Where are Credit Card Rates Disclosed

Is there any requirement to disclose the specific rates used to calculate purchase, balance transfer, and cash advance APRs in the credit card agreement, if that information is already clearly disclosed with all other required pricing information (as defined in Reg Z 1026.6(b)(2)(i) through (b)(2)(xii))? This is already provided on our Interest Rates and Fees Disclosure form provided to the applicant with the card. For example, our credit card agreement (a separate document from the Interest Rates and Fees Disclosure) includes "For the non-promotional purchase and balance transfer APR, we add X.XX% to the Prime Rate. For the cash advance APR, we add XX.XX% to the Prime Rate. However, all of this information is also disclosed on our Interest Rates and Fees disclosure, which is given to the applicant with the Account Agreement and card.
