SEC officials said in the announcement their most significant enforcement actions in fiscal 2016 included insider-trading and beneficial ownership reporting-related charges against Leon G. Cooperman and Omega Advisors, and FCPA cases against Och-Ziff Capital Management Group. One of what they called "impactful first-of-their-kind actions" was against private equity firm Blackstreet Capital Management for engaging in brokerage activity related to portfolio companies without registering as a broker-dealer.
