Collection of additional reference data to determine the European reporting obligations Scope Credit institutions governed by Belgian law. Financial services groups headed by a Belgian regulated institution (hereinafter "financial holding companies governed by Belgian law") Financial services groups headed by an institution governed by foreign law (hereinafter "financial holding companies governed by foreign law") Financial services groups headed by a Belgian mixed financial holding company (hereinafter “mixed holding companies'”. Branches established in Belgium of credit institutions governed by the law of another EEA Member State Branches established in Belgium of credit institutions governed by the law of a third country Summary/Objectives As part of their prudential supervisory tasks, the supervisory authorities (the Bank, the ECB and the EBA) periodically collect prudential data from the above-mentioned institutions. To determine these reporting obligations, metadata (the so-called Master Data attributes) are used. Within this framework, the EBA and the ECB need new additional Master Data attributes. In its role as national competent authority within the Single Supervisory Mechanism (SSM), the Bank requests these additional data from the above-mentioned institutions through this Communication. The above-mentioned institutions which are subject to the Bank's supervision and which are also at the highest level of consolidation within the Member States participating in the SSM, are requested to also report these additional attributes to the Bank for those entities within their group that are located in a Member State not participating in the SSM, or in a third country.

Communication – Page 2/3 NBB_2020_001 – 16 January 2020 Dear Sir, Dear Madam, As part of their prudential supervisory tasks, the supervisory authorities (the Bank, the ECB and the EBA) periodically collect prudential data from the above-mentioned institutions (hereinafter “institution” or “institutions”) subject to their supervision. In order to allow the supervisory authorities to determine the European prudential reporting obligations for the institutions under their supervision, metadata (the so-called Master Data attributes) are used. At the request of the ECB, the Bank needs to manage some new additional Master Data attributes. The main purpose of the additional Master Data attributes requested is to better map and understand the group structures of the institutions, both inside and outside the SSM & the European Economic Area. This request arises from the obligations below.

1. ECB Guideline for the attention of the national authorities
   The Master Data attributes of each institution are managed by the ECB in the RIAD Database1. The ECB Guideline for the attention of the national authorities has a dual purpose. On the one hand, it lays down certain arrangements between the different authorities and the ECB regarding the management of the information in RIAD. On the other hand, through this guideline the ECB requests additional Master Data attributes via the national authorities.
2. EBA EUCLID project2
   In 2016, the EBA Board of Supervisors (BoS) decided to significantly expand the EBA data infrastructure in the future through the EUCLID project. Whereas the EBA currently receives only the consolidated prudential reports from the largest institutions per EU Member State, under the EUCLID project the EBA will receive all prudential reports, both statutory and consolidated, from all institutions within the EU. The EBA will receive these data through the national authorities, based on the so-called "sequential approach" for data transmission. This approach means that the institutions only have to report their data once, namely to their national authority (i.e. the Bank for the Belgian institutions). The national authorities within the SSM will then share these data with the ECB. The ECB will in turn transmit the data to the EBA. This approach is expected to be applied for both the Master Data attributes and the actual prudential reports. Thus, as the EBA will receive more reports from a larger group of institutions in the near future, there is an additional need for Master Data attributes to determine the reporting obligations. In order to allow the ECB to play its role in this sequential approach, it has reviewed these additional attributes requested by the EBA. The ECB found that for some of these attributes it needs to rely on the availability of these data within the national authorities. In its role as national authority within the SSM, the Bank is responsible for transmitting the data resulting from these obligations to the ECB in a timely manner. As the Bank does not currently have all these data at its disposal, it requests these additional data from the above-mentioned institutions through this Communication. The list of attributes requested by the ECB is annexed to this Communication. 1 Register of Institutions and Affiliates Data (RIAD database) - The RIAD database is managed by the ECB and the national central banks and authorities, and contains a wealth of information on the different financial entities within the European System of Central Banks (ESCB), the euro area and the SSM. The database thus also supports the different tasks within the euro area, the ESCB and the SSM. More specifically, among other things, the prudential reporting obligations of each institution are determined via the Master Data attributes available in RIAD. 2 European centralised infrastructure for supervisory data (EUCLID). The EBA will have access to the larger amount of data as from the reports as per 31 December 2020.

NBB_2020_001 – 16 January 2020 Communication – Page 3/3 Given the dynamic nature of the reporting obligations, further adjustments to the Master Data attributes will remain possible in the future. Reporting modalities and timeframe Institutions are requested to report the new Master Data attributes, as set out in the Annex to this Communication, to the Bank by 31 March 2020 at the latest. The attributes should be reported through the Bank's OneGate application (Domain MBS). After this one-time periodic reporting, the institutions are requested to communicate any changes in these data to the Bank as soon as possible. They should do so by adapting the data, where necessary, in the OneGate application. The institutions subject to the Bank's supervision, which are also at the highest level of consolidation within the Member States participating in the SSM, are requested to also report these additional attributes to the Bank for those entities within their group that are located in a Member State not participating in the SSM, or in a third country. Yours faithfully, Pierre Wunsch Governor
