1. NCBs have the right to provide credit data, including data collected by another NCB, to reporting agents by establishing or enhancing feedback loops or other information services from CCRs to reporting agents. They may provide a subset of the credit data collected under this Regulation, in line with best practices and to the extent allowed by the applicable legal confidentiality regime. Reporting agents may use the data exclusively for managing credit risk and improving the quality of credit information available to them with regard to existing or prospective instruments. They shall not share the data with other parties, unless data sharing with service providers is strictly necessary for these purposes, and the data are used only in relation to the reporting agent and the reporting agent ensures appropriate confidentiality protection under a contractual agreement that excludes any other use of the data, and provides for the anonymisation of the data wherever possible and deletion of the data as soon as the purpose for which they have been shared has been achieved. Any further data transmission by the service provider, and any data sharing with commercial providers of credit data is forbidden.
