We had a customer come into the bank and purchased a 90,000.00 cashier's check with cash he brought in with him. (He did not withdraw from his accounts here at the bank) The remitter reads his name only ("John Doe"). He does have a DBA with us also and in reading the intructions on completing a CTR it mentions on "Item 5. Doing Business As (DBA). If the financial institution has knowledge of a seperate 'doing business as' name , enter it in Item 5." Since this customer bought the cashier's check in his name not his DBA, do we have to enter anything in Item 5 just because we have knowledge that he has a DBA? Or, does that read that only if the transaction that triggered a CTR was done using the DBA do we have to complete Item 5? Thanks
