Model Assurance Services

hero image

Trust can be hard to earn, especially with complicated and complex businesses and processes. As the models that companies develop and use also become more complex, stakeholders are increasingly holding companies responsible for their fairness and effectiveness. PwC’s Assurance Services team can help build trust. Our group of multidisciplinary subject matter specialists have trusted frameworks as well as emerging methods and tools to help provide stakeholders with an independent opinion on these critical models and processes.

66% of CEOs say stakeholder trust concerns have arisen in at least one area of business operations over the last 12 months.

Model Analysis and Assessments

Model Analysis

We deliver independent testing, assessment, analysis, and monitoring of insurance models—including pricing, valuation, capital, and FP&A models—to enhance performance, reliability, and regulatory alignment. Engagements often include independent reperformance and review of methodologies and controls to establish confidence in results.

Assumptions Assessment

We provide independent testing and assessment of the assumptions and data that drive model results, including how they’re developed, supported, approved, and monitored over time. This helps strengthen governance and maintain transparent, reliable inputs that stakeholders can trust.

Outcome Testing

We conduct outcome testing and monitoring to assess model performance across scenarios and segments and identify unintended impacts. For AI/ML models, this includes bias-focused testing to establish trust, transparency, and ongoing performance.

Insurance Regulation and Actuarial Opinions

US Insurance Regulation Assistance

We translate NAIC and state requirements into actionable model and governance practices. Expertise includes VM‑20, VM‑21, and VM-22; PBR documentation; asset adequacy testing and AOM; LDTI controls and disclosures; RBC and ORSA integration; and fairness for accelerated underwriting. We deliver gap assessments, remediation, and regulator‑ready documentation and training.

Bermuda and Cayman Regulation Assistance

We prepare life insurers for BMA EBS and BSCR model governance and proportionate CIMA expectations. Services include inventories, documentation suites, independent analysis, internal audit coordination, and supervisory engagement support. Our jurisdiction‑specific frameworks and reports reduce regulatory friction and build board and regulator confidence.
