Financial institutions are required to file Suspicious Activity Reports to report transactions they have reason to suspect are illegal. Under the auspices of the Bank Secrecy Act Advisory Board, the Treasury Department's Financial Crimes Enforcement Network periodically publishes the SAR Activity Review.
The document serves a number of purposes. It assists those who might have to file an SAR in identifying suspicious activity and accurately complete the report. How law enforcement agencies make use of the data is also presented. By providing feedback to the industry, and showing how the reporting efforts integrate with law enforcement activities, there is an opportunity to better prevent or detect fraud.
