Current accounting standards suggest categories of intangible assets for possible recognition when one business acquires another. Examples include noncompetition agreements, customer lists, patents, subscriber lists, databases, trademarks, lease agreements, licenses, and many others. All identified intangible assets should be amortized over their economic useful life unless such life is considered indefinite. The term indefinite life is defined as a life that extends beyond the foreseeable future. A recognized intangible asset with an indefinite life should not be amortized unless and until its life is determined to be finite. Importantly, indefinite does not mean "infinite. " Also, the useful life of an intangible asset should not be considered indefinite because a precise finite life is not known.
