Answer:
Reg U requires that whenever a bank extends credit secured directly or indirectly by any margin stock, in an amount exceeding $100,000, the bank shall require its customer to execute Form FR U-1. Security in a brokerage account that contains marginable securities would qualify. Closely held stock is not marginable and therefore a Form FR U-1 would not be required.
