Identity Crisis

In 2007, the Committee of European Securities Regulators (CESR) started to discuss the introduction of the Alternative Instrument Identifier (AII), to help firms identify derivatives and meet the transaction reporting requirements of the Markets in Financial Instruments Directive (MiFID) (Inside Reference Data, October 2007).

Currently, firms cannot report derivatives transactions admitted to trading on regulated markets where the ISO 6166 ISIN codes are not the industry method of identification.
