Model Risk Management

BOK Financial has an internal independent Model Risk Management staff that validates models to verify they are conceptually sound, computationally accurate, are performing as expected, and are in line with their intended use. Model Risk Management staff also enforces the Company's model risk governance program that defines roles and responsibilities, including the authority to levy findings requiring remediation and to restrict model usage.

Model Validation

Model validation staff maintain independence from both the developers and users of the models. Models are validated through an evaluation process that assesses the data, theory, implementation, outcomes, and governance of each scenario. Each model receives a model risk score, which determines the frequency and scope of validation activities. Validations comprise an assessment of model performance as well as a model's potential limitations given its particular assumptions or weaknesses. Based on the results of the review, the team determines whether the use case for the model is appropriate. The ultimate validation results may require remediation actions from the business line. Model validation results are communicated with one of the following three outcomes: "Approved for use," "Approved with findings," or "Unapproved."
