about the cost of open-end credit, only the annual percentage rate
or rates shall be stated, except that the periodic rate or rates also

in advance because there are finance charges other than a periodic
rate, the corresponding annual percentage rate shall be stated, and
other cost information may be given.

the annual percentage rate for a sample transaction shall be stated,
and other cost information for the consumer’s specific transaction
may be given.
