Under FASB ASC 250, retrospective application of an accounting principle change requires restating prior period financial statements as if the new principle had always been applied. The change from FIFO to weighted-average increased 20X4 cost of goods sold by $70,000 ($4,070,000 - $4,000,000), which decreases pretax income by $70,000. The after-tax effect is $49,000 ($70,000 × 70% or $70,000 - $21,000 tax benefit), decreasing both income from continuing operations and ending retained earnings by $49,000. Answer A incorrectly uses the pretax amount without considering the tax benefit. Answer C incorrectly shows an increase when higher cost of goods sold decreases income. Answer D incorrectly suggests prospective application when retrospective application is required for voluntary principle changes. The key framework is that retrospective application affects both the income statement and balance sheet for all prior periods presented, with tax effects calculated at the applicable rate.

FASB ASC 250-10-50-1 requires disclosure of the nature of and reason for the accounting principle change, including an explanation of why the newly adopted principle is preferable. The entity must describe the method of applying the change (retrospective) and disclose the effects on financial statement line items and per-share amounts. Answer B inappropriately suggests disclosing earnings management motives when the standard requires stating the change is preferable based on improved financial reporting. Answer C incorrectly characterizes a principle change as an error correction. Answer D incorrectly references IFRS when dealing with U.S. GAAP requirements. The disclosure framework emphasizes transparency about why management believes the new principle provides more relevant and reliable information, supporting users' understanding of the change's business rationale beyond mere compliance.

FASB ASC 250 applies to not-for-profit organizations and requires retrospective application of accounting principle changes unless impracticable. Under the new principle for conditional grants per ASC 958, the $500,000 previously recognized as contribution revenue in 20X4 should not have been recognized because the barrier was not overcome. Retrospective application requires decreasing 20X4 contribution revenue by $500,000, which directly decreases the change in net assets by $500,000 (not-for-profits have no income taxes). Answer B incorrectly suggests the change in net assets would increase when removing revenue. Answer C incorrectly states not-for-profits apply changes prospectively when ASC 250 requires retrospective application. Answer D incorrectly suggests only a reclassification with no effect on total net assets. The framework for not-for-profit retrospective application mirrors for-profit entities except there are no income tax considerations, and the effect flows through change in net assets rather than net income.

FASB ASC 250-10-50-1 explicitly requires disclosure of the effect of retrospectively applied accounting principle changes on any per-share amounts presented, including earnings per share. When prior periods are restated for the principle change, basic EPS must be recomputed using the restated income from continuing operations for each period presented, and the effect of the change on EPS must be disclosed. Answer B incorrectly states EPS is not adjusted when it is specifically required by ASC 250. Answer C incorrectly suggests maintaining previously reported EPS when consistency requires restatement. Answer D incorrectly limits EPS restatement to cash flow effects when all retrospective adjustments affecting net income require EPS recalculation. The framework for EPS disclosure under retrospective application ensures that per-share metrics remain consistent with the restated financial statements and provides users with comparable trend information.

FASB ASC 250 requires retrospective application of voluntary accounting principle changes when the change is preferable and material. This means restating prior period financial statements as if the new principle had always been applied, adjusting beginning retained earnings of the earliest period presented for the cumulative effect, and providing comprehensive disclosure about the nature and effects of the change. Answer B incorrectly references extraordinary items, which were eliminated by ASU 2015-01. Answer C incorrectly suggests pro forma presentation when actual restatement is required. Answer D incorrectly treats a principle change as a change in estimate requiring prospective application. The retrospective application framework ensures comparability across periods by presenting all periods under the same accounting principle, with clear disclosure enabling users to understand the change and its effects.

FASB ASC 250 requires retrospective application when changing from the completed-contract method to percentage-of-completion method for long-term contracts. Under percentage-of-completion, the company would have recognized $2,000,000 in revenue and $1,600,000 in costs for 20X4, resulting in $400,000 of pretax income that was not recognized under completed-contract. The after-tax effect increases income from continuing operations by $300,000 ($400,000 × 75% or $400,000 - $100,000 tax expense). Answer B incorrectly uses the pretax amount without considering taxes. Answer C incorrectly shows a decrease when recognizing previously unrecognized profit increases income. Answer D incorrectly treats this principle change as a change in estimate requiring prospective application. The framework for retrospective application of construction accounting changes requires recalculating revenue and costs under the new method for all contracts in progress during prior periods presented.

When retrospectively applying a change from completed-contract to percentage-of-completion method, FASB ASC 250 requires adjusting beginning retained earnings of the earliest period presented for the cumulative effect. The $900,000 of previously unrecognized pretax gross profit increases retained earnings by $630,000 after considering the tax effect ($900,000 × 70% or $900,000 - $270,000 tax). The $270,000 tax obligation creates a deferred tax liability because this income will be taxable when recognized for tax purposes. Answer A incorrectly ignores tax effects. Answer C incorrectly shows a deferred tax asset and wrong retained earnings amount. Answer D incorrectly decreases retained earnings when recognizing previously unrecognized profit increases it. The framework for cumulative adjustments requires calculating the pretax difference between methods, determining the after-tax effect for retained earnings, and recognizing the appropriate deferred tax asset or liability.

FASB ASC 250 requires retrospective application of voluntary accounting principle changes, meaning prior periods presented must be adjusted as if the new principle had always been used. The company changed from FIFO to weighted-average, resulting in inventory being $60,000 lower under the new method ($1,200,000 - $1,140,000), which increases cost of goods sold and decreases pretax income by $60,000. The after-tax effect is $45,000 ($60,000 × 75%), decreasing retained earnings, while the tax benefit of $15,000 ($60,000 × 25%) decreases the deferred tax liability. Answer B incorrectly treats this as a change in estimate with no tax effects. Answer C incorrectly increases inventory when the weighted-average method results in lower inventory values. Answer D incorrectly applies prospective treatment to a principle change that requires retrospective application. The framework for retrospective application requires adjusting all affected balance sheet accounts as of the beginning of the earliest period presented, with the net effect flowing through retained earnings.

FASB ASC 250 requires recording a cumulative-effect adjustment to the beginning balance of retained earnings for the earliest period presented when retrospectively applying an accounting principle change. The change from FIFO to weighted-average decreased inventory by $40,000 ($900,000 - $860,000), which represents higher cumulative cost of goods sold under the new method. The after-tax effect decreases retained earnings by $30,000 ($40,000 × 75%), while the tax benefit of $10,000 ($40,000 × 25%) creates a deferred tax asset (not liability) because the company has already paid taxes on income that is now being reduced. Answer B incorrectly applies prospective treatment. Answer C incorrectly increases inventory and creates a deferred tax liability. Answer D incorrectly states no entry is permitted when ASC 250 explicitly requires adjustment entries. The framework for cumulative-effect adjustments involves debiting retained earnings for the after-tax effect and adjusting the related balance sheet accounts to their corrected amounts.

FASB ASC 250-10-50 requires comprehensive disclosure when an accounting principle change is applied retrospectively, regardless of whether the entity is for-profit or not-for-profit. Required disclosures include the nature of and justification for the change, the method of applying the change (retrospective), and the effect on each financial statement line item and any per-unit measures for each period presented. Answer B incorrectly limits disclosure requirements for not-for-profits when ASC 250 applies equally to all entities. Answer C incorrectly characterizes a voluntary principle change as an error correction. Answer D incorrectly suggests disclosure only in MD&A when note disclosure is explicitly required by ASC 250. The disclosure framework ensures financial statement users understand what changed, why it changed, how it was applied, and the quantitative effects on all periods presented, enabling proper analysis of trends and comparability.
