Answer: Credit card ABS

## Explanation Credit card ABS (Asset-Backed Securities) typically use a revolving structure because: - **Revolving nature of credit card receivables**: Credit card balances constantly change as consumers make purchases and payments - **Amortization structure**: Credit card ABS have a revolving period where principal collections are used to purchase new receivables rather than paying down investors - **Lockout period**: During the revolving period, only interest payments are made to investors - **Amortization period**: After the revolving period ends, principal payments begin This structure allows the pool of credit card receivables to maintain a relatively stable size during the revolving period, which is essential given the dynamic nature of credit card balances. Other types of ABS mentioned: - **Auto loan ABS**: Typically have fixed amortization schedules - **Student loan ABS**: Usually have scheduled amortization - **Mortgage-backed securities**: Have predetermined payment schedules - **Collateralized debt obligations**: Structure varies but not typically revolving - **Commercial mortgage-backed securities**: Fixed payment schedules The revolving structure is particularly suited for credit card ABS due to the revolving nature of the underlying credit card accounts.
