Transforming Regulatory Reporting in a Diversified Insurance Group

A diversified insurance group offering life, non-life and health products across several markets was struggling to keep pace with evolving regulatory expectations. Solvency reporting, conduct supervision and emerging sustainability disclosures all demanded granular, high-quality data. Yet the group’s reporting processes were fragmented, with each business line maintaining its own tools and interpretations. Supervisors had raised concerns about inconsistencies between quantitative templates and narrative reports, and internal stakeholders questioned the reliability of key risk indicators. In response, the group’s executive committee decided to embark on a comprehensive modernization of regulatory reporting and compliance, with Radner’s team providing end-to-end support.

Unlike previous initiatives that focused narrowly on specific regulations, this program was designed from the outset as an integrated transformation. Radner’s team proposed a framework that would cover prudential, conduct and sustainability reporting within a single governance and data architecture. The rationale was clear: many of the underlying data elements, such as policy characteristics, claims information and investment exposures, were shared across different regulatory regimes. By addressing them holistically, the group could reduce duplication, improve consistency and respond more flexibly to future regulatory changes.

The first step was a comprehensive assessment of the current state. Radner’s team conducted workshops with representatives from actuarial, risk, finance, compliance, investments and IT. These sessions mapped existing reports, data flows, systems and controls. They also surfaced pain points, such as late data deliveries from third-party administrators, manual adjustments to actuarial outputs and limited traceability from reported figures back to source transactions. The assessment revealed that more than 40% of the effort spent on regulatory reporting was devoted to reconciling discrepancies between different views of the same data.

To create a common foundation, Radner’s team worked with the group to define a unified data model for regulatory reporting. This model captured the key entities and attributes needed for solvency, conduct and sustainability disclosures, including policies, claims, reinsurance arrangements, investments and counterparties. The model was designed to be extensible, allowing new regulatory requirements to be accommodated without fundamental redesign. By aligning stakeholders around this shared model, the group took a crucial step towards breaking down the silos that had previously hindered consistency.

With the data model agreed, attention turned to data sourcing and quality. Radner’s team performed detailed data lineage analyses for critical metrics, such as technical provisions, solvency capital requirements and investment exposures by asset class and rating. These analyses traced data from source systems in underwriting, claims and investments, through actuarial engines and data warehouses, to reporting tools. Along the way, the team identified gaps, such as missing identifiers for certain counterparties, inconsistent product codes and incomplete capture of policyholder characteristics. Addressing these gaps required coordinated action across business lines and functions.

To drive this coordination, the group established a cross-functional data governance council, with design support from Radner’s team. The council was responsible for overseeing the implementation of data quality rules, resolving ownership disputes and prioritizing remediation efforts. For example, when it became clear that missing or inconsistent counterparty identifiers were undermining both solvency and sustainability reporting, the council mandated a group-wide initiative to standardize these identifiers. This initiative involved changes to front-office systems, data migration and enhanced validation at the point of capture.

In parallel, the group needed to strengthen its reporting processes and controls. Radner’s team helped design a standardized reporting lifecycle that applied across prudential, conduct and sustainability reports. This lifecycle covered planning, data collection, calculation, validation, review, approval and submission. For each stage, roles and responsibilities were clearly defined, along with required documentation and control activities. A particular focus was placed on ensuring consistency between quantitative templates and narrative disclosures, which had been a recurring source of supervisory concern.

To support this lifecycle, the group implemented a centralized reporting platform. Radner’s team assisted in selecting and configuring the platform, ensuring that it could handle the complexity of insurance-specific calculations and templates. The platform integrated with actuarial engines, data warehouses and document management systems, providing a single environment for preparing, reviewing and approving reports. Built-in validation rules checked for internal consistency, alignment with regulatory taxonomies and adherence to business rules defined by the data governance council.

One of the most challenging aspects of the transformation was aligning actuarial and finance perspectives on key metrics. Historically, actuarial teams had focused on best estimate liabilities and risk margins, while finance teams emphasized accounting valuations and earnings. Regulatory reporting required a coherent view that bridged these perspectives. Radner’s team facilitated joint working sessions where actuarial and finance experts reconciled their methodologies, assumptions and outputs. These sessions led to the definition of a shared valuation and assumption framework that underpinned both internal and external reporting.

As the new framework took shape, the group also had to address the growing importance of sustainability-related disclosures. Supervisors and investors were increasingly interested in how insurers managed climate risks, invested in sustainable assets and treated policyholders fairly. Radner’s team helped the group identify which sustainability metrics were most relevant and how they could be derived from existing data sources. Where gaps existed, such as missing information on the energy efficiency of insured properties or the environmental profile of investments, targeted data enrichment initiatives were launched.

Training and change management were essential to embedding the new approach. Radner’s team developed a comprehensive training program tailored to different roles. Underwriters and claims handlers learned how accurate data capture affected downstream solvency and sustainability reporting. Actuaries and risk managers received training on the new data model, governance processes and reporting platform. Senior executives were briefed on how improved regulatory reporting and compliance could enhance strategic decision-making, investor communication and supervisory relationships.

Over time, the benefits of the transformation became increasingly visible. The number of late adjustments to solvency reports declined sharply, and reconciliation breaks between actuarial and finance figures were significantly reduced. Supervisory feedback shifted from highlighting deficiencies to recognizing progress and encouraging further innovation. The group was able to respond more quickly to new regulatory requirements, such as enhanced climate risk disclosures, because the underlying data and governance structures were already in place.

Internally, the improved reporting capabilities enabled more sophisticated risk and capital management. The group could analyze solvency positions by product line, geography and distribution channel with greater confidence. Scenario analyses and stress tests became more reliable, informing decisions about product design, reinsurance strategies and investment allocations. The integration of sustainability metrics into these analyses allowed the group to assess the long-term resilience of its business model under different climate and regulatory scenarios.

Operational efficiency also improved. Automation of data collection, calculation and validation reduced manual effort and the risk of human error. Reporting cycles became more predictable, with fewer last-minute crises and a more balanced workload across teams. Staff who had previously spent much of their time reconciling numbers could now focus on interpreting results and advising management. This shift enhanced job satisfaction and made the reporting and risk functions more attractive career paths within the organization.

The transformation had a positive impact on external stakeholders as well. Investors appreciated the greater transparency and consistency of the group’s disclosures, which facilitated more informed assessments of risk and performance. Rating agencies noted the strengthened risk management and reporting capabilities in their analyses. Policyholders and distribution partners benefited indirectly from the group’s improved understanding of its risk profile, which supported more sustainable product offerings and pricing.

In the final phase of the engagement, Radner’s team supported the group in conducting a comprehensive self-assessment against supervisory expectations for regulatory reporting and compliance. This assessment covered governance, data, systems, processes and controls across prudential, conduct and sustainability domains. The results confirmed that the group had made substantial progress, while also highlighting areas for further enhancement, such as deeper integration of climate scenario analysis and more granular conduct risk metrics. A multi-year roadmap was agreed to continue evolving the framework in line with regulatory and market developments.

For the insurance sector, where long-term promises and complex risks are central to the business, this case illustrates the strategic value of robust regulatory reporting and compliance capabilities. By modernizing its data architecture, governance, processes and tools, the group not only met supervisory expectations but also gained a more comprehensive and forward-looking view of its risk and capital position. The work led by Radner’s team turned regulatory reporting from a fragmented, reactive activity into a coherent, proactive and value-adding function.

The experience of this diversified insurer shows that when regulatory reporting and compliance are approached as an integrated, cross-functional endeavor, they can support innovation, resilience and trust. In an environment of evolving solvency, conduct and sustainability requirements, such capabilities are not merely a cost of doing business; they are a foundation for long-term success.
