Abstract(s)
Tem-se vindo a verificar um aumento dos requisitos exigidos por parte dos utilizadores do relatório de auditoria, sobretudo na partilha de mais informação por parte dos auditores. Deste modo, os reguladores têm vindo a promover alterações de forma a contrariar esta tendência. Uma dessas alterações ocorreu com a introdução das Key Audit Matters (KAMs) que são as matérias que o auditor considerou mais significativas no decorrer da auditoria e que têm como objetivo melhorar o valor informativo e a confiança nos relatórios de auditoria.
O período em análise engloba a fase de transição entre o antigo modelo e o novo modelo introduzido pelos reguladores. A amostra é composta por empresas do IBEX-35 e PSI-Geral. Escolhemos estes dois índices, uma vez que as empresas portuguesas adotaram este novo modelo de relatório de auditoria no ano de 2016, servindo as empresas do IBEX-35 como grupo de controlo. Os resultados evidenciam que os honorários dos auditores não sofreram alterações, revelando que os mesmos não variam consoante o número de KAMs divulgadas nos relatórios. Conclui-se ainda que a dimensão do cliente, o Cash Flow Operacional (CFO) e o facto de a empresa auditora ser uma BIG4 influenciam os honorários dos auditores. Estes resultados sugerem que apesar das mudanças implementadas nos relatórios de auditoria e do possível aumento da carga trabalho e tempo necessário para a elaboração do relatório de auditoria, os honorários dos auditores mantiveram-se inalterados, resultados esses que corroboram os obtidos por Bédard et al. (2018).
Due to the constant requirement from the audit report users to provide more relevant information, regulators have been promoting some changes in the audit report. One of these changes occurred with the adoption of Key Audit Matters (KAMs), which are the matters that the auditor considered most significant during the audit and whose objective is to improve the informative value and confidence in audit reports. As this is a relatively recent change, there are few studies focusing on the possible effects of the introduction of KAMs on auditors? fees. For that reason, the aim of this study is to investigate the potential effects of this change on audit fees. The period analyze includes the transition phase between the old model and the new model introduced by regulators. Therefore, the sample includes companies listed in the IBEX-35 and PSI-Geral, however in the period under analysis only the companies listed in the PSI-Geral adopted the new model of the audit report. The results show that the size of the client, the Operational Cash Flow (OCF) and the fact that the audit firm is a BIG4 influence audit fees. Regarding the impact of the introduction of the KAMs, results show that the KAMs do not have any impact on audit fees, suggesting that despite the changes implemented in the audit reports and the possible increase in the workload and time required for the preparation of the audit report, the audit fees remained unchanged, which corroborates the results obtained by Bédard et al.
