ASC 350 Indefinite-Lived Intangibles — Core Rule
Under ASC 350 Indefinite-Lived Intangibles, an intangible asset with an indefinite useful life must be tested for impairment at least annually — and more frequently if triggering events exist — by comparing the asset's fair value to its carrying amount, with any excess of carrying amount over fair value recognized as an impairment loss.
How ASC 350 Indefinite-Lived Intangibles Works
- Scope and frequency: ASC 350-30-35-18 requires annual impairment testing for indefinite-lived intangible assets (e.g., trade names, trademarks, broadcast licenses, certain franchise rights) at the same time each year. Unlike finite-lived intangibles, these assets are not amortized, making impairment testing the primary carrying-value discipline.
- Optional qualitative assessment ("Step 0"): Per ASC 350-30-35-18A through 18C, an entity may first perform a qualitative assessment to determine whether it is more likely than not (i.e., likelihood > 50%) that the fair value of the intangible asset is less than its carrying amount. Relevant factors include macroeconomic conditions, industry trends, cost factors, financial performance, and entity-specific events. If the qualitative conclusion is that impairment is unlikely, no further testing is required.
- Quantitative impairment test: If the qualitative screen is failed — or if the entity elects to skip it — ASC 350-30-35-19 mandates a quantitative test: compare the asset's fair value (typically determined under ASC 820 using the relief-from-royalty method or multi-period excess earnings method) to its carrying amount. If carrying amount exceeds fair value, an impairment charge equals that difference.
- Measurement of impairment loss: Under ASC 350-30-35-20, the impairment loss is measured as the amount by which the carrying amount exceeds fair value. There is no floor other than zero — the asset can be written down to zero if fair value is zero. The loss is reported within continuing operations on the income statement.
- No reversal of impairment: Once recognized, an impairment loss on an indefinite-lived intangible asset cannot be reversed under US GAAP, even if conditions improve (contrast with IAS 36 under IFRS, which permits reversals). This creates a permanently reduced cost basis.
- Disclosure requirements: ASC 350-30-50-3 requires disclosure of the gross carrying amount, accumulated impairment losses (tracked separately from accumulated amortization), and a description of impaired assets, the facts and circumstances leading to impairment, and the fair value measurement methodology used.
ASC 350 Indefinite-Lived Intangibles — Practical Example
Assume a company holds a trade name with a carrying amount of $5,000,000. Annual impairment testing using the relief-from-royalty method yields a fair value of $3,800,000. The impairment loss is $1,200,000 ($5,000,000 − $3,800,000).
Journal entry to record impairment
| Account | Dr | Cr |
|---|
| Impairment Loss — Trade Name | $1,200,000 | |
| Accumulated Impairment Loss — Trade Name | | $1,200,000 |
The trade name now carries a net book value of $3,800,000 on the balance sheet. In subsequent periods, the $3,800,000 becomes the new cost basis for impairment testing — not the original $5,000,000.
If, next year, fair value recovers to $4,500,000, no reversal entry is permitted under US GAAP.
ASC 350 Indefinite-Lived Intangibles — Common Pitfalls
- Conflating the qualitative and quantitative thresholds: Practitioners sometimes treat a "more likely than not" qualitative pass as permanent protection. The qualitative assessment must be re-performed annually and does not carry forward. A triggering event mid-year (e.g., loss of a major license customer, regulatory change) requires an interim quantitative test regardless of the prior annual conclusion per ASC 350-30-35-18.
- Incorrect fair value methodology: The relief-from-royalty method requires supportable royalty rate benchmarks and appropriate discount rates under ASC 820. Using stale comparable transactions or ignoring tax amortization benefits (TAB) in the discount rate builds systematic undervaluation error into the fair value — a frequent audit finding.
- Misclassification of finite vs. indefinite-lived assets: An asset classified as indefinite-lived must genuinely have no foreseeable limit to the period over which it generates cash flows (ASC 350-30-35-4). Regulatory licenses subject to renewal conditions, or trade names tied to discontinuing product lines, often should be reclassified as finite-lived — triggering amortization prospectively and a separate impairment assessment at reclassification date per ASC 350-30-35-17.
