According to the ACAMS CAMS Study Guide, 6th Edition, Chapter 2, Section 2.1, the AML program should be reassessed periodically or when there are significant changes in the business environment, such as:

Expansion of business to new territories: This could expose the business to new risks, regulations, and customers that require different AML policies, procedures, and controls. The AML program should be updated to reflect the new jurisdictions and their AML requirements, as well as to conduct appropriate risk assessments and due diligence on the new markets and customers.

New product offering: This could introduce new vulnerabilities, opportunities, and challenges for the AML program. The AML program should be revised to incorporate the new product features, benefits, and risks, as well as to ensure compliance with any applicable AML rules and standards for the new product.

The other options are not factors that would necessarily lead to a reassessment of the current AML program, unless they have a material impact on the AML risks, objectives, or performance of the business:

Appointment of a new Chief Financial Officer: This could affect the AML program if the new CFO has a different vision, strategy, or approach to AML than the previous one, or if the new CFO has a significant role or responsibility in the AML program. However, the appointment of a new CFO alone does not trigger a reassessment of the AML program, unless there are other changes or issues that warrant a review.

Change of company name: This could affect the AML program if the change of name reflects a change of ownership, structure, or nature of the business that could alter the AML risks, obligations, or expectations. However, the change of name alone does not necessitate a reassessment of the AML program, unless there are other implications or consequences that affect the AML program.

Change of internal audit team members: This could affect the AML program if the new internal audit team members have different qualifications, skills, or experiences than the previous ones, or if the new internal audit team members have a different scope, methodology, or frequency of auditing the AML program. However, the change of internal audit team members alone does not require a reassessment of the AML program, unless there are other factors or findings that indicate a need for a review.
