Observing the deficiencies of traditional methods in meeting the demands of today&rsquo / s infrastructure development has been motivating countries towards privatization of these sectors. However, due to the differences in these sectors as compared to other businesses, privatization can not be performed without strict regulations. Today, concession agreements like BOT models seem the best way for solving the problems. Financing of concession agreements plays a key role. In Turkey, most BOT projects are financed by capital structure that has a maximum debt ratio, which is allowed by the law. The objective of this study is to examine whether the maximum amount of debt ratio is the optimum amount of debt ratio. Optimization is carried out by analyzing the trade off between benefits of tax shield and the loss due to financial failure as a result of change in leverage, assuming other things are the same. A theoretical framework is developed for the analysis by selecting Adjusted Present Value Method as a financial tool. Energy generation sector in Turkey is analyzed, stock market data in Turkey is used for the analysis, and a bankruptcy prediction model is proposed for BOT projects in Turkey. Finally, by using the theoretical framework, an actual BOT model hydro electric power plant proposal is analyzed for optimization of capital structure.

A teoria de trade off defende que administradores busquem um nível estático e pré-determinado de endividamento para maximizar o valor da empresa. Portanto, é esperado que saltos na alavancagem não sejam frequentes e eventuais desvios em relação ao nível ótimo sejam rapidamente corrigidos. Este trabalho analisou a estrutura de capital das empresas listadas na B3, de 2010 a 2016, a fim de verificar se a teoria de trade off pode explicar o comportamento observado durante esse período. Foi constatado que, embora não retornem prontamente ao nível anterior de alavancagem, as empresas permaneceram em níveis compatíveis com o ótimo, o que é consistente com a teoria de trade off e sinaliza que flexibilidade financeira é também uma preocupação. / Firms normally leverage their capital structure through debt issuance, in order to manage their financial and operational needs. Trade off theory suggests that managers must aim at a pre-determined and static leverage target to maximize the firm’s value. Therefore, one should not expect to observe frequent jumps in leverage, and any difference between optimal and observed leverage would be promptly corrected. This paper studied the capital structure of companies listed at B3, from 2010 to 2016, aiming to investigate if trade off theory can be used to explain their behavior during this period. It was observed that, although companies do not return to previous leverage levels quickly, they tend to stay around optimal levels, which is consistent with trade off theory and suggests that financial flexibility is also a concern.

The diploma thesis is focused on the issue of the capital structure of a selected company and the possibilities of affecting it from company’s perspective. The basic concepts related to the capital structure, the issue of optimizing the capital structure, the factors that affect the capital structure and the financial performance of the company are explained. Furthermore, the work deals with a proposal of ways or sources, by which the company could optimize its capital structure in order to streamline its business.
