The Office of Thrift Supervision (OTS) is amending its regulations that require savings associations and service corporations to file criminal referral and suspicious transaction reports. This final rule streamlines reporting requirements by providing that savings associations and service corporations file a new Suspicious Activity Report (SAR) with the OTS and the appropriate federal law enforcement agencies by sending SARs to the Financial Crimes Enforcement Network of the Department of the Treasury (FinCEN) to report a known or suspected criminal offense or a transaction that an institution suspects involves money laundering or violates the Bank Secrecy Act (BSA).
