• IAS 8 §24When it is impracticable to determine the period-specific effects for one or more prior periods presented, the entity applies the new accounting policy to the carrying amounts of assets and liabilities as at the beginning of the earliest period for which retrospective application is practicable (which may be the current period) and makes a corresponding adjustment to the opening balance of each affected component of equity for that period.
• IAS 8 §25When it is impracticable to determine, at the beginning of the current period, the cumulative effect of applying the new accounting policy to all prior periods, the entity adjusts the comparative information to apply the new policy prospectively from the earliest date practicable.
• IAS 8When the new accounting policy is applied prospectively because it is impracticable to apply it retrospectively, the portion of the cumulative adjustment relating to periods before that date is disregarded.
• IAS 8 §53Hindsight is not used when applying a new accounting policy to, or correcting amounts for, a prior period, either in making assumptions about what management's intentions would have been at the time or in estimating the amounts recognised, measured or disclosed.

• Notine cannot determine the period-specific effects of a change in policy for the comparative period. What does IAS 8 require?L3
• At the beginning of the current period, Dresac cannot determine the cumulative effect of its new policy on all prior periods. What does it do?L3
• When retrospective application of a new policy is required, to what extent may the entity depart from it?L3
• When applying a new policy to 2024, Nyrède could use a price index published in 2025 showing how a market actually moved. Is this allowed?L4
• Which statements about the limits of retrospective application are correct?L3
• Of the arguments put forward by Fosia for not applying its new policy retrospectively, which can support impracticability?L4
• To estimate in 2025 an amount relating to 2023 as part of retrospective application, which information may Sylbix use?L4
• After every reasonable effort, Grytore cannot determine any effect of its new policy for the comparative period; the earliest practicable period is the current period, which began on 1 January 2025. At that date, the assets concerned are worth {new_policy_amount} under the new policy and {old_policy_amount} under the old one (tax effect ignored). What adjustment should be made to 2025 opening equity?L3
• Puscouël's 2023 records were destroyed and cannot be rebuilt; the earliest practicable period is 2024, the earliest period presented. Carrying amounts of inventories, new and old policy: {new_1_jan_2024} and {old_1_jan_2024} at 1 January 2024; {new_31_dec_2024} and {old_31_dec_2024} at 31 December 2024 (tax effect ignored). Compute the 2024 opening adjustment and the effect on 2024 profit.L3
• For Kirvore, the earliest practicable period is the current period. At the beginning of that period, the new policy increases carrying amounts by {pre_tax_adjustment}, without changing tax bases; rate of {tax_rate} (case data). Compute the net adjustment to opening equity.L4
• Chudence cannot determine the cumulative effect of its new policy at the beginning of the current period; the earliest date practicable is 1 October 2024. The new policy changes the result of transactions after that date by {monthly_effect} a month (case data), i.e. {months_after_date} months in 2024. What is the effect on the 2024 comparative?L3
• To apply a new policy to 2024, Chesax must estimate an amount at the end of 2024. According to the file prepared at the time (estimation method provided by the case): a {probability_high} chance of an amount of {amount_high} and {probability_low} of an amount of {amount_low}. The outcome known in 2025 is {actual_outcome_2025}. What amount should be used for 2024?L4
• An IT failure permanently erased Clurnade's 2023 data; the 2024 data are complete. Clurnade presents 2025 and 2024 and changes policy in 2025. Which treatment applies?L3
• Cléstal cannot determine the cumulative effect of its new policy for any prior period, for lack of data, except for transactions entered into from 1 July 2024, when a new system started collecting the necessary information. Which treatment applies?L4
• Fyscot's finance director claims that retrospective application of the new policy is 'impracticable': the data exist in the archives, but extracting them would be costly and take two months. What is the conclusion?L4
• Vrédine changes policy in 2025. The 2023 data are incomplete; the 2024 data can be partly rebuilt. Write the note justifying the treatment adopted and the earliest practicable period.L4
• Gaulax's audit committee has doubts: management proposes to apply the new policy prospectively from a 2024 date rather than retrospectively. Write a critical analysis of the proposal.L4
