National and international exigencies on increasing the quality of accounting information generated by evaluation by comparison

The approach by comparison establishes the limits of the shares market value by analyzing the prices, normally paid for shares to the competing entities to the one evaluated. In order to select the comparison base, the motivations of the parties involved in the transaction must be identified. Selling prices which reflect a different motivation than the typical motivation of the participants on the market shall be eliminated. These prices will be analyzed by using some proper comparison units, being adjusted depending on the differences between the compared entities and the evaluated entity. The application of these approaches requires some sufficient market information, as well as a degree of market stability, in order to ensure the relevance of the comparison bases used.
