randomly generating a plurality of variables within the domain of possible variables;

assigning each of the accounts with one or more of the randomly generated variables; and

determining, for each account, a corresponding account level affect using the assigned randomly generated variables.

9. An article as in claim 1 , wherein the simulating utilizes a Monte Carlo simulation approach.

10. A method as in claim 1 , wherein the simulating utilizes a Monte Carlo simulation approach.

11. A method for implementation by one or more data processors comprising:

simulating, by at least one data processor, an account level effect of the economic indicators for each of the accounts, an overall effect of the simulated account level effects approximating the portfolio level effect; and

aggregating, by at least one data processor, the simulated account level effects to enable a characterization of future risk for the portfolio of accounts.

12. A method as in claim 11 , wherein the one or more economic indicators comprise a macro-economic indicator.

13. A method as in claim 11 , wherein the one or more economic indicators comprise a micro-economic indicator.

14. A method as in claim 11 further comprising:

receiving, by at least one data processor, input defining a composition of the portfolio of accounts.

generating and displaying, by at least one data processor, at least one transition matrix that characterizes a probability of a credit score increase/decrease to predetermined score ranges as a result of the one or more economic indicators.

17. A method as in claim 11 further comprising:

receiving, by at least one data processor, input characterizing optimization criteria for the portfolio of accounts; and

identifying, by at least one data processor, a subset of accounts in the portfolio of accounts meeting the optimization criteria.
