What is Customer Due Diligence (CDD)?

Customer due diligence is the process of proof checking your customers' information and background to verify their identity and assess the level of risk involved in conducting business with them. The customer due diligence process requires organisations to collect important customer information like their name, address, occupation, and how they plan to use their account.

To meet customer due diligence requirements, information provided by the customer is fact-checked against official records and databases such as passport, utility bill, driver’s license, etc. Basically, this helps the firm understand what type of customer they are and the related anti-money laundering (AML) and combating financing terrorism (CFT) risks they pose. Globally, all Financial Action Task Force (FATF) member countries have to implement CDD checks domestically as part of their larger scope of AML and CFT goals.

What are the basics of Customer Due Diligence (CDD)?

The Customer Due Diligence process is guided by three foundational rules. They include:

1. Identifying customers

This is the first and most basic step of the Customer Due Diligence process. It involves customer due diligence checks that is, the company collecting personal information from its customers through accepted IDs. Data to be collected include address, passport, name, photographic ID card, and more.

2. Establishing business relationship

In this process, the company establishes the nature and purpose of the business relationship which they are creating with the customer.

3. Establishing beneficial ownership

Here, the company seeks to establish the identity of the ultimate beneficial ownership (UBO) when the customer is acting on behalf of a third party. The UBO simply refers to the individual or group that benefits from the activities of the customer.

When is Customer Due Diligence (CDD) Required?

Customer Due Diligence (CDD) is required when an organisation falls under the AML/ CFT regulation. This means it has to conduct identity verification on potential customers to assess their risk profile.

The organisation is required to undergo these CDD measures and KYC steps for these situations:

1. Suspicion of financial crimes:

If the customer is suspected of terrorism financing or money laundering.

2. Occasional Transactions:

There are certain transactions that necessitate CDD measures. For example, this could apply to high-risk transactions or amounts of money over a certain limit.

3. Ongoing monitoring:

Although CDD starts with a process, it doesn't end there. It is not a one-time obligation, therefore, companies are required to frequently perform CDD at different times in the business-customer relationship to ensure the customer is compliant with their established risk profiles.

4. Untrusted Documentation:

This is a situation wherein the custom provides an unreliable identity KYC document for verification. In such a situation, CDD should be applied.

By applying these steps, firms stay aligned with customer due diligence best practice and regulatory standards.

Is Know Your Customer (KYC) the same as Customer Due Diligence (CDD)?

No, KYC is not the same as CDD. KYC is one of the processes involved during client due diligence, while CDD is the overall process that both identifies the customer and assesses the risks involved in doing business with them.

What is the difference between KYC and CDD?

The major difference between KYC and CDD is that KYC is one of the processes organisations carry out to prove that they have satisfied CDD. CDD itself is the overall system that both verifies and identifies risks surrounding the business-customer relationship.

Step-by-step process on how to perform Customer Due Diligence (CDD)

Customer due diligence best practice requires institutions to take this flexible approach.

Therefore, although the customer would face their standard CDD procedure, which largely means identity verification, more strict or less stringent processes could be applied for customers that pose higher or lower risks.

As a rule of thumb, the following processes must be included in a company’s risk assessment procedure:

Standard risk assessment that takes into account the risk variables surrounding the business-customer relationship.
Money laundering procedures and policies that incorporate the firms' risk assessment.
Internal audit teams to robust test internal policies, procedures and adequate controls as required.
Continuous training and monitoring of personnel on how to carry out risk-based CDD.

Examples of these clients are Politically Exposed Persons (PEP) or corporations from high-risk nations.

EDD is used by businesses to protect themselves and satisfy compliance requirements. During the EDD, qualified specialists should be consulted to avoid mistakes and time-wasting. a combination of EDD an CDD measures ensures you are fully compliant and better protected from financial crime.

What is Ongoing Monitoring?

Ongoing monitoring strengthens client due diligence by keeping track of transactions, storing client data, and ensuring that activities remain consistent with the customer’s established risk profi

The following actions are carried out during ongoing monitoring:

Keeping records, data, documents, and important client information for CDD purposes.
Monitoring transactions throughout the duration of the business-customer relationship to ensure a client's activities correspond to their risk profile.
