Divulgações sobre o justo valor por parte das empresas cotadas em Portugal

Abstract

Sendo que a globalização económica levou à adoção das International Financial Reporting Standards (IFRS), o justo valor torna-se cada vez mais relevante e as divulgações sobre o justo valor tornam-se indispensáveis para a sua melhor compreensão. Neste estudo pretende-se identificar o grau de cumprimento das divulgações sobre o justo valor por parte das empresas cotadas em Portugal nas suas demonstrações financeiras consolidadas nos anos 2007 e 2012 e analisar os principais determinantes da sua divulgação. Para tal, construíram-se duas grelhas de cumprimento com os requisitos das divulgações sobre o justo valor das respetivas normas nos dois anos, calcularam-se os índices de divulgação e aplicou-se o modelo de regressão linear. Os resultados indicam que as médias dos índices de divulgação dos anos 2007 e 2012 são 75,81% e 79,95%, respetivamente. Revela-se também que as empresas com maior dimensão e auditadas pelas Big 4 apresentam um maior nível de divulgação. Conclui-se ainda que a dimensão é uma variável robusta para explicar o nível de divulgação e as variáveis ano e setor também são estatisticamente significativas e positivas no nível de divulgação.

Since the economic globalization led to the adoption of International Financial Reporting Standards (IFRS), the fair value becomes increasingly relevant and the disclosures about fair value become indispensable for its better understanding. This study is intended to identify the degree of compliance with disclosures about fair value by listed companies in Portugal in their consolidated financial statements for the years 2007 and 2012 and analyze the main determinants of disclosure. To this end, it was built up two grids of compliance with the requirements of the disclosures about fair value of the respective standards in two years, calculated the disclosure indices and applied the linear regression model. The results indicate that the means of the disclosure indices for the years 2007 and 2012 are 75,81% and 79,95%, respectively. It also reveals that companies with larger size and audited by Big 4 show a higher level of disclosure. It even concludes that the size is a robust variable to explain the level of disclosure and the variables year and sector are also statistically significant and positive on the level of disclosure.
