Method and apparatus for an incomplete information model of credit risk
A method and apparatus for developing a structural model of credit risk that incorporates the short-term uncertainty inherent in default events is disclosed. The model is based on the assumption of incomplete information, taking as premise that bond investors are not certain about the true level of a firm's value that may trigger default. In addition, the coherent integration of structure and uncertainty is facilitated with compensators. Compensators form the infrastructure of a class of credit models that is broad enough to include traditional structural models, intensity-based models, and a great deal more. Several empirical examples are provided that compare default probabilities and credit yield spreads forecast by the incomplete information model to the output of a Black and Cox (1976) model. It is found that the incomplete information model reacts more quickly and, unlike traditional structural models, forecasts positive short-term credit spreads for firms that are in distress. It is also demonstrated that while the model is predicated on the surprise nature of default, it does not have conditional default rate.

System and method used for credit rating and based on matching of credit rate and loss given default
ActiveCN102779317ASatisfy the essential attributes of creditAvoid loansFinanceDefault rateSystem maintenance
The invention provides a system and a method used for credit rating and based on matching of credit rate and loss given default. The system is formed by a data analysis module, a system maintenance module, a data query module and a report production module. The report production module can be used for storing credit rating results, printing and previewing. The system meets a credit essential attribute that the higher the credit rate is, the lower the loss given default is and avoids the problem that an adjustment result is obtained through infinite multiple adjustment, wherein the adjustment result is the higher the credit rate is, the lower the loss given default is. Under the condition that creditors such as commercial banks understand that different credit rates correspond to default rates, the system can avoids loss caused by the fact that clients under the rate of a break-even point perform loans and reduce loan loss. According to default conditions of different credit rates, reasonable pricing for making up default risk premium is performed on financial instruments of loans, bonds and the like, and the system and the method enable creditors such as commercial banks and bond investors and social public to understand default conditions of each credit rate and perform investment decision.
