FinCEN is issuing this final rule as a technical amendment to new Chapter X of Title 31 of the Code of Federal Regulations, which was published on October 26, 2010. After that date, FinCEN published two final rules in Part 103 of Title 31 of the Code of Federal Regulations, one concerning mutual funds and the other concerning the confidentiality of a report of suspicious activity (SAR). This final rule moves the SAR confidentiality rule from Part 103 to new Chapter X and addresses the compliance date of the mutual fund rule. Additionally, the Chapter X Final Rule contained an inadvertent typographical error that omitted several sections from Subpart C of Part 1026 Rules for Futures Commission Merchants and Introducing Brokers in Commodities. This final rule corrects those omissions.
