This study aims to verify, in the light of CPC 25—Provisions, Contingent Liabilities and Contingent Assets, how the company Samarco Mineração S.A. treated its financial statements, the provisions and contingent liabilities arising from the environmental disaster that occurred on November 5, 2015, with the disruption of the Fundão dam in Minas Gerais. The research is descriptive, with documentary procedures, since the company's financial statements were analyzed, including the explanatory notes. As a data collection instrument, a checklist was used containing the main points required by CPC 25, in order to facilitate the reading of the statements, and allowing the comparability of data between the publications of the three years selected as a sample, 2015, 2016 and 2017. The results revealed that the adherence to the company's financial statements, with regard to the recognition, measurement and disclosure of the provisions and contingent liabilities resulting from the accident corresponds to 74.3%, on average, of what is required by the standard, for the three years addressed. Gaps were identified in some main points required by the standard, such as the measurement, which, due to the high degree of uncertainty of the facts resulting from the disaster, the estimates of probable losses and the disclosure of possible losses, were not adequate to represent the disbursement necessary to settle the obligations.
