On April 3, the FSOC approved a final rule and interpretive guidance on its authority to require supervision and regulation of certain nonbank financial companies.  Section 113 of the Dodd-Frank Act authorizes the FSOC to require a company to be subject to Fed supervision if the FSOC determines that material financial distress at the company, or the characteristics of the company, could pose a threat to U.S. financial stability.  Treasury Release.  Final Rule.
