Auto Loans are always amortizing - credit cards are non-amortizing. In reference to the statement above, recent legislation has required that the min due construct change to allow a card holder to pay down part of their balance every month. However, the CFA text on ABS makes no mention of the new legislation, and so it shouldnt be required on the exam. That’s not to say they couldnt ask a question on it. Prior to the legislation, the min due construct varied by card issuer.
Prepayments exist on auto loans due to trade-ins, etc. The question that CFAI text brings up is does prepayment risk actually exist (ie should you use zspread or OAS for discounting purposes) - their point is that the *characteristic* of auto loans is that the option to prepay is there, but its not taken advantage of.
The point is that for auto loans zspread and OAS should be the same. The call option exists, but since it tends not to be exercised there is no value to the call option held by the borrower
