During the last decades, derivative transactions disclosure has raised interest of financial information users, who more and more demand for detailed information about these operations. Therefore, the purpose of this investigation study is to measure and identify the type of information related to derivative transactions that is disclosed by Portuguese companies. The financial statements of all quoted companies during the economic exercises of 2001 and 2004 have been anlysed, concluding that only about 50% of the companies disclose information on these transactions. We identified 397 and 669 references to derivative instruments for the exercises 2001 and 2004 respectively, and concluded that this increase, which might be explained by the companies concern about IAS 39 future adoption, is due to non financial companies’ disclosures.
