This document summarizes Accounting Standard 26 regarding intangible assets. It defines intangible assets as non-physical assets that provide future economic benefits and are controlled by an entity. Examples include goodwill, patents, trademarks and software. Intangible assets must be recognized initially at cost and amortized over their useful lives, generally 10 years or less. When an intangible asset is retired or disposed of, any gain or loss is recognized in the income statement. An impairment loss is recorded if an asset's recoverable amount falls below its carrying value. The document also distinguishes between tangible and intangible assets.
