AS 26 Intangible Assets: Impairment, Retirement, Disposal and Disclosures
Updated 4 October 2026 · Fact-checked
AS 26 says an intangible asset is derecognised on disposal or when no future benefits are expected. Gain or loss equals net disposal proceeds minus carrying amount, and goes to the Statement of Profit and Loss. Impairment is tested under AS 28. AS 26 also requires class-wise disclosures.
Understand Impairment, Retirement, Disposal and Disclosures
An intangible asset has a life that ends. It ends when you sell it, or when you expect no more economic benefit from using it or selling it. At that point you remove it from the books. This is called derecognition.
When you remove it, you compare what you receive with what is on the books. The carrying amount is cost less accumulated amortisation less accumulated impairment losses. The difference is a gain or a loss. It is shown in the Statement of Profit and Loss. AS 26 states that a gain on disposal should not be classified as revenue. AS 9 is the revenue standard.
Impairment is a separate question. An asset is impaired when its carrying amount is more than its recoverable amount. AS 26 does not give the method. It sends you to AS 28. Recoverable amount is the higher of net selling price and value in use. The loss is the excess of carrying amount over recoverable amount.
AS 26 also asks for disclosure. For each class of intangibles, separating internally generated from others, you give useful lives or amortisation rates, the amortisation method, gross carrying amount, accumulated amortisation, and a reconciliation of opening and closing carrying amounts. You also disclose research and development expenditure recognised as an expense in the period.
Two more points help in the exam. An intangible asset retired from active use and held for disposal is carried at its carrying amount at the date when it is retired from active use, and AS 28 impairment testing applies to it. And on transition, where AS 26 requires its recognition criteria to be met, items previously recognised that do not qualify are adjusted against opening revenue reserves. Read the facts given in the question and apply them.
Key rules to remember
- Gain or loss on disposal
- Gain or (loss) = Net disposal proceeds − Carrying amount
- Net disposal proceeds are sale price less selling costs. Show the result in the Statement of Profit and Loss.
- Carrying amount
- Carrying amount = Cost − Accumulated amortisation − Accumulated impairment losses
- Amortise up to the date of disposal before you work out the gain or loss.
- Recoverable amount (AS 28)
- Recoverable amount = Higher of (Net selling price, Value in use)
- Net selling price is selling price less costs of disposal. Value in use is the present value of estimated future cash flows.
- Impairment loss (AS 28)
- Impairment loss = Carrying amount − Recoverable amount, if carrying amount is higher
- If recoverable amount is higher, there is no impairment loss.
- Derecognition trigger
- Derecognise on disposal OR when no future economic benefits are expected from use or disposal
- Both triggers lead to removal from the books.
- Amortisation after impairment (straight-line method)
- Revised annual amortisation = (Revised carrying amount − Residual value) ÷ Remaining useful life
- This applies to the straight-line method. The depreciable amount is the revised carrying amount less any residual value, which is normally assumed to be zero under AS 26. If another method is used, it follows the pattern of benefits.
How to solve Impairment, Retirement, Disposal and Disclosures questions
Use the same order for any question on impairment, disposal or disclosure of an intangible asset.
- 1Read the question and mark what is asked: gain or loss, impairment loss, journal entry or disclosure.
- 2List cost, date of acquisition, useful life and amortisation method.
- 3Compute amortisation up to the date of disposal or the balance sheet date, whichever is relevant.
- 4Find the carrying amount: cost less accumulated amortisation less any impairment already booked.
- 5For impairment, find net selling price and value in use. Take the higher as recoverable amount. Compare with carrying amount.
- 6For disposal, find net proceeds after selling costs. Subtract the carrying amount to get the gain or loss.
- 7Write the journal entry or the extract of the Statement of Profit and Loss.
- 8If disclosures are asked, list them class-wise and add the reconciliation of carrying amounts.
Quickest way: Carrying amount first, then compare
When to use it: Use this for time-pressed numerical questions and MCQs on gain, loss or impairment.
- Compute the carrying amount first. Most errors start here.
- For MCQs, note that the answer is always proceeds minus carrying amount. Eliminate options that use cost instead.
- For impairment MCQs, pick the higher of net selling price and value in use. Then subtract from carrying amount. Eliminate options that use the lower figure.
- In written answers, use three lines: working of amortisation, carrying amount, gain or loss. Each line earns step marks.
- State the treatment in one sentence, such as 'Loss is charged to the Statement of Profit and Loss'.
Common mistakes in Impairment, Retirement, Disposal and Disclosures
Using original cost instead of carrying amount to compute gain or loss.
Students forget to deduct accumulated amortisation up to the disposal date.
Fix: Always write the carrying amount working first, including amortisation for the part of the year up to disposal.
Taking the lower of net selling price and value in use as recoverable amount.
Prudence is confused with the AS 28 definition.
Fix: Recoverable amount is the higher of the two. Repeat this until it is automatic.
Ignoring selling costs when finding net proceeds.
Students read only the sale price.
Fix: Deduct costs of disposal from the sale price before comparing with the carrying amount.
Showing gain on disposal as revenue.
The gain looks like income.
Fix: Show it as a gain in the Statement of Profit and Loss. AS 26 states that the gain should not be classified as revenue. AS 9 is the revenue standard.
Not changing amortisation after an impairment loss.
Students keep the old charge.
Fix: Spread the revised carrying amount, less any residual value, over the remaining useful life. The simple division applies to the straight-line method.
Giving incomplete disclosures, such as skipping the reconciliation or the research and development expense.
Students remember only useful life and method.
Fix: Use a checklist: class, internal or other, life or rate, method, gross and accumulated amounts, reconciliation, R&D expense.
Worked examples
Example 1
A company bought a patent on 1 April 2023 for ₹10,00,000. Useful life is 10 years, straight-line amortisation, no residual value. On 30 September 2026 it sold the patent for ₹7,50,000, incurring selling costs of ₹10,000. Find the gain or loss on disposal.
Show the solution
- Annual amortisation = ₹10,00,000 ÷ 10 = ₹1,00,000.
- Period from 1 April 2023 to 30 September 2026 = 3 years 6 months = 3.5 years.
- Accumulated amortisation = ₹1,00,000 × 3.5 = ₹3,50,000.
- Carrying amount = ₹10,00,000 − ₹3,50,000 = ₹6,50,000.
- Net disposal proceeds = ₹7,50,000 − ₹10,000 = ₹7,40,000.
- Gain = ₹7,40,000 − ₹6,50,000 = ₹90,000.
Answer: Gain on disposal is ₹90,000, credited to the Statement of Profit and Loss.
Example 2
A company owns a trademark with a carrying amount of ₹12,00,000 at the balance sheet date. Its remaining useful life is 4 years. Net selling price is ₹8,00,000 and value in use is ₹9,00,000. Compute the impairment loss and the revised annual amortisation, assuming straight-line and no residual value.
Show the solution
- Recoverable amount = higher of ₹8,00,000 and ₹9,00,000 = ₹9,00,000.
- Carrying amount ₹12,00,000 is more than recoverable amount, so the asset is impaired.
- Impairment loss = ₹12,00,000 − ₹9,00,000 = ₹3,00,000.
- Charge the loss to the Statement of Profit and Loss.
- Revised carrying amount = ₹9,00,000.
- Revised annual amortisation = ₹9,00,000 ÷ 4 = ₹2,25,000.
Answer: Impairment loss is ₹3,00,000. Revised amortisation is ₹2,25,000 a year.
Exam tips
- In numerical questions, always show the carrying amount working. It earns step marks even if the final figure is wrong.
- Check dates carefully. Part-year amortisation up to the disposal date is a favourite trap.
- For disclosure questions, write a short checklist in order: class, life or rate, method, gross and accumulated amounts, reconciliation, R&D expense.
- In MCQs on impairment, compute the recoverable amount as the higher figure before looking at the options.
- Link AS 26 with AS 28 in written answers. Name AS 28 when you explain how impairment is measured.

Impairment, Retirement, Disposal and Disclosures: frequently asked questions
How do I calculate gain or loss on disposal of an intangible asset under AS 26?
Subtract the carrying amount from the net disposal proceeds. Carrying amount is cost less accumulated amortisation and impairment. A positive result is a gain and a negative result is a loss, both shown in the Statement of Profit and Loss.
Which standard governs impairment of intangible assets?
AS 28 Impairment of Assets sets the method. AS 26 requires you to apply it. You compare carrying amount with recoverable amount, which is the higher of net selling price and value in use.
When is an intangible asset derecognised?
It is derecognised on disposal, or when no future economic benefits are expected from its use or disposal. Its carrying amount is then removed and any difference is recognised in the Statement of Profit and Loss.
What disclosures does AS 26 require?
For each class of intangibles you disclose useful lives or amortisation rates, the method, gross carrying amount, accumulated amortisation and a reconciliation of opening and closing carrying amounts. You also disclose the research and development expense recognised in the period.
