This study was conducted to determine the perception of the chief audit executive as head of the internal audit function, on the internal audit activities that should be performed (current and future) within South African companies after which the findings were compared with the international perception in this regard. Data was also obtained on whether internal audit activities were performed inhouse or were outsourced; the importance of the internal audit activities, senior management’s rating of the value added, the internal audit approach followed, and whether the internal audit standards were being complied with. A statistical analysis was performed on data that was obtained from questionnaires and interviews. This study targeted 30 chief audit executives, and to a lesser extent 30 Chief Executive Officers/Chief Financial Officers/Chief Operating Officers, of large South African listed companies. The results prove that chief audit executives perceive themselves as performing their internal audit activities according to the internal audit Standards and that they satisfy the needs and expectations of their companies. The internal audit profession, its clients and internal audit educators may benefit from the study in the planning of future internal audit activities and educational programmes respectively.

Fraud is an inevitable cost of doing business. Organisations are responding to the pervasiveness of fraud by employing increased fraud risk management strategies. Internal audit is the most effective corporate control available to management to address the threat of fraud. Internal audit as an effective corporate control is studied in the context of the mandatory obligation imposed by The Institute of Internal Auditors’ 2009 International Professional Practices Framework (hereafter, IPPF). This mandatory obligation requires the internal audit function to ‘evaluate the potential for the occurrence of fraud and [to evaluate] how the organisation manages fraud risk’ (IPPF performance standard 2120.A2 Risk Management). At the individual auditor level, the internal auditor is required to ‘possess the knowledge, skills, and other competencies to perform their individual responsibilities’ (IPPF attribute standard 1210 Proficiency). These standards have the potential to increase expectations on the internal audit profession to prevent and detect the threat of fraud. This expectations gap raises two research questions: (1) What are the determinants of auditors’ fraud detection capabilities? and (2) What constitutes expert performance in the fraud detection task? This thesis aims to address these research questions through the performance of two studies. Study 1 used interviews to investigate the determinants of fraud detection capabilities of both the external auditor and internal auditor. Study 2 drew on the results from Study 1 and was an online survey of Australian internal audit practitioners. Study 1 confirmed that the determinants of auditor expert performance in other audit tasks established in literature, namely, certification, continuous learning, practical experience, analytical reasoning, data analysis skills, communication skills, are also applicable to the fraud detection task. Further, the fraud detection task requires key, unique capabilities because fraud has an inherent element of deception and concealment by fraud perpetrators. The determinants of auditor expert performance unique to the fraud detection task include mentoring, technical skills, and the ability to work in a team. An additional finding is the identification of an effective control environment as a determinant related to the environment where the auditor performs audit work. The resulting model of auditor expert performance in fraud detection depicts the relationship of these determinants (independent variables) with expert performance in fraud detection (the dependent variable). The inclusion of new determinants and the revision of the definitions of determinants established in literature provided the solution to Research Question 1. Subsequently, auditor expert performance in fraud detection was defined based on the resulting combination of determinants. This was the solution to Research Question 2. Study 2 was an online survey with new scales of measurement that were developed from Study 1 interview data. Expert studies and pilot studies were conducted to validate these new scales of measurement. The online survey captured the perceptions of Australian internal audit practitioners about the determinants identified in Study 1. The survey data was applied to the model of auditor expert performance in fraud detection. The main findings of this study are: (1) the assessment of the effectiveness of the strategies to develop auditors’ knowledge of fraud and fraud detection - mentoring, practical experience, continuous learning, and certification; (2) the assessment of the effectiveness of each determinant in contributing towards auditor expert performance in fraud detection. The findings of this thesis supported the expectation that the uniqueness of the fraud detection task impacted on the composition of auditors’ fraud detection capabilities and subsequently, the composition and definition of auditor expert performance in fraud detection. The participation of practitioners – internal auditors, external auditors, and fraud investigators - and academics in the data collection and validation processes provided valuable insight into the research design and provided helpful data for the two studies. The main contribution of this thesis is the extension of Bonner and Lewis’ (1990) model of auditor expert performance to the fraud detection task. Next, the resulting model of auditor expert performance in fraud detection provides the internal audit profession, organisations, and the individual internal auditor with an understanding of the factors that impact on the individual internal auditor’s fraud detection capabilities. Therefore, this practical understanding of internal auditors’ fraud detection capabilities has the potential to: (1) contribute to the development and improvement of an organisation’s fraud risk management strategy; (2) inform the policy debate regarding the promulgation of professional and mandatory standards; and (3) contribute to auditing practice and the audit profession through the identification of strategies to educate the audit profession about fraud detection. The final contribution is the research design where the qualitative study (Study 1) contributed to the development of the survey instrument and provided insights into the results of the structural mode (Study 2).

The thesis covers aspects of the law relating to letters of credit. It deals with the operation of letters of credit with particular reference to the doctrine of strict compliance, the principle of independence, the fraud exception and conflict of laws. According to the principle of independence, banks must make payment in terms of the letter of credit irrespective of any dispute that may exist between the buyer and the seller in an underlying contract or other contracts. Although the principle of independence is clearly established, it is not absolute. An exception occurs in the case of fraud. Thus, if the seller has committed fraud, such as tendering forged documents, the buyer can instruct the bank not to make payment in terms of the credit. If the bank refuses to dishonour the letter of credit, the buyer can apply to a court to interdict the bank from making payment. In South African law the buyer must establish that the seller was party to fraud in relation to the documents presented to the bank for payment before the court can grant an interdict. This thesis also examines the standard of proof of fraud required in letters of credit transactions and proposes a standard of proof which will not unduly favour the seller whose good faith is in dispute. The fast growing technology of computers and telecommunications is rapidly changing the methods of transacting business by paper documentation and letter of credit transactions are no exception. At present the buyer can apply to the bank to issue a letter of credit through the computer and banks also communicate letter of credit transactions through computer networks. However, the beneficiary still has to present documents to the bank for payment in paper form. It is proposed that the Uniform Custom and Practice For Documentary Credits (UCP) be amended to provide for fully computerised letters of credit transactions. Another objective of the thesis is to examine the doctrine of strict compliance. In terms of the doctrine of strict compliance documents presented under the credit must comply strictly with the requirements set out in the credit. If banks are satisfied that the documents presented by the seller strictly conform with the requirements of the credit they are obliged to make payment as required by the credit. It is proposed that the doctrine of strict compliance should not be applied strictly. In other words, the banks should make payment in terms of the credit if the discrepancy in the documents is trivial. The thesis also covers conflict of laws issues. As the UCP does not have rules dealing with conflict of laws, most jurisdictions have developed their own rules to be applied by the courts in cases of conflict of laws. The thesis examines the different rules of conflict of laws as developed and practiced by different jurisdictions.
