Prosecutors: Former Och-Ziff Hedge Fund Owes Investors Restitution (Pensions&Investments) Hedge fund Sculptor Capital Management Ltd. should pay a group of former investors “at least $150 million” to restore losses suffered when the firm formally known as Och-Ziff Capital Management was convicted in a bribery scheme, said lawyers for the Department of Justice. The government’s position in a court filing Nov. 22 represents a departure from a March 2018 filing that it had not concluded the former shareholders of the now-defunct Canadian mining company Africo Resources Ltd. were entitled to restitution because they had not proved the cause and degree of harm after they lost rights to an African mine during the bribery scandal.
