According to the ACAMS CAMS Certification Study Guide (6th edition), one of the challenges of information sharing within a financial group is the compliance with privacy and data protection rules that may vary across jurisdictions. Therefore, before sharing information about a customer with an affiliate, a bank should consider whether such sharing is permitted by the applicable laws and regulations, and whether the customer has consented to it. The other options are not relevant factors for information sharing in the case of an investigation.

Physical certificates are documents that represent ownership of securities, such as stocks or bonds, that are issued by a company or a government. Physical certificates present a money laundering risk to broker-dealers for two reasons:
* The trade information on a physical certificate can be easily altered, such as the name of the owner, the date of issuance, or the number of shares. This can facilitate the concealment or falsification of the origin, ownership, or value of the securities, and enable the laundering of illicit funds through the purchase or sale of the securities.
* Physical certificates may be provided to nominees for deposit or settled in off-market transactions, such as private placements, bearer bonds, or direct transfers. This can bypass the normal reporting or recordkeeping requirements of the broker-dealer, and avoid the scrutiny or verification of the identity, source of funds, or beneficial ownership of the securities.

Money laundering can have serious consequences for financial institutions. They may face increased investigation costs and fines from regulators and law enforcement agencies for failing to detect or prevent money laundering activities. Additionally, money laundering can result in a loss of profitable business as customers and counterparties may no longer want to do business with the institution due to its reputation for being associated with illicit activity.

When a high volume of incoming wire transfers generates an alert about a client and the funds are immediately debited by cash withdrawals and outgoing wire transfers, the first information that should be reviewed to investigate this alert/case is the customer's account activity. This is because the account activity can reveal the origin, destination, purpose, frequency, and amount of the wire transfers, as well as any unusual or inconsistent patterns that may indicate money laundering or fraud. The account activity can also help to compare the wire transfers with the customer's profile, risk rating, expected behavior, and source of funds.
Reviewing the account activity can help to determine if the alert is a false positive or a true positive, and if further investigation or reporting is required.

According to the ACAMS CAMS Certification Study Guide (6th edition), one of the red flags for money laundering is the structuring of cash transactions to avoid reporting thresholds. Structuring is the practice of breaking down large amounts of cash into smaller deposits or withdrawals that are below the reporting threshold of $10,000 in the United States or equivalent amounts in other jurisdictions. Structuring is done to evadethe detection and reporting of cash transactions by financial institutions to the authorities. Therefore, when an accountable institution identifies that a customer is engaging in structuring or other forms of cash transaction manipulation, it should file a SAR/STR to report the suspicious activity1
