According to the ACAMS CAMS Certification Study Guide, 6th Edition, one of the four pillars of an effective anti-money laundering compliance program is the training of appropriate employees on their responsibilities and the institution's policies and procedures. Training is essential to ensure that employees are aware of the risks of money laundering and terrorist financing, the applicable laws and regulations, the red flags and indicators of suspicious activity, and the reporting and record-keeping requirements. Without proper training, employees may not be able to perform their duties effectively and efficiently, and may expose the institution to legal, regulatory, reputational, and operational risks.
The other options are less serious deficiencies, but still need to be addressed and corrected. The compliance officer should have regular meetings with upper management to inform them of the current money laundering trends and the status of the compliance program, but this is not as critical as providing training to the employees. The company's anti-money laundering manual should be updated to reflect any changes in the internal controls, policies, or procedures, but this is not as urgent as ensuring that the employees are familiar with the existing ones. The company should download the most recent regulation from the Financial Intelligence Unit web site, but this is not as important as complying with the existing ones.
