we generally bill maintenance fees annually in advance and recognize the resulting revenues ratably over the term of the maintenance agreement . we derive revenues from services which primarily include consulting , implementation , training , software as a service ( saas ) , hosting and managed services . we bill for these services primarily under time and materials arrangements and recognize fees as we perform the services . deferred revenues represent advance payments or billings for software licenses , services , and maintenance billed in advance of the time we recognize revenues . we record revenues from sales of third-party products in accordance with principal agent considerations within the revenue recognition topic of the fasb accounting standards codification . furthermore , we evaluate sales through our indirect channel on a case-by-case basis to determine whether the transaction should be recorded gross or net , including but not limited to assessing

returns , and ( 4 ) act as an agent or broker with compensation on a commission or fee basis . accordingly , our sales through the dmi channel are typically recorded on a gross basis . generally , our software products do not require significant modification or customization . installation of the products is routine and is not essential to their functionality . our sales frequently include maintenance contracts and professional services with the sale of our software licenses . we have established vsoe for our maintenance contracts and professional services . we determine fair value based upon the prices we charge to customers when we sell these elements separately . we defer maintenance revenues , including those sold with the initial license fee , based on vsoe , and recognize the revenue ratably over the maintenance contract period . we recognize consulting and training service revenues , including those sold with license fees , as we perform the services based on their 43

the customer has no ability to take delivery of the software , and the underlying arrangements typically include a single fee for the service that is billed monthly , quarterly or annually . stock-based compensation . we estimate the value of options granted on the date of grant using the black-scholes option pricing model . management judgments and assumptions related to volatility , the

assets and liabilities and any valuation allowance to be recorded against our net deferred tax asset . our judgments , assumptions and estimates relative to the current provision for income tax take into account current tax laws , our interpretation of current tax laws , allowable deductions , tax planning strategies , projected tax credits and possible outcomes of current and future audits conducted by foreign and domestic tax authorities . changes in tax laws or our interpretation of tax laws and the resolution of current and future tax audits could significantly impact the amounts provided for income taxes in our financial position and results of operations . our assumptions , judgments and estimates relative to the value of our deferred tax asset take into account our expectations of the amount and category of future taxable income . actual operating results and the underlying amount and category of income in future years , which could significantly increase tax expense , could render inaccurate our current assumptions , judgments and estimates of recoverable net deferred taxes . business combinations and intangible assets including goodwill . we account for business combinations using the acquisition method of accounting and accordingly , the identifiable assets acquired and liabilities assumed are recorded based upon management 's estimates of current fair values as of the acquisition date . the estimation process includes analyses based on income and market approaches . goodwill represents the excess purchase price over the fair value of net assets , including the amount assigned to identifiable intangible assets . the goodwill generated is due in part to the synergies that are not included in the fair value of identifiable intangible assets . goodwill recorded in an acquisition is assigned to applicable reporting units based on expected revenues . identifiable intangible assets with finite lives are amortized over there useful lives . amortization of current technology is recorded in cost of revenues-license and amortization of all other intangible assets is recorded in amortization of acquisition-related intangibles .

year ended april 30 , 2018 increased to 56 % in fiscal 2018 when compared to 52 % in fiscal 2017 due to the increase in gross margin percentage for license fees margins , services and other gross margins and maintenance gross margin . the total gross margin percentage for the year ended april 30 , 2017 was primarily the same as the prior fiscal year due to the increase in gross margin percentage on services and other gross margins . this was partially offset by a decrease in license fees margins when compared to the prior year . gross margin on license fees the increase in license

amortization expense to increase in fiscal 2019 when compared to fiscal 2018. the decrease in license fee gross margin percentage for the year ended april 30 , 2017 when compared to fiscal 2016 was primarily due to the 29 % decrease in license fees in fiscal 2017 when compared to the prior year . license fee gross margin percentage tends to be directly related to the level of license fee
