<p>This work is fundamentally dedicated to the analysis of the evolution of financial structure in mid-size companies, cut flowers producers and exporters, in Bogotá, D.C., the Colombian capital city, during the years 2003 to 2006. During this period the revaluation of the Colombian peso with respect to the American dollar was constant and powerful. The analysis is initially guided to notice the favourite financing sources of companies in that period, observing the right side composition of general balance and analyzing the most outstanding items tendency. The work continues with a study of the rate of exchange evolution during the period and its’ relationship with companies indebtedness. Finally, a multiple linear regression model is used where the independent variables are the most correlated indicators with the financial structure, to find the determinants and their influence in the financing decision, an analysis that contextualizes the initial observations.</p>
