Význam vnitřního kontrolního systému pro statutární audit

The diploma thesis deals with the internal control system, its individual components from the point of view of the COSO framework and the audit procedures that the external auditor should follow during the execution of the contract. The purpose of this thesis is to apply theoretical knowledge on a practical example. The aim of my diploma thesis is to perform audit procedures on model company specifically on the areas of the internal control system and assess whether it does not contain significant deficiencies and whether it is able to prevent fraud. The statutory audit is performed on the basis of the recommended methodology which is issued by the Chamber of Auditors of the Czech Republic itself. The necessary data about the functioning of the internal control system were obtained by physical presence inside the company and on the basis of interviews with selected individuals. From the resulting investigations it was found that the internal control system of the selected accounting unit is set up in an appropriate way and the auditor can fully rely on it during the performance of the audit engagement.
