On valuing corporate debt with the volatility of corporate assets evolving according to an Ornstein-Uhlenbeck process


  • Bakhodir Ergashev

    (Washington University in St. Louis)


In this paper the problem of valuing corporate debt with possibility of default is considered. It is assumed that the volatility of the value of a firm's assets evolves according to an Ornstein-Uhlenbeck process and default occurs only if the value of corporate assets falls below an exogenously specified, time dependent barrier. In the case of a particular choice of default barrier the explicit formulas for the present value of a corporate debt, the total value of the firm, the value of equity, the expected default time and the variation of default time are derived.
