Resumo: Throughout the years, the need for more relevant information led standard setters to reform the audit reporting model and, consequently, to introduce key audit matters' (KAM) disclosure. In this study, I investigate whether this additional disclosure has an impact on investors' reactions, audit quality, and audit fees. In order to achieve this, my sample includes data from listed companies from the main stock market indices of each European Union's country, from the two years after the transposition date of the requirements of Regulation nº. 537/2014 to the national legislation of each state member. To study KAM's disclosure effect on investors' reactions I use the association studies, the price model and return model, and an event study, the CAR model. For the audit quality's study, I use as proxy the discretionary accruals, while for audit fees I used the natural logarithm of audit fees. The results reveal that KAM's disclosure has no impact on investors’ reactions, audit quality and audit fees. The results find for investors' reactions might result of investors already be aware of the risks disclosed in KAM or because they believe that the auditor performed the necessary work to mitigate the disclosed risks. Audit quality' results may be driven from a lack of impact in the time resources and audit effort needed, while the results for audit fees might result of auditors absorbing any additional time or audit effort related to KAM's disclosure.

Neste estudo, investigo se esta comunicação tem impacto nas reações do investidor, na qualidade de auditoria, e nos honorários de auditoria. Para isso, a minha amostra inclui dados de empresas cotadas dos principais índices bolsistas de cada país da União Europeia, dos dois anos após a data da transposição do Regulamento n.º 537/2014 para a legislação nacional de cada estado membro. Para estudar o impacto da comunicação das MRA nas reações dos investidores utilizo estudos de associação, "price model" e "return model", e um estudo de evento, o "CAR model". Para o estudo da qualidade de auditoria, utilizo os acréscimos discricionários, e para o estudo dos honorários de auditoria utilizo o logaritmo dos honorários de auditoria. Os resultados mostram que a comunicação da MRA não tem impacto nas reações dos investidores, na qualidade de auditoria e nos honorários de auditoria. Os resultados para as reações dos investidores podem advir de os investidores já estarem informados dos riscos incluídos na KAM ou porque acreditam que os auditores realizaram o trabalho necessários para os mitigar. Os resultados para a qualidade de auditoria podem resultar da ausência de impacto no tempo e esforço de auditoria necessários, enquanto que os resultados dos honorários de auditoria podem derivar de os auditores absorverem qualquer tempo e esforço de auditoria adicional.2022-01-17T13:16:16Z2021-12-20T00:00:00Z2021-12-202021-11info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10071/24128TID:202834700engCarvalho, André Ricardo Marquesinfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2023-11-09T17:43:58Zoai:repositorio.iscte-iul.pt:10071/24128Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T22:20:48.462352Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
