Amortise with the related transfer pattern

Ind AS 115 paragraph 99 requires an asset recognised under paragraph 91 or 95 to be amortised systematically in line with transfer to the customer of the goods or services to which it relates. Paragraph 100 requires an update for a significant change in expected timing of that transfer, accounted for as a change in estimate under Ind AS 8. The invoice schedule, receipt of cash or a default three-year write-off is not automatically the correct pattern.

Read the applicable text: MCA: Ind AS 115, paragraphs 91, 95 and 99–100; separate impairment requirements from paragraph 101.

Establish the asset and its relationship first

This guide assumes recognition under the relevant contract-cost criteria has already been justified. If the paragraph 94 practical expedient to expense eligible incremental acquisition costs with an amortisation period of one year or less is used, there is no capitalised asset for those costs to amortise under this working. It does not capitalise ordinary expenses merely by spreading them. Identify the cost cohort, recognition date, related goods or services and any supported specific anticipated contract. Costs covered by another standard require their own analysis. A recoverability conclusion does not by itself establish which transfers the asset relates to.

Choose a systematic basis supported by actual performance

For uniform services, a time basis may be appropriate on the established facts. For a supported unit-related cohort, the transfer pattern may instead follow units. Explain how the method represents transfer of the related goods or services, including what marks its commencement. Do not select an accelerated or slower pattern simply to reach a desired profit. An invoice paid in full can coexist with an unamortised cost asset if the relevant transfers continue.

Update estimates without rewriting valid history

Compare current expectations with the transfer schedule used before. When a significant timing change is genuinely a new estimate, update the remaining amortisation on that supported basis. Do not retrospectively rewrite earlier expense solely because forecasts changed. Equally, an earlier mistake in recognition or use of available information should not be disguised as an estimate change; apply the appropriate Ind AS 8 analysis separately.

Keep amortisation separate from impairment

Paragraphs 101 onward address impairment and related requirements. A revised amortisation horizon does not remove the need for the applicable recoverability review. Record amortisation and impairment as distinct movements so that one cannot conceal the other. This article focuses on the transfer pattern and estimate-change roll-forward, rather than reproducing the separate impairment and reversal computation.

Close by cohort, not only in aggregate

Maintain opening carrying amount, qualifying additions, current amortisation, other supported movements and closing balance. Link the schedule to the general ledger and related transfer evidence. Preserve the approval and effective date of each estimate update. Check that no cohort is amortised twice through both a manual journal and an automated schedule. The illustrations use fictional, independently justified assets and transfer assumptions; they do not establish capitalisation merely from a payment description.

Six worked illustrations

All facts and amounts are fictional. Calculations illustrate the stated assumptions, not a predetermined legal outcome.

Illustrative example 1: Uniform service pattern

Assume a qualifying ₹1,20,000 asset relates to 24 months of evenly transferred services, beginning at the start of the period. Monthly amortisation is ₹5,000. Six months give ₹30,000 expense and ₹90,000 remaining, before any other applicable movements.

Illustrative example 2: Supported unit basis

A qualifying ₹2,00,000 cohort relates to transfer of 10,000 units on a supported proportional basis. Transfer of 2,500 units produces ₹50,000 amortisation, leaving ₹1,50,000. Using 25% here requires the stated relationship, not merely a convenient percentage of sales invoices.

Illustrative example 3: New estimate shortens the remaining pattern

An asset originally ₹1,20,000 has correctly incurred ₹30,000 amortisation, leaving ₹90,000. New supported information changes remaining uniform service transfer to 9 months. Prospective monthly amortisation is ₹10,000; the previously valid ₹30,000 is not recalculated solely because of this new estimate.

Illustrative example 4: New estimate extends the remaining pattern

Assume ₹60,000 carrying amount remains and a supported new estimate extends uniform remaining transfers to 15 months. Prospective monthly amortisation becomes ₹4,000. The extension needs evidence and does not itself resolve impairment or prove the cost relates to every future renewal.

Illustrative example 5: Separate cohorts and start dates

One qualifying cohort of ₹1,20,000 is amortised over 12 uniform months and has 3 months' transfers in the reporting period: ₹30,000. A second ₹60,000 cohort over 12 uniform months has 1 month: ₹5,000. Combined amortisation is ₹35,000, leaving ₹1,45,000 of the ₹1,80,000 original total, before other movements.

Illustrative example 6: Roll-forward without duplicate expense

Opening asset ₹80,000 plus qualifying additions ₹40,000 less correctly calculated amortisation ₹30,000 gives ₹90,000 closing balance, assuming no other movements. A duplicate manual ₹30,000 journal would reduce it incorrectly to ₹60,000. Reconcile the posting source before booking another expense.

Sixteen practitioner FAQs

1. Does paragraph 99 apply to every prepaid expense?

No. It concerns assets recognised under paragraph 91 or 95; other standards and recognition tests remain relevant.

2. Can an expense be capitalised just to smooth profit?

No. Recognition must be justified independently.

3. What drives the amortisation basis?

Transfer of the goods or services to which the asset relates.

4. Is straight-line amortisation always required?

No. Use a systematic basis consistent with the actual related transfer pattern.

5. Can a time basis be appropriate?

Yes, where supported by uniform related services and the actual facts.

6. Can a unit basis be appropriate?

Yes, where the asset's relationship to those unit transfers supports it.

7. Does customer payment determine expense timing automatically?

No. Cash timing and the relevant transfer pattern are different matters.

8. Does an invoice date prove commencement?

Not necessarily. Establish the relevant transfer-start event.

9. Can an asset relate to an anticipated contract?

Paragraph 99 refers to a specific anticipated contract as described in paragraph 95(a); support the actual relationship.

10. What does paragraph 100 require when expected timing changes significantly?

Update amortisation and treat that change as an accounting-estimate change under Ind AS 8.

11. Should a genuine new estimate automatically restate prior valid expense?

No. Distinguish a new estimate from an earlier error.

12. Can a longer forecast remove the need for impairment review?

No. Keep the applicable impairment assessment separate.

13. Should impairment be labelled amortisation?

No. Maintain distinct movements and supporting calculations.

14. Why separate cohorts?

Different recognition and transfer-start dates can produce different period expense.

15. Can a manual journal duplicate an automated schedule?

Yes. Reconcile both posting sources before adding an adjustment.

16. What should the reviewer reproduce?

Recognition support, related transfers, method, timing, estimate updates and the closing carrying amount.
