Retrospective vs. Prospective Applications

18.2 Retrospective vs. Prospective Applications

Accounting standards often require changes in how transactions and events are recognized, measured, and presented in the financial statements. When these changes occur—or when errors are discovered—an entity may need to adjust previously issued financial statements or adjust financial reporting going forward. This section explores the two primary methods of adjusting for accounting changes: retrospective application and prospective application. We highlight the specific requirements, walk through illustrative examples, and emphasize the critical role of “impracticability” exceptions.

Overview of Accounting Changes

Changes in accounting can stem from various sources, including:

• Changes in accounting principles (e.g., shifting from one generally accepted principle to another).
• Changes in accounting estimates (e.g., adjusting the useful life of fixed assets, reevaluating allowance for uncollectible accounts).
• Changes in the reporting entity (e.g., consolidating a subsidiary that was previously unconsolidated).
• Corrections of errors in the financial statements (e.g., mistakes in recording transactions, computational errors).

The choice between retrospective and prospective approaches hinges on the type of accounting change. In many instances, authoritative guidance under U.S. GAAP (notably FASB ASC 250) outlines whether an entity must restate prior-year financial statements (retrospective) or adjust only the current and future reporting periods (prospective).

Retrospective Application

Retrospective application involves adjusting prior-period financial statements as if the new accounting method or principle had always been in use. This method aims to preserve comparability across periods, ensuring users can see the financial statements on the same measurement basis.

When is Retrospective Application Required?

Retrospective application is generally required for changes in accounting principles—unless it is deemed impracticable—because these changes can significantly alter how transactions are measured and presented. For example, changing from the completed-contract method to the percentage-of-completion method for long-term construction contracts typically requires a restatement of all prior periods presented.

Under ASC 250, a change from one acceptable accounting principle to another is permissible “if the newly adopted principle is preferable,” meaning it is more relevant or represents an improvement in the clarity and consistency of financial reporting.

Key Objectives of Retrospective Application

1. Enhancing Comparability:
   By adjusting prior periods, users can compare results under the same accounting method across all years presented.

2. Transparency:
   Restating previously issued financial statements clarifies how the change affects trends, ratios, and other performance metrics.

3. Accuracy in Cumulative Effects:
   Any cumulative effect of the change prior to the earliest period presented is typically recorded as an adjustment to the opening balance of retained earnings (or other relevant equity accounts) in the earliest period being restated.

Steps in the Retrospective Approach

Retrospective restatement involves a series of steps to ensure financial statements from previous periods reflect the newly adopted principle.

1. Identify the Affected Accounts
   Determine which financial statement line items, including assets, liabilities, revenues, expenses, or equity, are affected by the change in principle.

2. Recalculate Prior Periods
   Recalculate the balances for each period as if the new principle had been in place during those periods. Adjust the amounts recognized in the balance sheet and the statement of operations (or comprehensive income, if applicable).

3. Record the Cumulative Effect
   If periods prior to the earliest year presented are affected, the net effect is an adjustment to the opening balance of retained earnings (or other relevant equity type, such as net assets for not-for-profits). Disclose this adjustment in the footnotes.

4. Update and Disclose
   Restated financial statements for all prior periods presented must clearly state they have been adjusted, describing the nature and reasons for the change, the method of applying the change, and, if applicable, the cumulative effect on retained earnings.

Example of Retrospective Application

Suppose a manufacturing company decides to change its method of inventory valuation from the LIFO (Last-In, First-Out) method to the FIFO (First-In, First-Out) method. Management believes FIFO better reflects the actual flow of goods and is more comparable to other firms in the industry.

• Identify the affected accounts: Inventory, Cost of Goods Sold (COGS), Retained Earnings.
• Recalculate prior year financial statements: Adjust previous COGS and ending inventory balances for the prior year to reflect FIFO.
• Record any cumulative effect: If the company has multiple years of financial data presented, it adjusts the beginning retained earnings of the earliest presented period for the cumulative difference in inventory calculations.
• Update footnotes: Disclose the exact reason for the change, the method of applying it, and provide a tabular comparison of the original vs. restated amounts.

Impracticability Exception

Although retrospective restatement is the default requirement for changes in principle, there are situations where this approach can be impracticable. For example, data from years past may be unavailable, incomplete, or simply impossible to reconstruct accurately without excessive cost. If retrospective restatement creates an undue burden or significant inaccuracy, authoritative guidance allows for prospective (or modified retrospective) application.

Under ASC 250, if retrospective application is deemed impracticable, an entity applies the new accounting principle to the earliest possible period—often the beginning of the current period. Disclosures, however, must explicitly describe why the retrospective approach was impracticable, along with the method used to transition to the new principle.

A classic instance of the impracticality exception is when a company lacks critical inventory records to restate from LIFO to FIFO for prior years. If, after making good-faith efforts, the historical data remains unattainable, the entity can adopt FIFO prospectively and adjust only the current (and future) period.

Prospective Application

Prospective application is used for:

• Changes in Accounting Estimates
• Certain circumstances surrounding the impracticability of retrospective restatement
• New transactions or events that require different treatment, but older transactions remain as previously reported

Fundamental Concept of Prospective Application

In prospective application, the adjustment affects only current and future financial statement periods. No prior-period restatement is done, and no opening balance adjustments are made to previously presented equity balances. Instead, the new estimates or principle changes are reflected in the period of change and forward.

Examples of changes in estimates include:

• Reassessing the remaining useful life of a major machine.
• Adjusting the allowance for doubtful accounts based on newly available customer payment patterns.
• Estimating new salvage values for depreciable assets due to changes in market conditions.

Because estimates rely on judgments that can change with new information, prospective application ensures that previously issued statements remain intact—they reflected the best estimate at that time.

Example of Prospective Application for a Change in Estimate

ABC Construction reevaluates the useful life of its cranes. It originally projected a 10-year service life, but new engineering reports suggest 12 years is more realistic. This change in estimate is recorded prospectively:

• ABC adjusts depreciation for the current year based on the new remaining useful life.
• No prior financial statements are altered, as the company acted upon the best information at the time of the original estimate.
• The footnotes disclose the nature of the change in estimate and the financial impact on current and future financial statements.

Comparing Retrospective and Prospective Approach

Below is a high-level comparison of these two methods:

Visual Representation

The decision tree below illustrates the typical process for determining whether retrospective or prospective application is required:

    flowchart LR
	    A((Start)) --> B{Type of Change?}
	    B --Change in Principle--> C{Is Retrospective<br/>Application Practicable?}
	    B --Change in Estimate--> E[Prospective]
	    C --Yes--> D[Retrospective]
	    C --No--> E[Prospective <br/>(Due to Impracticability)]

In this simplified flowchart, if the accounting change is a “change in principle” and retrospective is practicable, prior-period financial statements are restated. If not practicable—or if it’s purely a change in estimate—prospective accounting applies.

Case Study: Changing from Average Cost to FIFO

Alpha Co. has historically used the average cost method to value inventory. Due to supply chain changes and comparability issues, management decides that FIFO is more representationally faithful.

• Step 1 – Accounting Principle vs. Estimate: This is a change in accounting principle because it moves from one acceptable method (average cost) to another (FIFO).
• Step 2 – Retrospective Approach Required: Under U.S. GAAP, retrospective restatement is the standard. Management examines the availability and reliability of past inventory data to ensure restatement is feasible.
• Step 3 – No Impracticability Found: Alpha Co. has sufficient historical records. It recalculates ending inventory and COGS for prior periods, restates the prior year’s balance sheet and income statement, and adjusts the opening balance of retained earnings in the earliest year presented for pre-restatement effects.
• Step 4 – Footnotes: Alpha Co. clearly discloses the nature of the change, why FIFO is preferable, and reconciles previously reported amounts to the restated amounts.

Had Alpha Co. discovered incomplete records from certain earlier years, it might have sought the impracticability exception. In that scenario, Alpha Co.’s new policy could be applied prospectively from the earliest date for which complete records existed, while prior years would remain on the average cost method.

Common Pitfalls and Practical Tips

• Not Distinguishing Between Principle and Estimate: A frequent error occurs when companies mistakenly treat a change in estimate (e.g., update to depreciation method) as a change in principle or vice versa. Proper classification is crucial, as a misclassification can lead to incorrect restatements.
• Assessing Impracticability Prematurely: Entities should not jump straight to prospective application without fully documenting why retrospective restatement is not feasible. Auditors typically request thorough evidence that restating prior periods is impracticable.
• Failing to Disclose the Cumulative Effects: When restating prior periods, some organizations overlook adjusting the earliest period’s opening retained earnings. This oversight understates or overstates net income and can mislead anyone analyzing trends in performance.
• Overlooking Tax Implications: Changes in financial reporting can also affect deferred taxes. Ensure that restatement or prospective changes capture associated tax impacts and that management discloses any related income tax effects in the footnotes.

Best Practices for Implementation

• Maintain Comprehensive Records: To avoid impracticability concerns, keep granular data on key accounts such as inventory, revenue recognition, and depreciation.
• Align with Industry Peers: If changing to a reminiscent practice in your industry, ensure you have considered relevant industry guidance and benchmarks.
• Document Rationale Thoroughly: Prepare memoranda supporting why a new principle is preferable or why a revised estimate better reflects current circumstances.
• Engage Stakeholders Early: Discuss proposed changes with auditors, investors, and governance bodies to manage expectations about restated or updated financial data.
• Ensure Adequate Disclosure: Provide a robust description of the change, its financial impact, and how it enhances the reliability and relevance of the financial statements.
