Would a change to cash collateral securing an already exisiting loan to a board member that occurred prior to any approval be a violation of Reg O? We would not allow for any modification to cash collateral to be made without approval (management, credit committee, board or otherwise) for a client - but we did for the board member. Reg O speaks very specifically to extending credit to insiders but I cannot find where it addresses "modifications, adjustments, servicing" type matters on already exisiting credits.
