De Nederlandsche Bank (DNB) Reporting Overview

AxiomSL provides all of the calculations, templates and reporting functionality needed for disclosures to De Nederlandsche Bank (DNB). Its platform includes embedded XBRL functionality and is perfectly designed to support banks migrating to the format.

AxiomSL’s ‘one platform’ model means the same system can be used for all other regulatory reporting requirements, greatly reducing the cost and complexity of compliance.

The AxiomSL platform leverages a firm’s existing data structure to quickly and accurately aggregate the required data from different lines of business. It reconciles the aggregated data back to its sources and uses it to run any necessary calculations before populating the templates that must be reported to the DNB.

Business dashboards give users the ability to drill down from the final reports to the source data, and to make manual adjustments if necessary. Once they are satisfied with their reports, users can sign off on them before they are submitted to the DNB via e-Line.

AxiomSL supports all electronic submission formats. Both XML and XBRL functionality is fully embedded in the reporting platform, which supports both formats from the same taxonomy. This ensures firms can smoothly migrate to XBRL when required to do so by the DNB, while retaining access to validations that are not contained within the standard. The flexibility of the platform also means users can do validations between XBRL and non-XBRL reports.

AxiomSL monitors changes to the requirements of the DNB and European authorities on an ongoing basis, and updates its calculations and templates accordingly. This relieves firms of onerous development work. Version controls allow users to track changes to regulations and to compare differences. The platform also gives users ongoing access to earlier iterations of calculations and templates, which they need when rerunning or resubmitting reports.

The same platform can be used for all other reporting requirements globally. This ‘one platform’ approach ensures consistency between reports submitted for different regulations. It also reduces cost and complexity because banks do not need to maintain separate systems to comply with different reporting requirements.

De Nederlandsche Bank (DNB) Reporting Challenges

Banks in the Netherlands must file a variety of complex reports to the DNB, based on both European and domestic requirements.

The DNB is responsible for collecting the reports required as part of the Capital Requirements Directive IV (CRD IV) in the Netherlands. In order to remain compliant, banks must aggregate and process large volumes of data, and ensure they have access to the latest versions of the European Banking Authority’s (EBA) calculations and templates.

Banks that do not consolidate their annual accounts using International Financial Reporting Standards (IFRS) are not subject to the EBA’s Financial Reporting (FINREP) requirements. However, these institutions (‘FINREP Title 9 banks’) must complete the DNB’s financial information survey, which is modelled on the EBA’s templates.

Banks also face a range of statistical reporting requirements in the Netherlands – including Balance Sheet Item (BSI) and Monetary Financial Institution (MFI) Interest Rate (MIR) filings. These DNB/ECB reports combine the data needs of both regulatory bodies.

Firms in the Netherlands must comply with a variety of other requirements including: Targeted Longer-term Refinancing Operations (TLRO), Financial Stability Board (FSB) Data Gap Initiative, Centraal Bureau Voor De Statistiek (CBS) savings, Deposit Guarantee Scheme (DGS), DRA RBG, DRA-SLB and DRA-CLM reports, as well as disclosures about interest-rate risk, loan-level data and monetary distressed loans.

At present the majority of DNB reports are submitted in XML, via its e-Line online portal. However, the DNB has indicated that it will migrate to XBRL. This will be a significant change for banks, which will need to implement three-dimensional taxonomies with embedded validation rules, and which will require a flexible platform in order to manage the transition smoothly (for more on this topic, see this blog post).
