ASC 350, the FASB standard on intangibles—goodwill and other, governs how a company carries acquired goodwill and other intangible assets on its books after the deal closes. It sorts those assets into three tracks. Goodwill is not amortized by public companies and is tested for impairment at least once a year. Intangibles with an indefinite useful life follow the same no-amortization, annual-test approach. Intangibles with a finite useful life are amortized over that life and tested for impairment only when something happens to suggest their carrying amount is no longer recoverable. Which track an asset falls on drives its effect on earnings for as long as it sits on the balance sheet.
How Goodwill Gets on the Balance Sheet
Goodwill only arises through an acquisition. Internally generated goodwill—the value of your own brand, workforce, or customer relationships built up over time—cannot be recorded, no matter how real that value feels. When one company buys another, the acquirer runs a purchase price allocation under ASC 805, assigning fair values to every identifiable asset acquired and liability assumed. Whatever purchase price remains after that allocation is goodwill.1Deloitte Accounting Research Tool. 5.1 Measuring Goodwill
Formally, goodwill is the sum of the consideration transferred, the fair value of any noncontrolling interest, and the fair value of any previously held equity interest in the target, minus the net fair value of the identifiable assets and liabilities. Pay $500 million for a target whose identifiable net assets are worth $400 million at fair value and you book $100 million of goodwill. That residual captures expected synergies, market position, assembled workforce, and other benefits that cannot be separated and measured on their own.
Before anything drops into that residual, the acquirer must identify and separately recognize every intangible asset that meets one of two tests: it arises from a contract or other legal right, or it can be separated from the business and sold, transferred, or licensed. Patents, customer lists, trade names, and licensing agreements typically clear one of these tests and get recorded at fair value apart from goodwill.2Deloitte Accounting Research Tool. 4.1 Overall Accounting for Intangible Assets
Fair values in the allocation are often provisional at closing. ASC 805 gives the acquirer a measurement period of up to one year to finalize amounts as new information about facts existing at the acquisition date comes to light.3FASB. ASC 805-10-25-14 Through 25-15 – Measurement Period One point that trips people up: acquisition-related costs such as legal fees, due diligence, valuation work, and finder’s fees are expensed as incurred. They do not roll into goodwill. Only costs tied to issuing debt or equity used to finance the deal can be capitalized.4Deloitte Accounting Research Tool. 7.8 Transactions That Are Separate From the Business Combination
If the acquirer somehow pays less than the net fair value of the identifiable assets and liabilities, ASC 805 does not permit negative goodwill on the balance sheet. The excess is recognized as an immediate gain on the income statement, but only after the acquirer reassesses every identified asset, assumed liability, and the consideration transferred to confirm the apparent bargain is real. That mandatory reassessment exists because most apparent bargain purchases turn out to be misidentified assets, understated liabilities, or stale fair value estimates.5Deloitte Accounting Research Tool. 5.2 Measuring a Bargain Purchase Gain
Finite Life vs. Indefinite Life for Other Intangibles
Every intangible asset other than goodwill gets classified as either finite-life or indefinite-life, and that call decides everything about how the asset is carried afterward.2Deloitte Accounting Research Tool. 4.1 Overall Accounting for Intangible Assets
Finite-Life Intangibles
A finite-life intangible is amortized over its useful life. The method should reflect the pattern in which the asset’s economic benefits are consumed; if that pattern cannot be reliably determined, use straight-line. The useful life estimate pulls in legal, regulatory, contractual, and economic factors, and it cannot exceed any contractual or legal life the asset carries. A patent with a 20-year legal life may have a useful life of only seven years if the underlying technology is turning over quickly. A customer list may amortize over five years based on expected attrition. Impairment for finite-life intangibles is tested under ASC 360, not ASC 350.
Indefinite-Life Intangibles
An intangible asset has an indefinite useful life when no foreseeable limit exists on how long it will generate cash flows. Certain trade names and broadcast licenses often fit here. These assets are not amortized, but they must be tested for impairment at least once a year, and more often if circumstances suggest a decline in value.6Deloitte Accounting Research Tool. 4.5 Reevaluating the Useful Life of an Intangible Asset Indefinite does not mean permanent. The classification is reassessed each reporting period, and if the useful life becomes finite, the asset switches to amortization going forward after a final ASC 350 impairment test.
Testing Goodwill for Impairment
Because goodwill is not amortized, impairment testing is the only mechanism keeping it honest on the balance sheet. The test happens at the reporting unit level—typically an operating segment or one level below it that qualifies as a business with discrete financial information.
The Optional Qualitative Assessment
Before running a quantitative test, a company can perform a qualitative assessment (sometimes called step zero) to decide whether a full test is even necessary. The question is whether it is more likely than not—more than a 50 percent chance—that the reporting unit’s fair value has fallen below its carrying amount. Factors considered include macroeconomic conditions, industry shifts, cost pressures, declining cash flows, management turnover, and sustained drops in share price.7Deloitte Accounting Research Tool. 2.3 Qualitative Assessment (Step 0) If management concludes fair value comfortably exceeds carrying amount, no further testing is needed that period. The qualitative screen can also be skipped entirely in any year, with the quantitative test run instead, and a company can return to the qualitative approach later.
The Quantitative Test
Under the simplified approach adopted through ASU 2017-04, the quantitative test is a single-step comparison. The fair value of the reporting unit—usually estimated through discounted cash flow analysis, comparable transaction multiples, or a mix—is compared to its carrying amount, including allocated goodwill. If fair value exceeds carrying amount, no impairment. If carrying amount exceeds fair value, the difference is booked as an impairment loss, capped at the goodwill allocated to that reporting unit.
Take a reporting unit with a $1.2 billion carrying amount and $1 billion fair value. The $200 million shortfall is the impairment charge, unless the unit only carries $150 million of goodwill, in which case the write-down stops at $150 million and goodwill goes to zero. The charge hits the income statement as an operating expense in the period recognized and permanently reduces goodwill on the balance sheet. Once written down, goodwill cannot be written back up in later periods, even if the reporting unit recovers.8Deloitte Accounting Research Tool. A.8 ASC 350, Intangibles – Goodwill and Other
Impairment Testing for Other Intangibles
The rules for non-goodwill intangibles diverge based on classification, and the two categories run on entirely different models.
Finite-Life Intangibles Under ASC 360
Finite-life intangibles are tested only when a triggering event occurs. There is no annual requirement. A triggering event is any change in circumstances suggesting the carrying amount may not be recoverable. Common examples:
- A significant drop in the asset’s market value.
- A major shift in how the asset is used, or significant physical deterioration.
- An adverse regulatory action, loss of a major customer, or general economic downturn affecting the asset.
- Acquisition or development costs significantly exceeding original expectations.
- A pattern of current and projected operating losses associated with the asset’s use.
- A current expectation that the asset will be sold or disposed of well before the end of its estimated useful life.
When a triggering event happens, the test runs in two steps. First, a recoverability test compares the carrying amount to the total undiscounted future cash flows expected from the asset’s use and eventual disposal. Pass that and no impairment is recognized. Fail it and the second step compares carrying amount to fair value, with any excess recognized as an impairment loss. The undiscounted cash flow screen is deliberately a lower bar than fair value, so that only assets with genuinely impaired economics reach the more rigorous measurement step.
Indefinite-Life Intangibles Under ASC 350
Indefinite-life intangibles are tested on the same annual cadence as goodwill. A company may start with a qualitative screen; if that raises concerns or is skipped, the quantitative test simply compares carrying amount to fair value, and any excess is booked as an impairment loss. As with goodwill, these write-downs are permanent.
Where the Book Rules Split From the Tax Rules
The tax treatment of goodwill and intangibles diverges sharply from ASC 350, and the gap has real reporting consequences. Under Internal Revenue Code Section 197, acquired goodwill and most other acquired intangibles amortize straight-line over 15 years, starting in the month of acquisition, regardless of the asset’s actual economic life.10Office of the Law Revision Counsel. 26 U.S. Code 197 – Amortization of Goodwill and Certain Other Intangibles Section 197 sweeps in going concern value, workforce in place, customer-based and supplier-based intangibles, patents, copyrights, know-how, non-compete covenants, government-granted licenses, franchises, trademarks, and trade names. The 15-year deduction continues even if the asset is impaired for book purposes.
Section 197 applies to taxable asset acquisitions and to stock acquisitions where a Section 338(h)(10) or Section 336(e) election converts the deal into an asset purchase for tax. In a straight stock acquisition without such an election, the buyer generally gets no basis step-up and therefore no Section 197 deduction.
For a public company, then, goodwill sits flat on the books (absent impairment) while its tax basis shrinks each year. That growing temporary difference generates a deferred tax liability under ASC 740. At a 21 percent corporate rate on $1 billion of tax-deductible goodwill, the DTL grows by roughly $14 million a year.11Deloitte Accounting Research Tool. 11.3 Recognition and Measurement of Temporary Differences When a book impairment happens, the interaction between the write-down and continuing tax amortization can require an iterative simultaneous-equations calculation to arrive at the final impairment charge.
The Private Company and Not-for-Profit Alternatives
Annual goodwill impairment testing is expensive, and for many private companies the cost outweighs the benefit. The Private Company Council introduced alternatives that materially simplify the accounting.
A private company can elect to amortize goodwill straight-line over 10 years, or a shorter period if the company can demonstrate one is more appropriate. The 10-year default requires no justification. Different acquisitions can carry different periods, none exceeding 10 years.12Deloitte Accounting Research Tool. 3.3 Goodwill Amortization Alternative Electing entities test for impairment only when a triggering event occurs, not annually, and may run the test at the entity level rather than by reporting unit. ASU 2019-06 extended the same amortization and simplified testing alternatives to not-for-profit entities.13FASB. ASU 2019-06 – Intangibles, Goodwill and Other (Topic 350)
A further alternative under ASU 2021-03 lets private companies and not-for-profits evaluate triggering events only as of the end of each reporting period, rather than monitoring continuously. If a triggering event is identified at the reporting date, the impairment test still runs.14Deloitte Accounting Research Tool. FASB Provides Private Companies and Not-for-Profit Entities With Goodwill Impairment Triggering Event Alternative One caution before electing any of these alternatives: a private company that later becomes a public business entity must reverse the effect of the private-company accounting in its historical financial statements, which can be costly to unwind at the wrong time.
Disclosure Requirements
ASC 350 requires disclosures designed to show investors the composition and valuation of intangible assets. For goodwill, that means the carrying amount in total and for each reporting unit, the method and key assumptions used to determine fair value during impairment testing, and whether the qualitative assessment or the quantitative test was used.
When a goodwill impairment loss is recognized, disclosures must include the facts and circumstances leading to it, the amount, the method used to determine the reporting unit’s fair value, and the income statement line item where the loss appears.8Deloitte Accounting Research Tool. A.8 ASC 350, Intangibles – Goodwill and Other
For other intangibles, disclose the carrying amount and weighted-average amortization period for each major class of finite-life intangibles, and the estimated aggregate amortization expense for each of the next five fiscal years. Impairment losses require disclosure of the impaired asset, the circumstances, the loss amount, the fair value measurement method, and the applicable operating segment.
What Could Change: FASB’s Ongoing Review
The impairment-only model for public company goodwill has drawn persistent criticism over cost and subjectivity. FASB has been deliberating whether to reintroduce amortization for public companies, and in late 2020 tentatively decided to require straight-line amortization over a 10-year default period. As of 2025, that project has not resulted in a final Accounting Standards Update, and public companies remain under the impairment-only model. Any change would meaningfully alter how acquired goodwill flows through earnings, and preparers tracking this topic should watch FASB’s project page for developments.
