Accounting Changes and Error Corrections: CPA FAR Exam Guide

Overview of ASC 250: Accounting Changes and Error Corrections

ASC 250 establishes the requirements for accounting for and reporting changes in accounting principles, changes in accounting estimates, changes in reporting entities, and corrections of errors. Each type of change has a distinct accounting treatment. This is a critical FAR topic because confusing the different treatments is a common exam pitfall.

Change in Accounting Principle

A change in accounting principle occurs when an entity adopts a generally accepted accounting principle different from the one it previously used. Examples include changing from LIFO to FIFO for inventory valuation, changing the method of depreciation (though this is often treated as a change in estimate effected by a change in principle), or adopting a new accounting standard.

Retrospective Application

Changes in accounting principles are generally accounted for retrospectively. This means the entity adjusts the financial statements of prior periods as if the newly adopted principle had always been used. The cumulative effect of the change on periods prior to those presented is reflected as an adjustment to the beginning balance of retained earnings in the earliest period presented.

Retrospective application requires the entity to determine the cumulative effect of the change on all prior periods, adjust the carrying amounts of assets and liabilities as of the beginning of the earliest period presented, and adjust the offsetting entry to retained earnings. Comparative financial statements are restated to reflect the new principle.

Exceptions to Retrospective Application

Retrospective application is not required when it is impracticable to determine the period-specific effects or the cumulative effect. In such cases, the entity applies the new principle prospectively from the earliest date practicable. Additionally, some new accounting standards specify their own transition method (such as a modified retrospective approach), which overrides the general retrospective requirement.

Change in Accounting Estimate

A change in accounting estimate results from new information, experience, or developments that revise a previous estimate. Examples include changes in the estimated useful life of a depreciable asset, changes in the estimated residual value of an asset, revisions to bad debt estimates, and changes in warranty cost estimates.

Prospective Treatment

Changes in accounting estimates are accounted for prospectively. The change is reflected in the period of the change and future periods, if applicable. Prior period financial statements are not restated. For example, if a company changes the estimated useful life of a machine from 10 years to 8 years at the beginning of Year 5, the remaining book value (minus residual value) is depreciated over the revised remaining life (3 years instead of 5).

Change in Estimate Effected by a Change in Principle

When a change in accounting principle is inseparable from a change in estimate (such as changing from the declining-balance depreciation method to straight-line), the change is treated as a change in estimate (prospective application). The rationale is that the change in principle is being made because of new information about the expected pattern of economic benefits.

Change in Reporting Entity

A change in reporting entity occurs when a change results in financial statements that are effectively those of a different entity. Examples include presenting consolidated financial statements for the first time (when a parent acquires a subsidiary) or changing the specific subsidiaries included in consolidated financial statements.

Retrospective Application

Changes in reporting entity are accounted for retrospectively. Comparative financial statements for all prior periods presented are restated to show the financial information for the new reporting entity.

Correction of an Error

An error is a mistake in previously issued financial statements resulting from mathematical errors, errors in applying GAAP, or oversight or misuse of facts that existed at the time the financial statements were prepared. Errors do not include changes in estimates based on new information.

Restatement

The correction of a material error in previously issued financial statements is accounted for as a prior period adjustment. The entity restates the financial statements of the prior periods affected. The cumulative effect of the error on periods prior to those presented is reflected as an adjustment to beginning retained earnings of the earliest period presented. This is similar to retrospective application for a change in principle but is distinct because it involves an error, not a voluntary change.

Summary of Treatments

• Change in principle: Retrospective application (restate prior periods).
• Change in estimate: Prospective application (current and future periods only).
• Change in estimate effected by a change in principle: Prospective application.
• Change in reporting entity: Retrospective application (restate prior periods).
• Error correction: Restatement of prior periods (prior period adjustment).

Exam Preparation Tips

• Memorize the four categories and their treatments: two are retrospective, two are prospective, and one is restatement.
• The biggest exam trap is confusing a change in estimate with a change in principle. If the change is driven by new information, it is usually an estimate change.
• A change in depreciation method is treated as a change in estimate (prospective), not a change in principle.
• Error corrections require restatement, which means adjusting beginning retained earnings and restating prior comparative financial statements.
• Know that some new standards have their own transition methods that override the default retrospective approach.
