The report was compiled on the basis of some of the company’s invoices the dates of which had been altered (‘the Irregularity’). As a result, the report exaggerated the profit of the company and Andrew suffered a loss from the transaction.Before the report was made, the auditors were aware of the Irregularity. However, they did not make any enquiry or carry out an investigation of any kind about the Irregularity before they approved the report by signing it. In addition, the auditors mentioned nothing about the Irregularity in the report.Required:In relation to professional negligence:
