We have a commercial customer who opened an LLC less than 30 days ago using loan proceeds secured by a CD with our bank. His business is electrical contracting. Within three weeks the first check to potentially overdraw the account was returned due to NSF. He had promised to make a cash deposit to cover that item but did not show up (hence the return). In the last 6 business days he has deposited cash totaling $50K+. It is hard for me to conceive of a one-member LLC electrical contractor conducting a cash business. Do the facts require an SAR?
