In addition to definitions appearing in subsequent articles, in this title:
Such an increase or decrease may not result in the number of percentage points referred to in this subsection being less than eight (8) percentage points or greater than twelve (12) percentage points.
In determining whether to increase or decrease the number of percentage points, the Administrator shall consult with representatives of consumers, including low-income consumers, and lenders.
If any periodic payment other than the down payment under an agreement requiring or permitting two or more periodic payments is more than twice the amount of any other periodic payment, excluding the down payment, the consumer credit sale, consumer lease, or consumer loan is "payable in installments."
