(iii) a willful violation which was intended to mislead the person to whom the credit was extended. Notwithstanding the preceding sentence, except where such disclosure error resulted from a willful violation which was intended to mislead the person to whom credit was extended, an agency need not require such an adjustment if it determines that such disclosure error:
(aa) resulted from an error involving the disclosure of a fee or charge that would otherwise be excludable in computing the finance charge, including but not limited to violations involving the disclosures concerning consumer credit insurance, property and liability insurance, and official fees, in which event the agency may require such remedial action as it determines to be equitable, except that for transactions consummated after two (2) years following March 31, 1980, such an adjustment shall be ordered for violations of disclosure of consumer credit insurance,(bb) involved a disclosed amount which was ten percent (10%) or less of the amount that should have been disclosed and in cases where the error involved a disclosed finance charge, the annual percentage rate was disclosed correctly, and in cases where the error involved a disclosed annual percentage rate, the finance charge was disclosed correctly; in which event the agency may require such adjustment as it determines to be equitable,(cc) involved a total failure to disclose either the annual percentage rate or the finance charge, in which event the agency may require such adjustment as it determines to be equitable, or(dd) resulted from any other unique circumstance involving clearly technical and nonsubstantive disclosure violations that do not adversely affect information provided to the buyer, debtor or lessee and that have not misled or otherwise deceived the buyer, debtor or lessee. In the case of other such disclosure errors, each agency may require such an adjustment.
