Obliged entities specified in the Money Laundering Act, such as banks and insurance companies, should establish, on the basis of a risk-based approach, their own customer due diligence procedures and minimum criteria to be followed in their customer relationships. The Money Laundering Act also provides for the duty of obliged entities to identify and know their customers and, if necessary, ascertain the origin of the funds included in a transaction. Obliged entities must also monitor the development of customer relationships and the use of services as part of the arrangement of business risks and internal control. Financial services used by customers, deposits, payment transactions, investment activity or the use of insurance services, for example, are monitored accordingly. Obliged entities also have an obligation to obtain information, which means that if an obliged entity detects an unusual or suspicious transaction, it must clarify the purpose of and justifications for the transaction and consider, on the basis of the clarification obtained, whether it is appropriate to make a report to the Financial Intelligence Unit.
