CUSTOMER DUE DILIGENCE (CDD) — STANDARD MEASURES
Required for all customers at account opening:
- Identify the customer — obtain identifying information
- Verify the customer's identity — using reliable, independent source documents
- Identify the beneficial owner (BO) — persons owning or controlling ≥ 25% (or lower)
- Verify the beneficial owner's identity
- Understand the nature and purpose of the business relationship
- Conduct ongoing monitoring of the relationship
Individual Customer Identity Verification
Documents (in order of reliability): Tier 1 (highest): Passport; national ID card; government-issued photo ID Tier 2: Driving licence; residence permit Address verification: Utility bill, bank statement, government correspondence (must be dated within 3 months) For non-face-to-face onboarding: certified copies; electronic verification; video identification (where jurisdiction permits).
Corporate Customer Identity Verification
Company: Certificate of incorporation; memorandum and articles of association; latest audited accounts; register of directors; register of shareholders Beneficial owner: Identify all individuals owning or controlling ≥ 25% (FATF threshold — some jurisdictions use lower: 10% in USA for certain entities) Director verification: Verify identity of all directors with day-to-day control Authorised signatories: Verify identity of all authorised signatories
Understanding Business Purpose
Document: Nature of business; anticipated transaction types, volumes, and values; source of funds for specific transactions; geographic profile of activity. Risk-proportionate: More detail required for higher-risk customers and products.
POLITICALLY EXPOSED PERSONS (PEPs) — ENHANCED DUE DILIGENCE
PEP Definition (FATF Recommendation 12)
Individuals entrusted with prominent public functions:
- Heads of state, heads of government, senior politicians
- Senior government officials, judicial or military officials
- Senior executives of state-owned enterprises
- Senior officials of political parties
PEP Classifications
Tier 1 — Foreign PEP: Individual holding prominent function in foreign country. Mandatory EDD under FATF. Highest risk. Tier 2 — Domestic PEP: Individual holding prominent function in the bank's home country. EDD required under 5AMLD (EU) and most jurisdictions. Moderate-high risk. Tier 3 — International Organisation PEP: Senior officials of international organisations. EDD required under 5AMLD. Moderate risk. Family members and close associates: Treated as PEPs for EDD purposes.
Duration of PEP Status
PEP status does not automatically end when the individual leaves office. FATF guidance: risk-based approach — senior positions warrant longer post-tenure treatment. Minimum: 12-month post-tenure review period. Best practice for senior officials (heads of state, senior ministers): 2–5 years. Bank must document why the individual's risk has reduced to non-PEP level before downgrading their status.
PEP EDD Requirements
a) Senior management approval (minimum: Head of Business, often CRO level) b) Source of wealth — understand how the individual accumulated their wealth (not just source of funds for this transaction) c) Source of funds — specific source of funds for this relationship/transactions d) Enhanced ongoing monitoring — more frequent and more detailed transaction review e) Annual or more frequent risk review of the relationship
Source of Wealth vs. Source of Funds
Source of wealth: How did this person accumulate their total net worth? Evidence: Business ownership documents; pay slips; investment records; inheritance documentation; property sales; prior wealth disclosures. Source of funds: Where do the specific funds entering this account come from? Evidence: Bank transfer confirmations; investment sale proceeds; salary receipts. Both are required for PEPs and high-risk customers. Vague assertions ("business income") without documentary evidence are NOT sufficient for EDD.
ENHANCED DUE DILIGENCE (EDD) — HIGH RISK CUSTOMERS
Triggers for EDD
- PEP status (mandatory)
- High-risk jurisdiction (FATF grey/black list, high TI Corruption Perceptions Index)
- Complex corporate structure (offshore holding company, nominee directors)
- High-value or complex transactions inconsistent with declared profile
- Adverse media or negative information during screening
- Non-face-to-face onboarding for high-value relationships
- Correspondent banking (FATF Rec 13 — specific requirements)
EDD Process
- Gather more detailed information (source of wealth, source of funds, BO structure)
- Verify information using independent sources (not just what customer provides)
- Senior management sign-off (written approval, documented)
- Enhanced ongoing monitoring (more frequent transaction reviews, lower alert thresholds)
- Annual EDD refresh (minimum) — re-verify key information
SIMPLIFIED DUE DILIGENCE (SDD)
Permitted in limited circumstances where risk is demonstrably low:
- Listed companies on regulated markets (public ownership = transparency)
- Government entities (inherently low money laundering risk)
- Supervised financial institutions (subject to AML regulation themselves) Do NOT apply SDD automatically — must assess risk and document justification. SDD does NOT eliminate the need for ongoing monitoring.
ONGOING MONITORING
All customer relationships require ongoing monitoring:
- Transaction monitoring (automated TM system — see aml-typologies.md)
- Periodic KYC refresh (frequency based on risk rating): High risk: annual or more frequent Medium risk: every 2–3 years Low risk: every 3–5 years
- Trigger-based refresh: adverse media, change in ownership, change in business, large unusual transaction, law enforcement contact
BENEFICIAL OWNERSHIP — COMPLEX STRUCTURES
The Look-Through Principle
For complex corporate structures (holding companies, trusts, foundations): Look through the corporate layers until you identify the natural person(s) who ultimately own or control the customer entity.
- Ownership: direct + indirect shareholdings aggregated ≥ 25%
- Control: right to appoint/remove majority of directors; shareholder agreement giving effective control below 25% formal threshold
Offshore / Secrecy Jurisdictions
Cayman Islands, BVI, Panama, Isle of Man, Jersey, Guernsey: register of members may be private. The bank must still obtain BO information. Options: Obtain certified copy of private register from registered agent; obtain written declaration from customer with supporting documentation; where documentation cannot be obtained: CANNOT onboard or must apply enhanced risk mitigation with documented rationale.
Trust Structures
Identify: Settlor; trustee(s); protector(s); beneficiaries (or class of beneficiaries). Verify: Identity of all controlling parties and beneficial owners of > 25%.
NEVER DO THESE
- NEVER approve SDD without a documented risk assessment — SDD is not the default, it requires demonstrable low risk
- NEVER accept "business income" as sufficient source of wealth evidence for PEPs — documentary evidence of how wealth was accumulated is mandatory
- NEVER onboard a customer when beneficial ownership cannot be established through the full corporate chain — if BO is opaque, the relationship must be declined or escalated to senior management with documented enhanced risk mitigation
- NEVER downgrade a PEP's risk status immediately upon leaving office — a minimum 12-month post-tenure review period is required, and senior officials require 2-5 years
- NEVER treat CDD as a one-time onboarding event — ongoing monitoring and periodic refresh (frequency per risk rating) are mandatory for the life of the relationship
ALL OUTPUTS REQUIRE REVIEW BY A QUALIFIED PROFESSIONAL BEFORE USE IN REGULATORY FILINGS OR BUSINESS DECISIONS.
