determination of model 3 (corresponding to consolidated financial statements) and the<br />

coefficient of determination of model 1 (corresponding to individual financial<br />

statements). In this respect, to better delineate the trend, we split the analyzed period<br />

(2003-2008) in three sub-periods of two years, computing for each sub-period the<br />

average explanatory power for the corresponding years (see figure 2). From the<br />

conducted analysis results an increase in time of the difference between the two<br />

coefficients of determination, from 8,8% (for 2003-2004) to 25,8% (for 2007-2008).<br />

Considering the statistical significance of the respective difference certified by<br />

statistic tests applied to verify hypothesis 1 (at 0,001 level), we can conclude that the<br />

third hypothesis, as well, regarding the increasing trend of the relevance surplus<br />

provided by consolidated information is statistically confirmed.<br />
