COREP and FINREP: which returns apply to you.

What each acronym covers

COREP and FINREP are the practitioner names for the two reporting streams built on Regulation (EU) No 575/2013 and its implementing technical standards. COREP carries the prudential position: own funds, own funds requirements, the resulting ratios, and the detailed blocks for credit, market and operational risk, leverage, large exposures and liquidity. FINREP carries the financial position: the balance sheet, the income statement and the breakdowns a supervisor uses to read them.

They are not alternatives. An institution can owe both, one, or a subset of either, and the subset is rarely intuitive.

The five axes that decide scope

Work through these in order. Each one narrows the set before the next is applied.

1. Entity type. Credit institutions report under the institution framework. Investment firms report under the separate investment firm regime and its own implementing standards, with defined cross-references back to the institution templates for firms that use provisions of the capital requirements framework. Assuming an investment firm files COREP as a bank does is a common and expensive error.
2. Reporting level. Individual, sub-consolidated and consolidated reporting are separate obligations with separate populations. A waiver at one level does not remove the obligation at another.
3. Accounting framework. FINREP scope turns on the framework applied at the reporting level. The consolidated financial reporting obligation in the capital requirements regulation attaches to institutions applying international accounting standards at that level, and has been extended to national accounting frameworks and, in some jurisdictions, to individual level by the competent authority.
4. Size and complexity classification. The distinctions between large institutions, other institutions and small and non-complex institutions determine which templates apply, at what depth and how often. The classification is a legal test, not a self-description.
5. Activity thresholds. Specific blocks switch on when a measure crosses a threshold — trading book size, derivative activity, foreign exchange or commodity positions, securitisation, or encumbered assets. Entry and exit criteria are defined, so a block does not switch off the moment activity dips.

The COREP blocks

The prudential stream is best understood as one core plus several conditional extensions.

The FINREP blocks

FINREP starts from the primary statements and then adds supervisory breakdowns that do not exist in published accounts.

• Balance sheet and income statement — assets, liabilities, equity and profit or loss on the supervisory classification.
• Financial instrument detail — by product, counterparty sector, country and residual maturity.
• Credit quality — performing and non-performing exposures, forbearance, impairment and collateral.
• Off-balance-sheet and derivative detail — commitments, guarantees and derivative holdings.
• Group and structural information — scope of consolidation, related parties and geographical breakdowns.

The depth of these breakdowns is where FINREP scope decisions bite. A small and non-complex institution and a large institution can both owe a balance sheet, and owe it in very different detail.

Frequency, thresholds and remittance

Frequencies run from quarterly to annual by template, with some blocks reported less often for smaller institutions. Reporting reference dates and remittance dates are fixed by the implementing standards, with an adjustment where a remittance day falls on a non-business day in the jurisdiction concerned. Threshold-driven blocks have explicit entry and exit criteria so the population does not oscillate.

Three operational consequences are worth planning for. Reference dates align to the financial year end, so a non-calendar year end changes the calendar rather than the obligation. Amended returns are resubmissions of the full report package, not deltas. And a single reference date typically produces several packages — individual and consolidated — from one dataset.

Taxonomy versions and amendments

The implementing standards are amended regularly, and the reporting framework is versioned with them. The standards on supervisory reporting of institutions have been recast, and the investment firm standards amended in consequence, so the correct starting point is always the instrument currently in force rather than the one a previous cycle was built against.

Practically, that means two things: the taxonomy version is part of the filing, not a background detail, and a mapping built for one framework release is validated again against the next. New templates — for instance for output floor effects and for exposures to crypto-assets — arrive with framework releases rather than separately.
