adobe systems incorporated notes to consolidated financial statements ( continued ) foreign currency translation we translate assets and liabilities of foreign subsidiaries , whose functional currency is their local currency , at exchange rates in effect at the balance sheet date .
we translate revenue and expenses at the monthly average exchange rates .
we include accumulated net translation adjustments in stockholders 2019 equity as a component of accumulated other comprehensive income .
property and equipment we record property and equipment at cost less accumulated depreciation and amortization .
property and equipment are depreciated using the straight-line method over their estimated useful lives ranging from 1 to 5 years for computers and equipment , 1 to 6 years for furniture and fixtures and up to 35 years for buildings .
leasehold improvements are amortized using the straight-line method over the lesser of the remaining respective lease term or useful lives .
goodwill , purchased intangibles and other long-lived assets we review our goodwill for impairment annually , or more frequently , if facts and circumstances warrant a review .
we completed our annual impairment test in the second quarter of fiscal 2009 and determined that there was no impairment .
goodwill is assigned to one or more reporting segments on the date of acquisition .
we evaluate goodwill for impairment by comparing the fair value of each of our reporting segments to its carrying value , including the associated goodwill .
to determine the fair values , we use the market approach based on comparable publicly traded companies in similar lines of businesses and the income approach based on estimated discounted future cash flows .
our cash flow assumptions consider historical and forecasted revenue , operating costs and other relevant factors .
we amortize intangible assets with finite lives over their estimated useful lives and review them for impairment whenever an impairment indicator exists .
we continually monitor events and changes in circumstances that could indicate carrying amounts of our long-lived assets , including our intangible assets may not be recoverable .
when such events or changes in circumstances occur , we assess recoverability by determining whether the carrying value of such assets will be recovered through the undiscounted expected future cash flows .
if the future undiscounted cash flows are less than the carrying amount of these assets , we recognize an impairment loss based on the excess of the carrying amount over the fair value of the assets .
we did not recognize any intangible asset impairment charges in fiscal 2009 , 2008 or 2007 .
our intangible assets are amortized over their estimated useful lives of 1 to 13 years as shown in the table below .
amortization is based on the pattern in which the economic benefits of the intangible asset will be consumed .

software development costs capitalization of software development costs for software to be sold , leased , or otherwise marketed begins upon the establishment of technological feasibility , which is generally the completion of a working prototype that has been certified as having no critical bugs and is a release candidate .
amortization begins once the software is ready for its intended use , generally based on the pattern in which the economic benefits will be consumed .
to date , software development costs incurred between completion of a working prototype and general availability of the related product have not been material .
revenue recognition our revenue is derived from the licensing of software products , consulting , hosting services and maintenance and support .
primarily , we recognize revenue when persuasive evidence of an arrangement exists , we have delivered the product or performed the service , the fee is fixed or determinable and collection is probable. .
