On Monday, the SEC announced that Julie M. Riewe and Marshall S. Sprung will be the new Co-Chiefs of the Division of Enforcement's Asset Management Unit. Riewe and Sprung, who have been serving as deputy chiefs of the Asset Management Unit since May 2012, will together succeed former unit chief Bruce Karpati, who left the agency in May 2013 to join Prudential Financial as its chief compliance officer. The SEC created the Asset Management Unit in January 2010 to focus specifically on investigations involving investment advisors, investment companies, hedge funds, and private equity funds.

Riewe joined the SEC in 2005 after four years as a litigation associate at WilmerHale in Washington, D.C. In addition to her extensive work in the asset management area, Riewe led the SEC's insider-trading case against Mark Cuban. 

Sprung joined the SEC in 2003 after working for five years as a litigation associate at Gibson, Dunn & Crutcher in Los Angeles. He played a central role in the SEC's enforcement actions against investment adviser AXA Rosenberg and its founder, among other cases.
