One reminder for you who will include a cover letter and/or FAQ that further explains your customer's options --
Those accompanying documents are about 99% certain to be considered "promoting the payment of overdrafts." That triggers the special requirement for four specific pieces of information about your overdraft service under Regulation DD, §230.11(b).
John, I know this may be splitting hairs, but if the FAQs are not being sent to "prospective customers" and they are not promoting another account to an existing customer, do you think they meet the definition of "advertisement" in Reg DD? I agree that the FAQs promote the payment of overdrafts, but I'm not sure they're an "advertisement promoting the payment of overdrafts" that would trigger the disclosures under 230.11.
