Because of the increasing number of company insolvencies and the corre
sponding loan losses, there is a need for new methods of credit rating
with the ability to predict bankruptcies early. Employing Artificial
Neural Nets (ANN) an indicator could be developed which identifies a c
ompany crisis early, objectively and with a high reliability. The anal
ysis is based on a large and representative data set. Out of a great n
umber of predictor variables that combination of variables has been de
termined best classifying companies into failed and non-failed classes
. For this purpose a backpropagation net and pruning algorithms have b
een used. The results of the developed ANN are plausible and easy to i
nterpret. In credit investigation ANN can be adapted to the parameters
of a bank for optimal results. As a conclusion ANN are an effective t
ool to predict commercial failures.
