REPORTING OF SUSPICIOUS TRANSACTIONS [https://www.fatf- gafi.org/media/fatf/documents
/recommendations/pdfs/FATF%20Recommendations%202012.pdf] If a financial institution suspects or has reasonable grounds to suspect that funds are the proceeds of a criminal activity, or are related to terrorist financing, it should be required, by law, to report promptly its suspicions to the financial intelligence unit (FIU). According to the Financial Action Task Force's (FATF) Recommendation 20, a suspicious transaction report (STR) or a suspicious activity report (SAR) is filed by a financial institution or, by a concerned citizen, to the local Financial Intelligence Unit if they have reasonable grounds to believe that a transaction is related to criminal activity.

According to the FATF typology report 2000-20011, lawyers can provide a range of functions that can be useful to a potential money launderer, such as:
Creating complex legal arrangements, such as trusts, foundations, or corporations, that can obscure the identity and ownership of the beneficial owners or the origin and destination of the funds.
Buying and selling property, such as real estate, art, or jewelry, that can be used to transfer or store illicit proceeds or to provide a legitimate cover for the source of funds.
Performing financial transactions on behalf of a client, such as opening bank accounts, transferring funds, issuing checks, or exchanging currencies, that can facilitate the movement or concealment of illicit funds.
Providing legal advice, on the other hand, is not a function that can be directly exploited by a money launderer, unless the advice is related to the above functions or to the avoidance or evasion of anti-money laundering laws and regulations.

According to the CAMS Study Guide, page 173, "If an independent investigation provides grounds to interview the employee, the employee can be interviewed and, if necessary, terminated, but not advised that he or she is under investigation by law enforcement." This is because informing the employee of the law enforcement investigation could compromise the integrity of the case and potentially expose the institution to legal liability. Therefore, option B is the correct answer.

A large cash deposit is a potential indicator of money laundering, especially if it is inconsistent with the customer's profile or behavior. Therefore, the bank should ask the customer about the source and purpose of the funds, and verify the information if possible. In this case, the customer claims to have sold a used car and received cash, which may be a reasonable explanation. However, the bank should not rely solely on the customer's statement, but should also monitor the account for any further cash transactions or suspicious activity that may indicate money laundering. For example, the bank should check if the customer withdraws the cash soon after the deposit, transfers the funds to other accounts or jurisdictions, or engages in structuring or smurfing to avoid reporting thresholds.
The bank should not do nothing, as this may expose the bank to regulatory or reputational risks, or facilitate money laundering. The bank should also not file a Suspicious Transaction Report (STR) unless there are other grounds to suspect money laundering, as this may be premature or unnecessary. The bank should not close the account before another issues arise, as this may be disproportionate or discriminatory, and may also alert the customer to the bank's suspicion.

Section 313 of the USA PATRIOT Act prohibits U.S. financial institutions from establishing, maintaining, administrating or managing correspondent accounts for foreign shell banks. A foreign shell bank is a foreign bank that does not have a physical presence in any country. To ensure compliance with this prohibition, U.S.
financial institutions must obtain from each foreign bank that maintains a correspondent account the identity of each owner of the foreign bank and the nature and extent of each owner's ownership interest. This information must be updated within 30 days of any change.
