(2) Such regulations may exempt from the provisions of this subchapter any class of transactions that are not primarily for personal, family, or household purposes, or business or commercial loans made available by a financial institution, except that a particular type within a class of such transactions may be exempted if the Board determines, after making an express finding that the application of this subchapter or of any provision of this subchapter of such transaction would not contribute substantially to effecting the purposes of this subchapter.

In no event shall such records or data be maintained for a period of less than one year. The Board shall promulgate regulations to implement this paragraph in the manner prescribed by chapter
5 of title
