The Board, in consultation with the other Federal banking agencies (as that term is defined in section
1681a of this title) and the Federal Trade Commission, may promulgate regulations to implement this subsection, including specifying the format for posting the agreements on the Internet sites of creditors and establishing exceptions to paragraphs (1) and (2), in any case in which the administrative burden outweighs the benefit of increased transparency, such as where a credit card plan has a de minimis number of consumer account holders.
