Audited financial statements are the most substantial source of information concerning bank loan decisions, and investors mainly base their investment decisions on the financial statements in combination with the audit report. The financial crisis brought attention to the existing expectation gap between auditors and stakeholders. An attempt to narrow the gap has been done by IAASB. The new standards require auditors to provide additional information in the audit report. The purpose of the study is to investigate how the extended audit report is perceived by Swedish bank directors. The study has a quantitative research strategy with an experimental design. The experiment includes one control group and seven experimental groups, and the participating Swedish bank directors amounted up to 122. An ANCOVA is performed to test the research questions regarding the bank directors’ perceptions and decisions. The empirical findings and analysis reveal that the disclosure of the assurance level has a positive impact on bank directors’ confidence in the financial statements, perceived quality of the audit report, perceived value of the information the audit report contains, as well as the probability of granting a credit. The results also indicate a significance for key audit matters (KAM) regarding the perceived value of information, meaning that the disclosure of KAM improves bank directors’ perceptions of the informational value the audit report contains. The disclosure of the materiality level does not appear to have a significant impact on the extending of the audit report, implying that a disclosure of the applied materiality level may not be beneficial for bank directors’ perceptions and decisions.

The aim of the thesis is to analyze the substantive tests focused on revenue of selected companies and to evaluate identified risk areas. This thesis is divided into two parts. The first, theoretical part contains the definition, aim, function and types of audit. Then the auditing legislation is defined and the profession of auditor is presented. At the end of the first part, the phases and activities that are performed during the audit of the financial statements are described. The first part is completed by a short chapter dedicated to the forensic audit. The second part is devoted to practical application. Firstly, the selected companies are shortly presented and consequently a materiality level is set for each of them. Then, the level of the internal control system is assessed and the audit risk determined. After that, external and internal risk areas, that may affect reported revenue, are identified. Finally, the impact of identified risk areas on the audit risk and the possible adjustment of the materiality levels are assessed.
