<abstract displayLabel="Summary">Credit risk factor models tend to have a narrow focus on the Gaussian case, use copula functions that don't work well with the martingale methods used in pricing, and can introduce arbitrage. Dariusz Gatarek and Juliusz Jablecki show how an increasing sequence of default times can be used to create systematic factors that allow for a rich correlation structure - and keep strong links with pricing </abstract>
