The Egmont Group is a global network of 170 financial intelligence units (FIUs) that facilitate the exchange of information and cooperation among member FIUs to combat money laundering, terrorist financing, and associated predicate offences12. FIUs are national agencies that collect, analyze, and disseminate financial intelligence to relevant authorities3. The Egmont Group supports the implementation of international standards and best practices for FIUs, provides training and technical assistance, and promotes the development of secure and effective communication channels12.

The USA PATRIOT Act is a comprehensive legislation that was enacted in 2001 to enhance the powers and tools of the US authorities to combat money laundering, terrorist financing, and other threats to the national security and the integrity of the financial system. The USA PATRIOT Act contains several provisions that affect the relationship between US banks and foreign banks that maintain correspondent accounts in the US.
One of these provisions is Section 319, which allows the US authorities to seize the funds of a foreign bank held with a US bank, if the foreign bank refuses to comply with a subpoena or a request for records related to the correspondent account. This provision is intended to prevent foreign banks from using their correspondent accounts in the US to facilitate transactions involving tainted funds, such as proceeds of crime, funds intended to support terrorism, or funds subject to sanctions or asset freezing orders. Section 319 also requires US banks to maintain records of the owners and agents of foreign banks that have correspondent accounts with them, and to terminate such accounts if requested by the US authorities.
Therefore, if a foreign bank maintains a correspondent account in the US, and the US authorities find out that the account has been used to facilitate a transaction involving tainted funds, the US authorities can seize the funds of the foreign bank held with the US bank, under the authority of the USA PATRIOT Act.

These two options are potential red flags for money laundering or terrorist financing because they could indicate an attempt to avoid the reporting threshold of $10,000 for cash transactions, or to conceal the source or origin of the funds. According to the ACAMS Study Guide, some common indicators of money laundering are:
Transactions structured to avoid recordkeeping or reporting requirements Transactions inconsistent with the customer's profile or business activity Transactions involving the use of multiple accounts or locations Transactions involving high-risk jurisdictions or entities Transactions involving cash or complex crypto assets The other two options are not necessarily red flags by themselves, as they could have legitimate explanations.
For example, the restaurant could be located in a different city because of market demand, or the new account could demonstrate a steady flow of income because of the success of the business.

According to the ACAMS Study Guide 6th Edition, Chapter 2, page 37, one of the red flags of money laundering or terrorist financing is the use of nominees, trusts, or third parties to hide the identity, ownership, or control of the funds or assets involved in the transaction. Nominees are individuals or entities that act on behalf of the actual or beneficial owners of a company, trust, or account, and may be used to conceal the source, destination, or purpose of the funds or assets. Nominees may also be used to evade taxes, sanctions, or regulatory requirements.
In this case, the compliance officer is unable to verify the identity of the beneficial owners of the company, and only information on the nominee owners was provided. This raises the suspicion that the company may be involved in money laundering or terrorist financing activities, and that the nominee owners may be acting as fronts or intermediaries for the actual or beneficial owners. The compliance officer should conduct further due diligence on the company, the nominee owners, and the beneficial owners, and report any suspicious or unusual activity to the relevant authorities.
