Using 5,055 sample firm-years in Korea between 2009 and 2013, this paper aims to examine the association between the characteristics of the internal audit and the number of external audit hours as a proxy for audit efficiency.

This study is motivated by the International Standard on Auditing No. 610: “Using the work of internal auditors”. This auditing standard guides external auditors in using the work of internal auditors to obtain audit evidence and consult internal auditors for direct assistance. The authors expect that external audit efficiency will increase when the work of competent internal auditors is used.

The authors find that the number of internal auditors relative to the number of employees is associated with the number of external audit hours. This result suggests that the greater the availability of internal auditors, the greater their contribution will be to the financial statement audit and the more efficient the audit. The authors find evidence that external auditors use the work of internal auditors with accounting and legal expertise to improve audit efficiency. They also find some evidence that the work of internal auditors with greater availability is more effective during initial external audit engagements.

This study adds to the extant literature on the contributions of internal auditors to external audits by using archival data and by measuring audit effort using a large database of audit hours. In addition, our findings have practical implications for firms and external auditors who are evaluating the role and value of using the work of internal auditors. The authors also believe that the findings will be of interest to regulators or auditing standards boards.

The purpose of this study was to determine current practices for two salient aspects of the audits1 of listed South African long‐term insurers by empirically analysing prevailing practices. First, current practices for the composition of the audit teams responsible for these audits are determined. Thereafter current practice is determined for the proportion of audit time spent by the different specialists on audit teams on the audit of the high‐risk components of policy liabilities and the related earnings. When allocating audit staff and establishing continuing professional development plans for staff the auditors of all listed and unlisted South African long‐term insurers could use the findings of the study as benchmarks.

Highlights the role played by the Securities and Exchange Commission (SEC), the New York Stock Exchange (NYSE), the American Institute of Certified Public Accountants (AICPA), The Institute of Internal Auditors (IIA), the Treadway Commission, and other professional organizations in furthering the establishment of audit committees in the USA. In the international arena, the UK Cadbury Committee, the Australian Borsch Committee, and the Canadian Macdonald Commission have influenced the widespread use of corporate audit committees in their respective countries. The guidelines on audit committees set by the IIA, AICPA, SEC, and the Treadway Commission have had a tremendous impact worldwide. Cultural differences may, however, limit the formation and effectiveness of audit committees globally even though auditing is a relatively homogeneous profession. The Institute of Internal Auditors, as an international professional association, may wish to consider the cultural dimensions of corporate governance in formulating professional internal auditing standards dealing with the structure and functions of audit committees internationally.

The purpose of this paper is to demonstrate the relationship between internal audit functions (IAF) and financial reporting quality (FRQ) and whether such a relationship is moderated by senior management support (SMS) in listed companies in Nigerian Stock Exchange (NSE).

This research is a cross-sectional study, using primary data in the form of a survey sent to 175 listed companies in NSE. A total of 149 questionnaires have been collected and analysed out of which 97 were found to be useful and used in the final analysis.

The findings indicate a positive and significant relationship between internal audit qualities of work performed, internal control activities, coordination between internal and external auditors and FRQ and this finding was also supported by SMS as a moderator. However, the results show a negative and insignificant relationship between internal audit competency, organisational status and FRQ.

The findings support the assumption with regard to agency theory. The board should support the IAF to serve as an effective monitoring mechanism in minimising opportunistic management actions. Regulators should also ensure adequate structures that will strengthen the organisational status of the internal auditors to perform towards improving FRQ.

The study contributes to the existing literature by assessing the effect of IAF on FRQ as moderated by SMS.

This study examines the effects of incentive compensation and guanxi, a type of informal personal relationship between people, on the objectivity of Chinese internal auditors. Given that the objectivity of internal auditors is essential for promoting financial reporting quality, it is important to investigate the effectiveness of internal audit functions, especially in emerging markets where the corporate governance mechanisms designed to promote objectivity are less mature.

The research employs a 2 × 2 between participants experiment with 116 graduate accounting student participants.

After controlling for internal auditors’ ethicality, we find that close-guanxi between management and internal auditors and incentive compensation in the form of bonuses based upon meeting earnings targets both have the capacity to impair the objectivity of Chinese internal auditors. Participants were more tolerant of management’s attempts to manage earnings when there was close guanxi or bonus compensation. Further, compensation structure only influenced internal auditors’ support of management when guanxi was distant, but when there was close guanxi between internal auditors and management, internal auditors were unlikely to challenge management regardless of the compensation structure.

Based on 1,798 firm-year observations from 2009 to 2013, using publicly available disclosure data for Korean listed firms, this study aims to examine whether statutory internal auditors influence firm-level stock price crash risk.

Based on the bad news hoarding theory of crash risk, the authors investigate the association between the quality of statutory internal auditors and one-year-ahead stock price crash risk. The quality of statutory internal auditors is measured as the compensation of statutory internal auditors and the financial expertise of statutory internal auditors. Stock price crash risk is measured as an indicator variable whether a firm experiences one or more crash weeks during the fiscal year period.

The authors find that higher quality of statutory internal auditors – measured through greater compensation and greater financial expertise – is associated with lower possibilities of future stock price crash risk. These results indicate that high-quality statutory internal auditors mitigate bad news hoarding of managers because of their greater capability and stronger incentive to lower litigation risk and preserve their reputation. The results are mostly robust to different measures for stock price crash risk and the quality of statutory internal auditors.

The findings of this study regarding stock price crash risk are important for investors because such risk can significantly affect investor welfare. The results indicate that statutory internal auditors play an important role in controlling future stock price crash risk and maintaining stability in the equity market.

This study adds to the extant literature on the determinants of stock price crash risk and is the first to examine the impact of internal auditors on stock price crash risk. Moreover, this study also contributes to the existing literature on internal auditor quality by showing that high-quality statutory internal auditors reduce risks in financial markets.

The purpose of this paper is to analyze whether internal audit (IA) influences the successful implementation of the International Financial Reporting Standards (IFRS). From January 2017, listed companies in Saudi Arabia have been mandated to adopt the IFRS. Conducted in the 2014–2016 years before this deadline, the study investigates the readiness of IA departments in the Kingdom to adopt the IFRS in their totality, as required, by January 2017.

Data were collected for the period 2014 and 2016, two years after the announcement of the intended adoption of the standards, and hence, two years into the five-year preparation period. Data obtained from 78 chief internal auditors from listed companies in Saudi Arabia, and the extraction of information from companies’ annual reports.

Results of regression analysis show a significant association between the readiness for IFRS adoption and IA size and IA staff training. In firms that adopted the IFRS in the period before the mandatory implementation, IA is weak in the role of monitoring. In this connection, it is demonstrated that the adoption and implementation of the IFRS are likely to be more effective when IA reports directly to the audit committee rather than to management. Further, the results reveal that the Hausman test is not significant for the IA characteristics. Hence, there is implication that the measurement instruments used in the study are exogenous and do not associate with the error term.

The new insights into the impact of IA on IFRS adoption, gained from studying this issue within the oil-based Saudi Arabian economy, represent a contribution to the IA literature. The results of this study provide new insights to several stakeholders. First, to academia, which can benefit from new IA knowledge and understanding in the specific context of the Kingdom of Saudi Arabia (KSA), which can be representative of the Gulf region and the wider Arab World. Second, to policy-makers and practitioners in the KSA and other Middle-Eastern, Asian and developing countries that share similar cultural predispositions, socio-economic institutions and/or general socio-economic environments. Additionally, it offers insights for small- to medium-sized companies that have not thus far, adopted the IFRS.

Based on 3,775 firm-year observations from 2009 to 2013 using publicly available disclosure data for Korean listed firms, this study examines whether and how firm-level governance characteristics are associated with investment in internal auditing proxied by compensation and the number of statutory internal auditors.

The authors investigate the association between governance characteristics and investment in internal auditing proxied by compensation and the number of statutory internal auditors.

The authors find that firms with greater ownership of the largest shareholders and with a higher proportion of outside directors invest more in internal auditing. These results indicate that firms with higher incentive and demand for monitoring are more likely to invest more in internal auditing. The authors further find that the positive effect of the largest shareholder ownership (board independence) on investment in internal auditing is attenuated in firms with greater board independence (ownership of the largest shareholders) suggesting that the complementary effect of the two governance mechanisms associated with internal auditing weakens as they function simultaneously.

The results provide regulators and investors with a clear picture of the governance characteristics of firms associated with investment in internal auditing. The results imply that both the largest shareholders and the outside board of directors play a significant role in resource allocation in internal auditing within a firm. The effect of allocation, however, can be attenuated contingent upon the combined characteristics of governance mechanisms.

Using large amounts of public archival data, this study adds to the extant literature on firm characteristics associated with investment in internal auditing. This study also contributes to the literature by expanding the scope of research on executive compensation to the locus of statutory internal auditors.

This paper aims to investigate the impact of family involvement in ownership and governance on the quality of internal auditing.

Leveraging a hand-collected data set of listed family firms from 2014 to 2020, this study uses regression analyses to investigate the impact of family ownership, family involvement on the board, family CEO and the generational stage of the family business on the quality of internal auditing.

The results provide evidence that family ownership is positively associated with the quality of internal auditing, while later generational stages of family businesses have the opposite effect. Additional analyses reveal that the presence of a sustainability board sub-committee moderates the relationship between generational stages of family businesses and the quality of internal auditing function.

This paper does not consider country-institutional factors and other potentially family-related antecedents or governance factors that may affect the quality of internal auditing.

The results are informative for investors and non-family stakeholders interested in understanding under which conditions family-related factors influence the quality of internal auditing functions.

This study offers fresh evidence regarding the relationship between family-related factors and the quality of internal auditing and board sub-committees that moderate such a relationship in family businesses.

The purpose of this study is to examine the effects of internal audit function (IAF) quality on the operational efficiency of Chinese firms.

The authors use regression models with a sample of Chinese listed companies to test their research hypotheses.

The authors find that IAF quality is positively associated with firm operational efficiency. The result is unchanged after correcting for endogeneity via the instrumental variable method and using an alternative measure of firm operational efficiency. The authors show that IAF competence improves firm operational efficiency, but the relationship between IAF independence and firm operational efficiency is insignificant. Additionally, they find that IAF quality can only significantly improve firm operational efficiency in the presence of effective corporate governance at the firm level and strong institutions at the province level. Using path analysis, the authors find that an IAF can improve firm operational efficiency directly or indirectly by promoting firm internal control quality.

The findings of this study suggest the need for a balance between IAF competence and independence to achieve the goals of IAF. Additionally, the authors study suggests that the effectiveness of IAF is contingent on corporate governance and market-based institutions.

The study’s findings contribute to the burgeoning literature on the relationship between IAF and firm operational performance and deepen the authors’ understanding of the role of IAF in an emerging economy whose government plays a major role in promoting and enforcing internal audits. The study also empirically support the Internal Audit Governance Maturity Model proposed by the Institute of Internal Auditors.
