to make significant estimates and assumptions , especially at the acquisition date with respect to tangible and intangible assets acquired and liabilities assumed and pre-acquisition contingencies . we use our best estimates and assumptions to accurately assign fair value to the tangible and intangible assets acquired and liabilities assumed at the acquisition date . examples of critical estimates in valuing certain of the intangible assets and goodwill we have acquired include but are not limited to : future expected cash flows from subscription and support contracts , professional services contracts , other customer contracts and acquired developed technologies and patents ; the acquired company 's trade name , trademark and existing customer relationship , as well as assumptions about the period of time the acquired trade name and trademark will continue to be used in our offerings ;

net cash provided by financing activities was $ 132.6 million during fiscal 2016 as compared to net cash used in financing activities of $ 310.5 million during the same period a year ago . net cash provided by financing activities during fiscal 2016 consisted primarily of $ 455.5 million from proceeds from equity plan offset by $ 82.3 million of principal payments on capital leases and $ 300.0 million payment of our revolving credit facility . net cash flows used in financing activities during fiscal 2015 changed $ 443.1 million from the same period a year ago primarily due to $ 568.9 million payment on convertible senior notes , $ 285.0 million payment on term loan , offset by $ 297.3 million proceeds from revolving credit facility and $ 309.0 million of proceeds from our equity plans . in january 2010 , we issued $ 575.0 million of 0.75 % convertible senior notes due january 15 , 2015 ( the “ 0.75 % senior notes ” ) and concurrently entered into convertible notes hedges ( the “ 0.75 % note hedges ” ) and separate warrant transactions ( the “ 0.75 % warrants ” ) . on january 15 , 2015 , the 0.75 % senior notes matured . upon maturity of the 0.75 % senior notes , we delivered cash up to the remaining principal amount of the 0.75 % senior notes and shares of our common stock for the excess conversion value greater than the principal amount of the 0.75 % senior notes . as a result of the conversions and maturity of the 0.75 % senior notes during fiscal 2015 , the company exercised its rights on the 0.75 % note hedges , and the 0.75 % note hedges expired . additionally , in fiscal 2015 the company entered into agreements with each of the 0.75 % warrant counterparties to amend and settle the 0.75 % warrants prior to their scheduled expiration beginning in april 2015. as a result , the company issued , in the aggregate , approximately 13.3 million shares to the counterparties to settle , via a net share settlement , the entirety of the 0.75 % warrants .
