On 31 May 2024, the three European Supervisory Authorities (ESAs), namely the European Securities and Markets Authority (ESMA), the European Banking Authority (EBA) and the European Insurance and Occupational Pensions Authority (EIOPA), published templates and tools for a voluntary dry run exercise to support the implementation of DORA. All materials can be found on the webpage of the dry run exercise and Financial Entities (FEs) can use them to prepare and report their registers of information of contractual arrangements on the use of information and communications technology (ICT) third-party service providers (TPSPs) in the context of the dry run exercise, and to understand supervisory expectations for the reporting of said registers from 2025. The published materials include: templates for the registers of information with an example (in Excel format), a draft technical package for reporting, including a data point model (DPM), an annotated table layout and validation rules; an optional tool (VBA macro) to assist with the conversion of Excel templates into .csv files and .zip files; a frequently asked questions (FAQ) document regarding the exercise; a draft taxonomy. The participating FEs are expected to submit their registers of information to the ESAs via their CAs between 1 July and 30 August 2024. A dedicated virtual workshop will be organised on 10 June 2024 from 10h to 12h, and FEs are invited to register by 5 June 2024 via the following link.
