Determinantes das despesas com serviços de auditoria e consultoria prestados pelo auditor independente no Brasil

Abstract

The aim of the present study is to identify the factors affecting the auditing and consulting expenditures in Brazilian public companies. The current study was motivated by the lack of studies on auditing and consulting expenses in Brazil, whereas this matter has been researched for years in other countries. Data on Brazil are scarce because the disclosure of spending on auditing and consulting services provided by independent auditors only became mandatory in 2009. The disclosure of these data enables the analysis of the drivers of the fees paid by companies for these services. In this study, we only analyzed the expenditures for consultancy services provided by the same auditing firm; that is, we ignored all spending on other consultants. The results indicate that audit fees are positively related to company size, corporate governance quality, and the Big Four status of the auditor. In terms of consulting expenses, there is a positive relationship between company size and Big Four status, but there is no significant relationship with corporate governance.

Determinantes dos Honorários de Auditoria: um Estudo nas Empresas Listadas na BM&FBOVESPA, Brasil

“…These results reinforce the explanatory power of this variable and corroborate previous research (Simunic, 1980;Palmrose, 1986;Brinn et al, 1994;Joshi & AL-Bastaki, 2000;Köhler & Ratzinger-Sakel, 2012;Hallak & Silva, 2012, Hassan & Naser, 2013Kwon et al, 2014).…”

“…Bortolon, Sarlo and Santos (2013) observed a negative relationship between corporate governance and auditing costs, suggesting that better governance practices have reduced the external audit risks, leading to lower charges. Hallak and Silva (2012) found that companies with better corporate governance levels spend more on audit.…”

“…There is mandatory disclosure of fees in Brazil since 2009, when data used in the only research so far carried out in the country on the subject first became available (Hallak & Silva, 2012). Thus, it seeks to answer this question: which are the determinants of audit fees paid by Brazilian companies?…”

Honorários de auditoria e Book-Tax Differences

“…O tamanho da empresa pode ser um fator de interferência na precificação dos honorários, já que grandes companhias possuem operações mais complexas, que exigem maior esforço e mais horas do profissional de auditoria (Simunic, 1980;Francis, 1984;Hallak & Silva, 2012;Castro, Peleias & Silva, 2015; Borges, Nardi & Silva, 2017).…”

“…Essas empresas possuem mais recursos para o desenvolvimento do trabalho de auditoria, maior nível de especialização, maior competência e melhor reputação no trabalho de auditoria, por isso, cobram honorários mais caros por essa diferenciação na prestação de serviço (Francis, 1984;Yatim, Kent & Clarkson, 2006;Hallak & Silva, 2012;Castro et al, 2015; Borges et al, 2017).…”
