(a) If an internationally recognized standards-setting system that imposes fees and usage restrictions on persons that obtain UICs for their own usage that are fair and reasonable and not unreasonably discriminatory and that meets the criteria of paragraph (b) of this section is recognized by the Commission and has assigned a UIC to a person, unit of a person, or product (or has endorsed a methodology for assigning transaction IDs), the registered security-based swap data repository shall employ that UIC (or methodology for assigning transaction IDs). If no such system has been recognized by the Commission, or a recognized system has not assigned a UIC to a particular person, unit of a person, or product (or has not endorsed a methodology for assigning transaction IDs), the registered security-based swap data repository shall assign a UIC to that person, unit of person, or product using its own methodology (or endorse a methodology for assigning transaction IDs). If the Commission has recognized such a system that assigns UICs to persons, each participant of a registered security-based swap data repository shall obtain a UIC from or through that system for identifying itself, and each participant that acts as a guarantor of a direct counterparty's performance of any obligation under a security-based swap that is subject to §242.908(a) shall, if the direct counterparty has not already done so, obtain a UIC for identifying the direct counterparty from or through that system, if that system permits third-party registration without a requirement to obtain prior permission of the direct counterparty.

(b) A registered security-based swap data repository may permit information to be reported pursuant to §242.901, and may publicly disseminate that information pursuant to §242.902, using codes in place of certain data elements, provided that the information necessary to interpret such codes is widely available to users of the information on a non-fee basis.
