August was not kind to Och-Ziff Capital Management, as the New York hedge fund saw both its performance and assets under management dip during the month.

Och-Ziff said its funds fell 0.91% on a blended basis in a filing with the Securities and Exchange Commission. Its flagship OZ Master Fund fell 0.53% last month, pushing it into the red year-to-date, down 0.36%. Its OZ Asia Master Fund fared even worse, losing another 4.11% in August to add to its year-to-date loss, which now exceeds 10%.

The firm’s assets under management also fell slightly, dropping $110 million to $33.2 billion as of the beginning of this month.
