A tenant company decides a floor it leases is surplus. The people move out, the space goes dark, and the natural assumption in the finance function is that the lease, or at least the cost of the empty space, comes off the books in some clean way. It does not. Under ASC 842, a leased property sits on the balance sheet as a right-of-use asset and a matching lease liability, and vacating the space does not, by itself, remove either one. What actually happens to the accounting depends on a set of distinctions the standard draws sharply and most operators draw loosely: whether the space is impaired, abandoned, subleased, or merely idle.

Those are four different situations with four different accounting outcomes, and the difference between them is measured in real charges to earnings. This article covers what stays on the books when you exit space, why impairment and abandonment are not the same event, and where the distinctions catch finance teams out. One note first: this is a summary of US GAAP treatment, not accounting advice, the guidance involves significant judgment, and the treatment of any specific lease is a question for your auditors and technical accounting team.

Why the Liability Does Not Move

Start with the point that surprises people most, because it frames everything else. When a company vacates leased space, its obligation to pay rent does not change. The lease liability on the balance sheet is the present value of the remaining contractual payments, and walking out of the space does not alter the contract. Unless the lease is legally terminated, modified, or bought out, the liability stays, and the cash keeps going out the door on the original schedule. RSM's technical guidance states the point plainly: the accounting for a lease liability changes only when a remeasurement is otherwise required or the lease is terminated. Abandoning the space is neither.

That is the first thing a CFO has to internalise: the decision to stop using space and the obligation to pay for it are independent. Vacating changes the economics of the space to zero on the benefit side while leaving the cost side fully intact. Everything the accounting does from here is about the other half of the entry, the right-of-use asset, because that is the part that can move when the space stops delivering value.

Once the liability is understood as fixed, the accounting question narrows to what happens to the right-of-use asset, and that depends entirely on what the company intends to do with the space.

Four Situations, Four Outcomes

The standard distinguishes several things that look similar from an operator's chair and are treated very differently in the accounts. Getting the wrong one misstates the balance sheet.

Merely idle.
If the space is temporarily unoccupied but the company intends to return to it, nothing special happens. Per PwC's guidance on ASC 360, temporarily idling a right-of-use asset, for example leaving leased space unoccupied with plans to return to it at a future date, is not considered an abandonment. The asset stays, and it continues under the normal held-and-used model. An empty floor is not, on its own, an accounting event.

Subleased, or intended to be.
Deciding to sublease is not abandonment either. The guidance is explicit that a decision to sublease does not constitute abandonment, because the lessee still intends to obtain economic benefit from the asset, just in a different capacity. And crucially, even uncertainty counts in this direction: provided the lessee has the intent and ability to sublease, the asset stays under the held-and-used model even if no sublessee has been identified yet. It is only when neither the intent nor the ability to sublease exists that the abandonment model applies.

Impaired.
This is the most common real outcome when space loses value but is not fully given up. A decision to vacate or downsize is an impairment indicator, which triggers a test of the asset group the space belongs to. If the asset group fails that test, the ROU asset is written down. Impairment reduces the asset; it does not remove it.

Abandoned.
This is the narrow case, and the bar is high. Abandonment applies only when the space is fully vacated with no intention to derive any further benefit, not even storage, and no realistic path to subleasing. The guidance notes that with a significant remaining lease term, abandonment is hard to support, because a reasonable party would likely try to benefit from the space somehow; it becomes supportable mainly when the remaining term is short and there is no reasonable possibility of subleasing.

The practical error to avoid is collapsing these four into one. "We left the floor" could mean any of them, and only two, impairment and abandonment, produce a charge. Calling a sublease situation an abandonment, or treating an idle floor as an impairment, puts the wrong number on the balance sheet.

How Impairment Actually Works

Because impairment is the outcome most finance teams will actually encounter, it is worth being precise about the mechanics, which are more involved than "write it down to what it's worth."

Under ASC 360, impairment is a two-step test, and the first step is not about fair value at all. As RSM's technical brief sets out, step one is a recoverability test that compares the carrying amount of the asset group to its undiscounted future cash flows; if the carrying amount is less than those undiscounted cash flows, the recoverability test is passed and no impairment is recognised. Only if the asset group fails that test do you move to step two and measure the loss by comparing carrying amount to fair value, determined under ASC 820.

Two features of this trip people up. First, the test is performed at the asset-group level, the lowest level at which cash flows are largely independent, not on the lease in isolation. RSM notes that an ROU asset typically does not have identifiable cash flows independent of other assets, so it is generally not tested standalone; a single vacated floor may sit inside a larger asset group whose combined cash flows are still recoverable, in which case no impairment is recognised despite the empty space. The unit of account is the group, not the lease. Second, the recoverability step uses undiscounted cash flows, which differs from the fair value used in step two; the two figures are deliberately different, since undiscounted cash flows ignore the time value of money and use an entity-specific view, while fair value uses a market-participant view. Applying a fair-value writedown without first running the undiscounted recoverability test is a common way to get impairment wrong.

There is also a consequence that outlasts the charge itself. Once an operating-lease ROU asset is impaired, its subsequent accounting changes, and it is worth being precise about how. The written-down balance is amortised straight-line over the shorter of the remaining lease term or useful life, but that amortisation is then combined with the accretion of the lease liability into a single lease cost, reported as one amount. The effect is that the level, straight-line rent expense an operating lease normally produces is gone; the periodic cost now moves with the liability's accretion, resembling a finance lease's expense pattern even though the ROU amortisation itself is straight-line. And under US GAAP the impairment is permanent: it cannot be reversed even if conditions later improve, a notable divergence from IFRS, where reversal is permitted under defined conditions.

Why This Reaches the CFO, Not Just the Controller

It would be easy to file this as technical accounting mechanics, but the reasons it belongs on a CFO's desk are specific.

The first is earnings timing. Impairment and abandonment charges are lumpy and land in a single period. A portfolio rationalisation that makes clean economic sense, giving up space the business no longer needs, can produce a concentrated hit to earnings in the quarter the decision is made, well before any cash is saved, and often while the cash cost of the lease continues unchanged. The economics and the accounting are on different clocks, and the CFO is the one who has to explain the gap between a sensible operational decision and an ugly-looking income statement.

The second is that the distinctions are decision-sensitive, which means they interact with strategy. Whether a vacated space is subleased or abandoned is partly a business choice, and that choice drives the accounting. A decision to market the space for sublease keeps it under the held-and-used model; a decision to give up on it entirely can support abandonment and accelerate the charge. Neither is automatically right, but a CFO should know that the exit strategy for surplus space and its accounting treatment are linked, and that the treatment is not a mechanical afterthought but a consequence of a decision the finance function influences.

The third is that all of this depends on knowing what you hold. The impairment test needs asset groups, remaining lease terms, carrying values, and cash-flow forecasts at the property level. The abandonment analysis needs the vacancy status and the realistic sublease prospects of each space. These are property-level facts, and a company exiting space across a portfolio has to assemble them per asset, on a timeline set by quarterly reporting rather than by convenience. A system that holds lease terms, carrying values, and property status together, RIOO among them, is where that assessment can be run as the events happen rather than reconstructed under audit pressure at period end. The accounting cannot be done at all without the underlying property data, which is the operator's to keep.

Conclusion

The intuition that leaving a space takes it off the books is one of the more expensive misconceptions in lease accounting, because it is wrong in a way that surfaces at quarter-end rather than at the moment of the decision. Under ASC 842 the lease liability stays until the contract itself changes, and the right-of-use asset moves only through specific events, impairment or abandonment, each with a high bar and a precise mechanic. Idling space does nothing. Subleasing, or even the intent and ability to sublease, keeps the asset in the held-and-used world. Only genuine loss of value, tested at the asset-group level, or genuine abandonment, fully vacated with no path to benefit, produces a charge, and once taken, an impairment reshapes the expense pattern for the rest of the term and cannot be undone.

For a CFO managing space in a market where surplus property is common, the discipline is to treat the exit decision and its accounting as a single question asked early, not two questions answered separately and late. The cost of the space does not leave when the people do. What leaves, and when, and how it hits earnings, is governed by distinctions worth getting right before the quarter closes, not after.

FAQs

1. Does vacating leased space remove it from the balance sheet?
No. Under ASC 842 the lease liability represents the remaining contractual payments and stays on the balance sheet until the lease is legally terminated, modified, or bought out. Vacating the space affects only the right-of-use asset, and only if the situation meets the definition of impairment or abandonment. Simply moving out does not remove either the asset or the liability.

2. What is the difference between lease impairment and lease abandonment?
Impairment is a writedown of the right-of-use asset when its asset group fails a recoverability test, while the asset generally remains in use or available for economic benefit. Abandonment applies only when the space is fully vacated with no intention of any further benefit, including storage, and no realistic prospect of subleasing. Impairment reduces the asset; abandonment applies in the narrower case of complete cessation of benefit, and is difficult to support when significant lease term remains.

3. Is subleasing space considered abandonment under ASC 842?
No. A decision to sublease is not abandonment, because the lessee still intends to obtain economic benefit from the asset. Provided the lessee has the intent and ability to sublease, the asset stays under the held-and-used model even before a sublessee is identified. Only when neither the intent nor the ability to sublease exists does the abandonment model apply.

4. How is an ROU asset impairment calculated?
Under ASC 360, it is a two-step test. First, the undiscounted future cash flows of the asset group are compared to its carrying value; if they equal or exceed carrying value, there is no impairment. Only if the asset group fails that recoverability test is the loss measured, as the amount by which carrying value exceeds fair value, determined under ASC 820. The test is performed at the asset-group level, not on the individual lease in isolation.

5. Can an impairment of a right-of-use asset be reversed?
Not under US GAAP. Once an ROU asset impairment is recognised under ASC 842 applying ASC 360, it is permanent and cannot be reversed even if conditions later improve. This differs from IFRS, where IAS 36 permits reversal of a previously recognised impairment under defined conditions, up to the carrying amount that would have existed had no impairment been taken.
