Lease contracts often change during their term. A company may add space, surrender part of an office, extend a lease, or see rentals move because of an index already written into the contract. Under Ind AS 116, these events do not all receive the same accounting treatment. The first question is whether the event is a lease modification or a reassessment under the existing lease terms. That distinction affects whether the change becomes a separate lease, how the lease liability is remeasured, which discount rate is used and whether a gain or loss arises.
ICAI notes that Ind AS 116 introduced a single lessee accounting model. For official background and implementation material, readers can refer to ICAI's Ind AS 116 educational-material page, the Educational Material on Indian Accounting Standards 116, Leases, and ICAI's current Compendium of Indian Accounting Standards.
Lease modification and reassessment are different
A lease modification is a change in the scope of a lease, or the consideration for a lease, that was not part of the original terms and conditions. Examples include negotiating additional leased space, giving up part of the leased space, or renegotiating contractual consideration.
A reassessment can arise without negotiating a new right of use. Examples include a changed assessment of an extension or termination option, a changed assessment of a purchase option, a change in amounts expected under a residual value guarantee, or a payment change caused by an index or rate already embedded in the contract. The accounting therefore depends on the trigger, not merely on the fact that future payments changed.
Step 1: Test whether the modification is a separate lease
For a lease modification, Ind AS 116 first asks whether it should be accounted for as a separate lease. Both conditions must be met:
- The modification increases the scope of the lease by adding the right to use one or more underlying assets.
- The consideration increases by an amount commensurate with the stand-alone price for that additional right of use, adjusted where appropriate for the contract's circumstances.
If both conditions are met, the added right of use is accounted for as a separate lease and the accounting for the original lease continues.
Example: adding another office floor
A company leases one office floor and later adds a second floor through an amendment. If the second floor is an additional right of use and its incremental consideration is commensurate with its stand-alone price, the amendment is accounted for as a separate lease. The original lease is not remeasured merely because the new floor was added.
Step 2: If it is not separate, identify whether scope decreased
A modification that is not a separate lease requires the lessee, at the effective date of the modification, to allocate the modified consideration, determine the lease term of the modified lease and remeasure the lease liability using a revised discount rate. The revised rate is the interest rate implicit in the lease for the remainder of the term if it can be readily determined; otherwise the lessee uses its incremental borrowing rate at the effective date of the modification.
When the modification decreases scope
If the company gives up part of the leased asset or otherwise reduces the lease scope, the carrying amount of the right-of-use asset is reduced to reflect the partial or full termination. The related portion of the lease liability is also removed, and the resulting difference is recognised as a gain or loss. The liability for the continuing lease is then remeasured using the revised discount rate.
Example: surrendering 30% of an office
Suppose a company occupies 10,000 square feet and agrees with the lessor to surrender 3,000 square feet for the remaining term. The finance team should account for the partial termination by reducing the right-of-use asset and lease liability for the rights given up and recognising the resulting gain or loss. It should then remeasure the liability for the continuing 7,000 square feet using the revised discount rate at the modification date.
When scope is not reduced
If a non-separate modification changes consideration or other terms without reducing scope, the remeasurement of the lease liability is generally matched by an adjustment to the right-of-use asset, subject to the detailed requirements of Ind AS 116.
Step 3: Distinguish index-linked changes from modifications
Assume rent changes because the original contract specifies escalation by a consumer price index. No new contractual right has necessarily been negotiated. This is generally a remeasurement under the existing lease terms rather than a lease modification. Ind AS 116 generally uses an unchanged discount rate for remeasurement arising from changes in amounts expected under a residual value guarantee or changes in future lease payments caused by an index or rate. If the change in lease payments results from a change in floating interest rates, the discount rate is revised to reflect the interest-rate change.
By comparison, a reassessment of the lease term or of whether the lessee is reasonably certain to exercise a purchase option requires remeasurement using a revised discount rate. Identifying the precise trigger is therefore essential before updating the lease schedule.
Practical accounting workflow
- Collect evidence. Obtain the original lease, amendments, option notices, index-reset notices, approvals and updated payment schedules.
- Identify the trigger. Decide whether scope or consideration was renegotiated, or an existing contractual mechanism or option assessment changed.
- Apply the separate-lease test. For an added asset or right of use, test both the additional-scope and stand-alone-price conditions.
- Identify any scope decrease. If rights were surrendered, quantify the portion of the right-of-use asset and lease liability related to the termination.
- Select the correct discount rate. Do not automatically reuse the original rate; the required rate depends on the type of change.
- Rebuild the lease schedule. Recalculate the liability from the effective date using the appropriate cash flows, remaining term and discount rate.
- Post the adjustment. Separate leases are recorded separately; scope decreases can create a gain or loss; other remeasurements generally adjust the right-of-use asset.
- Update support. Revise depreciation where needed and retain the contract analysis, calculations and discount-rate support for audit review.
Common mistakes
- Treating every rent change as a lease modification.
- Calling an amendment a separate lease without confirming that an additional right to use an underlying asset was added.
- Using the original discount rate for every remeasurement.
- Ignoring the gain-or-loss effect when a modification reduces lease scope.
- Updating the liability but not the right-of-use asset, depreciation schedule or supporting documentation.
Practical takeaway
For an Ind AS 116 contract change, start with the contract rather than the spreadsheet. Determine whether the event changes contractual scope or consideration outside the original terms, or instead remeasures an existing contractual feature. If it is a modification, apply the separate-lease test; if it is not separate, determine whether scope decreased and remeasure as required. If it is a reassessment, identify the specific trigger because discount-rate treatment can differ. A short written decision memo linking the facts to these steps can prevent errors in lease schedules, depreciation and audit support.
