We present a structural credit risk model which considers stochastic correlation between the assets of the companies. The covariance of the assets follows a Wishart process, which is an extension of the CIR model to dimensions greater than one. Wishart process is an affine symmetric positive definite process, a natural extension of the Heston's stochastic volatility model. We give closed form solutions for equity options, marginal probabilities of defaults, and some other major financial derivatives. In the second part of the paper, we estimate the parameters of the model by a evolutionary algorithm. We prove a theorem which guarantees the convergence of the evolutionary algorithm to the set of optimizing parameters.
