How to Perform a Quantitative Goodwill Impairment Test and Record a Goodwill Impairment Charge
Comparing the fair value of a reporting unit to its carrying value (including goodwill) and recording an impairment charge equal to the excess of carrying value over fair value, not to exceed the goodwill balance.
| Account Name | Type | Debit ($) | Credit ($) |
|---|---|---|---|
| Goodwill Impairment Charge (Non-Operating) | Expense (+) | 185,000,000.00 | - |
| Goodwill (Written Down) | Asset (-) | - | 185,000,000.00 |
💡 Accountant's Note
Post-ASU 2017-04 (one-step test): Impairment = Carrying value of reporting unit − Fair value of reporting unit. Capped at the goodwill balance (cannot reduce goodwill below zero). Fair value of a reporting unit is typically determined using a DCF analysis (income approach) and/or a market approach (comparable company multiples). The income approach: project free cash flows for 5-10 years, add a terminal value (Gordon Growth Model), discount at the WACC. Goodwill impairment is NOT reversible under US GAAP (once impaired, the write-down is permanent). Under IFRS (IAS 36): goodwill impairment is also non-reversible. The impairment charge is a non-cash P&L charge that reduces book equity and may trigger covenant violations in debt agreements.
Practitioner & Systems Framework
💻 ERP Architecture
Goodwill impairment charges must be allocated by reporting unit — the impairment reduces goodwill only for the specific reporting unit that failed the test. If a reporting unit has multiple acquisitions contributing to goodwill, all associated goodwill is tested together (but impaired proportionally per the test). The impairment is presented as a separate line item on the income statement (typically below operating income for segment reporting). Tax deductibility of goodwill impairment: goodwill amortization is deductible in asset deals (Section 197 — 15-year straight line) but impairment of non-deductible book goodwill creates a permanent difference (no deferred tax benefit).
⚠️ Audit Flags
Goodwill impairment is a top-10 SEC comment area. Auditors focus on the DCF assumptions: (1) revenue growth rates (must be supportable by industry data and historical performance), (2) EBITDA margins (must reflect realistic cost structure), (3) Terminal growth rate (cannot exceed long-run GDP growth for most businesses — 2-3%), (4) WACC (must use current market inputs — risk-free rate, equity risk premium, beta). If market capitalization is below book value for a single-reporting-unit company, impairment is almost certainly required unless there is a compelling reconciliation between market cap and fair value.
