Defensible Solvency II & Solvency UK reporting

Bring capital calculations, regulatory validation, and QRT reporting together on a transparent, audit-ready foundation.

How CWAN supports the Solvency II and Solvency UK reporting chain.

Data
Collection

Unify and prepare regulatory-ready investment data

  • Ingest custodian, accounting, and market data
  • Standardize asset classifications for Solvency II
  • Support look-through for funds and complex assets
  • Reconcile positions and valuations

Calculation

Apply prescribed capital methodology consistently

  • Calculate SCR for investment risk (Standard Formula)
  • Apply regulatory stress factors
  • Aggregate risk using correlation matrices
  • Generate investment-level capital outputs

Validation

Detect errors
before submission

  • Apply built-in regulatory validation checks
  • Flag missing or inconsistent data
  • Surface capital anomalies
  • Track and log exceptions

Reporting

Produce regulator-ready compliance reports

  • Auto-populate investment-related QRTs
  • Maintain version control by reporting period
  • Track adjustments and overrides
  • Export submission-ready templates

How CWAN supports all three pillars of Solvency II and Solvency UK.

Pillar 1 — Quantitative Requirements (Capital Adequacy)

Pillar 1 defines capital requirements under the Solvency II framework, including the Solvency Capital Requirement (SCR) and Minimum Capital Requirement (MCR).
CWAN supports Pillar 1 by:

  • Calculating SCR for investment-related market risk modules under the Standard Formula: interest rate risk, equity risk, spread risk, currency risk, property risk, concentration risk, counterparty default risk, and more
  • Applying prescribed regulatory stress factors
  • Aggregating capital charges using correlation matrices
  • Producing transparent, traceable investment-level capital outputs

By standardizing calculation logic and reducing spreadsheet dependency, CWAN strengthens capital consistency and reduces operational modeling risk.

Pillar 2 — Governance and Risk Management

Pillar 2 focuses on governance, internal controls, and the Own Risk and Solvency Assessment (ORSA).

CWAN supports Pillar 2 by strengthening the underlying control environment through:

  • Centralized, reconciled investment data
  • Logged adjustments and override governance
  • Role-based access controls
  • Workflow tracking and validation logging
  • Audit trails across calculation and reporting stages

While CWAN does not replace governance frameworks or ORSA narrative processes, it provides the data integrity, transparency, and control evidence that support supervisory review and internal oversight.

large
Pillar 3 — Supervisory Reporting and Disclosure

Pillar 3 governs regulatory reporting through Quantitative Reporting Templates (QRTs) and disclosures. CWAN supports Pillar 3 by:

  • Automating investment-related QRT population from reconciled data
  • Supporting templates such as:
    • S.06.02 – List of Assets
    • S.06.03 – Fund Look-Through
    • S.08.01 – Open Derivatives
  • Applying built-in validation checks
  • Maintaining reporting-period version control
  • Preserving traceability from QRT outputs to underlying exposures
  • Exporting regulator-ready reporting outputs

This reduces manual intervention while improving reporting accuracy and audit defensibility.

Solvency II FAQs

What are Solvency II requirements for insurers?

Solvency II requires insurers to calculate the Solvency Capital Requirement (SCR) using prescribed stress factors, maintain sufficient own funds to cover SCR and MCR thresholds, implement robust governance and risk management controls, and produce regulator-ready QRT outputs, including XBRL when required.

CWAN supports investment-related Standard Formula SCR calculations and populates investment-related QRTs from reconciled data, with embedded validation controls and audit traceability to support supervisory review.

Who needs to comply with Solvency II?

Solvency II applies to insurance and reinsurance undertakings authorized within the European Economic Area (EEA). It also applies at the group level to insurance groups headquartered in the EU and, in certain cases, to third-country groups with EU-regulated entities. Solvency UK applies to insurers regulated by the UK Prudential Regulation Authority (PRA).

CWAN supports insurers operating under Solvency II and Solvency UK by centralizing investment data, applying Standard Formula investment risk calculations, and populating investment-related QRTs within a controlled, traceable workflow designed for supervisory scrutiny.

What are the risks of failing to comply with Solvency II?

Non-compliance essentially means an insurer is not properly managing the relationship between its assets and liabilities, and poses severe financial, operational, and regulatory risks. Failure to comply with Solvency II requirements can result in:

  • Supervisory intervention
  • Capital add-ons imposed by regulators
  • Increased reporting and remediation requirements
  • Restrictions on dividend distributions
  • Heightened ongoing scrutiny
  • In severe cases, risk to authorization

By structuring capital calculation and reporting within a governed system, CWAN helps insurers move from reactive remediation to defensible, repeatable compliance.

What is the difference between Solvency II and Solvency UK?

Solvency II: Solvency II is a European Union regulatory framework that applies to insurance and reinsurance companies operating within the EU. It sets out prudential requirements, risk management standards, and reporting and disclosure obligations for the entire EU insurance industry. It aims to create a harmonized and consistent regulatory environment across the EU member states.

Solvency UK: Solvency UK, often referred to as the UK’s implementation of Solvency II, is the application of Solvency II principles in the United Kingdom. It is how the UK transposed Solvency II requirements into its national legislation. While it closely aligns with Solvency II, there are some specific UK adaptations and regulations that reflect the unique features of the UK insurance market.

Does CWAN support Solvency UK reporting?

Yes. CWAN supports Solvency UK reporting under the PRA framework.

Where Solvency UK diverges from EU Solvency II — such as calibration adjustments or reporting distinctions — CWAN applies jurisdiction-specific logic to reflect applicable requirements. This allows insurers operating across EU and UK entities to manage reporting within a unified capital infrastructure.

What aspects of Solvency II does CWAN support?

CWAN supports:

  • Standard Formula SCR calculations for investment-related risk modules
  • Aggregation of capital charges using prescribed correlation matrices
  • Investment-related Pillar 3 Quantitative Reporting Templates (QRTs)
  • Built-in validation controls aligned to regulatory requirements
  • Full audit traceability across calculation and reporting workflows

This enables insurers to manage capital calculations and supervisory reporting within a controlled, defensible framework.

Does CWAN support Solvency II reporting across all EU member states?

Yes. Solvency II is an EU-wide regulatory framework. CWAN supports Solvency II reporting requirements applicable across EU member states, including:

  • Investment-related SCR calculations under the Standard Formula
  • Pillar 3 investment Quantitative Reporting Templates (QRTs)
  • Built-in validation controls and audit traceability

Jurisdiction-specific supervisory interpretations (e.g., local regulator guidance) are addressed as part of regulatory scoping and implementation.

How does CWAN support multi-jurisdiction regulatory reporting?

Where firms operate under multiple capital regimes simultaneously, CWAN enables consistent data integrity and control standards while applying the distinct methodologies required by each supervisory authority. CWAN supports multi-jurisdiction reporting by:

  • Maintaining a centralized investment data model aligned to regulatory classification requirements
  • Applying jurisdiction-specific capital calculation logic where applicable
  • Supporting region-specific reporting templates and outputs
  • Preserving validation workflows and audit trails across reporting regimes
  • Enabling reporting-period version control and traceability
Can prior submissions be reproduced exactly as filed?

CWAN maintains reporting-period version control and preserves historical snapshots of calculation inputs, validation results, and QRT outputs. This allows insurers to reproduce prior submissions with full traceability for audit and supervisory review.
