Clayton was sworn in May 4, 2017, and left the SEC as one of its longest serving chairs. He announced in mid-November that he planned to depart before year-end.
“I am humbled and honored to serve as the acting chairman,” Roisman said in a statement Monday. “During the time I am in this role, I am fully committed to maintaining the steady course that Chairman Clayton charted during his admirable tenure. I look forward to continuing to work with the incredible SEC staff and my fellow Commissioners as we steward this agency into the new year.”
During his time as SEC chairman, Clayton advanced more than 65 final rules. Chief among them were Regulation Best Interest and the Customer Relationship Summary form, or Form CRS.
Roisman is serving with Republican Commissioner Hester Peirce and Democratic Commissioners Allison Lee and Caroline Crenshaw, all of whom were nominated by Trump.
He was sworn in as a commissioner on Sept. 11, 2018, and likely won’t stay with the organization much longer.
