Abstract

The Accounting Pronouncements Committee - CPC was created through Resolution of the Federal Accounting Council - CFC n. 1055/2005 and its main function is the issuance of accounting pronouncements with the objective of harmonizing Brazilian Accounting Standards to international standards - IFRS. In the academic area, several studies have emerged after the adoption of international standards, highlighting the effect of applying these standards on some accounting instrument. In this context, this article aimed to identify the number of audit opinions with qualifications and emphasis paragraph after IFRS implementation in the first two years. Specifically, it was intended to verify if the number of opinions of the companies audited by a BIG FOUR was greater in relation to other auditing firms not belonging to this group. National publicly traded companies on the BM&F BOVESPA, except insurance companies and banks, were surveyed in the period from 2008 PRE IFRS to 2011 POST IFRS, referring to the adoption of standards that came into force in 2010, through Law n. 11638/2007. The research was developed by a descriptive and inferential statistical study whose qualitative variables were the type of opinions issued with reservation, without reservation and denial of opinion, type of auditors BIG FOUR and NOT BIG FOUR, which were described by their absolute and relative frequencies and which were then compared across four years using CHI SQUARE (X2) hypothesis tests. The results found through the statistical tests were that opinions without reservations were more frequent in all years, however, only in 2010 were opinions with reservations more frequent in the other years, and the negative opinions appeared only in 2011. frequency with BIG FOUR has been lower over the years, mainly from 2010 onwards, the opinions with reservations were more frequent by BIG FOUR companies.
