  Credit risk area is one of the most rapidly developing areas of
  finance. Constantly appearing new credit instruments as well as
  increasing volume of transactions produce great demand for models
  that could help to value and manage the risk. The existent credit
  migration models, however, have a number shortcomings, which make
  them not very useful in practice.  We propose a model, which
  mitigate many of those problems.  Examples of the model use are
  dynamic pricing of some credit derivatives as well different risk
  management applications.
