Information-availability timeline

Put the dates in four columns. Record when the economic fact existed and when evidence of it was created. Then record when the evidence was reasonably available and when the team used or failed to use it. A signed contract may predate year-end but reach accounting later. A claims trend may emerge only after the original estimate. A later audit may uncover a mathematical mistake in the original workpaper.

The timeline does not decide intent or negligence. It creates the recoverable record needed to distinguish new information from oversight or misuse of an earlier fact. Contradictions and missing evidence remain open items rather than being forced into the preferred classification.

Control hindsight

ASC 250-10-45-10 asks whether information now used for a significant estimate would have been available when the earlier accounting was performed. The answer needs dated evidence, not a later outcome alone.

For example, a February claims report may confirm a defect that existed at December 31. If a November quality report was reasonably available to the reporting team, omission may point toward error. If the evidence first became available after issuance, it may support a later estimate change. Preserve both paths until distribution logs, reporting dates, and the original workpapers resolve the timeline.
