The OCC is issuing this final rule to amend its regulations implementing the Bank Secrecy Act (BSA) governing the confidentiality of a suspicious activity report (SAR) to: clarify the scope of the statutory prohibition on the disclosure by a financial institution of a SAR, as it applies to national banks; address the statutory prohibition on the disclosure by the government of a SAR, as that prohibition applies to the OCC's standards governing the disclosure of SARs; clarify that the exclusive standard applicable to the disclosure of a SAR, or any information that would reveal the existence of a SAR, by the OCC is to fulfill official duties consistent with Title II of the BSA; and modify the safe harbor provision in the OCC's SAR rules to include changes made by the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism (USA PATRIOT) Act. These amendments are consistent with a final rule being contemporaneously issued by the Financial Crimes Enforcement Network (FinCEN).
