Enhanced Know Your Customer obligations expand verification, suspicious-transaction scope, nonprofit reporting thresholds and long-term record retention requirements. Amendments require institutions to adopt enhanced KYC and due-diligence measures: identify and verify clients at account commencement, verify identity for specified transactions and international transfers, identify and verify beneficial owners, exercise ongoing due diligence, prohibit anonymous or fictitious accounts, and implement a Client Identification Programme. The rules broaden the definition of suspicious transaction to include transactions suggesting proceeds of scheduled offences, unusual complexity, lack of economic rationale, or potential terrorism financing, add definitions for non profit organisation and Regulator, mandate reporting of significant receipts by non-profits, require long-term retention of transaction records, and substitute agency-specific references with 'its Regulator.'
