Between 2004 and 2008, 199 public stock offers were registered in Brazil, of which 111 were initial stock offers, at the São Paulo Stock Exchange, Brazil’s main stock exchange; and 88 public stock offer registered at Comissão de Valores Mobiliários (Brazilian SEC), with several reasons. Using a sample of 50 public offers, we observed the best practices adopted by the main financial appraisers in Brazil. We concluded that these appraisers tend to use the better known models and assumptions accepted in the academic world, according with what is practiced in other countries, adjusted to Brazilian reality. We observed some quantitative differences between the assumptions in the pricing of initial stock offers and public stock offers, where the second one showed more conservative assumptions than the first.
