Goodwill Impairment — Quantitative Fair-Value Testing Techniques

When qualitative analysis does not rule out impairment, entities must estimate the fair value of each reporting unit and compare it to its carrying amount.

If the carrying amount exceeds fair value, the difference is recognized as a goodwill impairment loss, subject to specific valuation assumptions and guidance under each framework.

1. When the quantitative test is required

The quantitative goodwill impairment test is required when:

• A Step 0 qualitative test indicates it is not more likely than not that the reporting unit’s fair value exceeds its carrying amount.

• The entity elects to bypass the Step 0 qualitative test.

• A triggering event (e.g., macroeconomic change, deterioration of performance, business reorganization) occurs during the year.

The test compares the fair value of the reporting unit (US GAAP) or CGU (IFRS) to its carrying amount, including allocated goodwill.

2. Calculating fair value of the reporting unit

Common valuation techniques include:

Approach	Description	Typical Use Case
Income approach	Discounted Cash Flow (DCF) model	Most widely used; captures future value
Market approach	Multiples of earnings, revenue, or EBITDA from peer companies	When market comparables are available
Cost approach	Reproduction or replacement cost	Rare for goodwill; used for asset-heavy units

Income approach is the most common and involves:

1. Projecting future cash flows (usually 5–10 years)

2. Estimating a terminal value

3. Applying a discount rate (WACC or risk-adjusted rate)

4. Adjusting for control premiums or synergies if needed

3. Fair-value hierarchy and key assumptions

Inputs used to measure fair value must be categorized by level:

Fair Value Level	Nature of Inputs	Example Inputs
Level 1	Quoted market prices	Stock price of identical company
Level 2	Observable inputs, indirect	Industry-specific multiples from transactions
Level 3	Unobservable inputs, entity-specific	Forecasted cash flows, internal assumptions

Key assumptions include:

• Long-term revenue growth rates

• Operating margins

• Capital expenditures and working capital requirements

• Terminal value assumptions

• Discount rate (including risk-free rate, beta, and equity risk premium)

Sensitivity analysis should be performed on these assumptions to assess how small changes affect the valuation outcome.

4. Impairment loss recognition

Condition	Action (US GAAP)	Action (IFRS)
Fair value ≥ carrying amount	No impairment	No impairment
Fair value < carrying amount	Impairment loss = excess of carrying over FV	Impairment allocated first to goodwill

US GAAP (ASC 350)The difference between the carrying amount and fair value is recorded as an impairment loss, limited to the balance of goodwill. No further allocation is required.

IFRS (IAS 36)The excess is allocated first to goodwill, and then pro rata to other assets in the CGU (excluding financial assets, deferred tax assets, and inventory), based on relative carrying amounts.

5. Example of quantitative impairment test

Scenario

Carrying amount of reporting unit (including goodwill): $120 millionEstimated fair value from DCF: $100 millionGoodwill on books: $40 million

US GAAP outcome: Impairment loss = $120M – $100M = $20MLoss recognized directly against goodwill → new goodwill balance = $20M

IFRS outcome: Same $20M lossAllocated first to goodwill → goodwill reduced from $40M to $20MAny remaining excess (if applicable) would reduce other CGU assets pro rata

6. Supporting documentation and controls

Entities must retain detailed support for:

• Forecasting models and assumptions

• Valuation methodologies and data sources

• Determination of discount rates

• Sensitivity analyses and scenario testing

• Auditor-reviewed memos validating reasonableness and consistency

Valuation specialists may be involved when internal resources lack experience with complex cash flow modeling or market-based techniques.

7. Interim and annual test integration

• Annual tests should use updated long-range plans, market conditions, and internal expectations.

• Interim tests must reflect the facts and circumstances of the triggering event and may rely on short-term data and scenario-based valuation.

• Comparability across years is essential; methodology and assumptions must be consistent unless clearly justified.

Key take-aways

• The quantitative goodwill impairment test requires careful estimation of fair value using DCF, market multiples, or both.

• Unrealistic assumptions or inconsistent valuation methods may trigger auditor pushback or regulatory review.

• US GAAP and IFRS differ in how the impairment is applied once it is identified—US GAAP limits loss to goodwill, while IFRS may affect other assets.

• Timely detection of impairment risk and robust valuation practices are central to accurate reporting and investor confidence.
