Previous issue date: 2016-03-29 / This research has provided a discussion about the impacts on qualitative characteristics of comparability of information resulting from the lack of monetary correction of financial statements in the current Brazilian economic scenario. In face of that, the monetary correction of balance sheet was applied in the financial statements of Brazilian companies included in the subsector of steel and metallurgy that are listed on BM&FBOVESPA, from 2009 to 2014. It was calculated the comparability ratio between different companies and between different periods of the same company both at historical values and at adjusted for inflation values, considering the net profit, return on equity (ROE) and the economic value added (EVA??), which are important performance ratio used by investors as users of accounting information. Hypotheses were made for each variable in order to verify the differences of comparability between the adjusted information and the historical information. Those hypotheses were tested through the application of Student???s T-test, assuming as the null hypothesis the equality between the comparability of adjusted ratio and historical ratio, so the test???s role is indicate its acceptance or rejection. Moreover, it was calculated and analysed the percentage change between the comparability ratio considering inflationary effects and the comparability ratio without those effects. The results of hypothesis tests have shown comparability between different companies for all variables. In another hand, the results of the time axis tests have shown comparable differences for the ROE, with no statistical evidence of differences in comparability between periods for net income and for EVA??. However, the percentage change of the adjusted ratio of temporal comparability compared to historical ratio for those variables has shown significant impacts on the companies, which should not be neglected. This discovery corroborates the importance of the monetary correction of financial statements. / Este estudo promoveu uma discuss??o sobre os impactos causados ?? caracter??stica qualitativa de comparabilidade da informa????o decorrentes da aus??ncia da corre????o monet??ria das demonstra????es cont??beis no atual contexto econ??mico brasileiro. Para tanto, aplicou-se ??s demonstra????es financeiras das empresas brasileiras do subsetor de ???siderurgia e metalurgia??? listadas na BM&FBOVESPA, no per??odo de 2009 a 2014, a sistem??tica de corre????o monet??ria de balan??os (CMB). Foram calculados ??ndices de comparabilidade entre diferentes empresas e entre per??odos da mesma empresa tanto a valores hist??ricos quanto a valores monetariamente corrigidos, considerando-se as vari??veis lucro l??quido, retorno sobre o patrim??nio l??quido (ROE) e valor econ??mico agregado (EVA??), importantes indicadores de performance utilizados pelos investidores enquanto usu??rios da informa????o. Formularam-se hip??teses para cada uma destas vari??veis buscando-se verificar a exist??ncia de diferen??as de comparabilidade entre as informa????es corrigidas e as informa????es hist??ricas. Estas hip??teses foram testadas por meio da aplica????o do teste t de Student, pressupondo-se como hip??tese nula a igualdade entre os ??ndices de comparabilidade corrigidos e os ??ndices hist??ricos, cabendo ao teste indicar sua aceita????o ou rejei????o. Ademais, foram calculadas e analisadas as varia????es percentuais entre os ??ndices de comparabilidade com os efeitos inflacion??rios e os ??ndices isentos destes efeitos. Os resultados dos testes de hip??teses evidenciaram diferen??as de comparabilidade entre empresas para todas as vari??veis. J?? os resultados dos testes relativos ao eixo temporal apontaram diferen??as de comparabilidade para a vari??vel ROE, n??o havendo evid??ncia estat??stica de diferen??as na comparabilidade entre per??odos para o lucro l??quido e EVA??. No entanto, as varia????es percentuais dos ??ndices corrigidos de comparabilidade temporal em rela????o aos ??ndices hist??ricos para estas vari??veis revelaram impactos relevantes para parte das empresas, os quais n??o devem ser desprezados. Os achados da pesquisa corroboram com a import??ncia da corre????o monet??ria das demonstra????es financeiras.
