Recognition does not settle the useful-life decision
An intangible asset already recognised under Ind AS 38 still needs a separate assessment of whether its useful life is finite or indefinite. A finite-life asset is amortised over its useful life; an indefinite-life asset is not amortised but requires the applicable impairment testing. A long commercial history does not make a recognised brand indefinite automatically, and a legal right lasting many years does not guarantee equally long economic use.
This guide applies to entities reporting under Ind AS and to recognised intangible assets within Ind AS 38, particularly paragraphs 88–110 and 118–122. It uses the ICAI official Ind AS compendium standard text, checked on 23 October 2026. It addresses useful-life and subsequent-amortisation judgements rather than a Schedule III note format or the initial capitalisation of software development. The examples assume recognition and initial measurement are already correct; cost-model accounting applies, and tax effects are outside their scope.
Contractual and economic limits must both be assessed
Paragraphs 94–95 limit the useful life of an asset arising from contractual or legal rights to that rights period, while economic factors may justify a shorter period. Renewal periods are included only with supporting evidence of renewal without significant cost. A management intention to renew is weaker than evidence concerning renewal conditions, past practice, costs and continued economic benefits.
A reacquired right recognised in a business combination has a specific rule: its useful life is the remaining contractual period of the original grant, without renewal periods. Do not import a wider market-participant or operational renewal horizon into that amortisation calculation merely because the group expects the relationship to continue.
Available for use is the start point
Under paragraph 97, amortisation starts when the asset is in the location and condition necessary to operate as management intends. Invoice date, payment date, ceremonial launch and first revenue are not substitutes. A delay in marketing after the asset becomes ready does not automatically postpone amortisation. Finite-life assets generally continue to be amortised while idle unless the applicable cessation rule is met; output-based methods can produce a different charge where appropriate.
Select a method reflecting consumption of economic benefits; where that pattern cannot be determined reliably, use straight-line. Do not choose a revenue-based charge merely because sales forecasts are convenient. Paragraphs 98A–98C contain a rebuttable presumption against revenue-based amortisation and limited exceptions; they require their own fact-based assessment.
Residual value is normally zero
Paragraph 100 presumes zero residual value unless the specified third-party purchase commitment or active-market conditions are met. A general expectation of resale, an internal valuation model or the asset’s original purchase price does not itself satisfy those exceptions. Review residual value at least at each financial year-end. If it equals or exceeds carrying amount, the charge can be zero until that condition ceases, but the assessment must be evidenced.
Indefinite does not mean permanent
An indefinite useful life means there is no foreseeable limit to the period of expected net cash inflows after considering relevant factors; it does not mean infinite life or freedom from review. Paragraphs 107–108 require no amortisation and impairment testing annually and whenever impairment indications exist, in accordance with Ind AS 36. Use the appropriate asset or cash-generating-unit level; a stand-alone valuation is not automatically available for every intangible.
Paragraphs 109–110 require reassessment each period of the indefinite-life conclusion. Changing to a finite life is an accounting-estimate change under Ind AS 8 and is itself an impairment indicator. Test the carrying amount against the relevant recoverable amount and amortise the resulting amount prospectively over the newly assessed remaining life. Do not retroactively manufacture amortisation for earlier periods solely because the estimate has changed.
For finite-life assets, paragraph 104 requires review of amortisation period and method at least at each year-end. Revise estimates prospectively where justified; distinguish a new estimate from correcting an error in the facts or standard originally applied. The disclosure file should explain material changes, finite/indefinite classification, methods, useful lives or rates and the basis supporting a material indefinite-life assessment.
Worked illustrations
These illustrations use fictional facts and expressly stated assumptions. Amounts are Indian rupees unless a different currency or unit is specified. They are independent examples, not findings about any actual client.
Illustrative example 1: Legal term is shorter than the economic forecast
A recognised licence costs ₹24,00,000 and is available for use on 1 October 2026. Economic use is expected for eight years, but the enforceable right expires after five years and no qualifying renewal evidence exists. Useful life = min(8,5) = five years. With zero residual value, straight-line annual amortisation = ₹4,80,000. Using an expressly assumed month-based convention, six months to 31 March 2027 give ₹2,40,000 and closing carrying amount ₹21,60,000.
Illustrative example 2: A supported renewal period can change the horizon
A recognised right costs ₹18,00,000, with three contractual years remaining and evidence supporting one further three-year renewal without significant cost. Economic benefits are expected for six years; no reacquired-right exception applies. Supported life is six years, not automatically just the first three. Zero-residual straight-line amortisation is ₹3,00,000 annually; after one full year carrying amount is ₹15,00,000. Reassess if the renewal evidence changes.
Illustrative example 3: Reacquired right excludes renewals
A business combination recognises a reacquired distribution right at ₹12,00,000. The original grant has two years remaining; the group expects another four years through renewal. Paragraph 94’s reacquired-right rule uses the remaining two contractual years, not six. At zero residual value, annual straight-line amortisation is ₹6,00,000. A six-year calculation would charge ₹2,00,000 annually and understate the first full-year charge by ₹4,00,000.
Illustrative example 4: A qualifying third-party commitment supports residual value
A finite-life intangible costs ₹10,00,000 and has a five-year useful life. Assume a valid third-party commitment to purchase it for ₹1,00,000 at life-end satisfies paragraph 100, with no contrary facts. Depreciable amount = ₹10,00,000 − ₹1,00,000 = ₹9,00,000; annual straight-line charge = ₹1,80,000. After two full years, carrying amount = ₹10,00,000 − ₹3,60,000 = ₹6,40,000. Without a qualifying residual basis, the zero-residual calculation would differ.
Illustrative example 5: Revise the remaining finite life prospectively
A ₹20,00,000 asset originally had a ten-year life and zero residual value. Two full years of straight-line amortisation at ₹2,00,000 leave ₹16,00,000. At the next year’s start, new evidence supports only four more years of use. Assuming no impairment, revised annual charge = ₹16,00,000/4 = ₹4,00,000; carrying amount after that year is ₹12,00,000. Do not recalculate the first two years as if the new estimate had always existed.
Illustrative example 6: Indefinite life does not remove impairment
A correctly recognised indefinite-life acquired brand has a ₹30,00,000 carrying amount. Assume it can be tested individually under Ind AS 36 and its properly determined recoverable amount is ₹27,00,000. Amortisation is nil, but impairment is ₹30,00,000 − ₹27,00,000 = ₹3,00,000, leaving ₹27,00,000. A nil amortisation entry is not evidence that the closing carrying value remains ₹30,00,000.
Illustrative example 7: Indefinite becomes finite with an impairment indicator
At the start of a reporting year, a recognised asset’s indefinite-life assessment changes to a five-year remaining finite life. Carrying amount before the review is ₹15,00,000; assume the appropriate Ind AS 36 test gives a ₹12,00,000 recoverable amount. Impairment is ₹3,00,000. With zero residual value, subsequent full-year straight-line amortisation is ₹12,00,000/5 = ₹2,40,000, leaving ₹9,60,000. Amortising the pre-impairment ₹15,00,000 would incorrectly charge ₹3,00,000 for that year.

Sixteen practitioner FAQs
1. Does this guide apply automatically to AS 26 reporters?
No. It addresses Ind AS 38. Establish the applicable reporting framework before applying its finite/indefinite-life model.
2. Does initial recognition prove an indefinite useful life?
No. Recognition and useful-life classification are separate judgements requiring different evidence.
3. Can the economic forecast exceed a non-renewable legal term?
A longer forecast cannot extend the entity’s enforceable control period. Paragraphs 94–95 require the legal and economic limits to be considered.
4. Is an intention to renew enough?
No. Include renewal periods only where the standard’s supporting-evidence and cost conditions are met.
5. Do reacquired rights include expected renewals?
Paragraph 94 excludes renewal periods for a reacquired right recognised in a business combination; use the remaining original contractual term.
6. Does amortisation begin on payment?
Not necessarily. The start point is when the asset is available for use in the location and condition needed for management’s intended operation.
7. Can a postponed sales launch defer the charge?
Not merely because revenue starts later if the asset is already available for use.
8. Is straight-line always compulsory?
No. Use a systematic method reflecting benefit consumption; straight-line applies where that pattern cannot be determined reliably.
9. Are sales forecasts sufficient for revenue-based amortisation?
No. Paragraphs 98A–98C presume such a method inappropriate unless the specified limited circumstances justify it.
10. Can an expected resale amount always be residual value?
No. Paragraph 100 sets specific third-party-commitment or active-market conditions; otherwise residual value is assumed zero.
11. How often are finite-life estimates reviewed?
At least at each financial year-end for the period and method, with residual-value review also required.
12. Does indefinite mean the asset lasts forever?
No. It means no foreseeable limit under the standard’s assessment, not an infinite economic life.
13. Does an indefinite asset escape annual impairment testing?
No. Annual testing and testing on impairment indications remain required under the applicable Ind AS 36 framework.
14. Is every brand tested as a stand-alone asset?
No. Determine whether testing must be at asset or cash-generating-unit level under Ind AS 36.
15. What happens when indefinite life becomes finite?
Treat the reassessment as an estimate change, assess the resulting impairment indication, and amortise the appropriate carrying amount prospectively over the remaining finite life.
16. Should earlier amortisation be restated for a new estimate?
Not solely because the estimate changes. Distinguish a prospective estimate change from an actual prior-period error under Ind AS 8.
