Considering the existence of asymmetric information between managers and investors, Myers (1984) affirms that the configuration of corporate capital structure is based on a hierarchy known as Pecking Order Theory (POT), favoring sequentially the use of internal resources, debt emission and, at last, stocks issues. The POT's empiric verification breaks up into methodological matters; some times being confirmed and other does not. In this article a different methodology is proposed recognizing the characteristics of companies such as size, profitability and growth, to explain the financing of the deficit. The results indicate that only the smaller size companies in the sample, negative profitability, and lower growth present a weak adherence to the POT's forecasts. For this reason this cannot be considered a general theory to explain the corporate capital structure.
