Required accounting-principle change

Working definition

A change in accounting principle made to adopt authoritative requirements, using the scope, effective date, transition method, and elections supplied by the pronouncement.

Also calledMandated principle change

“The standard is effective” is not an adoption plan. The team needs the entity class, fiscal calendar, interim rule, permitted early-adoption date, transition method, transition-date definition, practical expedients, elections, disclosure periods, and interaction with previously issued statements.

If the pronouncement specifies prospective, modified-retrospective, or another method, that instruction controls. Topic 250's retrospective framework is not a menu from which management selects a more convenient route. The workpaper keeps current requirements, issued pending content, and adopted pending content in separate columns so an effective-date headline cannot silently rewrite the ledger.

Follow the update's transition terms

ASC 250-10-45-3 says a new Codification update normally provides its own transition requirements. Those terms take priority over Topic 250's default retrospective method.

For example, an update may require a cumulative adjustment on the first day of adoption and leave earlier comparative periods unchanged. Another may require recast comparatives. The phrase “required change” does not tell the accountant which result to book. Copy the exact scope, date, method, expedients, and disclosure periods into the adoption matrix, then test the complete affected population against them.
