Whenever the auditor expresses an opinion that is other than unqualified, a clear description of all the substantive reasons should be included in the report and, unless impracticable, a quantification of the possible effect(s), individually and in aggregate, on the financial statements should be mentioned in the auditor's report.
In circumstances where it is not practicable to quantify the effect of modifications made in the audit report accurately, the auditor may do so on the basis of estimates made by the management after carrying out such audit tests as are possible and clearly indicate the fact that the figures are based on management estimates.
Ordinarily, this information would be set out in a separate paragraph preceding the opinion or disclaimer of opinion and may include a reference to a more extensive discussion, if any, in a note to the financial statements.
