Abstract

A computer implemented method that merges historical debtor placement data and historical credit data according to a bivariate analysis to create model of debtor behavior. The model is adapted for processing current debtor placement data and credit data to value a debt portfolio or determine a probability of payment and/or estimate of payment of individual debtors.

13. The method of claim 1, further comprising:

using the probability of payment model to process current customer placement data and current credit data associated with a second debt portfolio to determine thereby a probability of payment for each of at least one account in the second debt portfolio.

14. The method of claim 13, wherein:

each account of the second debt portfolio is associated with a collection score calculated as its respective probability of payment multiplied by 100; and

a Collection Score for the second debt portfolio is calculated as the sum of all the collection scores.

15. The method of claim 13, further comprising:

establishing a collection rating as a function of the probability of payment for the accounts in the second debt portfolio.

16. The method of claim 15, wherein the probability ratings of the accounts in the second debt portfolio are divided into a plurality of ranges.

17. The method of claim 16, wherein the ranges are determined using a bell curve, division into deciles, Fibonacci sequences of the score interval endpoints or a Jenks optimization method.

18. The method of claim 3, further comprising:

using the expected monetary amount model to process current customer placement data and current credit data associated with a second debt portfolio to determine thereby an expected conditional sum of payments for each of at least one account in the second debt portfolio.

19. The method of claim 18, wherein:

each account of the second debt portfolio is associated with a Monetary Score calculated as its respective expected payment amount; and

a Monetary Score for the second debt portfolio is calculated as the sum of all the Monetary Score.

20. The method of claim 18, further comprising:

establishing a monetary rating as a function of the expected payment amounts for the accounts in the second debt portfolio.

21. The method of claim 20, wherein the monetary ratings of the accounts in the second debt portfolio are divided into a plurality of ranges.
