The Financial Crimes Enforcement Network.GSE anti-money laundering, SARs reporting proposed. The Financial Crimes Enforcement Network proposed regulations that would require Fannie Mae, Freddie Mac and the Federal Home Loan Banks to develop anti-money laundering programs and file suspicious activity reports with FinCEN. The government-sponsored enterprises currently file fraud reports with their regulator, the Federal Housing Finance Agency, which then files SARs with FinCEN when the facts in a particular fraud report warrant a SAR under FinCEN’s reporting standards.
