It is worth noting that convergence of Brazilian accounting standard to international accounting standard (IFRS) started in 2007. This convergence occurred in two stages, the first phase in 2008 and the second in 2010. Therefore, it is conjectured that the economic and financial representation of the Brazilian firms may have changed. In other words, the change in the financial representation of firms may entail a change in the managerial process of managers, analysts and other interested users in accounting information. These financial ratios are commonly examined by analysts, investors and other users of accounting information. As a result, the aim of this research is to investigate whether there are significant changes in economic and financial ratios calculated from financial statements due to changes in accounting standards. Eleven economic and financial ratios, segregated into four groups (Liquidity, Debt, Profitability and Value), were chosen in order to show the changes arising from the change in the accounting standard. However, such comparison is examined using data from Brazilian accounting standard in force until 2007 to forecast data from 2008 to 2012. Then, this projection is compared with the accounted numbers by the new accounting standard from 2008 to 2012. Furthermore, this study seeks to analyze the results at an individual level (firm by firm), at a general level (for the set of firms), and at an industry activity level. In the methodology, it were used the time series model (SARIMAX) and the structural break forecast test of Chow (1960). Moreover, four macroeconomic variables were considered in order to control effects from the economy. The main results of this study show a structural break in the representation of Debt ratio of Brazilian companies which were affected by the change in treatment of leasing as stated in CPC 06. Moreover, this study did not found any other structural break due to the new accounting standard in any other representation of financial-economic ratios. Analysis by sector showed evidence that only those sectors affected by intensive leasing operations presented a structural break.
