Impacto de mudanÃas em padrÃes contÃbeis em medidas de desempenho de firmas: evidÃncias no Brasil / Impact of changes in accounting standards in firms of performance measures: Evidence in Brazil

Andrà Aroldo Freitas de Moura 12 March 2014 (has links)
CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel Superior / A convergÃncia do padrÃo contÃbil brasileiro ao padrÃo contÃbil internacional deu-se a partir do ano de 2007. Esta convergÃncia ocorreu em dois momentos, a primeira fase em 2008 e a segunda fase em 2010. Portanto, conjectura-se que a representaÃÃo da situaÃÃo econÃmico-financeira das firmas brasileiras pode ter se alterado. Ou seja, a representaÃÃo contÃbil dos fatos e fenÃmenos pode ter mudado e isto pode ter afetado o processo decisÃrio de gestores, analistas e outros usuÃrios da informaÃÃo contÃbil. Tais decisÃes sÃo baseadas em indicadores econÃmico-financeiros utilizados por analistas de mercado, investidores e demais usuÃrios da informaÃÃo contÃbil. Portanto, o objetivo desta pesquisa à investigar se hà alteraÃÃo significante nos indicadores econÃmico-financeiros, calculados a partir de informaÃÃes contÃbeis, devido a alteraÃÃo do padrÃo contÃbil brasileiro. Foram elencados 11 indicadores econÃmico-financeiros segregados em quatro grupos (Liquidez, Endividamento, Rentabilidade e Lucratividade, e Valor) que pudessem retratar as mudanÃas oriundas da mudanÃa de padrÃo contÃbil. Tal comparaÃÃo à realizada pela projeÃÃo da sÃrie temporal dos indicadores apurados em padrÃo contÃbil brasileiro vigente atà 2007 para o perÃodo de 2008 atà 2012 confrontando-os com aqueles efetivamente apurados de 2008 a 2012, jà oriundos do novo padrÃo contÃbil. Ademais, buscou-se analisar os resultados a nÃvel individual (firma a firma), pelo conjunto das empresas amostradas e a nÃvel setorial. Ademais, controlaram-se, pela utilizaÃÃo de quatro variÃveis macroeconÃmicas, alteraÃÃes na situaÃÃo econÃmico-financeira das empresas efetivamente oriundas da atividade da economia. Utilizou-se mÃtodo de estimaÃÃo por sÃrie temporal que abrangeu o uso de modelo SARIMAX e do teste de previsÃo de quebra estrutural de Chow (1960). Teve-se como principal achado a identificaÃÃo de quebra estrutural da representaÃÃo do indicador de Endividamento das empresas brasileiras, afetado pela mudanÃa de tratamento do leasing conforme versa o CPC 06. Ademais, nÃo se localizou nos demais indicadores pesquisados quebra estrutural de comportamento devido ao novo padrÃo contÃbil. A anÃlise por setor mostrou que apenas se afetaram aqueles intensivos em operaÃÃes de leasing quanto ao Ãndice de endividamento / 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.
