Errors
An error is an error discovered in the current financial period but it relates to one or more previous financial periods. Such errors arise due to mathematical mistakes, misapplication of accounting policies, oversights and fraud.
The statement requires that if such an error is material i.e. the previously reported financial statements were materially misstated or misrepresented, then, the opening balances of the current financial period must be restated and if practical, the previous financial statements should be restated. Therefore an error requires retrospective application.
