Structuring is the practice of breaking down large amounts of cash into smaller transactions to avoid triggering currency transaction reports (CTRs) or suspicious activity reports (SARs) by financial institutions.
CTRs are required for cash deposits or withdrawals of more than $10,000 in the United States, and SARs are filed when there is a reasonable suspicion of money laundering or other illicit activity. By making multiple deposits of less than $10,000 at different tellers, the owner of the retail store is attempting to evade the reporting requirements and conceal the source or destination of the funds. This is a common technique used by money launderers in the placement stage of the money laundering process, when they try to introduce illegal proceeds into the financial system. Structuring is illegal under the Bank Secrecy Act and can result in civil and criminal penalties.

having an outdated and incomplete risk assessment could expose the financial institution to significant money laundering and terrorist financing risks that are not identified, measured, or mitigated. The risk assessment is a key component of an effective anti-money laundering program, and it should be updated regularly to reflect the changes in the business environment, customer profile, product offerings, delivery channels, and regulatory requirements12. A risk assessment that is several years old and does not cover all current products and services could fail to capture the emerging threats and vulnerabilities that the financial institution faces, and could result in inadequate or inappropriate controls, policies, and procedures. This could lead to the highest potential for unmitigated risk, as the financial institution could be exploited by money launderers and terrorist financiers, and face regulatory sanctions, reputational damage, and financial losses.

The correct answer is B, because it describes a method of money laundering known as structuring or smurfing. This is when a customer or a group of customers break down large amounts of illicit funds into smaller transactions that are below the reporting threshold, and then send them to another customer or entity, often in another country. This way, they avoid triggering any suspicion or regulatory reporting by the bureau de change or money services business (MSB) that processes the wire transfers.
Structuring or smurfing is a common technique used by money launderers to move funds across borders and disguise their origin and destination.
The other options are not necessarily indicative of money laundering, although they may require further investigation depending on the circumstances and the risk profile of the customers and countries involved.
Option A describes a regular and small wire transfer that may be legitimate, such as a remittance to a family member or a friend. Option Cdescribes a large volume of wire transfers that may be related to a seasonal or business activity, such as a holiday or a trade event. Option D describes a series of small wire transfers that may be coincidental or random, and do not necessarily add up to a significant amount.:ACAMS CAMS Certification Video Training Course - 6th Edition1 Exam CAMS: Certified Anti-Money Laundering Specialist (the 6th edition)2 ACAMS CAMS Study Guide - 6th Edition, Chapter 2, pages 36-37: https://www.acams.org/wp-content/uploads/2019/09/ACAMS-CAMS-Study-Guide-6th-Edition-Chapter-2.pdf

The Office of Foreign Assets Control (OFAC) sanctions are extraterritorial in nature, meaning that they apply beyond the national borders of the United States. OFAC sanctions are intended to restrict transactions and the movement of assets between the U.S. and designated persons and organizations. These sanctions are imposed to disrupt the economic and financial relations between foreign countries and designated persons, organizations, or countries. These sanctions include prohibiting transactions, requiring the blocking of assets, and implementing targeted measures such as arms embargoes, travel bans, and financial or commodity restrictions.
