pre_text: nbcuniversal media , llc indefinite-lived intangible assets indefinite-lived intangible assets consist of trade names and fcc licenses . we assess the recoverability of our indefinite-lived intangible assets annually , or more frequently whenever events or substantive changes in circumstances indicate that the assets might be impaired . we evaluate the unit of account used to test for impairment of our indefinite-lived intangible assets periodically or whenever events or substantive changes in circumstances occur to ensure impairment testing is performed at an appropriate level . the assessment of recoverability may first consider qualitative factors to determine whether it is more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying amount . a quantitative assessment is per- formed if the qualitative assessment results in a more-likely-than-not determination or if a qualitative assessment is not performed . when performing a quantitative assessment , we estimate the fair value of our indefinite-lived intangible assets primarily based on a discounted cash flow analysis that involves significant judgment . when analyzing the fair values indicated under the discounted cash flow models , we also consider multiples of operating income before depreciation and amortization generated by the underlying assets , cur- rent market transactions , and profitability information . if the fair value of our indefinite-lived intangible assets were less than the carrying amount , we would recognize an impairment charge for the difference between the estimated fair value and the carrying value of the assets . unless presented separately , the impairment charge is included as a component of amortization expense . we did not recognize any material impairment charges in any of the periods presented . finite-lived intangible assets estimated amortization expense of finite-lived intangible assets ( in millions ) .
post_text: finite-lived intangible assets are subject to amortization and consist primarily of customer relationships acquired in business combinations , intellectual property rights and software . our finite-lived intangible assets are amortized primarily on a straight-line basis over their estimated useful life or the term of the associated agreement . we capitalize direct development costs associated with internal-use software , including external direct costs of material and services and payroll costs for employees devoting time to these software projects . we also capitalize costs associated with the purchase of software licenses . we include these costs in intangible assets and generally amortize them on a straight-line basis over a period not to exceed five years . we expense maintenance and training costs , as well as costs incurred during the preliminary stage of a project , as they are incurred . we capitalize initial operating system software costs and amortize them over the life of the associated hardware . we evaluate the recoverability of our finite-lived intangible assets whenever events or substantive changes in circumstances indicate that the carrying amount may not be recoverable . the evaluation is based on the cash flows generated by the underlying asset groups , including estimated future operating results , trends or other determinants of fair value . if the total of the expected future undiscounted cash flows were less than the carry- ing amount of the asset group , we would recognize an impairment charge to the extent the carrying amount of the asset group exceeded its estimated fair value . unless presented separately , the impairment charge is included as a component of amortization expense . comcast 2015 annual report on form 10-k 162 .
