Model governance plays an important role in the development and management of model inventories, and this comment letter highlights resources that support robust and practical approaches to that work. The American Academy of Actuaries’ Cross-Practice Risk-Based Capital (RBC) Task Force wrote the letter to provide comments on the Aspirational Model Governance Exposure and offer additional material for consideration. The letter discusses the relevance of Actuarial Standard of Practice (ASOP) No. 56—Modeling and the Model Risk Management Practice Note (May 2019). It describes how the practice note relates to model governance, model inventories, and model risk concepts, and explains its potential usefulness in supporting the aspirational goals discussed in the exposure.
