In a project evaluation, as a factory construction or a telecommunications network expansion, the traditional discounted-cash-flow analysis is largely used, despite it is well known restrictions, that tend to reach less consistent results. These restrictions could be acceptable when the intention is just to guarantee the project s viability. In a public company privatization process, however, it is critical to reach an accurate value to the firm, not just to maximize the sale s value, but also, due to the controversial nature and some society s segments resistance of the public companies sales, to avoid political wastage caused by process legitimacy suspects. In accordance to the Brazillian national privatization program (Programa Nacional de Desestatização) orientation, the discounted-cash-flow methodology has been largely used in the public companies evaluation. The EMBRATEL sale was not different, and was observed a large agio in this process. This paper was written with the intention of formulating some hypothesis about the managerial flexibility caused by the EMBRATEL sale, that could be captured by the real options evaluation methodology. Presumed that the objective is to maximize the sale s value of the public companies, the valuators have the real options methodology as an alternative for the next public companies to be privatized.
