This research has aims to identify the influence of related party transactions (RPTs) on the comparability of financial statements and audit fees of publicly traded companies in the Brazilian market. Two opposing argument have been consolidate in the literature in relation to RPTs: the first one maintains that related transactions can be used by a group of companies with the aim of reducing costs, sharing resources and even obtaining gain; the second argument, supported by the agency theory emphasizes that these transactions can be used opportunistically to expropriate resources from entites based on the assumption that RPTs can have effect on the quality of accounting information. To this end, the premise was adopted that RPTs can reduce the comparability of financial reports and subsequently increase auditors fees, as comparability helps to improve audit efficiency and accuracy. The cauculation of the comparability measure was performed using the method of similarity of the accounting function by DeFranco et al. (2021), audit fees were collected from the reference form and measured using the natural logarithm, in agreement with the research by Habib et al. (2015) and Al-Dhamari et al. (2018). Regarding transactions with related parties, asset weighted RPTs were adopted (Hasnan et al., 2016; Shin et al., 2019; Jalan et al., 2020) to investigate the relationship with comparability. On the other hand, we chose to use RPTs in their logarithm form (Habib et al., 2015; Pratama, 2018; Ali et al., 2021) to verify the relationship with audit fees. Regard to data analysis, to establish the relationship between RPTs and comparability, the multivariate analysis of quantile regression was adopted, using quantiles 0.25,0, 0.50 and 0.75, in which the lowest, medium and highest levels of comparability are analyzed; in terms of RPTs and audit fees, they were estimated using panel data. The results found suggest that purchase and total RPTs negatively impact the quality of information, as they reduce the comparability of companies that have medium and maximum levels of comparability; moreover, the related sales, purchases and totals transactions are complex and increase the risk of material misstatement, resulting in higher fees. This research contributes to the expansion of the literature, by adding evidence of the relationship between RPTs and the quality of accounting information in the Brazilian context. In addition to bringing complications for investors, analysts and auditors, by indicating that comparability is reduced for companies have average and maximum comparability, harming the decision making process and that sales, purchases and totals RPTs are a risk to the audit process, so they need to be analyzed more accurately. Finally, the findings also provide a warning to standard setters regarding the protection of minority shareholders, as related transactions can be used to obscure accounting information.
