76. Longstone Manufacturing plc discovers that a material deferred tax temporary difference was measured in the prior year using a superseded tax rate, when a new tax rate had, in fact, already been substantively enacted before the prior year's financial statements were authorised for issue. How should this be treated, and how would the answer differ if the new rate had instead been enacted only after the prior year's financial statements were authorised for issue?

A) It is never appropriate to use a rate other than the rate in force at the actual balance sheet date, so no restatement question can arise in either scenario
B) It is a prior period error requiring restatement, since the correct (substantively enacted) rate was already available before authorisation for issue and simply was not applied; had the new rate instead been enacted only after authorisation for issue, it would affect only the current or future period, with no restatement of the prior year required
C) It is a change in accounting estimate in both scenarios described, applied prospectively, since deferred tax rates are inherently subject to legislative change
D) It is a prior period error requiring restatement in both scenarios described, regardless of when the new rate was actually enacted relative to authorisation for issue

Correct: B difficult IAS 12 Income Taxes, paragraph 47; IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors, paragraph 5

Deferred tax is measured using tax rates that have been enacted or substantively enacted by the reporting date; if a new rate had, in fact, already been substantively enacted before the prior year's financial statements were authorised for issue, using the old, superseded rate instead was a mistake in applying information (the substantively enacted rate change) that was already available at the time, meeting the definition of a prior period error requiring retrospective restatement. Had the new rate instead only been enacted after the prior year's financial statements were authorised for issue, no error would exist for that prior period, since the old rate was genuinely the correct rate to use at that time; the new rate would then affect only the current period's (or a future period's) measurement, applied prospectively as a change in estimate reflecting new information. Option D fails to distinguish between the two scenarios. Option C incorrectly treats even the error scenario as a mere estimate change. Option A incorrectly denies that substantive enactment (short of final legal enactment) is the relevant test under IAS 12.

77. Underbank Financial Services Ltd reclassified a portfolio of debt investments from amortised cost to fair value through profit or loss in the prior year, asserting a change in business model. This year, it becomes clear that no genuine change in business model actually occurred; management's original assertion was mistaken. How should this be corrected?

A) The reclassification is reversed only prospectively from the date the mistake is identified, with the fair value through profit or loss measurement retained for the intervening period already reported
B) No correction is required, since the portfolio's fair value and amortised cost measurements would converge over time regardless of which classification is used
C) The reclassification is reversed as a prior period error, restoring the portfolio to amortised cost measurement as if the reclassification had never occurred, since IFRS 9 reclassifications must reflect a genuine change in business model, which did not, in fact, happen
D) The reclassification stands as originally made, since IFRS 9 reclassifications, once made, are never subsequently reversible under any circumstances

Correct: C difficult IFRS 9 Financial Instruments, paragraphs 4.4.1-4.4.3; IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors, paragraph 5

IFRS 9 permits reclassification of financial assets only when an entity genuinely changes its business model for managing those assets, and such changes are expected to be rare. Where it becomes clear that no genuine change in business model actually occurred, and the original reclassification was based on a mistaken assertion, the reclassification itself was never validly made in the first place; correcting this is a prior period error, requiring the reclassification to be reversed retrospectively, restoring the portfolio to amortised cost measurement as if the (invalid) reclassification had never occurred, rather than treating the reversal as a fresh, separate reclassification event. Option D incorrectly treats even an invalid, mistaken reclassification as permanently binding. Option A wrongly limits the correction to a prospective reversal, leaving the already-reported fair value through profit or loss figures for the intervening period uncorrected, when they, too, were based on an invalid reclassification. Option B wrongly dismisses the need for correction based on an unrelated argument about eventual value convergence, which does not address the measurement and presentation differences that existed during the intervening periods.

78. A company originally classified an intangible asset as having a finite useful life of 10 years. Following a change in the market and competitive environment, management now reasonably assesses that there is no foreseeable limit to the period over which the asset is expected to generate net cash inflows, and reclassifies it as having an indefinite useful life. How is this reclassification treated?

A) As a change in accounting estimate, applied prospectively: amortisation ceases from the date of the reassessment onward (with the asset instead tested annually for impairment), and no restatement of previously recognised amortisation charged in prior periods is required, since the original estimate reflected the information reasonably available at the time and the change reflects new information about future cash flow patterns, not a mistake
B) The reclassification cannot be made at all once an intangible asset has initially been classified as finite-lived
C) As a prior period error requiring retrospective restatement, since the original 10-year estimate has turned out to be incorrect
D) As a voluntary change in accounting policy, requiring full retrospective application to all prior periods presented

Correct: A complex IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors, paragraphs 32-38; IAS 38 Intangible Assets (useful life reassessment)

A change in the assessed useful life of an asset, including a change from finite to indefinite (or vice versa) based on new information about the expected pattern of future economic benefits, is a change in accounting estimate under IAS 8, applied prospectively. This is distinguished from an error, since the original estimate was reasonable based on information available at the time; no restatement of prior periods is required.

79. A newly incorporated entity, in preparing its very first set of financial statements (with no prior period comparatives, since none exist), discovers during that first year that an error was made in recording a transaction earlier within that same first year, before the trial balance was finalised. How should this be corrected?

A) The error must be disclosed as a qualification in the auditor's report with no correcting entry made in the accounting records
B) As a prior period error under IAS 8, requiring adjustment to opening retained earnings and restatement of comparative figures
C) The entity cannot correct the error at all in its first year and must wait until its second year to make any adjustment
D) Simply as a current-period correcting entry within the same first year's own records, since there is no prior period or comparative financial statements to restate; IAS 8's prior period error provisions are not engaged when the error and its correction both occur within the entity's very first reporting period, before any financial statements have yet been issued

Correct: D complex IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors, paragraph 5 (definition of prior period errors)

IAS 8's prior period error provisions (restating opening retained earnings and comparatives) are engaged only where an error relates to one or more prior periods for which financial statements have already been issued. Where the error occurs and is discovered within an entity's very first reporting period, before any financial statements exist, it is simply corrected as an ordinary current-period correcting entry in the underlying records, with no restatement mechanism required since there is no prior period to restate.

80. A material error is discovered relating to the prior year's measurement of a cash flow hedge, which resulted in an incorrect amount being recognised within the cash flow hedge reserve (a component of other comprehensive income) rather than in retained earnings directly. How should the correction of this error be reflected in the restated opening equity balances?

A) No restatement of equity is required, since amounts within other comprehensive income reserves are outside the scope of IAS 8's prior period error requirements
B) The correction is always made to opening retained earnings, regardless of which original equity component the error actually affected
C) The correction is spread proportionately across all equity reserves regardless of which one the original error affected
D) The correction is made to the specific equity component that was originally affected by the error - here, the cash flow hedge reserve - restating that reserve's opening balance, rather than automatically defaulting the correction to retained earnings, since the restatement should reflect where the error actually originated within equity

Correct: D complex IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors, paragraphs 42-49

IAS 8's retrospective restatement principle requires correcting the specific line item(s) that were originally affected by the error, restating the opening balance of that item for the earliest period presented. Where the error relates to a component of other comprehensive income (such as a cash flow hedge reserve) rather than a profit-or-loss item, restatement is made to that specific reserve, not automatically defaulted to retained earnings.

81. After a subsidiary's discontinued operation is fully disposed of and its results presented separately in the prior year's financial statements, a material error is discovered relating to the measurement of that discontinued operation's results in the year prior to disposal. How should this error be corrected?

A) The error is corrected only within the current period's continuing operations line, with no restatement of the discontinued operations comparative
B) The error is treated as an adjustment to goodwill on disposal rather than as a prior period error
C) The error is corrected under IAS 8 in the ordinary way, restating the affected prior period's results, including the specific discontinued operations line item(s) within the comparative income statement that were originally misstated, since the disposal of the underlying business does not remove the requirement to correct a material error in previously reported figures relating to it
D) The error cannot be corrected at all once the operation has been fully disposed of and is no longer part of the group

Correct: C complex IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors, paragraphs 42-49; IFRS 5 (discontinued operations presentation)

The disposal of the business to which an error relates does not exempt the error from IAS 8's ordinary retrospective restatement requirements. A material error relating to a discontinued operation's results in a prior period is corrected by restating the comparative discontinued operations line item(s) in the same way as any other material prior period error, ensuring previously reported figures faithfully represent what should have been reported.

82. A company corrects a material prior period error in its financial statements. Separately, this same error also means an earlier VAT return submitted to the tax authority was incorrect, requiring an amended VAT return to be filed. How should these two consequences of the same underlying error be distinguished?

A) They are the same single correction; filing the amended VAT return automatically satisfies the IAS 8 financial reporting correction requirement with no further action needed
B) Only the financial statement restatement is required; no amended VAT return is ever necessary once the accounting records are corrected
C) Only the amended VAT return needs to be filed; no financial statement restatement is required if the tax authority accepts the amendment
D) The IAS 8 financial reporting correction (retrospective restatement of the financial statements) and the separate regulatory obligation to file an amended VAT return with the tax authority are two distinct consequences of the same underlying error, each governed by its own separate framework (accounting standards versus tax administration law), and both must be addressed independently, though the corrected VAT position feeds into the financial statement correction (e.g. adjusting the VAT liability/receivable)

Correct: D complex IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors; general tax administration principles (context)

A single underlying error can trigger both an accounting correction (governed by IAS 8, requiring retrospective restatement of the financial statements) and a separate regulatory filing obligation (an amended VAT return, governed by tax administration rules), which are distinct requirements under different frameworks. Both must be addressed, and the corrected tax position (e.g. VAT liability or receivable) should be reflected consistently within the restated financial statements themselves.

83. A cumulative multi-year error is discovered, but the earliest affected period falls outside the entity's statutory record-retention period, and the original supporting documentation for that earliest period can no longer be located or reconstructed with any reliability. How should the entity proceed under IAS 8's impracticability provisions?

A) The entity must restate all periods back to incorporation, using zero as a default value for any period with missing records
B) Where it is impracticable to determine the period-specific effects of the error on the earliest period(s) affected (here, because the underlying records genuinely no longer exist or cannot be reliably reconstructed), IAS 8 permits the entity to restate the opening balances of assets, liabilities, and equity for the earliest period for which restatement IS practicable (which may be a later period than the error's true origin), rather than requiring restatement of a period for which reliable figures cannot be determined
C) The entity must estimate the earliest period's figures using pure guesswork with no basis in evidence, since IAS 8 requires restatement of every period regardless of practicability
D) The entity simply ignores the error entirely, since the earliest period's records are unavailable

Correct: B complex IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors, paragraphs 43-45, 50

IAS 8's impracticability exception specifically addresses situations where determining the period-specific effects of an error on one or more prior periods is not practicable, such as where necessary information is genuinely unavailable and cannot be reliably reconstructed. In such cases, the entity restates from the earliest period for which restatement is practicable, rather than attempting an unreliable estimate for a period whose records no longer exist, or ignoring the error altogether.

84. A listed company discovers and corrects a material prior period error under IAS 8. Separately, as a listed entity, it is also subject to continuing disclosure obligations under securities/listing regulations that may require an immediate market announcement of price-sensitive information. How do these two requirements interact?

A) Continuing disclosure obligations only ever apply to new information about future events, never to corrections of past reported information
B) The two requirements are separate and both potentially apply: the IAS 8 restatement addresses the financial reporting correction, while the securities/listing regulator's continuing disclosure obligations (which may require a timely market announcement if the error correction constitutes material, price-sensitive information) are a distinct, additional regulatory requirement operating alongside the accounting standard, not a substitute for it
C) Only the IAS 8 financial statement restatement is required; listing rule disclosure obligations never apply to accounting error corrections
D) The listing rule market announcement automatically satisfies the IAS 8 restatement requirement, with no separate financial statement correction needed

Correct: B complex IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors; general securities/listing regulation principles (context)

IAS 8 governs how a prior period error is corrected within the financial statements themselves. Separately, securities/listing regulations impose continuing disclosure obligations requiring timely market announcements of material, price-sensitive information, which can be triggered by the discovery of a material error even before the next financial statements are issued. These are distinct, cumulative requirements operating under different frameworks, both potentially engaged by the same discovered error.

85. A business combination's contingent consideration liability was measured using a probability assumption that, with hindsight, proves to have been based on facts that existed but were not yet known to management at the acquisition date (a genuine measurement period adjustment scenario), but this is only identified 15 months after the acquisition date, after the 12-month IFRS 3 measurement period has already closed. How should this be corrected?

A) Since the correction is identified after the IFRS 3 measurement period (a maximum of 12 months from the acquisition date) has already closed, it can no longer be treated as a measurement period adjustment; instead, it is corrected as an IAS 8 prior period error (if the original measurement reflected a mistake in applying information that was available, or should have been available, at the acquisition date) or as a change in estimate (if based on genuinely new information arising after the measurement period), with the correction recognised in profit or loss rather than adjusted against goodwill
B) The correction is made by reopening and extending the measurement period itself for this specific asset only
C) No correction of any kind is possible once the measurement period has closed, regardless of the reason for the error
D) As an ordinary IFRS 3 measurement period adjustment, retrospectively adjusting goodwill, regardless of when it is identified relative to the measurement period

Correct: A complex IFRS 3 Business Combinations, paragraphs 45-50 (measurement period); IAS 8 (error correction after measurement period closes)

IFRS 3's measurement period adjustment mechanism (retrospective adjustment against goodwill) is only available within the 12-month measurement period. Once that window has closed, a subsequently identified issue with the original acquisition accounting is instead addressed either as an IAS 8 prior period error (correcting a mistake in applying facts and circumstances that existed at the acquisition date) or as a change in accounting estimate (if driven by genuinely new information), with the correction recognised in profit or loss going forward or restated per IAS 8, rather than through the closed measurement period mechanism.

86. An investor accounts for its interest in a joint venture using the equity method. A material error is subsequently discovered in the joint venture's own previously reported results (the joint venture itself, not the investor, made the original error), affecting the investor's previously recognised share of the joint venture's profit. How should the investor reflect this in its own financial statements?

A) The investor discontinues use of the equity method entirely and switches to the cost method as a consequence of the joint venture's error
B) The investor restates its own comparative share of the joint venture's profit or loss (and the corresponding carrying amount of its investment) to reflect the corrected amounts, treating this as a prior period error in its own financial statements under IAS 8, even though the error originated within the joint venture's own separately prepared financial statements, since the investor's previously reported share of profit was itself consequently misstated
C) The investor makes no adjustment at all, since the error originated in the joint venture's own separate financial statements, not the investor's records
D) The investor's auditors alone are responsible for correcting the joint venture's error, with no effect on the investor's own financial statements

Correct: B complex IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors; IAS 28 Investments in Associates and Joint Ventures (equity method)

Although the error originated in the joint venture's own separately prepared financial statements, its effect flows through to the investor's own previously recognised share of profit and investment carrying amount under the equity method. The investor must correct its own financial statements to reflect the corrected share, treating this as a prior period error in its own right under IAS 8, since its own previously reported figures were consequently misstated.

87. Two errors are individually assessed and each found to be immaterial to the financial statements taken as a whole. However, both errors arise from the same underlying systemic cause (a misconfigured setting in a shared accounting system module affecting two different expense categories), and their combined, aggregated financial effect IS material. How should these two errors be treated?

A) Because the two errors share a common underlying cause and their combined effect is material, they should be aggregated and corrected together as a single material prior period error requiring retrospective restatement, rather than being assessed and dismissed in isolation from one another, since materiality is assessed based on the aggregate effect of related misstatements, not merely each one considered separately
B) Each error is corrected individually as a current-period adjustment with no restatement, since each one considered alone is immaterial
C) Only the larger of the two errors is corrected, with the smaller one permanently ignored
D) The two errors are never aggregated for materiality purposes under any circumstances, since they affect different expense categories

Correct: A complex IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors, paragraph 5 (materiality); IAS 1 (materiality, aggregation)

Materiality assessment requires consideration of the aggregate effect of individually immaterial errors that share a common cause or are otherwise related, since assessing each in isolation could allow a collectively material misstatement to go uncorrected. Where the combined effect of related errors is material, they should be corrected together as a single material prior period error under IAS 8, requiring retrospective restatement.

88. A financial instrument was incorrectly designated at initial recognition as measured at amortised cost when, based on the entity's actual business model and the instrument's contractual cash flow characteristics at that date, it should have been classified and measured at fair value through profit or loss (FVTPL). This misclassification is discovered two years later. How is the correction made?

A) Since the original classification was a mistake in applying the IFRS 9 classification criteria to facts and circumstances that existed at initial recognition (not a genuine subsequent business model change, which is the only basis for a prospective IFRS 9 reclassification), this is a prior period error under IAS 8, requiring retrospective restatement: the instrument's carrying amount is restated to what it would have been at FVTPL throughout, with corresponding restatement of all fair value movements that should have been recognised in profit or loss in each affected prior period
B) No correction is possible once two years have passed since the original classification was made
C) The instrument is simply reclassified to FVTPL prospectively from the date of discovery, with no adjustment to prior periods, since IFRS 9 reclassifications are always applied prospectively
D) The correction is made only to the current year's profit or loss, with the cumulative catch-up adjustment treated as a change in accounting estimate

Correct: A complex IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors; IFRS 9 Financial Instruments, paragraphs 4.4.1-4.4.3 (reclassification)

IFRS 9 permits reclassification of financial assets prospectively only following a genuine change in the entity's business model. An original misclassification that resulted from misapplying the classification criteria to the facts and circumstances that existed at initial recognition is a mistake, not a business model change, and is therefore corrected as an IAS 8 prior period error, requiring full retrospective restatement of the instrument's measurement basis and all consequential fair value movements in each affected period.

89. A prior year's business combination was originally accounted for as giving rise to a bargain purchase gain. On subsequent review, a material error is identified in the original acquisition accounting (an intangible asset that should have been separately recognised was omitted), and correcting this error converts the original bargain purchase gain into positive goodwill instead. How should this be addressed?

A) The correction is treated as a change in accounting estimate, applied prospectively with no impact on previously reported figures
B) The entire acquisition accounting is reworked to correct the error (recognising the omitted intangible asset at its correct fair value at the acquisition date), which converts the original bargain purchase gain into positive goodwill; this is corrected as a material IAS 8 prior period error (given the error relates to a mistake in applying the acquisition accounting requirements to facts existing at the acquisition date, discovered after the measurement period closed), and the resulting goodwill must then be tested for impairment from the acquisition date forward as part of the correction
C) No correction is made, since a bargain purchase gain, once recognised, can never subsequently be reversed under any circumstances
D) Only the current year's financial statements are adjusted for the newly recognised goodwill, with no restatement of the original bargain purchase gain in the comparative period

Correct: B complex IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors; IFRS 3 Business Combinations (bargain purchase, goodwill)

An error in the original acquisition accounting that results in a previously recognised bargain purchase gain actually being incorrect (because an asset was omitted, meaning the transaction was not in fact a bargain purchase) requires the entire acquisition accounting to be reworked and corrected as a material IAS 8 prior period error, converting the gain into goodwill; since goodwill is subject to mandatory annual impairment testing rather than amortisation, the newly recognised goodwill must then be tested for impairment as part of the correction, and the affected comparative periods restated.

90. A material forward-looking expected credit loss (ECL) overlay, based on economic information already evident and known at the prior year end (such as a clearly deteriorating industry sector already publicly reported at that date), was omitted from the prior year's ECL calculation. This omission is discovered in the current year. How should this be distinguished from a genuine subsequent change in estimate?

A) It can only be corrected by adjusting the following year's ECL charge, with no restatement of the prior year permitted
B) It is always treated as an immaterial timing difference requiring no correction of any kind
C) Since the relevant forward-looking information was already evident and reasonably available at the prior reporting date, its omission from the original ECL calculation reflects a mistake in applying information that should have been incorporated at that time, making this a prior period error requiring retrospective restatement of the prior year's ECL allowance, rather than a change in estimate, which would instead apply where genuinely new information not available at the prior date has since emerged
D) It is always treated as a change in estimate, since ECL calculations inherently involve forward-looking judgement

Correct: C complex IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors, paragraph 5; IFRS 9 Financial Instruments (expected credit losses)

The key distinction between an error and a change in estimate is whether the information was available (or should reasonably have been available) at the original reporting date. Since the deteriorating industry conditions were already evident and known at the prior year end, failing to incorporate them into the ECL calculation was a mistake in applying available information, constituting a prior period error requiring retrospective restatement, not a change in estimate reflecting new information.

91. A deferred tax rate error is discovered: the prior year's deferred tax balances were measured using an outdated tax rate, when a new, lower tax rate had already been substantively enacted before the prior year's financial statements were authorised for issue. How should this be corrected, compared with a scenario where the rate change is enacted only after authorisation for issue?

A) Both scenarios are treated identically, as changes affecting only the current and future periods, with no restatement of the prior year in either case
B) Neither scenario ever requires any adjustment, since deferred tax rates are inherently estimates not subject to error correction
C) Since the lower rate was already substantively enacted before the prior year's financial statements were authorised for issue, using the outdated rate was a mistake in applying information that existed and should have been used at that time; this is a prior period error requiring retrospective restatement of the prior year's deferred tax balances. By contrast, a rate enacted only after authorisation for issue for that period would not have been available at the relevant date, and its effect would instead be reflected only in the current or future period once enacted, not restated into the prior period
D) Both scenarios always require the tax authority's own written confirmation before any correction can be made

Correct: C complex IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors; IAS 12 Income Taxes, paragraph 47 (substantively enacted rates)

The critical distinguishing factor is whether the rate was substantively enacted before or after the relevant financial statements were authorised for issue. A rate already substantively enacted beforehand should have been used in measuring deferred tax at that reporting date, so using an outdated rate is a mistake (prior period error) requiring retrospective restatement. A rate enacted only afterward could not have been reflected at that date and instead affects only the current/future period from the point of enactment.

92. A parent company holds its investment in a wholly-owned subsidiary at cost in its own separate (unconsolidated) financial statements, as permitted under IAS 27. A material prior period error is discovered and corrected within the subsidiary's own financial statements, restating the subsidiary's opening retained earnings. What effect, if any, does this have on the parent's own separate financial statements' carrying amount for its investment in the subsidiary?

A) The parent's investment in subsidiary carrying amount must be restated by the same amount as the subsidiary's retained earnings restatement, since the two are directly linked
B) No correction of any kind is required anywhere in the group once the subsidiary's own standalone financial statements have been restated
C) The parent must switch from the cost model to the equity method in its separate financial statements as a direct consequence of the subsidiary's error correction
D) Where the investment is held at cost in the parent's separate financial statements, the subsidiary's own retained earnings restatement does not, by itself, change the parent's cost-based investment carrying amount, since cost is unaffected by the investee's subsequent results or their restatement; however, the parent should still consider whether the underlying error indicates an impairment indicator requiring a separate impairment assessment of the investment, and the error would need correcting in the CONSOLIDATED financial statements

Correct: D complex IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors; IAS 27 Separate Financial Statements, paragraph 10 (cost model); IAS 36 (impairment indicators)

Under the cost model permitted by IAS 27 for a parent's separate financial statements, the investment in a subsidiary is carried at cost (adjusted only for impairment), which is not automatically affected by a restatement of the subsidiary's own retained earnings. The subsidiary's error correction does, however, flow through fully into the consolidated financial statements (where the subsidiary's results are consolidated), and separately warrants consideration of whether the underlying error is an indicator that the parent's cost-based investment carrying amount may now be impaired.

93. An entity has, for several years, measured a class of its owned buildings using the cost model under IAS 16. This year, it decides to change to the revaluation model for that same class of buildings, a change explicitly permitted by IAS 16 as an accounting policy choice. How should this change from the cost model to the revaluation model be applied, and how does this differ from the general IAS 8 requirement for a voluntary change in accounting policy?

A) The change is prohibited entirely once an entity has selected the cost model for a class of assets, regardless of any later policy reconsideration
B) It is applied retrospectively, exactly like any other voluntary change in accounting policy under IAS 8's general default rule, restating all prior comparative periods as if the revaluation model had always been used
C) The change can only be made if it is treated as a correction of a prior period error, requiring the cost model to be shown as having been wrong all along
D) IAS 16 specifically requires a change from the cost model to the revaluation model to be applied prospectively from the date of the revaluation itself (the asset is simply revalued to fair value at that date, with the resulting surplus or deficit recognised under IAS 16's own revaluation rules), rather than following IAS 8's general default requirement of full retrospective restatement that would otherwise apply to a voluntary policy change, since a retrospective revaluation as at earlier dates is neither required nor generally practicable in the same way

Correct: D complex IAS 16 / IAS 8 - prospective application exception for a cost-to-revaluation model policy change

While IAS 8 generally requires a voluntary change in accounting policy to be applied retrospectively, IAS 16 itself specifically addresses the cost-to-revaluation model transition: the change is treated as a revaluation under IAS 16 and applied prospectively, with the asset revalued to its fair value at the date of the change and any resulting surplus or deficit accounted for under IAS 16's normal revaluation rules, rather than requiring retrospective restatement of prior comparative periods, illustrating a specific standard-level exception to IAS 8's general retrospective default for policy changes.

94. An entity's functional currency genuinely changes partway through the year, because there has been a real, underlying shift in the primary economic environment in which the entity operates (for example, its sales and financing activities have genuinely shifted to be predominantly denominated in, and influenced by, a different currency). How should this genuine change in functional currency be applied, and how does this differ from discovering that the entity's ORIGINAL functional currency determination, made in an earlier period, was simply wrong given the facts that existed at that time?

A) Both situations are corrected only prospectively, with no distinction drawn between a genuine change in circumstances and an original determination error
B) Both situations are treated identically, as prior period errors under IAS 8 requiring full retrospective restatement of all previously reported figures
C) A genuine change in functional currency, reflecting an actual underlying change in economic circumstances, is applied prospectively from the date of the change (translation procedures for the new functional currency apply from that date forward, with no restatement of amounts already properly reported under the old functional currency), whereas discovering that the ORIGINAL functional currency determination was simply wrong at the time it was made (given the facts and circumstances that actually existed then) is a prior period error under IAS 8, requiring retrospective restatement
D) A genuine change in functional currency can never occur under any circumstances; only original determination errors are ever possible

Correct: C complex IAS 21 / IAS 8 - genuine functional currency change (prospective) distinguished from an original determination error (retrospective)

IAS 21 treats a genuine change in an entity's functional currency, arising from an actual change in the underlying economic circumstances the currency indicators assess, as a change applied prospectively from the date of that change, since the entity's functional currency genuinely was different before and after the shift. This is fundamentally different from discovering that the original functional currency determination was simply incorrect based on the facts and circumstances that existed at the time it was made; that is a mistake in applying already-available information and constitutes a prior period error under IAS 8, requiring retrospective restatement.

95. An entity discovers that, in translating a foreign subsidiary's prior period results for consolidation, the wrong AVERAGE exchange rate was used to translate the subsidiary's income statement for that period (as opposed to an error in the CLOSING rate used to translate its statement of financial position net assets). How does correcting this average-rate translation error differ in effect from correcting a wrong closing-rate error?

A) An error in the average rate used to translate the income statement primarily restates the subsidiary's translated PROFIT for the prior period (affecting the comparative income statement and retained earnings), whereas an error in the closing rate used to translate the statement of financial position net assets primarily restates the translation reserve within other comprehensive income/equity (with a corresponding balancing adjustment in the translation reserve to reconcile net assets), reflecting that each rate error originally affected a different component of the consolidated financial statements
B) There is no difference at all; both types of rate error affect only the foreign currency translation reserve within other comprehensive income/equity, with no effect on reported profit
C) An average rate error can never be corrected under IAS 8, since average rates are inherently estimates rather than an error-prone figure
D) Both types of rate error can only ever be corrected by restating the parent's own separate (unconsolidated) financial statements, never the consolidated figures

Correct: A complex IAS 8 / IAS 21 - correcting an average-rate translation error (profit) versus a closing-rate translation error (translation reserve)

The average rate is used to translate a foreign subsidiary's income statement, so an error there is corrected by restating the translated profit for the affected prior period, flowing through retained earnings on restatement, whereas the closing rate is used to translate the subsidiary's statement of financial position net assets, so an error there is corrected primarily within the translation reserve in other comprehensive income/equity. Each type of rate error is corrected in the specific component of the consolidated financial statements where it originally arose, illustrating that a foreign currency translation error's correction depends on which specific rate (average or closing) was actually misapplied.

96. An entity enters into a genuinely novel transaction type for which no specific IFRS standard directly applies. In selecting an appropriate accounting policy, management first looks to the requirements of other IFRSs dealing with similar and related issues, and, failing that, to the definitions, recognition criteria, and measurement concepts in the Conceptual Framework, exercising its own judgement as IAS 8 requires. In a later period, following a new authoritative pronouncement that becomes directly applicable, management changes its treatment of this transaction type accordingly. How should this later change be characterised?

A) The later change is always a change in accounting estimate, since judgement was originally involved in selecting the policy
B) It is always treated as a correction of a prior period error, since the original judgement-based policy is retrospectively deemed to have been wrong
C) No change of any kind is permitted once an accounting policy has been selected using the IAS 8 hierarchy, regardless of any later authoritative pronouncement
D) Where the original policy was a reasonable exercise of judgement based on the information, standards, and Conceptual Framework guidance available at the time (applying IAS 8's own hierarchy for selecting a policy absent a specific standard), and the later change results from a new authoritative pronouncement becoming applicable (rather than a mistake in applying the framework that was available at the time), the later change is a change in accounting policy (generally following the transitional provisions of the new pronouncement, or IAS 8's general retrospective policy-change rule absent specific transitional guidance), not a correction of an error

Correct: D complex IAS 8 - policy selection hierarchy for novel transactions, later change from a new pronouncement as a policy change not an error

IAS 8 explicitly permits management to exercise judgement in developing an accounting policy where no standard specifically applies, using the described hierarchy (other IFRSs on similar issues, then the Conceptual Framework). A later change prompted by a new authoritative pronouncement becoming directly applicable is a change in accounting policy, not a correction of an error, provided the original judgement was reasonably made based on what was actually available and known at the time; this is distinguished from an error, which would instead reflect a mistake in applying information or standards that were already available when the original judgement was made.

97. In accounting for a prior year business combination, a contingent consideration liability was initially measured using a discount rate that was, at the time, simply calculated incorrectly (a genuine mathematical/input error in applying the entity's own chosen valuation methodology, using data that was fully available at the acquisition date). This is discovered only in a later period, after the measurement period has closed. How should this be corrected, and how does it differ from an ordinary subsequent remeasurement of contingent consideration through profit or loss?

A) It is corrected in exactly the same way as an ordinary subsequent fair value remeasurement of contingent consideration, recognised prospectively in the current period's profit or loss
B) No correction of any kind is required once the measurement period under IFRS 3 has closed, regardless of whether the original error is discovered
C) Because this is a genuine error in the ORIGINAL acquisition-date measurement (using an incorrect discount rate applied to information that was fully available at the time), rather than a change in circumstances or new information arising after the acquisition date, it is corrected as a prior period error under IAS 8, requiring retrospective restatement of the original acquisition accounting (and all consequential effects, such as goodwill and subsequent periods' finance costs), distinguished from an ordinary subsequent remeasurement of contingent consideration (reflecting genuine changes in circumstances after acquisition), which is recognised in profit or loss prospectively as it arises
D) The error must be corrected by adjusting only the current period's finance cost, with no restatement of the original acquisition accounting or goodwill

Correct: C complex IAS 8 / IFRS 3 - original acquisition-date measurement error corrected retrospectively, distinguished from subsequent remeasurement

A mistake in calculating the original acquisition-date discount rate, using information that was fully available at the time, is a genuine measurement error in the original acquisition accounting, not a subsequent change in circumstances. Once discovered after the measurement period has closed, it is corrected as a prior period error under IAS 8, requiring retrospective restatement of the original acquisition accounting and all consequential effects (such as the resulting goodwill figure and cumulative finance costs recognised in subsequent periods), which is a fundamentally different correction mechanism from an ordinary subsequent remeasurement of contingent consideration reflecting genuine post-acquisition developments, recognised prospectively in profit or loss.

98. An entity discovers that a prior year's IFRS 2 share-based payment expense was calculated using the wrong estimate of the number of instruments expected to vest, because the person preparing the calculation made a data entry error, incorrectly transcribing the actual historical employee headcount figures that were fully available at the time, rather than the estimate reflecting any genuine change in expectations about future forfeitures. How should this be characterised and corrected?

A) As a prior period error under IAS 8, since the original estimate was based on a data transcription mistake applied to information that was already fully available and correctly obtainable at the time, rather than reflecting new information or a genuine change in circumstances regarding expected forfeitures; this requires retrospective restatement of the prior period's IFRS 2 expense, distinguished from an ordinary revision of the vesting estimate based on updated expectations, which would be a change in estimate applied prospectively
B) As a change in accounting estimate, applied prospectively over the remaining vesting period with no restatement of the prior period's reported expense
C) It is treated as a change in accounting policy, requiring disclosure of the reason for the policy change
D) The error can never be corrected once the original vesting period has begun, regardless of when the mistake is identified

Correct: A complex IAS 8 / IFRS 2 - data transcription error in a vesting estimate corrected retrospectively, distinguished from an ordinary estimate revision

The key distinction between an IAS 8 error and a change in accounting estimate is whether the original figure was wrong given the facts and circumstances that existed and were available at the time (an error), or whether new information or a change in circumstances has since emerged that alters a previously reasonable estimate (a change in estimate). A data transcription mistake, using headcount data that was fully and correctly available at the time but simply entered incorrectly, is a genuine error rather than a change in estimate, requiring retrospective restatement of the prior period's IFRS 2 expense under IAS 8, in contrast to an ordinary revision of the vesting estimate based on updated future expectations.

99. An entity discovers that a leasehold property was, several years ago, wrongly classified as an operating lease under the old IAS 17 rules (based on the lease terms actually in place at the time, this classification was simply incorrect even under IAS 17's own criteria), meaning the associated finance lease asset and liability were never recognised in those earlier periods. This error is only discovered now, well after the entity has already fully transitioned to IFRS 16 (under which all leases are now recognised on-balance-sheet in any event, making the old classification distinction irrelevant going forward). How should this legacy pre-transition classification error now be corrected?

A) The error is automatically and fully corrected by the IFRS 16 transition itself, requiring no separate IAS 8 restatement of any kind for the earlier misstated periods
B) No correction is needed at all, since the entity has already transitioned to IFRS 16, under which the lease is now recognised on-balance-sheet regardless of its old classification
C) The error still requires correction as an IAS 8 prior period error for the periods it actually affected (the years under the old IAS 17 regime when the lease was incorrectly kept off-balance-sheet), since those specific prior periods' reported figures were genuinely misstated at the time, even though the distinction has since become moot for current and future periods following the IFRS 16 transition; the correction requires reconstructing what the finance lease asset, liability, depreciation, and interest would have been across the affected legacy periods
D) The error can only be corrected as a change in accounting estimate, applied prospectively from the date of the IFRS 16 transition

Correct: C complex IAS 8 / IAS 17 - legacy lease classification error requiring retrospective correction despite the entity's subsequent IFRS 16 transition

The fact that a distinction has since become irrelevant under a new standard does not erase the fact that specific prior periods' reported figures were genuinely misstated at the time, under the rules that actually applied then. A legacy classification error under the old IAS 17 rules, discovered after the entity has already moved to IFRS 16, still requires correction as an IAS 8 prior period error for the specific historical periods it affected, reconstructing the finance lease asset, liability, and related depreciation and interest that should have been recognised under IAS 17 during those periods, rather than being treated as automatically resolved or irrelevant simply because the entity has since transitioned to a new leasing standard.

100. An entity's financial statements present operating expenses by function (cost of sales, administrative expenses, distribution costs). It is discovered that a particular ongoing cost, correctly totalled and included somewhere within the financial statements, was originally allocated to 'administrative expenses' when, based on the actual nature of the activity it relates to, it should properly have been allocated to 'cost of sales' instead; both classifications would have been defensible interpretations of genuinely ambiguous underlying facts at the time, with reasonable accountants potentially differing on the allocation. Is this a prior period error requiring restatement?

A) This can only ever be corrected as a change in accounting policy, since it involves a choice between two acceptable presentation categories
B) Yes, any reclassification between functional expense categories is always automatically treated as a prior period error requiring restatement, regardless of how the original classification was arrived at
C) Where the original functional classification represented a genuinely defensible, reasonable judgement call on ambiguous facts (rather than a factually incorrect application of the entity's own classification policy or the relevant facts), it is not a prior period error at all; only where the original classification can be shown to have been factually wrong (misapplying the actual nature of the cost, or the entity's own established classification policy, based on facts that were available at the time) does IAS 8's error correction and restatement requirement apply
D) The distinction between cost of sales and administrative expenses is never material and can never itself trigger an IAS 8 error correction under any circumstances

Correct: C complex IAS 8 - functional expense reclassification, error requires a factually wrong original classification, not merely a differing judgement call

Not every difference of view on a functional expense classification is a prior period error. Where the original classification reflected a genuinely defensible, reasonable judgement applied to facts that were themselves ambiguous at the time, with reasonable accountants potentially differing, no error exists at all, and reclassifying it now (if done purely as a matter of preference) would not be an IAS 8 restatement. IAS 8's error correction and restatement requirement is reserved for situations where the original classification can actually be shown to have been factually wrong, based on a misapplication of the true nature of the cost or the entity's own established classification policy, given the facts genuinely available at the time.
