  • Make sure that models are fit for purpose.
  • Provide constructive, independent technical checks and challenges at committee level.
  • Perform independent reviews of new and existing models, including but not limited to capital and pricing models.
  • Understand model purpose, the underlying mathematical model, its implementation and its deficiencies. Understand the model behaviour under stress such as applied in capital calculations.
  • Undertake rigorous testing of new and existing models to assess comprehensiveness of risk representation, suitability for intended use, robustness and stability of calibrations, ongoing performance vis-à-vis risk factor and portfolio back testing, and reasonableness of simulations vis-à-vis other distributional tests
  • Apply quantitative and qualitative techniques to model validation, this can include independent implementation of the model.
  • Propose solutions to model deficiencies.

  • Benchmark particular model components such as parameter estimation methods or pricing models to justify against alternative approaches
  • Document models, methodologies, analyses, and findings.
  • Develop model performance monitoring scorecards and dashboards;
