Use MathJax to format equations. Whereas efficient and relatively easy to calibrate to credit default swaps (CDS) spreads and market data, we argue that this approach should be supplemented by the structural approach familiar in multiname credit risk (e.g., in the Gaussian copula models or in many widespread credit portfolios risk assessment tools).
