Are these areas required on a monthly basis or can this be included in the annual mailing as well?
In order to determine the adequacy of you language and delivery method, you need to identify what authority (if any) governs these notices. That could be federal regs (of which I have no recollection), state or local law/regulation/ordinance, or your internal policy. If policy is the only thing requiring these notices, then you should determine who was your policy maker and go sit down with that person and ask for an explanation of this self-imposed requirement.
