This final rule changes existing references from ``Criminal Referral Form'' to ``Suspicious Activity Report'' to conform the language in the rule to the new Suspicious Activity Report (SAR) which the financial regulatory agencies and the Department of the Treasury have developed to replace the Criminal Referral Form (CRF). It also reduces the required retention period for SARs' and any attachment thereto from the current 10 years to 5 years. This final rule streamlines reporting requirements by providing that credit unions file a new SAR with NCUA and appropriate Federal law enforcement agencies by sending the SARs to the Financial Crimes Enforcement Network of the Department of the Treasury.
