126. A manufacturing entity has, for several consecutive years, applied a fixed predetermined production overhead absorption rate to value closing inventory, a rate that was calculated using outdated, no-longer-representative budgeted activity levels from many years earlier and was never subsequently reviewed or updated, causing closing inventory to be consistently and materially overstated across all of those years. How should this systemic overhead absorption error be corrected once identified?

A) As an IAS 8 prior period error, since the entity's own established costing policy (to use a periodically reviewed, representative overhead absorption rate) was not actually being applied correctly, the rate having become stale and unreviewed rather than reflecting a deliberate, reasonable estimate at each relevant reporting date, requiring retrospective restatement of the affected periods' inventory and cost of sales.
B) As a change in accounting estimate, applied only prospectively from the period of discovery, since any overhead absorption rate is inherently an estimate.
C) As a change in accounting policy, since a different overhead absorption methodology will be used going forward.
D) No correction is required, since consistent application of the same rate across all affected years means the error, being systemic, is not material to any individual period.

Correct: A complex IAS 2 Inventories, paragraphs 12-13; IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors, paragraphs 41-49

A defensible overhead absorption rate reflects a genuine, periodically reviewed estimate of budgeted activity and costs; here, the rate was simply never reviewed or updated, becoming systematically wrong rather than reflecting new information at each relevant date. This distinguishes the situation from an ordinary, evolving change in estimate and instead reflects a failure to apply the entity's own costing policy correctly and consistently, a prior period error requiring retrospective restatement of inventory and cost of sales for each materially affected period, notwithstanding that the same mistake recurred systemically across several years.

127. A group entity changes its presentation currency, the currency in which it chooses to present its financial statements, from one currency to another, while its functional currency remains entirely unchanged. How does IAS 21 require this change in presentation currency to be applied, and how does this differ from a genuine change in functional currency?

A) A change in presentation currency can never be made at all once financial statements have first been issued in a particular presentation currency.
B) A change in presentation currency is applied fully retrospectively, as though the new presentation currency had always been used, translating all prior period figures into the new currency for comparative purposes, whereas a genuine change in functional currency is applied prospectively from the date the underlying change in circumstances actually occurs, translating only from that date forward using the procedures applicable to a change in functional currency.
C) Both changes are treated as IAS 8 prior period errors, requiring restatement of opening retained earnings for the earliest period presented in every case.
D) Both a change in presentation currency and a change in functional currency are applied prospectively from the date of change, with no restatement of prior periods in either case.

Correct: B complex IAS 21 The Effects of Changes in Foreign Exchange Rates, paragraphs 35-37, 54-58

IAS 21 draws a clear distinction between these two different changes: a change in presentation currency is simply a change in the currency used to present already-existing functional currency results and is applied by translating the financial statements, including all comparatives, into the new presentation currency as though it had always been the presentation currency used, a fully retrospective translation exercise. A genuine change in functional currency, by contrast, reflects an actual change in the primary economic environment in which the entity operates and is applied prospectively from the date that underlying change occurs, since restating prior periods for a functional currency that did not yet apply to them would not be meaningful.

128. A long-term services contract includes a significant bonus payable to the entity if a project milestone is achieved by a specified date. In a prior period, the entity recognised the full bonus amount as revenue immediately, even though, applying IFRS 15's variable consideration constraint, it was not highly probable at that time that a significant reversal of revenue would not occur if the milestone were ultimately missed given known, significant uncertainties. The milestone is later missed and the bonus is never earned. How should the original over-recognition be corrected?

A) No correction is required to any prior period, since the milestone was always going to be resolved eventually and the final outcome, once known, is simply recognised when it occurs.
B) As a change in accounting policy, since the entity is now applying a more constrained approach to recognising variable consideration.
C) As a prior period error under IAS 8, since the entity failed to apply the variable consideration constraint correctly to circumstances and evidence that already existed at the time revenue was originally recognised, requiring retrospective restatement of the period in which the bonus was over-recognised.
D) As a change in accounting estimate, applied prospectively only in the period the milestone is actually missed, since the ultimate outcome of the milestone was always uncertain.

Correct: C complex IFRS 15 Revenue from Contracts with Customers, paragraphs 56-58; IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors, paragraphs 41-49

IFRS 15's constraint on variable consideration requires an entity to estimate variable consideration only to the extent it is highly probable a significant reversal will not occur, based on the facts and circumstances existing at the time revenue is recognised. Recognising the full bonus despite already-known significant uncertainty about whether the milestone would be met was a mistake applying that constraint to information available at the time, not a change reflecting new information emerging later, and is therefore corrected as a prior period error, restating the period the revenue was originally over-recognised.

129. A lessee incurred significant initial direct costs in arranging a new lease, costs that IFRS 16 requires to be added to the initial measurement of the right-of-use asset rather than expensed immediately. Due to a misunderstanding of the standard's requirements, the entity instead expensed these costs immediately in the period the lease commenced. This is discovered two years later. How should this be corrected?

A) As a prior period error under IAS 8, since the entity misapplied IFRS 16's initial measurement requirements to information that was fully available at lease commencement, requiring retrospective restatement to capitalise the costs within the right-of-use asset, reconstruct the depreciation that should have been charged in each affected period, and restate opening retained earnings accordingly.
B) No correction is required, since initial direct costs are relatively minor in the context of the overall lease liability and right-of-use asset.
C) As a change in accounting estimate, applied prospectively, adjusting only the depreciation charge for the current and future periods without restating the original expensing.
D) As a change in accounting policy, since the entity is now applying a different treatment to initial direct costs going forward.

Correct: A complex IFRS 16 Leases, paragraph 24; IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors, paragraphs 41-49

The requirement to capitalise initial direct costs within the right-of-use asset is a clear, unambiguous measurement rule in IFRS 16, and the information needed to apply it correctly, the nature and amount of the costs incurred at commencement, was fully available at that time; expensing them immediately instead reflects a misapplication of the standard's requirements, not new information emerging later, making this a prior period error. Correction requires retrospectively capitalising the costs, reconstructing the additional depreciation that should have been charged in each affected period, and restating opening retained earnings for the earliest period presented.

130. An entity's stated accounting policy is to present government grants related to income as a separate line of other income within profit or loss, rather than netting them against the related expense. For one particular grant, contrary to this stated policy, the grant was instead recognised as a direct reduction of the associated expense line, an inconsistency discovered a year later, with no effect on the entity's total reported profit for the affected period since both presentations arrive at the same bottom line. Does this require correction under IAS 8?

A) Yes, but only through a prospective change in policy applied from the current period forward, since presentation-only issues are never restated retrospectively.
B) Yes, since a material inconsistency between the entity's own stated accounting policy and how a specific transaction was actually presented is still a prior period error for IAS 8 purposes if material to the financial statements as a whole, even where total profit is unaffected, since IAS 8 errors are not confined only to items that change a bottom-line total; the comparative presentation should be restated to reflect the entity's correct, consistently applied policy.
C) No, since there is no effect whatsoever on total profit or loss or on any total reported in the primary financial statements, only a presentation matter within the income statement.
D) No, since IAS 20 does not require gross presentation to be applied consistently, meaning either treatment is equally acceptable in every period regardless of the entity's stated policy.

Correct: B complex IAS 20 Accounting for Government Grants and Disclosure of Government Assistance, paragraph 29; IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors, paragraphs 5, 41-49

IAS 8 recognises that a material error need not have any effect on a bottom-line total, such as total profit or total equity, to still require correction; a material inconsistency between an entity's own stated and applied policy, here presenting a particular grant net against its expense contrary to the entity's own established gross-presentation policy, is corrected as a prior period error if material to the financial statements as a whole, with the comparative figures restated to reflect the policy consistently, even though total reported profit for the period is unaffected either way.

131. An entity holds an investment property measured under the fair value model in accordance with IAS 40. For several prior periods, its accounting staff, apparently confusing the requirements with those applicable to owner-occupied property under the cost model, incorrectly charged annual depreciation on the investment property in addition to recognising fair value gains and losses. This is discovered by a new finance director. How should this be corrected?

A) As a change in accounting estimate, applied prospectively, simply ceasing to charge depreciation from the current period onward with no restatement of the amounts already charged.
B) No correction is required, since fair value gains and losses already reflect the property's true value regardless of any depreciation additionally charged alongside them.
C) As a change in accounting policy, since the entity is now applying the fair value model without depreciation.
D) As a prior period error under IAS 8, since IAS 40 does not permit depreciation of an investment property measured under the fair value model at all, meaning the depreciation charged in each affected prior period was a straightforward misapplication of a clear, unambiguous requirement that was fully known at the time, requiring retrospective restatement to remove the depreciation and restate the investment property and profit or loss for each affected period.

Correct: D complex IAS 40 Investment Property, paragraph 79; IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors, paragraphs 41-49

IAS 40's fair value model is explicit that no depreciation is charged, since changes in fair value already capture the property's changing value in full; charging depreciation on top of fair value movements directly contradicts this clear, unambiguous requirement, a straightforward mistake applying a rule that was fully known and available at the time, rather than any kind of estimation or policy choice. It is corrected as a prior period error, reversing the depreciation charged in each affected period, restating the investment property's carrying amount (limited to correcting the erroneous depreciation, since fair value gains and losses themselves were separately and correctly measured) and profit or loss accordingly.

132. A borrower renegotiates the terms of an existing loan with its lender. The renegotiation is correctly assessed as non-substantial, meaning the original financial liability continues to be recognised rather than being derecognised and replaced with a new one. However, in calculating the immediate modification gain or loss and the revised carrying amount, the entity mistakenly discounted the loan's original contractual cash flows at the original effective interest rate, rather than discounting the revised contractual cash flows at that same original effective interest rate, understating the immediate modification gain that should have been recognised. How should this calculation error be corrected once identified in a later period?

A) No correction is required, since the loan's final maturity redemption amount is unaffected regardless of which cash flows were used in the interim calculation.
B) As a change in accounting estimate, applied prospectively from the period of discovery, since the calculation involves discounting future cash flows.
C) As a change in accounting policy, since a different discounting approach will now be applied to the loan going forward.
D) As a prior period error under IAS 8, since the correct mechanics for calculating a non-substantial modification gain or loss, discounting the revised cash flows at the original effective interest rate, were clearly established and available at the time, and using the original (unmodified) cash flows instead was simply a computational mistake, requiring retrospective restatement of the modification gain or loss and the loan's subsequent carrying amount and effective interest.

Correct: D complex IFRS 9 Financial Instruments, paragraph 5.4.3 and B5.4.6; IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors, paragraphs 41-49

IFRS 9 sets out a clear mechanical requirement for a non-substantial modification: the revised (post-modification) contractual cash flows are discounted at the loan's original effective interest rate, with any difference from the existing carrying amount recognised immediately as a modification gain or loss. Using the original, pre-modification cash flows instead was a computational mistake applying an established, unambiguous requirement, not a change in estimate or policy, and is corrected as a prior period error, restating the modification gain or loss and the loan's subsequent amortised cost carrying amount and effective interest recognised in each affected period.

133. An entity measured a non-financial asset at fair value using an income-approach valuation technique (a discounted cash flow model), classifying the resulting measurement within Level 3 of the fair value hierarchy, on the stated basis that no market-based inputs were available. It is later discovered that directly observable, sufficiently comparable market transaction data actually existed at each of those measurement dates, data that would have supported a market-approach technique and a Level 2 classification with a materially different fair value outcome. How should this be corrected?

A) No correction is required, since IFRS 13 permits an entity to choose either a market approach or an income approach regardless of whether comparable market data exists.
B) As a prior period error under IAS 8, since the entity failed to identify and use market data that was, in fact, already available at each measurement date, a mistake applying IFRS 13's hierarchy and valuation technique requirements to information that existed at the time, requiring retrospective restatement of the affected fair value measurements.
C) As a change in accounting estimate, applied prospectively only, since selecting a valuation technique and fair value hierarchy level is inherently a matter of judgement at each reporting date.
D) As a change in accounting policy, since the entity is now applying a different valuation technique to the asset going forward.

Correct: B complex IFRS 13 Fair Value Measurement, paragraphs 61, 72-90; IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors, paragraphs 41-49

IFRS 13 requires an entity to maximise the use of relevant observable inputs and to use a market approach where sufficiently comparable observable market data exists, rather than defaulting to an income approach and a lower, less-observable hierarchy level. Failing to identify data that in fact already existed at each measurement date is a mistake applying that requirement to available information, not new information subsequently emerging, and so is corrected as a prior period error, restating the fair value measurements and any related gains or losses recognised in each affected period.

134. An entity's cash-generating unit (CGU) structure for impairment testing purposes was originally defined at too aggregated a level, combining two operations that, in substance, generate largely independent cash inflows and are managed and monitored separately by senior management, rather than being tested as smaller, separate CGUs as the entity's own internal reporting structure and cash flow independence would properly support. This is discovered several years after the structure was first established, having affected multiple impairment tests in the interim. How should this be corrected?

A) As a prior period error under IAS 8, since identifying the smallest identifiable group of assets generating largely independent cash inflows is a requirement based on facts (the operations' actual independence and management structure) that existed throughout the affected periods, meaning using too aggregated a structure was a mistake applying that requirement, requiring retrospective restatement of each affected period's impairment testing and any resulting impairment losses.
B) As a change in accounting policy, since a different CGU structure will now be used going forward.
C) As a change in accounting estimate, applied prospectively only, adopting the correct, more disaggregated CGU structure from the current period forward with no restatement of prior impairment tests.
D) No correction is required, since CGU identification is inherently judgemental and any reasonable structure chosen by management is acceptable regardless of subsequent findings.

Correct: A complex IAS 36 Impairment of Assets, paragraphs 68-72; IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors, paragraphs 41-49

The correct level at which to identify a CGU depends on objective facts, the smallest identifiable group of assets that generates cash inflows that are largely independent of other assets or groups, which existed throughout the affected periods rather than changing over time; using too aggregated a structure despite the operations' actual independence and separate management was therefore a mistake applying IAS 36's own identification criteria to already-existing facts, not a change in estimate or policy. It is corrected as a prior period error, restating each affected period's impairment testing at the correct, more disaggregated CGU level and any resulting impairment losses that should have been recognised.

135. In accounting for a business combination, contingent consideration payable to the former owners was originally classified as equity, on the basis that it would be settled in the acquirer's own shares. It is later discovered that the actual contractual terms specify a variable number of shares to be issued, calculated by reference to the acquiree's post-acquisition earnings, a feature that fails the fixed-for-fixed test and should have resulted in liability classification with subsequent fair value remeasurement through profit or loss. How should this original misclassification be corrected once identified?

A) As a change in accounting estimate, applied prospectively from the date of discovery, reclassifying the instrument to a liability only from that point forward.
B) As a change in accounting policy, since the entity is now applying a different classification approach to contingent consideration.
C) As a prior period error under IAS 8, since the actual contractual terms, including the variable share-number feature, were fully available and determinable at the acquisition date itself, meaning the original equity classification was a mistake applying IAS 32's fixed-for-fixed test to already-known contract terms, requiring retrospective reclassification to a liability, remeasurement through profit or loss in each affected period, and restatement of opening retained earnings and equity.
D) No correction is required, since the classification of contingent consideration in a business combination, once made at the acquisition date, cannot subsequently be revisited under any circumstances.

Correct: C complex IAS 32 Financial Instruments: Presentation, paragraph 16; IFRS 3 Business Combinations, paragraph 40; IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors, paragraphs 41-49

The contractual terms of the contingent consideration, including the fact that the number of shares issuable varies with the acquiree's post-acquisition earnings rather than being fixed, were fully determinable from the acquisition agreement itself at the acquisition date; classifying the arrangement as equity despite this variable feature was a mistake applying IAS 32's fixed-for-fixed test to already-available information, not a change in estimate or policy. It is corrected as a prior period error, reclassifying the instrument as a liability from the acquisition date, recognising the fair value remeasurements through profit or loss that should have been recognised in each affected period, and restating opening retained earnings and equity for the earliest period presented.

136. A parent entity holds 45 percent of the voting rights of an investee directly, and also holds options, currently exercisable at a modest, non-punitive exercise price, to acquire a further 15 percent of the investee's voting rights from another shareholder. When originally assessing control at acquisition, the entity considered only its direct 45 percent voting interest and concluded it did not control the investee, without considering whether the currently exercisable options gave it the practical ability to direct the investee's relevant activities. It is later determined that, considering those options, the entity did in substance control the investee from the outset. How should this be corrected?

A) As a prior period error under IAS 8, since IFRS 10 requires currently exercisable potential voting rights to be considered as part of the original control assessment, information that was fully available at the acquisition date, meaning the entity's original assessment applied the standard's own requirements incorrectly, requiring retrospective restatement to full consolidation from the acquisition date.
B) No correction is required, since holding options over additional voting rights, rather than actually exercising them, can never be relevant to a control assessment under IFRS 10.
C) As a change in accounting policy, since the entity is now applying a different approach to assessing control.
D) As a change in accounting estimate, applied prospectively, consolidating the investee only from the date the potential voting rights issue is identified.

Correct: A complex IFRS 10 Consolidated Financial Statements, paragraphs B47-B50; IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors, paragraphs 41-49

IFRS 10 explicitly requires an entity to consider currently exercisable potential voting rights, such as options with a non-punitive exercise price, alongside its existing voting interest when assessing control; the existence, terms and exercisability of the options were fully known and available at the acquisition date. Failing to factor them into the original control assessment was therefore a mistake applying IFRS 10's own requirements to already-available facts, a prior period error, corrected by retrospectively consolidating the investee from the acquisition date, restating each affected period's consolidated results, and adjusting opening retained earnings and non-controlling interests accordingly.

137. A disposal group was classified as held for sale under IFRS 5 and measured at the lower of its carrying amount and fair value less costs to sell. It is later discovered that the fair value used at the classification date was based on an independent valuation carried out several months before the actual classification date, without updating it for market movements that had occurred in the intervening period and that were already reasonably determinable at the classification date itself. How should this stale valuation error be corrected?

A) As a change in accounting estimate, applied prospectively only, adjusting the disposal group's carrying amount only in the period the stale valuation is identified, with no restatement of the original classification period.
B) No correction is required, since any independent valuation obtained reasonably close to the classification date is always acceptable regardless of subsequent market movements.
C) As a change in accounting policy, since a different valuation timing approach will now be applied to future disposal groups.
D) As a prior period error under IAS 8, since IFRS 5 requires fair value less costs to sell to be measured as at the classification date itself, and using an outdated valuation without updating it for already-determinable market movements was a mistake applying that measurement date requirement, requiring retrospective restatement of the disposal group's measurement in the affected period.

Correct: D complex IFRS 5 Non-current Assets Held for Sale and Discontinued Operations, paragraphs 6, 15; IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors, paragraphs 41-49

IFRS 5 measures fair value less costs to sell as at the classification date, reflecting conditions and information existing at that date; using an independent valuation performed several months earlier, without updating it for market movements that had already occurred and were reasonably determinable by the classification date, is a mistake applying that measurement date requirement to information that was, in substance, already available. It is corrected as a prior period error, restating the disposal group's measurement, and any related gain or loss, in the period originally affected.

138. A company's Zakat liability for several prior years was calculated using the wrong base figure (mistakenly using net profit rather than the specific net assets/wealth base actually required under the company's own established Zakat computation methodology, a methodology already settled and known at the time), resulting in an understatement of Zakat expense and liability for those years. The error is discovered in the current year. How should this be corrected?

A) Corrected by adjusting only the current year's opening Zakat payable balance, with no corresponding adjustment to retained earnings or the income statement of any period
B) Not corrected at all, since Zakat is treated as being outside the scope of IAS 8's error-correction requirements as a religious rather than a purely statutory obligation
C) Corrected prospectively only, adjusting the current year's Zakat charge alone to catch up for the cumulative prior shortfall, with no restatement of prior periods
D) Corrected retrospectively as a material IAS 8 prior period error, restating each affected prior period's Zakat expense and liability (and the opening balance of retained earnings for the earliest period presented), since this was a mistake in applying an already-established and known computation methodology, not a change in accounting policy or estimate reflecting new information

Correct: D difficult IAS 8 - Zakat calculation base error, retrospective prior period error correction

A mistake in applying an already-established, known computation methodology (using the wrong base figure for a liability whose correct basis was already settled and known at the time) is a classic IAS 8 error, not a change in accounting policy or a change in estimate reflecting new information; it is therefore corrected retrospectively, restating each affected prior period's Zakat expense and liability, and adjusting the opening balance of retained earnings for the earliest period presented, in the same way as any other material prior period error.

139. A company's Workers' Profit Participation Fund (WPPF) accrual, statutorily required at 5% of qualifying net profit under the Bangladesh Labour Act, was calculated for several prior years using a profit figure that incorrectly excluded a material component of qualifying profit that should, under the statute's own clear and already-known definition, have been included in the base. This understated the WPPF accrual and expense in each of those years. How should this be corrected upon discovery?

A) Corrected only within the disclosure notes, with no adjustment to any primary financial statement figures for any period
B) Corrected retrospectively as a material IAS 8 prior period error - since the statutory definition of the qualifying profit base was already clear and known at the time each affected computation was made, the exclusion was a mistake in applying already-available information, requiring restatement of each affected prior period's WPPF expense and liability and the opening retained earnings balance for the earliest period presented
C) No correction of any kind is required, since WPPF is regarded as a distribution of profit to employees rather than an expense subject to IAS 8's error-correction requirements
D) Corrected prospectively by increasing the current year's WPPF percentage rate temporarily to compensate for the historical shortfall, with prior years left unrestated

Correct: B difficult IAS 8 - WPPF statutory profit-participation base error, retrospective prior period error correction

Where a statutory profit-participation obligation's calculation base was already clearly defined and known at the time of each affected computation, an error in applying that known definition (here, incorrectly excluding a component of qualifying profit that should have been included) is a mistake applying already-available information - a classic IAS 8 error - requiring retrospective restatement of each affected prior period's WPPF expense and liability, and the opening retained earnings balance for the earliest period presented, rather than a prospective catch-up or a mere disclosure-only correction.

140. A bank's internal credit risk team discovers that a specific loan account had, for several prior reporting periods, been misclassified within the bank's regulatory loan classification system as 'Standard' when the borrower's own actual repayment behaviour (evidence already fully available and known at each of those prior reporting dates) clearly met the regulator's own criteria for classification as 'Sub-Standard', resulting in an understated regulatory provisioning charge and an understated expected credit loss allowance under IFRS 9 for each of those periods (since the misclassification also fed into internal IFRS 9 staging). How should this be corrected?

A) Corrected retrospectively as a material IAS 8 prior period error for each affected prior period, since the borrower's actual repayment behaviour supporting the correct classification was already fully available and known at each of those prior reporting dates - this is a mistake in applying already-known evidence, not a change in estimate reflecting genuinely new information, and both the regulatory provisioning appropriation and the IFRS 9 ECL allowance for each affected period are restated accordingly
B) The error is left entirely uncorrected, since loan classification is regarded as a purely internal risk management matter with no financial reporting consequence
C) Corrected prospectively only, reclassifying the loan and increasing the provisioning charge and ECL allowance starting from the current period, leaving prior periods unrestated since credit classification inherently involves judgement
D) Corrected by adjusting only the regulatory provisioning appropriation within equity, leaving the IFRS 9 ECL allowance and profit or loss for all prior periods entirely unchanged

Correct: A difficult IAS 8/IFRS 9 - bank loan classification error based on already-known evidence, retrospective correction of provisioning and ECL

Where the evidence supporting a loan's correct regulatory classification (and the resulting IFRS 9 staging) was already fully available and known at each prior reporting date, a misclassification based on that already-available evidence is a mistake in applying known facts - a genuine IAS 8 error - distinguished from a change in estimate that would instead reflect genuinely new information not available at the time; it is corrected retrospectively, restating both the regulatory provisioning appropriation and the IFRS 9 expected credit loss allowance (and the related profit or loss impact) for each affected prior period.

141. A Sukuk-issuing entity discovers that the profit-sharing ratio between the Sukuk holders and the entity itself, as actually specified in the Sukuk's own governing legal documentation at issuance, was different from the ratio the entity had been using in its own internal profit distribution and accounting calculations for several prior periods, due to a data entry error when the terms were first set up in the entity's own systems (the correct ratio was clearly and unambiguously stated in the original legal documentation throughout). How should this be corrected?

A) Corrected prospectively only, applying the correct ratio from the current period onward, since Sukuk profit-sharing ratios are considered a matter of ongoing estimate
B) No correction is made, since Sukuk holders bear investment risk and any resulting under- or over-payment is considered their own risk to absorb under Islamic profit-sharing principles
C) Corrected retrospectively as a material IAS 8 prior period error, restating each affected prior period's Sukuk profit distribution expense/liability using the ratio actually specified in the original governing legal documentation, since the correct ratio was clearly and unambiguously available from inception and the discrepancy arose purely from an internal data entry mistake, not from any genuine ambiguity or subsequent change in terms
D) The correction is made only to the balance sheet liability figure at the current year end, with no restatement of any prior period's profit distribution expense

Correct: C difficult IAS 8 - Sukuk profit-sharing ratio data entry error, retrospective prior period error correction

Where the correct profit-sharing ratio was clearly and unambiguously specified in the Sukuk's own governing legal documentation from inception, and the discrepancy in the entity's own calculations arose purely from an internal data entry error rather than any genuine ambiguity in the terms or a subsequent legitimate change, this is a straightforward IAS 8 error - a mistake applying already-known, available information - requiring retrospective restatement of each affected prior period's Sukuk profit distribution expense and liability using the ratio actually specified in the governing documentation.

142. A group's foreign subsidiary translation process was found to have used, for several prior periods, an incorrect central bank reference exchange rate (a rate for a DIFFERENT, similarly-named currency pair, mistakenly selected from the central bank's published rate table due to a lookup error) rather than the actual applicable closing rate for the subsidiary's own functional currency, materially misstating the translated net assets and the resulting translation reserve for each of those periods. How should this be corrected?

A) Corrected prospectively only, applying the correct rate from the current period's translation onward, with the cumulative prior misstatement absorbed into the current period's translation reserve movement
B) No restatement of prior periods is required, since exchange rate determination is inherently an area of significant estimation uncertainty exempted from IAS 8's error-correction requirements
C) The error is corrected through profit or loss in the current period, since all foreign exchange corrections are recognised in profit or loss regardless of where the original item was recognised
D) Corrected retrospectively as a material IAS 8 prior period error - since the mistake was a straightforward lookup error selecting the wrong published rate from an available, already-published rate table rather than any genuine difficulty in determining the correct rate - restating the translated net assets and translation reserve (in OCI/equity, where the original translation difference was recognised) for each affected prior period

Correct: D difficult IAS 8/IAS 21 - wrong published reference exchange rate used for translation, retrospective correction of the translation reserve

A straightforward lookup error selecting the wrong published exchange rate (rather than any genuine difficulty or judgement in determining the correct rate, which was in fact readily available from the central bank's own published table) is a classic IAS 8 error; it is corrected retrospectively, restating the affected prior periods' translated net assets and the TRANSLATION RESERVE specifically (within OCI/equity), since that is where the original (incorrect) translation difference was recognised - consistent with the general principle that a prior period error is corrected within the same component of equity or profit or loss where the original item was recognised, not automatically routed through profit or loss.

143. An exporter's VAT/duty drawback claims (a refund of import duty paid on inputs used in producing exported goods) were calculated for several prior periods using a stale, superseded statutory drawback rate table that the tax authority had, in fact, already formally updated and published well before those claims were made, resulting in the exporter under-claiming (and therefore understating a receivable and overstating an expense) for those periods. How should this be corrected upon discovery?

A) Corrected retrospectively as a material IAS 8 prior period error, recognising the additional drawback receivable (and reversing the corresponding overstated expense) for each affected prior period using the ALREADY-PUBLISHED correct rate table that was available at the time, since using a stale, already-superseded rate table when the correct, updated table was already published and available is a mistake applying already-available information, not a change in estimate
B) No correction is made and no additional claim is pursued, since drawback claims not made within the original claim period are considered permanently forfeited with no financial reporting consequence
C) Corrected prospectively only, with the current period's drawback claims calculated at the correct rate but no adjustment made for any prior period's understatement
D) The additional drawback amount is recognised entirely as other comprehensive income rather than through profit or loss, since it relates to a tax matter

Correct: A difficult IAS 8 - duty drawback claim using a stale already-superseded rate table, retrospective prior period error correction

Where the correct, updated statutory drawback rate table was already formally published and available at the time each affected claim was made, using a stale, already-superseded table instead is a mistake in applying already-available information - a genuine IAS 8 error, not a change in estimate (which would instead reflect new information not available at the time) - and is corrected retrospectively, recognising the additional drawback receivable and reversing the corresponding overstated expense for each affected prior period, subject to any statutory time limits on actually recovering the additional amount (which would itself factor into the receivable's own recoverability assessment).

144. A garment exporter recognised income from a government RMG export cash incentive scheme on a pure cash-received basis for several prior periods (recognising the incentive only when the cash was actually received from the government, often many months after the qualifying export), even though the scheme's own published rules (available and unambiguous throughout) made clear that the incentive should be recognised as income once the qualifying export shipment and the required documentation were completed and the amount became receivable with reasonable assurance of collection (an accrual-basis approach), materially deferring income recognition relative to the correct period in each case. How should this be corrected upon discovery?

A) No correction is made, since government scheme income is inherently recognised only on receipt regardless of any contrary scheme rules
B) Corrected retrospectively as a material IAS 8 prior period error, restating each affected prior period's export incentive income (and the related receivable) to the period the qualifying export and documentation were completed and collection became reasonably assured, since the scheme's own published rules requiring accrual-basis recognition were already clear and available throughout - this is a mistake applying an already-known basis of recognition, not a legitimate change in accounting policy
C) Corrected by recognising the entire cumulative catch-up amount as a one-off item within other comprehensive income in the current period
D) Corrected prospectively only, switching to accrual-basis recognition from the current period onward, with no restatement of any prior period's income

Correct: B difficult IAS 8/IAS 20 - RMG export cash incentive recognition basis error, retrospective prior period error correction

Where a government incentive scheme's own published rules for income recognition (here, an accrual-basis approach once the qualifying activity is complete and collection is reasonably assured) were already clear and available throughout, applying a pure cash-received basis instead is a mistake in applying an already-known basis, not a legitimate accounting policy choice or a change in estimate; it is corrected retrospectively, restating each affected prior period's export incentive income and the related receivable to the period the qualifying criteria were actually met, in the same way as any other material prior period error.

145. An entity holding a portfolio of cryptocurrency assets measured them, for several prior periods, at cost less impairment under the entity's stated accounting policy of applying the intangible asset cost model, even though the entity's own board-approved accounting policy documentation (in place and unambiguous throughout those periods) actually specified that the intangible asset REVALUATION model (based on an active market price) should be applied instead, given the existence of an active market for the specific cryptocurrency held. How should this be corrected upon discovery?

A) Corrected prospectively only, switching to the revaluation model from the current period's opening balances, with prior periods left unrestated since fair value estimation is inherently judgemental
B) The correction is treated as a voluntary change in accounting policy, requiring only prospective application from the point management decides to adopt the correct model
C) No correction is made, since cryptocurrency assets are entirely outside the scope of any recognised accounting standard and therefore not subject to IAS 8
D) Corrected retrospectively as a material IAS 8 prior period error, restating each affected prior period's carrying amount and revaluation surplus/profit or loss (as the revaluation model would have required) using the actual quoted active-market prices that existed at each relevant date, since the entity's own stated accounting policy already required the revaluation model throughout and applying the cost model instead was a mistake in applying that already-established policy, not a change in policy itself

Correct: D difficult IAS 8/IAS 38 - cryptocurrency measurement model error against the entity's own established policy, retrospective correction

Where the entity's OWN stated accounting policy already specified the revaluation model (given the existence of an active market for the specific cryptocurrency, a policy the entity itself had already established and documented), but the cost model was applied instead in error, this is a mistake in APPLYING an already-established policy - a genuine IAS 8 error - rather than a change in accounting policy (which would require the entity to have genuinely changed its policy going forward, not merely to have failed to apply its existing one); it is corrected retrospectively, restating each affected prior period using the active-market prices that existed at each relevant date, consistent with the policy the entity had already committed to.

146. An entity participating in a voluntary carbon offset programme measured its purchased carbon credits, for several prior periods, at cost with no subsequent remeasurement, even though the entity's own board-approved accounting policy (documented and unambiguous throughout) specified that purchased carbon credits held for potential resale (rather than for the entity's own future compliance use) should be measured at fair value through profit or loss, given their being held principally for trading purposes. How should this be corrected upon discovery that the credits in question were, in fact, always held for resale rather than compliance use?

A) Corrected retrospectively as a material IAS 8 prior period error, restating each affected prior period's carrying amount and the related fair value gains or losses through profit or loss, using the actual market prices for carbon credits that existed at each relevant date, since the entity's own established policy already required fair value measurement for credits held for resale and applying the cost model instead was a mistake applying that already-established policy
B) Corrected prospectively only, remeasuring to fair value from the current period's opening balance, with no restatement of prior periods
C) No correction is made, since carbon credits are considered inherently non-monetary items exempt from any remeasurement requirement
D) The cumulative fair value adjustment is recognised entirely within a separate carbon credit revaluation reserve in equity, bypassing profit or loss for all periods including the current one

Correct: A difficult IAS 8 - carbon credit measurement model error against the entity's own established policy, retrospective correction

Where the entity's own established accounting policy already required fair value through profit or loss measurement for carbon credits held for resale (a classification the credits in question always actually met), but the cost model was mistakenly applied instead, this is a mistake in applying an already-established policy - a genuine IAS 8 error; it is corrected retrospectively, restating each affected prior period's carrying amount and the related fair value gains or losses through profit or loss (since that is where such gains or losses would have been recognised under the policy actually applicable), using the market prices for carbon credits that existed at each relevant date.

147. An Islamic bank's system for calculating and distributing profit to different tiers of Mudaraba depositor accounts (each tier carrying a different pre-agreed weightage in the profit-sharing formula) was found, on investigation, to have applied the WRONG weightage percentage to one specific deposit tier for several prior periods, due to a configuration error when that tier was first set up in the bank's core system (the correct weightage for that tier was clearly and unambiguously documented in the bank's own approved product terms throughout). How should this be corrected upon discovery?

A) No correction is made, since profit distribution weightage errors are regarded as a customer relations matter rather than a financial reporting matter
B) Corrected retrospectively as a material IAS 8 prior period error, restating each affected prior period's profit distribution expense and the related depositor liability using the weightage actually documented in the bank's own approved product terms, since the correct weightage was clearly and unambiguously available from inception and the discrepancy arose purely from a system configuration mistake, not from any genuine ambiguity or a subsequent legitimate change in terms
C) The correction is made only prospectively and only for depositors who have specifically complained about their own profit distribution amount
D) Corrected prospectively only, applying the correct weightage from the current period onward, with the historical shortfall or excess to affected depositors absorbed with no restatement of prior periods

Correct: B difficult IAS 8 - Islamic bank Mudaraba profit distribution weightage configuration error, retrospective prior period error correction

Where the correct profit-sharing weightage for a specific deposit tier was clearly and unambiguously documented in the bank's own approved product terms from the tier's inception, and the discrepancy arose purely from a system configuration error rather than any genuine ambiguity or subsequent legitimate change in terms, this is a straightforward IAS 8 error - a mistake applying already-known, available information - requiring retrospective restatement of each affected prior period's profit distribution expense and the related depositor liability using the weightage actually documented in the approved product terms.

148. An entity discovers that a material deferred tax asset for unused tax losses was NOT recognised for several prior periods, even though sufficient convincing evidence that future taxable profit would be available to utilise those losses (a stable, multi-year history of forecast accuracy and a signed, binding long-term supply contract already in place at each of those prior reporting dates) already existed and was known at each of those dates, but was overlooked by the preparer at the time. How should this omission be corrected upon discovery?

A) No correction is made, since deferred tax assets for unused tax losses can only ever be recognised prospectively under any circumstances
B) The deferred tax asset is recognised retrospectively but the corresponding credit is taken directly to a separate deferred tax reserve within equity rather than through retained earnings or profit or loss
C) Corrected prospectively only, recognising the deferred tax asset for the first time in the current period with the full cumulative effect recognised as current-period income, since deferred tax asset recognition is inherently a matter of current judgement
D) Corrected retrospectively as a material IAS 8 prior period error, recognising the deferred tax asset (and the related deferred tax credit to profit or loss) for each affected prior period in which the convincing evidence already existed and was known but was overlooked, since this is a mistake in applying already-available evidence at the time, distinguished from a genuine change in estimate that would instead reflect newly-emerging evidence not available at the earlier dates

Correct: D difficult IAS 8/IAS 12 - deferred tax asset for unused tax losses omitted despite already-existing evidence, retrospective correction

This scenario mirrors the well-established IAS 8 principle applied elsewhere (for example, to an impairment reversal omitted because supporting evidence already existed and was overlooked at the prior reporting date): where convincing evidence supporting recognition (here, of a deferred tax asset for unused tax losses) already existed and was known at each prior reporting date but was simply overlooked by the preparer, this is a mistake applying already-available evidence - a genuine IAS 8 error - distinguished from a change in estimate reflecting genuinely new evidence emerging later; it is corrected retrospectively, recognising the deferred tax asset and the related credit to profit or loss for each affected prior period in which the evidence already existed.

149. A company undertook a share consolidation (a reverse split, exchanging several existing shares for fewer, higher-nominal-value shares) partway through a prior comparative period; the primary financial statements for that prior period were correctly adjusted for the consolidation, but the comparative earnings per share (EPS) figure for the period BEFORE the consolidation, presented as a comparative in a later set of financial statements, was never actually restated to reflect the consolidation's effect on the weighted average number of shares, an omission discovered only in the current period. How should this be corrected?

A) Corrected retrospectively as a material IAS 8 prior period error, restating the affected comparative EPS figure to reflect the share consolidation as if it had occurred at the very beginning of the earliest period presented, consistent with IAS 33's own specific requirement that a share consolidation be reflected retrospectively in EPS for all periods presented, and treated as a correction since the entity's own comparative figures failed to apply this already-mandatory retrospective adjustment
B) The EPS figure is left uncorrected but a qualitative note is added explaining that a share consolidation occurred during the comparative period
C) No correction is required, since a share consolidation's effect on comparative EPS is considered a voluntary enhancement rather than a mandatory restatement
D) Corrected only for the current period's own EPS calculation, with the comparative figure in the current year's financial statements left exactly as originally (incorrectly) presented

Correct: A difficult IAS 8/IAS 33 - share consolidation retrospective EPS restatement omitted from comparatives, corrected as a prior period error

IAS 33 requires that where the number of ordinary shares changes as a result of a share consolidation (or similar capitalisation-type change) without a corresponding change in resources, the weighted average number of shares used in EPS is adjusted RETROSPECTIVELY for all periods presented, as if the change had occurred at the very beginning of the earliest period presented; failing to apply this already-mandatory retrospective EPS adjustment to a comparative figure is therefore an IAS 8 error (a failure to apply an already-known, mandatory requirement) requiring correction of the comparative EPS figure now that the omission has been discovered.

150. An entity factored (sold) a portfolio of trade receivables to a factor several years ago, derecognising the receivables from its own statement of financial position at the time on the basis that the factoring was without recourse; a review now discovers that the factoring agreement's actual legal terms (available and unambiguous throughout) in fact gave the factor meaningful recourse back to the entity for non-payment by the underlying customers, meaning substantially all the risks and rewards of the receivables had NOT genuinely transferred, and derecognition should never have occurred. How should this be corrected upon discovery?

A) The correction is made only to the current period's closing balance sheet, with the receivables and secured borrowing reinstated at their current balances but no restatement of any prior period's profit or loss for the finance cost that should have been recognised on the secured borrowing
B) Corrected prospectively only, reinstating the receivables and recognising the corresponding secured borrowing liability from the current period's opening balances, with no restatement of the prior periods during which the receivables remained wrongly derecognised
C) Corrected retrospectively as a material IAS 8 prior period error, reinstating the receivables (net of any amounts genuinely collected or written off in the interim) and recognising a secured borrowing liability for the cash advanced by the factor, restating each affected prior period's financial statements, since the agreement's actual recourse terms were already clear and available at the time and the original derecognition assessment was simply wrong in applying them, not a change in circumstances
D) No correction is required, since once a derecognition assessment has been made and applied in a set of published financial statements, it can never subsequently be revisited under any circumstances

Correct: C difficult IAS 8/IFRS 9 - factored receivables wrongly derecognised despite known recourse terms, retrospective correction reinstating secured borrowing

Where the factoring agreement's actual legal recourse terms were already clear and available at the time of the original transaction, and the original assessment simply misapplied those known terms (concluding no recourse when meaningful recourse in fact existed, meaning substantially all risks and rewards had not genuinely transferred), this is a mistake applying already-available information - a genuine IAS 8 error, not a change in circumstances; it is corrected retrospectively, reinstating the receivables and recognising a secured borrowing liability (with the associated finance cost restated through profit or loss for each affected period) as if the correct with-recourse assessment had been applied from the outset.
