Credit support is computed from the class stack order in the prospectus: the share of the deal's principal balance in classes junior to the class. Interest-only classes carry a notional balance and no principal support figure. Ratings are the latest held in the dataset for each class and agency; NR means the agency shows the class as not rated, WR that the rating was withdrawn, PIF that the class has been paid in full. Any other status value is shown exactly as the agency reports it. A + after a CUSIP marks a class with companion CUSIPs in the dataset.
