101. Shortly after the reporting date, but before the financial statements are authorised for issue, an entity discovers a material mistake that was made not in the immediately preceding comparative period, but in a period THREE YEARS earlier, which has been carried forward (uncorrected) in every set of financial statements issued since. How does the timing of this discovery (before authorisation for issue of the CURRENT period's financial statements) affect the correction required, compared with an ordinary current-period adjusting event under IAS 10?

A) Because the error is discovered before the current period's financial statements are authorised for issue, it is treated as an IAS 10 adjusting event affecting only the current period's figures, with no need to restate any of the genuinely affected historical comparative periods
B) The discovery timing (before authorisation for issue) determines only when the correction is made and disclosed, not which periods are restated; since the error genuinely originated three years earlier and has persisted since, IAS 8 still requires correction by restating the earliest practicable prior period presented (adjusting the opening balance of the earliest period's retained earnings, and each subsequent comparative period individually, as far as practicable) rather than treating it as a current-period-only adjusting event simply because of when it happens to have been discovered
C) Only the current year's figures are adjusted, with all prior years' figures left exactly as originally reported, regardless of when the error actually originated
D) The error is simply ignored entirely, since it originated too long ago to be practicably corrected under any circumstances

Correct: B complex IAS 8 / IAS 10 - discovery timing before authorisation for issue does not convert a multi-year-old error into a current-period-only adjusting event

IAS 10's adjusting/non-adjusting event distinction concerns evidence about conditions existing at the reporting date for the CURRENT period being reported on. It is a separate question from IAS 8's requirement to correct a material prior period error, which is driven by which period the error actually originated in and affected, not by when the error happens to be discovered. Regardless of the convenient timing of discovery (before the current financial statements are authorised for issue), an error that genuinely originated three years earlier is corrected under IAS 8 by restating as far back as practicable, adjusting the earliest presented period's opening retained earnings and each intervening comparative period, rather than being folded into the current period alone as if it were an ordinary adjusting event.

102. An entity discovers that a compound financial instrument (a convertible loan note) issued several years ago had its liability and equity components originally split using an incorrect discount rate at initial recognition, a genuine calculation error rather than a change in estimate, resulting in the liability component being understated and the equity component correspondingly overstated ever since issuance. How should this original split error be corrected upon discovery?

A) As a prior period error under IAS 8, requiring retrospective recalculation of the correct liability and equity components using the correct discount rate at the original issuance date, restatement of all subsequent periods' amortised cost, effective interest, and finance cost figures for the liability component, and a corresponding correction to the equity component and retained earnings/opening balances for the affected periods
B) Only the current period's finance cost is adjusted, with the original split between the liability and equity components left permanently unchanged
C) The error can never be corrected once the original conversion option has lapsed or been exercised, regardless of when it is discovered
D) It is treated as a change in accounting estimate, applied prospectively only from the date of discovery, with no restatement of prior periods' finance costs

Correct: A complex IAS 8 / IAS 32 - original compound instrument split discount rate error corrected retrospectively

An error in the original discount rate used to split a compound instrument's liability and equity components at initial recognition is a genuine calculation mistake, not a change in estimate, and is corrected as a prior period error under IAS 8. This requires recalculating the correct liability and equity components using the correct discount rate as at the original issuance date, restating all subsequent periods' amortised cost, effective interest expense, and finance cost figures for the corrected liability component, and making a corresponding correction to the equity component and to opening retained earnings and other affected balances for the periods concerned.

103. An entity has, for several years, capitalised borrowing costs on a qualifying asset under construction using its general borrowings pool weighted average rate, when in fact a specific loan taken out directly for that construction project (at a materially different, lower interest rate) was actually available and should have been used to determine the borrowing costs eligible for capitalisation under IAS 23. This is a genuine mistake in applying IAS 23's own hierarchy (specific borrowings first, general pool only for expenditure not covered by specific borrowings), discovered only now. How should this be corrected?

A) No correction is required at all, since general pool rates and specific borrowing rates are considered interchangeable acceptable alternatives under IAS 23
B) As a prior period error under IAS 8, since the mistake was in correctly applying IAS 23's own specific-borrowings-first hierarchy to facts (the existence and applicability of the specific loan) that were fully available and known at the time, requiring retrospective recalculation of the amount of borrowing costs that should have been capitalised using the correct (specific loan) rate, and restatement of the asset's carrying amount, accumulated depreciation, and related deferred tax for all affected periods
C) As a change in accounting estimate, applied prospectively from the date of discovery, since the borrowing cost capitalisation rate is inherently an estimate
D) The correction is made only to the current period's finance cost, leaving the asset's historical carrying amount and accumulated depreciation permanently unchanged

Correct: B complex IAS 8 / IAS 23 - specific-borrowings-first hierarchy misapplication corrected retrospectively

IAS 23 establishes a specific hierarchy: borrowing costs directly attributable to a qualifying asset are determined by reference to specific borrowings where they exist, with the general borrowings pool used only for expenditure not covered by a specific borrowing. Using the general pool rate when a specific, directly attributable borrowing was actually available is a mistake in applying that hierarchy to facts that were fully known and available at the time, constituting a prior period error under IAS 8, requiring retrospective recalculation of the correct capitalised borrowing costs and restatement of the asset's carrying amount, accumulated depreciation, and related deferred tax for all periods affected by the original mistake.

104. An entity had, in a prior period, publicly disclosed a non-GAAP earnings forecast (a voluntary market announcement of expected future profits, entirely outside the financial statements themselves) that later turns out to have been significantly wrong once actual results were reported. Does this incorrect forecast trigger any correction obligation under IAS 8?

A) No; IAS 8's error correction and restatement requirements apply specifically to material misstatements or omissions WITHIN the financial statements themselves (for particular periods presented); a voluntary, forward-looking, non-GAAP earnings forecast made outside the financial statements is not itself a financial statement figure for a past reporting period, so its later inaccuracy, however significant, does not fall within IAS 8's scope of financial statement error correction, though it may raise separate market disclosure or investor relations considerations
B) The forecast must be treated as a contingent liability and disclosed in the notes to the financial statements for every period until it is superseded
C) The actual reported results must be adjusted retrospectively to match whatever the original forecast stated, since the forecast was issued first
D) Yes, any materially inaccurate forward-looking forecast, whether or not it forms part of the financial statements, must be corrected as a prior period error under IAS 8

Correct: A complex IAS 8 - scope boundary excluding voluntary non-GAAP forecasts made outside the financial statements from error correction requirements

IAS 8 governs the correction of material errors within the financial statements themselves, relating to amounts and disclosures for particular past reporting periods. A voluntary, forward-looking, non-GAAP earnings forecast is fundamentally different in nature: it is not a financial statement figure reporting on a past period at all, but a prediction about the future made outside the financial statements. Its later inaccuracy, however significant, therefore does not fall within IAS 8's scope of financial statement error correction, notwithstanding that it may raise entirely separate considerations under securities law, market disclosure obligations, or investor relations practice.

105. An investment management firm prepares combined financial statements covering two separate legal fund entities under its common management, for the convenience of investors who invest across both funds. A material error is discovered within these combined financial statements, but on closer investigation, the error actually originated entirely within one of the two funds' own individual records and never affected the other fund at all. How should the correction of this error be scoped?

A) The correction is applied proportionately across both funds equally, regardless of which fund's own records the error actually originated in, since the combined financial statements present the two funds together
B) The correction should be scoped to the specific fund whose own individual records actually contained the error, restating that fund's own figures within the combined presentation (and its own separate financial statements, if any are also issued), while the other fund's figures, never having contained the error, are not restated at all, since IAS 8 correction is driven by which entity's own records the error genuinely originated in and affected, not by the fact that a combined presentation happens to bring the two together
C) Neither fund's figures are restated at all, since a combined financial statement error can never be attributed back to one specific underlying fund
D) The combined financial statements must be permanently discontinued once any error is discovered affecting only one of the two underlying funds

Correct: B complex IAS 8 - error correction scoped to the specific reporting entity whose own records actually contained the error within a combined presentation

Correcting a prior period error is fundamentally about restating the figures of the specific reporting entity (or entities) whose own records actually contained the error and were genuinely misstated. Where a combined presentation brings together two otherwise separate legal entities purely for investor convenience, an error properly traced to one fund's own individual records is corrected only in that fund's own figures (as reflected within the combined presentation and any separate financial statements), while the other fund's figures, never having been affected, require no restatement at all, simply because the two happen to be presented together.

106. An entity's defined benefit pension plan valuation has, for several consecutive years, continued to use a specific mortality table that was already known, publicly superseded, and acknowledged as outdated by the actuarial profession at the time each of those valuations was actually performed, rather than the updated mortality table that was already available and should have been used. How should this be distinguished from an ordinary annual update of actuarial assumptions to reflect newly published data, and how is it corrected?

A) The correction is made only by adjusting the current period's pension expense, with no restatement of any prior period's reported pension figures
B) The use of any mortality table, however outdated, can never be treated as an error, since mortality assumptions are always inherently uncertain estimates
C) Both situations are treated identically, as a change in accounting estimate applied prospectively, since actuarial assumptions are inherently estimates
D) Continuing to use a mortality table that was already known and acknowledged to be outdated at the time each valuation was performed, when an updated table was already available, is a mistake in applying information that already existed and was available, constituting a prior period error under IAS 8 requiring retrospective restatement of the affected periods' pension figures; this is distinguished from an ordinary annual update reflecting genuinely new mortality data only just published, which is a change in accounting estimate applied prospectively

Correct: D complex IAS 8 / IAS 19 - outdated actuarial assumption already known at the time corrected retrospectively, distinguished from an ordinary prospective assumption update

The distinction between an error and a change in estimate turns on whether the mistake reflects a failure to use information that was already available and known at the time, or reflects genuinely new information that has since emerged. Continuing to use a mortality table already publicly acknowledged as outdated, when an updated table was already available at the time each valuation was performed, is a failure to use available information, constituting a prior period error requiring retrospective restatement, in contrast to an ordinary annual assumption update reflecting genuinely new mortality data that has only just become available, which is a routine change in accounting estimate applied prospectively.

107. An entity voluntarily discloses, alongside its financial statements, a non-financial sustainability metric (for example, an estimate of its total greenhouse gas emissions for the year), which is not itself part of the audited primary financial statements or their notes. This metric is later found to have been calculated incorrectly for a prior period. Does IAS 8's mandatory restatement requirement apply to correcting this non-financial metric?

A) Yes, IAS 8's restatement requirements apply identically to any information published by the entity, whether financial or non-financial, and regardless of whether it forms part of the financial statements themselves
B) No, IAS 8's mandatory prior period error correction and restatement requirements apply specifically to material misstatements within the financial statements themselves (amounts and disclosures required by IFRS); a voluntarily disclosed non-financial sustainability metric published outside the financial statements is not itself subject to IAS 8's mandatory restatement mechanism, although the entity may still choose, for consistency, accuracy, or under separate sustainability reporting frameworks, to voluntarily correct and clearly flag the revised figure
C) The entire set of financial statements must be withdrawn and reissued whenever any voluntarily disclosed non-financial metric, however immaterial to the financial statements themselves, is later found to be incorrect
D) The non-financial metric error automatically triggers a corresponding restatement of unrelated financial statement line items, regardless of any actual connection between them

Correct: B complex IAS 8 - scope boundary excluding voluntarily disclosed non-financial metrics outside the financial statements from mandatory restatement

IAS 8's mandatory prior period error correction and restatement mechanism is specifically directed at the financial statements themselves, correcting material misstatements or omissions in amounts and disclosures required by IFRS. A voluntarily disclosed non-financial metric, such as a sustainability or ESG figure published outside the financial statements and their notes, does not fall within this mandatory mechanism at all, even though the entity may reasonably choose to voluntarily correct and clearly flag such a figure for its own consistency and credibility, or in response to separate, non-IFRS sustainability reporting framework requirements that may apply to it independently.

108. An entity modifies an existing property lease, extending its term and adding additional floor space at a rate that reflects the standalone price for the additional space (so the modification does not qualify as a separate new lease under IFRS 16's specific criteria). At the time, the entity incorrectly accounted for the modification as an entirely new, separate lease rather than remeasuring the existing lease liability and right-of-use asset using a revised discount rate, as IFRS 16 actually required in these circumstances. This error is discovered two years later. How is it corrected?

A) This is a prior period error under IAS 8, since IFRS 16's specific criteria for when a lease modification is treated as a separate new lease (rather than a remeasurement of the existing lease) were misapplied to information that was fully known and available at the modification date; the entity retrospectively restates the lease liability and right-of-use asset (and consequential depreciation and interest) as if the modification had been correctly treated as a remeasurement from the outset, rather than continuing to treat the error as an ongoing, uncorrected accounting policy
B) The error is treated as a change in accounting estimate, applied prospectively only from the date of discovery, since lease modifications inherently involve estimation
C) The error can only be corrected once the lease itself terminates or is renewed again
D) No correction is needed, since both approaches ultimately result in a right-of-use asset and lease liability being recognised on the statement of financial position

Correct: A complex IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors / IFRS 16 Leases - lease modification classification error

IFRS 16 sets out specific, largely mechanical criteria for determining whether a lease modification is accounted for as a separate new lease or as a remeasurement of the existing lease - applying the wrong one of these two treatments where the facts (the terms of the modification and the pricing of the additional space) were fully known at the time is a mistake in applying an already-known and available standard and facts, which is precisely IAS 8's definition of a prior period error, not a change in estimate. The correction is retrospective: the lease liability, right-of-use asset, and all consequential depreciation and interest are restated as if the modification had been correctly treated as a remeasurement from the date it actually occurred.

109. An entity sells a bundled product-and-service contract and, at contract inception, incorrectly failed to identify the after-sales service element as a separate, distinct performance obligation under IFRS 15 (treating the entire contract price as relating solely to the product and recognising it all as revenue at the point of delivery), when the service was, in fact, clearly distinct and should have been separately identified and its portion of the transaction price deferred and recognised over the service period. This is discovered a year later. How is this corrected?

A) No correction of any kind is required, since the total revenue recognised over the life of each individual contract will eventually be the same either way
B) As a change in accounting estimate, applied prospectively only to contracts entered into from the date of discovery onward
C) As a retrospective IAS 8 prior period error: the original contracts' facts (the existence and distinctness of the after-sales service) were fully determinable and available at inception using the information reasonably available at the time, so incorrectly failing to identify and separately account for the service performance obligation is a mistake in applying IFRS 15 to already-known facts, requiring retrospective restatement of revenue recognised too early on the affected contracts, deferring the appropriate portion to be recognised over the correct service period
D) The error is corrected only for contracts still open and ongoing at the date of discovery, with no restatement of contracts already fully completed

Correct: C complex IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors / IFRS 15 Revenue from Contracts with Customers - performance obligation identification error

Whether a promised good or service is distinct, and therefore constitutes a separate performance obligation requiring its own portion of the transaction price to be allocated and recognised over its own pattern of delivery, is determined by applying IFRS 15's criteria to the facts of the contract as they existed at inception - facts that were fully available at the time. Incorrectly failing to identify a distinct performance obligation is a mistake applying already-known information, which is precisely an IAS 8 error rather than a change in estimate, and requires retrospective restatement: revenue recognised too early (for the service element) is restated as deferred income and recognised instead over its own correct service period, for all affected periods, not merely from the date of discovery.

110. An entity applied cash flow hedge accounting to a series of forecast foreign currency purchase transactions over the past two years, deferring gains and losses on the hedging instrument in other comprehensive income. It is subsequently discovered that the entity never actually prepared the formal, contemporaneous hedge documentation (identifying the hedging relationship, risk management objective, and effectiveness assessment methodology) required at the inception of each hedging relationship, as IFRS 9 mandates before hedge accounting can be applied at all. How is this discovered failure corrected?

A) The missing documentation is treated as a change in accounting estimate, with hedge accounting simply discontinued prospectively from the date the omission is discovered
B) No correction is needed, since the hedges were, in an economic sense, genuinely effective at offsetting the underlying risk regardless of any missing paperwork
C) Because the mandatory contemporaneous formal documentation was never actually prepared at inception, hedge accounting was never validly achieved for these relationships in the first place under IFRS 9's own strict qualifying criteria, regardless of the hedges' underlying economic effectiveness; this is a prior period error (a mistake applying IFRS 9's own documentation requirement, which was fully known and applicable at the time), requiring retrospective de-designation of hedge accounting and restatement to recognise the hedging instruments' fair value changes in profit or loss for the affected periods instead of in other comprehensive income
D) The entity may retrospectively create the required documentation now, backdated to the original inception dates, to validate the hedge accounting already applied

Correct: C complex IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors / IFRS 9 Financial Instruments - hedge documentation requirement, invalid hedge accounting error

IFRS 9 makes formal, contemporaneous documentation of the hedging relationship at inception a strict, non-negotiable precondition for applying hedge accounting at all - documentation prepared later cannot retroactively validate a hedging relationship, and hedge accounting simply was never validly achieved without it, however economically effective the hedge may have been in substance. Discovering that this mandatory precondition was never met, despite being a fully known and applicable requirement at the time, is a mistake applying an already-known standard - an IAS 8 prior period error - requiring retrospective restatement: fair value changes on the hedging instruments are reclassified from other comprehensive income to profit or loss for all affected periods, since hedge accounting should never have been applied in the first place.

111. It is discovered that an entity has, for the past three years, failed to consolidate an entity in which it holds only 35% of the voting shares but has, in substance, exercised de facto control throughout that period (through its ability to direct the relevant activities via other contractual and practical arrangements, meeting IFRS 10's control definition despite the minority voting stake). The entity had instead accounted for its interest using the equity method as an associate. How is this discovered failure corrected?

A) No correction is required, since the equity method and full consolidation ultimately produce the same profit attributable to the parent's owners
B) As a change in accounting estimate, with full consolidation applied prospectively only from the date the failure is discovered
C) The correction is applied only to the current year's consolidated financial statements, with prior years' equity-accounted figures left permanently unrestated
D) As a retrospective IAS 8 prior period error: the facts giving rise to de facto control (the specific contractual and practical arrangements) existed and were determinable throughout the three-year period using information available at the time, so incorrectly concluding the entity was merely an associate rather than a subsidiary is a mistake applying IFRS 10's control definition to already-known facts, requiring full retrospective consolidation of the subsidiary for all three affected years, replacing the equity-accounted associate figures previously reported

Correct: D complex IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors / IFRS 10 Consolidated Financial Statements - de facto control not recognised, prior period error

Whether an entity has control under IFRS 10 depends on the actual facts and circumstances of its relationship with the investee - including any de facto control arising from practical ability to direct relevant activities, not merely formal voting rights - and those facts existed and were determinable throughout the period in question. Concluding, based on a misapplication of the control definition to already-known facts, that the investee was merely an associate rather than a controlled subsidiary is a prior period error under IAS 8, not a change in estimate, and is corrected by retrospectively consolidating the subsidiary in full for every affected prior period, replacing the previously reported equity-accounted figures (which also affects total assets, liabilities, revenue, and non-controlling interests, not merely the single line of profit attributable to owners that might otherwise coincidentally look similar).

112. A group has a foreign subsidiary operating in a hyperinflationary economy. For the past two years, the subsidiary's financial statements were translated for consolidation purposes without first being restated for the effects of hyperinflation using a general price index, as IAS 29 specifically requires before IAS 21's translation procedures are applied. This omission is discovered in the current year. How is it corrected?

A) As a change in accounting estimate, with hyperinflationary restatement applied prospectively only from the current year onward
B) No correction is needed, since hyperinflation adjustments are inherently estimates rather than corrections of definite errors
C) The correction is applied only to the translation reserve within other comprehensive income, with no effect on any other consolidated figures
D) As a retrospective IAS 8 prior period error: the requirement to first restate the hyperinflationary subsidiary's financial statements for general price-level changes before translation was a fully known and applicable requirement throughout the affected periods (given the economy's already-existing hyperinflationary characteristics), so omitting this step is a mistake applying an already-known standard, requiring retrospective restatement of the subsidiary's financial statements (and the resulting consolidated figures) as if the IAS 29 restatement had been correctly applied throughout the affected periods

Correct: D complex IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors / IAS 29 Financial Reporting in Hyperinflationary Economies - omitted restatement, prior period error

IAS 29 mandates restatement of a hyperinflationary economy's financial statements for the effects of general price-level changes as a specific, mechanical precondition before those statements are translated for consolidation under IAS 21 - this is not a matter of estimation but a defined procedural requirement that either was, or was not, correctly applied to the already-existing facts (the economy's hyperinflationary status) known throughout the affected periods. Omitting the required restatement is a prior period error under IAS 8, corrected by retrospectively restating the subsidiary's financial statements (affecting multiple consolidated balances, including non-monetary assets, equity, and the resulting translated figures), not merely a single reserve or a prospective adjustment.

113. An entity continued capitalising borrowing costs on a qualifying asset under construction for several months after the asset was already substantially complete and available for its intended use, rather than ceasing capitalisation at that point as IAS 23 requires. This over-capitalisation error, which understated depreciation and overstated the asset's carrying amount, is discovered two years later. How is it corrected?

A) As a retrospective IAS 8 prior period error: the date the asset actually became available for its intended use (the point IAS 23 requires capitalisation to cease) was a fact fully determinable at the time using information then available, so continuing to capitalise borrowing costs beyond that point is a mistake applying an already-known requirement to already-known facts, requiring retrospective de-capitalisation of the excess borrowing costs, restatement of the asset's carrying amount, and correction of the consequential understated depreciation charged in each affected period since the asset actually became available for use
B) The error can only be corrected once the asset is eventually disposed of, at which point the full effect is recognised as a single adjustment to the gain or loss on disposal
C) No correction is needed, since the total lifetime cost of the asset (including finance costs) remains economically the same regardless of when capitalisation stopped
D) As a change in accounting estimate, with the excess capitalised borrowing costs simply written off prospectively from the date of discovery with no restatement of prior periods

Correct: A complex IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors / IAS 23 Borrowing Costs - capitalisation continued beyond cessation date, prior period error

IAS 23 requires capitalisation of borrowing costs to cease once substantially all the activities necessary to prepare the qualifying asset for its intended use are complete - the date this occurs is a factual matter, not an estimate, and was fully determinable at the time using information then available. Continuing to capitalise borrowing costs beyond that point is a mistake in applying an already-known standard requirement to already-known facts, which is precisely an IAS 8 prior period error, requiring retrospective correction: the excess capitalised amount is removed from the asset's cost, and the depreciation that should have been charged on the asset's correct (lower) carrying amount since it actually became available for use is retrospectively recognised for all affected periods.

114. An entity revalues a class of buildings under IAS 16's revaluation model but, for several years, has failed to recognise the deferred tax liability arising from the resulting temporary difference between the buildings' higher revalued carrying amount and their unchanged tax base, as IAS 12 requires. This omission is discovered in the current year. How is it corrected?

A) No correction is required, since deferred tax on a revaluation surplus is optional under IAS 12 rather than mandatory
B) As a retrospective IAS 8 prior period error: the requirement to recognise deferred tax on a temporary difference arising from asset revaluation is a specific, well-established requirement of IAS 12 that was fully known and applicable throughout the affected periods, so failing to apply it is a mistake applying an already-known standard, requiring retrospective recognition of the deferred tax liability (recognised, consistent with the original revaluation gain, within the revaluation surplus in other comprehensive income/equity rather than in profit or loss) for all affected periods
C) As a change in accounting estimate, with the deferred tax liability simply recognised prospectively from the current year's revaluation onward
D) The deferred tax liability is recognised only for the current year's revaluation movement, with no restatement of the cumulative revaluation surplus already recognised in prior years

Correct: B complex IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors / IAS 12 Income Taxes - deferred tax on revaluation surplus omitted, prior period error

IAS 12 requires deferred tax to be recognised on essentially all taxable temporary differences, including the difference created when an asset's carrying amount is increased under the IAS 16 revaluation model while its tax base remains unchanged - this is a well-established, mandatory requirement, not an option, and was fully known and applicable throughout the periods in question. Failing to recognise this deferred tax liability is a mistake applying an already-known standard, an IAS 8 prior period error, requiring retrospective recognition of the deferred tax liability for all affected periods; consistent with the origin of the underlying temporary difference (the revaluation gain, itself recognised in other comprehensive income), the related deferred tax is also recognised within the revaluation surplus in equity/OCI, not retrospectively charged through profit or loss.

115. An entity classified a non-current asset as held for sale under IFRS 5 in a prior year and ceased depreciating it accordingly, but it is subsequently discovered that, at the time of that original classification, the asset was not actually available for immediate sale in its then-current condition and a sale was not, in fact, highly probable within one year - meaning the IFRS 5 held-for-sale classification criteria were never actually met at that date. How is this discovered misclassification corrected?

A) As a change in accounting estimate, with depreciation simply resuming prospectively from the date the misclassification is discovered, with no adjustment to prior periods
B) No correction is required, since the asset would eventually have been depreciated in full regardless of the classification error
C) As a retrospective IAS 8 prior period error: whether the specific IFRS 5 criteria (availability for immediate sale, and a highly probable sale within one year) were actually met at the original classification date is a factual question determinable from information available at the time, so incorrectly concluding they were met is a mistake applying an already-known standard to already-known facts, requiring retrospective reversal of the held-for-sale classification and reinstatement of the depreciation that should have continued to be charged throughout the period the asset was incorrectly classified as held for sale
D) The error is corrected only from the date of discovery forward, with the un-depreciated period permanently excluded from any charge

Correct: C complex IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors / IFRS 5 Non-current Assets Held for Sale and Discontinued Operations - classification criteria not met, prior period error

Whether an asset genuinely meets IFRS 5's specific held-for-sale criteria at a given date - available for immediate sale in its present condition, and a sale that is highly probable within one year - is a factual determination based on the circumstances and information existing and available at that time, not a matter of estimation uncertainty. Concluding those criteria were met when, on the facts actually available at the time, they were not, is a mistake applying an already-known standard to already-known facts - an IAS 8 prior period error - requiring retrospective reversal of the incorrect classification and reinstatement of the depreciation charge that should have continued throughout the period the asset was wrongly held out of depreciation.

116. An entity has, for several years, accounted for its 50% interest in a jointly controlled arrangement using the equity method, treating it as a joint venture. It is subsequently discovered that the arrangement's actual legal structure and contractual terms mean the parties have direct rights to the arrangement's individual assets and direct obligations for its individual liabilities (rather than rights only to a net residual interest), meaning the arrangement was, in substance, a joint operation throughout, not a joint venture. How is this discovered misclassification corrected?

A) No correction is required, since both methods result in the same profit ultimately being attributed to the entity
B) The correction applies only to the statement of financial position, with the income statement left unrestated since profit is unaffected
C) As a change in accounting policy, applied prospectively only from the date of discovery, since both the equity method and joint operation accounting are equally acceptable policy choices under IFRS 11
D) As a retrospective IAS 8 prior period error: whether an arrangement is a joint operation or a joint venture depends on the parties' actual rights and obligations under its legal structure and contractual terms, which were fully determinable throughout the period from information available at the time, so incorrectly applying the equity method to what was, in substance, always a joint operation is a mistake applying IFRS 11's classification criteria to already-known facts, requiring retrospective restatement to recognise the entity's own share of the arrangement's assets, liabilities, revenue, and expenses on a line-by-line basis for all affected periods, replacing the single-line equity-accounted investment

Correct: D complex IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors / IFRS 11 Joint Arrangements - joint operation misclassified as a joint venture, prior period error

IFRS 11 classifies a joint arrangement as either a joint operation or a joint venture based on the parties' actual rights and obligations arising from the arrangement's legal structure, contractual terms, and other relevant facts and circumstances - not a free accounting policy choice between the two. Where these facts were fully determinable throughout the period and demonstrate the arrangement was always, in substance, a joint operation, applying the equity method (appropriate only for a joint venture) is a mistake applying IFRS 11's classification criteria to already-known facts - an IAS 8 prior period error - requiring retrospective restatement to recognise the entity's own share of the arrangement's assets, liabilities, revenue, and expenses directly, line by line, for every affected period, materially changing both the statement of financial position and the income statement's gross figures (even where total profit recognised happens to be unaffected).

117. A parent company recognised a liability for a written put option it granted to non-controlling shareholders of a subsidiary, allowing them to sell their remaining shares to the parent at a future date for a formula-based price. It is discovered that the initial measurement of this NCI put liability, recognised two years ago, used an incorrect input in the pricing formula (a data entry mistake in the formula's underlying variable, not a change in any market assumption since then), materially understating the liability from inception. How is this corrected?

A) As a change in accounting estimate, with the liability increased prospectively from the date the error is discovered, with no restatement of prior periods
B) As a retrospective IAS 8 prior period error: the correct value of the input in question was fully determinable at the original measurement date using information available at the time (the error was a data entry mistake, not a subsequent change in a market assumption), so the initial measurement mistake is a prior period error requiring retrospective restatement of the NCI put liability's initial recognition and its subsequent remeasurement history, rather than a prospective correction
C) No correction is needed, since NCI put liabilities are always remeasured to fair value at each reporting date regardless of how they were initially measured
D) The correction is limited to a note disclosure only, with no adjustment to any recognised balances

Correct: B complex IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors - initial measurement error in an NCI put option liability

Although an NCI put liability is indeed remeasured at each subsequent reporting date, this does not cure an error in its original initial measurement: if the mistake was a data entry error in an input that was already correctly determinable at the original measurement date (rather than a genuine subsequent change in a market assumption, which would instead flow through ordinary remeasurement), then the original measurement itself was wrong from the outset. This is a mistake applying already-available information at the time, an IAS 8 prior period error, requiring retrospective restatement of the liability's initial recognition and its entire subsequent remeasurement history to reflect what it should have been throughout, not simply a prospective increase from the date of discovery.

118. A provision was recognised in a prior year for a legal claim, on the basis that management at the time believed an outflow was probable. It is subsequently established, based on a careful review of the specific legal advice and evidence that was actually available at that original reporting date (not new information arising afterward), that a properly informed assessment of that same evidence would have concluded the outflow was, in fact, only possible rather than probable at that time - meaning a provision should never have been recognised at all at that date, only a contingent liability disclosed. How is this discovered over-recognition corrected?

A) No correction is required, since a provision that is subsequently reversed always represents an ordinary change in estimate regardless of why the original assessment was wrong
B) As a retrospective IAS 8 prior period error: because the conclusion that an outflow was probable rests on a flawed assessment of evidence that was already fully available at the original reporting date (rather than reflecting new information that only emerged afterward), recognising the provision in that year was a mistake applying IAS 37's recognition threshold to already-known facts, requiring retrospective reversal of the provision as at that original reporting date and restatement of the prior year's financial statements accordingly
C) The reversal is recognised entirely within the current period's profit or loss with no distinction drawn as to whether the original recognition itself was ever justified
D) As a change in accounting estimate, with the provision simply reversed prospectively in the current period with no restatement of the prior year in which it was originally (incorrectly) recognised

Correct: B complex IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors / IAS 37 Provisions - over-recognition based on a flawed original assessment, distinguished from a change in estimate

Distinguishing a genuine change in accounting estimate from a prior period error turns on whether new information has come to light since the original assessment, or whether the original assessment itself was simply a mistake applying the relevant recognition criteria to information that was already fully available at the time. Where a careful re-examination of the very same evidence that existed at the original reporting date reveals that a properly informed assessment would have concluded the outflow was merely possible (not probable), the original recognition of a provision was itself flawed from the outset - a mistake, not a change in circumstances - and this is an IAS 8 prior period error requiring retrospective reversal of the provision and restatement of the affected prior period, rather than a prospective reversal treated as an ordinary change in estimate.

119. A group's foreign subsidiary's goodwill (arising on its original acquisition several years ago) has, since acquisition, been incorrectly retranslated at the closing rate at each subsequent reporting date using a fundamentally wrong convention: rather than treating goodwill as part of the foreign subsidiary's own net assets (translated at the closing rate, consistent with its non-monetary nature, with exchange differences taken to the translation reserve in OCI, as IFRS 3/IAS 21 require), the group had been leaving the original acquisition-date goodwill figure permanently fixed in the parent's own presentation currency with no translation applied at all. This is discovered in the current year. How is it corrected?

A) No correction is required, since goodwill is not depreciated or amortised and therefore its translation basis is not considered material
B) As a change in accounting estimate, with the correct translation approach applied prospectively only from the current year's closing rate onward
C) The correction is applied only to the translation reserve, with no adjustment to the goodwill balance itself reported on the statement of financial position
D) As a retrospective IAS 8 prior period error: the requirement to treat goodwill arising on a foreign operation's acquisition as an asset of that foreign operation (translated at the closing rate at each reporting date, with resulting exchange differences recognised in the translation reserve within OCI) is an established requirement of IFRS 3/IAS 21 that was fully known and applicable throughout the period, so applying no translation at all is a mistake applying an already-known standard, requiring retrospective restatement of goodwill's translated carrying amount and the cumulative translation reserve for all affected periods

Correct: D complex IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors / IFRS 3 Business Combinations / IAS 21 The Effects of Changes in Foreign Exchange Rates - foreign subsidiary goodwill translation error

Goodwill arising on the acquisition of a foreign operation is treated as an asset of that foreign operation for translation purposes and is therefore translated at the closing rate at each subsequent reporting date, with the resulting exchange differences recognised in the translation reserve within other comprehensive income - this is a settled, mandatory requirement, not a policy choice or estimate. Applying no translation at all, leaving the original acquisition-date figure permanently fixed, is a mistake applying this already-known requirement throughout the period, an IAS 8 prior period error, requiring retrospective restatement of both the goodwill balance itself (as translated at each relevant closing rate) and the cumulative translation reserve in OCI/equity for every affected period, not merely a prospective correction or a reserve-only adjustment.

120. A parent disposed of a 15% interest in a subsidiary two years ago while retaining control (its remaining interest, at 65%, still gives it control), but incorrectly recognised the difference between the sale proceeds received and the carrying amount of the interest disposed of as a gain in the consolidated profit or loss, rather than recognising it directly within equity as a transaction between owners (since control was retained throughout). This is discovered in the current year. How is it corrected?

A) The correction is limited to restating non-controlling interest alone, with no adjustment to the equity attributable to the owners of the parent
B) As a change in accounting estimate, with only the current year's equity adjusted, leaving the previously recognised profit or loss gain unrestated
C) As a retrospective IAS 8 prior period error: whether control was retained after the partial disposal (and therefore whether the correct treatment was a transaction directly within equity rather than a gain in profit or loss) is a factual matter determinable from the actual facts and circumstances existing at the time, so applying the wrong treatment is a mistake applying an already-known requirement of IFRS 10, requiring retrospective restatement to remove the previously recognised gain from profit or loss (and the related comparative earnings per share) and recognise the same amount instead directly within equity attributable to the owners of the parent
D) No correction is required, since total equity is ultimately the same either way, regardless of whether the amount passed through profit or loss on its way there

Correct: C complex IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors / IFRS 10 Consolidated Financial Statements - partial disposal with control retained, equity versus profit or loss treatment error

IFRS 10 requires that where a parent disposes of part of its interest in a subsidiary while retaining control, the difference between the consideration received and the corresponding change in the parent's interest in the subsidiary's net assets (including any adjustment to non-controlling interest) is recognised directly in equity as a transaction between owners in their capacity as owners, not as a gain or loss in profit or loss - control being retained is the determining, factual condition. Applying the wrong treatment where control was, in fact, retained throughout is a mistake applying this already-known requirement, an IAS 8 prior period error, requiring retrospective restatement: the previously recognised profit-or-loss gain (and any resulting overstatement of prior period earnings per share) is removed and the same amount recognised instead directly within equity attributable to the parent's owners, since routing it through profit or loss materially misstates reported performance even though total equity itself may be unaffected.

121. An entity's own shares, repurchased on the open market and held in treasury (not cancelled), were incorrectly recognised as a financial asset (an investment) measured at fair value through profit or loss for the past two years, rather than being deducted directly from equity as IAS 32 requires for an entity's own equity instruments it has reacquired. This error, including the fair value gains and losses recognised in profit or loss on the (incorrectly recognised) asset over that period, is discovered in the current year. How is it corrected?

A) As a change in accounting policy, applied prospectively only from the current year, since both approaches are equally defensible presentation choices for treasury shares
B) As a retrospective IAS 8 prior period error: IAS 32's requirement that an entity's own reacquired equity instruments be deducted directly from equity, with no gain or loss ever recognised in profit or loss on their purchase, sale, issue, or cancellation, is a fundamental and unambiguous requirement that was fully known and applicable throughout the affected periods, so recognising the shares as a financial asset (and any fair value gains and losses on them) is a mistake applying an already-known standard, requiring retrospective restatement to remove the asset and all related profit-or-loss fair value movements, replacing them with a direct deduction from equity
C) The correction only removes the asset from the statement of financial position, with the previously recognised fair value gains and losses in profit or loss left as reported in each of the affected prior periods
D) No correction is required, since the shares remain within the group's overall net assets either way and the presentation makes no substantive difference

Correct: B complex IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors / IAS 32 Financial Instruments: Presentation - treasury shares incorrectly recognised as a financial asset, prior period error

IAS 32 is unambiguous and fundamental in its treatment of an entity's own equity instruments that it reacquires and holds (treasury shares): they are deducted directly from equity, and no gain or loss is ever recognised in profit or loss on the purchase, sale, issue, or cancellation of an entity's own equity instruments - this is not a policy choice between competing acceptable presentations. Recognising them instead as a financial asset measured at fair value through profit or loss, and recognising fair value gains and losses on them, is a mistake applying this already-known and unambiguous requirement, an IAS 8 prior period error, requiring full retrospective restatement: the incorrectly recognised asset is removed and replaced with a direct deduction from equity, and all of the previously recognised profit-or-loss fair value movements on it are also reversed and restated as part of the correction, not left standing in the comparative figures.

122. At the prior year end, an impairment loss had been recognised on a cash-generating unit under IAS 36, reducing the carrying amount of its property and equipment. During the current year, it comes to light that at the prior reporting date there was already clear, available evidence (a signed customer contract renewal, known to management at the time) indicating the recoverable amount had in fact recovered above the impaired carrying amount for one of the unit's assets, but this evidence was simply overlooked when the prior year impairment test was finalised, so no reversal was recognised even though one was already required based on facts existing at that date. This is discovered in the current year. How should this be treated, and how does it differ from an impairment reversal based on genuinely new information arising after the prior year end?

A) As a retrospective IAS 8 prior period error: because the evidence supporting the reversal already existed and was available at the prior reporting date and was simply overlooked, this is a mistake in applying IAS 36 to already-known facts, not a change in estimate, so it requires retrospective restatement of the prior period impairment reversal and depreciation, in contrast to a reversal driven by facts arising only after that date, which would properly be recognised prospectively as a change in estimate in the period the new information arises
B) As a voluntary change in accounting policy, applied retrospectively, since the entity is changing its approach to assessing impairment reversal indicators
C) As a change in accounting estimate, recognised prospectively in the current year's profit or loss only, since impairment reversals are always estimate-based revisions regardless of when the underlying evidence existed
D) No correction is possible, since IAS 36 impairment reversals can only ever be recognised in the period identified regardless of when the underlying evidence arose

Correct: A complex IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors / IAS 36 Impairment of Assets - omitted impairment reversal based on already-existing evidence, error versus change in estimate

IAS 8 distinguishes an error (a mistake in applying already-known, available facts at the relevant prior date) from a change in estimate (a revision triggered by new information or developments arising after that date). Here, the customer contract renewal evidence existed and was known to management at the prior reporting date but was simply overlooked when finalising the impairment test, so the omitted reversal is a prior period error requiring retrospective restatement of the impairment reversal and the resulting depreciation in the affected prior period. Had the recoverable amount instead recovered because of genuinely new developments arising only after the prior year end, that would properly be recognised prospectively as a change in accounting estimate in the current period, with no restatement of the prior period.

123. An entity amends the terms of its defined benefit pension plan, creating past service cost that IAS 19 requires to be recognised immediately in profit or loss in the period of the amendment. Due to a clerical error in recording the amendment's legally effective date, the past service cost was instead recognised one full accounting period later than it should have been. How should this be corrected once discovered?

A) As a change in accounting policy under IAS 8, since the plan amendment itself changed the terms of the defined benefit obligation.
B) As a change in accounting estimate under IAS 8, applied prospectively from the period the error is discovered, since it relates to the timing of a pension-related amount.
C) No correction is required at all, since the total cumulative past service cost recognised over the two periods combined is the same regardless of which period it falls into.
D) As a prior period error under IAS 8, since the mistake was applying an incorrect effective date to information (the amendment's actual legal terms) that was already available at the time, requiring retrospective restatement of the period in which the past service cost should have been recognised.

Correct: D complex IAS 19 Employee Benefits, paragraph 103; IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors, paragraphs 41-49

The past service cost's correct recognition date was determinable from the amendment's own legal terms, which were available at the time; recording it a period late reflects a clerical mistake applying already-available information, the defining characteristic of a prior period error rather than a change in estimate (which reflects new information) or a change in policy (which reflects a different but equally acceptable method). It is corrected under IAS 8 by retrospectively restating the period in which the cost should have been recognised, even though the cumulative two-period total is unaffected, since each individual period's results were still genuinely misstated.

124. An insurer discovers that, at transition to IFRS 17, it used an incorrect discount rate curve, one that did not properly reflect the characteristics of the insurance contract liabilities being measured, causing the transition-date insurance contract liabilities to be materially misstated. This is discovered only after several subsequent annual reports have already been issued using the incorrect curve. How should this be corrected?

A) As a prospective change in accounting estimate, applied only from the current period onward, since discount rate curves are inherently estimation-based inputs.
B) No correction is possible once the transition date has passed, since IFRS 17 transition balances are fixed permanently once the first set of financial statements under the standard is issued.
C) As a retrospective IAS 8 prior period error, since the incorrect curve reflected a mistake applying the IFRS 17 discount rate requirements to information available at transition, requiring restatement of the transition-date liabilities and all affected subsequent comparative periods.
D) As a change in accounting policy, since the discount rate curve methodology itself is being changed.

Correct: C complex IFRS 17 Insurance Contracts, discount rate requirements, paragraphs 36, B72-B85; IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors, paragraphs 41-49

Although selecting a discount rate involves judgement, using a curve that did not properly reflect the required characteristics of the liabilities at transition was a mistake in applying IFRS 17's own requirements to information that was available at the time, not new information emerging later; this makes it a prior period error rather than a change in estimate. It is corrected under IAS 8 by retrospectively restating the transition-date balances and every subsequently affected comparative period, in the same way as any other material error traced back to a specific origin date.

125. An agricultural entity measures its herd of biological assets at fair value less costs to sell, using a published commodity market price index as a key input. It is later discovered that, for several prior reporting periods, the valuation model used the wrong specific market price index, one relating to a different, non-comparable commodity, an input error rather than any change in the underlying valuation methodology itself. How should this be corrected?

A) No restatement is required, since IAS 41 fair value movements are recognised in profit or loss in the period they occur regardless of which index was used to derive them.
B) As a change in accounting policy, since a different market price index is now being used going forward.
C) As a prior period error under IAS 8, since using the wrong specific index was a mistake in applying the valuation model correctly with information that was available at each affected reporting date, requiring retrospective restatement.
D) As a change in accounting estimate, applied prospectively only, since fair value measurement of biological assets is inherently an estimation exercise.

Correct: C complex IAS 41 Agriculture, paragraphs 12-13; IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors, paragraphs 41-49

The valuation methodology itself, using a published commodity market price index as a key input to a fair value less costs to sell measurement, was correct and unchanged; the error lay in selecting the wrong specific index, one that did not actually relate to the commodity in question, a mistake in applying an available and correct input, not new information emerging later or a change in the valuation method. This is a prior period error under IAS 8, corrected by retrospectively restating each affected period's biological asset valuation and related profit or loss using the correct index.
