I was doing some reading to try and answer a question concerning Reg U and just would like to confirm an understanding (or perhaps a misunderstanding). If the borrower is securing a loan in an amount that exceeds $100,000 by margin stock, Reg U applies in that the bank must complete Part I and Part III of FR U-1. This is regardless of the purpose of the credit. If the purpose of the loan is to purchase or carry margin stock, then part II is required. If the loan involves margin stock as collateral, Reg U will apply in some manner regardless of the purpose. Is that a correct understanding? Also I would like to understand "indirectly secured". If the loan is secured by a trust account and the trust does contain margin stock, is this considered indirectly secured and will Reg U be applicable? Thank you for your help.
