ASC 250: Retrospective Changes and the LIFO Exception
Principle changes are retrospective when practicable; adopting LIFO is prospective when prior-period LIFO data cannot be reconstructed. Compare Nellis's FIFO change to weighted-average versus LIFO in 20X6 statements that also present 20X5.
Try one first
Hint
Classify each item (change in accounting principle, change in estimate, or prior-period error). Remember GAAP's practical-impracticability exception for switching to LIFO and that errors originating before the earliest year presented are corrected by restating the earliest presented year and adjusting opening retained earnings.
Answer A. Changing to LIFO is treated prospectively when retrospective application is impracticable (here, prior-period LIFO data were not maintained). A revision of useful life and residual value is a change in accounting estimate and is applied prospectively. The advertising capitalization was an error originating in 20X4 (before the earliest year presented), so GAAP requires restating the earliest year presented (20X5) and adjusting beginning retained earnings at January 1, 20X5.
Why not B: This is tempting because candidates often default to retrospective treatment for accounting principle changes. It is incorrect because retrospective application is impracticable given missing prior LIFO data, and prior-period errors are corrected by restatement and an opening retained-earnings adjustment, not by a current-year 'cumulative' charge to income.
Why not C: This choice correctly treats the LIFO adoption prospectively but incorrectly restates a change in estimate (useful life/residual value), which is applied prospectively. It also uses the wrong opening retained-earnings date: when the error originated before the earliest year presented, the adjustment is to beginning retained earnings at the earliest presented date (1/1/20X5), not 1/1/20X6.
Why not D: This option correctly states the prior-period error correction but is incorrect on the other two points: changing to LIFO here should be applied prospectively because retrospective application is impracticable, and revising useful life/residual value is a prospective change in estimate, not a restatement.
Side by side
| FIFO to weighted-average | FIFO to LIFO | |
|---|---|---|
| Prior-period records | Prior-period effects can be determined. | Prior-period LIFO data were not maintained; retrospective application is impracticable. |
| Treatment | Retrospective application. | Prospective application beginning in 20X6. |
| 20X5 comparative amounts | Restate using weighted-average. | Leave amounts reported under FIFO unchanged. |
| Opening retained earnings | Adjust January 1, 20X5 for cumulative effects before 20X5. | No retrospective adjustment for the LIFO change. |
| Prior-period effects in 20X6 income | Do not record a current-year cumulative-effect charge. | Do not record a catch-up charge for prior-year LIFO differences. |
| Disclosure | Describe the change and why weighted-average is preferable. | Describe the change, why LIFO is preferable, and why retrospective application is impracticable. |
Key points
- Remember: ordinary principle changes rewrite prior years; LIFO adoption starts now when prior-period LIFO amounts cannot be reconstructed.
- Effects arising within the earliest year belong in that year's restated income, not its opening retained earnings.
- With only one year presented, put the cumulative prior-period effect in that year's opening retained earnings.
- An inventory count mistake is an error, not a change in accounting principle.
How the exam traps you
- Restating 20X5 after adopting LIFO despite impracticable retrospective application. Apply LIFO prospectively from 20X6; leave 20X5 on FIFO.
- Adjusting opening 20X6 retained earnings even though 20X5 is presented. Use opening January 1, 20X5 for cumulative effects arising before 20X5.
- Applying FIFO to weighted-average prospectively because management chose the change. Management's choice does not override retrospective application when practicable.
Question 2
Hint
Classify each item first: prior-period error, change in accounting principle, or change in accounting estimate. Then match each classification to its required timing of application.
Answer D. A mathematical spreadsheet error that caused an understatement in a prior period is a prior-period error requiring retrospective correction of prior-period amounts. A voluntary change in inventory costing (an accounting principle) should be applied retrospectively when practicable. A revision to expected credit losses based on new information is a change in accounting estimate and is applied prospectively.
Why not A: This is tempting because the error is discovered in Year 2, but prior-period errors are not simply run through current-year income, they require retrospective correction of prior-period amounts. The other two treatments are correct, making the error-treatment the trap.
Why not B: A cumulative-effect adjustment to opening retained earnings is not the standard treatment when retrospective application of a change in principle is practicable. Also, a change in estimate is always applied prospectively; presenting comparative statements does not make an estimate change retrospective.
Why not C: Candidates may overgeneralize that changes identified in the current year are prospective; however, a voluntary change in accounting principle (inventory method) is applied retrospectively when practicable, while a change in estimate is prospective.
Question 3
Hint
Classify each item first: one is a change in accounting principle, and the other is a change in accounting estimate.
Answer A. A change from FIFO to weighted-average is a change in accounting principle and, when practicable, is applied retrospectively under U.S. GAAP. That requires restating prior comparative periods and adjusting opening retained earnings of the earliest period presented for the cumulative effect. Revising an asset's useful life is a change in accounting estimate and is accounted for prospectively, with no restatement of prior periods.
Why not B: This is tempting because both items are described as "changes," but a revision of useful life is a change in estimate, not a change in accounting principle. Changes in estimate are recognized prospectively, so prior periods are not restated for the depreciation-life revision.
Why not C: This distractor misclassifies the inventory method change. The inventory change is a change in accounting principle that is retrospectively applied when practicable, so prior-period restatement and an opening retained earnings adjustment are required for that item.
Why not D: This option reverses the correct classifications. A voluntary but preferable change in inventory costing method is still a change in accounting principle and is generally applied retrospectively. A revised useful life based on new information is a change in estimate, not an error correction, and is handled prospectively.
Question 4
Hint
Classify each item first: change in principle, error correction, or change in estimate. Then ask which of those categories actually runs through beginning retained earnings.
Answer B. The inventory-method change is a change in accounting principle applied retrospectively; because Year 3 statements are noncomparative, beginning retained earnings are adjusted for the cumulative effect through December 31, Year 2, which is $35,000. The omitted Year 2 utilities accrual is a prior-period error that decreases beginning retained earnings by $9,000. The change in useful life is a change in estimate and is handled prospectively, so it does not affect beginning retained earnings. Net = +$35,000 − $9,000 = +$26,000.
Why not A: This answer incorrectly includes the $12,000 reduction in Year 3 depreciation (a change in estimate) in the beginning retained earnings adjustment. Changes in estimate are handled prospectively and do not alter beginning retained earnings.
Why not C: This option double-counts the inventory effect by adding the Year 1 ($28,000) and Year 2 ($35,000) differences. The $35,000 difference at December 31, Year 2 already reflects the cumulative effect through that date, so you should not add the Year 1 amount again.
Why not D: This choice recognizes the prior-period error but ignores the retrospective adjustment required for the change in accounting principle, which increases beginning retained earnings by $35,000.
Question 5
Hint
Classify each item first as a change in estimate, a change in accounting principle, or an error correction before deciding between prospective treatment and retrospective restatement.
Answer A. Change in depreciation method accompanied by revised life/residual is treated as a change in accounting estimate (often described as a change in estimate effected by a change in principle) and is accounted for prospectively. A voluntary change in inventory costing method is a change in accounting principle and is applied retrospectively when practicable. An omission from prior-year inventory due to a clerical error is a prior-period error and requires restating prior-period financial statements.
Why not B: This distractor misclassifies the inventory-method change. A FIFO→weighted-average switch is a change in accounting principle and is generally applied retrospectively when practicable, not merely prospective treatment.
Why not C: This choice incorrectly treats the depreciation-method change as requiring retrospective application and treats an actual prior-period error as a current-year recognition; in fact, depreciation-method changes are prospective, and prior-period clerical errors require restatement.
Why not D: This reflects a timing confusion: discovery in Year 3 does not determine the accounting method. Classification (change in estimate, change in principle, or error) governs whether treatment is prospective or retrospective.
Question 6
Hint
For each matter, decide whether management adopted a different acceptable accounting principle, updated an estimate because of new information, or is correcting a failure to apply GAAP to information that existed at the prior balance sheet date.
Answer B. Under ASC 250, changing the inventory cost-flow assumption (weighted-average to FIFO) is a change in accounting principle and, absent impracticability, should be applied retrospectively to prior periods. The omitted 12/31/20X5 warranty liability resulted from failing to record an accrual even though the warranty terms and sufficient claims data existed at that date; that omission is a prior-period error that must be corrected by restating the prior-period financial statements. Both adjustments affect prior-period amounts, but they are different classifications (retrospective application of a principle versus correction of an error) with different required disclosures.
Why not A: This is tempting because both items affect previously reported amounts, but the warranty omission arose from not applying GAAP to information that existed at 12/31/20X5; that is a prior-period error under ASC 250, not a change in accounting principle.
Why not C: This distractor confuses methods with estimates; switching inventory cost-flow methods is a change in accounting principle, not an estimate change, and the warranty liability should have been accrued in 20X5 based on information available then, making it a prior-period error rather than a later estimate.
Why not D: Although certain narrow situations are described as estimates affected by a change in principle, that characterization does not apply to switching inventory cost-flow methods; therefore the inventory change is a change in accounting principle (retrospective), and the warranty omission remains an error requiring restatement.
Common questions
When does ASC 250 require an opening retained earnings adjustment?
Adjust opening retained earnings of the earliest period presented for cumulative effects from earlier periods. Effects arising during a presented period belong in that period's restated results.
Is a change from FIFO to LIFO retrospective or prospective?
The tested change to LIFO is prospective because prior-period LIFO data were not maintained and retrospective application is impracticable. Start LIFO in the change year without restating prior periods.
What if retrospective application is impracticable under ASC 250?
Apply the change from the earliest practicable date, which may be the current period. Disclose why full retrospective application was impracticable.
