This study aimed to identify what are the key attributes that characterize the Boards of Directors (BoD) in Brazil, thus allowing for a better understanding of their influences on the capital market. I have been found that there is a high degree of correlation between the 31 analyzed characteristics, suggesting that other researches on the topic could have evidenced the relationships of some variables that probably were reflecting many other strongly correlated characteristics. The main target was to better understand the environment in which the Boards of Directors are situated in order to define, in fact, what are the key attributes of these Boards based on the variance of a larger set of characteristics. The factor analysis (FA) allowed a deeper analysis of these characteristics, getting rid of the specific correlations between them and then building non-correlated factors. From this scenario, five indexes were built to reflect the factors extracted from the FA, allowing them to be related to the value and performance of firms through multiple regressions; these factors are: variable and fixed remuneration, dedication of the members to the Board, basic training and degree of the BoD members (Master and PhD degree). The results were divided into three sections: i) characterization of the Boards of Directors in Brazil, to allow a better understanding of the BoD´s environment in the country; ii) determination of the key characteristics of these Boards, in other words, which are the characteristics that explain most of data variance, through factor analysis and; iii) the relationship between the constructed indexes and the return, abnormal return, Tobin´s Q, ROA e ROE, in order to verify if the features that summarize the environment of the BoD are perceived as important by investors at the time of the investment. In addition, I also found that the remuneration of the Directors is responsible for explaining about 40% of the data variance referring to the Boards of Directors, thus suggesting that this characteristic is of great importance in the spectrum of corporate governance, especially regarding the Boards of Directors of the firms. I also identified that the "fixed compensation" factor influences negatively and significantly both in abnormal return and Tobin´s Q. The relationship between dependent variables and other factors has also been tested and the results suggest that the dedication of the Board members is significant to explain Tobin´s Q and that the level of education of the members explains significantly the return, abnormal return and the Tobin´s Q.
