The test that turns a valuation into a financial statement conclusion: reporting units, triggers, the quantitative mechanics, and the disclosure the SEC expects before the charge ever lands.
We run the test as company-side preparers: the units, the triggers, the valuation inputs, and the memo, defended before the charge, not after.
What it is. Goodwill is tested for impairment at the reporting unit, at least annually and on triggering events, through an optional qualitative screen and a single-step quantitative comparison of carrying amount to fair value.
Where it breaks. Reporting-unit definition, triggering events spotted late, valuations that do not reconcile to market capitalization, and step-zero conclusions documented too thinly to stand.
How we help. We map the units, run or review the valuation, document the conclusion, and keep the file ready for the auditors and the disclosure that follows a miss.
Goodwill sits on the balance sheet as the accumulated premium paid in every acquisition, and ASC 350 asks one recurring question about it: does the business you bought still support the number you carry? The test itself is now a single step, but everything around it is judgment, where the reporting units sit, when a trigger fires, what the forecast assumes, and how the answer reconciles to a market that may already disagree with your books.
We run impairment testing as company-side preparers: the reporting unit architecture, the trigger monitoring, the valuation coordination, and the memo the auditors test. Where the goodwill came from, the allocation mechanics that created it, lives on our ASC 805 page; here is the discipline of carrying it afterward.
The standard
The test, from trigger to conclusion
Goodwill is not amortized under the general model, so it lives on the balance sheet until a test says otherwise. The test runs at the reporting unit: at least annually, at the same time each year, and whenever a triggering event lands. The optional qualitative screen stops the work when fair value is comfortably above carrying amount; otherwise the quantitative test compares the two directly. If other assets are also impaired, they are tested and adjusted first; goodwill goes last. We run the sequence, document the step-zero conclusion or build the valuation, and keep the file audit-ready.

The measurement
How a goodwill impairment charge is measured
The measurement is one comparison: the reporting unit's carrying amount against its fair value, with the excess recognized as impairment up to the goodwill on the unit's books. Fair value comes from income and market approaches, weighted, and for public companies reconciled to market capitalization. Tax-deductible goodwill adds a deferred tax effect measured through a simultaneous equation. Cushion in one unit cannot offset a shortfall in another, which is why how the units are defined so often decides the answer.
A single reporting unit shown; the loss is the excess of carrying amount over fair value, capped at goodwill.

Our Experience
Where we have done this work
Engagement Notes
Cyclical businesses, tested through the cycle
Standing impairment programs for capital-intensive and cyclical companies, semiconductor equipment economics among them: reporting unit architecture documented ahead of the downturn, quarterly trigger memos that answered the interim question before auditors asked it, and DCFs built on forecasts that owned the trajectory rather than assuming it away.
Engagement Notes
Acquisitive platforms, from allocation to annual test
Goodwill lifecycles run end to end for sponsor-backed and strategic acquirers: goodwill assigned to reporting units at each close, reallocations on relative fair value through reorganizations, private-company alternative elections decided against the exit path, and at-risk disclosure drafted alongside the tests that motivated it.
The Detail
The gaps, and how we close each one
Issue 01
Reporting units: the architecture that decides the answerASC 350-20
Impairment is tested at the reporting unit, so the unit structure quietly determines the outcome: broad units let strong businesses shelter weak ones, narrow units expose every soft spot, and reorganizations move goodwill between them under rules teams rarely apply.
The treatment
A reporting unit is an operating segment or one level below, a component, where the component is a business with discrete financial information that segment management regularly reviews; components with similar economic characteristics aggregate. The architecture work happens at acquisition: assign the acquired assets, liabilities, and goodwill to units based on which units benefit from the deal’s synergies, beyond where the target sits organizationally. When the business reorganizes, goodwill reallocates between affected units on a relative fair value basis, a valuation exercise teams skip and auditors catch, and a disposal carves goodwill out of the unit the same way. Document the unit structure, refresh it when segments or management reporting change (an ASC 280 conclusion change usually drags this one with it), and resist the temptation to redraw units in a soft year, because the redrawing is itself scrutinized as results-driven.
What we do: We document the reporting unit architecture, assign goodwill at each acquisition, and run the relative fair value reallocations when the business reorganizes.
Issue 02
When to test: the annual date, the triggers, and the qualitative optionTriggers & Step Zero
The annual test has a chosen date; the triggering events do not. Macro deterioration, lost customers, margin compression, and a market cap sliding below book value all demand interim assessment, and companies that only think about goodwill in Q4 discover triggers with three quarters of hindsight.
The treatment
Elect an annual test date and hold it consistently (many choose an early-Q4 date to keep the work off the year-end close), then run a standing quarterly trigger review: macroeconomic and industry conditions, cost inflation against pricing power, actual results versus the forecast the last test relied on, unit-level events (customer losses, leadership exits, strategy shifts), and, for public companies, sustained market capitalization below book value, the trigger the SEC staff asks about by name. The qualitative assessment (step zero) lets you skip the quantitative test when it is more likely than not that fair value exceeds carrying amount; it earns its keep for units with wide, documented headroom from a recent quantitative test, and wastes everyone’s time for units anywhere near the line, where a qualitative memo long enough to be defensible costs more than the DCF it avoids. We run the trigger review as a one-page quarterly memo, so the interim question is always answered before anyone else asks it.
What we do: We run the quarterly trigger review as a one-page standing memo and choose step zero versus quantitative per unit, per year.

The quantitative test: one step, several battlegroundsThe Test
Since ASU 2017-04 eliminated the hypothetical purchase price allocation, the test is simple to state, fair value of the reporting unit versus its carrying amount, and every input is a battleground: the forecast, the discount rate, the terminal assumptions, and the multiples chosen as corroboration.
The treatment
Measure the reporting unit’s fair value, ordinarily weighting an income approach (a DCF on unit-level cash flows) against a market approach (guideline company multiples), and recognize impairment for any excess of carrying amount over fair value, capped at the goodwill balance. The defensibility lives in the inputs: a forecast that reconciles to the board-approved plan and to the unit’s actual trajectory (hockey sticks after two missed years are the classic finding), a discount rate built from the unit’s risk rather than the parent’s WACC by default, terminal growth that does not outrun the economy, and market multiples drawn from genuinely comparable companies. Deductible goodwill adds the simultaneous-equation mechanics, where the charge changes the deferred taxes that change the carrying amount, a computation to run, not approximate. We coordinate the valuation specialists, challenge the inputs before the auditors do, and write the memo that connects model to conclusion.
What we do: We coordinate the valuation, challenge the forecast and rate inputs before the auditors do, and write the memo connecting model to conclusion.
From our engagements: The forecast is where impairment tests are won and lost. A DCF that assumes away two years of underperformance fails review every time; a forecast that owns the trajectory and still clears carrying value is a position we can defend.

The ordering rule: what gets tested before goodwillSequence
Goodwill is tested last, and companies routinely run it first: indefinite-lived intangibles and long-lived asset groups must be tested and any impairment booked before the goodwill test, because their write-downs change the carrying amount goodwill is measured against.
The treatment
Run the sequence: indefinite-lived intangibles first (trade names under relief-from-royalty, with the indefinite-life conclusion itself reassessed each period, a brand being phased down should move to finite life before anyone debates its value), then long-lived assets and finite intangibles at the asset-group level under ASC 360’s undiscounted recoverability test, then goodwill at the reporting unit. The two levels differ on purpose: asset groups are the lowest level of independent cash flows, usually narrower than reporting units, so a plant can fail its ASC 360 test inside a reporting unit that passes its ASC 350 test, and both conclusions can be right. Booking the sequence out of order overstates or understates the goodwill charge and is a mechanical error auditors are trained to find. Our impairment memos run all three layers in one document, in order, so the interaction is visible rather than accidental.
What we do: We run all three impairment layers in one document, in the required order, so the interactions are visible rather than accidental.

Market cap reconciliation and the disclosure before the chargeDisclosure
For public companies the test has an audience: a market cap below book value is a standing question, reviewers expect early-warning disclosure for at-risk reporting units, and the charge itself, when it comes, is judged partly on whether the prior filings saw it coming.
The treatment
Reconcile the sum of reporting unit fair values to market capitalization plus a supportable control premium; a persistent gap the premium cannot honestly bridge is both an audit issue and a comment letter waiting. Before any charge, MD&A critical estimates should carry the at-risk disclosure the staff expects: which reporting units have limited headroom, the percentage by which fair value exceeded carrying amount at the last test, the key assumptions and their sensitivity, and the events that could tip the conclusion, disclosure that reads as foresight when the charge lands and as an omission when it is missing. When impairment is recognized, the 8-K question (Item 2.06 where the conclusion crystallizes a material charge), the footnote mechanics, and the non-GAAP treatment of the charge in the earnings release all follow. We draft the early-warning disclosure alongside the test itself, because the filing that predicted the charge is the one that survives it.
What we do: We reconcile unit values to market cap and draft the at-risk disclosure alongside the test that motivated it.
Issue 06
The private company alternatives, and life after a chargePrivate Company GAAP
Private companies can opt out of most of this, amortizing goodwill and testing only on triggers, and the elections are genuinely simpler and genuinely costly to unwind. And for everyone, an impairment charge has an afterlife: covenants, taxes, and the permanent one-way nature of the write-down.
The treatment
Private companies may elect to amortize goodwill over ten years or less and to test only upon a triggering event, with the further accommodation of evaluating triggers as of the reporting date rather than continuously, elections that eliminate the annual test entirely and suit companies with no exit ambitions, but that get rebuilt at real cost in an IPO or sale to a public acquirer, which is why we decide them with the exit path on the table (the same conversation as on our ASC 805 page). For every company, the aftermath of a charge is mechanical and permanent: no reversal ever, even when the business recovers; covenant packages read the charge through their definitions (many EBITDA-based covenants add it back, balance-sheet covenants may not); deferred taxes move where goodwill was deductible; and the next year’s test starts from the written-down base, which paradoxically makes second impairments harder to trigger and first disclosures more important. The write-down is permanent, which is the best argument for testing carefully now rather than being forced into a charge later.
What we do: We decide the private-company elections against your exit path and manage the aftermath of any charge through covenants, taxes, and the next test.
FAQ
Frequently asked questions
Our market cap dropped below book value. Do we have to take a charge?
Not automatically, but you have a trigger and a question to answer. A sustained shortfall demands an interim assessment, a reconciliation of unit fair values to market cap with a supportable control premium, and usually at-risk disclosure. The charge follows only if the test fails; the assessment is not optional.
Can we use the qualitative assessment to skip the valuation?
When headroom is wide and documented from a recent quantitative test, yes, that is what step zero is for. Near the line, a defensible qualitative memo costs more than the DCF it avoids, and auditors discount thin ones. We choose per unit, per year.
Who builds the valuation, you or a valuation firm?
Both, in defined roles: valuation specialists run the models where independence or complexity warrants it, and we own the company-side inputs, the forecast reconciliation, the reporting unit architecture, the memo, and the defense through audit. The failure mode is a model nobody connected to the books; our job is the connection.
Does an impairment charge ever reverse if the business recovers?
Never, under US GAAP. Recovery shows up as future earnings on a lower asset base, not as a write-up. That permanence is why the ordering rules, the forecast discipline, and the disclosure before the charge all matter as much as the test itself.
We elected the private company goodwill alternatives. What happens if we IPO?
The elections unwind: public-company GAAP requires recapitalizing the accounting as if the alternatives had not been applied, a real project across every acquisition since election. It is manageable with runway and painful discovered late, which is why the election belongs in the exit conversation.
