On March 1, 2011, FinCEN transferred its regulations from 31 CFR Part 103 to 31 CFR Chapter X as part of an ongoing effort to increase the efficiency and effectiveness of its regulatory oversight. 31 CFR Chapter X is organized by generally applicable regulations and by industry-specific regulations. There have been no substantive changes made to the underlying regulations as a result of this transfer and reorganization. Please note that documents published prior to March 1, 2011 will continue to contain citations to 31 CFR Part 103.
