Amortization (Accounting)

Amortization in accounting has two primary meanings. First, it refers to the systematic allocation of the cost of an intangible asset (such as patents, trademarks, copyrights, customer relationships, or goodwill from acquisitions) over its estimated useful life. This is the intangible asset equivalent of depreciation for tangible assets. Each period, an amortization expense is recorded on the income statement, and the carrying value of the intangible asset on the balance sheet decreases correspondingly. The second meaning relates to debt: loan amortization is the process of paying down a loan's principal through regular scheduled payments (as with a mortgage or car loan). In fundamental analysis, amortization is particularly important when evaluating companies that have made significant acquisitions — the amortization of acquired intangible assets can substantially reduce reported net income without representing a true economic cost or cash outflow. This is why many analysts prefer metrics like EBITDA or adjusted earnings that add back amortization of acquired intangibles. The distinction between amortizable intangible assets (finite-lived, like patents) and non-amortizable ones (indefinite-lived, like certain trademarks) is also important for financial modeling.
