Expense allocation
Intangible assets are typically expensed according to their respective life expectancy. Intangible assets have either an identifiable or an indefinite useful life. Intangible assets with identifiable useful lives are amortized on a straight-line basis over their economic or legal life, whichever is shorter. Examples of intangible assets with identifiable useful lives are copyrights and patents. Intangible assets with indefinite useful lives are reassessed each year for impairment. If an impairment has occurred, then a loss must be recognized. An impairment loss is determined by subtracting the asset's fair value from the asset's book/carrying value. Trademarks and goodwill are examples of intangible assets with indefinite useful lives. Goodwill has to be tested for impairment rather than amortized. If impaired, goodwill is reduced and loss is recognized in the Income statement.
