Amortization of Purchased Intangibles

The systematic write-down of the value of intangible assets acquired through business acquisitions over their useful lives.

Amortization of Purchased Intangibles is an accounting process where the cost of acquired non-physical assets—such as patents, customer lists, trademarks, and proprietary technology—is gradually expensed over time. This occurs after one company acquires another and allocates a portion of the purchase price to these specific intangible assets on the balance sheet, rather than lumping everything into non-amortizable goodwill. Because this is a non-cash expense resulting from historical mergers and acquisitions (M&A), companies frequently add it back when calculating non-GAAP operating income, adjusted EBITDA, and adjusted EPS. This adjustment helps analysts compare the core operational performance of different companies without the distortion of historical acquisition accounting. Investors should monitor this metric to understand the gap between GAAP and non-GAAP earnings. While it is a non-cash item, it reflects the ongoing consumption or obsolescence of assets that the company paid real capital to acquire. Relying solely on adjusted metrics that exclude this amortization can cause an investor to underestimate the true capital costs of an acquisition-heavy business strategy.

Company A acquires a competitor for $1,000,000,000 and allocates $100,000,000 of the purchase price to 'acquired technology' with an estimated useful life of 5 years. The annual amortization expense is calculated as $100,000,000 / 5, resulting in $20,000,000 of amortization of purchased intangibles recorded each year for the next 5 years.
