The idea here is to stress-test this securitization. That is, check whether payments to investors will occur as planned even if payments by cardholders worsen along one dimension or another. This is what rating agencies do when assigning ratings. Would the securitization cover its scheduled interest payments to investors if Default Rate goes up by 75% Average Life of Receivables goes up by 75% Servicing Cost goes up by 75% Explain your assumptions. What mction does the "seller's interest" perform? Why do we see it here, and not in car- or home-loan securitizations
