Abstract
This article develops a computational method to implement the effect of imperfect information on the value of defaultable bonds. A fuzzy modeling is adopted and the numerical experiments show that an imprecise value of the stochastic underlying asset and/or the barrier triggering default have material impact on the qualitative shape of the term structures of credit spreads.
