The twelve refereed publications which form the basis of this PhD each deal with the impact of regulatory change on the perceptions and behaviours of key participants. The publications are drawn from three collaborative research projects exploring different aspects of financial reporting, auditing and corporate governance regulation. The first project considered the way in which a new regulatory enforcement body, the Financial Reporting Review Panel interpreted its role and the impact of its actions on preparers and auditors of financial statements. The second project reviewed the developing perceptions of preparers, regulators and auditors following the European Commission announcement that IFRS would be adopted for the consolidated accounts of all EU listed companies with effect from 2005. The third project explores the impact of the re-regulation that followed the Enron and Worldcom scandals. In particular it examines auditor / client financial reporting and auditing interactions and presents evidence on the role taken by the newly empowered audit committee in that process. All of the publications present the results of empirical evidence. While a wide range of research methods are used, interviews and questionnaire surveys dominate. All of the publications are policy relevant and recommendations are made in each paper. Although all the research has been undertaken in a UK setting, the issues are explored within the framework of international literature, and most of the findings and recommendations are of international significance. The first part of this commentary provides an overview of the contribution and quality of the work being submitted. The publications are then located within the broad sweep of regulatory theory to demonstrate the coherence of the submission. Each of the three projects is then considered in turn and the contribution to knowledge of each of the publications is then discussed in detail, and summarised in the conclusion.

A company’s board of directors is ultimately responsible for putting effective corporate governance (CG) structures in place as mechanisms to enhance its accountability to stakeholders. An audit committee (AC), which is a subcommittee of the board, is one component of the company’s CG structures. In South Africa, legislation, the Johannesburg Stock Exchange (JSE) listing requirements, and the King code and report of Governance for South Africa 2009 (King III) deal with the composition and responsibilities of ACs. As the shares of AltX listed companies, which are categorised as high-growth potential, small to medium-sized listed companies, are traded publicly, they are required to comply with the Companies Act and to establish an AC according to the Act’s composition requirements to fulfil mandatory responsibilities. In terms of the JSE listing requirements, AltX listed companies must appoint an AC or explain their reason(s) for not doing so. As the total market capitalisation of AltX listed companies has increased by 87% over the past three years, greater numbers of stakeholder groups are being affected. Since stakeholder groups are protected when companies implement effective CG processes, the purpose of this study is to understand the way in which the AC of an AltX listed company, as an example of a high-growth potential, small to medium-sized listed company, adds value to the company and its stakeholders. Attributes that contribute to the value added by ACs were identified as being the characteristics of AC members; the fulfilment of responsibilities through optimised activities; and the fulfilment of responsibilities by maintaining healthy relationships with the board and information providers. An explorative qualitative case-based research design was applied in terms of which a single AltX listed company was selected according to predetermined selection criteria. Data were collected using individual semi-structured interviews, field notes and company documents. Descriptive open coding techniques were used for data analysis with the findings of the study subsequently being presented in terms of a theoretical framework of the attributes that influence the extent to which the AC adds value. The findings of the study confirm that these attributes of the AC facilitate its ability to add value to the AltX listed company investigated and its stakeholders in terms of enlightened shareholder theory. / Auditing / M.

Abstract in English, Afrikaans and Sepedi / The auditing profession is facing criticism for audit firms being associated with clients with a poor ‘tone at the top’ despite auditors being required to assess a company’s ‘tone at the top’, both prior to and during an audit. A problem arises if, should auditors perform an inappropriate ‘tone at the top’ assessment, they may be associated with an unethical company. Moreover, such an inappropriate assessment may result in an incorrect risk of material misstatement assessment and, consequently, an inappropriate audit opinion on the financial statements of the company. A qualitative research approach and a multiple case study design were used to understand how auditors assess a company’s ‘tone at the top’. An audit partner from six JSE-accredited audit firms and senior inspectors from the IRBA were interviewed. It was found that the participating auditors assess a company’s ethical leadership, ethical culture, the governance role of the audit committee and compliance with laws and regulations when assessing a company’s ‘tone at the top’ while adhering to quality control principles. Despite the participants acknowledging both that ‘tone at the top’ assessments are conducted during the pre-engagement and planning of an audit and that the audit engagement partner is responsible for these assessments, there was a lack of evidence in the audit files supporting these assessments. The study findings may enable audit firms to include guidance in their audit methodologies on ‘tone at the top’ assessments and in documenting such assessments and may also assist the IRBA in providing guidance and training to auditors on ‘tone at the top’ assessments. / Die ouditprofessie staar kritiek in die oë as gevolg van die feit dat ouditfirmas geassosieer word met kliënte met 'n swak “karakter aan die hoof”, ten spyte daarvan dat van ouditeurs vereis word om 'n maatskappy se “karakter aan die hoof” voor en tydens 'n oudit te assesseer. Die probleem is dat indien ouditeurs 'n onvanpaste assessering van die “karakter aan die hoof” uitvoer, hulle met 'n onetiese maatskappy geassosieer kan word. Boonop kan so 'n onvanpaste assessering aanleiding gee tot 'n verkeerde assessering van die risiko van wesenlike wanvoorstelling en, gevolglik, 'n onvanpaste ouditmening oor die finansiële state van die maatskappy. 'n Kwalitatiewe navorsingsbenadering en 'n veelvoudige gevallestudie-ontwerp is gebruik om te verstaan hoe ouditeurs 'n maatskappy se “karakter aan die hoof” assesseer. Onderhoude is met ouditvennote van ses ouditfirmas wat deur die JSE geakkrediteer word en senior inspekteurs van die IRBA gevoer. Daar is bevind dat die deelnemende ouditeurs 'n maatskappy se etiese leierskap, etiese kultuur, die beheerrol van die ouditkomitee en voldoening aan wette en regulasies assesseer wanneer 'n maatskappy se “karakter aan die hoof” geassesseer word terwyl aan gehaltebeheerbeginsels voldoen word. Ten spyte daarvan dat die deelnemers erken dat assesserings van “karakter aan die hoof” uitgevoer word tydens die vooraanstelling en beplanning van ’n oudit en dat die ouditaanstellingsvennoot verantwoordelik is vir hierdie assesserings, is daar 'n gebrek aan bewyse in die ouditlêers wat hierdie assesserings steun. Die studie se bevindings kan ouditfirmas in staat stel om leiding in hulle ouditmetodologieë in te sluit vir assesserings van “karakter aan die hoof” en om sodanige assesserings te dokumenteer, en dit kan die IRBA ook help om leiding en opleiding aan ouditeurs te gee vir sulke assesserings. / Profešene ya go hlakiša e lebane le tshekatsheko ka lebaka la difeme tša tlhakišo tšeo di amanywago le badirelwa ba ‘boikgafo le boetapele bja taolo’ bja go fokola, le ge bahlakiši ba nyakega go lekola ‘boikgafo le boetapele bja taolo’ bja khamphani, bobedi pele ga le nakong ya tlhakišo.
