1. A system for valuing a credit hybrid, the system comprising: at least one processor; and at least one computer readable memory unit in communication with the at least one processor, wherein the at least one memory unit comprises computer instructions which, when executed by the at least one processor, cause the at least one processor to calculate a value for the credit hybrid based on a forward hazard rate model that models the forward hazard rate based on a stochastic differential equation that includes a jump term for the hazard rate, wherein the jump term is based on a non-negative function of the hazard rate and a discontinuous process and wherein the stochastic differential equation additionally includes a drift term for the hazard rate and a Brownian motion term for the forward hazard rate, and wherein the stochastic differential equation is: 
 dh tT =μ tT h dt+σ tT h dB t h +G ( h tT ) dN t where T is the maturity of a corresponding hazard rate, μ tT h is a drift term, σ tT h is a hazard rate volatility, B t h is a continuous-time Brownian motion function, G(h tT ) is a non-negative function of the hazard rate h tT , and N t is a discontinuous process with frequency λ, and G(h tT )dN t is the jump term.
