ISSB Standards S1-83: S1.83 to 86: Errors

What does S1-83 require?

Material prior period errors (omissions and misstatements from failing to use, or misusing, reliable information that was available and could reasonably have been obtained, including mathematical mistakes, misapplied metric definitions, oversights and fraud) are corrected by restating comparatives unless impracticable, distinguished from changes in estimates; applying B55 to B59 the entity discloses the nature of the error, the correction for each prior period presented or, if impracticable, the circumstances and how and from when it was corrected, restating from the earliest practicable date.
