Once it has been determined that funds need to be blocked, they must be placed into an interest-bearing account on your books from which only OFAC-authorized debits may be made. The blocking also must be reported to OFAC Compliance within 10 business days. Some banks have opted to open separate accounts for each blocked transaction, while others have opted for omnibus accounts titled, for example, "Blocked Libyan Funds." Either method is satisfactory, so long as there is an audit trail which will allow specific funds to be unblocked with interest at any point in the future.
