Nature of errors and contingencies

Learning objectives

• Identify an error (mathematical mistake, mistake in applying policies, oversight, misinterpretation of facts, fraud) and whether it is material or intentional.L1, L2
• Distinguish the correction of an error from the outcome of a contingency or the revision of an estimate.L2, L3

Normative references

• IAS 8 §5Definitions: accounting policies — the specific principles, bases, conventions, rules and practices applied by an entity in preparing and presenting financial statements; accounting estimates — monetary amounts in financial statements that are subject to measurement uncertainty; 'material' — used as defined in IAS 1 (para. 7); prior period errors — omissions from, and misstatements in, the financial statements for one or more prior periods arising from a failure to use, or misuse of, reliable information that was available when those financial statements were authorised for issue and could reasonably be expected to have been obtained and taken into account (mathematical mistakes, mistakes in applying accounting policies, oversights, misinterpretations of facts, fraud); retrospective application — applying a new accounting policy as if that policy had always been applied; retrospective restatement — correcting the recognition, measurement and disclosure of amounts as if the error had never occurred; prospective application — applying a new policy to transactions occurring after the date of the change, and recognising the effect of a change in estimate in the current and future periods affected; impracticable — a requirement the entity cannot apply after making every reasonable effort to do so, which, for a prior period, covers three situations: effects not determinable; assumptions required about what management's intent would have been at the time; significant estimates for which it is impossible to distinguish objectively information that provides evidence of circumstances that existed at that date and that would have been available when the financial statements were authorised for issue.
• IAS 8 §41Errors can arise in the recognition, measurement, presentation or disclosure of elements of financial statements. Financial statements do not comply with IFRSs if they contain material errors, or immaterial errors made intentionally to achieve a particular presentation. Current period errors discovered in that period are corrected before the financial statements are authorised for issue; material errors discovered in a subsequent period are corrected in the comparative information presented in the financial statements for that subsequent period.
• IAS 8 §48Corrections of errors are distinguishable from changes in accounting estimates: estimates are by their nature approximations that may need revision as additional information becomes known. For example, the gain or loss recognised on the outcome of a contingency is not the correction of an error.
