According to the Financial Action Task Force (FATF) Special Recommendation IV, if financial institutions, or other businesses or entities subject to anti-money laundering obligations, suspect or have reasonable grounds to suspect that funds are linked or related to, or are to be used for terrorism, terrorist acts or by terrorist organisations, they should be required to report promptly their suspicions to the competent authorities1. This is consistent with the FATF Recommendation 20, which requires the same reporting obligation for money laundering and the financing of proliferation of weapons of mass destruction2. Reporting suspicious transactions related to terrorism is a key measure to detect, prevent and suppress the financing of terrorism and terrorist acts, and to facilitate international cooperation and information exchange.

According to the Anti-Money Laundering Specialist (the 6th edition) study guide, structuring is a technique used by money launderers to avoid triggering currency transaction reporting requirements by breaking down large amounts of cash into smaller deposits that are below the reporting threshold1. Structuring can also involve withdrawing cash in small amounts from different locations or branches to evade detection and scrutiny2. Therefore, the compliance analyst is potentially identifying structuring as the type of money laundering in this case.

According to the Wolfsberg Group's Statement on the Suppression of the Financing of Terrorism1, a compliance officer should include the following three procedures in revising an institution's CTF efforts:
Consulting applicable lists and taking appropriate actions to determine if customers appear on such lists.
This procedure is important to prevent terrorist organizations from accessing the financial services of the institution and to comply with the sanctions and regulations imposed by competent authorities. The compliance officer should implement procedures for checking the customers against the lists of known or suspected terrorists or terrorist organizations issued by relevant authorities and taking reasonable and practicable steps to verify the identity and status of the customers.
Reporting matches from lists of known or suspected terrorists to relevant authorities. This procedure is important to assist the authorities in their efforts to detect and disrupt terrorist financing and to fulfill the legal obligations of the institution. The compliance officer should report to the relevant authorities any matches from the lists of known or suspected terrorists or terrorist organizations consistent with the applicable laws and regulations regarding the disclosure of customer information.
Maintaining customer information to facilitate timely retrieval of such information. This procedure is important to enable the institution to respond promptly and effectively to the enquiries and requests from the authorities and to enhance the quality and accuracy of the customer data. The compliance officer should explore ways of improving the maintenance of customer information to facilitate the timely retrieval of such information.
