The number of US companies forced to withdraw financial statements because of accounting errors has surged to a nine-year high, raising questions about why mistakes are going unnoticed by auditors.
In the first 10 months of this year, 140 public companies told investors that previous financial statements were unreliable and had to reissue them with corrected figures, according to data from Ideagen Audit Analytics.
That is up from 122 in the same period last year and more than double the figure four years ago. So-called reissuance restatements cover the most serious accounting errors, either because of the size of the mistake or because an issue is of particular concern to investors.
