We have a customer that opened an account in 2005 as Friends of John Doe. At that time he was running for office and used a EIN number. H would like to update the card and add his wife as a authorized signer. We are not aware that he has or is running for office anytime soon but last year had several deposits from labor unions. Here is the question, is he the owner and wife authorized signer or since using an EIN, the Il Deposit Documentation manual indicates that would be a committee. We are not aware of a committee. So how do we label this, an entity listing him as the owner, maybe candidate we are totally confused. Any help out there?
