Accounting-standard adoption date

Working definition

The date on which an entity first applies new accounting requirements under the pronouncement's effective-date and early-adoption provisions.

Also calledStandard adoption date

A December issue date may lead to different adoption dates for a calendar-year public business entity, a June-year-end private company, and an entity that elects early adoption. A proposal has no adoption date at all.

The standards clock records the authoritative document, entity class, annual period wording, interim-period wording, permitted early-adoption conditions, fiscal calendar, elected date, and transition date. That clock prevents future or merely proposed guidance from entering the current ledger by accident.

Read the pronouncement first

ASC 250-10-45-3 says a new Codification update will normally give its own transition requirements. Those requirements settle when an entity must apply the change and whether early adoption is allowed. Topic 250 supplies a default only in the unusual case that the update gives no specific transition method.

Suppose an update is issued in December but applies to fiscal years beginning after the next December 15. A calendar-year entity does not adopt it on the issue date. The team maps the exact effective-date words to that entity's fiscal year, interim periods, and elected early-adoption date.
