SECTION 1
Historical Context & Motivation
For decades, the balance sheet carried long-lived assets at historical cost less accumulated depreciation, with little mechanism for recognizing that an asset's economic value might have permanently declined. The accounting profession had no formal, uniform standard requiring companies to test whether their property, plant, and equipment—or intangible assets—still justified the amounts reported on the books. The absence of such guidance meant that investors could be misled by inflated asset values, particularly after economic downturns or technological disruption rendered certain assets economically obsolete. Regulatory bodies recognized that a faithful representation of financial position demanded rules governing both the disposal and the impairment of assets whose carrying amounts could no longer be recovered through future cash flows or fair value.
1970 • APB Opinion No. 30
1995 • SFAS No. 121 – Impairment of Long-Lived Assets
2001 • SFAS No. 144 – Accounting for the Impairment or Disposal of Long-Lived Assets
2009 • ASC Codification – ASC 360-10
2017 • ASU 2017-04 – Simplifying Goodwill Impairment
Against this backdrop, today's CPA candidates must answer a central question: when and how should the carrying amount of a long-lived asset be reduced, and what journal entries capture a disposal or impairment event? The following sections build the complete framework you need for both the FAR exam and professional practice.
SECTION 2
Core Principles & Definitions
The treatment of asset disposals and impairment rests on several interconnected principles drawn primarily from ASC 360-10 (Property, Plant, and Equipment) and ASC 350 (Intangibles—Goodwill and Other). Understanding these foundational ideas will anchor every journal entry and disclosure requirement you encounter on the CPA exam.

Visual Explanation — Impairment Decision Flowchart
The diagram emphasizes that the impairment framework for assets held for use is a two-step process. Step 1 uses undiscounted cash flows as a screening mechanism—a deliberately generous threshold that only flags the most clearly impaired assets. If the asset fails this initial screen, Step 2 measures the loss by comparing the carrying amount to the asset's fair value, which is typically determined using a discounted cash flow model, comparable market transactions, or an independent appraisal. Once recorded, the reduced carrying amount becomes the new depreciable basis and is depreciated over the asset's remaining useful life. Unlike IFRS (IAS 36), U.S. GAAP does not permit reversal of impairment losses on long-lived assets other than certain financial assets.
SECTION 4
Mathematical Framework
Impairment Loss — Assets Held for Use
RECOVERABILITY TEST
Carrying Amount = Cost − Accumulated Depreciation − Prior Impairments. Undiscounted future cash flows include all cash inflows expected from the asset's use and eventual disposal, without applying a discount rate.
IMPAIRMENT LOSS MEASUREMENT
Fair Value is determined under ASC 820 using Level 1 (quoted prices), Level 2 (observable inputs), or Level 3 (unobservable inputs) of the fair value hierarchy. The new carrying amount equals the original carrying amount minus the impairment loss.
Assets Held for Sale
HELD-FOR-SALE MEASUREMENT
Costs to sell include broker commissions, legal fees, and other incremental direct costs. Depreciation stops upon classification as held for sale. Subsequent increases in fair value (net of costs to sell) may reverse previously recognized held-for-sale write-downs, but only up to the cumulative loss previously recorded.
Gain or Loss on Disposal
DISPOSAL GAIN / LOSS
Net Proceeds = Selling Price − Selling Costs. If the asset is abandoned or retired without sale, Net Proceeds = $0 and the entire remaining carrying amount is recognized as a loss. Gains and losses on disposal are typically reported in operating income unless they qualify as discontinued operations under ASC 205-20.

Detailed Breakdown — Disposal Methods & Held-for-Sale Criteria
When a company decides to part with a long-lived asset, the accounting treatment depends on the method of disposal and whether specific criteria for held-for-sale classification are met. ASC 360-10-45-9 enumerates six conditions, all of which must be satisfied at the balance sheet date for reclassification. If any criterion is not met, the asset remains classified as held and used, continues to be depreciated, and follows the standard impairment model discussed in Section 3.
When an asset is reclassified as held for sale, it is presented separately on the balance sheet—typically as a line item in current assets if the sale is expected within one year. The entity writes the asset down to fair value less costs to sell at the reclassification date if that amount is lower than carrying amount, recording the write-down as a loss on the income statement. Subsequent recoveries of that write-down are permitted, but only to the extent of cumulative losses previously recognized under the held-for-sale framework. This recovery provision is a notable exception to the general U.S. GAAP prohibition on reversing impairment losses for long-lived assets held for use.
SECTION 6
Worked Example — Impairment & Subsequent Disposal
Apex Manufacturing owns a specialized stamping machine that it purchased five years ago for $500,000. The machine has been depreciated on a straight-line basis over a 10-year useful life with no salvage value, so accumulated depreciation is $250,000 and the carrying amount is $250,000. Due to a shift in consumer demand, management determines that the machine's expected undiscounted future cash flows over its remaining life total $200,000, and its fair value is $160,000. Two years later, Apex sells the machine for $130,000 net of selling costs.
Impairment Test & Disposal of Stamping Machine
- 1
Step 1 — Identify the Triggering Event
A significant shift in consumer demand has reduced the expected future cash flows from the stamping machine. Under ASC 360-10-35-21, a change in the business climate that affects the asset's future use constitutes a triggering event requiring an impairment analysis. - 2
Step 2 — Apply the Recoverability Test
Compare the carrying amount of $250,000 to the sum of undiscounted future cash flows of $200,000. Because $250,000 > $200,000, the asset fails the recoverability test, and an impairment loss must be measured.Recoverability test failed: $250,000 > $200,000 - 3
Step 3 — Measure the Impairment Loss
Impairment Loss = Carrying Amount − Fair Value = $250,000 − $160,000 = $90,000. Note that we use fair value (not undiscounted cash flows) for the measurement step.Impairment Loss = $90,000 - 4
Step 4 — Record the Impairment Journal Entry
Dr. Impairment Loss on Long-Lived Assets … $90,000 Cr. Accumulated Depreciation — Machine … $90,000 After the entry, the net carrying amount is $500,000 − $250,000 − $90,000 = $160,000. This becomes the new depreciable base, depreciated over the remaining 5-year useful life at $32,000 per year.New carrying amount = $160,000; New annual depreciation = $32,000 - 5
Step 5 — Depreciate Over Remaining Life (2 Years)
Over the next two years before sale, the machine is depreciated at $32,000 per year × 2 = $64,000. The carrying amount at date of sale = $160,000 − $64,000 = $96,000.Carrying amount at disposal date = $96,000 - 6
Step 6 — Record the Disposal
Net proceeds from the sale = $130,000. Gain on disposal = $130,000 − $96,000 = $34,000. Dr. Cash … $130,000 Dr. Accumulated Depreciation — Machine … $404,000 Cr. Machine (Cost) … $500,000 Cr. Gain on Disposal of Equipment … $34,000 Accumulated depreciation at disposal = $250,000 (original) + $90,000 (impairment) + $64,000 (post-impairment depreciation) = $404,000.Gain on Disposal = $34,000
SECTION 7
Comparing Impairment Models — U.S. GAAP vs. IFRS
While the CPA FAR exam focuses on U.S. GAAP, understanding the differences with IFRS (specifically IAS 36 — Impairment of Assets) is increasingly relevant given international convergence efforts and the global nature of modern financial reporting. The table below highlights the most significant divergences between the two frameworks.
| Feature | U.S. GAAP (ASC 360) | IFRS (IAS 36) |
|---|---|---|
| Impairment indicator | Test only when triggering events or circumstances suggest carrying amount may not be recoverable. | Assess at each reporting date whether any indication of impairment exists; goodwill and indefinite-life intangibles tested annually regardless. |
| Screening step | Recoverability test using undiscounted future cash flows (Step 1). | No separate screening step; proceed directly to comparing carrying amount with recoverable amount. |
| Measurement basis | Fair value (ASC 820). | Recoverable amount = higher of fair value less costs of disposal and value in use (discounted cash flows). |
| Reversal of impairment | Prohibited for assets held for use. Limited reversal for held-for-sale write-downs. | Permitted (except for goodwill). Reversal limited to original carrying amount adjusted for depreciation. |
| Asset grouping | Lowest level at which identifiable cash flows are largely independent of other asset groups. | Cash-generating unit (CGU) — smallest identifiable group of assets generating independent cash inflows. |

Connections to Goodwill Impairment & Discontinued Operations
The asset disposal and impairment framework under ASC 360 operates alongside two closely related areas that frequently appear on the CPA exam: goodwill impairment (ASC 350-20) and discontinued operations (ASC 205-20). Understanding how these topics intersect with long-lived asset impairment is essential for a holistic view of financial statement effects.
| Dimension | Long-Lived Asset Impairment (ASC 360) | Goodwill Impairment (ASC 350-20) |
|---|---|---|
| Unit of account | Individual asset or asset group (lowest level with identifiable cash flows). | Reporting unit (operating segment or one level below). |
| Testing trigger | Events or changes in circumstances indicating non-recoverability. | Annual test required; interim test if triggering events occur. |
| Measurement | Two-step: undiscounted CF screen → fair value loss. | Single-step (post-ASU 2017-04): carrying amount of reporting unit (including goodwill) vs. fair value of reporting unit. Loss = excess, capped at goodwill balance. |
| Reversal | Not permitted (held for use). Partial reversal for held for sale. | Not permitted. |
| Ordering | Test long-lived asset groups first, then test goodwill at reporting-unit level. | Performed after other asset impairment tests within the same reporting unit. |
ASC 360 vs. ASC 350-20 impairment comparison
When an asset disposal qualifies as a discontinued operation under ASC 205-20, the results of operations and any gain or loss on disposal are reported separately in the income statement, net of tax, below income from continuing operations. The threshold for discontinued-operation classification was raised by ASU 2014-08, which now requires the disposal to represent a strategic shift with a major effect on operations and financial results (e.g., a major geographic area, line of business, or equity-method investee). This higher threshold means fewer disposals qualify as discontinued operations; most asset disposals instead flow through operating or other income on a gross basis.

SUMMARY
Lesson Summary
Summary
Asset disposals and impairment center on the principle that financial statements must faithfully represent the economic value of long-lived assets. Under ASC 360-10, assets held for use are subject to a two-step impairment test: the recoverability test compares carrying amount to undiscounted future cash flows (a lenient screen), and if it fails, the impairment loss is measured as carrying amount minus fair value. This loss is irreversible under U.S. GAAP, and the reduced carrying amount becomes the new depreciable basis.
For assets held for sale, six criteria must be met for reclassification, after which the asset is reported at the lower of carrying amount or fair value less costs to sell, with depreciation suspended and limited write-down recoveries permitted. Upon actual disposal, the gain or loss equals net proceeds minus carrying amount. Remember that goodwill impairment under ASC 350-20 uses a simplified single-step model, and long-lived assets must always be tested before goodwill within the same reporting unit to preserve measurement accuracy.
