Financial firms increasingly use models bought from vendors. Widespread use of vendor models poses unique challenges for model risk management activities. Expertise about a purchased model is external to a client firm, but model risk must nevertheless be managed by the client using the same standards applied to models built in-house. Cooperation by the vendor in certain elements of model risk management is therefore a necessity. Clients and vendors benefit from a common understanding of how vendors can be helpful, which is why the GARP Risk Institute acted as secretariat for a working group of representatives from major financial firms represented on GARP's Buy Side Risk Management Forum to produce a downloadable guide for model vendors and their clients. The document specifies resources that clients may need vendors to provide to support their risk management of vendor models.
Vendors may use the document to better understand the needs of clients, bearing in mind that the relevance of each element of the document will vary across client-vendor pairs. Clients may wish to use the document as part of their contracting for models, modifying it as appropriate to fit their situation.
The contents of the document are likely to be applicable not only to asset managers but also to banks, insurers and any other financial firm that manages model risk. As experience acculumates, the document may change from time to time.
Members of the working group include:
