Anti-money laundering (AML)
- Firms verify customers’ identities under a customer identification program (CIP).
- Currency transaction reports (CTRs) are filed for cash transactions over $10,000 in a day.
- Suspicious activity reports (SARs) are filed for transactions that look like money laundering or other crimes, without telling the customer.
- Structuring, breaking up cash deposits to avoid the $10,000 reporting threshold, is illegal.
