Executive summary

An IFRS 16 lease modification is one of the few events in the standard that can put a number straight into profit or loss without any cash moving. Everything turns on two questions asked in order: is this a modification at all, and if it is, does it decrease the scope of the lease. Get the first one wrong and the discount rate is wrong. Get the second one wrong and the gain is in the wrong place, or missing.

Background

Before IFRS 16, a lessee renegotiating an operating lease had very little to do. The lease was off balance sheet, the rent went through profit or loss on a straight-line basis, and a change in the rent changed the straight-line charge. There was no asset to remeasure and no liability to unwind. IAS 17 said almost nothing about modifications, and practice varied widely because nothing forced it not to.

IFRS 16 removed that space. It applies for annual periods beginning on or after 1 January 2019 and puts almost every lease on the lessee's balance sheet. Once a right-of-use asset and a lease liability exist, any change to the contract has to be pushed through both of them, and IFRS 16.44 to 16.46 sets out how. The result is that a routine commercial negotiation, a floor given back, a term extended, a rent reset, now has an accounting answer that can move operating profit.

The paragraphs themselves are short. Three of them cover the whole lessee model. The difficulty is not the volume of text, it is that the paragraphs sit next to a separate set of reassessment paragraphs that look similar, use some of the same mechanics, and produce different answers. Most of the errors I see in this area are not errors of arithmetic. They are errors about which paragraph the transaction belongs in. This article works through the classification first, then the mechanics, then what the accounts have to show. The rest of the standard is covered in the complete guide to IFRS 16 lease accounting, and the rate itself in the note on the incremental borrowing rate.

1. What is a lease modification under IFRS 16, and what does the definition actually exclude?

A lease modification is a change in the scope of a lease, or in its consideration, that was not part of the original terms and conditions. Adding or removing an underlying asset, and lengthening or shortening the term, are the examples the standard gives. A change the contract already provided for is not a modification, however large.

Appendix A defines a lease modification as "A change in the scope of a lease, or the consideration for a lease, that was not part of the original terms and conditions of the lease (for example, adding or terminating the right to use one or more underlying assets, or extending or shortening the contractual lease term)."

Two limbs, one qualifier. Scope, meaning what the lessee has the right to use and for how long. Consideration, meaning what the lessee pays. And the qualifier that the change was not part of the original terms and conditions, which is what separates a modification from everything else that can move a lease balance. A rent that steps up because the contract says it steps up has changed the consideration, but it was part of the original terms, so no modification has occurred. A rent that steps up because the parties sat down and agreed a new number has changed the consideration in a way the contract did not provide for, and a modification has occurred.

The bracketed examples are not a closed list, and they are not a definition. They are four common fact patterns. The test remains the two limbs plus the qualifier, applied to whatever the amendment actually did.

The standard also defines the date on which all of this happens: "The date when both parties agree to a lease modification."

Agreement, not effect. This is one of the quietest traps in the standard. A lease amendment signed on 15 December 2026 that reduces the leased floor area with effect from 1 July 2027 is accounted for on 15 December 2026. The incremental borrowing rate used is the rate at 15 December 2026. The gain under IFRS 16.46(a), if there is one, falls into the year to 31 December 2026, in a period during which the lessee is still occupying every square metre it started with. Preparers who take the accounting date from the operational date will book the whole thing a year late.

IFRS 16.36 sets out the three things that move a lease liability after commencement: interest accretes, payments reduce it, and the carrying amount is remeasured "to reflect any reassessment or lease modifications specified in paragraphs 39–46, or to reflect revised in-substance fixed lease payments (see paragraph B42)."

The drafting is worth reading slowly, because it names three separate remeasurement triggers and the standard treats them differently. Reassessment sits in IFRS 16.39 to 16.43. Modification sits in IFRS 16.44 to 16.46. Revised in-substance fixed payments sit in IFRS 16.B42 and are a third route again. Unit 2 deals with the first two. The third catches payments that are described in the contract as variable but that are unavoidable in substance, and a change in those is remeasured without the contract having been renegotiated at all.

Example: which of these four changes to the same lease is a modification?

A lessee holds a ten-year lease of a distribution unit at GBP 200,000 a year. Four things happen in different years. Only two of them are modifications.

What happenedModification?Why
Annual rent rises to GBP 214,000 under the CPI clause in the original leaseNoThe change was part of the original terms and conditions. It is a remeasurement under IFRS 16.42(b).
The lessee exercises a five-year extension option that was in the original lease and had not been included in the lease termNoStill part of the original terms. It is a change in lease term reassessed under IFRS 16.20 and remeasured under IFRS 16.40.
The parties agree to raise the rent to GBP 214,000 with no other changeYesConsideration has changed in a way the contract did not provide for. Appendix A is met.
The parties agree to add five years to the term, there being no option in the leaseYesScope has changed in a way the contract did not provide for.

Rows one and three produce the same cash. They do not produce the same accounting, and Unit 2 shows the size of the difference.

Local FAQs

Is a change that only affects payments the lessee never capitalised still a modification? Yes. The Appendix A definition turns on a change in scope or consideration, not on whether the affected payments were inside the lease liability. Renegotiating a turnover rent from three per cent of sales to two per cent changes the consideration for the lease even though neither figure was ever discounted. The liability may not move, but the contract has been modified, and the lease term, the classification of the payments and the disclosure all have to be revisited on that basis. PwC reaches the same conclusion for the equivalent ASC 842 definition.

Does a change to a non-lease component make it a modification? If the contract containing the lease is amended, the amendment is assessed under IFRS 16, and IFRS 16.45(a) sends you back to IFRS 16.13 to 16.16 to reallocate the consideration between the lease and non-lease components on relative stand-alone prices. Adding a maintenance service priced at its stand-alone price will normally leave the lease component's allocation unchanged, but the reallocation still has to be performed rather than assumed.

Is a lease surrender in full a modification? A full termination is dealt with by the same paragraph as a partial one. IFRS 16.46(a) refers to "the partial or full termination of the lease", so the entire right-of-use asset and lease liability come off and the difference, including any surrender premium, goes to profit or loss.

Potential risks

The risk that recurs most is the one in the effective date definition. Lease amendments are commonly negotiated in one period and take effect in another, and the accounting population is usually built from the property team's occupancy data rather than from the legal agreement date. That produces modifications recognised in the wrong period, and because IFRS 16.45(c) fixes the discount rate at the effective date, it also produces the wrong rate. The second risk is the reverse: treating a contractual step-up as a renegotiation because the paperwork happens to include a signed side letter confirming the new figure. Confirming a mechanism is not renegotiating it, and the original lease document, not the side letter, is the evidence.

2. What is the difference between a lease modification and a lease reassessment, and why is the usual shorthand wrong?

A reassessment updates something the original contract already contained. A modification renegotiates the contract. The shorthand that modifications use a revised discount rate and reassessments do not is wrong, because IFRS 16.41 requires a revised rate on a change in lease term, which is a reassessment. The real distinction is that only a modification can produce a gain or loss.

"After the commencement date, a lessee shall apply paragraphs 40–43 to remeasure the lease liability to reflect changes to the lease payments. A lessee shall recognise the amount of the remeasurement of the lease liability as an adjustment to the right-of-use asset. However, if the carrying amount of the right-of-use asset is reduced to zero and there is a further reduction in the measurement of the lease liability, a lessee shall recognise any remaining amount of the remeasurement in profit or loss."

Read the exception at the end, because it is the only circumstance in which a reassessment touches profit or loss. The right-of-use asset absorbs the remeasurement until it has nothing left to absorb. That happens more often than the drafting suggests: a heavily impaired retail site, or a long lease near the end of its term where the asset has depreciated faster than the liability has unwound, can carry a right-of-use asset far below the liability. A downward remeasurement then produces a credit to profit or loss that has nothing to do with IFRS 16.46(a) and is not a modification gain.

IFRS 16.40 requires the liability to be remeasured "by discounting the revised lease payments using a revised discount rate" where there is a change in the lease term as described in IFRS 16.20 to 16.21, or a change in the assessment of a purchase option. IFRS 16.41 then defines that revised rate as the interest rate implicit in the lease for the remainder of the term if readily determinable, and otherwise the lessee's incremental borrowing rate "at the date of reassessment".

This is the paragraph that breaks the common shorthand. A lessee that becomes reasonably certain it will exercise a break option it previously expected to ignore has not modified anything. Nobody has renegotiated. Yet IFRS 16.41 sends it to a fresh incremental borrowing rate, exactly as a modification would. Anyone using the discount rate as the diagnostic for whether a modification has occurred will misclassify every lease term reassessment in the portfolio.

IFRS 16.42 covers the second family of reassessments: a change in the amounts expected to be payable under a residual value guarantee, and a change in future lease payments "resulting from a change in an index or a rate used to determine those payments, including for example a change to reflect changes in market rental rates following a market rent review". IFRS 16.43 then says the opposite of IFRS 16.41: "a lessee shall use an unchanged discount rate, unless the change in lease payments results from a change in floating interest rates."

Two details are routinely missed. First, IFRS 16.42(b) says the liability is remeasured "only when there is a change in the cash flows (ie when the adjustment to the lease payments takes effect)". An index published in November that bites from the following April is not remeasured in November. Second, the paragraph expressly brings a contractual market rent review inside the reassessment family. Practitioners often assume that because a market rent review produces a negotiated number, it must be a modification. It is not, provided the review mechanism itself was in the original lease. The negotiation is about the input, not about the contract.

EventParagraphDiscount rateWhere the adjustment goes
Lease term or purchase option reassessed16.40, 16.41Revised, at the date of reassessmentRight-of-use asset (16.39)

Modification, all others16.45, 16.46(b)Revised, at the effective dateRight-of-use asset only

Read down the discount rate column and the shorthand collapses. Two of the six rows use an unchanged rate and four use a revised one, and the split does not follow the modification boundary. Read down the last column instead and the picture is clean: exactly one row can produce a gain or a loss.

Worked example 1: what does the same rent increase cost, depending on where it came from?

A lessee took a ten-year lease of a distribution unit on 1 January 2021. Rent is GBP 200,000 a year in arrears. The interest rate implicit in the lease cannot be readily determined, and the incremental borrowing rate at commencement was 5 per cent. There are no initial direct costs, incentives or dismantling obligations, so the right-of-use asset and the lease liability were both GBP 1,544,347 at commencement, and the asset is depreciated straight line over the ten-year term.

At 1 January 2026 five years remain. The lease liability is GBP 865,895 and the right-of-use asset is GBP 772,173. On that date the rent rises to GBP 214,000 for the remaining five years. The lessee's incremental borrowing rate is now 7 per cent.

Case A. The increase comes from the CPI clause in the original lease. This is IFRS 16.42(b), so IFRS 16.43 requires the original 5 per cent rate. The remeasured liability is the present value of five payments of GBP 214,000 at 5 per cent, which is GBP 926,508.

Right-of-use asset60,613
Lease liability60,613
To remeasure the lease liability for the index-linked rent increase at the unchanged discount rate of 5 per cent (IFRS 16.42(b), 16.43, 16.39).

Case B. The increase is a renegotiation, with no other change. Consideration has changed in a way the contract did not provide for, so Appendix A is met. No underlying asset has been added, so IFRS 16.44 cannot apply. Scope has not decreased, so IFRS 16.46(b) applies, and IFRS 16.45(c) requires the revised rate of 7 per cent. The remeasured liability is the present value of five payments of GBP 214,000 at 7 per cent, which is GBP 877,442.

1 January 2026, Case BDrCr
Right-of-use asset11,547
Lease liability11,547
To remeasure the lease liability for the renegotiated rent increase at the revised discount rate of 7 per cent (IFRS 16.45(c), 16.46(b)).

Same cash, same five years, same asset. The right-of-use asset ends at GBP 832,786 under Case A and GBP 783,720 under Case B, a difference of GBP 49,066, and the liability differs by the same amount. Over the remaining five years Case A carries GBP 49,066 more depreciation and Case B carries GBP 49,066 more interest, so total expense is identical and only the split between operating profit and finance cost moves. On a portfolio of several hundred leases that split is not immaterial, and it is decided entirely by which document the increase came from.

Total expense over the remaining term is the same. Bars scaled from a zero baseline at GBP 0; widths are proportionate to the balances shown.

Practitioner note

The quickest way to test a modification population is to ask for the source document behind each entry. A modification should be evidenced by a signed amendment, a deed of variation or a surrender. A reassessment should be evidenced by an index publication, a rent review memorandum or a board paper about a break option. If the same document is being used to support both classifications across different leases, one of them is wrong, and it is usually the one that produced the more convenient answer.

Local FAQs

A rent review clause says the rent will be reset to open market value, and the parties negotiate that value. Modification or reassessment? Reassessment. IFRS 16.42(b) names market rent reviews specifically. The parties are negotiating the number the original mechanism produces, not amending the mechanism. If they also agree to change the review frequency, or to add a cap, that part is a modification.

Does a rent concession that is not covid-related get the expedient? No. IFRS 16.46A and 16.46B were drafted narrowly and IFRS 16.46B(a) to (c) has to be met in full. An ordinary commercial rent holiday is assessed under Appendix A like anything else, and is normally a modification.

The right-of-use asset is already nil after impairment and the liability falls. What happens? On a reassessment, the final sentence of IFRS 16.39 sends the excess to profit or loss. On a modification under IFRS 16.46(b) the standard says to make a corresponding adjustment to the right-of-use asset, and where that would take the asset below zero the same logic applies, because an asset cannot be negative. State the treatment and the reasoning in the file, since the standard does not spell this case out for modifications.

Potential risks

The dominant risk in this unit is silent misclassification, because both routes remeasure the liability and adjust the right-of-use asset, so nothing looks obviously wrong in the ledger. Nothing reconciles, nothing fails to balance, and the error surfaces only if someone tests the rate used against the paragraph relied on. A practical control is to require the rate field and the paragraph field to be populated together in the lease system, and to exception-report every entry where a revised rate has been used with a IFRS 16.42 or 16.43 classification, or an unchanged rate with a IFRS 16.45 classification. The second risk is more subtle: an entity that is close to a gearing covenant has an incentive to classify a rent increase as a modification, because the revised rate is usually higher and the liability lands lower. That incentive should push the challenge, not the conclusion.

3. When is a lease modification accounted for as a separate lease under IFRS 16.44?

Only when both conditions in IFRS 16.44 are met. The modification must add the right to use one or more underlying assets, and the consideration must increase by an amount commensurate with the stand-alone price for that increase, adjusted for the circumstances of the contract. Fail either one and the original lease is remeasured instead.

"A lessee shall account for a lease modification as a separate lease if both: (a) the modification increases the scope of the lease by adding the right to use one or more underlying assets; and (b) the consideration for the lease increases by an amount commensurate with the stand-alone price for the increase in scope and any appropriate adjustments to that stand-alone price to reflect the circumstances of the particular contract."

Condition (a) is narrower than it first reads. It requires an underlying asset to be added. That word is defined in Appendix A as the asset subject to a lease, and the standard uses it throughout to mean the thing itself, not the period of access to it. Adding four years to the lease of a building adds no underlying asset. Adding a second building does. This is why an extension can never be a separate lease however commercially fresh it looks, and it is the single most frequently misapplied point in IFRS 16.44.

Condition (b) is where the judgement sits. "Commensurate with" is not "equal to". The standard then widens it further by allowing "appropriate adjustments to that stand-alone price to reflect the circumstances of the particular contract", which contemplates a genuine discount for the fact that the lessee is already in the building, that no marketing or void period is needed, and that the lessor faces no re-letting cost. A modest discount to headline market rent can still be commensurate. A discount that only exists because the lessee agreed to something else in the same negotiation cannot be, because the consideration for the additional space is then partly buried elsewhere.

IFRS 16.B2 requires an entity to combine two or more contracts entered into at or near the same time with the same counterparty and account for them as a single contract where any of three criteria is met: they are negotiated as a package with a single commercial objective, the consideration in one depends on the price or performance of the other, or the rights conveyed form a single lease component under IFRS 16.B32.

This paragraph is easy to forget in a modification context and it is capable of reversing the answer. A new lease of an adjacent unit, signed on the same day as a rent reduction on the existing unit, is not two independent events. If the two were negotiated as a package, IFRS 16.B2 combines them, and what looked like a clean separate lease under IFRS 16.44 becomes one modification of one combined contract, with the rent reduction on the original unit forming part of the consideration for the new space. That is precisely the fact pattern in which condition (b) fails.

Worked example 2: what if the lessee adds a floor at market rent?

Continue the four-floor office lease used later in this article. A lessee has a ten-year lease of four floors from 1 January 2021 at GBP 400,000 a year, so GBP 100,000 a floor. On 1 January 2026, with five years to run, the lessor offers a fifth floor in the same building for the remaining five years at GBP 105,000 a year. Comparable fifth-floor space in the building is letting at GBP 110,000 to GBP 115,000, and the lessor has quantified the saving on agent's fees and a void period at around GBP 5,000 a year. The lessee's incremental borrowing rate is 7 per cent.

Condition (a) is met, because a fifth floor is an additional underlying asset. Condition (b) is met, because GBP 105,000 sits inside the stand-alone range once the contract-specific saving the lessor itself has quantified is taken into account. This is a separate lease.

1 January 2026DrCr
Right-of-use asset, fifth floor430,521
Lease liability, fifth floor430,521
To recognise a separate lease of the fifth floor, being the present value of five annual payments of GBP 105,000 discounted at 7 per cent (IFRS 16.44, 16.26).

The existing four-floor lease is not touched. Its liability continues to unwind at the original 5 per cent, its right-of-use asset continues to depreciate on the original schedule, and no gain or loss arises. That is the whole point of IFRS 16.44: where the pricing is arm's length, there is nothing about the original bargain to revisit.

Change one fact and the answer changes completely. Suppose the lessor offers the fifth floor at GBP 60,000 because the lessee agreed to extend all five floors by three years. Condition (b) now fails, and IFRS 16.B2 may also combine the two limbs into one contract. The whole arrangement becomes a single non-separate modification of the existing lease, remeasured under IFRS 16.45 at 7 per cent, with the discount on the new floor spread across the entire modified liability rather than sitting on the new floor alone.

Real filer: Vodafone Group Plc on the separate lease test

Vodafone's leases accounting policy in its Form 20-F for the year ended 31 March 2026 states that "Lease modifications that increase the scope of a lease by adding the right to use one or more underlying assets in return for consideration commensurate with the stand-alone price for the additional lease components are treated as separate leases." The policy then explains that a decrease in scope causes the group to remeasure both the asset and the liability with a gain or loss recognised, and that other modifications remeasure the liability with a corresponding adjustment to the right-of-use asset. What makes this a useful benchmark is not that it repeats IFRS 16.44 to 16.46, which many policies do, but that it separates the three outcomes rather than describing modification accounting as a single process. On a lease portfolio the size of Vodafone's, with total lease liabilities of EUR 12,388 million on a discounted basis at 31 March 2026, the three outcomes have very different consequences and a policy that runs them together tells the reader nothing.

Local FAQs

The lessee added floor space in the same building. Is that one underlying asset or two? It depends on whether the space is a separate lease component under IFRS 16.B32, which asks whether the lessee can benefit from use of the space on its own or with readily available resources, and whether the space is highly dependent on or highly interrelated with the rest. Separately lettable floors normally are separate components. A wider corridor on an existing floor is not.

What evidence supports "commensurate with the stand-alone price"? Comparable lettings in the same building or immediate area at or near the effective date, an independent valuation, or the lessor's own quoted asking rent, together with an explicit quantification of any contract-specific adjustment. A statement that the rent is at market, with nothing behind it, is not evidence. The paragraph asks for a price comparison and the file needs one.

If the increase in scope is priced above stand-alone price, is it still a separate lease? IFRS 16.44(b) says the consideration must increase by an amount commensurate with the stand-alone price, and an overpricing is as much a failure of that condition as an underpricing. In practice overpricing is rare and usually signals that something else in the arrangement is being compensated, which is itself a reason to look at IFRS 16.B2.

Potential risks

The audit challenge here is almost always evidential rather than technical. Management concludes that additional space was taken at market rent, the conclusion is plausible, and there is nothing on file beyond the assertion. The consequence of getting it wrong is larger than it looks: a separate lease leaves the original liability alone, while a failed condition (b) drags the entire original lease into a remeasurement at a new rate. On a large lease that difference can be several million. The second risk is the extension error, and it is worth running as a specific test. Filter the modification population for anything described as an extension, a renewal or a reversionary lease, and confirm that none of it has been recorded as a separate lease. IFRS 16.44(a) makes that outcome impossible, so any hit is an error by definition rather than a judgement to be discussed.

4. Which discount rate applies to a lease modification, and at what date is it measured?

IFRS 16.45(c) requires the interest rate implicit in the lease for the remainder of the lease term if that rate can be readily determined, and otherwise the lessee's incremental borrowing rate at the effective date of the modification. The effective date is the date both parties agreed the change, not the date it takes physical effect.

"For a lease modification that is not accounted for as a separate lease, at the effective date of the lease modification a lessee shall: (a) allocate the consideration in the modified contract applying paragraphs 13–16; (b) determine the lease term of the modified lease applying paragraphs 18–19; and (c) remeasure the lease liability by discounting the revised lease payments using a revised discount rate."

Three instructions, and (a) and (b) are skipped far more often than (c). Sub-paragraph (a) sends the lessee back to IFRS 16.13 to 16.16 to reallocate the modified consideration between lease and non-lease components on relative stand-alone prices. Where the amendment changed a service charge as well as the rent, or bundled fit-out works into the deal, that reallocation changes the lease payments before any discounting happens. Sub-paragraph (b) requires the lease term to be determined afresh under IFRS 16.18 and 16.19, which means the reasonably certain assessment on every option in the modified contract is made again from scratch, using the facts at the effective date. A modification that shortens the non-cancellable period may make a previously ignored extension option reasonably certain, and that belongs in the modified lease term.

The rest of IFRS 16.45(c) reads: "The revised discount rate is determined as the interest rate implicit in the lease for the remainder of the lease term, if that rate can be readily determined, or the lessee's incremental borrowing rate at the effective date of the modification, if the interest rate implicit in the lease cannot be readily determined."

The hierarchy is not optional. The implicit rate comes first, and only the fact that it cannot be readily determined releases the lessee to its own borrowing rate. In practice a lessee rarely knows the lessor's unguaranteed residual value or initial direct costs, so the implicit rate is not readily determinable and the incremental borrowing rate is used. That conclusion is correct for most property leases. It is not automatically correct for equipment and vehicle leases, where the lessor's implied rate is sometimes disclosed in the schedule or derivable from a stated cash price, and a file that asserts the implicit rate is never determinable across an entire portfolio has not looked.

Note also what the paragraph does not say. It does not say the revised rate is applied to the original lease term, and it does not permit the rate at the reporting date. It is the rate for the remainder of the modified lease term, measured at the effective date. A lease modified in March and reported in December uses the March rate, even where rates have moved materially since.

Illustration: what does taking the rate on the wrong date cost?

A lessee with a 31 December year end agrees a modification on 31 March. Six annual payments of GBP 250,000 remain under the modified lease. The lessee's incremental borrowing rate for that remaining term was 5.5 per cent on 31 March and 7.5 per cent by 31 December.

Rate usedModified lease liability, GBP
5.5 per cent, the rate at the effective date, as IFRS 16.45(c) requires1,248,883
7.5 per cent, the rate at the reporting date1,173,462
Understatement of the lease liability and of the right-of-use asset75,421

Six per cent of the balance, on one lease, from a date field. The error also understates the interest charge for the rest of the lease and overstates depreciation, so it does not wash out of profit in a single period. It is invisible in the journal, because a liability discounted at the wrong rate still balances.

Practitioner note

Incremental borrowing rates for modifications are the area where lease systems most often quietly do the wrong thing. Many systems hold a single rate table by currency and term, refreshed periodically, and pick the rate in force at the date the entry is posted. That is not the same as the rate at the effective date of the modification, and in a year when rates have moved the difference is real. The test is simple. Take five modifications from across the year, ask what rate was used and what the entity's rate table said on the agreement date, and see whether they match. If the answer is that the system uses the current table, every modification in the period has been measured at the wrong rate.

Local FAQs

Does a modification change the rate on a separate lease under IFRS 16.44? No. A separate lease is a new lease measured under IFRS 16.26 using its own rate at its own commencement date. The original lease keeps its original rate, because nothing about the original lease has been remeasured.

The modification only shortens the term. Do we still need a new rate? Yes. IFRS 16.45(c) has no exception for modifications that reduce anything. The revised rate applies to the remaining payments of the modified lease. Note that a shortening agreed by renegotiation is a modification, while a shortening because the lessee has become reasonably certain to exercise an existing break clause is a reassessment under IFRS 16.20 and 16.40. Both revise the rate, but only the first can create a gain.

Can the incremental borrowing rate be set at portfolio level for modifications? IFRS 16.26 and 16.45(c) refer to the lessee's incremental borrowing rate, which Appendix A defines by reference to a similar term, similar security and a similar economic environment. A portfolio rate is a practical approximation, and it becomes harder to support on a modification, because the remaining term is usually short and short-term rates diverge most from a blended portfolio average. Where a modification leaves two years to run and the portfolio rate is built on a seven-year average, the approximation is doing real work and should be tested rather than inherited.

Potential risks

Three specific failures recur. The rate is taken at the reporting date rather than the effective date, which is a systems issue and affects every modification in the period once it exists. The lease term is not redetermined under IFRS 16.45(b), so options are carried forward on the pre-modification assessment even though the commercial position has plainly changed, which is exactly the moment IFRS 16.19 says to look again. And the consideration is not reallocated under IFRS 16.45(a) where the amendment touched a non-lease component, so service charge movements end up capitalised inside the lease liability. None of the three is visible from the journal alone, and all three are testable against the amendment document in a few minutes.

5. How do you account for a lease modification that decreases the scope of the lease?

IFRS 16.46(a) applies, in two steps. First, reduce the right-of-use asset for the part of the lease that has been terminated, reduce the lease liability for the same proportion, and put the difference in profit or loss. Second, remeasure what is left at the revised rate under IFRS 16.45(c), with that adjustment going to the right-of-use asset.

"For a lease modification that is not accounted for as a separate lease, the lessee shall account for the remeasurement of the lease liability by: (a) decreasing the carrying amount of the right-of-use asset to reflect the partial or full termination of the lease for lease modifications that decrease the scope of the lease. The lessee shall recognise in profit or loss any gain or loss relating to the partial or full termination of the lease."

The paragraph does two things at once and they are easy to run together. It requires the right-of-use asset to be decreased for the terminated part, and it requires the difference between that decrease and the corresponding decrease in the liability to hit profit or loss. What it does not do is tell you the basis on which the decrease is measured. There is no formula in the standard. The only anchor in the paragraph is the phrase "to reflect the partial or full termination", which points at the part of the right of use that has gone, rather than at the part of the liability that has gone.

The gain arises for a simple structural reason. From commencement onwards a right-of-use asset depreciates on a straight line while the liability unwinds on an effective interest basis. The liability therefore falls more slowly in the early years, and by the middle of a lease the liability normally exceeds the right-of-use asset. Removing the same proportion of each releases more liability than asset, and the excess is a gain. It is not a real economic gain, it is the reversal of an accounting mismatch that the standard created at commencement, and it is why lessees exiting space report credits in operating profit in a year when they are cutting their estate.

The direction is not universal, and a file that assumes a gain has assumed the wrong thing. Where the lessee received a large lease incentive at commencement, the right-of-use asset started below the liability and the gain is larger. Where the lessee paid a premium, capitalised significant initial direct costs under IFRS 16.24(c), or recognised a restoration provision inside the asset under IFRS 16.24(d), the right-of-use asset can sit above the liability and the same partial termination produces a loss. The sign follows the composition of the right-of-use asset at commencement, not the commercial merits of the exit.

Reading the two paragraphs in sequence gives the two-step mechanic. IFRS 16.46(a) deals with the termination. IFRS 16.45(c) deals with the remeasurement of the modified lease. Both happen on the effective date, but they are separate calculations and only the first reaches the income statement.

Order matters, and the reason is precise. If the terminated portion is measured at the revised discount rate, the effect of the rate change is swept into the gain, and a lessee whose borrowing cost has risen since commencement reports a larger gain on exit than it has actually made. Step one must therefore use the pre-modification carrying amounts, built on the original rate. The rate change belongs in step two, where IFRS 16.46(b) logic puts it against the right-of-use asset.

That is not an interpretation. The IASB's own supporting implementation webcast on lease modifications for lessees instructs preparers to "decrease pre-modification ROU asset (and pre-modification lease liability) to reflect partial or full termination" and to "calculate the partial termination of the original lease using the original discount rate", recognising any difference in profit or loss. KPMG's Lease modifications handbook presents the calculation in the same two elements, describing them as the decrease for the partial termination and, separately, the decrease in the remaining lease payments.

Worked example 3: what are the entries when a lessee gives back one of four floors?

A lessee holds a ten-year lease of four floors from 1 January 2021. Rent is GBP 400,000 a year in arrears. The interest rate implicit in the lease cannot be readily determined and the incremental borrowing rate at commencement was 5 per cent. The right-of-use asset and lease liability were both GBP 3,088,694 at commencement and the asset is depreciated straight line over ten years.

On 1 January 2026, with five years to run, the parties agree that the lessee gives back one of the four floors from that date and that rent falls to GBP 310,000 a year for the remaining five years. The lessee's incremental borrowing rate is now 7 per cent.

The rent has not fallen proportionately. Three quarters of GBP 400,000 is GBP 300,000, and the parties agreed GBP 310,000. That is deliberate and it is the common case: a lessor releasing a floor mid-term rarely does so at exactly pro-rata pricing. The extra GBP 10,000 a year is a change in consideration, and it belongs in step two, not in the gain.

One point to settle before the numbers, because it is the first thing a reviewer should ask. Step one reduces the right-of-use asset and the lease liability by the same 25 per cent of their pre-modification carrying amounts. That is what Illustrative Example 17 does, applying a 50 per cent scope reduction to both balances. The alternative framing on the liability side is to remove the present value of the payments attributable to the surrendered floor at the original rate, which is five payments of GBP 100,000 at 5 per cent. Both give GBP 432,948 here, because the original rent was level across the four floors. Where the rent is not level across the components, the two diverge and the second is the better one, since it removes what the surrendered component actually cost.

Carrying amounts immediately before the modification:

Excess of liability over asset187,444

Step one, the partial termination. One of four floors has gone, so 25 per cent of the right of use has been terminated. Reduce both carrying amounts by 25 per cent and take the difference to profit or loss.

Step two, the remeasurement. The modified liability is the present value of five payments of GBP 310,000 at the revised rate of 7 per cent, which is GBP 1,271,061. The liability after step one was GBP 1,298,843. The difference of GBP 27,782 is a reduction, and IFRS 16.46(b) logic puts it against the right-of-use asset.

Lease liability27,782
Right-of-use asset27,782

The result is worth pausing on. The lessee is now paying GBP 310,000 a year where the retained three floors were previously carried at GBP 300,000, so the annual cash outflow on the retained space has gone up. Yet the lease liability has gone down by a further GBP 27,782, because the rate used to discount it moved from 5 per cent to 7 per cent and the rate effect is larger than the payment effect. Anyone reviewing the entry who expects a rent increase to increase a liability will look at journal 2 and assume it is the wrong way round. It is not. This is exactly why IFRS 16.45(c) is the sentence that needs to be on the face of the working paper.

Two-step mechanic for a decrease in scope, showing where the gain arises and where the rate change is absorbed Worked example 3, GBP. Step one hits profit or loss. Step two does not. Both columns are drawn to the same scale from a zero baseline, so bar lengths are comparable across the two. LEASE LIABILITY Pre-modification 1,731,791 After step 1: 1,298,843 less 432,948 After step 2: 1,271,061 less 27,782 RIGHT-OF-USE ASSET Pre-modification 1,544,347 After step 1: 1,158,260 less 386,087 After step 2: 1,130,478 less 27,782 Step 1: gain of 46,861 to profit or loss 432,948 of liability released, 386,087 of asset released. Pre-modification balances, original 5 per cent rate. Step 2: nothing to profit or loss 27,782 off both sides. Equal and opposite by construction, so the move from 5 to 7 per cent never reaches the P&L. Reverse the order and the gain changes. Measure step 1 at the revised 7 per cent rate and part of the rate movement is reported as a gain on exiting the floor, which is not what IFRS 16.46(a) is measuring.
Figure 3. Worked example 3. Bar lengths are proportionate to the balances shown, on one scale across both columns. Step one releases more liability than asset, and that difference is the gain. Step two moves both by the same amount, so it cannot create one.

Firm divergence: on what basis is the right-of-use asset reduced?

IFRS 16.46(a) requires the right-of-use asset to be decreased "to reflect the partial or full termination" and stops there. It gives no measurement basis, no percentage and no formula, which is the test for a genuine gap rather than a settled paragraph.

IFRS. The Illustrative Examples accompany IFRS 16 but are not part of the standard, and Example 17 answers the question directly. A lessee holding a ten-year lease of 5,000 square metres at CU50,000 a year reduces the space to 2,500 square metres at the start of year 6, with payments falling to CU30,000 and the rate moving from 6 per cent to 5 per cent. The example determines the proportionate decrease on the basis that the remaining right of use is 50 per cent of the original, and applies that 50 per cent to both pre-modification balances: the right-of-use asset of CU184,002 is reduced by CU92,001 and the lease liability of CU210,618 by CU105,309, giving a gain of CU13,308. The remaining liability is then remeasured to CU129,884 at the revised 5 per cent rate. KPMG's Lease modifications handbook follows the same basis by reference to remaining square metres, and Deloitte's Lease modifications, ten comprehensive examples follows it on the ratio of remaining years for a shortened term. The illustration and the two largest published IFRS treatments agree.

US GAAP. ASC 842 does not agree with itself. PwC's Leases guide states there are two ways to determine the proportionate reduction in the right-of-use asset, based on either the reduction in the right-of-use asset or the reduction in the lease liability, and that a lessee should treat its chosen method as an accounting policy election by class of underlying asset, applied consistently to all modifications that decrease scope.

Where that leaves the preparer. The election exists explicitly in ASC 842 and does not exist explicitly in IFRS 16. That does not make the IFRS position free of judgement, because IFRS 16.46(a) is silent and an Illustrative Example is not a requirement. It does mean an IFRS preparer taking the liability-based approach is departing from the only illustration the IASB published, from the IASB's own implementation webcast, and from the published position of two Big 4 firms, and needs a reason. On worked example 3 the difference is not academic: the liability falls by 26.6 per cent while the right of use falls by 25 per cent, so the liability basis would reduce the right-of-use asset by GBP 410,862 rather than GBP 386,087, and the gain would be GBP 49,868 rather than GBP 46,861. GBP 3,007 on one floor of one lease, scaled across an estate. My view is that the remaining right of use is the better reading of IFRS 16.46(a), because the paragraph asks what has been terminated, and what has been terminated is a right of use, not a liability. But the file needs to say that, and say it once, as a policy applied consistently.

Real filer: Canada Goose Holdings Inc on modifications and terminations side by side

Canada Goose discloses lease modifications and lease terminations as separate lines in both its right-of-use asset and lease liability movement tables. For the year ended 29 March 2026 the cost of right-of-use assets increased by CAD 16.8 million for lease modifications and reduced by CAD 50.3 million for derecognition on termination, against which CAD 49.0 million of accumulated depreciation was released. The lease liability moved by exactly the same CAD 16.8 million for modifications. That equality is the useful signal. Where a modification adjustment is identical on both sides, it is an IFRS 16.46(b) remeasurement absorbed by the right-of-use asset, with nothing in profit or loss. In the prior year the picture differs: the right-of-use asset cost fell by CAD 23.7 million on termination with CAD 20.4 million of depreciation released, a net CAD 3.3 million, against a CAD 3.9 million liability derecognition. Reading the two tables together is the fastest way to see whether an entity has put a gain through profit or loss and how large it was, even where the income statement does not show it separately.

Local FAQs

Where in the income statement does the gain go? IFRS 16.46(a) requires it in profit or loss and says nothing more. IAS 1.85 requires additional line items where relevant to an understanding of performance, and for periods beginning on or after 1 January 2027 IFRS 18 will require classification into its defined categories. A gain from a lessee handing back trading space arises from derecognising an operating asset, not from a financing transaction, so operating profit is normally the right home. Putting it in finance income because the liability is a financial-looking balance is the error to avoid.

Is the gain the same as a termination penalty? No, and they can run in opposite directions. A penalty paid to the lessor to secure the release is consideration and is dealt with through the measurement of the lease payments, while the gain is the difference between the asset and liability derecognised. A lessee can pay a penalty and still report a net gain, which looks odd on the face of it and is a frequent subject of audit committee questions.

What if the right-of-use asset has already been impaired? Impairment under IAS 36, applied through IFRS 16.33, reduces the carrying amount before the modification, so the proportionate reduction in step one is applied to the impaired figure and the gain is correspondingly larger. Sequence matters, and the impairment test at the reporting date before the modification is the one that governs.

Potential risks

The largest single risk in this article sits here. A gain under IFRS 16.46(a) is a credit to operating profit that requires no cash and no third party to agree the amount, and it arises in exactly the years when management is under pressure on profit, because estate reduction and profit pressure travel together. It is measured on an unspecified basis, so the number is genuinely sensitive to the method chosen, and there is no external confirmation available for it. My view is that this combination is unusual enough to deserve an explicit fraud risk consideration rather than a substantive analytical procedure. Practical tests: agree the terminated proportion to the amendment rather than to a management schedule; recalculate step one on pre-modification carrying amounts and confirm the original rate was used; confirm the same basis was applied to every modification in the period; and check whether any part of the rate change has been pulled into the gain.

6. How do you account for every other lease modification, including an extension?

IFRS 16.46(b) applies to everything that is not a separate lease and not a decrease in scope. The whole remeasurement of the lease liability at the revised discount rate is made as a corresponding adjustment to the right-of-use asset. Nothing goes to profit or loss, however large the change in payments or in the rate.

"For a lease modification that is not accounted for as a separate lease, the lessee shall account for the remeasurement of the lease liability by: ... (b) making a corresponding adjustment to the right-of-use asset for all other lease modifications."

The word "corresponding" is doing the work. The adjustment to the asset equals the adjustment to the liability, so the two move together and no difference can arise. That is the structural reason the paragraph cannot generate a gain or a loss. It is not a policy choice and it is not a matter of materiality. A file showing a credit to profit or loss on a term extension has classified the transaction under IFRS 16.46(a) by mistake, or has applied a revised rate to the wrong balance.

The category is broader than it looks. It captures an extension, a rent increase, a rent decrease, a rent-free period, a change to the payment profile, a scope increase that failed the IFRS 16.44 test, and a modification adding a new underlying asset at a discount. All of them land in the same place: remeasure at the revised rate, adjust the asset, recognise nothing.

Worked example 4: what happens when the term is extended and the rent rises?

A lessee took a ten-year lease of a warehouse on 1 January 2021 at GBP 150,000 a year in arrears. The implicit rate was not readily determinable and the incremental borrowing rate at commencement was 5 per cent, so the right-of-use asset and lease liability were both GBP 1,158,260 and the asset is depreciated over ten years. There is no extension option in the lease.

On 1 January 2029, with two years to run, the parties agree to extend the term by five years and to set the rent at GBP 170,000 a year for the whole of the remaining seven years. The lessee's incremental borrowing rate is now 6.5 per cent.

Test IFRS 16.44 first. Condition (a) fails, because no underlying asset has been added. The same warehouse is being used for longer. So this cannot be a separate lease, and it never could have been, whatever the pricing.

Real filer: Ryanair Holdings plc on an aircraft lease extension

Ryanair's right-of-use asset movement table for the year ended 31 March 2025 carries a line described as "Modification of leases" of EUR 22.5 million, and the accompanying disclosure identifies the number of leased aircraft with an extended leasing term as three Airbus A320s. The line is nil in the year to 31 March 2026 and does not appear in the year to 31 March 2024. Total right-of-use assets were EUR 148.5 million at 31 March 2025 and the total lease liability was EUR 149.1 million, so the extension of three aircraft leases moved roughly 15 per cent of the balance in a single transaction. The presentation is the right one: the modification appears as an addition to the right-of-use asset rather than as an income statement item, which is what IFRS 16.46(b) requires for an extension, and it is disclosed on its own line rather than folded into additions, so a reader can see what happened without asking.

Local FAQs

Can a rent-free period be a modification? Yes, where it is agreed rather than contractual. A rent-free period granted by renegotiation changes the consideration in a way the original terms did not provide for, so Appendix A is met, IFRS 16.45(c) requires a revised rate, and IFRS 16.46(b) puts the whole adjustment into the right-of-use asset. The liability falls and the asset falls with it. No credit to profit or loss arises, which surprises preparers who expect a rent holiday to show up as a saving in the year it is granted.

The modification adds an asset but at a heavy discount. Where does it go? IFRS 16.44 fails at condition (b), so the whole arrangement, including the new asset, is one modification of the existing lease under IFRS 16.45. The lease term is determined for the modified contract, the consideration is reallocated across all lease components, and the entire remeasured liability is discounted at one revised rate. Deloitte's Lease modifications, ten comprehensive examples works this fact pattern through in detail, and notes that where the added space is made available at the effective date and both components carry the same rate and term, the allocation between them does not change the totals.

What if the extended term makes the right-of-use asset unrecoverable? IFRS 16.33 applies IAS 36 to right-of-use assets, and a modification that increases the carrying amount of the asset by GBP 653,457 in one entry is an indicator worth testing. The remeasurement itself does not trigger an impairment test automatically, but the resulting carrying amount has to be recoverable, and a lessee extending a lease on premises it is not using is exactly the case where it will not be.

Potential risks

Two things go wrong here. The first is a gain appearing where none can exist, usually because a modification that both extends the term and reduces the floor area has been treated as a single IFRS 16.46(b) remeasurement rather than being split as Unit 7 sets out, or because the preparer has calculated the difference between the old and new liability using two different rates and taken part of it to profit or loss. The second is the depreciation period. A modification changes the lease term, and the right-of-use asset has to be depreciated over the modified term from the effective date under IFRS 16.32. Lease systems frequently remeasure the liability correctly and leave the depreciation schedule on the original term, which understates or overstates the charge for the rest of the lease and is invisible in the modification journal itself.

7. What happens when one amendment both increases and decreases the scope of a lease?

The two effects are not netted. Test any increase in scope against IFRS 16.44 first and account for anything that qualifies as a separate lease on its own. What remains is one modification, and the decrease in scope goes through IFRS 16.46(a) with its gain or loss before the balance reaches the right-of-use asset.

IFRS 16 does not contain a paragraph on combined modifications, and that absence is itself the instruction. IFRS 16.44 asks a question about the separate lease and is answered first, because it determines whether there is one contract or two to account for. IFRS 16.45 then applies to whatever was not a separate lease, in one remeasurement at one revised rate. IFRS 16.46 then splits the result of that single remeasurement between (a) and (b) according to whether scope decreased.

The mistake is to treat a mixed amendment as two independent modifications and remeasure twice. There is one modified contract, one modified lease term determined under IFRS 16.45(b), and one revised discount rate under IFRS 16.45(c). What is split is not the remeasurement but its accounting destination.

The other mistake is netting. A lessee that gives back one floor and extends the remaining three has not made a neutral change. It has terminated part of a lease, which IFRS 16.46(a) requires to be recognised in profit or loss, and extended the rest, which IFRS 16.46(b) requires to be absorbed by the asset. Netting them suppresses the gain and misstates operating profit.

Worked example 5: what if the lessee gives back a floor and extends the rest?

Take the four-floor lease from worked example 3 again. Ten years from 1 January 2021, rent GBP 400,000 a year in arrears, incremental borrowing rate 5 per cent at commencement, right-of-use asset and lease liability GBP 3,088,694 at commencement. At 1 January 2026 the liability is GBP 1,731,791 and the asset is GBP 1,544,347.

This time the parties agree two things on 1 January 2026. The lessee gives back one of the four floors, and the term on the remaining three floors is extended by four years, so nine years now run from 1 January 2026. Rent for the modified lease is GBP 300,000 a year. The lessee's incremental borrowing rate is 7 per cent.

IFRS 16.44 is tested first and fails at condition (a), because nothing has been added. There is one modification.

Step one, the decrease in scope. One of four floors has been terminated, so 25 per cent of the right of use has gone. This is measured on the pre-modification carrying amounts, at the original rate, exactly as in worked example 3.

The increase of GBP 655,727 is the combined effect of the four extra years and the rate change, and IFRS 16.46(b) sends all of it to the right-of-use asset.

Note the shape of the answer. The lessee has reduced its estate by a quarter and its lease liability has gone up, from GBP 1,731,791 to GBP 1,954,570, because four extra years on three floors outweighs one floor released for five. At the same time it reports a gain of GBP 46,861 in operating profit. A reader looking only at the income statement sees a credit; a reader looking only at the balance sheet sees a larger commitment. Both are correct, and the disclosure has to let a reader see both, which is the subject of Unit 10.

Sequencing. If step two were performed first, the whole movement would be an IFRS 16.46(b) adjustment to the right-of-use asset and the GBP 46,861 gain would disappear. If the terminated portion were measured at 7 per cent instead of 5 per cent, the gain would change. Neither is a presentational nicety. The order and the rate together determine what appears in operating profit, and both should be stated on the face of the working paper rather than left implicit in a spreadsheet.

Local FAQs

What if the amendment adds a genuinely new asset at market rent and shortens the term on an existing one? Split them. The addition meets IFRS 16.44 and is a separate lease measured on its own. The shortening is a modification of the original lease under IFRS 16.46(a). The two are accounted for independently, and IFRS 16.B2 should be considered to confirm the pricing of each really is independent rather than the product of one package negotiation.

Does the order matter if scope only decreases? Yes, and worked example 3 shows why. Even with no increase in scope, running the termination and the remeasurement together lets the rate change into the gain.

Can a single amendment produce both a gain and a separate lease? Yes. A lessee surrendering one building and taking another at arm's length rent in the same deed will recognise a gain on the surrender under IFRS 16.46(a) and a new lease under IFRS 16.44, provided IFRS 16.B2 does not combine the two limbs. If it does, there is one contract and no separate lease.

Potential risks

Combined amendments are where the lease system is most likely to be overridden manually, and manual overrides in this area are rarely documented to the standard the transaction deserves. Ask for the calculation rather than the journal. The specific things to look for are a single net entry with no split between IFRS 16.46(a) and 16.46(b), a gain calculated on post-modification rather than pre-modification carrying amounts, and a modified lease term that has not been redetermined under IFRS 16.45(b) across all the components in the amended contract.

8. How does a lessor account for a lease modification under IFRS 16?

It depends on classification. IFRS 16.79 gives finance lease lessors the same separate lease test as lessees. IFRS 16.80 then routes a non-separate modification either to new lease accounting or to IFRS 9. IFRS 16.87 gives operating lease lessors one rule: account for the modification as a new lease from its effective date, carrying forward prepaid and accrued amounts.

"A lessor shall account for a modification to a finance lease as a separate lease if both: (a) the modification increases the scope of the lease by adding the right to use one or more underlying assets; and (b) the consideration for the lease increases by an amount commensurate with the stand-alone price for the increase in scope and any appropriate adjustments to that stand-alone price to reflect the circumstances of the particular contract."

Word for word the lessee test in IFRS 16.44. That symmetry is deliberate and it is the only part of the lessor model that mirrors the lessee model. Everything after it diverges, because the lessor never had a right-of-use asset to adjust.

For a finance lease modification that is not a separate lease, IFRS 16.80 requires: "(a) if the lease would have been classified as an operating lease had the modification been in effect at the inception date, the lessor shall: (i) account for the lease modification as a new lease from the effective date of the modification; and (ii) measure the carrying amount of the underlying asset as the net investment in the lease immediately before the effective date of the lease modification. (b) otherwise, the lessor shall apply the requirements of IFRS 9."

This is the paragraph that has no lessee equivalent and it is routinely skipped. The lessor has to re-run the classification test in IFRS 16.61 to 16.66 on the modified terms, but as at the inception date, not at the modification date. If the modified lease would have been an operating lease on the original facts, the finance lease receivable is derecognised and an asset is brought back onto the balance sheet at the carrying amount of the net investment, and operating lease accounting begins.

If the modified lease would still have been a finance lease, IFRS 16 hands the whole calculation to IFRS 9. That is a significant redirection. The lessor's net investment is a financial asset, and a modification of it engages the IFRS 9.5.4.3 modification mechanics and, where the change is substantial enough, the IFRS 9.3.2.3 derecognition test. Extending a finance lease is therefore not the mirror image of the lessee's IFRS 16.46(b) adjustment. It is a financial asset modification question with a different threshold and a different answer.

"A lessor shall account for a modification to an operating lease as a new lease from the effective date of the modification, considering any prepaid or accrued lease payments relating to the original lease as part of the lease payments for the new lease."

One sentence, no separate lease test, no classification reassessment, no gain or loss. Everything is prospective. The practical consequence sits in the second half of the sentence. An operating lessor recognises income on a straight-line basis under IFRS 16.81, so a lease with stepped rents or a rent-free period carries an accrued or deferred balance. On modification that balance is not written off. It is folded into the lease payments of the new lease and released over the modified term. A lessor that clears it to profit or loss on modification has accelerated income that IFRS 16.87 requires to be spread.

Party and classificationSeparate lease test?If not a separate leaseCan a gain or loss arise?
Lessee, any leaseYes, IFRS 16.44Remeasure at a revised rate, IFRS 16.45Only on a decrease in scope, IFRS 16.46(a)
Lessor, finance leaseYes, IFRS 16.79New lease if it would have been operating at inception, otherwise IFRS 9, IFRS 16.80Yes, through the IFRS 9 route
Lessor, operating leaseNoAccount for as a new lease from the effective date, IFRS 16.87No, everything is prospective

The asymmetry is real and it is not a drafting accident. The same amendment to the same building can produce a gain in the lessee's operating profit under IFRS 16.46(a) and nothing at all in the lessor's, because IFRS 16.87 is entirely prospective. Anyone reconciling the two sides of a group's intra-group leases needs to expect that, rather than treat it as an error.

Regulatory source: the IFRS Interpretations Committee on lessor forgiveness of lease payments

The Committee published an agenda decision on Lessor Forgiveness of Lease Payments (IFRS 9 and IFRS 16), finalised at its September 2022 meeting and not objected to by the IASB in October 2022. The fact pattern is an operating lessor legally releasing a lessee from specifically identified payments, some already contractually due and recognised as operating lease receivables with the income already taken, and some not yet due. No other terms changed.

The Committee concluded that the two populations are accounted for differently. Amounts already recognised as operating lease receivables are financial assets within IFRS 9 by virtue of IFRS 9.2.1(b)(i), so the forgiveness is a derecognition question under IFRS 9.3.2.3(a), the contractual rights to the cash flows having expired. Future payments not yet due are dealt with under the IFRS 16 lease modification requirements, which for an operating lessor means IFRS 16.87. The Committee also confirmed that before the concession is granted, IFRS 9.5.5.17 requires the lessor's expected credit loss measurement on those receivables to reflect reasonable and supportable information about the forgiveness it expects to grant.

The point that transfers beyond the specific facts is the split. A single commercial act of forgiveness is not a single accounting event. It falls across two standards depending on whether the payment had already become a receivable, and a lessor that runs the whole concession through IFRS 16.87 will have derecognised a financial asset without applying IFRS 9 to it.

Local FAQs

Does a lessor reassess lease classification when an operating lease is modified? IFRS 16.87 tells the lessor to account for the modification as a new lease from the effective date, and a new lease is classified under IFRS 16.61 to 16.66 on its own terms. So the classification of the modified lease is determined, and an operating lease can become a finance lease on modification where, for example, a substantial extension now covers the major part of the remaining economic life.

An intermediate lessor subleases space it holds under a head lease. Which set of rules applies? Both, separately. The head lease modification is accounted for as a lessee under IFRS 16.44 to 16.46, and the sublease modification is accounted for as a lessor under IFRS 16.79, 16.80 or 16.87 depending on the sublease's classification. IFRS 16.B58 classifies a sublease by reference to the right-of-use asset arising from the head lease rather than the underlying asset, and a head lease modification that shortens the term can therefore change the sublease's classification as a knock-on effect.

Can a lessor recognise a gain on a finance lease modification? Through IFRS 16.80(b) and IFRS 9, yes. If the modification is substantial enough to fail the IFRS 9.3.2.3 derecognition test, the existing net investment is derecognised and a new one recognised at fair value, with the difference in profit or loss. If it is not substantial, IFRS 9.5.4.3 requires the gross carrying amount to be recalculated at the original effective interest rate with the difference recognised immediately. Either way there is an income statement effect, which is the opposite of the operating lessor answer.

Potential risks

Lessor modification accounting is under-audited relative to lessee accounting, because IFRS 16 changed so little for lessors that the area is often assumed to be unchanged from IAS 17. Two things did change. IFRS 16.80 introduced a route into IFRS 9 that IAS 17 did not have, and it is frequently missed entirely, with finance lease extensions being accounted for by simply re-running the amortisation schedule. And the accrued or deferred straight-line balance under IFRS 16.87 is written off on modification more often than it is carried forward, which pulls income into the wrong period. Both are testable directly against the paragraph.

9. Is the covid-19 rent concession expedient in IFRS 16.46A still available, and what about benchmark reform?

No. IFRS 16.46B(b) limits the covid-19 expedient to concessions where any reduction affects only payments originally due on or before 30 June 2022, and that window has closed. The interest rate benchmark reform expedient in IFRS 16.105 has no expiry date and remains available, but only for modifications that reform actually required.

IFRS 16.46A: "As a practical expedient, a lessee may elect not to assess whether a rent concession that meets the conditions in paragraph 46B is a lease modification. A lessee that makes this election shall account for any change in lease payments resulting from the rent concession the same way it would account for the change applying this Standard if the change were not a lease modification."

IFRS 16.46B sets three conditions, all of which must be met: the change results in revised consideration that is substantially the same as, or less than, the consideration immediately preceding the change; "any reduction in lease payments affects only payments originally due on or before 30 June 2022"; and there is no substantive change to other terms and conditions of the lease.

Condition (b) is the one that matters now. It is a fixed calendar date written into the standard, not a rolling window, and every payment that was originally due on or before 30 June 2022 has long since fallen due. A rent concession negotiated today cannot satisfy it. The paragraphs are still in the standard and they still govern how a company accounted for concessions in 2020, 2021 and 2022, but as a live accounting option the expedient is finished.

The history is worth knowing because published guidance on this subject is inconsistent about it. The original amendment, issued in May 2020, set the date at 30 June 2021. A further amendment in 2021 extended it to 30 June 2022, which is the version now in the standard. Firm publications written in 2020, including EY's Applying IFRS: Accounting for covid-19 related rent concessions of July 2020, describe the 30 June 2021 limit throughout, because that was the position when they were written. Anyone reading a 2020 publication today is reading a superseded date, and anyone describing the expedient as currently available is describing a position that no longer exists.

IFRS 16.60A requires a lessee that applied the expedient to disclose that it applied it to all rent concessions meeting the IFRS 16.46B conditions, or information about the nature of the contracts if it did not, and "the amount recognised in profit or loss for the reporting period to reflect changes in lease payments that arise from rent concessions to which the lessee has applied the practical expedient".

This paragraph is now dormant for current periods. It is worth reading anyway, because it shows what the IASB thought was needed when a lease change produces an income statement effect: the amount, disclosed separately, in the period. There is no equivalent requirement anywhere in IFRS 16 for the gain that arises under IFRS 16.46(a) on an ordinary partial termination, which is the subject of Unit 10.

IFRS 16.105 provides a different expedient with no expiry: "As a practical expedient, a lessee shall apply paragraph 42 to account for a lease modification required by interest rate benchmark reform." A modification is required by reform only if both conditions in that paragraph hold, namely that the modification is a direct consequence of the reform and the new basis for determining the lease payments is economically equivalent to the previous basis.

Note the wording. IFRS 16.105 says a lessee "shall" apply IFRS 16.42, so it is not optional where it applies. The consequence is that the change is treated as a remeasurement under IFRS 16.42 rather than as a modification, and IFRS 16.43 then supplies a revised rate reflecting the change in the interest rate rather than a fresh incremental borrowing rate. IFRS 16.106 closes the obvious gap: where other modifications are made at the same time as the reform-driven one, the ordinary requirements apply to all of them together.

This matters most for leases with payments indexed to a benchmark that was replaced. The condition to watch is economic equivalence. A transition from a benchmark to a replacement rate plus a spread adjustment designed to preserve value normally meets it. A transition that also resets the margin, or changes the payment dates, does not, and the whole change falls back into IFRS 16.44 to 16.46.

Local FAQs

We applied the expedient in 2021 and 2022. Do the comparatives change now? No. The expedient was validly applied when the conditions were met, and IFRS 16.46A is not withdrawn. Nothing is restated. The only current consequence is that a rent concession negotiated now is assessed on ordinary principles, so the accounting for two economically similar concessions three years apart is different, and the accounting policy note should say why rather than leaving the reader to work it out.

Is a deferral of rent, with no reduction, a modification at all? A pure deferral that leaves total consideration unchanged still changes the timing of the lease payments, so it changes the consideration for the lease in present value terms and meets the Appendix A definition where it was not provided for in the contract. It is normally remeasured under IFRS 16.45 at a revised rate, and because the total cash is unchanged the effect is small but not nil.

Does the benchmark reform expedient apply to a lease that was renegotiated at the same time for commercial reasons? IFRS 16.106 answers this directly. Where modifications are made in addition to the reform-driven one, the lessee applies the ordinary requirements of the standard to all of them, including the reform-driven part. The expedient does not survive being bundled with a commercial renegotiation.

Potential risks

The risk here is guidance drift rather than judgement. A large volume of firm material, training content and software documentation on IFRS 16 rent concessions was written between May 2020 and 2021, and much of it still carries the 30 June 2021 date and describes the expedient as an available election. A preparer researching a current concession will find that material first. The control is to read IFRS 16.46B in the currently effective standard rather than any summary of it, and to date every source used in the file. The second risk is on the reform expedient: economic equivalence in IFRS 16.105(b) is a real test with a real threshold, and applying the expedient to a change that also moved the margin removes a revised discount rate that the standard required.

10. What does IFRS 16 actually require a company to disclose about lease modifications?

Almost nothing specific. IFRS 16.53 lists ten amounts a lessee must disclose and a modification gain is not one of them, although a sale and leaseback gain is. The requirement therefore comes from the disclosure objective in IFRS 16.51, the additional information requirement in IFRS 16.59, and IAS 1.97 on material items.

IFRS 16.51 sets the objective: disclosure that "gives a basis for users of financial statements to assess the effect that leases have on the financial position, financial performance and cash flows of the lessee".

IFRS 16.53 then lists the amounts required, in a tabular format under IFRS 16.54. Depreciation by class of underlying asset, interest on lease liabilities, short-term and low-value lease expense, variable lease payments, sublease income, total cash outflow for leases, additions to right-of-use assets, "gains or losses arising from sale and leaseback transactions", and the closing carrying amount of right-of-use assets by class.

Read the list again and notice what is not on it. A gain or loss on a lease modification is not a required disclosure. The IASB required the sale and leaseback gain in IFRS 16.53(i) and did not require the modification gain, even though both are non-cash credits arising from a lease transaction and the modification gain is far more common. Nor does the standard require a movement table for right-of-use assets, only additions and a closing balance, which means a company can comply with IFRS 16.53 in full while showing a reader nothing at all about a material modification.

IFRS 16.59 requires "additional qualitative and quantitative information about its leasing activities necessary to meet the disclosure objective in paragraph 51", and lists the nature of the leasing activities, future cash outflows not reflected in the lease liabilities, restrictions or covenants, and sale and leaseback transactions as examples of what that might include.

This is where a material modification actually belongs, and IFRS 16.59 is a requirement rather than an encouragement. Where a company has restructured a material part of its estate, the objective in IFRS 16.51 is not met by a closing balance. Alongside it, IAS 1.97 requires the nature and amount of material items of income and expense to be disclosed separately, and IAS 1.122 requires disclosure of the judgements management has made that have the most significant effect on the amounts recognised. For periods beginning on or after 1 January 2027, IFRS 18 supersedes IAS 1 (IFRS 18.C1 and C8) and adds a classification requirement to the presentation question, which the local FAQ below deals with.

Real filer: ZIM Integrated Shipping Services Ltd, where the largest movement has no name

ZIM's right-of-use asset movement table for the year ended 31 December 2025 shows a line called "Other" of USD 789.6 million, of which USD 794.0 million relates to vessels. The disclosure explains that the "Other" line consists mainly of lease modifications and terminations. Set that against the rest of the table: additions were USD 311.1 million and depreciation was USD 1,169.6 million, on a closing right-of-use asset of USD 5,695.5 million. Modifications and terminations were therefore more than twice the size of all new leases entered into during the year, and the single largest positive movement in the balance. The reader is told the line exists and roughly what is in it, and is told nothing about how much of it was a modification rather than a termination, what the gain or loss was, or which vessels were involved. Nothing in IFRS 16.53 requires more. That is the point: on the largest lease modification activity in the filing, the standard's specific disclosure list is silent, and the only paragraphs that reach it are the objective in IFRS 16.51 and the additional information requirement in IFRS 16.59.

Real filer: WPP plc, and the same gap in a different sector

WPP's right-of-use asset movement table for the year ended 31 December 2025 shows additions of GBP 199 million, disposals of GBP 46 million, depreciation of GBP 201 million and impairment charges of GBP 28 million, against a closing balance of GBP 1,317 million. The lease liability table shows additions of GBP 192 million and disposals of GBP 59 million against a closing balance of GBP 1,896 million. There is no modification line in either table. For a group that has been consolidating its office estate over several years, and whose right-of-use asset has fallen from GBP 1,385 million to GBP 1,317 million while its lease liability fell from GBP 2,020 million to GBP 1,896 million, modifications are unlikely to be nil. Where they are not separately labelled, a reader cannot tell whether the movement described as disposals is a full exit, a partial termination, or a remeasurement, and the three have different consequences for future cash outflows.

Practitioner note: reading a lease note for modifications in ninety seconds

Put the right-of-use asset movement table next to the lease liability movement table and compare the modification line in each.

If the two are equal, the modifications in the period were IFRS 16.46(b) remeasurements absorbed by the asset, and nothing went to profit or loss. Canada Goose's tables show exactly this for the year ended 29 March 2026: CAD 16.8 million on both sides.

If the liability line is larger than the asset line, there was a decrease in scope and the difference is the gain under IFRS 16.46(a). Look for it in operating profit and ask whether it was disclosed.

If there is no modification line at all, as at WPP, the movements are inside additions, disposals or a line called Other, and the only way to size them is to ask.

The whole test takes a couple of minutes and it tells you more about a company's lease accounting than the accounting policy note does.

Local FAQs

Where should a modification gain be presented in the income statement? Under IAS 1, which remains the effective standard for periods before 1 January 2027, IAS 1.85 permits and IAS 1.97 requires additional presentation and disclosure for material items. Under IFRS 18, effective for periods beginning on or after 1 January 2027, the answer becomes more precise. A lease liability is a liability arising from a transaction that does not only involve the raising of finance, so IFRS 18.59(b) applies. IFRS 18.61 then confines the financing category for such liabilities to interest income and expenses and to income and expenses arising from changes in interest rates. A gain under IFRS 16.46(a) is neither, because the two-step mechanic deliberately keeps the rate change out of it. IFRS 18.52 makes the operating category the residual, so the gain is classified as operating. My view is that operating is also the right answer under IAS 1 today, and that companies presenting modification gains within finance income are anticipating a classification that IFRS 18 will not give them.

Does a modification need to be disclosed as a significant judgement? The classification decision itself often does. Whether a change is a modification or a reassessment, whether IFRS 16.44(b) was met, and the basis chosen for the proportionate reduction under IFRS 16.46(a) are all judgements that change reported numbers, and IAS 1.122 requires disclosure of judgements that have the most significant effect on the amounts recognised.

Is a movement table for right-of-use assets required? Not by IFRS 16.53, which requires only additions and the closing carrying amount by class. Most companies present one anyway, because IFRS 16.51 is difficult to meet without it and because users expect the same rollforward they get for property, plant and equipment under IAS 16.73(e). The absence of a mandatory rollforward is the structural reason modification disclosure is as thin as it is.

Potential risks

The audit risk in this unit is that compliance and usefulness have come apart. A lease note can tick every item in IFRS 16.53 and leave a reader unable to tell that a company recognised a material credit in operating profit from handing back property. Because IFRS 16.53 does not name the gain, a challenge has to be built on IFRS 16.51 and IFRS 16.59 and on IAS 1.97, which is a harder conversation and is therefore had less often than it should be. The practical test is to take the modification gain recognised in the period, compare it with the entity's own materiality, and ask where a reader would find it. If the answer is nowhere, IFRS 16.51 has not been met however complete the IFRS 16.53 table is.

11. How do lease modifications differ between IFRS 16 and ASC 842?

The separate contract test is nearly identical and so is the basic split between a scope decrease and everything else. The differences sit around them: ASC 842 reassesses lease classification on modification, makes the basis for reducing the right-of-use asset an explicit policy election, and treats a future-dated partial termination as a term reduction with no gain.

ASC 842-10-25-8 accounts for a modification as a separate contract on the same two conditions IFRS 16.44 uses: the modification grants an additional right of use not included in the original lease, and the consideration increases commensurately with the stand-alone price of that additional right of use, adjusted for the circumstances of the contract. A preparer moving between frameworks can rely on this test producing the same answer.

The ASC 842 Glossary definition of a lease modification is also close to the IFRS 16 Appendix A definition: "A change to the terms and conditions of a contract that results in a change in the scope of or the consideration for a lease". PwC notes that the US guidance does not distinguish between significant and insignificant changes, and that modified terms negotiated between third parties should generally be presumed substantive.

ASC 842-10-25-9 requires the lease classification to be reassessed on a modification that is not accounted for as a separate contract. This has no counterpart in the IFRS 16 lessee model, because IFRS 16 does not classify lessee leases at all. A US GAAP lessee can therefore find that an operating lease has become a finance lease on modification, which changes the shape of the income statement from a single lease cost to separate amortisation and interest, and changes the operating and financing split in the cash flow statement.

EY's Financial reporting developments: Lease accounting sets out the consequence where a finance lease becomes an operating lease on modification: the difference between the right-of-use asset after applying ASC 842-10-25-12 or 25-13 and the amount that would result from initial operating lease measurement under ASC 842-20-30-5 is accounted for in the same way as a rent prepayment or a lease incentive. There is nothing to translate here, because IFRS 16 has no such transition to make.

ASC 842-10-25-13 requires a lessee to decrease the carrying amount of the right-of-use asset in proportion to the full or partial termination of the lease, with any difference between the adjustments recognised in profit or loss at the effective date of the modification. That is the same mechanic as IFRS 16.46(a), including the two-step sequence: EY's Illustration 4-6 shows the reduction in proportion to the reduction in space first, producing the gain, and the change in consideration and revised discount rate second.

Where the frameworks part company is the measurement basis. Both PwC and EY confirm that a lessee under ASC 842 may remeasure the right-of-use asset based on either the change in the lease liability or the remaining right of use, and PwC describes that choice as an accounting policy election by class of underlying asset that must be applied consistently. IFRS 16 contains no such election in the text of the standard, and Illustrative Example 17 works the calculation on the remaining right of use, applying that proportion to both the right-of-use asset and the lease liability.

This is the divergence most likely to produce different numbers on the same facts. EY states that where a lease is modified to fully or partially terminate at a future date, rather than contemporaneously with the effective date of the modification, the change is effectively a reduction in the lease term, and a lessee should apply ASC 842-10-25-11(b) and 25-12. Under ASC 842-10-25-12 the whole remeasurement is an adjustment to the right-of-use asset, with nothing in profit or loss.

IFRS 16 does not draw that line. Appendix A names "shortening the contractual lease term" as an example of a lease modification, and IFRS 16.46(a) applies to any modification that decreases the scope of the lease, with no carve-out for a decrease that takes effect later. Combined with the Appendix A definition of the effective date as the date the parties agree, an IFRS lessee agreeing in December 2026 to hand back a floor in July 2027 recognises the gain in 2026, while a US GAAP lessee on EY's reading recognises no gain at all and adjusts the right-of-use asset instead. Same deal, same dates, two different income statements.

Local FAQs

Does IFRS 16 have the ASC 842 rule about the right-of-use asset falling below zero on a modification? ASC 842-10-25-12 says the excess goes to profit or loss once the right-of-use asset is reduced to zero. IFRS 16 states that rule in IFRS 16.39, which sits in the reassessment paragraphs, and does not repeat it in IFRS 16.46(b). The outcome should be the same, because an asset cannot be negative, but the IFRS reasoning has to be constructed rather than cited, and a file taking that position should say so explicitly.

What about FRS 102? The FRC's periodic review moved UK GAAP to an on-balance-sheet lessee model in a revised Section 20, effective for periods beginning on or after 1 January 2026, with early application permitted if the other periodic review amendments are applied at the same time. A UK entity reporting for the calendar year 2026 is applying it now. The architecture is the same as IFRS 16: a modification is a separate lease where it adds the right to use one or more underlying assets and the change in price is commensurate with the stand-alone price, and otherwise the lease liability is remeasured with the adjustment made to the right-of-use asset. A change in the lease term or in the assessment of a purchase option uses a revised rate; a change in the amounts expected under a residual value guarantee uses an unchanged rate. Two differences matter. FRS 102 allows an obtainable borrowing rate as well as an incremental borrowing rate, which IFRS 16 does not, and EY's analysis of the periodic review notes that FRS 102 permits an unchanged discount rate in some modification circumstances where IFRS 16.45(c) requires a revised one. A group running both frameworks should expect different liabilities on the same amendment.

Which framework produces the larger gain on a scope decrease? Neither, systematically. On a contemporaneous partial termination the mechanics are the same and the difference comes only from the basis chosen for the right-of-use asset reduction, which ASC 842 lets a company elect. Where the two genuinely part is the future-dated termination, where IFRS 16 produces a gain and ASC 842 on EY's reading produces none.

Potential risks

Groups reporting under both frameworks, or under one framework with a US parent reporting under the other, are exposed here in a way that is easy to miss because the two standards look so similar. The separate contract test agreeing on almost every fact pattern creates a false confidence that the rest agrees too. The specific items to reconcile are the classification reassessment, the basis elected for right-of-use asset reductions, and the treatment of amendments that take effect after the date they are agreed. All three are policy-level differences, so they should be documented once at group level rather than resolved lease by lease.

What have regulators and the Interpretations Committee actually said about lease modifications?

Two sources are directly on point. The IFRS Interpretations Committee's 2022 agenda decision on lessor forgiveness of lease payments splits a single concession across IFRS 9 and IFRS 16. The FRC's 2020 thematic review on IFRS 16 disclosures asked companies to tailor their policies and to explain the significant judgements behind their lease accounting.

What did the Interpretations Committee decide on lessor forgiveness in September 2022?

The Committee finalised its agenda decision on Lessor Forgiveness of Lease Payments (IFRS 9 and IFRS 16) at its September 2022 meeting, and the IASB did not object at its October 2022 meeting. Unit 8 sets out the conclusion. The wider point for anyone working on modifications is that the Committee did not answer the question by choosing one standard. It divided the transaction: payments already recognised as operating lease receivables are financial assets, so their forgiveness is an IFRS 9 derecognition question, while payments not yet due are dealt with under the IFRS 16 modification requirements. It also confirmed that expected credit losses on those receivables must already reflect reasonable and supportable information about forgiveness the lessor expects to grant, which means the accounting starts before the concession is signed.

Agenda decisions are not amendments and do not carry an effective date, but they explain how the requirements already apply. A lessor that accounted for a whole concession as a single IFRS 16.87 event has an accounting policy that this decision does not support.

What did the FRC ask companies to improve in its September 2020 IFRS 16 review?

The FRC published a thematic review of IFRS 16 disclosures in the first year of application in September 2020. It found that most companies gave a good explanation of the impact of adopting the standard, and set out what it expected companies to do next: to "tailor the descriptions of their leasing accounting policies to match their particular circumstances and to cover all material areas", to "provide detailed information about the significant judgements affecting their accounting for leases", and to "include sufficient detail to enable a good understanding of the financial reporting effects of their leasing arrangements on their financial position, financial performance and cash flows".

Modifications sit squarely inside all three. The classification decision between a modification and a reassessment, the IFRS 16.44(b) conclusion on stand-alone price, and the basis used to reduce the right-of-use asset under IFRS 16.46(a) are significant judgements that change reported numbers. A policy note that repeats the paragraphs without saying which judgements the company actually made, or how, is exactly the practice the review addressed. Unit 10 shows how thin the specific disclosure requirement is, which is why the general expectations in this review carry more weight here than they do in areas the standard itself covers in detail.

Scope note. The review addressed first-year adoption disclosures rather than modifications specifically, and it predates most of the modification activity discussed in this article. It is cited for the disclosure expectations it sets out, which are general and remain the FRC's stated position, not as a finding about modification accounting. The three expectations quoted are taken from the FRC's own announcement of the review on 24 September 2020.

Six ways lease modification accounting goes wrong

  • Using the discount rate to decide whether a modification has occurred. This is the error that prompted the rewrite of this page. A revised rate is required by IFRS 16.45(c) on a modification and by IFRS 16.41 on a lease term reassessment, so the rate tells you nothing about which one you are in. Work from the Appendix A definition and ask whether the original contract provided for the change. The consequence of getting it backwards is not just a wrong rate. A reassessment misclassified as a scope decrease produces a gain that IFRS 16.39 does not allow.
  • Accounting for the modification on the date it takes effect. Appendix A fixes the accounting on the date both parties agree. Amendments negotiated in one period and operative in another are recognised in the period of agreement, at the rate prevailing then. Populations built from occupancy data rather than from executed agreements get this wrong systematically rather than occasionally.
  • Recognising a gain on an extension. IFRS 16.46(b) makes a corresponding adjustment to the right-of-use asset, so the two sides move by the same amount and no difference can arise. Any gain on a modification that did not decrease scope is an arithmetic error or a misclassification, not a judgement.
  • Measuring the terminated portion at the revised discount rate. Step one of IFRS 16.46(a) derecognises part of the pre-modification lease and has to be built on pre-modification carrying amounts at the original rate. Using the new rate pulls the effect of the rate change into the gain, which inflates it whenever borrowing costs have risen since commencement. In worked example 3 the entire step-two movement was driven by the rate, and it was a reduction of GBP 27,782 that belonged in the right-of-use asset.
  • Remeasuring the liability and leaving the depreciation schedule alone. IFRS 16.45(b) redetermines the lease term and IFRS 16.32 depreciates the right-of-use asset over it. Systems that post the remeasurement journal correctly but keep amortising over the original term produce a charge that is wrong for every remaining period, and nothing in the modification journal reveals it.
  • Treating an extension as a possible separate lease. IFRS 16.44(a) requires an underlying asset to be added. More time on the same asset is not an additional asset, so the separate lease outcome is unavailable however commercial the pricing. This is worth running as a data test rather than a discussion, because any hit is an error by definition.

Frequently asked questions on IFRS 16 lease modifications

What is a lease modification under IFRS 16?

Appendix A of IFRS 16 defines a lease modification as a change in the scope of a lease, or the consideration for a lease, that was not part of the original terms and conditions of the lease. The examples given in the definition are adding or terminating the right to use one or more underlying assets, and extending or shortening the contractual lease term. The test is whether the original contract already provided for the change. If it did, the change is a reassessment or a variable payment, not a modification.

What is the difference between a lease modification and a lease reassessment under IFRS 16?

A reassessment updates an estimate the original contract already contemplated, such as a change in lease term under IFRS 16.20 or an index-linked rent change under IFRS 16.42(b). A modification is a renegotiation of the contract itself, defined in Appendix A. The distinction is not about which one uses a revised discount rate, because IFRS 16.41 also requires a revised rate on a lease term reassessment. The real difference is that IFRS 16.46(a) can put a gain or loss in profit or loss on a modification that decreases scope, and no reassessment does that.

When is a lease modification accounted for as a separate lease under IFRS 16.44?

IFRS 16.44 requires both conditions to be met. The modification must increase the scope of the lease by adding the right to use one or more underlying assets, and the consideration must increase by an amount commensurate with the stand-alone price for that increase in scope, adjusted for the circumstances of the particular contract. If both hold, the entity recognises a new lease and leaves the original lease untouched. Extending the term of an existing asset can never meet condition (a), because no underlying asset has been added.

Do you use a new discount rate when a lease is modified?

Yes. IFRS 16.45(c) requires the lease liability to be remeasured using a revised discount rate for every modification that is not a separate lease. The revised rate is the interest rate implicit in the lease for the remainder of the lease term if that can be readily determined, and otherwise the lessee's incremental borrowing rate at the effective date of the modification. A separate lease under IFRS 16.44 is measured using its own new rate, and the original lease keeps the rate it had.

How do you account for a partial termination of a lease under IFRS 16?

IFRS 16.46(a) applies. Reduce the carrying amount of the right-of-use asset to reflect the part of the lease that has been terminated, reduce the lease liability for the same proportion, and take the difference to profit or loss. Then apply IFRS 16.45(c) to remeasure the remaining liability at the revised discount rate, with that second adjustment going to the right-of-use asset and not to profit or loss. The order matters, because only the first step touches the income statement.

Where does the gain on a lease modification go in the income statement?

IFRS 16.46(a) requires the gain or loss on a partial or full termination to be recognised in profit or loss but does not specify a line item. IAS 1.85 and, for periods from 1 January 2027, IFRS 18, require classification that faithfully represents the item. A gain arising from a lessee giving up leased space in the course of trading normally sits in operating profit rather than in finance income, because it arises from the derecognition of an operating asset rather than from a financing transaction.

Can a lease modification increase and decrease the scope of a lease at the same time?

Yes, and IFRS 16 does not net the two. Test the increase against IFRS 16.44 first. Anything that is a separate lease is accounted for on its own. Whatever remains is a single modification of the existing lease, and the decrease in scope is dealt with under IFRS 16.46(a) with a gain or loss, before the balance of the remeasurement is adjusted against the right-of-use asset under IFRS 16.46(b).

How does a lessor account for a lease modification under IFRS 16?

It depends on the classification. IFRS 16.79 gives finance lease lessors the same separate lease test as lessees. IFRS 16.80 then requires a non-separate modification to be accounted for as a new lease if the modified lease would have been an operating lease at inception, and otherwise under IFRS 9. IFRS 16.87 gives operating lease lessors a single rule: account for the modification as a new lease from its effective date, carrying forward any prepaid or accrued lease payments.

Is the covid-19 rent concession practical expedient in IFRS 16.46A still available?

No. IFRS 16.46B(b) limits the expedient to concessions where any reduction in lease payments affects only payments originally due on or before 30 June 2022. Every payment inside that window has now fallen due, so no current concession can meet the condition. The paragraphs remain in the standard and matter for comparatives and for understanding a company's accounting history, but a rent concession agreed today is assessed as an ordinary lease modification under IFRS 16.44 to 16.46.

Does an increase in lease payments always mean there has been a lease modification?

No. If the increase comes from a mechanism written into the original contract, such as an index-linked or market rent review, IFRS 16.42(b) treats it as a remeasurement and IFRS 16.43 requires an unchanged discount rate. If the increase comes from a renegotiation, the Appendix A definition is met and IFRS 16.45(c) requires a revised discount rate. The same cash increase therefore produces two different right-of-use asset balances depending only on where the increase came from.

How do lease modifications differ between IFRS 16 and ASC 842?

The separate contract test is close to identical. The differences sit after it. ASC 842 requires the lease classification to be reassessed at the modification date, which IFRS 16 does not, because IFRS 16 has a single lessee model. ASC 842 also makes the basis for reducing the right-of-use asset on a partial termination an explicit accounting policy election between the change in the lease liability and the remaining right of use. IFRS 16 does not offer that election in the text of the standard.

What is the effective date of a lease modification under IFRS 16?

Appendix A defines it as the date when both parties agree to a lease modification. That is the date the accounting is done, not the date the change takes physical effect. A lease amendment signed in December that reduces floor space from the following July is accounted for in December, using the incremental borrowing rate at that December date, even though the space is still occupied at the reporting date.

Does a rent-free period granted by the landlord create a gain?

Not on its own. A negotiated rent-free period is a modification that does not decrease the scope of the lease, so IFRS 16.46(b) applies and the whole remeasurement is a corresponding adjustment to the right-of-use asset. The liability falls and the asset falls with it. The benefit is recognised over the remaining term through lower depreciation and lower interest, not as a credit in the year the concession is agreed.

How do you spot lease modifications in a set of published accounts?

Put the right-of-use asset movement table beside the lease liability movement table and compare the modification line in each. Equal amounts on both sides indicate IFRS 16.46(b) remeasurements with nothing in profit or loss. A larger liability line than asset line indicates a scope decrease, and the difference is the gain under IFRS 16.46(a). No modification line at all means the movements are buried in additions, disposals or a line called Other, and cannot be sized from the accounts.

Key takeaways

  • Classification comes before mechanics. Appendix A asks whether the change was part of the original terms and conditions, and that single question separates the reassessment paragraphs in IFRS 16.39 to 16.43 from the modification paragraphs in IFRS 16.44 to 16.46. The discount rate is not the diagnostic, because IFRS 16.41 revises the rate on a reassessment too.
  • IFRS 16.44 needs both conditions. An underlying asset must be added, and the price of the addition must be commensurate with its stand-alone price. An extension fails condition (a) as a matter of definition, and a discounted addition fails condition (b), pulling the whole original lease into a remeasurement at a new rate.
  • Only IFRS 16.46(a) reaches profit or loss. Everything else is a corresponding adjustment to the right-of-use asset under IFRS 16.46(b), which by construction cannot produce a difference. The gain on a scope decrease exists because the liability falls more slowly than the asset from commencement, not because value has been created.
  • The two steps have to be kept apart, in order, on the right balances. Step one uses pre-modification carrying amounts at the original rate. Step two applies the revised rate under IFRS 16.45(c) and goes nowhere near the income statement. In worked example 3 the rate change moved the liability by GBP 27,782 in the opposite direction to the rent increase, and none of it belonged in the gain.
  • The measurement basis in step one is not specified in IFRS 16.46(a), but it is illustrated. Example 17 applies the proportionate reduction in the remaining right of use to both the right-of-use asset and the lease liability, and the IASB's implementation webcast says to build step one on pre-modification balances at the original rate. ASC 842 instead makes it an explicit policy election, and on one floor of one lease the two bases differed by GBP 3,007. Pick one, write it down, apply it consistently.
  • Lessor accounting is asymmetric, not symmetric. IFRS 16.79 mirrors IFRS 16.44, and then IFRS 16.80 routes finance lessors into IFRS 9 while IFRS 16.87 gives operating lessors a purely prospective answer with no gain or loss at all. The same amendment can move a lessee's operating profit and leave the lessor's untouched.
  • The covid-19 expedient is history. IFRS 16.46B(b) is a fixed date that has passed, and guidance written in 2020 carries a date that was later superseded. The benchmark reform expedient in IFRS 16.105 has no expiry but a real economic equivalence test, and IFRS 16.106 removes it as soon as a commercial change is bundled with it.
  • Disclosure is the weakest link and the standard is the reason. IFRS 16.53 names the sale and leaseback gain and not the modification gain, and requires no movement table. Where the gain is material, the requirement comes from IFRS 16.51, IFRS 16.59 and IAS 1.97, and it has to be argued rather than pointed at.
