COREP (Common Reporting) is the standardized reporting framework for prudential information under the Capital Requirements Regulation (CRR). This guide covers the full scope of COREP requirements, helping banks and investment firms understand their reporting obligations.
Key Takeaways
- COREP covers capital adequacy, large exposures, and liquidity reporting
- Reporting frequency varies by template: quarterly, semi-annual, or annual
- DPM 2.0 introduces significant structural changes
- File naming conventions are strictly enforced by NCAs
- Pre-validation is essential to avoid rejection
COREP Framework Overview
COREP provides a unified framework for prudential reporting across the EU:
• Capital requirements (own funds, risk-weighted assets)
• Large exposures monitoring
• Leverage ratio reporting
• Liquidity coverage and net stable funding
• Asset encumbrance
Reporting is mandatory for credit institutions and investment firms under CRR supervision.
Key Templates
Core COREP templates include:
• C 01.00 - Own Funds
• C 02.00 - Own Funds Requirements
• C 03.00 - Capital Ratios
• C 04.00 - Memorandum Items
• C 05.01/02 - Transitional Provisions
• C 06.02 - Group Solvency
• C 07.00 - Credit Risk Standardised
• C 08.01/02 - Credit Risk IRB
Additional templates cover market risk, operational risk, and securitisation.
Reporting Frequencies
Template frequencies vary:
• Quarterly: Core capital templates, credit risk, large exposures
• Semi-annual: Detailed IRB templates, leverage ratio
• Annual: Low-frequency disclosures, historical data
Remittance dates are typically: Q1 (May 12), Q2 (Aug 11), Q3 (Nov 11), Q4 (Feb 11). Check your NCA for specific deadlines.
DPM Structure
The Data Point Model (DPM) defines all COREP data points. Each cell in a template maps to dimensions (row, column, sheet, z-axis). Understanding DPM helps troubleshoot validation errors. DPM 2.0 restructures dimensions significantly—review the mapping documentation carefully.
Submission Requirements
To submit COREP reports:
1. Generate XBRL or xBRL-CSV files per EBA specification
2. Apply correct file naming convention
3. Validate against current taxonomy and business rules
4. Submit via your NCA's designated portal
5. Monitor for rejection notifications
Use Xerify's naming checker tool to verify file names before submission.
