160. Technical Guidance on Harmonisation of critical OTC derivatives data elements (other than UTI and UPI) (also referred to as "CDE guidance") is one of the reports delivered by the CPMI-IOSCO Harmonisation Group. It follows a request from FSB to develop global guidance on the harmonisation of data elements reported to TRs and important for the aggregation of data by authorities. The report comprises technical guidance on 101 data elements, including their definitions, formats, allowable values and existing industry standards.

161. The CDE guidance is addressed to authorities, rather than directly to market participants. This means that it is in the remit of the respective authorities to issue specific reporting requirements to market participants. In particular, it is for the authorities to decide which of the data elements covered by the guidance should be reported in their jurisdictions.

162. As clarified in the Consultation Paper, ESMA intends to follow the specifications of data elements included in the global guidance, however for some of the data elements minor adjustments are needed. Such adjustments should not prevent the aggregation of EMIR data with data reported in other jurisdictions that follow the CDE guidance.
