According to FinCEN, when a financial institution identifies a suspicious activity that necessitates suspicious activity report filing, the SAR supporting documentation should:

While having written policies and procedures is important for effective compliance and operational consistency, this choice does not specifically address the requirement for the content of the SAR's supporting documentation. Policies alone do not ensure that all relevant records are included in the SAR filing process.

This option emphasizes the physical storage and organization of documentation rather than the content that needs to be included with the SAR. While secure storage is essential, it does not fulfill the requirement for including all pertinent documents that informed the determination to file a SAR.

This choice incorrectly suggests that the supporting documentation should be restricted to minimal information. In reality, the documentation must encompass all relevant records that led to the filing decision, which may extend far beyond just the account name and transaction details.
