Fixed Income NonAmortizing Asset

Does anyone have idea about that nonamortizing asset has clean up call provision? I thought only amortizing asset have cleanup call provision and nonamortizing like credit card recievale have early or rapid amortization.

Yeah see los 58c. Applies to non amortizing assets with revolving structure during the lockout period. allows for early triggering of principal payment

CFAI book says cleanup call provision is for Amortizing assets.
