In your financial institution, there are customers who are a couple, Tim and Jane, and their sons Jerry (17 years old) and Justin (15 years old). Tim works as a director at NS (Nederlandse Spoorwegen), and Jane works at WHO (World Health Organization). Jerry, out of interest, imports a certain type of drone from China and resells it to Turkey. Transactions are made via SWIFT, and from the invoice provided, you cannot determine the end buyer. Meanwhile, Justin makes an exceedingly high number of cash deposits every week. How would you approach conducting customer due diligence (CDD) and ongoing monitoring for each of them? Please note that applicable law is Dutch law.
