Previously published in October 2014, the matrix captures the latest Counterparty ID waterfalls for various jurisdictions to reference as industry standard. Counterparty IDs are used to identify the counterparties, including reporting counterparties, to a transaction. Most reporting regulations specify allowable values for party identification, however, where such values are not available, the reporting party may need to use an alternative party identifier. Reporting jurisdictions may have different preferred waterfalls for alternative Counterparty IDs. The waterfall has been updated to reflect the possibility that (1) in the near future, mapping of alternate counterparty IDs to LEIs will no longer be acceptable for EMIR and (2) the HKMA allows the Certificate of Incorporation or Certificate of Registration and the Business Registration Number to be used as identifiers.
