The purpose of this study is to explore the economic impact of financial restatements by major customers on the audit opinion of their suppliers, showing that non-financial information disclosure potentially helps auditors make better assessments.

Using a sample of China’s listed firms from 2007 to 2021, the authors aim to find the relationship between customers’ financial restatements and their suppliers’ audit opinions. Heckman selection model, placebo tests and other robustness checks are used as well.

The findings reveal that customers’ financial restatements have a significant effect on the likelihood of suppliers receiving modified audit opinions. This relationship is pronounced when suppliers face a higher level of financial constraints, exhibit poorer accounting conservatism or receive more negative media coverage. Additionally, this effect occurs through increased business risk and information risk, which heightens auditors’ perceived audit risk. Moreover, the study highlights the influence of switching costs, auditor expertise and restatement severity on this relationship.

Risks originating from customers can spread along the supply chain, emphasizing the necessity for auditors to give heightened attention to both the audited firms and their customer information. Moreover, regulators should carefully consider the important impact of customer information disclosures to maximize the protection of the interests of external information users.

This study not only confirms the crucial role of customer information disclosures in annual reports for stakeholders and auditors but also contributes to the existing literature on customer–supplier relationships.

This paper aims to enrich the scope of the influence of media reports on the stock risk, and it also provides a path to support the research on the relationship between media reports and idiosyncratic risks in the stock market.

The authors select financial restatement samples of listed companies in China from Jan 2015 to Dec 2017 to explore the impact of the financial restatement on the idiosyncratic risk of stocks. Further, the financial restatement that has more media attention may play a more significant role in promoting the idiosyncratic risk.

The authors found that the financial restatement of listed companies has a significant positive effect on the idiosyncratic risk of stocks. Specifically, the idiosyncratic risk changed five months before the restatement. After the restatement, the idiosyncratic risk increased by 83.47 in five days then decreased slowly, which lasted about one year. The restatement caused by sensitive issues and legal issues has a greater impact on the idiosyncratic risk. Both current restatement and delayed restatements will increase the idiosyncratic risk of stocks, but the impact of the latter is higher than the former.

Possible deficiencies in the paper are that the number of restatements caused by major accounting errors is low. Therefore, no regular conclusions were drawn on the impact of the financial restatement caused by major accounting errors.

The conclusions provide a basis for targeted supervisory measures on the restatements of listed companies. The increase in financial restatements is closely related to the lack of governance mechanisms in the stock market. For investors, although the mystery of idiosyncratic volatility exists significantly in the market, the company's valuation level will affect the relationship between the idiosyncratic risk and expected return. Investors should pay attention to the intrinsic value of the company and should not blindly pursue stocks with a low idiosyncratic risk.

These conclusions may enrich the scope of the influence of media reports on the stock risk and also provide a path to support the research on the relationship between media reports and idiosyncratic risks in the capital market.

The purpose of this study is to examine the effects of chief financial officer (CFO) gender, board gender diversity and the interaction of both factors on financial reporting quality (FRQ) proxied by restatements.

Restatements indicate inaccurate financial reporting. The authors use fixed effects conditional logistic regression models to compare firms with and without restatements matched by size, industry and year. The authors’ unique matched–pair sample consists of 546 listed US firms from the period 2005–2016.

The authors’ results provide evidence that restatements are less likely when the CFO is a woman and when a higher proportion of women serve on the board of directors (BOD). Considering the interaction effects, the authors find evidence that women on the BOD are more effective at reducing restatement likelihood when the CFO is also a woman. And that although female CFOs reduce restatement likelihood generally, they have no statistically significant effect on restatement likelihood when the BOD is all-male.

To the best of the authors’ knowledge, this study is the first that the authors know of to consider how FRQ is affected by the interaction effects of CFO gender and board gender diversity. The findings corroborate upper echelons theory and extend the understanding of the effects of managerial gender diversity at a time when firms face growing pressure to increase gender diversity at the highest levels. The unique sample, methodology and findings provide new insights into the impact of gender on FRQ that has important policy implications.

This paper aims to examine the link between audit(or) type and restatements in Egypt, a complex and multifaceted auditing market. The usual big 4 versus non-big 4 comparison is insufficient as Egypt has a unique mix of private audit firms, one governmental agency (Accountability State Authority) and mandatory/nonmandatory audit services, including single, joint and dual audits.

The study uses a sample of listed companies in Egypt and analyzes the impact of auditor type and audit type on explicit, implicit and total restatements. The study uses logistic regression model to examine the underlying relationship.

Results show no relationship between auditor type and audit quality, positive association between non-big foreign CPA firms and total/implicit restatements and mixed results for the impact of dual audits on audit quality. The study found no link between auditor type and audit quality in Egypt. Egyptian audit firms linked to non-big 4 foreign Certified Public Accounting firms were positively linked to total and implicit restatements. Joint audits did not improve audit quality and were directly related to total and explicit restatements. Dual audits showed mixed results, positively associated with implicit restatements but inversely associated with explicit restatements.

The study provides valuable insights into the complexities of the auditing market in emerging markets and offers valuable insights for stakeholders in the financial statement users, audit firms and governmental agencies.

The purpose of this study is to investigate the association between nonaudit services (NAS) and out-of-period adjustments (OOPAs). Over the years, the number of OOPAs has risen while the number of restatements has decreased. This could indicate an improvement in financial reporting quality. It could also indicate the use of a type of stealth restatement for opportunistic purposes. These less prominent restatements are more likely to go undetected and could perpetuate opportunistic disclosure and mitigate the likelihood of unfavorable market reactions.

The authors use a two-stage multivariate regression analysis to examine the relationship between NAS and the reporting of an OOPA. The authors use prior research on NAS to guide the model development. The authors perform several robustness checks including different types of NAS and different characteristics of OOPAs.

The results indicate that NAS has a significantly negative association with the existence of OOPAs. The core findings suggest that NAS does not impair auditor independence. Rather, greater amounts of NAS may contribute to knowledge spillover, which leads to higher financial reporting and audit quality. The results are robust to several additional tests.

The results raise interesting implications for regulators, executives, auditors, investors and future research. The authors provide insight into the relationship between NAS and auditor independence.

To the best of the authors’ knowledge, prior research has not considered the effect of NAS on OOPAs. The authors contribute to the literature by providing evidence that OOPAs, a form of stealth restatements, is an important consideration in audit quality research.

The main objective on this research is providing evidence of the contagion effect of decreasing audit's quality. Audit failure affects the quality of the financial analysis that has been carried out and has a big impact on the accuracy of decision making due to the material information bias. Findings of this research will urge the Public Accounting Firm (PAF) to design a quality control of the audit services. This action is taken with the consideration of maintaining the quality of audit services and the reputation of auditors.

Utilizing manufacturing data listed on Bursa Efek Indonesia (BEI), the researchers developed a model to explain the audit failure which is seen from restatement of financial statement in the subsequent period.

This research indicates that audit failure to detect the misstatement will decrease the audit's quality of other companies audited by the same auditor. There is also an insight that contagion effect of decreasing auditor quality was stronger for non-big four and non-industry specialist auditors.

Audit failure still has the potential to occur. There is the potential that a failure in an audit of a particular client entity has an impact on defects of other clients served. If this allegation is proven, there are big challenges faced by the public accounting profession and PAF to pay special attention in order to maintain the professional reputation.

Professional body and government need to develop a robust standard and operating procedures as well as quality control on audit engagement.

Due to the intention of fraud occurred in Indonesia, namely SNP Finance and Garuda Indonesia case. It is important to learn from that cases. This research gives fruitful insights to prevent the same case in the future.

Recent studies have concluded that auditors underreport existing internal control over financial reporting (ICFR) weaknesses. This study aims to assess how effective external auditors are, as independent third parties, at disclosing reliable opinions to the public on the ICFR.

Using a logistic regression, the authors analyzed a sample of 106 US companies classified as large accelerated filers or accelerated filers consisting in 53 companies which restated their financial statements and a control group of 53 companies having “clean financial statements” at any given moment during the research period, between 2005 and 2018.

The results indicate that only 34% of companies with financial statements deemed unreliable have received an adverse ICFR opinion issued by the external auditor during the misrepresentation period or its prior year. The authors also notice that external auditors are somewhat effective in identifying and disclosing red flags to the public that certain companies have internal control (IC) material weaknesses. The results also indicate that the average presence of an adverse IC opinion issued by the external auditor during the misrepresentation period or its prior year for companies with unreliable financial statements is higher than for companies with financial statements deemed reliable.

This study tests if an increase in efforts and disbursements with audit fees are justifiable by external auditors’ issuing effective, reliable opinions and reinforcing a more transparent and ethical capital markets environment, that is, an environment where accurate information is available for stakeholders. If external auditors are negligent in providing a qualitative and independent opinion to stakeholders, the increase of disbursements made with audit fees is less justifiable. Thus, the research has practical implication for auditors as well as standard setters.

This study extends the literature on ICFR by empirically testing whether the public can rely on external auditors’ opinions expressed on Sarbanes–Oxley Section 404 reports.

The purpose of this study is to examine whether the gender of an audit engagement partner (EP) is associated with the quality of the EP’s audit output.

This paper defines a low-quality EP as an EP who leads the audit of at least one client firm that subsequently restates its financial statements, while a high-quality EP is an EP that is not associated with any restatement. Using a sample of 6,082 observations from 2016 to 2020, the study estimates a logistic regression of EP quality on EP gender and control variables.

The results show that female EPs are more likely to be high-quality EPs. With an odds ratio of 1.25, the results imply that female EPs are 1.25 times more likely to be associated with higher-quality audits compared to male EPs.

The results of this study imply that female EPs are more likely to perform high-quality audits, and it supports the assertion that EP gender plays a significant role in determining EP quality. Further studies may apply gender theory to investigate the behavior of female EPs.

The results show that female EPs are more likely to be high-quality EPs. With an odds ratio of 1.25, the results imply that female EPs are 1.25 times more likely to be associated with higher-quality audits compared to male EPs.

The results of this study should be of interest to stakeholders such as audit committees, regulators, investors and creditors, as they provide an indicator for assessing the quality of audits. Moreover, considering the EP’s important role in an audit, the current study extends the existing literature by providing evidence of a relationship between EP gender and EP quality.

This study aims to compare machine learning models, datasets and splitting training-testing using data mining methods to detect financial statement fraud.

This study uses a quantitative approach from secondary data on the financial reports of companies listed on the Indonesia Stock Exchange in the last ten years, from 2010 to 2019. Research variables use financial and non-financial variables. Indicators of financial statement fraud are determined based on notes or sanctions from regulators and financial statement restatements with special supervision.

The findings show that the Extremely Randomized Trees (ERT) model performs better than other machine learning models. The best original-sampling dataset compared to other dataset treatments. Training testing splitting 80:10 is the best compared to other training-testing splitting treatments. So the ERT model with an original-sampling dataset and 80:10 training-testing splitting are the most appropriate for detecting future financial statement fraud.

This study can be used by regulators, investors, stakeholders and financial crime experts to add insight into better methods of detecting financial statement fraud.

This study proposes a machine learning model that has not been discussed in previous studies and performs comparisons to obtain the best financial statement fraud detection results. Practitioners and academics can use findings for further research development.

This study aims to investigate the busy season contagion effects on other clients of the Big 4 auditor’s local office associated with the non-timely (NT) filing(s) by large accelerated filer (LAF) client(s) of the office. Specifically, the authors examine the influence such events have on the audit quality and timeliness of other clients of that office.

Using panel data of annual NT filings of LAF clients between 2006 and 2019, the authors apply the ordinary least squares regression technique to model audit reporting lag (ARL) and the logistic regression technique to model the probability of restatements.

Controlling for audit firm, industry and year-fixed effects, the authors find that a LAF NT filing reduces audit quality and audit timeliness of other clients of the office, as measured by restatement risk and ARL. The impact on ARL is most pronounced on the medium and small clients within the office. The deteriorated audit quality is observed for medium clients.

The results of this study have practical implications for auditors and regulators. They reveal the contagion effect in the auditor’s local office with the NT LAF client. The main limitation of the study is the lack of staffing utilization data to allow for drawing conclusions on causality.

To the best of the authors’ knowledge, this is the first study to document the contagion effect of NT filings of LAF clients conducted at the auditor’s local office level.
