Model Validation Solutions

CompatibL offers independent validation services across a wide range of valuation and risk models, including formal regulatory validation reports as well internal reviews with actionable insights to mitigate models’ weaknesses and limitations. We have expertise in the latest quantitative research and model validation methodologies as well as implementation practices.  

Regulatory Validation Services

A transparent and independent model review process is an integral part of modern model vetting and model risk frameworks. 

CompatibL has hands-on experience and expert judgement in all aspects of model QA and review processes. We validated hundreds of models and software solutions for banks and asset managers across multiple model types with applications to valuation and risk management.

CompatibL’s regulatory expertise spans real-world and risk-neutral multi-factor and multi-asset risk models for most asset classes including interest rates, foreign exchange, equity, inflation, credit and commodities.

Validation Steps

CompatibL’s approach to model validation and verification includes the following stages for a comprehensive and detailed review of the model and its components. 
  • Model
    specification stage
  • Validation
    specification stage
  • Testing stage
  • Conclusion stage
  • Delivery stage
  • Analyze model documentation, verify its consistency, level of detail and correctness
  • Analyze the relevant regulatory guidance and market practice, model choice applicability and adequacy, and propose operationally feasible alternatives
  • Identify and assess key model inputs and outputs, verify their completeness and proper use of market data for a given model
  • Identify and assess key model assumptions and limitations, then compare to other model alternatives
  • Identify and assess key validation assumptions and limitations, given input and output data and possible operational constraints
  • Review data scope, validation criteria and functional tests for model vetting based on the results from the previous stage
  • Run validation tests
  • Assess the impact of model choice on material measures
  • Analyze individual test results, provide recommendations and conclusions
  • Gather all findings into an executive summary and a highly detailed full validation report, conforming to the relevant regulatory validation template when applicable
  • Deliver validation documentation, reports, and supporting materials
  • Deliver test code artifacts and detailed documentation that allows this validation to be rerun in-house after project completion
