The traditional discounted cash flow method, which is commonly used by companies to analyze capital budgeting investments, has important limitations when uncertainty and managerial flexibility are present. For these types of project, option pricing methods are more appropriate, since they allow the value of these managerial flexibilities to be adequately captured and valued. In this work we analyze the investment in a project through a venture capital fund, and show that the use of the real option method for the valutation of this type of projects and financing scheme is recommended, given these projects are in the initial stages of development, have a high degree of uncertainty and allow significant managerial flexibility. The Venture Capital industry is typically represented by firms with high growth rates in their initial years and high volatility of the expected returns. The results show that the project has a negative NPV under the traditional discounted cash flow method, but with real option valuation the project value was significantly higher, which shows that non optimal decisions may occur if project flexibility is not valued. We conclude that when high levels of uncertainty and flexibility exist, such as is the case of investments in Venture Capital projects, the real options method provides a more adequate value for the project.
