The OZ Master Fund returned a net 10.4% in 2017, compared to a net 3.8% in 2016, earnings report data showed.
"Our primary focus is on building a pipeline of client mandates across all of our businesses and we believe that our strong performance should translate to inflows, although we cannot pinpoint the timing," he added.
Mr. Och also told analysts that "as this will be my last earnings call, I want to conclude with a few thoughts. I am proud of the firm that my partners and I built over the last 24 years. I plan to do all I can to continue to contribute to the firm's success. Together with our deep bench of investment talent and infrastructure support, I believe we are well-positioned for the future."
Robert S. Shafir succeeded Mr. Och as Och-Ziff's CEO on Feb. 5. He served as CEO of Credit Suisse Americas from 2008 to 2016.
