An equity line of credit shall cease being an equity line of credit subject to the provisions of this section from and after the date the loan amount is reduced below the equity line of credit's initial loan amount unless (i) the loan amount was reduced for one or more of the reasons or pursuant to one or more of the methods specified in section 226.5b(f)(2) or section 226.5b(f)(3)(vi) of Title 12 of the Code of Federal Regulations and the official commentaries and rulings issued pursuant thereto, as the same may be amended from time to time, without regard to whether that section of the Code of Federal Regulations would otherwise apply to the loan, or (ii) the loan amount was reduced at the request of the borrower because the borrower was engaged in the refinancing of a loan secured by a superior lien on the same real property and the reduction in the loan amount of the equity line of credit is no greater than the difference between the loan amount secured by the refinancing mortgage and the outstanding principle balance of the loan being refinanced.
Otherwise, no prepayment fees or penalties may be charged or collected by the bank with respect to an equity line of credit.
