If we use a lobby banner to advertise account bonuses, would we have to provide additional disclosures on the banner itself?

Regulation DD states that indoors signs (“inside the premises of a depository institution”) are not subject to the additional disclosures ordinarily required when advertising a bonus. 12 CFR 1030.8(e)(2). Of course, you must ensure that the sign is not “misleading or inaccurate.” 12 CFR 1030.8(a).
