Model Risk

​Protiviti’s Model Risk professionals help management and boards of directors understand the value – and limitations – of their models so they can make confident business decisions, advance business strategies and achieve regulatory compliance.

Models are simplified and idealized representations of the real world and are prone to errors in some cases. Further, because models are driven by assumptions and finite data inputs and then interpreted by people, model risk is inescapable. The use and reliance on quantitative models creates the need to consider the degree to which model risks are understood, monitored and managed. Regulators mandate model validation under such pronouncements as OCC 2011-12/FRB SR 11-7 and comparable regulatory guidance. Other stakeholders, such as auditors, investors and rating agencies, are also demanding improved governance over the ever-expanding inventory of quantitative models.

Our Model Risk team brings Ph.D.-level “quant” experience to developing and validating all types of quantitative models, including asset-liability management, credit risk, economic capital, market risk, pricing and operational risk models. We also validate AML transaction monitoring systems and Fraud models.  Our independent, holistic validation process helps control model risk, prevents losses associated with model risk and enhances key stakeholders' understanding of models. We also help organizations manage their portfolio of model risks by assessing, designing and implementing model governance programs. We can develop customized quantitative models, refine and calibrate existing models, and design stress testing and scenario analysis programs to supplement existing analytics.
