Accounting change

Working definition

A change in an accounting principle, an accounting estimate, or the reporting entity; correction of an error in previously issued statements is a separate route.

Also calledChange in accounting

A controller calls three year-end items “accounting changes.” The first adopts a required revenue amendment. The second revises a warranty rate after new claims experience. The third corrects a prior omission of a signed contract. The shared label hides three different reporting routes.

Open the file with four questions: What amount or boundary changed? What event or evidence caused it? What information existed at each reporting date? Which authority and transition instructions applied then? Only after those questions can the team route principle, estimate, reporting entity, or error.

The distinction changes the message to readers. Retrospective application says comparatives are recast for a supported accounting change. Restatement says the previously issued statements contained an error. Prospective treatment says the estimate changed with later information. These are not interchangeable ways to reach the same numbers.

Start with the route

ASC 250-10-45-1 begins with consistent use of an adopted principle. A change is therefore an exception that needs a named cause and reporting route. Keep the error analysis separate: an error correction is not one of the three accounting-change types.
