Harmonisation of reporting content and templates

Article 20 addresses the practical challenge of ensuring that incident reports submitted across the EU are comparable, complete, and useful for supervisory purposes. Without standardized templates and data fields, the value of harmonized reporting requirements would be significantly diminished by inconsistency in how information is captured and communicated.

The ESAs are mandated to develop implementing technical standards (ITS) that specify exactly what information must be included in each type of report — initial notification, intermediate report, and final report. These ITS define the data fields, formats, and structures that financial entities must use, ensuring machine-readable, comparable data across the entire EU financial sector.

Standardized timelines for each reporting phase are also specified through these ITS. This ensures that supervisors can expect reports at predictable intervals and can coordinate their supervisory responses accordingly. The timelines balance the need for prompt information with the practical reality that comprehensive analysis takes time.

The harmonization effort extends beyond just forms and timelines. The ITS must also consider the burden on financial entities, particularly smaller ones, and ensure that reporting requirements do not divert excessive resources from the actual incident response. The goal is efficient, focused reporting that provides supervisory value without becoming an end in itself.
