A determinação da materialidade no planejamento e nos processos de auditoria externa das firmas de Belo Horizonte

Abstract

The existence of large accounting scandals in the last decades has increased the lack of confidence in the financial information provided by the administrations regarding legal and realistic procedures. With this, the audit gained space and was reinvented, by legal impositions and by interests of investors. The audit applies procedures to obtain sufficient evidence to justify your opinion. The extent of these tests depends on the determination of materiality. The determination of materiality is an activity of the audit planning that requires the professional judgment of the auditor, however, with the advent of the Brazilian standards for auditing to the international auditing standards, the quantification and documentation of the determination of the materiality became a rule. This leads us to question how external audit companies set what is material and relevant in their audit procedures. Therewith, the main objective of this labor is to compile the ways for the determination of the materiality and to point out the most usual ones by the external audit market in Belo Horizonte. The research embrace 29 independent audit companies established in this city, registered in the CVM through their technical officers. For that, the deductive method was used, starting from a broader model, guiding the quantifications of the materiality, for particular models, the guidelines of each audit company. The observational, comparative and statistical method for this research was observed. Bibliographic research and a vast amount of legislations, normatives of the CFC and IFAC were used. The instrument for data collection has consisted in the form application. It is characterized as a descriptive research, which raises and analyzes the application of the materiality on the audit of the financial statements used by the researched population and correlates them with the theoretical basis of the Brazilian and international auditing standards elaborated and adapted by the CFC. The results of the research indicate that, in general, based on the data analysis, that the external audit companies in Belo Horizonte comply with the requirements of the NBC TAs and ISAs for the determination of the materiality, however, not in their entirety.
