548. ESMA also proposed in the Consultation Paper that there should be a confirmation of the number of commonly paired and reconciled records between each pair of TRs for the purposes of establishing the data integrity of the reconciliation process. Following the feedback received, ESMA has considered whether to include in the draft technical standards also a reference to the total number of derivatives exchanged between each pair of TRs. Given that the key aspect is to ensure that the number of paired and reconciled derivatives is correct, ESMA does not propose to add more information.

549. ESMA understands that the corresponding relevant information can be included as additional data in the relevant XML files.

550. One respondent proposed that TR should exchange aggregate values for numerical attributes. ESMA disagrees because it would be too burdensome to confirm between the TRs some aggregate metrics and the checks should be better performed at the level of the reporting entities.

551. Several respondents asked for a clarification on how to include the number of paired and reconciled derivatives between a pair of TRs in the report. ESMA confirms that the information on the total number between TRs is separate from the results of the reconciliation process which are at derivative level. Moreover, this information is necessary to ensure that TRs do not provide different information to counterparties. However, ESMA confirms that TRs could at least exchange the number of trades that are reconciled at aggregated level.
