The purpose of this paper aims to investigate whether the source of audit committee accounting expertise influences the internal audit function (IAF) effectiveness in the Tunisian setting.

In the analysis, the authors conduct a survey of chief internal auditors from Tunisian listed companies. Then, a multivariate regression analysis is performed in order to analyze the relationship between audit committee financial expertise and IAF effectiveness.

The findings of the present study show that audit committee accounting financial expertise is most likely to be positively associated with the implementation of internal audit report recommendations. The authors also find that only financial expertise gained from accounting education and experience (e.g. an audit committee member with experience as a certified public accountant, auditor, chief financial officer or chief accounting officer) is associated with a stronger implementation of IAF recommendations, but not financial expertise gained from work experience in finance positions.

These results may have implications for regulatory bodies. They can provide a better understanding of the role of the audit committee expertise in monitoring internal audit processes. The major contribution of this study is that the audit committee's oversight role is strengthened if the committee members have accounting and auditing expertise.

The study extends prior literature by providing evidence that the source of audit committee accounting financial expertise enhances internal audit effectiveness beyond the outcomes it has on financial reporting quality. The study also contributes to the ongoing debate in the corporate governance literature concerning the definition of the financial expertise of audit committee members.

This study aims to develop a maturity model designed for assessing the current state of digitization in accounting firms.

The authors have developed this index where the maturity levels are defined from the life cycle theory. For the items of a maturity measure, the authors have adopted a multimethodological approach. That approach allows to identify 27 measurement items to cover the three dimensions of audit, reporting and taxation.

This research proposes a diagnostic tool specific to accounting firms. The authors have tested this index in the Tunisian context. The results show that there are two types of accounting firms. This study found the first firm in the embryonic phase and the other in the growth phase. This points out the active role of Tunisian accounting firms in technology integration.

This study highlights the integration of technology in the accounting field. Specifically, it aims to address technology management in accounting firms by measuring the degree of digitization of accounting firms. This research projects the use of information technologies (artificial intelligence, cloud, big data, etc.) in auditing, reporting and taxation.

On a practical level, this research provides an organizational diagnostic tool to assess the status of their accounting firms in terms of digitization. This will motivate practitioners to make frequent assessments, thus contributing to continuous improvement toward digitization.

The theoretical foundation of this research is based on the theory of the life cycle of technologies. This study is using this theory to identify and describe the current phase of the organization. And that is by indicating the overall scores on the technological capabilities of the accounting firms.

The purpose of this paper is to examine whether coordination between external auditors and the internal audit function affect the timeliness of audit reports as proxied by audit delay.

This study uses a survey of chief internal auditors from Tunisian listed companies to analyze the extent of coordination between IAFs and external auditors. Data spanning a four year period (2011-2014) was collected for 53 listed companies. Further, regression analysis was used to test the hypothesis.

Results indicate that greater coordination between internal and external auditors results in timelier financial reporting.

Overall, the study makes several important contributions. Findings provide important insights that an IAF acts as a valuable resource to external auditors. The results should be of interest to managers, external auditors and the Tunisian Financial Market Council.

This paper is one of few studies which have examined the association between internal-external audit coordination and timeliness of audit reports in an emerging market. The study makes a meaningful contribution to the corporate governance literature by investigating the influence of internal audit assistance on the delivery of timely audited financial information to the capital market. Results also have policy implications for Tunisian regulators with respect to the promotion of internal auditing best practices.

The purpose of this study is to examine the relationship between corporate governance and financial soundness of Islamic banks. Precisely, this study examines the Shariah Board’s characteristics and empirically diagnoses its impact on the financial soundness of Islamic banks.

In this case, the level of bank soundness is individually measured using the z-score indicator. Regression analyses are applied to test the impact of the Shariah Board’s characteristics on the financial soundness of Islamic banks, using a panel data set of 67 Islamic banks – covering 20 countries during the period 2005–2014.

The model shows that the size of the Shariah Board has a negative and significant impact on the financial soundness of Islamic banks. However, the Shariah scholar with knowledge in finance/accounting, the presence of Mufti, the interlocked Shariah scholar and the foreign Shariah scholar do not have any significant impact on the financial soundness of Islamic banks.

This study contributes to fill the gaps in the literature that discussed the Shariah Boards’ role in the governance of Islamic banks. In addition, it provides practical implications to the Shariah Boards’ members in the Islamic banks and calls for setting a sufficient number of scholars for each Shariah Board.

With this paper, the authors aim to clarify the relationship between Shariah Board and financial soundness of the Islamic banking, and provide additional insights to the emerging literature of Islamic banking. Contrary to previous research studies, the authors use an additional hypothesis, i.e. the presence of Mufti that has a positive and significant effect on the financial soundness of Islamic Banks. Methodologically, the authors incorporate a new measure to evaluate empirically the impact of Shariah Board members with knowledge of finance and accounting on the financial soundness of Islamic banks.

The purpose of this paper is to investigate whether there is any relationship between the effectiveness of an audit committee and the financial reporting timeliness of Tunisian listed companies as proxied by external audit delay (AD). Analysis focuses on five audit committee characteristics: authority, financial expertise, independence, size and diligence.

Empirical tests address 162 firm-year observations drawn from Tunisian listed companies during 2011-2013.

Multivariate analyses indicate that audit committees with members who have financial expertise are significantly associated with shorter AD. Thus, the results suggest that audit committee financial expertise contributes to the improvement of financial statements’ timeliness.

The audit committee attributes examined in this study were based on DeZoort et al. (2002) framework. There could be other aspects of audit committee effectiveness such as audit committee tenure and audit committee chair characteristics, which were not addressed in the present study. Thus, future research may consider and examine these other components of audit committee effectiveness.

Findings have managerial implications. Companies can re-look into how to further improve audit committee composition in order to enhance the timeliness of financial reporting. The issues of audit committee effectiveness and timely reporting also affect regulators and policy makers since they need to play a role in the establishment of effective audit committees and the improvement of financial reporting timeliness.

This study is one of few that have examined the impact of audit committee effectiveness on ADs in an emerging market country. Findings lend credence to the belief that audit committee members’ financial expertise enhances the quality of financial reporting by firms in a North African market criticized for the lack of maturity of its corporate governance system (Klibi, 2015; Fitch Ratings, 2009).

This paper aims to investigate the association between internal audit function (IAF) characteristics and internal control quality.

Using data gathered from 59 chief audit executives from Tunisian listed companies, this paper uses a regression model to examine research hypothesis related to the association between IAF characteristics and internal control quality.

The findings of the current study reveal that internal control quality is significantly and positively associated with IAF competence, internal audit quality control assurance level, follow-up process and audit committee’s involvement in reviewing the internal audit program and results.

The findings have significant implications for IAF wishing to enhance their effectiveness, by recognizing the impact of the IAF’s characteristics on internal control quality. The findings of this study also have significant implications for regulatory bodies who are concerned with the internal control quality, managers and audit committees who determine IAF investment, oversight IAF activities and assess internal auditors’ performance.

This study helps fill a gap in the extant literature where existing empirical evidence of how the IAF characteristics influences the quality of the financial reporting process in emerging markets is scant.

The purpose of this paper is to better understand the current state of the Islamic financial system in Tunisia. In addition, it is aimed at discussing the preconditions that can help exploit the potential development of Tunisia's Islamic finance and expand the banked population.

The paper describes the regulatory and legal framework governing the Tunisian Islamic banks. It provides a mapping of Islamic banks, mutual funds, Takaful institutions and a potential Sukuk market. The paper also relates recent developments including academic qualifications and training in Islamic finance.

The paper concludes with various recommendations for the successful transition from a niche position to a critical mass. It argues the need to establish a specific regulatory framework, supervisory standards and rules of accounting for this kind of institutions. It suggests the development of Islamic financial education to strengthen the role played by the Islamic financing Ecosystem and to help Tunisia promote local and exportable expertise to other countries. Finally, authorities should focus more on promoting market Sukuk, Takaful and microcredit to fund SME.

This paper contributes to the assessment of the current situation of Islamic finance in Tunisia by performing a full scan of the Islamic financial landscape instead of being limited only to Islamic banks. It proposes some prerequisites to benefit from the opportunities offered by the Islamic finance industry in Tunisia to take advantage of its future potential and ensure its promotion.

The purpose of this paper is to examine the impact of board characteristics and external audit quality on earnings management among major Tunisian banks over the period 2003-2007.

Multivariate regressions are employed to test the effect of board structure and external audit quality on discretionary provisions as a proxy for earnings management.

Results indicate that among the characteristics of the board, CEO duality is associated with higher levels of discretionary provisions. However, the presence of directors affiliated to the largest shareholder tends to constrain earnings management practices. The results reveal also that a co-audit belonging to the BIG 4 provides incentives to manage earnings while the capacity of the external auditor to disclose reservations impacts negatively the manager's discretion.

First, it is not desirable to appoint a co-audit both belonging to the BIG 4. Second, the presence of affiliated directors reduces the discretionary practices except in cases where directors are affiliated to families. In this case, banks should strengthen the presence of independent directors. Finally, the delineation of the leeway left in the Tunisian accounting standards would provide more transparent financial information.

This study contributes to the literature on governance and its impact on earnings management among Tunisian banks by introducing two variables that have not been tested before which are affiliated directors and co-audit. The paper will be of value to banks willing to comply with the Governance Good Practice Guide adopted recently in Tunisia.

The paper seeks to examine income smoothing practices in Islamic banks. It first focuses on detecting income smoothing practices. It then seeks to test whether loan loss provisions (LLPs) are used for earnings management purposes.

The paper explores income smoothing practices on a sample of 66 Islamic banks over the period 2001‐2006 using Beidleman's and Eckel's coefficients. Data are obtained from the Bankscope database. To test the use of LLPs to smooth Islamic banks results, a regression model was developed and tested.

The results provide evidence on an extensive use of income smoothing by Islamic banks. More than 75 per cent of the examined banks have a determination coefficient between 0.5 and 1 and 44 per cent have a variation coefficient less than 0.5. However, income smoothing is not achieved through LLPs. The variable earnings before taxes and provisions are not significant in all model specifications. The paper advances that these smoothed incomes are derived rather by the use of profit equalization reserve (PER) and investment risk reserve (IRR). The finding is contradictory to the widespread view stating that those mechanisms are designed to stabilize rewards attributed to investment account holders.

The non‐disclosure of detailed information on PER and IRR prevented the empirical testing of the assertion on the use of these discretionary items to smooth Islamic banks' incomes.

Unlike previous studies which implicitly assume that Islamic banks intentionally use accounting techniques to disclose smoothed results, this paper pioneers the study on detecting income smoothing practice by such institutions. Second, it explores the use of LLPs for earnings management purposes in the context of a fast growing industry where Islamic assets have grown on average by 30 per cent per year over the period 2002‐2007. Third, it is the first paper to give some evidence on the use of PER and IRR as income smoothing devices. Finally, the paper covers a larger number of Islamic banks and from various countries.

The purpose of this paper is to examine empirically the nature of smoothing returns practices in a sample of 79 Islamic banks across 19 countries during the period 2001‐2006.

Previous researchers' methods, based on the variation and determination coefficients, are used in this study to detect the smoothing practices.

Results indicate that the revenues from the “Shariah‐based products” derived from the profit and loss sharing principle show higher variability than the “Shariah compliant revenues” and that income from this source is relatively lower. They also show that a large number of Islamic banks engage in natural income smoothing. Based on the determination coefficient results, 70 per cent of banks were found to have less smoothed total revenue than their net income. Results based on variation coefficient further confirm this finding, with 67 banks having a coefficient of total revenue higher than that of the net income.

The results suggest that Islamic banks should strengthen the use of smoothing techniques, such as the profit equalization reserves (PER) and the investment risk reserves (IRR), as they allow them to further stabilize the revenues payout for the investment account holders (IAH) and therefore mitigate withdrawal risk. Standardizing the smoothing techniques could be a solution to overcome the variability of this category of revenue.

This work is the first of its kind for Islamic banks. It extends previous research by examining whether or not managers may smooth their results naturally or intentionally. It also helped to bridge the gap in the literature by providing the empirical evidence on the smoothing returns in Islamic finance.
