What is goodwill impairment testing under ASC 350?

ASC 350 (Intangibles — Goodwill and Other) requires companies to test goodwill for impairment at least annually (or more frequently if indicators of impairment exist). The test compares the fair value of a reporting unit to its carrying amount (book value including goodwill). If fair value < carrying amount, an impairment charge equals that difference (capped at the carrying amount of goodwill). The old two-step test was eliminated in 2017 (ASU 2017-04).

What are goodwill impairment triggers?

Goodwill impairment triggers under ASC 350-20-35-3C include: macroeconomic deterioration (recession, rising interest rates), industry/market decline affecting the reporting unit, reporting unit performance below projections, change in management or business strategy, sustained market cap decline below book value, and regulatory/legal factors. Companies must assess these qualitative factors (Step 0) and perform the quantitative test if triggering events are identified or if qualitative assessment suggests impairment is more likely than not.

How is fair value of a reporting unit determined?

Fair value of a reporting unit is typically estimated using the income approach (DCF of projected cash flows at an appropriate WACC) and/or the market approach (EV/EBITDA multiples from publicly traded guideline companies). The income approach is most common and defensible. The market approach provides a market check. The selected fair value is compared to the reporting unit's carrying amount (total assets minus total liabilities attributable to that unit, plus goodwill).

Goodwill Impairment Testing and AI

Goodwill impairment is one of the most judgement-intensive areas of financial reporting. Management must estimate the fair value of reporting units using DCF analysis, select appropriate comparable company multiples, assess qualitative triggering events, and document the analysis in a form that withstands external auditor scrutiny. Claude with ClaudeFinLab structures the impairment testing framework, builds the DCF model, selects guideline companies, and drafts the accounting documentation.

Qualitative Assessment (Step 0)

"Perform the Step 0 qualitative assessment for our 3 reporting units. Economic and industry factors: (1) the Fed raised rates from 0% to 5.25% (increases WACC, reduces DCF fair values); (2) our industrial segment's end market (construction) declined 18% in the period; (3) our software segment grew 12% (above plan). Company-specific factors: (1) industrial RU revenue missed plan by 22%; (2) we replaced the Industrial RU president in Q3; (3) market cap is $1.8B vs total book value $2.1B (cap discount to book). Assess each RU: is it more likely than not that fair value < carrying amount? Document the qualitative assessment per ASC 350-20-35-3C."
"Identify which qualitative factors are most significant for impairment risk: the industrial reporting unit shows 7 of the 15 standard impairment indicators per ASC 350. The combination of market cap below book, 22% revenue miss, and sustained margin compression creates a more likely than not conclusion requiring the quantitative test. Draft the audit committee memo documenting the Step 0 conclusion and the basis for proceeding to Step 1."

Quantitative Test: DCF Fair Value

"Build the DCF for the Industrial reporting unit: LTM revenue $285M, LTM EBITDA $38M (13.3% margin). 5-year forecast: Year 1 revenue $278M (market decline -2.5%), Year 2-5 recovery to 3% annual growth. EBITDA margin: Year 1 11.5% (restructuring), Year 2-5 recovery to 13.5%. Capex 4.5% of revenue. NWC change tied to revenue. WACC: 11.2% (rate increase impact on beta and cost of equity). Terminal growth rate: 2.0%. Compute DCF enterprise value."
"Compute the impairment charge: DCF fair value of industrial RU = $298M. Market approach (EV/EBITDA 7.5x on LTM EBITDA $38M): $285M. Selected fair value: $290M (weighted 70% income / 30% market). Carrying amount of industrial RU: total assets $385M - total liabilities $62M + goodwill $85M = $408M. Impairment: $408M - $290M = $118M — exceeds goodwill of $85M. Impairment charge = $85M (capped at goodwill balance). EPS impact, tax effect (deductible vs non-deductible goodwill — non-deductible: $0 tax benefit), and disclosure requirements."

WACC for Impairment Testing

"Compute the WACC for the industrial reporting unit impairment test: Risk-free rate: 4.65% (10-year UST). Equity risk premium: 5.5% (Duff & Phelps 2024). Beta: 1.15 (industry levered beta, re-levered for subject unit capital structure). Size premium: 1.8% (small reporting unit premium). Specific risk premium: 1.5% (customer concentration, key man risk). Cost of equity: 4.65% + (5.5% × 1.15) + 1.8% + 1.5% = 14.275%. Pre-tax cost of debt: 7.2%. Tax rate: 24%. Capital structure: 75% equity, 25% debt. WACC: 11.8%. Assess reasonableness vs prior year (prior year WACC 9.4% — 240bps increase, explain why)."

Market Approach and Guideline Companies

"Select guideline companies for the market approach: the industrial reporting unit manufactures precision metal components for automotive and aerospace OEMs (revenue $285M, EBITDA margin 13.3%). Potential guideline companies: [list 8 industrial manufacturing companies]. Screen for similarity: SIC code match, revenue range $150M-$1.5B, EBITDA margin 8%-20%, end market exposure. Recommend 5 guideline companies with rationale. Compute EV/EBITDA and EV/EBIT for each from recent trading data. Select the appropriate multiple range and justify the selection."

Documentation and Disclosure

"Draft the footnote disclosure for the $85M goodwill impairment charge: per ASC 350-20-50-2, the disclosure must include: (a) description of the reporting unit impaired; (b) facts and circumstances leading to impairment; (c) amount of impairment loss and how fair value was determined; (d) if the quantitative test was not performed for other reporting units, that conclusion; (e) cumulative amount of impairment. Draft the full footnote in SEC-style disclosure language."
"Draft the MD&A narrative for the impairment: the industrial segment recorded a $85M non-cash goodwill impairment charge in Q3 2025. Explain: (1) what drove the impairment (industry decline, rate environment, revenue miss); (2) the accounting methodology; (3) non-cash nature and no impact on covenant compliance; (4) management's outlook for the segment. Write 2 paragraphs in MD&A style (factual, forward-looking with safe harbor, investor-focused)."
