A presente dissertação teve como objetivo analisar a relação existente entre as Imparidades dos Créditos Concedidos e a Manipulação dos Resultados, visto que esta questão tem sido bastante discutida na literatura ao longo dos anos. Posto isto, de forma a analisar esta relação, o objeto de estudo foram bancos em Portugal. O período de análise do estudo está compreendido entre os anos 2005 e 2019, sendo que todos os dados foram retirados dos seus respetivos sites, da Comissão do Mercado de Valores Mobiliários (CMVM) e do Banco de Portugal (BP). O estudo teve como base 10 bancos, contando com cerca de 103 observações. Primeiramente, foi utilizado o modelo de Jones (1991) modificado por Ugbede et. al. (2013) para o setor bancário. Este modelo foi utilizado para calcular os accruals discricionários, que nos forneciam os valores da manipulação de resultados. Depois de obtidos os accruals discricionários, foi utlizada uma regressão linear para calcular a relação entre as imparidades e a manipulação dos resultados. Tendo em consideração os resultados obtidos através da regressão linear, e após a análise dos mesmos, foi possível verificar que existe uma relação significativa entre as variáveis em estudo, validando assim a hipótese de investigação.

Having said that, in order to analyze this relation, the object of study were banks in Portugal. The study analysis period is between 2005 and 2019, and all data were taken from their respective websites, the Securities Market Commission (CMVM) and Banco de Portugal (BP). The study was based on 10 banks, with about 103 observations. First, it was used the Jones model (1991) modified by Ugbede et. al. (2013) for the banking sector. This model was used to calculate discretionary accruals, which provided us with the values of the manipulation of results. After the discretionary accruals were obtained, a linear regression was used to calculate the relation between the parties and the manipulation of the results. Considering the results obtained through linear regression, and after their analysis, it was possible to verify that there is a significant relation between the variables under study, thus validating the investigation hypothesis.
