We present a model for pricing risky debt and valuing credit derivatives that is easily calibrated to existing variables. Our approach expands a classical term-structure model to allow for multiple rating classes of debt. The framework has two salient features: (1) it uses a rating-transition...

Our approach is based on expanding the Das and Sundaram (2000) extension of the Heath-Jarrow-Morton (1990) term-structure model to allow for multiple ratings classes of debt....
