Abstract
In this chapter, we study the case of default in credit modelling. Structural models and intensity models are first covered. We then study the pricing of some basket credit products, where correlated default is the main issue.

For a portfolio with tradable transactions only, close-out risk or VaR may be used instead of PFE for the risk limit, for instance, 10 day 90% VaR.
- 4.
For instance, the 10 day 90% VaR of USD100m means that there is 10% probability that the loss will be more than USD100m for the period of 10 (business) days.
