For this was a descriptive study with a quantitative approach, using the technical procedures of bibliographic and documentary research.

The analysis appealed both to the interaction of all data between the years 2010 and 2011 as the interaction between the same quarters. To verify the occurrence of significant differences, were used analysis of variance in randomized blocks and as the quarters corresponding to a source of variation in time, were chosen to analyze the data in the plot scheme subdivides the time. There was, first, the normal distribution of data as the presumption model. Thus, were applied the analysis of variance and, finally, to compare the means, in order to check whether there are significant differences between EBITDA and the FCO, were used the test of Scott-Knott. The results found that the companies analyzed, with regard to the analysis of all data between the years 2010 and 2011 and the first and second quarters of the quarters in the analysis, there were significant differences between the two indicators.
