Under Reg O are there any ramifications on a credit card of an Insider that is over its limit? Assuming we allow other credit card holders to go over the limit, are there any restrictions in Reg O against it? It seems like an "overdraft" but it does not fit the OD definition in Reg O because it is not in excess of funds in a deposit account. It just seems wrong, but I can't find anything in the regulation. We do charge normal interest to the Insider as we would any other account.
