Reputation Audit٫Audit Reporting Lag and Restatement of Financial Statements

Abstract The main reason for the existence of an independent audit profession is accreditation to financial statements. accreditation means to ensure reliance on financial statements, but sometimes auditors may not make proper comments due to the inability to detect material misstatement of financial statements or due to errors or fraud. Therefore, audited financial statements of past periods may be restatemented due to significant accounting mistakes that could lead to loss of public trust in the auditor's opinion.The purpose of this study is to Investigate the relationship between auditor's reputation, delay in audit reports, and restatements of financial statements in listed Companies in Tehran Stock Exchange from the beginning of 2013 to 2017. The research method is correlation based on multivariate regression. In order to investigate and test the variables of research, 100 firms have been used as examples. In this study, two criteria have been used to measure auditor's reputation, type of auditor and auditor's fees. The results of the research show that there is a positive relationship between the first criterion of auditor's reputation with delay in audit reports and a negative relationship between the second criterion of auditor's reputation with delay in audit reports. Also the results of the research detect that there is a negative relationship between the first criterion of auditor's reputation with restatements of financial statements and a positive relationship between the second criterion of auditor's reputation with restatements of financial statements.
