An expert evaluation report is a document drawn up by one or more specialists, who is/are generally independent to the process, with the aim of defining the attributable amount of equity (the assets, rights and obligations as a whole), according to Generally Accepted Accounting Principles and using either evaluation methodology or the market value. Although in many cases they are not obligatory, the expert reports are often used to recommend decisions or to justify decisions at the administrative board or general assemblies. Expert valuation reports are often used in merger, acquisitions, corporate restructurings and other important corporate transactions.
