Abstract:
1. A method for computing a migration and performance matrix using a data processing system, the method comprising: electronically receiving a selection of rated entities from a user; electronically retrieving, from a database, mass data for the selected entities for a rating period; reading ratings and utilizations for the selected entities at a beginning and an end of the rating period to create a base matrix before aggregation, wherein the base matrix before aggregation provides a basis for completing the migration and performance matrix; reading at least one of an inflow and an outflow status for a rated entity, wherein the inflow or outflow status indicates whether the rated entity is new to a portfolio, has been part of the portfolio, or has left the portfolio; storing the inflow or outflow status in the base matrix before aggregation; comparing, by a processor, ratings of the selected entities at the beginning of the rating period with ratings of the selected entities at the end of the rating period to determine rating migrations for the selected entities of the base matrix before aggregation; arranging an order of the selected entities, which are listed in the base matrix before aggregation, according to the rating migrations; forming a base matrix after aggregation based on the arranged base matrix before aggregation; and storing the base matrix after aggregation in memory of the data processing system.
