with XBRL conversions handled for you.
The ARKK regulatory reporting portal converts your data into compliant XBRL for CRD IV filings, including COREP and Asset Encumbrance, incorporating the latest EBA guidelines and validations behind the scenes. Centralised workbooks link validation errors directly to the relevant cell, so issues are easy to trace and resolve.
Firms still relying on manual processes or spreadsheets face avoidable risk. Keeping pace with evolving capital and liquidity requirements is time-consuming, prone to error, and leaves teams exposed to non-compliance under FCA and EBA standards.

The ARKK portal aggregates your regulatory data, runs it through embedded validation logic, and produces recognised, submission-ready COREP returns with a full audit trail. Our team gives you clear visibility across every module and reporting cycle, so nothing gets missed ahead of a deadline.

+ What is CRD IV reporting?
CRD IV (Capital Requirements Directive IV) is an EU framework requiring credit institutions and investment firms to strengthen capital reserves, improve risk management, and increase transparency through reports such as COREP and Asset Encumbrance. It's designed to enhance the stability and resilience of the financial system across the EU banking sector.
+ How does ARKK support CRD IV compliance?
ARKK's regulatory reporting portal converts your data into compliant XBRL for CRD IV filings, incorporating the latest EBA guidelines and validations behind the scenes. Centralised workbooks link validation errors directly to the relevant cell, so issues are easy to trace and resolve before submission.
+ How long does it take to implement a CRD IV reporting solution?
Implementation time depends on the number of returns you're required to file and the complexity of your existing data setup. Most clients are operational well ahead of their next filing window, with our team providing hands-on support throughout onboarding.
+ Does ARKK integrate with existing data systems?
ARKK's regulatory reporting portal gathers your data through easy-to-use templates, runs it through embedded validation logic aligned to the CBI's schema, and produces a submission-ready XBRL return with a full audit trail. Our team keeps taxonomy and regulatory updates built into the portal, so your return stays aligned with current requirements.
+ How is data secured on the ARKK platform?
ARKK's portal is ISO 27001 certified, the internationally recognised standard for information security management, giving you a single, secure destination for uploading, tracking, and accessing your CRD IV submissions.
+ What are the risks of managing CRD IV reporting manually?
Manual CRD IV reporting increases the risk of validation errors, inconsistent data across submissions, and missed deadlines as capital and liquidity requirements evolve. Rekeying data into new templates each cycle also raises the chance of mistakes creeping into your filings.
