ASC 350 Intangibles and Goodwill — Core Rule

Goodwill must be tested for impairment annually (or when a triggering event occurs) by comparing the fair value of a reporting unit to its carrying amount; if carrying amount exceeds fair value, impairment loss is recognized equal to the excess (ASC 350-20-35-3C).


How ASC 350 Intangibles and Goodwill Works

  • Reporting unit identification: Goodwill is assigned to reporting units (operating segments or one level below) as defined in ASC 350-20-20. A reporting unit is the lowest level at which goodwill is monitored for internal reporting purposes. Management must clearly delineate these units before testing begins.
  • Annual testing requirement and timing: Under ASC 350-20-35-3C, goodwill is tested annually for impairment, with management selecting a consistent testing date each year (often the fiscal year-end, but any date is permissible). Testing must also occur when triggering events occur between annual tests (e.g., significant adverse changes in business climate, loss of key customers, restructuring, or fair value indicators suggesting impairment).
  • Fair value measurement of the reporting unit: ASC 350-20-30-1 and ASC 820 (Fair Value Measurement) require the fair value of the reporting unit to be determined using market approaches, income approaches (discounted cash flow), or cost approaches. Common methods include comparable company multiples (EBITDA, revenue), recent transactions, or DCF models. Management must assess whether to use a single valuation method or a weighted combination.
  • Impairment calculation (single-step method): Under ASC 350-20-35-3C, if the fair value of a reporting unit is less than its carrying amount (including goodwill and all identifiable assets and liabilities), goodwill impairment exists. The impairment loss recognized is the amount by which carrying amount exceeds fair value, but not to exceed the goodwill balance of that reporting unit. No interim recognition of implied fair value of goodwill is required.
  • Qualitative assessment option: ASC 350-20-35-3A permits entities to first perform a qualitative assessment to determine whether it is more likely than not (probability >50%) that the fair value of a reporting unit is less than its carrying amount. If this threshold is not met, quantitative testing can be bypassed. If the threshold is met or the entity foregoes the qualitative assessment, full quantitative impairment testing must follow.
  • Disclosure and documentation: ASC 350-20-50-1 and ASC 350-20-50-2 require disclosure of the valuation methods used, key assumptions (discount rates, growth rates, terminal values), and carrying amounts of goodwill by reporting unit. In the year of impairment, the loss must be prominently disclosed with causes and effects.

ASC 350 Intangibles and Goodwill — Practical Example

Scenario: A mid-market technology company acquired a software-as-a-service platform two years ago for $50 million, including $32 million in goodwill. The reporting unit now carries:
  • Goodwill: $32 million
  • Identifiable intangible assets: $12 million
  • Tangible net assets: $8 million
  • Total carrying amount: $52 million

During Year 3, customer churn accelerated, and contract renewal rates declined. Management triggers an impairment test using a DCF model.

DCF Valuation (Fair Value Calculation):

  • Projected cash flows (5 years): $8M, $7.5M, $7M, $6.5M, $6M
  • Terminal value (perpetuity growth 2%): $6M × 1.02 / (0.10 – 0.02) = $76.5M
  • Discount rate (WACC): 10%
  • PV of cash flows (Years 1–5): $30.2M
  • PV of terminal value: $52.1M
  • Fair value of reporting unit: $82.3M

Since fair value ($82.3M) exceeds carrying amount ($52M), no impairment is indicated. Testing is complete.

Alternative scenario: If the DCF had yielded a fair value of $48M:

  • Carrying amount: $52M
  • Fair value: $48M
  • Impairment loss: $4M (recognized against goodwill)

Dr. Goodwill Impairment Loss    $4,000,000
    Cr. Goodwill                             $4,000,000
(To record impairment of goodwill in the 
 SaaS platform reporting unit)

The goodwill balance would then be reduced from $32M to $28M on the balance sheet.


ASC 350 Intangibles and Goodwill — Common Pitfalls

  • Overstating fair value through aggressive assumptions: Practitioners often use revenue growth rates or terminal growth assumptions that are inconsistent with macroeconomic forecasts or peer performance. Auditors scrutinize DCF models heavily; ensure discount rates reflect market conditions (including equity risk premium, beta, and cost of debt) and growth rates are supported by historical performance and analyst consensus (ASC 820-10-35-24).
  • Misidentifying reporting units: Some entities fail to properly delineate reporting units or combine units that operate independently, masking impairment in stronger units. Each reporting unit must have discrete financial results monitored by management; improper grouping can delay or hide necessary write-downs and trigger audit adjustments.
  • Failing to recognize triggering events: Management sometimes defers qualitative or quantitative testing until year-end, missing interim triggering events (loss of major customers, regulatory changes, competitive pressure). ASC 350-20-35-3E requires testing when a triggering event occurs, and failure to test timely can result in delayed impairment recognition and restatement risk.
