ObjectiveThe rotation and TENURE of AUDIT partners are crucial factors for large corporations, as they significantly affect the quality of financial reporting. This study is among the first to provide empirical evidence on the relationship between AUDIT partner TENURE and AUDIT quality. The research aims to explore this relationship while examining the moderating role of switching AUDIT FIRMs.MethodsThe current research was conducted within the unique context of Iran, focusing on evaluating the turnover of AUDIT FIRM partners. To measure this turnover effectively, the study employs the research model developed by Giper et al. (2021). By applying this model in the Iranian context, the research aims to uncover insights specific to regulations that influence AUDIT partner rotation. This model provides a structured framework for analyzing the relationships between partner TENURE, AUDIT quality, and financial reporting outcomes. The study examined companies listed on the Tehran Stock Exchange. A total of 136 companies were selected as the sample for the period from 2013 to 2021, yielding 1,224 observations. The data was analyzed using the panel data method.ResultsAfter testing the hypotheses, the results showed that rotating AUDIT partners led to an increase in the disclosure of internal control weaknesses. In contrast, longer AUDIT partner TENURE was associated with a decrease in financial statement restatements and the disclosure of internal control weaknesses.  ConclusionThe current research contributes to the existing literature on AUDIT FIRM partner turnover and its relationship with AUDIT quality indicators in companies. It sought to provide valuable evidence regarding the implications of AUDIT FIRM partner turnover and TENURE, shedding light on how these factors influence financial reporting standards. Based on the theoretical foundations, the research findings indicate that when AUDIT partners at a FIRM change frequently, there may be signals to investors that the company wishes to manipulate its financial reports. This could be due to the new AUDITor's lack of familiarity with the company. Additionally, the research findings suggest that as the turnover of AUDIT FIRM partners increases, there may be a higher likelihood of disclosing internal control weaknesses, which can be seen as a measure of AUDIT quality. Conversely, when a partner has been with an AUDIT FIRM for a longer period, there may be fewer financial restatements and internal control weaknesses, indicating higher AUDIT quality. However, when both the partner's TENURE and the FIRM's change cycle increase at the same time, there may not be a significant change in accruals, financial restatements, and disclosure of internal control weaknesses as measures of AUDIT quality. This issue may stem from the fact that many AUDITing institutions in Iran tend to rely heavily on the previous year's worksheets and documentation prepared by prior AUDITors when conducting their AUDITs. The practice is often used for AUDIT planning, budgeting, and gathering necessary information for the current year's AUDIT.

This study examines whether the length of the relationship between a company and an AUDIT FIRM (AUDIT-FIRM TENURE) is associated with financial reporting quality. Using two proxies for financial reporting quality. The population of this study is that the companies accepted the Tehran Stock Exchange, according to the definition of the study for The period of AUDIT-FIRM TENURE which is at least five consecutive years. Time domain of research is 1381 – 1390 (2002-2011) and the data evaluated in this study is extracted from the AUDITed financial statement of The company’s stocks. It is explained that the Pearson correlation test and multiple regression to investigate the relationship between independent and dependent variables and also determining the direction and extent of these relationships are considered. We found a relationship between short AUDIT-FIRM TENURE of one to two years and quality of financial reports. In contrast, we found no evidence of relative financial reporting quality for longer AUDIT FIRM TENUREs and medium AUDIT FIRM TENUREs.

Introduction: High-profile corporate failures that occurred at the beginning of this century have raised concern about the reliability of companies' financial statements. While the primary responsibility for preparing accurate financial statements rests with company management and boards, questions also have been raised about the quality and independence of external AUDITors. Regulators and standard setters have attempted to enhance AUDIT quality through rules impacting on AUDITor independence (For example, the Sarbanes-Oxley Act of 2002)...

The purpose of this research is to investigate the relationship between AUDIT partners' narcissism and AUDIT fees, considering the role of TENURE and busyness of the AUDIT partner. This research is applied in terms of purpose, and in terms of method is correlation and Ex-Post Facto. The statistical population of this research was the FIRMs accepted in Tehran Stock Exchange, during the years 1394 to 1400, and the data of 82 FIRMs were selected by the systematic elimination method, and the hypotheses were established using multiple regressions for panel data, using the fixed effects method, through EViews software was tested. The results of the research showed that the narcissism of the first partner signing the AUDIT report has no significant relationship with the AUDIT fee and the TENURE and busyness of this partner has no effect on this relationship. But the second partner's narcissism is positively and significantly related to AUDIT fees. Between TENURE and busyness of this partner, only TENURE has a reducing effect on these relationship.The characteristics of the second AUDIT partner are more decisive on the pricing of AUDIT services than the first partner. However, AUDIT institutions, knowing the level of narcissism of their partners, in addition to reducing the costs spent on a narcissistic partner AUDIT project and the possibility of increasing their earnings can increase their competitive advantage by reducing the price of the services provided.

The aim of this research is to investigate the effect of AUDIT quality measures on investment risk in companies listed in Tehran Stock Exchange. AUDIT quality measures in this study are AUDIT FIRM size, AUDIT specialist and AUDIT TENURE. For this purpose three hypotheses were developed and data of 120 companies in Tehran Stock Exchange for the period between the years 1383 to 1389 were used. To test the hypotheses, multiple regression techniques and panel data methods were used. The results showed that AUDIT FIRM size and AUDIT TENURE are significantly positive and AUDIT specialist significantly negative impact on investment risk in companies listed in Tehran Stock Exchange.

In accordance with existing rules and regulations, a FIRM's external AUDITors can play a significant role in identifying and disclosing material weaknesses of internal controls. Accordingly, the purpose of this study is to examine the TENURE and rotation of external AUDITors (at the level of the institution and the partner) and the material weaknesses of internal controls over financial reporting. The statistical population of this research is FIRMs listed in Tehran Stock Exchange during the years 2012 to 2019 and the method of data analysis is logistic regression. Results show that there is a positive and significant relationship between the TENURE of the external AUDITor (at the level of the institution and the partner) and the disclosure of material weaknesses of internal controls over financial reporting in the external AUDITor's report. There is also a positive and significant relationship between the AUDIT FIRM's rotation and the disclosure of material new weaknesses in the internal controls over financial reporting in the external AUDITor's report. However, no significant relationship is observed between the AUDIT FIRM's partner rotation and the disclosure of material new weaknesses in the internal controls on financial reporting in the external AUDITor's report.
