The Argentina Securities Commission (CNV) issued General Resolution No. 1054, amending existing rules to update procedures governing the authorisation, suspension, delisting and trading of individually issued negotiable securities and to expand investor access to key financial information. The changes apply to individually issued instruments eligible for trading on markets, including deferred payment cheques and exchange promissory notes. Markets where these instruments are listed and or traded must implement a permanent disclosure mechanism accessible to both member agents and the investing public, covering details of outstanding instruments such as identifiers, issue and maturity dates, amounts, admission to trading dates and other relevant circumstances, as well as identification data for each drawer, including its tax identification code.
