In this study, I use Section 404(b) of the 2002 Sarbanes-Oxley Act as an exogenous shock to examine the effect of auditors’ assessment of internal control over financial reporting (ICFR) on audit fees, cost of debt, and net value of compliance between 2002 and 2010. Using firms themselves as their own control, this study conducts firm-fixed effects analyses to explore the close causal effect of SOX 404(b) on compliance costs (proxied by audit fees), compliance benefit (proxied by cost of debt) and net compliance benefit (proxied by Tobin’s q). Through analyzing how SOX 404(b) affects firms’ compliance cost, compliance benefit, and net compliance benefit, the results suggest that SOX 404(b) decreases firms’ cost of debt, but also imposes compliance costs. Overall, SOX 404(b) increases firm value premium by around 8.63%. The study also examines whether the 2007 reforms have achieved their purpose by comparing audit fees before and after the 2007 reforms.

When economic crime is discovered it tends to result in solutions that strengthen the audit. In 2010 a law was adopted which reduced the influence of the audit. The reform gave the smallest companies the opportunity to actively refrain external audit. That can be seen as remarkable as the auditors are the primary control organ of smaller companies. The reform was introduced to simplify the administrative burden and reduce its costs. This qualitative study aims to explain the factors that have been affected by the abolition of auditing based on the auditors' perspective. By answering the research questions: What are the effects caused by the elimination of auditing requirements for smaller companies from the auditor's perspective? What does the financial crime look like in these companies and what factors affect the auditors' decision-making regarding eco-crime? What affects individuals' inclination to commit financial crime? The aim of this study is to chart the factors that have been affected by the elimination of auditing for small companies from the perspective of auditors. Furthermore, the study aims to increase the understanding of the interplay between company stakeholders, small companies and auditors, as there is currently no qualitative research in this area. The research questions are answered using collected secondary data and qualitative interviews. The conclusion of the study suggests that the abolition meant that business leaders without the necessary skills now produce the annual report and the current accounts. Further effects that have arisen are that authorities have increased workload due to both poor annual reports and that audit work has to some extent been shifted from auditors to government agencies. The bolition has also resulted in an increased incidence of economic crime. The factors that affect he auditors' inclination to report criminal acts are primarily; transaction size, the individual's wareness of the crime, the motivation behind it, the customer's inclination to remedy the act and the parties concerned by the action. The study indicates that there is a correlation between the existence of financial crime and high frequency of cash handling. The factors that influence an individual to commit crimes are corporate culture. In the companies where employees commit financial crime, mainly lack of internal control is seen as the reason.
