Quote from logic_man:
Dude, you are making valid points but you are assuming too much (unless you know things for sure). In this case, you are assuming that U.S. Bank will give out that information over the phone. The NFA might only be empowered to obtain that information via mail.
If I call U.S. Bank and say "I'm with the NFA, can you tell me how much is in the account for PFG?" are they automatically going to give me that info? Yes, they might, if I have some kind of corroborating access code or account number or something, but they also might say, "You have to request that information in writing or in person".
If the compliance documents specify only one method of information exchange, no other method is going to get you the info.
One thing I've learned on a couple of process design projects I've done is that you should never assume that the process works the way you think it should work or the way you would design it to work.
