Built versus bought: why treatment differs
Internally developed intangibles (like R&D) are expensed under U.S. GAAP and never appear on the balance sheet. Acquired intangibles are capitalized at purchase price. Two identical assets get wildly different treatment depending on whether they were built or bought.
Internally developed vs acquired intangibles
| Treatment | Internally Developed | Acquired |
|---|---|---|
| Balance Sheet | Not recognized (expensed as R&D) | Capitalized at fair value |
| Income Statement | R&D expense reduces current income | Amortized over useful life |
| Example | $800M drug development → expense | Same drug bought for $2B → asset |
| Impact on ROA | Lower assets → higher ROA | Higher assets → lower ROA |
How goodwill arises from an acquisition
Goodwill = Purchase Price − Fair Value of Net Identifiable Assets. It arises exclusively from acquisitions and represents synergies, brand value, and market position that cannot be individually identified.
Goodwill = Purchase Price − Fair Value of Net Identifiable Assets
Goodwill is never amortized under U.S. GAAP — it’s tested for impairment annually. Once written down, it can never be written back up. A goodwill impairment charge is management admitting an acquisition destroyed value.
| Intangible Type | Amortized? | Impairment Test |
|---|---|---|
| Goodwill | No — indefinite life | Annual (or if triggered) |
| Finite-life (patents, contracts) | Yes — over useful life | If triggering event occurs |
| Indefinite-life (trademarks) | No | Annual (like goodwill) |

What happens when an acquisition underperforms
Sit with the ideas.
A telecom company has $45B in total assets, of which $18B is goodwill from a decade of acquisitions. This year, it records a $6B goodwill impairment charge. Net income before the charge was $4B. What should an analyst conclude?
