An asset (typically a financial asset/ intangible asset) that is subject to an amortization scheme whereby its amortized cost is allocated or expensed over the course of its lifespan or useful life. The asset’s cost or principal amount (capital value) is written off usually over regular intervals, with the amount written off being incrementally charged to an expense account. By nature, amortizable assets do not have a salvage value (contrary to depreciable assets) and amortization of such assets is implemented using the straight-line method (as opposed to depreciable assets, for which many methods can be used in addition to straight lining.)

Examples of assets that are expensed through amortization include debt securities, patents and trademarks, franchises, etc.
