The faith in financial reporting quality and the corresponding auditing process has suffered a lot within the last decade, due to significant accounting scandals (e.g. Enron, WorldCom, Parmalat, etc.). As an answer to these accounting scandals, the law-makers in Germany and the European Union, respectively, have strengthened audit regulations in order to improve the quality of the conducted audits. The aim of this cumulative dissertation is to provide empirical evidence on the effects of intended and already implemented regulative audit requirements in Germany. ln order to consider the wide range of different audit requirements, the dissertation is based on four different study manuscripts, highlighting various perspectives with regard to the appointment, duration, and remuneration of a statutory auditor in the German audit environment. Besides the empirical evidence for separate auditing issues, this dissertation is also aimed to provide a solid theoretical background and critical suggestions for future research.:I.

Audit quality (AQ) is value-relevant if the information is capable of making a difference in the decisions taken by various stakeholders. Therefore, the provision of non-audit services (NAS) to clients, and auditors can create economic bonding and self-review threats that compromise independence and AQ (Friedrich & Quick, 2023). The study investigates the effects of NAS on AQ in the Nigerian insurance industry. The ex-post facto research design was adopted and data were sourced from the annual reports of the 22 insurance companies listed on the Nigerian Exchange Group (NGX) between 2015 and 2020 and sampled through a filtering method. The study used descriptive statistics, correlation matrix, and binary regression techniques to test the formulated hypotheses. The study made use of a binary logistic econometric approach because the dependent variable is a dummy variable assuming the value of "1" and "0". In agreement with the study of Pappert and Quick (2022), the regression results revealed that the provision of NAS, audit fees, and firm size significantly affect AQ in the Nigerian insurance industry, while auditor tenure had an insignificant effect on AQ. The study recommended that the provision of NAS should be strengthened and monitored to align with the list of services that auditors are not prohibited from rendering to the client.
