On July 14, the OMB’s Office of Information and Regulatory Affairs (OIRA) concluded its review of a long-awaited FinCEN proposal to establish customer due diligence requirements for financial institutions, sending the rule back to FinCEN. In its spring 2014 rulemaking agenda, Treasury updated the timeline for the rule to indicate it could be proposed in July with a 60 day comment period. OIRA’s public records do not provide information about what, if any, changes OIRA sought or required prior to FinCEN finalizing the proposal. The public portion of the FinCEN rulemaking has been ongoing since February 2012 when FinCEN released an advance notice of proposed rulemaking to solicit comment on potential requirements for financial institutions to (i) conduct initial due diligence and verify customer identities at the time of account opening; (ii) understand the purpose and intended nature of the account; (iii) identify and verify all customers’ beneficial owners; and (iv) monitor the customer relationship and conduct additional due diligence as needed. FinCEN subsequently held a series of roundtable meetings, summaries of which it later published.
