(d)Certain transactions involving ranges of balances. For purposes of disclosing the annual percentage rate referred to in 160:45-5-1(g)(4) (Mail or telephone orders - delay in disclosures) and (h)(Series of sales - delay in disclosures), if the same finance charge is imposed on all balances within a specified range of balances, the annual percentage rate computed for the median balance may be disclosed for all the balances. However, if the annual percentage rate computed for the median balance understates the annual percentage rate computed for the lowest balance by more than 8 percent of the latter rate, the annual percentage rate shall be computed on whatever lower balance will produce an annual percentage rate that does not result in an understatement of more than 8 percent of the rate determined on the lowest balance. 45d/ An error in disclosure of the annual percentage rate or finance charge shall not, in itself, be considered a violation of this chapter if (1) the error resulted from a corresponding error in a calculation tool used in good faith by the creditor; and (2) upon discovery of the error, the creditor promptly discontinues use of that calculation tool for disclosure purposes and notifies the Administrator in writing of the error in the calculation tool.
46/ For purposes of paragraph (a)(3) of this section, an irregular transaction is one that includes one or more of the following features: multiple advances, irregular payment periods, or irregular payment amounts (other than an irregular first period or an irregular first or final payment).
